Description

Technical Field

[0001] This utility model belongs to the field of soil crushing machine technology, and in particular relates to a soil crushing machine for soil remediation. Background Technology

[0002] Soil crushers, also known as soil breakers, are typically used in soil remediation projects to break up soil. These machines play an important role in the soil remediation process by using rotating crushing rods or rollers to break the soil into smaller particles.

[0003] For example, Chinese patent CN212549791U discloses a soil shredder for soil remediation, including a shell with support legs fixedly installed on both sides of the bottom of the shell. The top of the shell has a feed inlet, and the bottom has a guide inlet. A first motor is fixedly installed on the right side of the shell, and a protective shell is fixedly installed on the left side. A crushing chamber is formed inside the shell, and a screening chamber is formed inside the shell at the bottom of the crushing chamber. A crushing rod is installed inside the crushing chamber, and a screen is installed inside the screening chamber. This invention solves the problem that existing soil shredders cannot completely crush the soil by providing a feed inlet to deliver the soil to the shell, a guide inlet to discharge the crushed soil, a first motor to drive the crushing rod to crush the soil, and a second motor inside the protective shell to move the screen to screen the soil.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its use. For example, after prolonged use, the internal crushing rod of the aforementioned soil crusher may be damaged due to continuous impact with stones in the soil. When the crushing rod is damaged, because it is located inside the soil crusher's cavity, the user cannot quickly remove and replace it. Therefore, we propose a soil crusher for soil remediation. Utility Model Content

[0006] The purpose of this invention is to provide a soil shredder for soil remediation to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a soil shredder for soil remediation, comprising a soil shredder body, and further comprising:

[0008] A through groove is provided on one side of the body of the soil crusher and is connected to the inner cavity of the body of the soil crusher. A sealing plate is inserted into the through groove.

[0009] Two first chutes are symmetrically opened in the body of the soil crusher and connected to the inner cavity of the through chute. Two sliding rods are slidably connected in each of the two first chutes, and one end of each sliding rod is fixed to the sealing plate. The sliding rods are threaded with lead screws.

[0010] A drive assembly, located within the body of the soil crusher, is used to drive two lead screws to rotate;

[0011] A crushing rod is disposed in the inner cavity of the soil crusher body, and a slot is provided at one end of the crushing rod;

[0012] The first motor is fixedly connected to one side of the sealing plate, and the output shaft of the first motor passes through the sealing plate and extends into the body of the soil crusher and is rotatably connected to the sealing plate. A fixing block is fixedly connected to the output shaft of the first motor, and one end of the fixing block extends into the slot and is inserted into the slot. Two symmetrically arranged insertion holes are opened on the fixing block.

[0013] A fixing component is located inside the crushing rod and is used to fix the crushing rod.

[0014] Based on the above structure, the slots and fixing blocks ensure that one end of the fixing block can be inserted into the slots. The fixing components, crushing rod, and insertion holes ensure that the user can fix the crushing rod to one end of the fixing block and prevent it from moving through the fixing components and two insertion holes. The through groove and sealing plate ensure that the sealing plate can be inserted into the through groove to seal it. The first sliding groove and sliding rod ensure that the sliding rod can slide in the first sliding groove. The drive component and lead screws ensure that the user can drive the two lead screws to rotate through the drive component, so that the two sliding rods are driven by the two lead screw threads to move the sealing plate. When the sealing plate moves from the through groove to the outside and to the appropriate position, the sealing plate will drive the crushing rod from the inner cavity of the soil crusher body to the outside through the fixing block, so that the user can replace the crushing rod. The first motor ensures that when the first motor is started, it can drive the crushing rod to rotate in the inner cavity of the soil crusher body through the fixing block, so that the crushing rod can crush the soil.

[0015] In the above technical solution, the driving component further includes:

[0016] The movable groove is located inside the body of the soil crusher and is connected to two first sliding grooves. Two sprockets are rotatably connected inside the movable groove, and one end of each sprocket extends into the two first sliding grooves and is fixed to one end of each of the two lead screws. A chain meshes between the two sprockets.

[0017] The second motor is fixedly connected to the other side of the soil crusher body, and the output shaft of the second motor passes through the other side of the soil crusher body and extends into the movable groove to be fixed to one of the sprockets.

[0018] In this technical solution, it is ensured that the user can move the crushing rod from the body of the soil crusher to the outside.

[0019] In the above technical solution, the output shaft of the second motor is rotatably connected to the body of the soil crusher.

[0020] In this technical solution, it is ensured that the output shaft of the second motor can rotate normally within the body of the soil crusher.

[0021] In the above technical solution, the fixing component further includes:

[0022] Two second sliding grooves are symmetrically opened inside the crushing rod and connected to the slot. Two insert blocks are slidably connected in each of the two second sliding grooves, and one end of each insert block extends into two insertion holes and is inserted into the two insertion holes respectively. Two threaded rods are threadedly connected in each of the two insert blocks.

[0023] Two first rotating grooves are symmetrically opened inside the crushing rod and are respectively connected to two second sliding grooves. Two bevel gears are rotatably connected in each of the two first rotating grooves, and the two bevel gears are respectively fixed to one end of the two threaded rods.

[0024] The second rotating groove is located at one end of the crushing rod and is connected to the first rotating groove. A bevel gear ring that meshes with two bevel gears is rotatably connected inside the second rotating groove.

[0025] The third rotating groove is located on the periphery of the crushing rod. A rotating ring is rotatably connected inside the third rotating groove, and the rotating ring is fixed to the bevel gear ring.

[0026] This technical solution ensures that users can quickly replace the crushing rod.

[0027] Furthermore, in the above technical solution, the threads on the two threaded rods have the same direction of rotation.

[0028] In this technical solution, it is ensured that when the two threaded rods rotate in opposite directions, the two inserts are either moved away from or moved closer to each other by the action of the threads of the two threaded rods.

[0029] In the above technical solution, the insert block is further shaped like a "T".

[0030] In this technical solution, it is ensured that the insert block can only slide within the second groove.

[0031] In the above technical solution, furthermore, the threads on the two lead screws have the same direction of rotation.

[0032] In this technical solution, it is ensured that when the two lead screws rotate, the two slide bars will move in the same direction under the action of the two lead screw threads respectively.

[0033] The beneficial effects of this utility model are:

[0034] This soil shredder for soil remediation features a slot and a fixing block. One end of the fixing block can be inserted into the slot. A fixing component, a crushing rod, and two insertion holes allow the user to secure the crushing rod to one end of the fixing block, preventing it from moving. A through groove and a sealing plate seal the through groove. A first sliding groove and a sliding rod allow the sliding rod to slide within the first sliding groove. A drive component and lead screws allow the user to rotate the two lead screws, causing the two sliding rods to be subjected to the threads of the two lead screws. The sealing plate moves as it moves from the through groove to the outside and into a suitable position. The sealing plate then moves the crushing rod from the inner cavity of the soil crusher to the outside via a fixing block, facilitating replacement by the user. The included first motor ensures that when it starts, it can drive the crushing rod to rotate within the soil crusher's inner cavity via the fixing block, allowing the crushing rod to break up the soil. This solves the problem that when the crushing rod is damaged, the user cannot quickly remove and replace it because it is located within the soil crusher's inner cavity. Attached Figure Description

[0047] Example 1:

[0048] Please see Figure 1 - Figure 5 As shown, this embodiment provides a soil shredder for soil remediation, including a soil shredder body 1, and further comprising:

[0049] The through groove 2 is located on one side of the body 1 of the soil crusher and is connected to the inner cavity of the body 1 of the soil crusher. A sealing plate 3 is inserted into the through groove 2.

[0050] Two first chutes 4 are symmetrically opened inside the body 1 of the soil crusher and are connected to the inner cavity of the through groove 2. Two slide rods 5 are slidably connected in the two first chutes 4 respectively, and one end of the two slide rods 5 is fixed to the sealing plate 3. The slide rods 5 are threadedly connected to the lead screw 6.

[0051] The drive assembly is located inside the body 1 of the soil crusher and is used to drive the two lead screws 6 to rotate.

[0052] Crushing rod 7 is installed in the inner cavity of the soil crusher body 1, and a slot 8 is provided at one end of the crushing rod 7;

[0053] The first motor 9 is fixedly connected to one side of the sealing plate 3, and the output shaft of the first motor 9 passes through the sealing plate 3 and extends into the body 1 of the soil crusher and is rotatably connected to the sealing plate 3. A fixing block 10 is fixedly connected to the output shaft of the first motor 9, and one end of the fixing block 10 extends into the slot 8 and is inserted into the slot 8. Two symmetrically arranged insertion holes 11 are opened on the fixing block 10.

[0054] A fixing component is located inside the crushing rod 7 and is used to fix the crushing rod 7.

[0055] Example 2:

[0056] This embodiment provides a soil shredder for soil remediation. In addition to the technical solutions described in the above embodiments, it also has the following technical features, including a drive component comprising:

[0057] The movable groove 12 is opened inside the body 1 of the soil crusher and is connected to two first sliding grooves 4. Two sprockets 13 are rotatably connected inside the movable groove 12, and one end of each sprocket 13 extends into the two first sliding grooves 4 and is fixed to one end of each of the two lead screws 6. A chain 14 meshes between the two sprockets 13.

[0058] The second motor 15 is fixedly connected to the other side of the soil crusher body 1, and the output shaft of the second motor 15 passes through the other side of the soil crusher body 1 and extends into the movable groove 12 and is fixed to one of the sprockets 13.

[0059] When the crushing rod 7 is damaged during prolonged use, the user starts the second motor 15, causing the output shaft of the second motor 15 to drive one of the sprockets 13 to rotate in the movable groove 12. This causes one sprocket 13 to drive the other sprocket 13 to rotate via the chain 14. When the two sprockets 13 rotate, one end of each sprocket 13 will drive the two lead screws 6 to rotate in the two slide rods 5. The two slide rods 5 will be acted upon by the threads of the two lead screws 6 and move along the two first sliding grooves 4. When the two slide rods 5 move, they will drive the sealing plate 3 to move to the outside in the through groove 2. The sealing plate 3 will then drive the crushing rod 7 from inside the soil crusher body 1 to the outside, ensuring that the user can move the crushing rod 7 from inside the soil crusher body 1 to the outside.

[0060] Example 3:

[0061] This embodiment provides a soil crusher for soil remediation. In addition to the technical solutions of the above embodiments, it also has the following technical features: the output shaft of the second motor 15 is rotatably connected to the soil crusher body 1.

[0062] Among these measures, it is ensured that the output shaft of the second motor 15 can rotate normally within the body 1 of the soil crusher.

[0063] Example 4:

[0064] This embodiment provides a soil shredder for soil remediation. In addition to the technical solutions described in the above embodiments, it also has the following technical features, including a fixing component:

[0065] Two second slide grooves 16 are symmetrically opened in the crushing rod 7 and connected to the slot 8. Two insert blocks 17 are slidably connected in the two second slide grooves 16 respectively, and one end of the two insert blocks 17 extends into the two insertion holes 11 respectively and is inserted into the two insertion holes 11 respectively. Two threaded rods 18 are threadedly connected in the two insert blocks 17 respectively.

[0066] Two first rotating grooves 19 are symmetrically opened in the crushing rod 7 and are respectively connected to two second sliding grooves 16. Two bevel gears 20 are rotatably connected in the two first rotating grooves 19, and the two bevel gears 20 are respectively fixed to one end of the two threaded rods 18.

[0067] The second rotating groove 21 is opened at one end of the crushing rod 7 and is connected to the first rotating groove 19. A bevel ring 22 that meshes with two bevel gears 20 is rotatably connected in the second rotating groove 21.

[0068] The third rotating groove 23 is opened on the periphery of the crushing rod 7. A rotating ring 24 is rotatably connected inside the third rotating groove 23, and the rotating ring 24 is fixed to the bevel ring 22.

[0069] When the crushing rod 7 is fully moved to the outside, the user closes the threaded rod 18. Then, the user manually rotates the rotating ring 24, causing the bevel gear ring 22 to rotate within the second rotating groove 21. This causes the bevel gear ring 22 to drive the two bevel gears 20 to rotate in opposite directions within the two first rotating grooves 19. When the two bevel gears 20 rotate in opposite directions, they drive the two threaded rods 18 to rotate in opposite directions, causing the two insert blocks 17 to move away from each other due to the threaded action of the two threaded rods 18. One end of each insert block 17 then enters the two second sliding grooves 16 from the two insertion holes 11. At this point, the fixing of one section of the fixing block 10 is released. The user then manually pulls the crushing rod 7 out from one side of the fixing block 10 and replaces it. After replacement, the user... The user manually re-attaches the crushing rod 7 to one end of the fixing block 10, inserting one end of the fixing block 10 into the slot 8. Then, the user manually rotates the rotating ring 24 in the opposite direction, causing the rotating ring 24 to drive the bevel gear ring 22 to rotate in the second rotating groove 21 in the opposite direction. This causes the bevel gear ring 22 to drive the two bevel gears 20 to rotate in opposite directions in the two first rotating grooves 19. When the two bevel gears 20 rotate in opposite directions, they will drive the two threaded rods 18 to rotate in opposite directions. This causes the two insert blocks 17 to be brought closer together by the threads of the two threaded rods 18, so that one end of each insert block 17 is inserted from the two second sliding grooves 16 into the two insertion holes 11. This fixes the crushing rod 7 to one end of the fixing block 10, preventing it from moving and ensuring that the user can quickly replace the crushing rod 7.

[0070] Example 5:

[0071] This embodiment provides a soil crusher for soil remediation. In addition to the technical solutions of the above embodiments, it also has the following technical features: the threads on the two threaded rods 18 have the same direction of rotation.

[0072] Specifically, it is ensured that when the two threaded rods 18 rotate in opposite directions, the two inserts 17 are either moved away from or moved closer to each other by the action of the threads of the two threaded rods 18.

[0073] Example 6:

[0074] This embodiment provides a soil shredder for soil remediation. In addition to the technical solutions of the above embodiments, it also has the following technical features: the insert block 17 is T-shaped.

[0075] Specifically, this ensures that the insert 17 can only slide within the second slide groove 16.

[0076] Example 7:

[0077] This embodiment provides a soil shredder for soil remediation. In addition to the technical solutions of the above embodiments, it also has the following technical features: the threads on the two lead screws 6 have the same direction of rotation.

[0078] Specifically, it is ensured that when the two lead screws 6 rotate, the two slide rods 5 will move in the same direction due to the action of the threads of the two lead screws 6 respectively.

[0079] When the crushing rod 7 is damaged during prolonged use, the user starts the second motor 15, causing the output shaft of the second motor 15 to drive one of the sprockets 13 to rotate in the movable groove 12. This causes one sprocket 13 to drive the other sprocket 13 to rotate via the chain 14. When both sprockets 13 rotate, one end of each sprocket 13 will drive two lead screws 6 to rotate in two slide rods 5. This causes the two slide rods 5 to move along the two first sliding grooves 4 under the action of the threads of the two lead screws 6. As the two slide rods 5 move, they will drive the sealing plate 3 to move to the outside in the through groove 2. This allows the sealing plate 3 to move the crushing rod 7 from inside the crusher body 1 to the outside, ensuring that the user can move the crushing rod 7 from inside the crusher body 1 to the outside. When the crushing rod 7 has completely moved to the outside, the user closes the threaded rod 18. Then, the user manually rotates the rotating ring 24, causing the rotating ring 24 to drive the bevel gear ring 22 to rotate within the second rotating groove 21. This causes the bevel gear ring 22 to drive the two bevel gears 20 to rotate in opposite directions within the two first rotating grooves 19. When the two bevel gears 20 rotate in opposite directions, they will drive the two threaded rods 18 to rotate in opposite directions, causing the two insert blocks 17 to move away from each other due to the threaded action of the two threaded rods 18. This allows one end of each insert block 17 to enter the two second sliding grooves 16 from the two insertion holes 11. At this point, the fixing of one section of the fixing block 10 is released. The user then manually pulls the crushing rod 7 out from one side of the fixing block 10. Replace the crushing rod 7. After replacement, the user manually re-attaches the crushing rod 7 to one end of the fixing block 10, inserting one end of the fixing block 10 into the slot 8. Then, the user manually rotates the rotating ring 24 in the opposite direction, causing the rotating ring 24 to drive the bevel gear ring 22 to rotate in the second rotating groove 21 in the opposite direction. This causes the bevel gear ring 22 to drive the two bevel gears 20 to rotate in opposite directions in the two first rotating grooves 19. When the two bevel gears 20 rotate in opposite directions, they will drive the two threaded rods 18 to rotate in opposite directions, causing the two insert blocks 17 to be brought closer together by the threads of the two threaded rods 18. This allows one end of the two insert blocks 17 to be inserted from the two second sliding grooves 16 into the two insertion holes 11. The crushing rod 7 is fixed to one end of the fixing block 10 and cannot move, ensuring that the user can quickly replace the crushing rod 7. After replacement, the user restarts the second motor 15, causing the output shaft of the second motor 15 to drive one of the sprockets 13 to rotate in the opposite direction within the movable groove 12. This causes one sprocket 13 to drive the other sprocket 13 to rotate in the opposite direction via the chain 14. When the two sprockets 13 rotate in the opposite direction, one end of each sprocket 13 will drive the two lead screws 6 to rotate in the opposite direction within the two slide rods 5. This causes the two slide rods 5 to be acted upon by the threads of the two lead screws 6 and move in the opposite direction along the two first sliding grooves 4. When the two slide rods 5 move in the opposite direction, they will drive the sealing plate 3 to be inserted from the outside into the through groove 2, sealing the through groove 2. Afterwards...The user can then start the first motor 9, causing its output shaft to drive the crushing rod 7 to rotate within the inner cavity of the soil crusher body 1 via the fixed block 10, thus crushing the soil.

[0080] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
