Description

Single grain pen seeder

technical field

The invention belongs to the technical field of agricultural scientific research sowing, and in particular relates to a precision single-grain pen-type seeder.

Background technique

Potted plants are a commonly used experimental technique in plant cultivation research, especially in research that requires high precision and theoretical exploration in field research. Sowing is a key link in pot experiments, which directly affects whether subsequent experiments can be carried out smoothly. There are two main traditional sowing methods: one is the tweezers sowing method, which is not only labor-intensive, but also the depth of the sowing cannot be controlled, and the germination rate of the seeds is low, and the emergence of seedlings is inconsistent; There is a small seeder that puts the seeds in the seedbed at one time. Although the work efficiency is improved and the labor intensity is reduced, there is a problem that the sowing density cannot be controlled. Therefore, it is urgent to develop a fast and accurate pot test seeder.

The grip rod is a hollow structure, divided into upper and lower parts, the upper part is cylindrical, the lower part is trapezoidal, the two parts are fixedly connected, the end of the lower part is fixedly connected with the shell, and a spring piece is provided in the middle of the inner side of the trapezoidal part of the grip rod . The ejector rod passes through the grip rod longitudinally, and the ejector rod is divided into an upper part and a lower part, which are connected by a hinged ball. There is a clip, and a spring is arranged on the outer periphery of the push rod between the clip and the housing. The shell is oblate, the right side of the center of the top is connected to the bottom of the funnel, the left side of the top is connected to the bottom of the trapezoidal inner cavity of the handle in a counterclockwise direction of 10°-30°, and the right side of the center of the bottom is connected to the seed tube. The shaft secures the seed catcher and toggle wheel in the center of the housing. Described seed catcher is disc-shaped, and its diameter is less than shell diameter 1-4mm, and the outer periphery of seed catcher is equidistantly provided with a concave seed groove with six apertures slightly larger than seed, adjacent seed groove 15 centers The angle between the radial lines is 60 degrees. The toggle wheel is a regular hexagonal special-shaped wheel with a diameter smaller than that of the seed catcher. The first included angle is 120°, and the second included angle is 60°. The toggle wheel is fixedly connected with the seed catcher. The layout of the concave seed troughs is arranged alternately with the corners of the toggle wheel. The seed troughs are designed according to the maximum seed diameter for sowing, and are equipped with a variety of seed troughs with gradually reduced diameters, which can be configured according to actual needs.

further

The internal cavity of the toggle wheel is provided with anti-retrograde internal teeth, and a steel wire is arranged on the shaft to bear against the internal teeth in a curved elastic shape, so that the toggle wheel can only rotate counterclockwise.

further

One side of the seed tube in the lower part of the housing is provided with a depth controller. The depth controller is composed of a support plate, a connecting rod and a screw knob. The center of the support plate is provided with a positioning hole with a diameter greater than 2-3mm of the seed tube. The bottom is fixedly connected with the support plate, the upper part of the connecting rod is provided with a sliding groove, and the connecting rod is provided with a distance scale from the bottom end, the depth controller is fixed on the shell by the screw knob, and the height of the supporting plate is adjusted through the sliding groove to determine the sowing depth.

Beneficial effects of the present invention: (1) The present invention enables seeds to leak out of the seed tube in the form of single grains from the funnel by setting the seed catcher device, thereby achieving the effect of precisely controlling the sowing density. (2) By designing an anti-reverse device on the pulling wheel, the present invention can make the pulling wheel rotate in one direction, further ensuring that the seeds can leak out of the seed tube accurately, and greatly improving its working efficiency and accuracy. (3) The present invention is equipped with a depth controller capable of controlling the sowing depth, which can improve the quality of sowing and the accuracy of the experiment for the experimental researchers who are engaged in experiments with high requirements for accuracy. (4) The ejector rod of the present invention is provided with a spring device, which can achieve the effect of cycle operation.
