Description

Technical Field

[0001] The utility model relates to the technical field of crusher equipment, in particular to a heat - proof crusher convenient for maintenance. Background Technique

[0002] A crusher is a machine that crushes large - sized solid raw materials into required sizes. According to the size of the material to be crushed or the crushed material, crushers can be classified into coarse crushers, crushers, and ultrafine crushers. With the rapid development of the social economy, the real estate industry has also developed vigorously, resulting in a large amount of construction waste. Construction waste refers to the muck, waste soil, waste materials, surplus mud, and other waste generated during the construction, laying, demolition, or repair of various buildings, structures, pipe networks, etc. In order to process construction waste, a crusher is needed to crush it for recycling, thereby reducing environmental pollution.

[0003] In a construction waste crusher disclosed in the Chinese utility model patent application publication specification CN207238120U, although it is convenient to repair by setting a first connecting plate fixedly connected to the output shaft, fixing piles arranged around the bottom of the first connecting plate, a second connecting plate clamped with the fixing piles, arc - shaped holes symmetrically opened on the left and right sides of the rotating shaft and clamped with the pressing rod, and at the same time, clamping devices arranged on the left and right sides inside the clamping box, springs located inside the clamping devices, and a pressing block fixedly connected to the pressing rod. By pulling the rotating shaft, the pressing rod drives the pressing block to act on the spring, so that it is convenient for the pressing rod to disengage from the arc - shaped hole, disassemble the rotating shaft, and finally facilitate its repair, saving time and effort and effectively improving work efficiency. By setting a rubber ring inside the through - hole at the connection between the clamping box and the rotating shaft, it effectively prevents dust from entering the clamping box through the through - hole. By setting a stop block at the opening of the clamping device, and a rod hole adapted to the pressing rod is opened at the connection between the stop block and the pressing rod, it not only limits the pressing rod but also effectively improves the stability of the pressing rod's movement. However, this device only facilitates the disassembly and repair of the rotating shaft, prevents dust from entering the clamping box, and not only limits the pressing rod to improve stability, but also has problems such as being able to quickly disassemble and repair the equipment after it is damaged, avoiding the equipment being placed too low for maintenance personnel to repair, avoiding the equipment being stuck due to too much material being poured in, resulting in the motor idling overheat and damage, and avoiding the need for another maintenance person to assist in operating the equipment when one part of the crusher is damaged, avoiding dropping and wasting manpower and speeding up the work speed. Therefore, a utility model is proposed to solve the above problems. Content of the Utility Model

[0030] The working principle of this utility model:

[0031] During use, the support hydraulic press 2 drives the support hydraulic rod 3 to expand and contract, causing the crushing shell 4 to move up and down on the support base 1. After the equipment is used for crushing for a long time, the crushing assembly 9 can be quickly removed by rotating the bolt 8 for maintenance. When in use, the crushing motor 902 drives the auger shaft 903 to rotate, so that the added material is crushed by the auger shaft 903. The agitation motor 6 drives the agitator 7 to rotate. When crushing the material, the agitator 7 rotates to dredge the material. After the crushing assembly 9 is damaged, the rotation motor 1302 drives the rotating seat 1303 to rotate, so that the inspection seat 1310 rotates into the crushing shell 4. The rotation hydraulic press 1304 drives the rotation hydraulic rod 1305 to expand and contract, so that the inspection seat 1310 adjusts the distance according to which of the two auger shafts 903 in the crushing assembly 9 is damaged. The rotation motor 1306 drives the rotating seat 1307 to rotate, avoiding the situation that when the rotating seat 1303 rotates, the inspection hydraulic rod 1309 is too high to rotate into the crushing shell 4. The inspection hydraulic press 1308 drives the inspection hydraulic rod 1309 to expand and contract, so that the inspection seat 1310 expands and contracts on the inspection hydraulic rod 1309 to support the auger shaft 903 in the crushing assembly 9. The moving motor 11 drives the moving lead screw 12 to rotate, so that the inspection assembly 13 slides on one side of the crushing shell 4 for support. The inspection assembly 13 supports the auger shaft 903 at different positions. After the crushing assembly 9 of this equipment is damaged, the crushing shell 4 can be lifted and lowered conveniently for maintenance by maintenance personnel, avoiding the situation that the equipment is placed too low, which is inconvenient for equipment maintenance and affects the maintenance speed, and avoiding too much material being poured in, which causes the crushing motor 902 to rotate, the auger shaft 903 to get stuck and unable to rotate, and the crushing motor 902 to idle and overheat, resulting in damage. After the equipment is used for crushing for a long time, the crushing assembly 9 can be quickly removed by rotating the bolt 8 for maintenance. After one of the crushing motor 902 and the bearing 904 is damaged, it is convenient to repair and replace the crushing motor 902 and the bearing 904, avoiding the time-consuming and laborious disassembly of the entire crushing assembly 9 for maintenance, which affects the working speed, and when repairing and replacing the crushing motor 902 and the bearing 904 separately, avoiding the need for another maintenance person to assist in operating the auger shaft 903 to avoid dropping and wasting manpower.
