Description

Technical Field

[0001] This utility model relates to the field of soil remediation agent production technology, specifically to a raw material shearing and crushing device for soil remediation agent production. Background Technology

[0002] The preparation of soil remediation agents involves a variety of raw materials and processes. The core lies in selecting the appropriate formula according to the type of pollution. Common raw materials include biochar, zeolite, bentonite, activated carbon, lime, calcium carbonate, phosphate, zero-valent iron, persulfate, ozone, microbial agents, corrosive acids, and nanomaterials. For example, raw materials such as biochar, zeolite, and lime need to be crushed and ground before preparing soil remediation agents, especially mineral raw materials, in order to facilitate subsequent mixing.

[0003] In existing raw material shearing and crushing equipment for soil remediation agent production, the crushing teeth suffer the most severe wear when shearing and crushing the raw materials. After wear or breakage, the entire crushing roller or multiple crushing discs in combination need to be replaced. Even on the crushing disc, there are several crushing teeth. The entire replacement not only requires removing the roller and crushing disc from the equipment, which is cumbersome and labor-intensive, but also requires replacing other teeth that have not broken or are not severely worn, resulting in a lot of waste. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a raw material shearing and crushing device for the production of soil remediation agents, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material shearing and crushing device for producing soil remediation agents, comprising a main body and a support roller, wherein a support wheel is sleeved on the outside of the support roller, and a base is fixed on the top of the support wheel, and an insert is fixed on the top of the base; a slot is opened on one side of the top of the support roller, and a crushing tooth is connected between the insert and the slot; a first bolt passes through both sides of the outer surface of the crushing tooth; a first insert plate and a second insert plate are respectively connected to both sides of the support wheel, and a second bolt passes through the inside of the first insert plate and the second insert plate.

[0006] By adopting the above technical solution, during the crushing process, the first and second insert plates cover the area of ​​the support wheel without crushing teeth, thus protecting the support wheel. The easily worn surface of the support wheel that originally participated in the crushing is replaced by the wear of the first and second insert plates. The first and second insert plates can be disassembled and replaced using the second bolt. Compared with replacing the support wheel by replacing the easily worn surface, there is no need to remove the support roller from the main body of the equipment, making the replacement operation faster. When the crushing teeth are damaged, the operator can remove the corresponding first bolt to disassemble and replace the damaged crushing teeth. The new crushing teeth are directly fitted onto the outside of the insert bar, preventing the crushing tooth fragments from shifting and falling off. They can also transfer the force to the support wheel for distribution during crushing. At the same time, the base thickens the root of the insert bar, and the presence of the slot increases the contact area between the bottom of the crushing teeth and the support wheel. The side of the crushing teeth can fit snugly against the support wheel to transfer force, so that most of the force during crushing is borne by the support wheel, and a small part is borne by the thickened insert bar at the root. This increases the structural connection strength and prevents the insert bar from breaking. After the crushing teeth are placed, the operator tightens them with the first bolt to complete the limit.

[0007] Furthermore, the cross-section of the breaking tooth is T-shaped, and the breaking tooth is detachably connected to the slot and the insert by bolts.

[0008] By adopting the above technical solution, the presence of the slot increases the contact area between the bottom of the crushing tooth and the support wheel, so that most of the force when the crushing tooth is crushed is borne by the support wheel, and a small part is borne by the thickened insert at the root, thereby increasing the structural connection strength and preventing the insert from breaking.

[0009] Furthermore, the side of the crushing tooth abuts against the side of the support wheel.

[0010] By adopting the above technical solution, the side of the crushing tooth can fit closely with the support wheel to transmit force, so that most of the force when the crushing tooth is crushed is borne by the support wheel, and a small part is borne by the thickened insert at the root, which increases the structural connection strength and avoids the breakage of the insert.

[0011] Furthermore, the base is trapezoidal.

[0012] By adopting the above technical solution, the base is used to thicken the root of the insert, thereby increasing the structural strength of the insert and reducing the occurrence of root breakage.

[0013] Furthermore, the first insert plate is compatible with the second insert plate.

[0014] By adopting the above technical solution, the first insert plate and the second insert plate are inserted together, forming a complete circle on the outside that can cooperate with the crushing structure on the other side to crush the raw materials, while forming a complete polygon on the inside that fits with the support wheel, thus preventing the first insert plate and the second insert plate from shifting arbitrarily.

[0015] Furthermore, both the first insert plate and the second insert plate are detachably connected to the support wheel via the second bolt.

[0016] By adopting the above technical solution, the first and second insert plates can be disassembled and replaced by the second bolt. Compared with replacing the support roller when the wear surface of the support roller is worn, there is no need to remove the support roller from the main body of the equipment, making the replacement operation faster.

[0017] Furthermore, multiple of the breaking teeth, first bolts, slots, bases, and inserts are provided, and the multiple breaking teeth, first bolts, slots, bases, and inserts are distributed in a ring array.

[0018] By adopting the above technical solution, multiple breaking teeth, first bolts, slots, bases and inserts are distributed in a ring array, which facilitates the individual replacement of multiple breaking teeth on the support wheel.

[0019] Furthermore, a motor is installed on the outer surface of the main body of the equipment, and support rollers are connected to both sides inside the main body of the equipment. One end of each support roller is connected to a gear, and the other end of one of the support rollers is connected to the output end of the motor through a coupling. A feed hopper is connected to the top of the main body of the equipment.

[0020] By adopting the above technical solution, when preparing soil remediation agent, the staff turns on the motor. After the motor starts, the output end drives a support roller to rotate. Through the meshing of two gears, the two support rollers rotate in opposite directions, thereby causing multiple support wheels and multiple sets of crushing teeth on the two support rollers to rotate in opposite directions. The staff puts the soil remediation agent mineral raw materials or raw materials that need to be sheared and crushed into the feed hopper. The raw materials are sheared and crushed by multiple sets of crushing rollers rotating in opposite directions. The crushed fine particles are discharged from the bottom of the main body of the equipment. A conveying structure can be set at the bottom of the equipment in advance to facilitate the feeding of the sheared and crushed fine particles into the screening equipment.

[0021] Furthermore, the support wheel, crushing tooth, base, insert bar, first insert plate and second insert plate are all made of hard alloy material.

[0022] By adopting the above technical solution and using cemented carbide, the cemented carbide has high hardness, high strength, and wear resistance, and can be used for a long time to reduce replacement intervals.

[0023] Furthermore, the support wheel, base, and insert are an integral structure.

[0024] By adopting the above technical solution, the blank of the support wheel is formed by pressing it with powder metallurgy. The blank has a margin for processing the base, insert and slot. Then, the workers drill, cut and groove the blank by means of electrical discharge, laser and other methods to complete the forming of the support wheel, base, insert and slot. After heat treatment, the performance is improved and the integrated structure has higher strength.

[0025] In summary, the present invention has the following main advantages: 1. This utility model, through the arrangement of the crushing tooth, the first bolt, and the insert, allows for the replacement of a damaged crushing tooth when it is severely worn or broken by removing the corresponding first bolt. The new crushing tooth is directly fitted onto the outside of the insert, preventing the crushing tooth fragments from shifting and falling off. It also allows the force to be transferred to the support wheel for distribution during crushing. After the crushing tooth is placed, it is secured by tightening the first bolt to achieve the limiting position. The split structure allows for the individual replacement of a crushing tooth and the support wheel when they are damaged, eliminating the need for overall replacement and reducing waste. 2. This utility model, through the setting of a base and a slot, thickens the root of the insert bar by the base, and the presence of the slot increases the contact area between the bottom of the crushing tooth and the support wheel, and the side of the crushing tooth can fit closely with the support wheel to transmit force, so that most of the force when the crushing tooth breaks is borne by the support wheel, and a small part is borne by the thickened insert bar at the root, thereby increasing the structural connection strength and preventing the insert bar from breaking; increasing connection strength and extending service life. 3. This utility model, through the arrangement of the first insert plate, the second insert plate, and the second bolt, covers the non-breakable tooth area of ​​the support wheel, thus protecting the support wheel. The easily worn surface of the support wheel that was originally involved in breakage is replaced by the wear of the first and second insert plates. The first and second insert plates can be disassembled and replaced by the second bolt. Compared with replacing the support wheel by replacing the easily worn surface, there is no need to remove the support roller from the main body of the equipment, making the replacement operation faster. It is convenient to protect the easily worn surface of the support wheel, and the protective structure is easy to replace. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] Example 1: A raw material shearing and crushing device for the production of soil remediation agents, such as Figures 1-5 As shown, the device includes a main body 1 and a support roller 4. A support wheel 6 is sleeved on the outside of the support roller 4. A base 10 is fixed to the top of the support wheel 6. The base 10 is trapezoidal, and an insert 11 is fixed to the top of the base 10. A slot 9 is opened on one side of the top of the support roller 4. A breaking tooth 7 is connected between the insert 11 and the slot 9. The cross-section of the breaking tooth 7 is T-shaped. The side of the breaking tooth 7 abuts against the side of the support wheel 6. First bolts 8 penetrate both sides of the outer surface of the breaking tooth 7. The breaking tooth 7 is detachably connected to the slot 9 and the insert 11 by bolts. Multiple breaking teeth 7, first bolts 8, slots 9, bases 10 and inserts 11 are provided. Multiple breaking teeth 7, first bolts 8, slots 9, bases 10 and inserts 11 are arranged in a ring array. When the breaking tooth 7 is damaged, the worker can remove the corresponding first bolt 8 to disassemble and replace the damaged breaking tooth 7. The new breaking tooth 7 is directly fitted onto the outside of the insert 11 to prevent the fragments of the breaking tooth 7 from shifting and falling off. It can also transfer the force to the support wheel 6 for distribution during breaking. At the same time, the base 10 thickens the root of the insert 11, and the presence of the slot 9 increases the contact area between the bottom of the breaking tooth 7 and the support wheel 6. The side of the breaking tooth 7 can fit closely with the support wheel 6 to transmit force, so that most of the force when the breaking tooth 7 breaks is borne by the support wheel 6, and a small part is borne by the thickened insert 11 at the root. This increases the structural connection strength and prevents the insert 11 from breaking. After the breaking tooth 7 is placed, the worker tightens it with the first bolt 8 to complete the positioning. The support wheel 6 is connected to a first insert plate 12 and a second insert plate 13 on both sides. The first insert plate 12 and the second insert plate 13 are adapted to each other. The first insert plate 12 and the second insert plate 13 are penetrated by a second bolt 14. The first insert plate 12 and the second insert plate 13 are detachably connected to the support wheel 6 by the second bolt 14. During the crushing process, the area of ​​the support wheel 6 without crushing teeth 7 is covered by the first insert plate 12 and the second insert plate 13, which can protect the support wheel 6. The wear surface of the support wheel 6 that originally participated in the crushing is replaced by the wear of the first insert plate 12 and the second insert plate 13. The first insert plate 12 and the second insert plate 13 can be disassembled and replaced by the second bolt 14. Compared with replacing the support wheel 6 by replacing the wear surface of the support wheel 6, it is not necessary to remove the support roller 4 from the main body 1 of the equipment, and the replacement operation is faster.

[0031] See Figure 1 In the above embodiment, a motor 3 is installed on the outer surface of the main body 1, and support rollers 4 are connected to both sides inside the main body 1. One end of each support roller 4 is connected to a gear 5, and the other end of one support roller 4 is connected to the output end of the motor 3 through a coupling. A feed hopper 2 is connected to the top of the main body 1. When preparing soil remediation agent, the operator turns on the motor 3. After the motor 3 starts, the output end drives one support roller 4 to rotate. The two support rollers 4 rotate in opposite directions through the meshing of the two gears 5, so that the multiple support wheels 6 and multiple sets of crushing teeth 7 on the two support rollers 4 rotate in opposite directions. The operator puts the soil remediation agent mineral raw materials or raw materials that need to be sheared and crushed into the feed hopper 2. The raw materials are sheared and crushed by multiple sets of crushing rollers rotating in opposite directions. The crushed fine particles are discharged from the bottom of the main body 1. A conveying structure can be set at the bottom of the equipment in advance to facilitate the feeding of the sheared and crushed fine particles into the screening equipment.

[0032] Example 2: Based on the above embodiment one, the following settings are now implemented to extend the service life of the structure.

[0033] See Figures 1-5 In the above embodiments, the support wheel 6, the breaking tooth 7, the base 10, the insert 11, the first insert plate 12 and the second insert plate 13 are all made of hard alloy material. Hard alloy has high hardness and wear resistance, and can be used for a long time with reduced replacement intervals.

[0034] Example 3: Based on the above embodiment one, the following settings are now adopted to increase structural strength.

[0035] See Figure 4In the above embodiment, the support wheel 6, the base 10, and the insert 11 are an integral structure. The workers use powder metallurgy to press and form the blank of the support wheel 6. The blank has a margin for processing the base 10, the insert 11, and the slot 9. Then, the workers use electrical discharge machining, laser and other methods to drill, cut and groove the blank to complete the forming of the support wheel 6, the base 10, the insert 11 and the slot 9. After heat treatment, the performance is increased, and the integral structure has higher strength.

[0036] The implementation principle of this utility model is as follows: First, the workers press and form the blank of the support wheel 6 using powder metallurgy process. The blank has a margin for processing the base 10, insert 11 and slot 9. Then, the workers drill, cut and groove the blank using electrical discharge machining, laser and other methods to complete the forming of the support wheel 6, base 10, insert 11 and slot 9. Then, the blank is heat treated to increase its performance. When preparing the soil remediation agent, the staff turns on the motor 3. After the motor 3 starts, the output end drives a support roller 4 to rotate. Through the meshing of two gears 5, the two support rollers 4 rotate in opposite directions, thereby causing multiple support wheels 6 and multiple sets of crushing teeth 7 on the two support rollers 4 to rotate in opposite directions. The staff puts the soil remediation agent mineral raw materials or raw materials that need to be sheared and crushed into the feed hopper 2. The raw materials are sheared and crushed by multiple sets of crushing rollers rotating in opposite directions. The crushed fine particles are discharged from the bottom of the main body 1 of the equipment. A conveying structure can be set at the bottom of the equipment in advance to facilitate the feeding of the sheared and crushed fine particles into the screening equipment. During the crushing process, the area of ​​the support wheel 6 without crushing teeth 7 is covered by the first insert plate 12 and the second insert plate 13, which can protect the support wheel 6. The wear surface of the support wheel 6 that originally participated in the crushing is replaced by the wear of the first insert plate 12 and the second insert plate 13. The first insert plate 12 and the second insert plate 13 can be disassembled and replaced by the second bolt 14. Compared with replacing the support wheel 6 by replacing the wear surface of the support wheel 6, there is no need to remove the support roller 4 from the main body 1 of the equipment, and the replacement operation is faster. When the breaking tooth 7 is damaged, the worker can remove the corresponding first bolt 8 to disassemble and replace the damaged breaking tooth 7. The new breaking tooth 7 is directly fitted onto the outside of the insert 11 to prevent the fragments of the breaking tooth 7 from shifting and falling off. It can also transfer the force to the support wheel 6 for distribution during breaking. At the same time, the base 10 thickens the root of the insert 11, and the presence of the slot 9 increases the contact area between the bottom of the breaking tooth 7 and the support wheel 6. The side of the breaking tooth 7 can fit closely with the support wheel 6 to transfer force, so that most of the force when the breaking tooth 7 breaks is borne by the support wheel 6, and a small part is borne by the thickened insert 11 at the root. This increases the structural connection strength and prevents the insert 11 from breaking. After the breaking tooth 7 is placed, the worker tightens it with the first bolt 8 to complete the limit. To prevent the first bolt 8 and the second bolt 14 from loosening, anti-loosening washers or other bolt anti-loosening structures can be set, or detachable anti-loosening bolts can be used as the first bolt 8 and the second bolt 14.
