Description

Technical Field

[0001] This utility model belongs to the field of conveyor technology, and in particular relates to a sand and gravel conveying device. Background Technology

[0002] Belt conveyors are used for transporting sand and gravel. However, with existing belt conveyors, the amount of sand and gravel fed onto the conveyor belt is difficult to control, resulting in some sand and gravel accumulating too high and being unevenly distributed.

[0003] Chinese utility model patent CN221234831 U discloses a pneumatic sand and gravel conveyor, including a conveyor body. A leveling mechanism is installed on the top of the conveyor body, and a controller is mounted on the front of the conveyor body. A power plug is fixedly connected to the front of the conveyor body near the controller. The leveling mechanism includes support plates fixedly connected to the front and back of the conveyor body. A fixing plate is fixedly connected to the top of the support plates, and an electric slide rail is fixedly connected inside the fixing plate. A sliding table is installed on the outer wall of the electric slide rail. This device, with its leveling mechanism, can flatten accumulated sand and gravel, resulting in a more uniform distribution of sand and gravel on the conveyor belt. However, during the leveling process, sand and gravel may scatter outwards from both sides of the conveyor belt, causing material loss. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a sand and gravel conveying device. By installing a quantity control component inside the sand and gravel feeding box, the amount of sand and gravel material fed from the discharge port to the conveyor belt below can be controlled, thus avoiding the situation where the sand and gravel on the conveyor belt accumulates too high or is unevenly distributed due to the difficulty in controlling the amount fed.

[0005] In view of this, the present invention provides a sand and gravel conveying device, including a conveying assembly. A sand and gravel feeding box is mounted on the conveying assembly. The bottom of the sand and gravel feeding box has a discharge port aligned with the conveyor belt below. The sand and gravel feeding box has a feeding port. A quantity control component is installed inside the box. The quantity control component includes two symmetrically arranged guide plates. Both guide plates are connected to a driving component. A material drop channel can be formed between the two guide plates. The driving component can drive the guide plates to move to change the cross-sectional area of ​​the material drop channel to control the material delivery amount.

[0006] In this technical solution, by setting a quantity control component inside the sand and gravel feeding box, the amount of sand and gravel material fed from the discharge port to the conveyor belt below can be controlled, thus avoiding the sand and gravel on the conveyor belt from being piled up too high and unevenly distributed due to the difficulty in controlling the feeding amount.

[0007] In the above technical solution, the driving component is a first cylinder, one end of the first cylinder is hinged to the bottom of the sand and gravel feeding box, the output end of the first cylinder is hinged to the bottom of the guide plate, and one end of the guide plate is rotatably connected to the side wall of the sand and gravel feeding box.

[0008] In this technical solution, one side of the guide plate is rotatably connected to the side wall of the sand and gravel discharge box. The two ends of the guide plate perpendicular to the aforementioned connecting side wall are in contact with the inner side wall of the sand and gravel discharge box. To prevent wear, a rubber strip can be installed on the contact side of the guide plate. The guide plate is rotated by the drive component, thereby controlling the cross-sectional area of ​​the discharge channel to control the discharge amount of sand and gravel materials.

[0009] In the above technical solution, further, when the two guide plates are in a horizontal state under the drive of the driving component, the ends of the two guide plates abut against each other, and the material discharge channel is completely closed.

[0010] In this technical solution, when the two guide plates are in a horizontal state under the drive of the driving component, the two guide plates can close the material drop channel, and can stop the continued feeding of sand and gravel materials in time when the conveying device encounters an emergency.

[0011] In the above technical solution, a dispersion component is further provided above the quantity control component, which can disperse the sand and gravel material that is fed into the sand and gravel feed box from the top feed port.

[0012] In this technical solution, when the sand and gravel flow rate is large, clumping may occur, and direct falling into the material discharge channel may cause blockage. The dispersion component can effectively disperse the material, reduce the risk of blockage, and prevent large pieces of material or concentrated piles of sand and gravel from impacting and wearing the conveyor belt and the equipment below, thus extending the service life of the equipment.

[0013] In the above technical solution, the evenly dispersing component further includes two horizontally rotating rollers arranged in the sand and gravel feeding box. A dispersing roller is arranged on the circumference of the rotating roller and extends along the length of the rotating roller. The rotating roller is connected to a transmission device, which can drive the rotating roller to rotate.

[0014] In the above technical solution, the transmission device further includes a transmission box fixedly connected to the sand and gravel feeding box. The rotating roller inside the sand and gravel feeding box rotates into the transmission box. The rotating roller is coaxially fixedly connected to a pulley inside the transmission box. The two pulleys are connected by a transmission belt. One rotating roller is rotatably mounted in the transmission box. The other rotating roller passes through the transmission box and is coaxially fixedly connected to the output end of the first motor. The first motor is fixedly mounted on a mounting base fixedly mounted on the outer wall of the transmission box.

[0015] In this technical solution, the conveying device can also be replaced by other existing devices, such as two rotating rollers connected to a drive motor, which can drive the rotating rollers to rotate.

[0016] In the above technical solution, the dispersing rollers on the two rotating rollers are further arranged in an alternating manner along the length direction of the rotating rollers.

[0017] This technical solution enables more comprehensive dispersion, thereby improving the dispersion effect.

[0018] In the above technical solution, the conveying component further includes conveying rollers rotatably arranged on both sides of the support frame, a drive device is driven to one side of the conveying roller, and a conveyor belt is driven to both sides of the conveying rollers. The support frame is also arranged in an array of "concave" support members. The conveyor belt supported at the top of the support frame undergoes deformation with a lower middle and higher sides under the support of the support members.

[0019] In this technical solution, the conveyor belt at the top of the support frame deforms with a low center and high sides under the support of the top support member. This design can effectively prevent materials from slipping during the conveying process, improve the stability of the materials and the transmission efficiency. The drive device that drives the conveyor belt to move in the conveying component is existing technology and will not be described in detail.

[0020] In the above technical solution, the supporting component further includes a base plate fixedly connected to both sides and the top of the support frame. A connecting rod is connected between the base plates. An outer rod inclined towards the center is symmetrically connected to both sides of the connecting rod. A support ring is symmetrically arranged in the center of the connecting rod. A first support roller is horizontally arranged between the two support rings. A second support roller inclined towards the center is symmetrically arranged between the outer rods on both sides and the support rings.

[0021] In this technical solution, the first support roller, the second support roller, the support ring, and the outer rod can be connected in a fixed manner, preferably in a rotating manner. This not only supports the conveyor belt but also further reduces friction with the contact surface of the conveyor belt, thereby increasing the service life of the conveyor belt.

[0022] In the above technical solution, the bottom wall of the sand and gravel feeding box is inclined towards the discharge port, and the discharge port corresponds to the middle of the conveyor belt below.

[0023] In this technical solution, the bottom wall of the sand and gravel feeding box is inclined, which can prevent the sand and gravel materials from accumulating on the bottom wall and ensure timely discharge.

[0024] The beneficial effects of this utility model are:

[0025] 1. By installing a quantity control component inside the sand and gravel feeding box, the amount of sand and gravel material fed from the discharge port to the conveyor belt below can be controlled, thus avoiding the sand and gravel on the conveyor belt from being piled up too high or unevenly distributed due to the difficulty in controlling the feeding amount.

[0026] 2. A dispersion component is installed above the flow control component. The dispersion component can disperse the sand and gravel material that is fed into the sand and gravel discharge box from the top feed port. When the sand and gravel flow rate is large, there may be clumping. Directly falling into the discharge channel may cause blockage. The dispersion component can effectively disperse the material, reduce the risk of blockage, and prevent large pieces of material or concentrated piles of sand and gravel from impacting and wearing the conveyor belt and the equipment below, thus extending the service life of the equipment.

[0027] 3. The conveying assembly includes a support frame with conveying rollers rotatably mounted on both sides. One conveying roller is driven by a drive unit, and conveyor belts are driven by both conveying rollers. The support frame is also equipped with arrayed "concave" support members. The conveyor belt supported on the top of the support frame undergoes a deformation that is lower in the middle and higher on both sides under the support of the support members. This design can effectively prevent materials from slipping during the conveying process and improve the stability and transmission efficiency of the materials. Attached Figure Description

[0041] First embodiment:

[0042] like Figure 1-6 As shown, this embodiment provides a sand and gravel conveying device, including a conveying component 1. A sand and gravel feeding box 2 is mounted on the conveying component 1. The bottom of the sand and gravel feeding box 2 has a discharge port 3, which is aligned with the conveyor belt 4 below. The sand and gravel feeding box 2 has a feeding port 5. A quantity control component 6 is installed inside the box. The quantity control component 6 includes two symmetrically arranged guide plates 7. Both guide plates 7 are connected to a driving component 8. A material drop channel 9 can be formed between the two guide plates 7. The driving component 8 can drive the guide plates 7 to move to change the cross-sectional area of ​​the material drop channel 9 to control the material delivery amount.

[0043] By installing a quantity control component 6 inside the sand and gravel feeding box 2, the amount of sand and gravel material fed from the discharge port 3 to the conveyor belt 4 below can be controlled, thus avoiding the sand and gravel on the conveyor belt 4 from being piled up too high and unevenly distributed due to the difficulty in controlling the amount of material fed.

[0044] like Figure 3 As shown, the driving component 8 is a first cylinder. One end of the first cylinder is hinged to the bottom of the sand and gravel feeding box 2, the output end of the first cylinder is hinged to the bottom of the guide plate 7, and one end of the guide plate 7 is rotatably connected to the side wall of the sand and gravel feeding box 2.

[0045] One side of the guide plate 7 is rotatably connected to the side wall of the sand and gravel discharge box 2. The two ends of the guide plate 7 perpendicular to the side wall of the connection are in contact with the inner side wall of the sand and gravel discharge box 2. To prevent wear, a rubber strip can be installed on the contact side of the guide plate 7. The guide plate 7 is rotated by the drive component 8, thereby controlling the cross-sectional area of ​​the discharge channel 9 to control the discharge amount of sand and gravel materials.

[0046] When the two guide plates 7 are in a horizontal state under the drive of the drive component 8, the ends of the two guide plates 7 abut against each other, and the material discharge channel 9 is completely closed.

[0047] When the two guide plates 7 are in a horizontal state under the drive of the drive component 8, the two guide plates 7 can close the material drop channel 9, and can stop the continued feeding of sand and gravel materials in time when the conveying device encounters an emergency.

[0048] The bottom wall of the sand and gravel feeding box 2 is inclined towards the discharge port 3, which corresponds to the middle of the conveyor belt below. The inclined bottom wall of the sand and gravel feeding box 2 can prevent sand and gravel materials from accumulating on the bottom wall and ensure timely discharge.

[0049] Second embodiment:

[0050] This embodiment provides a sand and gravel conveying device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0051] like Figures 3-5 As shown, a dispersion component 10 is provided above the quantity control component 6. The dispersion component 10 can disperse the sand and gravel material that is fed into the sand and gravel feed box 2 from the top feed port 5.

[0052] When the flow rate of sand and gravel is large, clumping may occur, and direct falling into the material discharge channel 9 may cause blockage. The dispersion component 10 can effectively disperse the material, reduce the risk of blockage, and prevent large pieces of material or concentrated piles of sand and gravel from impacting and wearing the conveyor belt and the equipment below, thus extending the service life of the equipment.

[0053] The uniform dispersion component 10 includes two horizontally rotating rollers 12 arranged in the sand and gravel feeding box 2. A dispersing roller 17 is arranged on the circumference of the rotating roller 12 and extends along the length of the rotating roller 12. The rotating roller 12 is connected to a transmission device, which can drive the rotating roller 12 to rotate.

[0054] like Figure 5 As shown, the transmission device includes a transmission box 11 fixedly connected to the sand and gravel feeding box 2. The rotating roller 12 inside the sand and gravel feeding box 2 rotates into the transmission box 11. The rotating roller 12 is coaxially fixedly connected to a pulley 13 inside the transmission box 11. The two pulleys 13 are connected by a transmission belt 14. One rotating roller 12 is rotatably mounted on the transmission box 11. The other rotating roller 12 passes through the transmission box 11 and is coaxially fixedly connected to the output end of the first motor 15. The first motor 15 is fixedly mounted on a mounting base 16 fixedly mounted on the outer wall of the transmission box 11.

[0055] The conveying device can also be replaced by other existing devices, such as two rotating rollers 12 connected to a drive motor, which can drive the rotating rollers 12 to rotate.

[0056] like Figure 4 As shown, the dispersing rollers 17 on the two rotating rollers 12 are staggered along the length of the rotating rollers 12. This allows for more thorough dispersing, thereby improving the dispersing effect.

[0057] Third embodiment:

[0058] This embodiment provides a sand and gravel conveying device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0059] like Figure 1 and Figure 6 As shown, the conveying assembly 1 includes a support frame 21 with conveying rollers 18 rotatably arranged on both sides. One side of the conveying roller 18 is connected to a drive device 19, and the two sides of the conveying rollers 18 are connected to a conveyor belt 4. The support frame 21 is also arranged with concave support members 20. The conveyor belt 4 supported on the top of the support frame 21 undergoes deformation with a lower middle and higher sides under the support of the support members 20.

[0060] The conveyor belt at the top of the support frame 21 deforms with a low center and high sides under the support of the top support member 20. This design can effectively prevent materials from slipping during the conveying process and improve the stability and transmission efficiency of the materials. The drive device 19 that drives the conveyor belt 4 to move in the conveying assembly 1 is existing technology and will not be described in detail.

[0061] like Figure 6 As shown, the support member 20 includes a base plate 22 fixedly connected to the top of the support frame 21 on both sides. A connecting rod 23 is connected between the base plates 22. An outer rod 24 inclined towards the center is symmetrically connected to both sides of the connecting rod 23. A support ring 25 is symmetrically arranged in the center of the connecting rod 23. A first support roller 26 is horizontally arranged between the two support rings 25. A second support roller 27 inclined towards the center is symmetrically arranged between the outer rods 24 on both sides and the support rings 25.

[0062] The first support roller 26, the second support roller 27, the support ring 25, and the outer rod 24 can be connected in a fixed manner, preferably in a rotating manner, so as to support the conveyor belt 4 while further reducing the friction between the conveyor belt 4 and the contact surface and improving the service life of the conveyor belt 4.

[0063] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
