Description

Technical Field

[0001] The utility model relates to the technical field of connecting devices, in particular to a connecting device for a tractor and a snow and ice removing machine. Background Art

[0002] In the cold winter in the north, due to the compacted snow and ice formed by snowfall and vehicle rolling, the road cannot be normally passed, and only the tractor can be relied on to pull the snow and ice removing machine to clean the road surface, and the tractor is connected to the snow and ice removing machine through a connecting device.

[0003] The existing connecting device is usually a direct hard connection between the tractor and the snow and ice removing machine without buffering and shock absorption. The vibration generated by the snow and ice removing machine during operation is transmitted to the tractor, which will directly affect the normal operation of the driver, unable to operate normally, reduce the working comfort and affect the working efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a connecting device for a tractor and a snow and ice removing machine, which reduces the vibration of the tractor caused by the operation of the snow and ice removing machine, increases the working comfort of the driver and ensures the normal operation.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A connecting device for a tractor and a snow and ice removing machine, used for connecting the snow and ice removing machine and the tractor, includes a front panel, a rear panel, a first upper support plate, a first lower support plate, a second upper support plate, a second lower support plate, springs and fixed shafts. The front panel and the rear panel are arranged front and rear. The front panel is connected to the tractor, and the rear panel is connected to the snow and ice removing machine. The first upper support plate is arranged at the upper section of the rear end of the front panel, the first lower support plate is arranged at the lower section of the rear end of the front panel, the second upper support plate is arranged at the upper section of the front end of the rear panel, the second lower support plate is arranged at the lower section of the front end of the rear panel. The first upper support plate is located below the second upper support plate, and the first lower support plate is located below the second lower support plate. The two springs are respectively arranged between the left and right ends of the first upper support plate and the second lower support plate. The fixed shafts pass through the first upper support plate, the first lower support plate, the springs, the second upper support plate and the second lower support plate.

[0006] The effect of the above technical solution: By arranging springs between the front panel and the rear panel, it will reduce buffering when the tractor pulls the snow and ice removing machine, achieving the effect of shock absorption, thereby increasing the working comfort of the driver and ensuring normal operation.

[0007] The present utility model is further configured such that the fixed shaft is a pin shaft, and the pin shaft has a clearance fit with the first upper support plate, the first lower support plate, the spring, the second upper support plate, and the second lower support plate, and the length of the pin shaft is greater than the distance between the second upper support plate and the first lower support plate.

[0008] The present utility model is further configured such that a nut is provided at the upper end of the pin shaft, and the nut is located above the second upper support plate.

[0009] By adopting the above technical solution, installing a nut on the pin shaft facilitates the installation and disassembly of the pin shaft, and setting the nut above the second upper support plate can achieve the effect of fastening the front panel and the rear panel.

[0010] The present utility model is further configured to further include an ear plate for connecting the tractor, and the ear plate is provided at the front end of the front panel.

[0011] By adopting the above technical solution, the ear plate can be hinged to the tractor. In this hinged manner, the ear plate can not only effectively disperse the stress generated during the towing process, reduce the direct impact on the connection point, but also enable the connection between the tractor and the ice-breaking and snow-removing machine to adapt to traction forces at different angles.

[0012] The present utility model is further configured to further include a fixing hole for connecting the ice-breaking and snow-removing machine, and the fixing hole is provided at the upper end of the rear panel.

[0013] By adopting the above technical solution, the stability between the rear panel and the ice-breaking and snow-removing machine is enhanced, preventing the ice-breaking and snow-removing machine from falling off during towing. BRIEF DESCRIPTION OF THE DRAWINGS
