Technical Field

[0001] This utility model belongs to the field of coal mine underground water tank cleaning technology, specifically an anti-collision spiral aggregate mixing suction head. Background Technology

[0002] Coal sludge cleaning machines are the main equipment for cleaning underground water tanks, sedimentation ponds, and ditches in coal mines. The mixing suction head in front of the cleaning machine is used to collect coal sludge and transport it to the suction port. Due to the dark and harsh environment underground, the cleaning machine often collides with the tunnel wall during operation, resulting in vehicle damage and threatening the safety of operators.

Detailed Implementation

[0020] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, an anti-collision spiral aggregate mixing suction head includes:

[0022] The main frame 1 has a front protective frame 10 at its upper end. At least one set of anti-collision components 2 is provided at the widest part of the main frame 1. The anti-collision components 2 are used to protect the stirring suction head from collision and provide a signal when the stirring suction head collides with an obstacle. Specifically, a set of anti-collision components 2 can be provided at each end of the front protective frame 10.

[0023] The material collection baffle 3 is installed on the main frame 1. The material collection baffle 3 is provided with a suction port 301 and a filter screen frame 7 is provided at the suction port 301.

[0024] The mixing shaft is installed on the collecting baffle 3. The mixing shaft includes a driven shaft 5 and a spiral shaft 4 symmetrically arranged at both ends of the driven shaft 5. The spiral shaft 4 is provided with spiral blades 401. The spiral shaft 4 is used to spirally mix the material and collect it into the suction port 301. The driven shaft 5 is provided with cleaning teeth 501, which is used to clean the filter screen frame 7 and prevent the filter screen frame 7 from being blocked by debris.

[0025] The hydraulic motor 6 is mounted on the main frame 1. The hydraulic motor 6 drives the driven shaft 5 to rotate through the sprocket 9 and the chain 8. The driven shaft 5 drives the screw shaft 4 to rotate.

[0026] The anti-collision assembly 2 includes a collision head 201 and a proximity switch 203. When the collision head 201 collides with an obstacle, it can slide within the anti-collision sleeve 202. After sliding a certain distance, it contacts the proximity switch 203. The anti-collision assembly 2 also includes a reset device, which is used to control the collision head 201 to return to its initial position when it detaches from the obstacle. The reset device can be a reset spring 204.

[0027] The collision head 201 can slide synchronously within the three anti-collision sleeves 202 to ensure that the collision head 201 slides smoothly when it collides with an obstacle. The three anti-collision sleeves 202 can be arranged in a triangular pattern.

[0028] This utility model is installed at the head of the cleaning machine. The suction port 301 connects to the mud pump inlet on the cleaning machine. The specific working process is as follows: This utility model moves into the mine water tank along with the cleaning machine. The hydraulic motor 6 is started, and the driven shaft 5 and the spiral shaft 4 rotate. The spiral blades 401 stir and push the coal slurry, realizing the spiral stirring and collection of the coal slurry and conveying it to the suction port 301. The mud pump pumps the coal slurry to the designated location. The cleaning machine moves and works simultaneously. When the cleaning machine is performing a left or right turn, if it accidentally hits the side wall, the collision head 201 contacts the proximity switch 203. After sensing the collision, the proximity switch 203 immediately sends a signal to the vehicle's control system. The cleaning machine immediately stops moving in that direction or continues to turn, effectively preventing the cleaning machine from further colliding with the wall and avoiding more serious damage.
