Description

Rice transplanter backstop ware

Technical Field

The utility model mainly relates to the technical field of auxiliary parking of agricultural machinery, in particular to a backstop device of a rice transplanter.

Background

The existing agricultural machines such as rice transplanter have power transmission devices during working, but when parking, if the ground is uneven, the risk of vehicle slipping is likely to occur.

Because the operation of the transplanter has obvious periodicity and seasonality, the transplanter is in a parking storage state for most of the time every year, and the sliding risk exists if the parking position is not selected properly or the transplanter is not parked properly.

For example, the Chinese patent application (application No. CN201920366101.3, 5.5.2019) discloses an intelligent high-speed transplanter, which discloses a high-speed transplanter operation fault alarm stopping device.A rotating speed encoder is arranged at the upper end of each chain rotary box, a processor and a controller are arranged below a steering wheel, pulse signals measured by the rotating speed encoder transmit numerical values to the controller through the processor, the controller compares the numerical values, if the numerical values are greater than a set value, the controller does not act, and if the numerical values are smaller than the set value, the controller drives an transplanting control mechanism and a parking control mechanism, so that the transplanting stop and the machine stop are realized. However, this mechanism is mainly used to assist an unmanned high-speed rice transplanter based on navigation, and cannot realize fixation during a normalized stop.

For example, the invention patent of China (application number: CN201110109840.8, application date 29/4.2011) "a backward protection device for a high-speed riding type rice transplanter", discloses a backward protection device for a high-speed riding type rice transplanter, which comprises an instrument panel, a floating plate, a transplanting mechanism driving box, an HST control arm, a first connecting rod combination, a main speed change guide plate, a second connecting rod combination and a conversion arm combination, wherein a resisting plate is arranged at the tail part of the rice transplanter through a rod and a spring, one end of an actuating plate is arranged on the rod through a pin, the other end of the actuating plate is connected with the rotating arm combination through a pull wire, the middle part of the actuating plate is fixed on the transplanting mechanism driving box through a supporting pin, and the actuating plate rotates around the pin and the supporting pin. When the rice transplanter retreats, the resistance plate can quickly press the rod to move forwards when the rice transplanter retreats and is accidentally damaged, and then a series of braking actions are completed, so that the machine stops automatically when the barrier does not collide other parts of the machine, and the rice transplanter is well protected from being damaged. However, the application scene is limited to the movement process, and does not relate to the prevention of the 'secondary' sliding of the rice transplanter after parking.

For this reason, those skilled in the art have made an effort to develop a simple and convenient mechanism capable of preventing the rice transplanter from slipping down when the rice transplanter is parked.
