Description

A type of salt field active slag harrow Technical Field

[0001] This invention relates to the field of salt field tools, specifically to a live salt field rake. Background Technology

[0002] A slag rake is a specialized salt-raking mechanism used for slag removal in salt fields. It effectively breaks up and disperses the salt surface. During sea salt production, to improve crystallization efficiency, a slag rake is used to break up large salt crystals in the salt pond; this process is called slag removal.

[0003] Currently, the salt pan slag harrows use ordinary annular harrow teeth, which can avoid damaging the salt pond slabs. However, because the wire used for the annular harrow teeth has a circular cross-section, it is not easy to break up large salt crystals during slag removal, resulting in very low slag removal efficiency. In addition, the plastic sheeting ropes inside the salt ponds can easily get tangled on the slag harrows during the slag removal process. Therefore, it is necessary to have a feature that allows for automatic rope unwinding during slag removal.

[0004] Therefore, a live salt field rake is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a salt field active slag harrow in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0007] A salt pan slag harrow includes two harrow bodies, with a reinforcing rib fixedly connected between them. A rotating shaft is rotatably connected to the top of the inner wall of each harrow body, and a mounting box is fixedly connected to the bottom of the rotating shaft. A harrow tooth assembly is disposed below the mounting box. A locking component for limiting the position of the harrow tooth assembly is disposed on the surface of the mounting box. An angle adjustment component for adjusting the orientation of the harrow tooth assembly is also disposed on the surface of the harrow body. A rope retraction frame is fixedly connected between the two harrow bodies. A sensor for sensing whether the rope retraction frame is in contact with the plastic sheeting retraction rope is disposed on its front side. The harrow tooth assembly includes annular harrow teeth, one side of which is fixedly connected to a prismatic sharp corner. A smooth portion is disposed at the bottom of the annular harrow teeth. The locking component includes a bidirectional screw rod, which is rotatably connected to the inner wall of the mounting box, and one end of the bidirectional screw rod penetrates one side wall of the mounting box and extends... Extending to the outside of the mounting box, one end of the bidirectional lead screw is fixedly connected to a first knob. A clamping block is threaded onto the surface of the bidirectional lead screw. A sliding groove is provided on the inner wall of the mounting box, and the inner wall of the sliding groove is slidably connected to the surface of the clamping block. A connecting block is movably inserted into the bottom of the mounting box, and the connecting block is fixedly connected to the top of the annular rake teeth. A groove adapted to the end of the clamping block is provided on the surface of the connecting block, and the inner wall of the groove is movably inserted into the end of the clamping block. The angle adjustment component includes a mounting plate, and the angle adjustment component of the mounting plate includes a mounting plate, and the mounting plate is fixedly connected to the middle of the inner wall of the rake body. Worms are rotatably connected to the left and right sides of the mounting plate, and the ends of the two worms penetrate the side wall of the rake body and extend to the outside of the rake body. A second knob is fixedly connected to the end of the worm. A worm wheel is fixedly sleeved on the surface of the rotating shaft, and the worm wheel meshes with the worm.

[0008] Furthermore, the number of rake tooth assemblies is two sets, and the two sets of rake tooth assemblies are oriented in opposite directions.

[0009] Furthermore, the sensor is a contact switch, and the sensor is electrically connected to the robotic arm of the traction device.

[0010] Furthermore, the cross-sectional projection of the rope retraction frame covers the rake tooth assembly.

[0011] Furthermore, the surface of the rope-removing frame is coated with polytetrafluoroethylene wear-resistant lubricating material, the rake body is made of stainless steel, and the rake tooth assembly is made of supercooled austenitic carbon steel or alloy steel.

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

[0013] 1. This invention uses a traction device to move the entire movable rake, and utilizes the rake tooth assembly to contact large salt crystals in the salt field. The rake tooth assembly crushes the salt crystals. The angle adjustment component can control the rotation of the shaft and the mounting box, thereby driving the rake tooth assembly to rotate. This changes the angle between the rake tooth assembly and the moving direction of the movable rake, thus adjusting the crushing effect on the salt blocks. This allows it to adapt to different crushing needs and ensure crushing efficiency.

[0014] 2. When the rake tooth assembly wears out, the locking component can be used to release the limit on the rake tooth assembly, allowing for quick disassembly and replacement with a new rake tooth assembly. This ensures the continuous crushing effect of the live slag rake and further guarantees crushing efficiency.

[0015] 3. When the live slag rake is moving, the sensor comes into contact with the plastic tarpaulin's take-up and release rope. The sensor then sends feedback to the operator, who can control the robotic arm of the traction device to lift the live slag rake so that it passes over the rope surface, thus preventing the plastic tarpaulin's take-up and release rope from getting tangled with the live slag rake during operation.

Therefore, they should not be construed as limiting the present invention.

[0027] As shown in Figures 1 to 5, a type of live salt field rake includes two rake bodies 1. A reinforcing rib 2 is fixedly connected between the two rake bodies 1. A rotating shaft 4 is rotatably connected to the top of the inner wall of each rake body 1. A mounting box 5 is fixedly connected to the bottom of the rotating shaft 4. A rake tooth assembly 3 is located below the mounting box 5. A locking component 6 for limiting the position of the rake tooth assembly 3 is provided on the surface of the mounting box 5. An angle adjustment component 7 for adjusting the orientation of the rake tooth assembly 3 is also provided on the surface of the rake body 1. A rope retraction frame 8 is fixedly connected between the two rake bodies 1. A sensor 9 for sensing whether the rope retraction frame 8 is in contact with the plastic sheeting retraction rope is provided on its front side. More specifically, the entire live salt field rake is moved by pulling a traction device, utilizing... The rake tooth assembly 3 comes into contact with large salt crystals in the salt field, crushing the salt crystals. The angle adjustment assembly 7 controls the rotation of the shaft 4 and the mounting box 5, thereby causing the rake tooth assembly 3 to rotate. This changes the angle between the rake tooth assembly 3 and the moving direction of the live rake, thus adjusting the crushing effect on the salt blocks. When the rake tooth assembly 3 wears out, the locking assembly 6 can be used to release the limit on the rake tooth assembly 3, allowing for quick disassembly and replacement with a new rake tooth assembly 3. During the movement of the live rake, the sensor 9 comes into contact with the plastic tarpaulin reel rope. The sensor 9 provides feedback to the operator to prevent the plastic tarpaulin reel rope from becoming entangled with the live rake.

[0028] As shown in Figure 3, the rake tooth assembly 3 includes annular rake teeth 301. A prismatic sharp corner 302 is fixedly connected to one side of the annular rake teeth 301. A smooth part 303 is provided at the bottom of the annular rake teeth 301. It should be noted that the prismatic sharp corner 302 contacts the large salt crystals in the salt pond and uses the sharp edge of the prismatic sharp corner 302 to break the salt crystals. The smooth part 303 has a planar structure, which can prevent damage to the salt pond plate during the sliding process.

[0029] As shown in Figures 3 and 4, the locking assembly 6 includes a bidirectional lead screw 601, which is rotatably connected to the inner wall of the mounting box 5. One end of the bidirectional lead screw 601 passes through one side wall of the mounting box 5 and extends to the outside of the mounting box 5. A first knob 602 is fixedly connected to one end of the bidirectional lead screw 601. A locking block 603 is threaded onto the surface of the bidirectional lead screw 601. A groove 604 is provided on the inner wall of the mounting box 5, and the inner wall of the groove 604 is slidably connected to the surface of the locking block 603. A connecting block 605 is movably inserted into the bottom of the mounting box 5, and the connecting block 605 is connected to the annular rake teeth. The top of 301 is fixedly connected, and the surface of the connecting block 605 is provided with a groove that matches the end of the clamping block 603. The inner wall of the groove is movably inserted into the end of the clamping block 603. More specifically, by rotating the first knob 602, the bidirectional lead screw 601 is driven to rotate. Under the action of the thread, the clamping block 603 is driven to slide along the inner wall of the slide groove 604, so that the end of the clamping block 603 is disengaged from the inner wall of the groove on the surface of the connecting block 605. By pulling the connecting block 605 down, the rake tooth assembly 3 can be disassembled, so as to facilitate the quick replacement of the worn rake tooth assembly 3.

[0030] As shown in Figure 2, the angle adjustment assembly 7 includes a mounting plate 701, and the mounting plate 701 is fixedly connected to the middle of the inner wall of the rake body 1. Worms 702 are rotatably connected to both the left and right sides of the mounting plate 701, and the ends of both worms 702 penetrate the side wall of the rake body 1 and extend to the outside of the rake body 1. A second knob 703 is fixedly connected to the end of each worm 702, and a worm wheel 70 is fixedly sleeved on the surface of the rotating shaft 4. 4. Furthermore, the worm gear 704 meshes with the worm 702. It should be noted that by rotating the second knob 703, the worm 702 is driven to rotate, which in turn drives the worm gear 704 meshing with it to rotate. The worm gear 704 drives the rotating shaft 4 and the mounting box 5 to rotate, which in turn drives the rake tooth assembly 3 to rotate. This causes the angle between the rake tooth assembly 3 and the forward direction of the live slag rake to change. When the angle changes, the rake tooth assembly 3 crushes salt blocks of different particle sizes, thereby changing the crushing effect.

[0031] As shown in Figure 1, there are two sets of rake tooth components 3, and the two sets of rake tooth components 3 are oriented in opposite directions. More specifically, by setting two sets of rake tooth components 3 with opposite orientations, when the traction equipment drives the rake to move forward or backward during the salt field slag removal, the rake tooth components 3 can break the salt crystals without changing the direction of the rake.

[0032] As shown in Figures 1 and 5, sensor 9 is a contact switch and is electrically connected to the robotic arm of the traction device. It should be noted that by setting the contact switch, when the plastic tarpaulin take-up rope comes into contact with sensor 9, it will press on sensor 9, thereby feeding back the robotic arm of the traction device to operate. The robotic arm lifts the live slag rake, so that the live slag rake passes over the plastic tarpaulin take-up rope.

[0033] As shown in Figure 1, the cross-sectional projection of the rope retraction frame 8 covers the rake tooth assembly 3. More specifically, by setting a larger rope retraction frame 8, the rope retraction frame 8 can come into contact with the plastic tarpaulin take-up rope between the rake tooth assembly 3, thus preventing the plastic tarpaulin take-up rope from coming into contact with the rake tooth assembly 3 and preventing the plastic tarpaulin take-up rope from being cut by the working surface of the rake tooth assembly 3.

[0034] As shown in Figures 1 and 3, the surface of the rope retraction frame 8 is coated with polytetrafluoroethylene wear-resistant lubricating material, the rake body 1 is made of stainless steel, and the rake tooth assembly 3 is made of supercooled austenitic carbon steel or alloy steel. It should be noted that by using stainless steel, supercooled austenitic carbon steel or alloy steel to make the live slag rake, the corrosion resistance of the rake body 1 and the wear resistance of the rake tooth assembly 3 are improved.

[0035] In summary, this invention uses a traction device to move the entire movable salt rake, allowing the rake tooth assembly 3 to contact large salt crystals in the salt field and crush them. The angle adjustment assembly 7 controls the rotation of the rotating shaft 4 and the mounting box 5, thereby rotating the rake tooth assembly 3 and changing the angle between the rake tooth assembly 3 and the moving direction of the movable salt rake. This adjusts the crushing effect on the salt blocks, adapting to different crushing needs and ensuring crushing efficiency. When the rake tooth assembly 3 wears out, the locking assembly 6 releases the restriction on the rake tooth assembly 3, allowing for quick disassembly and replacement with a new one. This ensures the continuous crushing effect of the movable salt rake and further guarantees crushing efficiency. When the live slag rake is moving, sensor 9 comes into contact with the plastic tarpaulin's take-up and release rope. The sensor 9 sends feedback to the operator, who can then control the robotic arm of the traction device to lift the live slag rake so that it passes over the rope surface, thus preventing the plastic tarpaulin's take-up and release rope from getting tangled with the live slag rake during operation.
