Description

Technical Field

[0001] The present invention relates to the technical field of sand and gravel conveying, and more particularly to a sand and gravel aggregate conveying device. Background Art

[0002] Sand and gravel aggregates are indispensable basic materials in the construction of infrastructure such as buildings, roads, and bridges. They are also one of the most widely used engineering materials. They are composed of crushed stone, gravel, and sand, and can serve as filling, skeleton, and strength.

[0003] The sand and gravel aggregates need to be transported to a designated placement point using conveying equipment for placement, so as to facilitate their organization and use. Traditional conveying devices usually use equipment with a conveyor belt for transportation. However, since the conveyor belt is made of elastic material, when in use, when there are too many sand and gravel aggregates on the conveyor belt, the conveyor belt will break, thereby losing the function of transporting the sand and gravel aggregates and affecting the progress of the project. When there are too many materials on the conveyor belt, the excess sand and gravel aggregates cannot be removed from the conveyor belt to ensure that the conveyor belt will not be damaged. Therefore, the present invention discloses a sand and gravel aggregate conveying device. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a sand and gravel aggregate conveying device.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 8 A sand and gravel aggregate conveying device includes two fixed frames 1, a driving assembly 2 is provided between the two fixed frames 1, and a conveyor belt 3 is provided outside the two driving assemblies 2; Two mobile racks 4 are slidably mounted on the upper side of the fixed rack 1 on one side, and baffles 401 are fixedly mounted on the upper ends of the mobile racks 4. A protective plate 402 is fixedly mounted between the two baffles 401, and a pushing assembly 5 is provided between the protective plates 402. The pushing assembly 5 pushes the sand and gravel aggregate on the conveyor belt 3; The pusher assembly 5 includes a rotating rod 501 rotatably mounted in the middle of the protective plate 402, a plurality of push rods 502 are fixedly mounted on the outer wall of the rotating rod 501, a collection box 101 is fixedly mounted on one end of the fixed frame 1, and a discharge port 403 is provided at a position corresponding to the baffle 401 and the collection box 101. The pusher assembly 5 also includes a gear 503 fixedly mounted on one end of the rotating rod 501, a mounting frame 102 is fixedly mounted on the upper end of the fixed frame 1, and a rack 103 is fixedly mounted on the lower end of the mounting frame 102 at a position corresponding to the gear 503, and the gear 503 is meshed with the rack 103 for transmission; The driving assembly 2 includes a driving motor 201 fixedly mounted on the mobile frame 4, a driving roller 202 fixedly mounted on the output end of the driving motor 201, the other end of the driving roller 202 is rotatably connected to the mobile frame 4, and the conveyor belt 3 is sleeved on the outside of the two driving rollers 202 and in frictional contact with the driving rollers 202.

[0022] By adopting the above technical solution, after the sand and gravel aggregates are put onto the conveyor belt 3, the conveyor belt 3 can drive the driving roller 202 to descend under the action of the gravity of the sand and gravel aggregates. The descent of the driving roller 202 can drive the mobile frame 4 to descend, and when the mobile frame 4 descends, it can drive the baffle 401 to descend. After the baffle 401 descends, it can drive the protective plate 402 and the rotating rod 501 rotatably connected to the protective plate 402 to descend. During the descent of the rotating rod 501, it can drive the push rod 502 and the gear 503 to descend. After the gear 503 descends to a certain extent, it can mesh with the rack 103, thereby rotating. When the gear 503 rotates, it can drive the rotating rod 50 1 rotates, and when the rotating rod 501 rotates, it can drive the push rod 502 on its outer wall to rotate. During the rotation of the rotating rod 501, part of the sand and gravel aggregate on the conveyor belt 3 can be pushed into the collection box 101 through the discharge port 403. When the sand and gravel aggregate are separated from the conveyor belt 3, the movable frame 4 can drive the baffle 401 and the driving roller 202 to rise under the elastic force of the support spring 105. During the rising process of the baffle 401, the protective plate 402 can drive the rotating rod 501 to rise. At this time, the gear 503 can rise with the rotating rod 501, thereby rotating in the opposite direction. After the gear 503 rotates in the opposite direction, the rotating rod 501 can be rotated to the initial state.

[0023] A movable groove 104 is provided at the upper end of the fixed frame 1, and the movable frame 4 slides in cooperation with the movable groove 104, and a support spring 105 for supporting the movable frame 4 is fixedly installed at the lower end of the movable frame 4, and a first pressure sensor 106 is fixedly installed at the lower end of the support spring 105, and the first pressure sensor 106 is embedded in the inner wall of the lower end of the movable groove 104.

[0024] By adopting the above technical solution, during the descent of the mobile frame 4, since it is slidably installed inside the mobile groove 104, it can descend along the direction of the mobile groove 104, and when the mobile frame 4 descends, it can squeeze the support spring 105, causing the support spring 105 to contract and accumulate force. When the support spring 105 contracts, it can squeeze the first pressure sensor 106, thereby causing the pressure of the first pressure sensor 106 to change.

[0025] A support plate 107 is slidably mounted inside the collection box 101, and an electric push rod 108 is mounted on the lower side of the support plate 107. The upper end of the electric push rod 108 is in movable contact with the lower end of the support plate 107. A second pressure sensor 109 is embedded in the lower end of the support plate 107, and a pressure spring 110 is fixedly installed at the lower end of the second pressure sensor 109. The lower end of the pressure spring 110 is fixedly connected to the lower end of the inner wall of the collection box 101; The upper end of the support plate 107 is in an inclined structure, and a loading port 404 is provided at a position corresponding to the lowest point of the baffle 401 and the support plate 107. The sand and gravel aggregate in the collection box 101 falls back onto the conveyor belt 3 through the loading port 404, and the corner of the support plate 107 away from the loading port 404 is the highest point.

[0026] By adopting the above technical solution, the upper end of the electric push rod 108 is not fixedly connected to the lower end of the support plate 107. When the electric push rod 108 is extended, its upper end can squeeze the lower end of the support plate 107, so that the support plate 107 slides upward in the collection box 101. After the sand and gravel aggregate enters the collection box 101, the sand and gravel aggregate can roll to the side close to the loading port 404 under the action of the inclined part of the upper end of the support plate 107, and will be blocked in the collection box 101 by the baffle 401. When the support plate 107 rises, the sand and gravel aggregate can roll back to the conveyor belt 3 from the loading port 404 under the action of gravity, wherein the support plate 107 can descend and squeeze the pressure spring 110 after being squeezed by the sand and gravel aggregate, causing the pressure spring 110 to contract and accumulate force. After the pressure spring 110 contracts, it can squeeze the second pressure sensor 109, thereby causing the pressure of the second pressure sensor 109 to change.

[0027] A data processing module 111 is fixedly mounted on the fixed frame 1. The first pressure sensor 106 and the second pressure sensor 109 both transmit data to the data processing module 111. By using comparison operators provided by the programming language in the data processing module 111, the data processing module 111 compares the allowable load value of the conveyor belt 3 with the change value of the first pressure sensor 106 and calculates the difference. The data processing module 111 determines the size of the change value of the second pressure sensor 109 and compares the calculated difference with the change value of the second pressure sensor 109. A control module 112 is also fixedly mounted on the fixing frame 1 . The data processing module 111 sends a signal to the control module 112 . The control module 112 is used to control the extension and retraction of the electric push rod 108 .

[0028] By adopting the above technical solution, when the difference between the allowable load-bearing value of the conveyor belt 3 and the change value of the first pressure sensor 106 is greater than the change value of the second pressure sensor 109, the data processing module 111 sends a signal to the control module 112. For example: the initial value of the first pressure sensor 106 is 100 count units, and the value of the first pressure sensor 106 is 150 count units when conveying sand and gravel aggregates normally, which means that the pressure of the sand and gravel aggregates on the conveyor belt 3 on the conveyor belt 3 is 50 count units, and the allowable load-bearing value of the conveyor belt 3 is 80 count units, which means that the weight of the sand and gravel aggregates does not exceed the maximum load-bearing value of the conveyor belt 3. When the pressure detected by the first pressure sensor 106 exceeds 180 count units, for example, when the pressure detected by the first pressure sensor 106 is 200 count units, it means The sand and gravel aggregate on the conveyor belt 3 exceeds 20 counting units. When the push rod 502 pushes 30 counting units of sand and gravel aggregate into the collection box 101, the pressure of the sand and gravel aggregate on the support plate 107 is 30 counting units. At this time, the value of the first pressure sensor 106 is 170 counting units. As the conveyor belt 3 is transported, the pressure on the conveyor belt 3 decreases, which can cause the value on the first pressure sensor 106 to decrease accordingly. When the value of the first pressure sensor 106 is lower than 150 counting units and the change value of the second pressure sensor 109 is greater than 0, the data processing module 111 sends a signal to the control module 112, and the control module 112 controls the electric push rod 108 to extend and maintain it for a period of time at the longest. When the sand and gravel aggregate falls onto the conveyor belt 3, the electric push rod 108 is controlled to shrink to the shortest.

[0029] The above are only preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
