DETAILED DESCRIPTION

[0025] The utility model will be further explained in detail below by combining with the drawings and through examples, the following examples are the explanation of the utility model and the utility model is not limited to the following examples.

[0026] Example: see Figure 1 Figure 4 In this embodiment, a sand preparation and screening integrated machine for preparing concrete poles is provided, which specifically comprises a rack 1, a crushing unit 2, a screening unit 3 and a conveying unit 4. The crushing unit 2, the screening unit 3 and the conveying unit 4 are installed on the rack 1 from top to bottom. The crushing unit 2 comprises a hopper 21, and the hopper 21 is provided with a crushing component 22. The screening unit 3 is arranged obliquely below the crushing unit 2. The screening unit 3 is provided with a screen 33 and a vibrating component 35. The obliquely downward end of the screening unit 3 is provided with a first discharge outlet 31. The screening unit 3 is provided with a second discharge outlet 32 below the screen 33. The conveying unit 4 is arranged obliquely below the second discharge outlet 32.

[0027] ​In the embodiment, the rack 1 is designed to be installed with the crushing unit 2, the screening unit 3 and the conveying unit 4 from top to bottom, which not only saves space, but also facilitates the monitoring and maintenance of the operator. The crushing unit 2 crushes large stones into sand through the crushing components 22 in the hopper 21, and the crushed sand falls into the screening unit 3 from the hopper 21. The crushed sand is screened through the screening unit 3, and the corresponding screen 33 is selected according to the particle size of the sand. The coarse sand that does not pass through the screen 33 is output from the first discharge port 31 on the side, and the fine sand screened by the screen 33 falls into the conveying unit 4 from the second discharge port 32 below. The screening unit 3 is inclined below the crushing unit 2, which accelerates the screening process by gravity, and the use of the screen 33 and the vibration component 35 improves the screening efficiency. In the embodiment, the conveying unit 4 is inclined below the second discharge port 32, and the fine sand screened by the conveying unit 4 is directly conveyed to the transport vehicle or transferred to the equipment used in the next process. This design not only simplifies the conveying path of the material, but also reduces the loss of the material during the transfer process.

[0028] The crushing and screening of the sand can be continuously completed in the same device through the integrated design of the crushing unit 2 and the screening unit 3, which avoids the problem of transferring the sand between different devices in traditional equipment, reduces the operation steps, and improves the work efficiency. Compared with the traditional sand making and screening equipment which usually needs to occupy independent space, the present device combines the two, effectively reduces the occupation of the production site, improves the space utilization, and reduces the dust generated during the transfer of the sand between the devices.

[0029] The screening unit 3 is connected to the rack 1 through two groups of elastic connecting components 34, as shown in Figure 5 The elastic connecting component 34 includes a support rod 341, and the end of the support rod 341 is sleeved with a support seat 342. The bottom of the support seat 342 is connected to the rack 1 through a spring 343. The use of the spring 343 as the elastic connecting component 34 can effectively absorb the vibration generated by the screening unit 3 during the working process, reduce the influence of the vibration on the rack 1, thereby reducing the noise and providing a more stable working environment. The screening unit 3 of the present device reduces vibration and noise, improves the working environment, and meets the high-efficiency and environmental protection requirements of modern industrial production.

[0030] In the embodiment, the crushing unit 2 includes a hopper 21, and the hopper 21 is provided with crushing components 22. As shown in Figure 3The crushing component 22 comprises a first crushing wheel 221 and a second crushing wheel 222, the first crushing wheel 221 is connected to the crushing motor 223, and the first crushing wheel 221 is in transmission connection with the second crushing wheel 222 through the gear transmission mechanism 5. The gear transmission mechanism 5 is designed with gears of different teeth to ensure that the first crushing wheel 221 and the second crushing wheel 222 can work efficiently and cooperatively to achieve efficient crushing of large stone materials. Specifically, the first crushing wheel 221 is provided with a first gear 51 with fewer teeth on the shaft, and the second crushing wheel 222 is provided with a second gear 52 with more teeth on the shaft. Through this design, the first crushing wheel 221 rotates at high speed under the drive of the crushing motor 223, driving the second crushing wheel 222 to crush the sand material at low speed but with greater torque, thereby achieving efficient crushing effect.

[0031] Referring to Figure 6 The feeding unit 4 comprises a first roller 43, a second roller 44 and a conveying belt 45. The first roller 43 is rotationally arranged at the discharging end 42 of the feeding unit 4, and the second roller 44 is rotationally arranged at the feeding end 41 below the feeding unit 4. The two ends of the conveying belt 45 are respectively sleeved on the first roller 43 and the second roller 44, and the first roller 43 is connected to the feeding motor 46 which drives the rotation of the first roller 43. A plurality of groups of limiting rollers 47 are arranged below the conveying belt 45, and each group of limiting rollers 47 is arranged in a V shape and in contact with the lower surface of the conveying belt 45. The limiting rollers 47 not only effectively prevent the conveying belt 45 from deviating from the track, but also make the cross section of the sand material supported by the conveying belt 45 in a circular arc shape, ensuring the stability of sand material conveying.

[0032] Referring to Figure 4 The vibrating component 35 comprises a vibrating rod 351 and a vibrating motor 353. The vibrating rod 351 is rotationally connected to the shell of the screening unit 3 and is provided with a pair of eccentric wheels 352 at both ends. The vibrating motor 353 drives the rotation of the vibrating rod 351 through the belt transmission mechanism 6. The belt transmission mechanism 6 comprises a first pulley 61, a second pulley 62 and a belt 63. The first pulley 61 is connected to the vibrating motor 353, the second pulley 62 is connected to the eccentric wheel 352, and the two ends of the belt 63 are respectively sleeved on the first pulley 61 and the second pulley 62. Through the drive of the vibrating motor 353, the first pulley 61 drives the rotation of the belt 63, thereby driving the rotation of the second pulley 62 and the eccentric wheel 352 connected thereto, and further driving the vibration of the vibrating rod 351. Through the design of the vibrating component 35, the screening unit 3 can produce effective vibration during operation, improving the screening efficiency.

[0033] The hopper 21 comprises an upper inlet 211 and a lower outlet 212, the inlet 211 is gradually expanded from bottom to top, and the outlet 212 is provided with a baffle 213. The hopper 21 comprises an upper inlet 211 and a lower outlet 212, the inlet 211 is gradually expanded from bottom to top, and the outlet 212 is provided with a baffle 213. The gradually expanded design of the inlet 211 is beneficial to the smooth entry of large stone materials into the interior of the hopper 21, and avoids the blockage of stone materials during the feeding process. Through the gradually expanded design of the inlet 211, the hopper 21 can accommodate more stone materials and ensure that these stone materials can smoothly enter the crushing part 22 area for crushing treatment. Referring to Figure 7 The outlet 212 is slidably provided with the baffle 213, the baffle 213 can be moved according to needs, the size of the outlet 212 is adjusted, and then the discharging speed and the discharging amount are controlled. This design can effectively control the outflow speed of the crushed sand materials, and ensure that the sand materials can uniformly enter the screening unit 3 for screening operation. At the same time, the setting of the baffle 213 can also prevent the splashing materials generated during the crushing process, and ensure a safe operation environment.
