Description

Technical Field

[0001] This invention relates to the field of cement product feeding technology, and more specifically, to an automatic cement product feeding device. Background Technology

[0002] Cement is a powdered hydraulic inorganic binder that forms a paste when mixed with water. It hardens in air or, even better, in water, and can firmly bind materials such as sand and stone together. The history of cement can be traced back to the mixture of lime and volcanic ash used by the ancient Romans in construction. This mixture is very similar to modern lime-volcanic ash cement. Concrete made by binding crushed stone with cement not only has high strength after hardening, but also resists erosion from fresh or salt water. For a long time, it has been widely used as an important binder in civil engineering, water conservancy, national defense and other projects.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The present invention will be further described below with reference to the embodiments.

[0056] Please see Figures 1-8 In one embodiment of this application, an automatic cement product feeding device is provided, comprising a frame 1, a plurality of movable wheels 3, a control box 2, a feeding box 4, and a docking cylinder. The plurality of movable wheels 3 are symmetrically arranged on the frame 1, the control box 2 is mounted on the frame 1, and the feeding box 4 and the docking cylinder are both mounted on the frame 1 and are connected to each other. The feeding box 4 is provided with a feed inlet 5. The device further comprises:

[0057] The material conveying auger 7 is movable within the feeding box 4;

[0058] The power unit is installed on the feeding box 4 and its output end is connected to the conveying auger 7;

[0059] A screening system, located between the feeding hopper 4 and the docking cylinder, is used for screening cement raw materials; and

[0060] The recycling system, installed on frame 1, is used to recycle the stones and cement blocks screened out by the screening system;

[0061] The screening system includes:

[0062] Screening box 8 is set on frame 1 and connects feeding box 4 and docking cylinder;

[0063] The screening execution module, located inside screening box 8, is used to perform the screening of cement raw materials; and

[0064] A power output module is installed on the screening box 8 and connected to the recycling system. When the screening execution module is working, it controls the operation of the recycling system through the power output module.

[0065] In one specific embodiment, the docking cylinder includes an upper docking cylinder 9 and a lower docking cylinder. The upper docking cylinder 9 is mounted on a frame 1, and the lower docking cylinder is slidably sleeved on the upper docking cylinder 9. An electric telescopic rod 15 is mounted on the frame 1, and the movable end of the electric telescopic rod 15 is connected to the lower docking cylinder. The lower docking cylinder has a conical structure. A cleaning module is provided between the upper docking cylinder 9 and the lower docking cylinder for cleaning the cement adhering to the inner wall of the lower docking cylinder.

[0066] In another specific embodiment, the cleaning module includes:

[0067] Mounting base 11 is set on feeding box 4. Several scraper strips 18 are arranged in the inner ring of the upper receiving cylinder. The scraper strips 18 and the lower receiving cylinder are fitted with a clearance.

[0068] The movable seat 16 is slidably mounted on the mounting platform on the lower cylinder, and the movable seat 16 is movably mounted on the mounting platform.

[0069] Push arm 17, a fixed rod 27 is provided on the lower docking cylinder, the fixed rod 27 is movably connected to the push arm 17 and the movable seat 16; and

[0070] The roller 12 is movably mounted on the mounting platform and slides in cooperation with the mounting base 11. The eccentric position of the roller 12 is movably connected to the drive arm 13 and the movable base 16.

[0071] It should be noted that the power element can be a stepper motor 6 or a servo motor. In this embodiment, the power element is preferably a stepper motor 6. The stepper motor 6 is mounted on the feeding box 4 and its output end is connected to the conveying auger 7. The specific model parameters of the stepper motor 6 can be selected according to the actual situation and are not specifically limited here.

[0072] In practical applications, the entire device is moved to the cement product production equipment location, and the docking cylinder is controlled to dock with the production equipment. During this process, the electric telescopic rod 15 is extended via the control box 2, thereby causing the lower receiving cylinder to move downward relative to the upper receiving cylinder. The lower receiving cylinder moves to the receiving port on the production equipment to achieve docking. During this process, the frictional resistance between the roller 12 and the mounting base 11 drives the roller 12 to rotate. When the roller 12 rotates, it drives the moving base 16 to reciprocate via the drive arm 13. Thus, under the action of the push arm 17, the lower receiving cylinder rotates relative to the upper receiving cylinder, thereby facilitating the docking. The scraper 18 cleans the inner wall of the material lower cylinder, and then the stepper motor 6 is controlled by the control box 2 to drive the conveying auger 7 to rotate. The operator feeds cement raw materials into the feed inlet 5. The cement raw materials enter the screening box 8 through the feeding box 4. The screening execution module is controlled by the control box 2 to screen out the stones and cement blocks in the cement raw materials and finally discharge them into the recycling system. The finally screened cement raw materials are discharged into the production equipment through the docking cylinder. At the same time as the screening execution module is working, the power output module can be controlled to work, thereby driving the recycling system to recycle the screened stones and cement blocks.

[0073] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5 In another preferred embodiment of this application, the screening execution module includes:

[0074] A screening tray 19 is movably set inside the screening box 8, and several screening chambers 20 are arranged around the screening tray 19.

[0075] A No. 1 screen 21 is movably installed in each screening chamber 20, and the No. 1 screen 21 and the screening chamber 20 are elastically connected.

[0076] An inner plate 22 is disposed inside the screening box 8 and located inside the screening plate 19. The inner plate 22 has a hollow structure and is provided with a discharge port 26 communicating with the recycling system.

[0077] A drive assembly is disposed between the inner disk 22 and the first screen 21. When the screening disk 19 rotates relative to the inner disk 22, the drive assembly controls the movement of the first screen 21.

[0078] In this embodiment, the driving component includes a driving disk 24 and a first connecting rod 25. The driving disk 24 is movably disposed on the screening disk 19 and its outer arm and inner disk 22 are slidably engaged. The first connecting rod 25 is movably connected between the eccentric position of the driving disk 24 and the first screen 21. The driving disk 24 is connected to the power output module, and the driving disk 24 controls the operation of the power output module when it moves.

[0079] It should be noted that in this embodiment, the position of the No. 1 screen 21 is not limited to the above-mentioned driving method of the No. 1 connecting rod 25 and the drive disk 24. It can also be replaced by a linear motor or an electric cylinder, which will not be listed here.

[0080] In practical applications, the conveying auger 7 feeds cement raw materials into the screening box 8. The control box 2 controls the rotation of the screening disc 19, which in turn drives the screening chamber 20 to rotate. The cement raw materials entering the screening box 8 fall into the screening chamber 20 and follow the movement of the screening disc 19. During this process, the frictional resistance between the drive disc 24 and the inner disc 22 drives the drive disc 24 to rotate. Under the action of the first connecting rod 25, the first screen 21 can reciprocate within the screening chamber 20, thereby screening the cement raw materials. When the screening chamber 20 moves to the set position, the stones and cement blocks left on the surface of the first screen 21 can be discharged into the inner disc 22 through the window 23 and finally discharged into the recycling system through the discharge port 26. Cement raw materials that meet the quality standards can be discharged into the production equipment through the receiving cylinder, completing the cement raw material feeding process.

[0081] Please see Figures 1-8 As another preferred embodiment of this application, the recycling system includes:

[0082] The recycling bin 30 is mounted on the frame 1 and connected to the discharge port 26;

[0083] Screen No. 2, 32, is placed inside recycling bin 30; and

[0084] The crushing module is located inside the recycling bin 30 and on one side of the second screen 32. It is used to crush the stones or cement blocks on the second screen 32.

[0085] In one specific case of this embodiment, the second screen 32 is arranged at an angle relative to the recycling bin 30.

[0086] In another specific embodiment, the crushing module includes a crushing roller 33, a slider 35, a roller arm 34, and a cylinder 31;

The power output module is connected to the cylinder 31, and the power output module controls the extension and retraction of the cylinder 31 when it is working.

[0088] It should be further noted that the power output module includes:

[0089] The transfer box 36 is movably mounted on the frame 1 and connected to the cylinder 31;

[0091] Piston 38 is movably disposed inside hollow tube 37, and piston 38 is movably connected to drive disc 24 at an eccentric position via second connecting rod 39.

[0092] It should be noted that the cylinder 31 in this embodiment is not limited to the mechanical structure described above, and can also be replaced by a fan or air pump, which will not be listed here.

[0093] In practical applications, the stones and cement blocks screened by the screening disc 19 can be discharged along the inner disc 22 and the discharge port 26 into the second screen 32 inside the recycling box 30. During the rotation of the drive disc 24, under the action of the second connecting rod 39, the piston 38 is driven to reciprocate along the hollow tube 37, thereby repeatedly squeezing the air in the hollow tube 37 into the cylinder 31, causing the cylinder 31 to continuously extend and retract, and driving the slider 35 to reciprocate along the recycling box 30. Under the action of the roller arm 34, the crushing roller 33 can be driven to reciprocate along the second screen 32, thereby crushing the stones and cement blocks, which facilitates subsequent recycling.
