DETAILED DESCRIPTION
[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0024] Embodiment 1: A concrete raw material sorting device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, it includes a shell 1, a feed plate 2, a screen 3, a sleeve 4, a buffer spring 5, a guide rod 6, a moving block 11, a discharge plate 13, a controller 20 and a pushing component. The feed plate 2 is connected to the right side of the upper part of the shell 1, and the discharge plate 13 is fixed at the lower part of the shell 1. The feed plate 2 and the discharge plate 13 are both inclined. Slide grooves 12 are opened on the front and rear sides of the shell 1. The moving block 11 is symmetrically slidably connected between the two slide grooves 12. Guide rods 6 are fixed symmetrically on the front and rear of the moving block 11. Three screens 3 are slidably connected between the guide rods 6. The mesh sizes of the three screens 3 decrease from top to bottom. The sleeves 4 are connected to the connection between the bottom screen 3 and the top screen 3 and the guide rod 6. The sleeves 4 are also connected to the connection between the upper and lower side walls of the screen 3 and the guide rod 6. The screen 3 slides along the guide rod 6, and the sleeves 4 on the same side will cooperate with each other to expand and contract. A buffer spring 5 is connected between the top screen 3 and each guide rod 6, and a buffer spring 5 is connected between the four corners of the bottom screen 3 and the moving block 11 on the same side. Buffer springs 5 are connected between the four corners of the upper and lower walls of the middle screen 3 and the guide rod 6. The buffer springs 5 are all sleeved on the guide rod 6. Except for the buffer springs 5 connected to the moving block 11, the remaining buffer springs 5 are all located inside the sleeve 4 on the same side. A controller 20 is installed on the right side of the front of the outer shell 1, and a pushing component for pushing the screen 3 to move left and right is provided inside the outer shell 1.
[0025] like Figure 2 , Figure 4 and Figure 7 As shown, the driving component includes a motor 7, a turntable 8, a belt 9 and a moving rod 10. The motor 7 is installed on the right side of the shell 1, and the motor 7 is electrically connected to the controller 20. The turntable 8 is connected to the output shaft of the motor 7. The position on the left side of the motor 7 in the shell 1 is also rotatably connected to the turntable 8. The belt 9 is wound around the two turntables 8. The position on one side of the top of the left turntable 8 is rotatably connected to the moving rod 10. The left end of the moving rod 10 is rotatably connected to the moving block 11 on the right. The motor 7 drives the two turntables 8 to rotate, so that the moving rod 10 pushes the moving block 11 to move left and right, which can drive the screen 3 to move left and right to screen the concrete.
[0026] When screening the concrete raw materials, the controller 20 is operated to start the motor 7, and then the raw materials are poured onto the feed plate 2 gradually, so that the raw materials slide down along the feed plate 2 and fall onto the screen 3. After the motor 7 is started, the output shaft rotates to drive the turntable 8 on the right to rotate, and then the turntable 8 on the left is driven to rotate through the belt 9, so that the turntable 8 on the left pushes the moving rod 10 to move left and right repeatedly, and the moving rod 10 drives the moving block 11 to move left and right along the slide 12, and then drives the three screens 3 to move left and right, so as to screen the raw materials. The mesh sizes on the three screens 3 decrease from top to bottom, and the raw materials can be triple screened. The larger particles of gravel in the raw materials will remain on the corresponding screens 3 The screen 3 will shake due to the falling of the raw materials, and the buffer spring 5 plays a buffering role. The fine sand screened on the screen 3 will slide out through the discharge plate 13. The staff continues to add raw materials to the feed plate 2 to continuously screen the raw materials. After a large number of large-particle gravel is screened out on the screen 3, the motor 7 can be paused, and the gravel screened out on the screen 3 can be pushed out and collected one by one to realize the sorting of concrete raw materials. The motor 7 is used as a power source to push the screen 3 to move left and right, which can make the screening of concrete raw materials more thorough, improve the quality of concrete processing, and also speed up the work efficiency of concrete sorting. After finishing the work, the motor 7 can be turned off by operating the controller 20.
[0027] Embodiment 2: Based on embodiment 1, Figure 4 and Figure 5 As shown, it also includes a torsion spring 16, a baffle 17, a push plate 14 and a push handle 1401. The positions on the rear wall of the shell 1 that are aligned with the three screens 3 are rotatably connected with the baffle 17, and two torsion springs 16 are connected between the left and right sides of the baffle 17 and the shell 1. The positions on the front side of the shell 1 that are aligned with the three screens 3 are slidably connected with the push plates 14. The three push plates 14 are respectively located above the three screens 3, and the front walls of the push plates 14 are fixed with push handles 1401. The push plates 14 can push the baffle 17 away by moving backward, and can push out the screened concrete stones on the screen 3.
[0028] like Figure 1 and Figure 6 As shown, it also includes a fan 18, a dustproof net 1801 and a ventilation duct 19. The fan 18 is installed on the left side of the top of the shell 1, and the fan 18 is electrically connected to the controller 20. The top of the shell 1 is connected to the ventilation duct 19 at the right side of the fan 18. The ventilation duct 19 is communicated with the fan 18. Part of the wind blown out by the fan 18 will enter the ventilation duct 19 and then blown downward from the ventilation duct 19. Two dustproof nets 1801 for filtering impurities are connected to the top of the fan 18.
[0029] When screening the concrete raw materials, the controller 20 can be operated to turn on the fan 18, and the fan 18 will blow the dust floating on the upper part of the shell 1 downward, and part of the wind blown by the fan 18 will enter the ventilation duct 19, and then blown downward from the ventilation duct 19, so that most of the dust will settle downward, avoiding that a lot of dust will float out of the shell 1 and affect the working environment. After stopping the screening work, the controller 20 is operated to pause the motor 7 and turn off the fan 18, so that the gravel on the screen 3 can be classified. To collect, use a long pole with a hook, hook the push handle 1401, and push the push plate 14 backward. The push plate 14 will push the baffle 17 to rotate and open, causing the torsion spring 16 to deform. The push plate 14 can be used to push the gravel on the screen 3 out for collection. After pushing it out, pull the long pole forward, hook the push handle 1401 and the push plate 14 and move them forward to reset. After the push plate 14 does not block the baffle 17, the baffle 17 will rotate in the opposite direction and close under the reset action of the torsion spring 16, which makes it convenient for the staff to quickly collect the gravel.
