DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0033] With reference to Figure 1 And Figure 2 An embodiment provided by the utility model: a building site is with environmental protection type gravel collection device, including support 1, support 1 top fixedly connected with shell one 2, shell one 2 inside rotatably connected with broken stick 10. The rotation of broken stick 10 is driven by motor one 8, and the output end of motor one 8 is connected with one end of broken stick 10, to ensure the effective crushing of gravel. Shell one 2 one side is provided with adjusting assembly, for adjusting the pressure between broken stick 10, to control the crushing degree of gravel;

[0034] Adjusting assembly includes frame 3, and frame 3 one side is fixedly connected on the outer wall of shell one 2, and frame 3 provides the support effect of adjusting assembly, to ensure the stability and precision of each component. Frame 3 inside fixedly connected with electric push rod 4, and the output end of electric push rod 4 is fixedly connected with connecting plate 5, and the sliding connection of connecting plate 5 makes push rod can move freely inside frame 3, to realize accurate pressure adjustment. Connecting plate 5 inside slidingly connected with limit post 6, and limit post 6 one end is fixedly connected with connecting block 7, and the role of limit post 6 is to ensure the sliding path of connecting plate 5, prevent excessive displacement, ensure the accuracy and stability of pressure adjustment, and connecting block 7 inside fixedly connected with motor one 8, and motor one 8 is connected with broken stick 10 through driving shaft, to ensure that the power output by motor is transmitted to broken stick 10, to realize the crushing of gravel. Limit post 6 outer wall is provided with spring 9, and one end of spring 9 is fixedly connected on one side of connecting plate 5, and the role of spring 9 is to exert a certain pressure on connecting block 7 through its elastic force, to adjust the pressure between broken stick 10, to affect the crushing effect. The other end of spring 9 is fixedly connected on the outer wall of connecting block 7, and when electric push rod 4 is retracted, spring 9 helps to adjust the pressure between broken stick 10 through its elastic force, to ensure the flexibility and adjustability during the crushing of gravel;

[0035] Specifically, when the size of the crushed sandstone needs to be adjusted, the output end of the electric push rod 4 is retracted, thereby driving the connecting plate 5 to move smoothly along a specified trajectory inside the limiting column 6. The limiting column 6 moves accordingly and further compresses the spring 9 outside the limiting column 6. At this time, the spring 9 generates tension due to compression, and this tension uniformly acts on the connecting block 7, thereby exerting pressure on the connecting block 7 and achieving precise adjustment of the pressure between the crushing rods 10. The connecting block 7 and the connecting plate 5 are stably limited by the limiting column 6, ensuring that the structure has sufficient stability and precision during the adjustment process. By adjusting the deformation degree of the spring 9, the pressure between the crushing rods 10 can be flexibly adjusted, thereby effectively controlling the degree of crushing of the sandstone. At the same time, the output end of the motor 8 drives the crushing rods 10 to rotate continuously, exerting a strong crushing effect on the sandstone, and ultimately achieving the effect of precisely adjusting the pressure between the crushing rods 10. This design not only improves the operational flexibility of the equipment, but also ensures the precision and efficiency of the sandstone crushing process.

[0036] With reference to Figures 3-5The bottom of the support 1 is fixedly connected with a shell two 11, the inside of the shell two 11 is fixedly connected with a grid 12, the grid 12 is used for screening and filtering large pieces of sand or sundries, preventing these sundries from entering the subsequent equipment or affecting the normal work of the equipment. The inside of the shell two 11 is also fixedly connected with a screen 16, the function of the screen 16 is to further screen the sand, separate the fine particles and the larger particles, so as to facilitate the subsequent processing. The inside of the shell two 11 is rotatably connected with a rotating shaft 14, the rotation of the rotating shaft 14 is driven by a motor two 13, the motor two 13 is connected with one end of the rotating shaft 14 through an output end, and provides power for the rotating shaft 14. The outer wall of the rotating shaft 14 is fixedly connected with an agitating rod 15, the agitating rod 15 rotates under the driving of the rotating shaft 14 and is slidingly connected in the inside of the screen 16. The rotating function of the agitating rod 15 is to prevent the screen 16 from being blocked, at the same time, the agitating rod 15 slightly stirs and screens the sand, ensures that the sand passing through the screen 16 is more uniform, avoids the sand with too large or too small particles from being stuck in the screen 16, and improves the screening efficiency. The bottom of the shell two 11 is fixedly connected with a conveying pipe 17, the conveying pipe 17 is used for conveying the screened sand to the subsequent processing part. The inside of the conveying pipe 17 is rotatably connected with a propeller 20, the propeller 20 is used for pushing the sand to flow along the pipe and conveying it to the next stage. The top of the conveying pipe 17 is fixedly connected with a motor three 18, the output end of the motor three 18 is fixedly connected with a speed reducer 19, the speed reducer 19 is used for slowing down the rotating speed of the output end of the motor three 18, so as to ensure that the rotating speed of the propeller 20 is moderate. The input end of the speed reducer 19 is connected with the output end of the motor three 18, and the output end of the speed reducer 19 is connected with one end of the propeller 20. The power after speed reduction is transmitted to the propeller 20, so as to ensure that the propeller 20 operates at a proper rotating speed, avoids the leakage problem caused by the too fast rotation of the sand, and also ensures the stable discharging of the sand. Through this setting, the whole sand conveying and screening system can work efficiently and stably, and the effect of optimizing sand collection and conveying is achieved;

[0037] Specifically, the crushed sand is uniformly poured into the inside of the shell two 11 through the grid 12 arranged at the outlet, ensuring the smoothness and efficiency of the subsequent operation process. In the shell two 11, the output end of the motor two 13 drives the rotating shaft 14 to rotate at a stable speed, and the rotating shaft 14 further drives the connected stirring rod 15 to rotate.
