Description

Technical Field

[0001] The utility model relates to the height adjustment of a grinding head of a belt grinder, in particular to a height adjustment device for a grinding head of a belt grinder. Background Art

[0002] The existing height adjustment device for the grinding head of a belt grinder includes a cylinder, a cylinder body of the cylinder is hinged on a frame, a piston rod is fixedly connected to an adjuster, and the adjuster is connected to the grinding head through a Y-type joint. When rotating, it is necessary to manually rotate a handle on the adjuster to adjust the height. Manual adjustment is time-consuming and laborious. Uneven adjustment force may easily lead to damage to the screw rod of the adjuster. In addition, since the screw rod is exposed, dust often accumulates on the surface of the screw rod, which may easily cause wear and thread slippage. Summary of the invention

[0003] The utility model aims at the shortcomings of the prior art and provides a belt grinder head height adjustment device, which adopts a worm lift and a cylinder to adjust the grinding head height, thereby realizing automatic adjustment, saving manpower and avoiding the problems of wear, thread slippage and screw rod damage that occur in manually adjusted regulators.

[0004] The technical solution disclosed in the utility model is as follows: a height adjustment device for a belt grinding head, comprising:

[0005] Fixed base;

[0006] A worm gear lift, fixedly mounted on a fixed base;

[0007] The cylinder comprises a cylinder body and a piston rod. The lower end of the cylinder body is hinged on the lifting screw of the worm lifting mechanism, and the piston rod is hinged on the grinding head.

[0008] On the basis of the above solution, preferably, the fixed base includes a fixed plate and a support rod fixedly installed at the bottom of the fixed plate.

[0009] Based on the above solution, preferably, the support rod and the fixing plate are fixed by welding.

[0010] On the basis of the above solution, as a preference, the motor is fixed on a fixed plate, and the output shaft of the motor is fixedly connected to the input shaft of the worm gear lift.

[0011] On the basis of the above solution, preferably, the piston rod is hinged to the grinding head via a Y-type joint.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The grinding head height is adjusted by cooperating with a worm lift and a cylinder to realize automatic adjustment, save manpower, and avoid the problems of wear, thread slippage, and screw damage that occur in manually adjusted regulators. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0015] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0016] like Figure 1 As shown, a belt grinding head height adjustment device comprises:

[0017] Fixed base 1;

[0018] A worm elevator 2 is fixedly mounted on a fixed base;

[0019] The cylinder 3 comprises a cylinder body 31 and a piston rod 32. The lower end of the cylinder body is hinged to the lifting screw of the worm lifting mechanism, and the piston rod is hinged to the grinding head.

[0020] The fixed base includes a fixed plate 11 and a support rod 12 fixedly installed at the bottom of the fixed plate.

[0021] The support rod and the fixing plate are fixed by welding.

[0022] The motor 4 is fixed on the fixed plate, and the output shaft of the motor is fixedly connected to the input shaft of the worm gear lift.

[0023] The piston rod is hinged to the grinding head via a Y-type joint 5.

[0024] In this solution, the support rod of the fixed base is fixed on the bearing surface of the belt mill and is not directly installed on the frame of the belt mill.

[0025] It should be noted that the above embodiments can be freely combined as needed. The above is only a preferred implementation of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
