Description

A shot blasting machine with a shot blasting grit sorting device Technical Field

[0001] This utility model relates to the field of shot blasting and gravel sorting technology, specifically to a shot blasting cleaning machine's shot blasting and gravel sorting device. Background Technology

[0002] Shot blasting machines utilize a high-speed rotating impeller to propel shot onto the workpiece surface. The impact of the shot removes impurities such as oil, rust, oxide layers, and welding slag, while simultaneously enhancing surface properties and improving the fatigue strength, wear resistance, and corrosion resistance of the parts. The shot blasting grit separation device is the core component of the shot blasting machine. Its core function is to accurately separate the shot from broken grit, oxide scale, and other impurities, ensuring the quality of shot recycling.

[0003] In traditional shot blasting machines, the filter plates of the shot blasting sand and gravel separation device are prone to clogging after long-term sand and gravel separation, which affects the subsequent separation effect. In addition, the feeding speed is not well controlled, which may lead to incomplete separation or equipment overload. Therefore, a shot blasting sand and gravel separation device for shot blasting machines is proposed. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems of filter plate clogging and poor feed rate control in traditional shot blasting machine shot blasting sand and gravel sorting devices after long-term sand and gravel sorting. This utility model provides a shot blasting sand and gravel sorting device for shot blasting machines.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A shot blasting machine's shot blasting grit sorting device includes a sorting box, which is a hollow rectangular box with a perforated top. A filter plate is fixedly installed inside the sorting box, with several filter holes arranged in a rectangular array on its top for filtering large particles. A filter plate is also fixedly installed inside the sorting box, with corresponding filter holes for filtering small particles on its top. Two strip plates are positioned between the filter plates, with hydraulic rods fixedly installed on the opposite sides of each strip plate. Each hydraulic rod has a long rod fixedly connected to its output end, and several equidistant top rods are fixedly installed on the opposite side of each long rod. The sorting box contains a transmission assembly for driving the two strip plates in linear reciprocating motion, a material control assembly for controlling material feeding, and a material guide assembly for guiding material feeding on the right wall of the sorting box.

[0007] Furthermore, the transmission assembly includes mounting blocks. Two mounting blocks are fixedly installed inside the sorting box, and a lead screw is movably installed between the two mounting blocks. A moving block is threaded onto the lead screw, and each strip plate is fixedly connected to the moving block. A limit rod is fixedly installed between the two mounting blocks, and an L-shaped rod is fixedly installed on the left wall of the sorting box. A servo motor for driving the lead screw to rotate is fixedly installed inside the L-shaped rod.

[0008] Furthermore, the material control assembly includes a first guide plate, a second guide plate fixedly installed inside the sorting box, the first guide plate being inclined downwards from right to left, and the second guide plate being inclined downwards from left to right.

[0009] Furthermore, the material control assembly also includes a rotating shaft, which is movably installed inside the sorting box. An actuator motor for driving the rotating shaft to rotate is fixedly installed on the rear wall of the sorting box. Four evenly distributed material distribution plates are fixedly installed on the side wall of the rotating shaft, and an arc-shaped plate is fixedly installed inside the sorting box.

[0010] Furthermore, the material guiding assembly includes a guide channel. Two guide channels are fixedly installed on the right wall of the sorting box. The front side of the upper guide channel is hollowed out, and the rear side of the lower guide channel is hollowed out. Each guide channel has an inlet on the side near the sorting box, and the right wall of the sorting box has an outlet corresponding to the two guide channels.

[0011] Furthermore, the bottom surface of the upper guide channel is inclined downward from back to front, and the bottom surface of the lower guide channel is inclined downward from front to right.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this invention, when shot and gravel enter the sorting box through the top opening, the material control component first controls the feeding amount and speed. As the material continues to fall onto the surface of filter plate one after passing through the material control component, large particles will be unable to pass through filter hole one and will roll down on the surface of filter plate one. Shot and small particles will pass through filter hole one and fall onto the surface of filter plate two. At this time, shot will be unable to pass through filter hole two and will roll down on the surface of filter plate two. Small particles will pass through filter hole two and be discharged from the funnel. The material guiding component can guide the large particles separately. When granular impurities and shot are discharged, if filter holes one and two become clogged due to long-term sorting, the transmission assembly is activated when sorting is not required. This drives the strip plate, hydraulic rod, long rod, and top rod to reciprocate intermittently at a preset distance. Each time the transmission assembly stops, the two hydraulic rods extend, and each hydraulic rod drives the corresponding long rod and top rod to move synchronously. The top rod located above can be inserted into the interior of filter hole one, and the top rod located below can be inserted into the interior of filter hole two, thereby clearing the blockages inside filter holes one and two.

[0024] As shown in Figures 1 to 5, a shot blasting sand and gravel sorting device for a shot blasting machine includes a sorting box 1, which is a hollow rectangular box with a perforated top. A filter plate 3 is fixedly installed inside the sorting box 1. The top of the filter plate 3 has several filter holes 4 arranged in a rectangular array for filtering large particles of impurities. A second filter plate 5 is also fixedly installed inside the sorting box 1. The top of the second filter plate 5 has filter holes 6 corresponding to each filter hole 4 for filtering small particles of impurities. Two strip plates 7 are arranged between the filter plate 3 and the second filter plate 5. Hydraulic rods 8 are fixedly installed on the opposite sides of the two strip plates 7. A long rod 9 is fixedly connected to the output end of each hydraulic rod 8. Several equidistantly distributed top rods 10 are fixedly installed on the opposite side of each long rod 9. The sorting box 1 contains a transmission assembly 11 for driving the two strip plates 7 in linear reciprocating motion. The sorting box 1 also contains a material control assembly 12 for controlling material feeding. A material guide assembly 13 is provided on the right wall of the sorting box 1 to guide the material feeding. It should be noted that when shot blasting and gravel pass through the top perforation of the sorting box 1... When the material enters the sorting process, the material control component 12 first controls the feeding amount and speed. As the material continues to fall through the material control component 12 onto the surface of filter plate 3, large particles will be unable to pass through filter holes 4 and will roll downwards on the surface of filter plate 3. Shots and small particles will pass through filter holes 4 and fall onto the surface of filter plate 5. At this point, shot will be unable to pass through filter holes 6 and will roll downwards on the surface of filter plate 5. Small particles will pass through filter holes 6 and be discharged from the funnel 2. The material guiding component 13 can guide the large particles and shot out of the hopper 2 respectively. If filter holes 4 and filter... Due to long-term clogging during sorting, hole 6 becomes clogged. When sorting is not required, the transmission assembly 11 is activated to drive the strip plate 7, hydraulic rod 8, long rod 9, and top rod 10 to reciprocate intermittently at a preset distance. Each time the transmission assembly 11 stops, the two hydraulic rods 8 extend, and each hydraulic rod 8 drives the corresponding long rod 9 and top rod 10 to move synchronously. The top rod 10 located above can be inserted into the interior of filter hole 4, and the top rod 10 located below can be inserted into the interior of filter hole 6, thereby clearing the blockage inside filter hole 4 and filter hole 6.

[0025] The transmission assembly 11 includes mounting blocks 1101. Two mounting blocks 1101 are fixedly installed inside the sorting box 1. A lead screw 1102 is movably installed between the two mounting blocks 1101. A moving block 1103 is threaded onto the lead screw 1102. Each strip plate 7 is fixedly connected to the moving block 1103. A limit rod 1104 is fixedly installed between the two mounting blocks 1101. An L-shaped rod 1105 is fixedly installed on the left wall of the sorting box 1. A servo motor 1106 for driving the lead screw 1102 to rotate is fixedly installed inside the L-shaped rod 1105. It should be noted that after the servo motor 1106 is started, it can drive the lead screw 1102 to rotate reciprocally. At this time, the moving block 1103 can move linearly back and forth. By controlling the rotation speed, angle and frequency of the output end of the servo motor 1106, the moving block 1103 can be made to intermittently move linearly back and forth at a preset distance. The movement of the moving block 1103 will drive the two strip plates 7 to move synchronously.

[0026] The material control assembly 12 includes a first guide plate 1201, which is fixedly installed inside the sorting box 1, and a second guide plate 1202 is fixedly installed inside the sorting box 1. The first guide plate 1201 is inclined downward from right to left, and the second guide plate 1202 is inclined downward from left to right. It should be noted that both the first guide plate 1201 and the second guide plate 1202 can guide the material to converge, so as to control the amount of material discharged.

[0027] The material control assembly 12 also includes a rotating shaft 1203. The rotating shaft 1203 is movably installed inside the sorting box 1. An actuator motor 1204 for driving the rotating shaft 1203 to rotate is fixedly installed on the rear wall of the sorting box 1. Four evenly distributed material distribution plates 1205 are fixedly installed on the side wall of the rotating shaft 1203. An arc-shaped plate 1206 is fixedly installed inside the sorting box 1. It should be noted that after the actuator motor 1204 is started, it can drive the rotating shaft 1203 to rotate intermittently, rotating 90 degrees each time. When the rotating shaft 1203 rotates, it will drive the material distribution plates 1205 to rotate synchronously. After the rotating shaft 1203 rotates 90 degrees, some of the material accumulated on the surface of the guide plate 1201 can be discharged.

[0028] The material guiding assembly 13 includes a guide channel 1301. Two guide channels 1301 are fixedly installed on the right wall of the sorting box 1. The front side of the upper guide channel 1301 is hollowed out, and the rear side of the lower guide channel 1301 is hollowed out. Each guide channel 1301 has a feed inlet 1302 on the side near the sorting box 1. The right wall of the sorting box 1 has a discharge outlet 1303 corresponding to the two guide channels 1301. It should be noted that when large particles and bullets roll down, they enter the interior of the two guide channels 1301 respectively. The large particles and bullets inside the guide channels 1301 are discharged from the discharge end respectively.

[0029] The bottom surface of the upper guide channel 1301 is inclined downward from back to front, and the bottom surface of the lower guide channel 1301 is inclined downward from front to right. It should be noted that, because the bottom surface of the guide channel 1301 is inclined, large particles of impurities and bullets inside the guide channel 1301 roll down to the lower part and are discharged from the corresponding discharge end.

[0030] In summary:

[0031] When shot and gravel enter the sorting box 1 through the top perforation, the material control component 12 first controls the feeding amount and speed. As the material continues to fall to the surface of filter plate 3 after passing through the material control component 12, large particles will not be able to pass through filter hole 4 and will roll down on the surface of filter plate 3. Shot and small particles will pass through filter hole 4 and fall to the surface of filter plate 5. At this time, shot will not be able to pass through filter hole 6 and will roll down on the surface of filter plate 5. Small particles will pass through filter hole 6 and be discharged from funnel 2. The material guiding component 13 can guide the large particles and shot to be discharged separately. If filter holes 4 and 6 become clogged due to long-term sorting, and sorting is not required, the transmission assembly 11 is activated to drive the strip plate 7, hydraulic rod 8, long rod 9, and top rod 10 to reciprocate intermittently at a preset distance. Each time the transmission assembly 11 stops, the two hydraulic rods 8 extend, and each hydraulic rod 8 drives the corresponding long rod 9 and top rod 10 to move synchronously. The top rod 10 located above can be inserted into the interior of filter hole 4, and the top rod 10 located below can be inserted into the interior of filter hole 6, thereby clearing the blockage inside filter holes 4 and 6.
