Description

Technical Field

[0001] The utility model relates to the technical field of tractor manufacturing, in particular to a tractor welding bracket. Background Art

[0002] A tractor is a self-propelled power machine used to pull and drive work machinery to complete various mobile operations. It can also be used as a fixed working power. It is composed of engine, transmission, travel, steering, hydraulic suspension, power output, electrical instruments, driving control and traction systems or devices. The engine power is transmitted to the drive wheels by the transmission system to make the tractor move. In real life, the most common ones are those that use rubber belts as the medium for power transmission. Tractors are divided into agricultural, industrial and special-purpose tractors according to their functions and uses; they are divided into wheeled, crawler, boat-shaped tractors and self-propelled chassis according to the structural type. The tractor front bracket is one of the components of the tractor.

[0003] Relevant technicians engaged in tractor manufacturing have found in their work that the accumulated water at the bottom of the cast iron tractor bracket cannot be effectively discharged. The accumulated water in the low-lying area at the bottom of the bracket will cause the bracket and internal mechanical parts to rust, resulting in a reduction in the life of the machinery. For this reason, we propose a tractor welding bracket. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the accumulated water at the bottom of the cast iron tractor bracket cannot be effectively discharged, and the accumulated water in the low-lying area at the bottom of the bracket will cause the bracket and internal mechanical parts to rust, resulting in a reduction in the life of the machinery. The utility model provides a tractor welding bracket.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The utility model arranges the bottom of the bracket body to be low in the front and high in the back, so that the accumulated water in the bracket body is gathered forward. Through the arranged water pumping seat and air supply seat, the air supply seat can alternately pump air and inflate air into the water pumping seat through the air pipe. When the air supply seat pumps air, a negative pressure is formed in the water pumping seat, so that the water pumping seat sucks gas from the water inlet check valve to balance the pressure. At the same time, the accumulated water at the bottom of the bracket body can be pumped into the water pumping seat through the water inlet check valve. When the air supply seat is inflated, the pressure in the water pumping seat increases, and the accumulated water and gas sucked into the water pumping seat can be pressed out through the drainage check valve, so that the accumulated water at the bottom of the bracket body is actively pumped out and discharged, thereby avoiding rusting of the bracket body and mechanical parts in the bracket body and improving the service life of the bracket body and mechanical parts.

An elastic pressure rod is provided, and the middle part of the elastic pressure rod is hinged and rotated through a fixed hinge seat. The configuration block on the rear side of the elastic pressure rod can swing up and down under the influence of the mechanical vibration of the tractor and the fluctuation of the road surface when the tractor is traveling. When the configuration block moves up, the front side of the elastic pressure rod moves down, and the airtight piston is pushed down by the return elastic force of the return spring, and air is pumped in the water pumping seat through the air supply pipe. When the configuration block moves down, the front side of the fixed hinge seat moves up, pushing the compression push rod to move up, thereby squeezing the airtight piston and the return spring, and inflating the water pumping seat through the air supply pipe. The structure is simple and no external power is required.

[0016] 3. The utility model provides a contact rubber pad and an embedded bolt, so that the contact rubber pad can expand in contact with the front end of the elastic pressure rod, thereby reducing collision noise and increasing the service life of the compression push rod. The threaded connection of the embedded bolt can facilitate the maintenance and replacement of the contact rubber pad. BRIEF DESCRIPTION OF THE DRAWINGS
