Abstract
Description
Technical Field
[0001] The utility model relates to the field of wood grabbers, in particular to a fixed wood grabber. Background Art
[0002] A wood grabber, as the name implies, is a machine for grabbing wood, and is generally evolved from a hydraulic excavator. The biggest difference between a wood grabber and an ordinary excavator is the difference in the front-end working device, that is, the different working purposes: the arms and legs of an ordinary excavator are generally shorter, with a bucket at the front end, and their main function is to dig and load; the arms and legs of a wood grabber, commonly known as a "grabbing arm", are generally longer, and their shape and structure are also different from those of an ordinary excavator. Their front end is a wood grabber, and their main function is to load, unload and carry wood, timber, reeds, straw and various strip materials; currently, when a fixed wood grabber is operating to grab wood, as the operating time increases, the jaws are prone to wear, which affects the clamping of wood.
[0003] Therefore, a fixed wood grabber is proposed to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide a fixed wood grabber in order to solve the above problems, thereby improving the problem that when the fixed wood grabber is operating, the clamping claws are easily worn out as the operation time increases, which affects the clamping of the wood.
[0005] The utility model achieves the above-mentioned purpose through the following technical scheme, a fixed wood grabber, comprising: a main body, both sides of which are hinged with clamping jaws; a clamping mechanism, which is installed on one side of the clamping jaw and can prevent the clamping jaw from being worn; wherein the clamping mechanism comprises two fixed shells fixedly installed on the inner wall of the clamping jaw, both sides of the inner cavity of the fixed shell are slidably installed with sliding blocks, a first spring is fixedly installed between the two sliding blocks, a buffer is arranged on the inner side of the fixed shell, and an elastic member is fixedly installed between the clamping jaw and the fixed shell.
[0006] Preferably, the buffer member comprises a push rod hinged to the bottom of the sliding block, one end of the push rod away from the sliding block is hinged to a mounting plate, and a clamping plate is installed on one side of the mounting plate.
[0007] Preferably, a plurality of second springs are fixedly mounted between the fixed shell and the mounting plate, and the second springs are installed obliquely.
[0008] Preferably, the elastic member includes two fixing plates fixedly mounted on the inner side wall of the clamp, a mounting seat is fixedly mounted on one side of the fixing plate adjacent to the mounting plate, a sliding rod is fixedly mounted on one side adjacent to the two mounting seats, a moving block is slidably mounted on the surface of the sliding rod, and a scissor rod is hinged on the inner side wall of the moving block.
[0009] Preferably, third springs are sleeved on both sides of the surface of the sliding rod, and one end of the third spring is fixedly connected to the moving block.
[0010] Preferably, screws are installed penetratingly around the surface of the mounting plate, and the mounting plate is fixedly connected to the clamping plate by screws.
[0011] Preferably, an anti-skid pad is installed on the side of the clamping jaw away from the main body, and the material of the anti-skid pad is a rubber component.
[0012] The beneficial effects of the utility model are:
[0013] 1. By adding a clamping mechanism to the inner side of the clamping jaw, the wear of the clamping jaw during long-term use can be avoided. The split design between the clamping plate and the mounting plate can be used to replace the clamping plate in time when the clamping plate is worn. This changes the traditional clamping jaw, which requires the entire main body to be disassembled and assembled when it is worn. This avoids the wear of the clamping jaw and facilitates the replacement of the clamping plate. At the same time, the cost of the clamping plate is lower than that of the clamping jaw, so as to reduce the cost.
[0014] 2. When the clamping mechanism is used to clamp the wood, the clamping plate is in contact with the wood in advance, and as the wood grabber continues to clamp, the clamping plate drives the push rod and the sliding block to slide inside the fixed shell, and the elasticity of the first spring and the second spring is used to buffer the clamping plate, thereby buffering the wood when clamping it and avoiding the situation where the clamping mechanism directly contacts the rigid body of the main body and causes damage to the wood.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] When implementing: Figure 1-4 As shown, a fixed wood grabber comprises:
[0022] A main body 10, with clamping claws 11 hinged on both sides of the main body 10;
[0023] The clamping mechanism 20 is installed on one side of the clamping jaw 11 and can prevent the clamping jaw 11 from being worn; an anti-skid pad is installed on the side of the clamping jaw 11 away from the main body 10, and the material of the anti-skid pad is a rubber component.
[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the clamping mechanism 20 includes two fixed shells 21 fixedly mounted on the inner side walls of the clamping jaws 11, sliding blocks 22 are slidably mounted on both sides of the inner cavity of the fixed shell 21, a first spring 23 is fixedly mounted between the two sliding blocks 22, a buffer member 24 is arranged on the inner side of the fixed shell 21, and an elastic member 25 is fixedly mounted between the clamping jaws 11 and the fixed shell 21; the buffer member 24 includes a push rod 241 hinged to the bottom of the sliding block 22, a mounting plate 242 is hinged at one end of the push rod 241 away from the sliding block 22, and a clamping plate 243 is mounted on one side of the mounting plate 242; a plurality of second springs 244 are fixedly mounted between the fixed shell 21 and the mounting plate 242, and the second springs 244 are obliquely mounted; screws are installed through the four sides of the surface of the mounting plate 242, and the mounting plate 242 and the clamping plate 243 are fixedly connected by screws;
[0025] In this embodiment, by adding a clamping mechanism 20 to the inner side of the clamping jaw 11, it is possible to prevent the clamping jaw 11 from being worn during long-term use. By utilizing the split design between the clamping plate 243 and the mounting plate 242, the clamping plate 243 can be replaced in time when the clamping plate 243 is worn, thereby changing the traditional clamping jaw 11 from requiring the entire main body 10 to be disassembled and assembled when it is worn.
[0026] like Figure 1 , Figure 2 and Figure 4As shown, the elastic member 25 includes two fixing plates 251 fixedly mounted on the inner side wall of the clamping jaw 11, a mounting seat 252 is fixedly mounted on one side of the fixing plate 251 adjacent to the mounting plate 242, a sliding rod 253 is fixedly mounted on one side of the two mounting seats 252 adjacent to each other, a moving block 254 is slidably mounted on the surface of the sliding rod 253, and a scissor rod 255 is hingedly connected to the inner side wall of the moving block 254; a third spring 256 is sleeved on both sides of the surface of the sliding rod 253, and one end of the third spring 256 is fixedly connected to the moving block 254;
[0027] In this embodiment, when the mounting plate 242 is subjected to force, the mounting plate 242 drives the mounting seat 252 to move inward, and the mounting plate 242 is further buffered by the elasticity between the scissor rod 255 and the third spring 256 .
[0028] When the utility model clamps the wood, the clamping plate 243 contacts the wood in advance, and as the wood grabber continues to clamp, the clamping plate 243 drives the push rod 241 and the sliding block 22 to slide inside the fixed shell 21, and uses the elasticity of the first spring 23 and the second spring 244 to buffer the clamping plate 243, and while the mounting plate 242 is subjected to force, the mounting plate 242 drives the mounting seat 252 to move inward, and the mounting plate 242 is further buffered by the elasticity between the scissor rod 255 and the third spring 256, so that the jaws 11 can avoid over-clamping when driving the clamping mechanism 20 to clamp the wood, resulting in damage to the wood.
[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
