Description

Technical Field

[0001] The utility model relates to the technical field of garbage screening, in particular to a garbage screening device for construction waste. Background Art

[0002] Construction waste is a common type of garbage in daily life. It refers to construction waste generated in engineering projects due to human or natural reasons. With the acceleration of industrialization and urbanization, the construction industry has also developed rapidly, and the amount of construction waste generated has increased. In order to maximize the utilization of construction waste, it is usually necessary to use a garbage screening device to screen and process the construction waste before it can be used.

[0003] Most traditional screening methods require manual pouring of construction waste onto the screening plate for screening. In this way, the construction waste is often poured onto the screening plate and piled up at a fixed position, which makes it inconvenient to spread the construction waste on the screening plate, thereby affecting its screening efficiency. Therefore, in view of this, research and improvement are conducted on the existing structure to provide a garbage screening device for construction waste, in order to achieve a more practical purpose. Utility Model Content

[0004] The purpose of the utility model is to solve the problems in the background technology and to propose a garbage screening device for construction waste.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A garbage screening device for construction waste comprises a tilted screening bucket and a shaking feeding assembly placed above the screening bucket, a screening plate is fixedly mounted on the top of the screening bucket, and limit plates are fixedly mounted on both the front and rear sides of the top of the screening plate;

[0007] The shaking feeding assembly includes a dual-axis motor fixedly mounted on the side wall of the screening hopper, the upper driving end of the dual-axis motor is fixedly mounted with a first right-angle driving shaft, the first right-angle driving shaft is movably sleeved on a section of the outer wall away from the dual-axis motor and is provided with a first rectangular frame, the first rectangular frame is arranged horizontally, and the end of the first rectangular frame is fixedly mounted with a feeding hopper, the front and rear side walls of the feeding hopper are fixedly mounted with guide plates, and the two guide plates are respectively movably passed through the two limit plates.

[0008] Preferably, the lower driving end of the dual-axis motor is fixedly mounted with a second right-angle driving shaft, and the second right-angle driving shaft is movably sleeved with a second rectangular frame on a section of the outer wall away from the dual-axis motor. The second rectangular frame is arranged longitudinally, and a linkage plate is fixedly mounted on the end of the second rectangular frame, and the linkage plate movably passes through the outside of the screening bucket, and a ball block is fixedly mounted on the end of the linkage plate, and the surface of the ball block contacts a vibration plate fixedly mounted on the bottom of the screening plate.

[0009] Preferably, a material baffle plate is fixedly installed between the two limit plates, and the material baffle plate is placed at a higher position than the screening plate.

[0010] Preferably, two frames are fixedly mounted on the bottom of the screening bucket, and the two frames are symmetrically arranged.

[0011] Preferably, a sliding hole is provided on the outer side of the screening bucket, and the sliding hole is slidably connected to the linkage plate.

[0012] Compared with the existing technology, the advantages of the garbage screening device for construction waste provided by the utility model are:

[0013] 1. The upper end of the first right-angle drive shaft is driven by a dual-axis motor to move in a circular motion. Then, by using its back-and-forth movement within the first rectangular frame, the feed hopper can be pushed and pulled to move back and forth, thereby evenly pouring the construction waste in the feed hopper onto the surface of the screening plate to prevent all the construction waste from accumulating at a certain position on the screening plate, affecting the screening efficiency.

[0014] 2. When the dual-axis motor is started, the lower end of the second right-angle drive shaft will also move in a circular motion. Then, under the action of the second rectangular frame and the linkage plate, the ball block will reciprocate and strike the vibration plate, thereby driving the screening plate to vibrate, which helps to quickly spread the construction waste on the screening plate and improve the efficiency of garbage screening for construction waste.

[0015] To sum up, the utility model uses a reciprocating feed hopper to evenly pour the construction waste in the feed hopper onto the surface of the screening plate to avoid all the construction waste being accumulated at a certain position of the screening plate, affecting the screening efficiency. At the same time, the ball blocks are used to knock the vibration plate back and forth, which can also make the screening plate vibrate, helping to quickly spread the construction waste on the screening plate and improve the garbage screening efficiency of construction waste.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-Figure 3 A garbage screening device for construction waste comprises a tilted screening bucket 1 and a shaking feeding assembly placed above the screening bucket 1. A screening plate 2 is fixedly installed on the top of the screening bucket 1, and limit plates 3 are fixedly installed on the front and rear sides of the top of the screening plate 2. Two frames 4 are fixedly installed on the bottom of the screening bucket 1, and the two frames 4 are symmetrically arranged. A baffle plate 15 is fixedly installed between the two limit plates 3, and the baffle plate 15 is placed at the high position of the screening plate 2. The baffle plate 15 can prevent construction waste from sliding down from the lower end of the feed hopper 8 described below, so as to prevent construction waste from splashing out from the high position on the screening plate 2.

[0022] The shaking feeding assembly includes a double-axis motor 5 fixedly mounted on the side wall of the screening hopper 1, and the upper driving end of the double-axis motor 5 is fixedly mounted with a first right-angle driving shaft 6, and the first right-angle driving shaft 6 is movably sleeved with a first rectangular frame 7 on a section of the outer wall away from the double-axis motor 5. The first rectangular frame 7 is arranged horizontally, and the end of the first rectangular frame 7 is fixedly mounted with a feeding hopper 8. The front and rear side walls of the feeding hopper 8 are fixedly mounted with guide plates 9, and the two guide plates 9 are respectively movable through the two limit plates 3, which play a role in limiting the feeding hopper 8. The two guide plates 9 are respectively limited by the sliding of the two limit plates 3, so that the feeding hopper 8 can maintain longitudinal movement above the screening plate 2.

[0023] The lower driving end of the dual-axis motor 5 is fixedly installed with a second right-angle drive shaft 10, and the second right-angle drive shaft 10 is movably sleeved with a second rectangular frame 11 on a section of the outer wall away from the dual-axis motor 5. The second rectangular frame 11 is arranged longitudinally, and a linkage plate 12 is fixedly installed on the end of the second rectangular frame 11. A sliding hole is provided on the outside of the screening bucket 1, and the sliding hole is slidably connected to the linkage plate 12, and the linkage plate 12 is movable through the outside of the screening bucket 1, and a ball block 13 is fixedly installed on the end of the linkage plate 12. The surface of the ball block 13 contacts a vibration plate 14 fixedly installed on the bottom of the screening plate 2. Through the lateral back and forth movement of the ball block 13, the vibration plate 14 can be knocked back and forth, so that it drives the screening plate 2 to vibrate together, which helps to quickly spread the construction waste on the screening plate 2, improve the screening efficiency of construction waste, and at the same time, to a certain extent, effectively prevent the construction waste from blocking the screening holes on the surface of the screening plate 2.

[0024] The working principle of this utility model is:

[0025] When in use, the construction waste to be screened is poured into the feed hopper 8. At the same time, the dual-axis motor 5 is started to drive the first right-angle drive shaft 6 to move in a circular motion away from one end of the dual-axis motor 5. As a result, the feed hopper 8 can be pushed and pulled back and forth by pushing and pulling the first rectangular frame 7 back and forth, and the construction waste in the feed hopper 8 can be evenly poured onto the surface of the screening plate 2 to prevent all the construction waste from piling up at a certain position of the screening plate 2, which would affect the efficiency of garbage screening of the construction waste.

[0026] When the dual-axis motor 5 is started, the end of the second right-angle drive shaft 10 away from the dual-axis motor 5 will also move in a circular motion, and then by moving back and forth in the second rectangular frame 11, it can drive the linkage plate 12 to make the ball block 13 reciprocate and strike the vibration plate 14, thereby driving the screening plate 2 to vibrate, which helps to quickly spread the construction waste on the screening plate 2 and improve the efficiency of garbage screening of construction waste.

[0027] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
