Dual material dispensing assembly
First Claim
1. A dual material dispensing assembly for a planting apparatus having a frame comprising in combination, an elongate body member, frame mounting means to mount said elongate body member on said frame, a pivot bracket pivotally mounted on said elongate body member, a first dispensing means for dispensing fertilizer including a first dispensing means knife adjustably mounted on said pivot bracket, a first dispensing means tube mounted adjacent said first dispensing means knife, an adjustable hydraulic biasing and trip release means connected between said pivot bracket and said frame mounting means, a second dispensing means for dispensing seed including a seed knife mount fixed to said elongate body member, a seed knife bolt plate mounted on said seed knife mount, a seed knife mounted on said seed knife mount, a seed tube mounted on said seed knife mount rearwardly of said seed knife, a limit stop mounted on said second dispensing means to limit the rearward travel of said first dispensing means relative to said second dispensing means, a tether between said second dispensing means and said first dispensing means to limit their separation, an adjustable depth gauge packer means fixed to said seed knife mount rearwardly of said second dispensing means whereby two different materials fed separately into said first dispensing means and said second dispensing means will be planted and compacted at precise levels separate and apart from one another.

Abstract
A dual dispensing device to be attached to the frame of an apparatus for seed and fertilizer placement in the ground comprising an elongate body member to be pivotally connected to the frame of the apparatus, a first dispenser for fertilizer is pivotally connected to the elongate body member, the first dispenser includes a first knife to make a first furrow in the ground and a first tube to carry fertilizer to be deposited in the first furrow. A fluid biasing element is pivotally connected to the first knife and to the frame to control the pivoting of the first knife. A second dispenser for seed is fixed to the elongate body member to the rear of the first dispenser, the second dispenser includes a second knife to make a second furrow in the ground and a second tube to carry seed to be deposited in the second furrow. Prior to the seed entering the seed tube the seed passes through a seed and air deceleration and air removal chamber. An adjustable gauge/packer wheel is fixed to the elongate body member to the rear of the seed dispenser.
