Description
Technical Field
[0001] The utility model belongs to the technical field of concrete aggregate charging hoppers, and specifically relates to a recycled concrete aggregate charging hopper. Background Art
[0002] In construction projects and road construction, concrete is an important building material, and its quality is directly related to the safety and durability of the project. As the main component of concrete, the quality, particle size and uniformity of concrete aggregate have a vital impact on the performance of concrete. Therefore, the processing and treatment technology of concrete aggregate has always been the research focus in the construction field.
[0003] Traditional concrete aggregate hoppers often only have a simple feeding function and lack effective pre-treatment of aggregates, such as crushing and particle size control. This not only affects the quality of concrete aggregates, but may also lead to unstable concrete quality. Although some existing hopper designs take aggregate crushing into consideration, there are often problems such as unsatisfactory crushing effect and inaccurate particle size control.
[0004] In addition, as the use time increases, the crushing teeth inside the hopper are easily worn due to the continuous extrusion and friction of the aggregate, resulting in an increase in the material passing gap and failure of aggregate size control. This not only affects the working efficiency of the hopper, but may also cause the particle size of the concrete aggregate to fail to meet the engineering requirements.
[0005] In order to achieve this, we proposed a recycled concrete aggregate hopper, which not only realizes the effective crushing of aggregates and precise control of particle size, but also has the function of adjusting the feeding gap to adapt to the working requirements under different wear conditions, ensuring that the quality and particle size of concrete aggregates always meet the engineering requirements. Utility Model Content
[0006] The purpose of the utility model is to provide a recycled concrete aggregate feeding hopper, which can not only realize the effective crushing of aggregate and the precise control of particle size, but also has the function of adjusting the material passing gap to adapt to the working requirements under different wear conditions, so as to ensure that the quality and particle size of concrete aggregate always meet the engineering requirements.
[0007] The technical solutions adopted in this utility are as follows:
[0008] A recycled concrete aggregate hopper comprises a hopper body, the hopper body is conical, a plurality of first crushing teeth are arranged in an array on the inner wall of the hopper body, and the hopper body is arranged on a support plate through a bracket;
[0009] A fixed plate is provided on the top of the hopper body, a rotating assembly is provided on the fixed plate, a conical shell located inside the hopper body is installed on the rotating assembly, the conical shell is narrow at the top and wide at the bottom, and an adjustment assembly is provided inside the conical shell, and a conical sleeve is provided on the adjustment assembly;
[0010] A plurality of through holes are arranged in an array on the feeding hopper body, a connecting rod is movably arranged inside the through hole, a wedge plate fitting with the conical sleeve is installed at one end of the connecting rod, a second crushing tooth is installed at the other end of the connecting rod, and a spring is sleeved on the connecting rod.
[0011] Furthermore, the adjustment assembly includes a threaded rod rotatably arranged inside the conical shell, the threaded rod is threadedly connected to the conical sleeve, and the bottom of the threaded rod passes through the conical shell and is equipped with a rotating disk.
[0012] Furthermore, an opening and closing door is provided on the feeding hopper body, and the opening and closing door corresponds to the position of the rotating disk.
[0013] Furthermore, the rotating assembly includes a motor fixedly arranged on the fixed plate, and an output end of the motor is connected to the conical shell.
[0014] Furthermore, a collecting shell for supporting aggregates inside the hopper body is provided at the bottom of the supporting plate, and an inclined filter plate is provided inside the collecting shell, and the filter plate divides the collecting shell into two collecting areas.
[0015] Furthermore, two discharge ports are provided at the bottom of the collection shell.
[0016] The technical effects achieved by this utility model are:
[0017] When people put concrete aggregate into the hopper body, start the rotating assembly, and the conical shell starts to rotate. This rotation makes the second crushing tooth rotate as well, so the aggregate between the first crushing tooth and the second crushing tooth will be clamped and rubbed by the two, thereby achieving preliminary crushing. Since the hopper body and the conical shell are both designed to be conical, as the aggregate descends in the hopper, the space between the inner wall of the hopper body and the outer side of the conical shell gradually decreases, thereby further improving the degree of aggregate crushing and ensuring high-quality crushing effect. However, long-term use will cause the first crushing tooth and the second crushing tooth to gradually wear due to continuous extrusion and friction, resulting in a gradual increase in the material passing gap between them, which will affect the aggregate crushing particle size and make it less and less in line with the requirements. In order to solve this problem, we can use the adjustment assembly to adjust the position of the conical sleeve. When the conical sleeve moves upward, it squeezes the wedge plate, causing the wedge plate to move. The movement of the wedge plate further drives the connecting rod, thereby adjusting the position of the second crushing tooth, thereby accurately adjusting the material passing gap between the first crushing tooth and the second crushing tooth. In this way, even after a period of use, it can ensure that the crushed particle size of the aggregate always meets the requirements, greatly extending the service life of the equipment. The device not only realizes the effective crushing of aggregates and precise control of particle size, but also the feeding hopper has the function of adjusting the material passing gap to adapt to working requirements under different wear conditions, ensuring that the quality and particle size of concrete aggregates always meet the engineering requirements.

[0025] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.
[0026] like Figure 1-5 As shown, the technical solution adopted by the utility model is as follows: a recycled concrete aggregate hopper, comprising a hopper body 1, the hopper body 1 is conical, a plurality of first crushing teeth 2 are arranged in an array on the inner wall of the hopper body 1, and the hopper body 1 is arranged on a support plate 3 through a bracket;
[0027] A fixed plate 4 is provided on the top of the hopper body 1, a rotating assembly is provided on the fixed plate 4, a conical shell 5 located inside the hopper body 1 is installed on the rotating assembly, the conical shell 5 is narrow at the top and wide at the bottom, and an adjustment assembly is provided inside the conical shell 5, and a conical sleeve 6 is provided on the adjustment assembly;
[0028] A plurality of through holes are arranged in an array on the hopper body 1, and a connecting rod 7 is movably arranged inside the through holes. A wedge plate 8 fitting with the conical sleeve 6 is installed at one end of the connecting rod 7, and a second crushing tooth 9 is installed at the other end of the connecting rod 7. A spring 14 is sleeved on the connecting rod 7, and the spring 14 is located between the wedge plate 8 and the inner wall of the conical shell 5.
[0029] Its working principle is as follows: when people put concrete aggregate into the hopper body 1, the rotating assembly is started, and the conical shell 5 starts to rotate. This rotation action causes the second crushing tooth 9 to rotate as well, so that the aggregate located between the first crushing tooth 2 and the second crushing tooth 9 will be clamped and rubbed by the two, thereby achieving preliminary crushing. Since the hopper body 1 and the conical shell 5 are both designed to be conical, as the aggregate descends in the hopper, the space between the inner wall of the hopper body 1 and the outer side of the conical shell 5 gradually decreases, thereby further improving the degree of aggregate crushing and ensuring high-quality crushing effect. However, long-term use will cause the first crushing tooth 2 and the second crushing tooth 9 to gradually wear due to continuous extrusion and friction, resulting in a gradual increase in the material passing gap between them, which will affect the crushing particle size of the aggregate and make it less and less in line with the requirements. In order to solve this problem, we can use the adjustment assembly to adjust the position of the conical sleeve 6. When the conical sleeve 6 moves upward, it squeezes the wedge plate 8, causing the wedge plate 8 to move. The movement of the wedge plate 8 further drives the connecting rod 7, thereby adjusting the position of the second crushing tooth 9, thereby accurately adjusting the material passing gap between the first crushing tooth 2 and the second crushing tooth 9. In this way, even after a period of use, it can ensure that the crushed particle size of the aggregate always meets the requirements, greatly extending the service life of the equipment.
[0030] Among them, the feeding hopper body 1 is conical, which is wide at the top and narrow at the bottom. This setting can form an increasingly smaller material passing gap with the characteristics of the conical shell 5 that is narrow at the top and wide at the bottom, which can further improve the degree of aggregate crushing and ensure high-quality crushing effect.
[0031] At the same time, the elastic force of the spring 14 can prevent the centrifugal force from causing the connecting rod 7 to move during rotation.
[0032] At the same time, if Figure 5 As shown, the adjustment assembly includes a threaded rod 10 rotatably arranged inside the conical housing 5, the threaded rod 10 is threadedly connected to the conical sleeve 6, and the bottom of the threaded rod 10 passes through the conical housing 5 and is equipped with a rotating disk 15.
[0033] When people make adjustments, the rotating disk 15 drives the threaded rod 10 to rotate, and then the threaded rod 10 drives the conical sleeve 6 to move upward, thereby squeezing the wedge plate 8 to make adjustments.
[0034] In order to facilitate people to make adjustments, an opening and closing door 16 is provided on the hopper body 1. The opening and closing door 16 corresponds to the position of the rotating disk 15. By opening the opening and closing door 16, the rotating disk 15 can be operated, which is convenient for people to make adjustments.
[0035] At the same time, in order to ensure that the conical sleeve 6 does not rotate when moving upward, an anti-skid surface is provided on the wedge plate 8, and the conical sleeve 6 will not rotate but only move up and down due to the anti-skid surface.
[0036] like Figure 1 As shown, the rotating assembly includes a motor 11 fixedly mounted on a fixed plate 4, the output end of the motor 11 is connected to the conical shell 5, and the conical shell 5 is driven to rotate by the motor 11, thereby crushing the aggregate.
[0037] A collecting shell 12 for carrying aggregates inside the hopper body 1 is arranged at the bottom of the supporting plate 3. An inclined filter plate 13 is arranged inside the collecting shell 12. The filter plate 13 divides the collecting shell 12 into two collecting areas.
[0038] The crushed aggregate enters the collecting shell 12 and then is filtered by the filter plate 13 to classify the concrete materials that meet the requirements and the concrete materials that do not meet the requirements.
[0039] Two discharge ports are arranged at the bottom of the collecting shell 12, through which concrete materials that meet the requirements and concrete materials that do not meet the requirements can be collected, so as to facilitate subsequent use.
[0040] Support legs are provided at the bottom of the support plate 3, and the entire device is supported by the support legs.
[0041] The working principle of the utility model is as follows: when people put concrete aggregate into the hopper body 1, the rotating assembly is started, and the conical shell 5 starts to rotate. This rotation action causes the second crushing tooth 9 to rotate accordingly, so that the aggregate located between the first crushing tooth 2 and the second crushing tooth 9 will be clamped and rubbed by the two, thereby achieving preliminary crushing. Since the hopper body 1 and the conical shell 5 are both designed to be conical, as the aggregate descends in the hopper, the space between the inner wall of the hopper body 1 and the outer side of the conical shell 5 gradually decreases, thereby further improving the degree of aggregate crushing and ensuring a high-quality crushing effect. However, long-term use will cause the first crushing tooth 2 and the second crushing tooth 9 to gradually wear due to continuous extrusion and friction, resulting in a gradual increase in the material passing gap between them, which will affect the crushing particle size of the aggregate and make it less and less in line with the requirements. In order to solve this problem, we can use the adjustment assembly to adjust the position of the conical sleeve 6. When the conical sleeve 6 moves upward, it squeezes the wedge plate 8, causing the wedge plate 8 to move. The movement of the wedge plate 8 further drives the connecting rod 7, thereby adjusting the position of the second crushing tooth 9, thereby accurately adjusting the material passing gap between the first crushing tooth 2 and the second crushing tooth 9. In this way, even after a period of use, it can ensure that the crushed particle size of the aggregate always meets the requirements, greatly extending the service life of the equipment.
[0042] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
