Description

Technical Field

[0001] This utility model belongs to the field of agricultural trailer technology, and specifically relates to an agricultural self-unloading trailer. Background Technology

[0002] Agricultural vehicles towed by tractors to transport materials, also known as agricultural trailers, are an important mode of mechanized transportation in rural China. Small wheeled or hand-held tractors tow small trailers for short-distance or field transport in rural areas.

[0003] Agricultural trailers come in various types and generally have functions such as unloading, spreading, or loading. Currently, self-dumping trailers that can automatically unload materials are designed for side or rear tipping. However, since they can only achieve one unloading direction, the trailer position needs to be constantly adjusted when unloading is required at multiple locations, resulting in inefficiency.

[0004] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, they have been modified and improved. At the same time, in the spirit and concept of seeking the best, with the assistance of professional knowledge and experience, and after a lot of ingenuity and experimentation, this utility model was created to provide an agricultural self-unloading trailer to solve the above-mentioned problems.

The supporting ball is provided with a slot, and a pin is provided in the slot. The ball seat is provided with a corresponding insertion hole, and the pin is inserted into the insertion hole.

[0011] As a preferred embodiment of an agricultural self-unloading trailer, a positioning hole is provided near the end of the pin, and a positioning pin is provided in the positioning hole.

[0012] Using the above scheme, when the support ball parts at the four corners of the upper end of the tractor frame are all inserted with pins after being fitted with ball seat parts, the truck bed is in a horizontal state. When the support ball parts on any side of the tractor frame are not fixed with pins, the hydraulic cylinder, as the actuator, drives the truck bed to rise, which will realize side tipping unloading. When the support ball parts at any end of the tractor frame are not fixed with pins, the hydraulic cylinder drives the truck bed to rise, which will realize rear tipping unloading.

[0013] As a preferred embodiment of an agricultural self-dumping trailer, the tractor frame includes several crossbars, with annular members between the crossbars and adjacent crossbars. Axles are provided at both ends of the annular members, and axle seats are provided on the crossbars corresponding to the axles. The axles are fitted into the axle seats, and the hydraulic cylinder is slidably fitted into the annular members.

[0014] In a preferred embodiment of an agricultural self-unloading trailer, the hydraulic cylinder is provided with shafts at both ends, and the annular component is provided with shaft holes corresponding to the shafts, with the shafts fitting into the shaft holes.

[0015] As a preferred embodiment of an agricultural dump trailer, the output end of the hydraulic cylinder is equipped with a universal joint, and the hydraulic cylinder cooperates with the trailer bed through the universal joint.

[0016] Using the above scheme, the ring component and the universal joint cooperate to achieve the stability of the hydraulic cylinder, thereby achieving the side or rear tipping of the truck bed.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are: the agricultural self-unloading trailer proposed by this utility model can achieve both side tipping and rear tipping, which greatly improves the use needs in different scenarios.

[0018] The four corner support balls and hydraulic cylinders at the upper end of the tractor frame serve as supports to achieve the balance of the truck bed. The support balls and ball seats are fixed together by pins. By removing the pins at different positions and cooperating with the hydraulic cylinders, unloading in different directions can be achieved. Attached Figure Description
