Description

Technical Field

[0001] The utility model relates to the technical field of soil turning devices for agricultural machinery, in particular to a soil turning device for agricultural machinery. Background Art

[0002] The soil turning device for agricultural machinery is a device that turns the soil, loosens it and removes weeds to promote land ventilation and improve soil fertility.

[0003] The tiller drives the rotating shaft to rotate through the engine, and then drives the plowshare or blade to turn the soil and turn the soil over. However, in the prior art, when turning the soil, the soil is only turned over by the blade, and the turned over soil blocks are broken up by the length of time the blade stays. However, the degree of soil block breakage is directly related to the rotation speed and residence time of the blade, but it cannot be effectively controlled. In order to work efficiently, it is necessary to accelerate the efficiency of turning the soil, and the residence time cannot be too long, which leads to the presence of some larger soil blocks when the soil blocks are broken. In order to ensure that the soil blocks are loosened and broken for subsequent planting, they need to be broken manually, resulting in a waste of manpower. Therefore, we propose a tiller for agricultural machinery. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a soil-turning device for agricultural machinery, which solves the problem that in order to carry out efficient work, the efficiency of soil turning needs to be accelerated, resulting in the presence of some large soil clods when the soil clods are broken. In order to ensure that the soil clods are loosened and broken for subsequent planting, manual subsequent crushing is required.

[0024] The embodiment of the present application provides a soil-turning device for agricultural machinery, which solves the problem that in order to work efficiently, it is necessary to accelerate the soil-turning efficiency, and its residence time cannot be too long, which leads to the existence of some large soil blocks during soil block crushing. In order to ensure that the soil blocks are loosened and crushed for subsequent planting, it is necessary to manually crush them later, resulting in a waste of manpower. The soil blocks are collected through the collection box 401. There is an earth outlet at the bottom end face of the collection box 401. The soil blocks turned over are collected in the collection box 401, and the smaller soil blocks fall through the earth outlet. The main bevel gear 501 is driven to rotate by the driving mechanism, so that the main bevel gear 501 drives the driven bevel gear 502 to rotate, and then the transmission shaft 506 drives the crushing roller 402 to rotate. The larger soil blocks are crushed by the crushing roller 402 to avoid the appearance of larger soil blocks that need to be manually crushed later.

The larger soil blocks are crushed by the crushing roller 402.

[0030] A transmission chain connected to the driving mechanism is arranged in the frame shaft 3. The driving mechanism drives the turning shaft 101 in the frame shaft 3 to rotate, so that the blade 1 rotates to turn the soil.
