Description

Technical Field

[0001] The utility model belongs to the technical field of concrete processing, and in particular relates to a dust reduction type concrete raw material conveying device. Background Art

[0002] With the development of society, the use of concrete is increasing. Gravel and sand are the basic raw materials for making concrete, but these raw materials are mixed with dust, which is easy to cause dust to be raised during transportation and pollute the working environment. Therefore, transportation equipment with dust reduction function is needed for transportation. At present, some technologies have appeared on the market that can remove dust from raw materials during transportation.

[0003] For example, patent application number CN202220402707.5 discloses a dust-reducing concrete raw material conveying device, comprising: a frame, which is arranged as a rectangular frame structure, two electric lifting rods are arranged on both sides of the frame, and the upper end of the electric lifting rod is connected to the lower end of the protection plate, and a water distribution tank is placed inside the upper end of the protection plate; a suction fan, which is installed at the upper end of the frame, a filter is arranged at the upper end of the frame, and a U-shaped cavity structure is arranged inside the frame, and both sides of the inner wall of the frame are snap-connected with collecting plates. The dust-reducing concrete raw material conveying device protects the concrete raw materials on the transport crawler through the frame inside the device together with the protective plate and the collecting trough. When in use, the motor drives the connecting pipe to rotate and pull the transport crawler for conveying, so that no external dust or stones and other objects will be mixed into the concrete raw materials on the transport crawler and transported to the production device, thereby improving the overall purity of the concrete raw materials.

[0004] In the prior art, the dust of the raw materials is collected during transportation to prevent it from being blown away, and external dirt can be prevented from entering, thereby avoiding pollution of the working environment to a certain extent. However, there are still many deficiencies during use: first, in the prior art, only the floating dust is collected during transportation, but there is still a large amount of dust in the raw materials, and a large amount of dust will still be raised when the raw materials are discharged to other devices, which will still cause pollution to the working environment and result in poor use effect; second, the existing protective frames are mostly fixed, and the protection length cannot be quickly adjusted and is not easy to maintain, resulting in high cost of use. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the utility model provides a dust-reducing concrete raw material conveying device. The utility model, through the arrangement of a dust-reducing box and a dust-reducing assembly, can shake off most of the dust adhering to the surface of the raw materials in the early stage of transportation and collect and process the dust, so that a large amount of dust will not be raised when the raw materials are discharged, thus avoiding pollution of the working environment. With the adjustable sliding frame and dust-proof cloth, the protective length of the conveyor belt can be quickly adjusted, which is convenient for maintenance and reduces the use cost.

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0032] Embodiment 1:

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, a dust reduction type concrete raw material conveying device includes a frame 12, a conveyor belt 16, a conveyor belt 16 with two sides extending outward in a trumpet shape is provided on the end surface of the frame 12 for transmission, two slide grooves 39 are symmetrically provided on both sides of the conveyor belt 16 on the end surface of the frame 12, a plurality of sliding frames 13 are slidably provided on the two slide grooves 39, a dustproof cloth 14 is connected between the plurality of sliding frames 13, a dust reduction box 10 is provided on the end surface of the frame 12 above the conveyor belt 16, and a dust reduction component is provided in the dust reduction box 10;

[0034] The dust reduction assembly includes a plurality of support plates 18 which are arranged in an up-and-down staggered manner in the dust reduction box 10. A vibrator 25 is arranged on one side of each support plate 18 on the inner wall of the dust reduction box 10. A plurality of guide grooves 22 are evenly arranged along a straight line direction on the end surface of the support plate 18. Each guide groove 22 is provided with a plurality of conical teeth 28. A dust suction seat 19 is arranged on the inner wall of the dust reduction box 10 between two staggered support plates 18.

[0035] The dust reduction box 10 will first remove dust from the concrete raw materials. The raw materials with most of the dust removed will fall onto the conveyor belt 16 and then be sent out. The multiple sliding frames 13 arranged on the conveyor belt 16 can be pulled according to the length of the conveyor belt 16, thereby pulling the dustproof cloth 14 to cover the outside of the conveyor belt 16, thereby preventing external dust from entering and the remaining dust from being blown out.

[0036] Each pallet 18 is tilted downward, and each pallet 18 will guide the material downward to the pallet 18 of the next layer. During the flow of the material, the vibrator 25 will vibrate the pallet 18, thereby shaking the material to shake the dust outward, and the dust suction seat 19 will extract the shaken dust to ensure that the raw materials discharged outward do not contain a large amount of dust.

[0037] like Figure 4 and Figure 5 As shown, a feed port 11 is provided on one side of the top of the dust reduction box 10 , and a discharge port 26 is provided on one side of the bottom of the dust reduction box 10 .

[0038] The feed port 11 is used for the entry of raw materials, and the discharge port 26 is used for discharging the raw materials onto the conveyor belt 16 .

[0039] Further, such as Figure 4 , Figure 5 and Figure 6 As shown, the dust reduction assembly also includes a rotating shaft 29 arranged in one end of the support plate 18, and the rotating shaft 29 is rotatably arranged on the inner wall of the dust reduction box 10. A sliding frame 30 is arranged at the output end of each vibrator 25 below the rotating shaft 29, and a sliding rod 31 is slidably arranged in the sliding frame 30. A rotating seat 32 is connected to the outer end surface of the sliding rod 31, and one end of the rotating seat 32 is arranged at the bottom of the support plate 18, and a spring 33 is connected to one end of the sliding rod 31 in the sliding frame 30.

[0040] The rotating shaft 29 set at one end of the support plate 18 allows the support plate 18 to rotate in the dust suppression box 10. The setting of the sliding frame 30 and the sliding rod 31 allows the support plate 18 to be tilted and swung at the same time, and the setting of the spring 33 can enhance the vibration effect of the vibrator 25.

[0041] Further, such as Figure 4 and Figure 5 As shown, the dust reduction assembly also includes a first spray seat 23 arranged on the inner wall of the dust reduction box 10 on one side of the discharge port 26, a plurality of first spray ports 24 are arranged on the end face of the first spray seat 23, and a water storage tank 15 is arranged on the top of the dust reduction box 10 above the first spray seat 23.

[0042] The first spray seat 23 and the first spray port 24 spray water mist when the material is discharged downward onto the conveyor belt 16 through the discharge port 26, thereby performing the final dust reduction treatment.

[0043] like Figure 4 As shown, a dust storage box 17 is provided at the bottom of the frame 12 below the dust suction seat 19 .

[0044] The dust storage box 17 is used to collect the dust adsorbed by the plurality of dust suction seats 19, so as to facilitate cleaning by operators.

[0045] like Figure 4 , Figure 8 , Fig. 9 and Fig.10 As shown, transmission cylinders 20 with trumpet-shaped ends are arranged on the frame 12 on both sides of the conveyor belt 16, and two support plates 44 are symmetrically arranged in the frame 12 between the two transmission cylinders 20. A plurality of support wheels 43 that contact the two sides of the conveyor belt 16 are evenly arranged on the end faces of the support plates 44 in a straight line direction.

[0046] The two transmission cylinders 20 with trumpet-shaped ends will stretch and deform the conveyor belt 16, so that the two sides of the conveyor belt 16 are opened and tilted outward, so that the materials falling onto the conveyor belt 16 will not flow to the sides and the dust can be suppressed from rising. The two support plates 44 and the support wheels 43 can make the area on the upper end of the conveyor belt 16 that supports the raw materials always open and tilted outward, so as to support the conveyor belt 16.

[0047] Further, such as Fig. 9 As shown, a plurality of connecting holes 27 are provided on the end surface of the conveyor belt 16 , a guide plate 21 inclined toward both sides is provided in the middle of the conveyor belt 16 , and a sewage outlet 41 is provided on the frame 12 at one inclined end of the guide plate 21 .

[0048] The plurality of connecting holes 27 can allow the excess water sprayed on the raw material during the dust reduction process of the first spray seat 23 to drip downward onto the guide plate 21, and finally be discharged outward from the guide plate 21 through the drain port 41, thereby avoiding a large amount of water in the raw material.

[0049] In this embodiment, when the raw materials need to be transported, the staff starts the device and then pours the materials into the device through the feed port 11.

[0050] The raw materials poured inward through the feed port 11 will first fall onto the top support plate 18. During this process, the raw materials that fall onto the support plate 18 will press the support plate 18 and rotate downward with the rotating shaft 29, so that the sliding rod 31 connected to the bottom of the support plate 18 through the rotating seat 32 retracts inward into the sliding frame 30, so that the spring 33 in the sliding frame 30 is stressed. At this time, the spring 33 will begin to vibrate, so that the support plate 18 can be vibrated when the vibrator 25 is not fully started. Subsequently, the vibrator 25 will be started, and the output end of the vibrator 25 will vibrate the spring 33 and the sliding rod 31, thereby vibrating the support plate 18, so that the raw materials that fall onto the support plate 18 can be continuously shaken during the downward flow, so that the dust is dispersed outward.

[0051] During the process of the pallet 18 shaking and discharging materials, the raw materials that fall onto the pallet 18 will also fall into the guide groove 22. The multiple conical teeth 28 in the guide groove 22 will temporarily block the flowing raw materials and reduce the flow speed of the raw materials, so that the raw materials can be fully shaken on each layer of the pallet 18.

[0052] When multiple pallets 18 begin to shake, multiple dust suction seats 19 will also suck away the dust shaken out and floating in the dust reduction box 10 through the pipe mouth, and then store it in the dust storage box 17 for preservation, so as to facilitate cleaning by the staff. When the raw material passes through the bottom pallet 18 and is ready to be discharged outward through the discharge port 26, the first spray seat 23 will also be started. The first spray seat 23 will spray water mist through multiple first spray ports 24, thereby performing the final dust reduction treatment on the raw material that has been shaken multiple times, so that the dust that has not been completely shaken off will not be blown outward when it is discharged outward by the conveyor belt 16 on the raw material.

[0053] When the raw materials fall onto the conveyor belt 16, the transmission cylinder 20 will start, and the transmission cylinder 20 will drive the conveyor belt 16 to move to one side, so as to transport it outward. During the transportation process, multiple sliding frames 13 and the connected dust-proof cloth 14 can prevent external dust from entering the conveyor belt 16. The outward expansion of both sides of the conveyor belt 16 can also prevent the raw materials from falling to the outside.

[0054] During the conveying process of the conveyor belt 16 , the plurality of connecting holes 27 on the conveyor belt 16 will allow the excess moisture sticking to the raw materials during dust reduction to drip downward onto the guide plate 21 , and finally be discharged to the outside through the sewage outlet 41 .

[0055] Embodiment 2:

[0056] like Figure 4 , Figure 6 and Figure 7 As shown, a dust reduction type concrete raw material conveying device, the dust reduction component also includes a plurality of rotating rods 34 uniformly rotated along a linear direction and arranged on the end face of a support plate 18, each rotating rod 34 end face is provided with a connecting disk 35, an annular plate 37 is provided on the end face of the connecting disk 35, a plurality of elastic arc rods 36 bent outwardly are uniformly arranged along a circumferential direction on the end face of the connecting disk 35 in the annular plate 37, and an arc-shaped convex surface 38 is provided on the connecting disk 35 between the plurality of elastic arc rods 36.

[0057] As a further embodiment, when the raw material flows downward on the support plate 18, although part of the raw material is temporarily blocked by the conical teeth 28 in the guide groove 22, so that the raw material can be fully vibrated, if the conical teeth 28 are all set on the end face of the support plate 18, it will lead to reduced efficiency. Therefore, the guide grooves 22 are arranged at intervals, and the rotating rods 34 and the annular plates 37 arranged between the multiple guide grooves 22 will contact the flowing raw material during the downward flow of the raw material. The outside of the annular plate 37 is provided with multiple convex strips for increasing friction and contact. The flowing raw material will drive the annular plate 37 to rotate at different amplitudes, thereby driving multiple elastic arc rods 36 to rotate. The elastic arc rods 36 are made of elastic material. The multiple elastic arc rods 36 will move the flowing raw material to make it further shake, so that the support plate 18 can ensure the rapid flow of the raw material while allowing the raw material to further clean up the surface dust. In this relationship, the arc convex surface 38 on the end face of the connecting plate 35 can play a guiding role when the raw material falls into the annular plate 37, which is convenient for the discharge of the raw material and will not accumulate in the annular plate 37.

[0058] Embodiment three:

[0059] like Figure 8 As shown, a dust reduction type concrete raw material conveying device is provided, wherein a second spray seat 40 is provided in each sliding frame 13, and a plurality of second spray ports 42 are provided on the bottom end surface of the second spray seat 40.

[0060] As a further embodiment, during the process of conveying raw materials on the conveyor belt 16, if dust is still blown outward, the second spray seat 40 can be started, and then water is atomized and sprayed on the conveyor belt 16 through multiple second spray ports 42, so that the raw materials on the conveyor belt 16 can be dust-reduced.

[0061] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component.
