Abstract

An automatic and continuous rubber extracting device comprises a first grinding stone having a central opening and second grinding stone rotatable mounted against the first grinding stone. The first grinding stone is a top stone and the second grinding stone is a bottom stone. A cone is disposed within the central opening of the first grinding stone. A motor apparatus is provided for rotating the bottom stone and the cone. A screw feed is in communication with the central opening of the first grinding stone. Plant material from the screw feed is fed along the cone and between the first grinding stone and second grinding stone. The cone may be provided with grooves and recesses along an lateral surface thereof.

Claims

1. A device for grinding organic material, the device comprising:

a first grinding disk having a central opening;

a second grinding disk disposed adjacent to and against the first grinding disk;

a substantially cone shaped member disposed within the central opening of the first grinding disk, the cone shaped member having a base edge which engages a nip opening between the first grinding disk and the second grinding disk;

a motor apparatus operatively engaging and rotating the cone shaped member and at least one of the first grinding disk and the second grinding disk; and

a feed tube in communication with the central opening in the first grinding disk wherein the organic material fed through the feed tube is moved along a lateral surface of the cone shaped member and between the first grinding disk and the second grinding disk and wherein the feed tube is a telescoping feed tube which includes an outer feed tube and an inner feed tube, the outer feed tube being in communication with an input conduit and the inner feed tube having a lateral opening which is aligned with the input conduit to allow material to be fed into the device when the inner feed tube is substantially retracted within the outer feed tube and wherein the input conduit does not communicate with the inner feed tube and material cannot be fed to the device through the input conduit when the inner feed tube extends outwardly of the outer feed tube.

2. The device as claimed in claim 1 further including an auger disposed in the feed tube.

3. The device as claimed in claim 2 wherein the auger is mechanically coupled to the cone shaped member and rotates with the cone shaped member.

4. The device as claimed in claim 3 further including a blade disposed between the auger and the cone shaped member.

5. The device as claimed in claim 4 wherein the blade is mechanically coupled to the cone shaped member and rotates with the cone shaped member.

6. The device as claimed in claim 1 further including a scraper mounted on an apex of the cone shaped member.

7. The device as claimed in claim 1 wherein the input conduit extends angularly from the outer feed tube.

8. The device as claimed in claim 1 further including a groove in the lateral surface of the cone shaped member.

9. The device as claimed in claim 8 wherein the groove extends from an apex of the cone shaped member to a base edge thereof.

10. The device as claimed in claim 9 further including an elongate recess in the lateral surface of the cone shaped member extending generally perpendicular to the groove.

11. The device as claimed in claim 1 wherein the first grinding disk is a stationary top grinding stone and the second grinding disk is a rotatable bottom grinding stone.

12. A device for grinding organic material, the device comprising:

a first grinding disk having a central opening;

a second grinding disk disposed adjacent to and against the first grinding disk;

a substantially cone shaped member disposed within the central opening of the first grinding disk;

a motor apparatus operatively engaging and rotating the cone shaped member and at least one of the first grinding disk and the second grinding disk; and

a scraper mounted on an apex of the cone shaped member, an output shaft being coupled to the scraper and causing the scraper to be moved along a lateral surface of the cone shaped member; and

a telescoping feed tube in communication with the central opening in the first grinding disk, the telescoping feed tube including an outer feed tube and an inner feed tube, the outer feed tube being in communication with an input conduit and the inner feed tube having a lateral opening which is aligned with the input conduit to allow material to be fed to the device when the inner feed tube is substantially retracted within the outer feed tube, wherein the input conduit cannot communicate with the inner feed tube and material cannot be fed to the device through the input conduit when the inner feed tube extends outwardly of the outer feed tube, and wherein the organic material fed from the telescoping feed tube is moved along the lateral surface of the cone shaped member and between the first grinding disk and the second grinding disk.

13. The device as claimed in claim 12 wherein the first grinding disk is a stationary top grinding stone and the second grinding disk is a rotatable bottom grinding stone, and the second grinding stone has grooves on a grinding surface thereof.

14. A device for grinding organic material, the device comprising:

a first grinding disk having a central opening;

a second grinding disk disposed adjacent to and against the first grinding disk;

a substantially cone shaped member disposed within the central opening of the first grinding disk,

a groove extending along a lateral surface of the cone shaped member from an apex of the cone shaped member to a base edge of the cone shape member;

an elongate recess in the lateral surface of the cone shaped member, the elongate recess extending generally perpendicular to the groove;

a motor apparatus operatively engaging and rotating the cone shaped member and at least one of the first grinding disk and the second grinding disk; and

a feed tube with an auger disposed therein in communication with the central opening in the first grinding disk wherein the organic material fed from the feed tube is moved along the lateral surface of the cone shaped member and between the first grinding disk and the second grinding disk.

15. The device as claimed in claim 14 wherein the auger is mechanically coupled to the cone shaped member and rotates with the cone shaped member.

16. The device as claimed in claim 14 wherein the first grinding disk is a stationary top grinding stone and the second grinding disk is a rotating bottom grinding stone.
