A kind of uniform seeding equipment based on inverse proportional change and total amount constant

Abstract

The invention discloses a uniform sowing equipment based on the inverse proportional change and the total amount is constant. The moving rollers are slidingly connected, the ground support is erected on the rear and lower part of the axle frame and connected by electric welding, and the push rod is erected on the rear upper part of the wheel axle frame and connected by electric welding. Through the inverse ratio self-adjusting seed storage device, the present invention can adjust the diameter corresponding to the seed outlet according to the amount of seeds and the height of the accumulation of seeds in the storage cylinder. The seeds are under greater pressure, the flow rate is large, the flow rate is small, and the amount of seeds decreases, the discharge port gradually becomes larger, the flow rate is small, the flow rate is large, and the total amount is the same principle, so that uniform sowing can be achieved, and uniform feeding can be reduced The damage caused by the device to the seeds ensures the survival rate of the seeds.

Description

technical field [0001] The invention relates to the field of sowing equipment, more precisely, it is a kind of uniform sowing equipment based on the inverse ratio change and the total amount is constant. Background technique [0002] Along with the mechanization of agriculture, there are various planters on the market, and the sowing efficiency can be effectively improved by using the planter to sow, but the seeding equipment of the prior art still has the following defects; [0003] 1. The sowing equipment in the prior art generally stores the seeds to be sown in the tube, and then uses the gravity of the seeds to fall to achieve sowing. However, due to the pushing of the seeds in the storage tube, the seeds are subjected to downward force as the seeds remain. Due to the change of the quantity, the speed of seed sowing gradually slows down, and it is impossible to achieve more uniform sowing; [0004] 2. Or use the uniform feeder to solve the problem of uniform sowing, but...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a uniform sowing device based on the inverse proportional change and the total amount is constant, so as to solve the problem that the sowing device in the prior art generally stores the seeds to be sown in the cylinder and reuses the seeds themselves However, due to the pushing of the seeds in the storage cylinder, the downward force on the seeds changes with the change of the remaining amount of seeds, resulting in the gradual slowing of the seed sowing speed and the inability to achieve more uniform sowing; or The problem of uniform sowing is solved by the uniform feeder, but the seeds distributed by the uniform feeder are damaged to a certain extent, which may cause damage to the seeds and prevent germination, resulting in waste of seeds and affecting the defect of sowing uniformity
