Embodiment 1

[0037] Hydraulic drive has been widely used in various fields, and it has also been widely used in agricultural machinery in recent years. Most of the agricultural machinery used for farmland operations is equipped with a closed hydraulic system. The existing farmland operation machinery is driven by a closed hydraulic motor to drive the road wheels to travel in the farmland. Once the hydraulic motor fails, the road wheels will be locked and unable to rotate due to the connection with the hydraulic motor, making the farmland operation machinery unable to move. Towed by a trailer, it can only be overhauled on site or forcibly towed, which greatly increases the cost and difficulty of subsequent overhauls. The device for preventing road wheel locking in this embodiment has a reasonable structural design, simple principle, and is economical and applicable. It can completely solve the fatal problem that a farmland operation machine with a hydraulic motor failure cannot be dragged, a...

Embodiment 2

[0043] The device for preventing road wheel locking of the present embodiment has the same basic structure as that of Embodiment 1, the difference being that:

[0044] The drive shaft 1 is driven to rotate by the internal combustion engine.

[0045] In non-hydraulic driven farmland operation machinery, when the power output mechanism breaks down, although the road wheels 3 can still rotate in most cases, sometimes when the power output mechanism is completely stuck, it will directly cause the road wheels 3 to be locked and die. Can't rotate, thereby can't drag this farmland operation machinery, perhaps even if road wheel 3 still can rotate, but because road wheel 3 is connected with power take-off mechanism, will certainly increase the resistance that road wheel 3 is subjected to when rotating, has increased dragging. The difficulty of moving this farmland operation machine is time-consuming and laborious; and when dragging this farmland operation machine, the traveling wheel ...

Embodiment 3

[0049] The device for preventing road wheel locking of the present embodiment has the same basic structure as that of Embodiment 1, the difference being that:

[0050] In order to ensure that the traveling wheel 3 can rotate normally on the boss 202 when the hydraulic motor breaks down, the width of the traveling wheel main body 301 is less than 1 mm from the distance between the outer disc 4 and the inner disc 2; 0.3mm outer diameter.

Abstract

The invention discloses a device for preventing walking wheels from locking, and mainly relates to the field of agricultural machines. The device for preventing the walking wheels from locking comprises a driving rotating shaft, an inner disc, the walking wheels and an outer disc. The inner disc comprises an inner disc body and a boss, a through hole is formed in the inner disc body, and the boss is arranged on one side face of the inner disc body and is an annular protrusion which is distributed around the through hole in the inner disc body. The driving rotating shaft penetrates into the through hole in the inner disc body and is fixedly connected with the inner disc and used for driving the inner disc to rotate. The walking wheels comprise walking wheel bodies, through holes are formed in the walking wheel bodies and matched with the boss, the inner disc is detachably connected with the walking wheels and the outer disc, and the walking wheel bodies are limited between the outer disc and the inner disc. The troubling problem that for a long time, a power output mechanism fails and locks the walking wheels is solved.

Description

technical field [0001] The present invention mainly relates to the field of agricultural machinery, generally various walking machines, such as rice transplanters, rice seedling trucks, spreading trucks, etc., and more specifically relates to a device for preventing road wheels from locking. Background technique [0002] With the state increasing investment subsidies for agriculture, modern farmland operation machinery is entering the hands of farmers. The emergence of farmland operation machinery solves the shortage of labor force and improves production efficiency and agricultural precision. Farmland operation machinery is an important production tool in agricultural production and one of the important means to ensure high agricultural yields and harvests. The classification method of farmland operation machinery can generally be divided into: manpower farmland operation machinery, animal power farmland operation machinery, small power farmland operation machinery, tracto...
