Description

Technical Field

[0001] This utility model relates to the field of recycled sand preparation technology, specifically to a concrete recycled sand preparation device. Background Technology

[0002] The equipment for preparing recycled concrete sand is a device that uses physical crushing to break down concrete fragments into finer particles, forming concrete sand particles that can be reused, thus avoiding resource waste.

[0003] Chinese patent CN220258156U discloses a concrete recycled sand preparation equipment for producing recycled sand raw materials.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: In actual use, the above solutions directly crush the raw materials through the rotating grinding structure. When there are large-particle blocky solid raw materials, there is a risk that the rotating crushing structure will get stuck, which will cause damage to the above-mentioned device.

[0005] This utility model proposes a concrete recycled sand preparation equipment to solve the problem. Summary of the Invention

[0006] The purpose of this invention is to overcome the problems mentioned above by pre-compressing and crushing the raw materials, thereby avoiding jamming during the grinding and crushing process.

[0007] Based on the above technical concept, the technical solution adopted by this utility model is as follows: A concrete recycled sand preparation device includes a base, a support column connected to the top of the base, a shell connected to the top of the support column, a collection hopper connected to the top of the base, a cover plate connected to the top of the shell, a feed hopper connected through the top of the cover plate, a grinding component rotatably connected inside the shell, and an extrusion component connected to the bottom of the cover plate, for preliminary extrusion and crushing processing of concrete raw materials.

[0008] Further defining the above technical solution, the grinding component includes a motor bracket connected to the outer side of the housing, and the motor bracket is connected to a rotating motor, which enables stable rotational transmission of the grinding roller.

[0009] Further defining the above technical solution, the output end of the rotating motor is connected to a grinding roller through the side of the housing. The grinding roller is located inside the housing and is rotatably connected to the inner wall of the housing. The structure of two symmetrical sets of grinding rollers can achieve a symmetrical extrusion effect on the raw material, thereby making the raw material more stable under force while ensuring the feeding effect at the center of the device.

[0010] Further defining the above technical solution, the housing is provided with two grinding rollers. The end of the grinding roller away from the rotating motor is connected to a rotating shaft, which passes through the side of the housing. The other end of the rotating shaft is connected to a transmission gear. The two sets of transmission gears set on the two sets of rotating shafts mesh with each other. Through the transmission connection of the transmission gears, the two sets of symmetrical grinding rollers can rotate in opposite directions, thereby ensuring that the material can be squeezed against each other.

[0011] Further defining the above technical solution, the extrusion component includes an air compressor connected to the outside of the housing. The output end of the air compressor is connected to a connecting air pipe, and the other end of the connecting air pipe is connected to a pneumatic telescopic rod. By adopting a pneumatic transmission method, static extrusion can be performed when the extrusion component can no longer be extruded, thereby avoiding the problem of burning out the power equipment when the transmission of traditional rigid transmission components jams.

[0012] Further defining the above technical solution, the telescopic end of the pneumatic telescopic rod extends through the side of the housing, and a spring bracket is connected to the telescopic end of the pneumatic telescopic rod. A spring is connected to the other end of the spring bracket, and a sliding bracket is connected to the other end of the spring. The combination of the spring bracket and the spring can buffer the extrusion component. When the extrusion component cannot slide, the spring compression can increase the extrusion force of the extrusion component.

[0013] Further defining the above technical solution, the sliding bracket has a sliding groove on the side away from the spring, a sliding column is slidably connected to the inner wall of the sliding groove, a connector is connected to the other end of the sliding column, and a number of equally spaced extrusion members are connected to the other end of the connector. The extrusion and crushing efficiency of this device can be improved by using multiple sets of extrusion members.

[0014] Further defining the above technical solution, the extrusion components are symmetrically arranged below the cover plate, the bottom of the cover plate is provided with a guide groove, the top of the connector is provided with a driven guide, the driven guide is slidably connected to the inner wall of the guide groove, the bottom of the sliding bracket is connected with a telescopic rod, and the two ends of the telescopic rod are respectively connected to the bottom of the symmetrical sliding bracket. The combination of the guide groove and the sliding groove can effectively improve the guiding sliding stability of the device, thereby enabling the extrusion components to slide horizontally towards each other when they are close to each other, thus improving the extrusion crushing efficiency.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. Stable feeding and discharging: The device can be easily connected through the top feeding hopper and the bottom collecting hopper 3, which reduces the difficulty of using the device. 2. Stable sealing: The combination structure of the cover plate and the shell of this device can achieve a sealed internal environment, thereby avoiding the problem of raw materials splashing during the production and processing process. 3. To avoid jamming, the device's pre-treatment of crushing and extrusion can effectively improve its working stability and reduce the risk of jamming. Attached Figure Description

[0019] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.

[0020] Example 1: This example provides a concrete recycled sand preparation device, such as... Figures 1-4 As shown, it includes a base 1, a support column 2 connected to the top of the base 1, a housing 4 connected to the top of the support column 2, a collection hopper 3 connected to the top of the base 1, a cover plate 5 connected to the top of the housing 4, a feed hopper 6 connected through the top of the cover plate 5, a grinding component 7 rotatably connected inside the housing 4, and an extrusion component 8 connected to the bottom of the cover plate 5, which is used for preliminary extrusion and crushing of concrete raw materials.

[0021] The grinding component 7 includes a motor bracket 702 connected to the outer side of the housing 4, and the motor bracket 702 is connected to a rotating motor 701.

[0022] The output end of the rotating motor 701 passes through the side of the housing 4 and is connected to a grinding roller 703. The grinding roller 703 is located inside the housing 4 and is rotatably connected to the inner wall of the housing 4.

[0023] The housing 4 is equipped with two grinding rollers 703. The end of the grinding roller 703 away from the rotating motor 701 is connected to a rotating shaft. The rotating shaft passes through the side of the housing 4, and the other end of the rotating shaft is connected to a transmission gear 704. The two sets of transmission gears 704 set on the two sets of rotating shafts are meshed with each other.

[0024] The extrusion component 8 includes an air compressor 801 connected to the outside of the housing 4. The output end of the air compressor 801 is connected to a connecting air pipe 802, and the other end of the connecting air pipe 802 is connected to a pneumatic telescopic rod 803.

[0025] The telescopic end of the pneumatic telescopic rod 803 extends through the four sides of the housing. A spring bracket 805 is connected to the telescopic end of the pneumatic telescopic rod 803. A spring 806 is connected to the other end of the spring bracket 805. A sliding bracket 807 is connected to the other end of the spring 806.

[0026] The specific working principle is as follows: This device can achieve the pre-crushing and processing effect of concrete raw materials. Compared with traditional devices, this device pre-crushes and screens the raw materials through the telescopic rod 813, so that only raw materials with a particle diameter smaller than the distance between the telescopic rods 813 can enter the grinding roller 703, thereby ensuring the processing stability of this device.

[0027] Example 2: This example provides a concrete recycled sand preparation device, such as... Figures 1-4 As shown, the sliding bracket 807 has a sliding groove 808 on the side away from the spring 806. A sliding column 809 is slidably connected to the inner wall of the sliding groove 808. A connector 810 is connected to the other end of the sliding column 809. A number of equally spaced extrusion pieces 811 are connected to the other end of the connector 810.

[0028] The extrusion components 8 are symmetrically arranged below the cover plate 5. The bottom of the cover plate 5 is provided with a guide groove 804. The top of the connector 810 is provided with a driven guide. The driven guide is slidably connected to the inner wall of the guide groove 804. The bottom of the sliding bracket 807 is connected with a telescopic rod 813. The two ends of the telescopic rod 813 are respectively connected to the bottom of the symmetrical sliding bracket 807.

[0029] The specific working principle is as follows: This device can effectively improve the crushing and processing efficiency and stability of concrete raw materials. When the device is in use, the concrete production raw materials can be easily poured into the shell 4 of the device through the structure of the feeding hopper 6. The raw materials with larger diameters are blocked by the telescopic rod 813 and thus located between the extrusion parts 811. At this time, the pneumatic air compressor 801 can transmit high-pressure air to the pneumatic telescopic rod 803 through the connecting air pipe 802, thereby causing the pneumatic telescopic rod 803 to drive the spring bracket 805 to slide linearly. The spring bracket 805 drives the sliding bracket 807 to slide through the spring 806. The spring 806 plays an elastic buffering role. During the sliding process, the sliding bracket 807 achieves the effect of horizontal reciprocating linear sliding under the combination of the connecting part 810 sliding column 809 and the sliding groove 808 and the dual guidance combination of the driven guide and the guide groove 804, thereby improving the crushing efficiency of the device.

[0030] When the diameter of the raw material is smaller than the distance between the telescopic rods 813, the raw material falls between the grinding rollers 703. At this time, the rotating motor 701 is started to drive the two sets of grinding rollers 703 to rotate in opposite directions, thereby achieving the effect of further grinding and processing of the raw material.

[0031] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
