Abstract
The utility model discloses an auger overload protection device, which relates to the technical field of snow removing equipment and comprises an auger transfer case, an auger frame and blades arranged on the auger frame; the output shaft of the auger transfer case is connected with a connecting flange, an output flange is arranged between the auger transfer case and the auger frame, the connecting flange is connected with one end of the output flange through a shearing bolt, the other end of the output flange is connected with the auger frame, and the other end of the auger frame is connected with a connecting bearing; a gap is arranged at the joint of the shearing bolt and the output flange; the clearance is formed by the convex spigot of the connecting flange and the concave spigot of the output flange or by the convex spigot of the connecting flange and the concave spigot of the output flange, and the depth of the convex spigot is larger than that of the concave spigot. The width d of the gap is more than 0.8mm and less than 1 mm. The utility model discloses can solve and cut the bolt fracture when the auger transships, because of the fracture is stung on output flange and flange, cause to be difficult to change the problem of cutting the bolt.
Description
Technical Field
The utility model belongs to the technical field of the snow removing equipment manufacture technique and specifically relates to a protection device for solving when throwing snow car auger transships the bolt of cutting on flange and the output flange is cut off the back, and the bolt is comparatively difficult to cut off in the change.
Background
During snow removal of the snow throwing vehicle, if the auger blade meets an obstacle with large resistance during snow twisting, overload is easily caused. In order to prevent the auger transfer case which drives the auger to rotate from being damaged due to sudden overlarge resistance when the auger of the snow throwing vehicle is overloaded, a protective device which mainly comprises a shearing bolt is generally designed. If application number is 201621387471.3, the notice number of authorizing is CN206308667U, the utility model discloses a utility model patent of "snow throwing car auger overload protection device", this kind cuts bolt protection device, and although can solve auger transfer case output shaft effectively and damage the transfer case problem too greatly when rotating, nevertheless because of cutting bolted connection's output flange and flange, be the laminating after the assembly is accomplished. When the shearing bolt is cut off due to overlarge resistance, the fracture can appear on the binding surface of the output flange and the connecting flange, and the fracture surface of the shearing bolt can be occluded and clamped on the binding surface of the output flange and the connecting flange. This has the problem that it is difficult for the user to replace the shear bolt with a new one.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an auger overload protection device is provided, it can solve when snow throwing vehicle auger transships cutting off the bolt on flange and the output flange and cut off the back, stings the problem of dying to be difficult to change on output flange or flange.
In order to solve the above problem, the technical scheme of the utility model is that: this kind of auger overload protection device includes auger transfer case and auger frame and sets up blade on the auger frame, the output shaft and the flange connection of auger transfer case with be provided with output flange between the auger frame, flange through cut the bolt with output flange's one end is connected, output flange's the other end with the one end of auger frame is connected, the other end of auger frame is connected with the connecting bearing who establishes on throwing the head base, flange with output flange is provided with the clearance cutting bolted connection department.
In the above technical solution, a more specific solution is: the gap is formed by the convex spigot of the connecting flange and the concave spigot of the output flange or formed by the convex spigot of the connecting flange and the concave spigot of the output flange, and the depth of the convex spigot is greater than that of the concave spigot.
Further: the width of the gap is d, and d is more than 0.8mm and less than 1 mm.
Due to the adoption of the technical scheme, the utility model discloses following beneficial effect has:
the utility model discloses cut the bolt fracture when the auger transships, because bolt fracture department is gapped, the fracture can not sting on output flange and flange, has solved effectively and has cut the bolt and has stung the problem that is difficult to change on output flange and flange because of the fracture.

Detailed Description
The invention will be further described with reference to the following figures and examples:
the auger overload protection device shown in the figures 1 to 4 comprises an output flange 4, a shearing bolt 3 and a connecting flange 2, wherein the connecting flange 2 is connected with an output shaft of an auger transfer case 1, the connecting flange 2 is connected with the output flange 4 by tightening the shearing bolt 3, a gap with the width of d is formed between a convex spigot of the connecting flange 2 and a concave spigot of the output flange 4 or between a concave spigot of the connecting flange 2 and a convex spigot of the output flange 4 at the penetrating position of the shearing bolt, and the depth of the convex spigot is larger than that of the concave spigot, so that after the assembly is finished, the width of the gap guaranteed to be left between the connecting flange 2 and the output flange 4 is d, and d is more than 0.8mm and less than 1 mm;
when the output shaft of the transfer case 1 rotates, the connecting flange 2 and the output flange 4 are driven to rotate together. The other end of the output flange 4 is connected with the auger frame 5, the blade 6 is connected with the auger frame 5, the other end of the auger frame 5 is connected with the connecting bearing 7, the blade 6 and the auger frame 5 are driven by the output flange 4 to realize rotation work, when the auger frame 5 works and rotates, the resistance received is overlarge, the shearing bolts 3 on the connecting flange 2 and the output flange 4 can be sheared due to overlarge shearing force received, the fracture of the shearing bolt 3 can be in the gap between the connecting flange 2 and the output flange 4, because of the existence of the gap d, the irregular fracture section of the shearing bolt 3 can not be occluded and clamped on the surfaces of the output flange 4 and the connecting flange 2, the shearing bolt 3 can be easily detached, and the replacement of the shearing bolt 3 is very convenient.
