Description

Technical Field

[0001] The utility model relates to the technical field of concrete block crushing, in particular to a crushing device for reinforced concrete blocks. Background Art

[0002] With the rapid economic development and urbanization in my country, the amount of construction waste generated and discharged has increased rapidly. In order to promote the establishment of a resource-saving society, on construction sites, reinforced concrete blocks are generally crushed using crushing devices for later recycling. However, the existing crushing devices for reinforced concrete blocks are not efficient and cannot meet actual needs.

[0003] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: the existing crushing devices for reinforced concrete blocks mostly place corresponding cover plates on the upper side of the feeding mechanism to prevent the splashing of gravel caused by crushing, but before and after the waste is put in, manpower is required to take and place the cover plates. The process is relatively cumbersome, time-consuming and labor-intensive, and urgently needs to be improved. Therefore, we propose a crushing device for reinforced concrete blocks. Utility Model Content

[0004] The utility model aims to provide a crushing device for reinforced concrete blocks, which solves the problems raised in the background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a reinforced concrete block crushing device, comprising a crusher body, a fence fixedly installed on the top of the crusher body, blocks placed on both sides of the fence, and baffles placed on both sides of the top of the fence;

[0006] A concave platform is integrally formed in the enclosure, a gantry is fixedly installed on the concave platform, and a limiting block is fixedly installed on one side of the concave platform close to the gantry;

[0007] A sealing strip is fixedly installed on the outer edge of the baffle, and grooves are provided on both sides of the baffle;

[0008] A support rod is fixedly installed in the gantry, and the support rod movably penetrates the baffle plate. Torsion springs are sleeved on both sides of the support rod, and the two ends of the torsion spring are respectively connected to the gantry and the baffle plate;

[0009] A material receiving trough is placed directly below the discharge port of the crusher body, which can be used in conjunction with components such as a baffle, a torsion spring and a gantry. During the use of the crushing device for reinforced concrete blocks, waste materials can be placed on the baffle. At this time, the baffle is subjected to force and rotates downward with the support rod as the center, causing the waste materials to fall downward. Subsequently, the reaction force of the torsion spring causes the baffle to rotate upward, and the limit block resists to block the opening of the enclosure. This structure can prevent the fragments from splashing due to crushing, and the baffle rotates adaptively without the need for manual adjustment.

[0010] As an optional scheme of the technical solution of the present application, a hanging ring is fixedly installed at the bottom of the baffle, and a nylon rope is wound and fixed on the hanging ring. The nylon rope movably passes through the wire hole on one side of the inner wall of the enclosure, and the outer end of the nylon rope is fixedly connected to the block, which can be used in combination with components such as the nylon rope and the block. If the weight of the waste material is not enough to rotate the baffle, the block can be held and moved outward with force, and the nylon rope moves outward, so that the baffle can be rotated downward. After unloading is completed, the block is released to automatically reset the baffle. This structure is used to assist unloading, and compared with manually pressing down the baffle, it can avoid safety hazards.

[0011] As an optional solution of the technical solution of the present application, a handle is fixedly installed on the block, and an anti-slip cover is fixedly installed on the handle. A person can hold the handle to apply force to move the block, which is convenient for adjusting the block. At the same time, the anti-slip cover improves the holding comfort and friction.

The operator can be informed of the corresponding procedures through the indicator sign and the guiding text, which is convenient for operation and use.

[0013] As an optional solution of the technical solution of the present application, support rods are fixedly installed at the four corners of the bottom of the crusher body, and positioning blocks are fixedly installed at the bottom ends of the support rods. The crusher can be detachably fixed by the support rods and the positioning blocks to ensure its stable operation and support later repositioning and assembly.

[0015] 1. The utility model discloses a crushing device for reinforced concrete blocks. The device is provided with a baffle, a torsion spring and a gantry. When the crushing device for reinforced concrete blocks is used, waste materials can be placed on the baffle. At this time, the baffle is subjected to force and rotates downward with the support rod as the center, so that the waste materials fall downward. Subsequently, the reaction force of the torsion spring causes the baffle to rotate upward and is resisted by the limit block to block the opening of the enclosure. The structure can prevent the fragments from splashing due to the crushing. At the same time, the baffle rotates adaptively without manual adjustment.

[0016] 2. The utility model is a reinforced concrete block crushing device, which is provided with a nylon rope and a baffle. If the weight of the waste is not enough to rotate the baffle, the baffle can be held and moved outward with force. The nylon rope moves outward and the baffle can be rotated downward.

[0023] See also Figure 1-3The utility model provides a technical solution: a reinforced concrete block crushing device, including a crusher body 1, four corners of the bottom of the crusher body 1 are fixedly installed with support rods, and the bottom of the support rods is fixedly installed with positioning blocks, and the crusher can be detachably fixed by the support rods and the positioning blocks to ensure its stable operation and support later relocation assembly, a fence 2 is fixedly installed on the top of the crusher body 1, an indicator board 21 is fixedly installed on the top of the front side of the fence 2, and guide text is printed on the indicator board 21, and the corresponding process can be informed to the operator through the indicator board 21 and the guide text, which is convenient for operation and use, blocks 3 are placed on both sides of the fence 2, baffles 4 are placed on both sides of the top of the fence 2, and handles 3 are fixedly installed on the block 3 1, and an anti-slip sleeve is fixedly installed on the handle 31. A person can apply force to move the stopper 3 by holding the handle 31, which is convenient for adjusting the stopper 3. At the same time, the anti-slip sleeve improves the grip comfort and friction; a recessed platform 22 is integrally formed in the enclosure 2, and a gantry 5 is fixedly installed at the recessed platform 22, and a limited block 23 is fixedly installed on the side of the recessed platform 22 close to the gantry 5; a sealing strip 41 is fixedly installed on the outer edge of the baffle 4, and grooves 42 are provided on both sides of the baffle 4; a support rod 51 is fixedly installed in the gantry 5, and the support rod 51 movably passes through the baffle 4, and torsion springs 52 are sleeved on both sides of the support rod 51, and the two ends of the torsion spring 52 are respectively connected to the gantry 5 and the baffle 4; a receiving trough 11 is placed just below the discharge port of the crusher body 1.

[0024] In this technical solution, the baffle 4, torsion spring 52, gantry 5 and other components can be used in combination. During the use of the crushing device for reinforced concrete blocks, the waste can be placed on the baffle 4. At this time, the baffle 4 is subjected to force and rotates downward with the support rod 51 as the center, causing the waste to fall downward. Subsequently, the reaction force of the torsion spring 52 causes the baffle 4 to rotate upward, and is resisted by the limit block 23 to block the opening of the enclosure 2. This structure can prevent the fragments from splashing due to crushing. At the same time, the baffle 4 rotates adaptively without the need for manual adjustment.

[0025] In some technical solutions, a hanging ring 33 is fixedly installed at the bottom of the baffle 4, and a nylon rope 32 is wrapped and fixed on the hanging ring 33. The nylon rope 32 is movable through the wire hole 24 on one side of the side wall of the enclosure 2, and the outer end of the nylon rope 32 is fixedly connected to the baffle 3.

[0026] In this technical solution, the nylon rope 32 and the block 3 and other components can be used together. If the weight of the waste is not enough to rotate the baffle 4, the block 3 can be held and moved outward with force. The nylon rope 32 moves outward and the baffle 4 can be rotated downward. After unloading is completed, the block 3 is released to automatically reset the baffle 4. This structure is used to assist unloading and can avoid safety hazards compared to manually pressing down the baffle 4.

[0027] Working principle: It should be noted that the utility model is a crushing device for reinforced concrete blocks. All components are universal standard parts or components known to technical personnel in this field. Its structure and principle can be known to technical personnel through technical manuals or through conventional test methods.

[0028] When a crushing device for reinforced concrete blocks is used, the crushing device is placed at a reinforced concrete block processing station, and the device is connected to an external power supply. During this period, waste materials enter the enclosure 2, fall into the crusher body, and after being crushed, fall into the receiving trough 11 for crushing reinforced concrete blocks;

[0029] By providing the baffle plate 4, torsion spring 52 and gantry 5, during the use of the crushing device for reinforced concrete blocks, the waste can be placed on the baffle plate 4. At this time, the baffle plate 4 is subjected to force and rotates downward with the support rod 51 as the center, so that the waste falls downward. Then, the reaction force of the torsion spring 52 causes the baffle plate 4 to rotate upward and is resisted by the limit block 23 to block the opening of the enclosure 2. This structure can prevent the fragments from splashing due to crushing. At the same time, the baffle plate 4 rotates adaptively without manual adjustment. By providing the nylon rope 32 and the baffle block 3, if the weight of the waste is not enough to rotate the baffle plate 4, the baffle block 3 can be held and forcefully moved outward. The nylon rope 32 moves outward to cause the baffle plate 4 to rotate downward. After the unloading is completed, the baffle block 3 is released to automatically reset and rotate. This structure is used to assist in unloading. Compared with manually pressing down the baffle plate 4, it can avoid safety hazards.
