Description

Technical Field

[0001] The utility model relates to the field of landscaping engineering, and particularly relates to a sand and gravel screening device for municipal landscaping engineering construction. Background Technique

[0002] Landscaping is to create a beautiful natural environment and recreation area by using engineering techniques and artistic means in a certain area, through transforming the terrain (or further building mountains, stacking stones, managing water), planting trees and flowers, building buildings and arranging garden paths, etc. Sometimes, stones are needed in landscaping work, and in some cases, these stones need to be screened to a similar size specification.

[0003] The prior art (publication number: CN 217616044 U) discloses a sand and gravel screening device for earthwork engineering construction, including a machine body and a collection device. A feeding port is arranged on the surface of the machine body. A screening barrel is rotatably connected to the inner wall of the machine body. A conveyor belt is arranged on one side of the machine body close to the screening barrel. The collection device is arranged on the surface of the machine body. The collection device includes a hollow sleeve and a collection box. The number of hollow sleeves is two. The hollow sleeves are fixedly connected to the lower surface of the machine body. The collection box is arranged below the hollow sleeves. Two connecting blocks are fixedly connected to the upper surface of the collection box. The connecting blocks are clamped with the inner walls of the hollow sleeves. A chute is arranged on the surface of the connecting block. A clamping rod is slidably connected to the inner wall of the chute. A clamping groove is arranged on the surface of the hollow sleeve;

[0004] Although the above patent is provided with a collection device, which can effectively reduce the phenomenon that the belt is contaminated with materials during transportation and reduce the waste of the materials contaminated on the belt, there are the following drawbacks. During use, the screened sand and gravel cannot be temporarily stored, and the production process may be interrupted. If it is necessary to wait for the downstream process to be ready to receive materials, this may lead to a decrease in production efficiency and time waste, and the falling position of the materials after screening cannot be changed, which may limit the flexibility of the production line. Therefore, further improvement is needed. For this reason, we propose a sand and gravel screening device for municipal landscaping engineering construction. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a sand and gravel screening device for municipal landscaping engineering construction, which can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A sand and gravel screening device for municipal landscaping engineering construction, including a workbench. Two feeding components are installed at the lower end of the workbench and are distributed left and right. Extension components are installed on both of the two feeding components. A temporary storage box is installed in the middle of the upper end of the workbench. Two support columns are installed at the front and rear of the upper end of the workbench respectively. Springs are installed at the upper ends of the four support columns, and a sieve plate is jointly installed at the upper ends of the four springs.

[0008] Preferably, the feeding component includes a U-shaped frame installed at the lower end of the workbench. A motor is installed at the lower end of the U-shaped frame. The output end of the motor movably penetrates the lower wall of the U-shaped frame and is fixedly connected to a first gear. The first gear is meshed with a second gear, and an electric valve pipe is fixedly sleeved inside the second gear.

[0009] Preferably, the extension component includes an electric cylinder installed on the electric valve pipe. The output end of the electric cylinder is fixedly connected to a ring. An extension pipe is fixedly sleeved inside the ring, and the extension pipe is movably sleeved on the outer surface of the electric valve pipe.

[0010] Preferably, a partition is installed inside the temporary storage box.

[0011] Preferably, a vibration motor is installed at the right lower part of the sieve plate, and the sieve plate is located above the temporary storage box.

[0012] Preferably, the upper end of the electric valve pipe movably penetrates into the temporary storage box.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By setting the temporary storage box, the screened sand and gravel can be temporarily stored. During use, the smaller screened sand and gravel fall into the right side of the temporary storage box through the sieve holes on the sieve plate, and the larger sand and gravel fall into the left side of the temporary storage box. Thus, the sand and gravel can be continuously screened without waiting for the downstream process to be ready to receive the materials, avoiding possible interruption in the production process, improving the production efficiency and reducing the waste of time.

[0015] 2. By setting the feeding component and the extension component, the feeding position can be changed. During use, according to the receiving position of the sand and gravel, control the motor to drive the first gear to rotate, the first gear drives the second gear to rotate, and the second gear then drives the electric valve pipe to rotate, thereby adjusting the feeding angle. Then, by controlling the electric cylinder to adjust the extending distance of the extension pipe through the ring, the feeding distance can be adjusted, so that the device receiving the sand and gravel can receive the screened sand and gravel at most positions, meeting the specific needs of different projects and customers and improving the flexibility of the production line.

The output end of the electric cylinder 91 is fixedly connected with a ring 92. An extension pipe 93 is fixedly sleeved inside the ring 92. The extension pipe 93 is movably sleeved on the outer surface of the electric valve pipe 85. During use, according to the receiving position of the sand and gravel, the motor 82 is controlled to drive the first gear 83 to rotate. The first gear 83 drives the second gear 84 to rotate. The second gear 84 drives the electric valve pipe 85 to rotate, so as to adjust the feeding angle. Then, by controlling the electric cylinder 91 to adjust the extending distance of the extension pipe 93 through the ring 92, the feeding distance can be adjusted, which can meet the specific requirements of different projects and customers, improve the flexibility of the production line, open the electric valve pipe 85 to discharge the screened sand to the receiving equipment, and transport it to the construction site of the landscaping project.

[0027] A partition 3 is installed inside the temporary storage box 2. The partition 3 is used to divide the internal storage space of the temporary storage box 2 into two parts.
