Special-purpose farm work rake for farm work machine in salt pan

Abstract

The invention relates to a salt-raking mechanism which carries out farm work on salt bed, can carry out full stubble on the salt bed and crushes salt surface layer. Its work principle is as follows: output power of a gearbox of the farm work machine is transmitted through an universal shaft coupling to a decelerator fixed on a rake body of the farm work machine and then is transmitted to a main shaft of the rake body. The main shaft is provided with a driving wheel which is respectively engaged with two driven gears. Each driven gear is connected with a crank through an eccentric shaft. Each crank is connected with a connecting rod, which is connected with a row of rake. Simultaneously, in order to prevent from destroying a salt pan base plate, rake teeth are made into a hook shape. The design of the invention has the following advantages and positive effects: the farm work rake can reciprocate from side to side and swing while moving forward with the farm work machine, so as to drive the rake to carry out stubble operation on the salt bed. The swing frequency can be adjusted by the gearbox of the farm work machine, so as to fully and uniformly carry out the stubble operation with high efficiency. In addition, the rake body can be folded such that the farm work machine is convenient to operate outside the salt pan.

Description

Technical field [0001] The invention relates to a salt rake mechanism for carrying out active stubble operations on salt layers in salt fields. In particular, it can enable the salt layer to be fully stubbled, break the salt surface layer, make the stubble more sufficient, and be more conducive to the crystallization growth of salt, thereby improving the Salt quality and yield. Background technique [0002] The existing salt field stubble machine uses a stubble rake fixedly connected behind the salt machine, and the stubble machine moves forward to drag the rake to achieve the purpose of stubble operation. The rake body does not move, and the stubble operation effect is not ideal, and The need to repeat work back and forth is not only time-consuming, labor-intensive and inefficient, but also increases the labor intensity of salt field workers. Moreover, the rake body is very long, making it inconvenient to drive outside the salt fields. Contents of the invention [0003]...

Problems solved by technology

[0002] The existing stubble machine in Yantian is fixedly connected with the stubble rake behind the salt machine, and the stubble machine is driven forward to drag the rake to achieve the purpose of stubble. The rake body does not move, and the stubble operation effect is not ideal. It is necessary to repeat the work back and forth, which is not only time-consuming, labor-intensive and inefficient, but also increases the labor intensity of Yantian operators

And the rake body is very long, it is inconvenient to drive outside the salt pan
