Problems solved by technology

The disadvantages of this separation mechanism are: ① At the contact point with the toothed oval wheel (or other shaped toothed wheels), the rod (ie steel bar) has a large amplitude
Due to the large local amplitude, the steel bar is easily broken, and the frame is also easily cracked from the weld seam, and the life of the whole machine is short
②During the whole separation process of potatoes, the friction between the soil, potatoes and steel bars is relatively large, the friction time is long, and the potatoes are seriously damaged by rubbing
The soil and potatoes fall to the ground at the same time, the rate of clear potatoes is low, and the missed harvest is serious
④ consumes a lot of power
Due to the multi-stage transmission, the friction time between the potatoes and the conveyor belt is long, the potatoes are seriously damaged by rubbing, and the traction power consumed is generally large.

Embodiment Construction

[0024] The invention provides an automatic control potato harvester. exist figure 1 In the top view of the overall structure of the potato harvester shown, the digging shovel 1 and the depth-gauge wheel 7 of the potato harvester are fixed on the front part of the frame 6, and the transmission device 2 is fixed on the frame 6 obliquely upward behind the digging shovel 1 , the potato-soil separation mechanism 3 is fixed on the frame 6 with a slight downward slope behind the transmission device 2, the guide groove 4 is fixed on the connecting plate 14 at the rear and lower part of the potato-soil separation mechanism 3, and the traveling wheels 5 are fixed on the rear of the frame 6 . When working, the potato harvester moves forward, and the digging shovel 1 scoops up the potato soil, and sends it to the transmission device 2 driven by the stepping motor, and the transmission device 2 lifts the potato soil to a specified height and has a relatively high Reasonable speed of move...

Abstract

The invention relates to an automatic control potato harvester, formed by a digging shovel, a transmitter, a potato-soil separator, a guide groove, a frame, a depth limiting wheel, and walking wheels. The separator is driven by the straight motor. The invention comprises a stable part and a vibrating part, wherein, the vibration screen of vibrating part is sheet structure, while the amplitude is controlled by the compressed amount of damping spring in the stable part and the frequency is controlled by the electrical signal input into the straight motor. The separator utilizes the mechanical resonance theory. The invention will not hurt the potato, with less steel consumption and long service life.

Description

technical field [0001] The invention belongs to the technical field of crop harvesting and agricultural mechanization. In particular, it relates to an automatic control potato harvester. Background technique [0002] In our country, the potato harvester is mechanical. Most of the separation of potato and soil adopts the combination of rod chain type vibration separation mechanism and sieve type swing separation mechanism. The vibration is driven by a toothed ellipse wheel (or other shape of the toothed wheel) mounted on the frame. The shortcoming of this separation mechanism is: 1. at the contact point with the toothed oval wheel (or the toothed wheel of other shapes), the bar (ie steel bar) has a large amplitude of vibration. At some distance from the toothed ellipse (or other shape of the toothed wheel), the bar has little or no vibration at all. Due to the large local amplitude, the steel bar is easily broken, and the frame is also easily cracked from the welding seam...
