A bucket-lift concrete mixing station lifting bucket

Abstract

A bucket-lift concrete mixing station lifting hopper, when the lifting hopper is at the lowest position of the lifting hopper guide rail, the aggregate batching machine adds the ingredients into the lifting hopper, and then the power mechanism drives the lifting hopper to move upward along the lifting hopper guide rail through the guide wheel. The lifting hopper does not need to stop and wait, and directly rotates through the change mechanism until the lifting hopper outlet faces downward and is located above the aggregate inlet. At this time, the lifting hopper is at the feeding angle. When the main mixer is ready for feeding, the bucket door hook rotation drive mechanism drives the bucket door hook to rotate outward, so that its hook groove is away from the bucket door. Under the action of gravity, the bucket door flips outward through the rotating shaft I, so that the aggregate in the lifting hopper flows out from the lifting hopper outlet and falls into the main mixer through the aggregate inlet. The high-position waiting process is cancelled during the lifting hopper's upward movement, and it moves directly to the top, saving the time for the lifting hopper to start running again, and reducing the impact of the lifting hopper's secondary start and stop on the equipment.

Description

Technical Field

[0001] The invention relates to the technical field of concrete mixing stations, and in particular to a bucket-lift concrete mixing station material lifting bucket. Background Art

[0002] With the continuous progress of scientific and technological modernization, concrete production equipment has been widely used in the construction field. At present, there are several different ways to transport aggregates in concrete mixing plant equipment. The main method is now the conveyor belt method. This method has high aggregate transportation efficiency. Aggregates can be transported to the storage bin on the top of the equipment in advance, so that the concrete production efficiency can be maximized. However, there are also obvious disadvantages such as high equipment manufacturing cost and large floor space. Another is the bucket-lift concrete mixing plant that uses a winch to drive the lifting hopper to transport aggregates. Its advantages are relatively low manufacturing cost and small floor space. However, due to the slow running speed of the lifting hopper and the fact that the lifting hopper cannot run directly to the top, it needs to stop at a higher position and wait for the main mixer to be emptied before starting up again, resulting in production efficiency not as good as the belt transport mixing plant. In addition, the stopping and restarting of the lifting hopper waiting at a high position causes the main machine to shake more, the wire rope is impacted and worn, the life is short, and the wire rope breaks and falls on the lifting hopper. Summary of the invention

[0003] In order to overcome the deficiencies of the above technologies, the present invention provides a bucket-lift concrete mixing station lifting hopper which can cancel the high-position waiting during the upward movement of the hopper and directly run to the top, and directly feed the material to the main machine when receiving the feeding signal, thereby reducing the impact of the secondary start and stop of the lifting hopper on the equipment and saving the time of restarting the operation.

[0004] The technical solution adopted by the present invention to overcome the technical problems is:

[0005] A bucket-lift concrete mixing station material lifting hopper comprises a frame and a material lifting hopper frame, wherein the left and right ends of the frame are respectively provided with material lifting hopper guide rails inclined from bottom to top, the material lifting hopper is rotatably installed in the material lifting hopper frame, the left and right ends of the material lifting hopper frame are respectively provided with guide wheels rotatably installed, the guide wheels are rollingly installed on the corresponding material lifting hopper guide rails on the same side, the material lifting hopper is driven by a power mechanism to move up and down along the material lifting hopper guide rails, and a material lifting hopper outlet is provided at the upper end of the material lifting hopper, and further comprises:

[0006] The hopper door is rotatably mounted on the lifting hopper via a rotating shaft I;

[0007] N hopper door hooks are rotatably mounted on the lifting hopper via a rotating shaft II, N being a positive integer greater than or equal to 1, and a torsion spring is mounted on the rotating shaft II, one end of the torsion spring is connected to the lifting hopper, and the other end is connected to the hopper door hook, and when the hopper door blocks the outlet of the lifting hopper, the hook groove of the hopper door hook is hooked on the outer end of the hopper door under the elastic force of the torsion spring;

[0008] The direction-changing mechanism is arranged on the lifting hopper frame. When the power mechanism drives the lifting hopper to move upward to the direction-changing mechanism via the lifting hopper guide rail, the direction-changing mechanism drives the lifting hopper outlet to rotate downward to be directly above the aggregate inlet of the main mixer; and the hopper door hook rotation driving mechanism is used to drive the hopper door hook to rotate outward until the hook groove is away from the hopper door.

[0009] Furthermore, the power mechanism includes a pulley rotatably mounted on the upper end of the lifting bucket frame, one end of the wire rope is fixed to the frame after passing around the pulley, and the other end is connected to the driving motor.

[0010] Furthermore, the above-mentioned changing mechanism includes an arc-shaped arc guide rail arranged on the frame and located at the upper end of the hopper guide rail and a roller installed on the hopper. When the hopper moves upward and the roller enters the arc guide rail, the hopper rotates clockwise. When the roller moves to the feeding angle of the arc guide rail, the hopper outlet of the hopper rotates downward to be directly above the aggregate inlet of the main mixer.

[0011] Furthermore, the above-mentioned hopper hook rotation drive mechanism includes a sliding rod installed on the lifting hopper for horizontal sliding along the left and right directions, and N top blocks are arranged on the sliding rod. The head end of the top block is provided with a guide slope III. The sliding rod driving mechanism is used to drive the sliding rod to slide left and right in the horizontal direction. When the sliding rod slides to the guide slope III and contacts the corresponding hopper hook, it pushes the hopper hook to rotate outward. When the sliding rod slides to the outer end face of the top block and contacts the hopper hook, the hopper hook rotates outward until the hook groove is separated from the hopper.

[0012] In order to realize automatic door closing, it also includes a pressure plate arranged on the lifting bucket frame, and a guide slope II is arranged at the front end below the pressure plate, and a guide slope I is arranged at the inner end of the hook head of the bucket door hook, and a pressure rod is arranged on the bucket door along its length direction. When the power mechanism drives the lifting bucket to return through the changing mechanism, the pressure rod and the guide slope II slide and frictionally drive the bucket door to rotate downward until its head end is in friction contact with the guide slope I until the outer end of the bucket door is stuck in the hook groove.

[0013] Furthermore, the above-mentioned slide rod driving mechanism includes a cylinder horizontally installed on the aggregate inlet, a cylinder push plate is installed on the head end of the piston rod of the cylinder, the axis of the cylinder is coaxial with the slide rod, one end of the return spring is connected to the slide rod, and the other end is connected to the lifting hopper. When the piston rod of the cylinder is fully extended, the cylinder push plate drives the slide rod to slide until the top block contacts the hopper door hook and stretches the return spring.

[0014] The beneficial effect of the present invention is that when the lifting hopper is located at the lowest position of the lifting hopper guide rail, the aggregate batching machine adds the ingredients into the lifting hopper, and then the power mechanism drives the lifting hopper to move upward along the lifting hopper guide rail through the guide wheel. The lifting hopper does not need to stop and wait, and is directly rotated through the changing mechanism until the lifting hopper outlet is downward and located above the aggregate inlet. At this time, the lifting hopper is at the feeding angle. When the main mixer is ready for feeding, the bucket door hook rotation driving mechanism drives the bucket door hook to rotate outward, so that its hook groove is away from the bucket door. Under the action of gravity, the bucket door is flipped outward through the rotating shaft I, so that the aggregate in the lifting hopper flows out from the lifting hopper outlet and falls into the main mixer through the aggregate inlet. The high-position waiting process is cancelled during the lifting hopper's upward movement. It moves directly to the top and directly feeds the main mixer when receiving the feeding signal, saving the time for the lifting hopper to start running again and reducing the impact of the lifting hopper's secondary start and stop on the equipment.

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1 To Attachment Figure 7The present invention is further described.

[0024] A bucket-lift concrete mixing station material lifting hopper, comprising a frame and a material lifting hopper frame 10, wherein the left and right ends of the frame are respectively provided with material lifting hopper guide rails 16 which are inclined from bottom to top, a material lifting hopper 8 is rotatably installed in the material lifting hopper frame 10, and the left and right ends of the material lifting hopper frame 10 are respectively provided with guide wheels which are rotatably installed, and the guide wheels are rollingly installed on the corresponding material lifting hopper guide rails 16 on the same side, and the material lifting hopper 8 is driven by a power mechanism to move up and down along the material lifting hopper guide rails 16, and a material lifting hopper outlet 19 is provided at the upper end of the material lifting hopper 8, and further comprising: a hopper door 1 which is rotatably installed on the material lifting hopper 8 through a rotating shaft I 20; N hopper door hooks 2 which are rotatably installed on the material lifting hopper 8 through a rotating shaft II 24, and N is greater than or equal to 1. A positive integer, a torsion spring 13 is mounted on the rotating shaft II 24, one end of the torsion spring 13 is connected to the lifting hopper 8, and the other end thereof is connected to the hopper door hook 2. When the hopper door 1 blocks the lifting hopper outlet 19, the hook groove 21 of the hopper door hook 2 is hooked on the outer end of the hopper door 1 under the elastic force of the torsion spring 13; a direction-changing mechanism is arranged on the lifting hopper frame 10, when the power mechanism drives the lifting hopper 8 to move upward to the changing mechanism through the lifting hopper guide rail 16, the changing mechanism drives the lifting hopper outlet 19 of the lifting hopper 8 to rotate downward to just above the aggregate inlet 17 of the main mixer 9; and a hopper door hook rotation driving mechanism, which is used to drive the hopper door hook 2 to rotate outward until the hook groove 21 is away from the hopper door 1. When the lifting hopper 8 is located at the lowest position of the lifting hopper guide rail 16, the aggregate batching machine adds the ingredients into the lifting hopper 8, and then the power mechanism drives the lifting hopper 8 to move upward along the lifting hopper guide rail 16 through the guide wheel. The lifting hopper 8 does not need to stop and wait, and directly rotates through the changing mechanism until the lifting hopper outlet 19 faces downward and is located above the aggregate inlet 17. At this time, the lifting hopper 8 is at the feeding angle. When the main mixer 9 has the feeding conditions, the bucket door hook rotation drive mechanism drives the bucket door hook 2 to rotate outward, so that its hook groove 21 is away from the bucket door 1. Under the action of gravity, the bucket door 1 is turned outward through the rotating shaft Ⅰ20, so that the aggregate in the lifting hopper 8 flows out from the lifting hopper outlet 19 and falls into the main mixer 9 through the aggregate inlet 17. The high-position waiting process is cancelled during the upward movement of the lifting hopper 8. It moves directly to the top and directly feeds the main mixer 9 when receiving the feeding signal, saving the time of starting the lifting hopper 8 again and reducing the impact of the second start and stop of the lifting hopper 8 on the equipment.

[0025] Furthermore, the power mechanism includes a pulley 14 rotatably mounted on the upper end of the material lifting bucket frame 10, a steel wire rope 15 is wrapped around the pulley 14 and then fixed to the frame at one end, and the other end is connected to the driving motor. The driving motor drives the steel wire rope 15 to pull the pulley 14 to rotate and drives the material lifting bucket frame 10 to roll along the material lifting bucket guide rail 16 through the guide wheel to achieve up and down movement.

[0026] The direction-changing mechanism may be a structure as follows, which includes an arc-shaped arc guide rail 26 disposed on the frame and located at the upper end of the hopper guide rail 16 and a roller 18 mounted on the hopper 8. When the hopper 8 moves upward and the roller 18 enters the arc guide rail 26, the hopper 8 rotates clockwise. When the roller 18 moves to the feeding angle of the arc guide rail 26, the hopper outlet 19 of the hopper 8 rotates downward to be located directly above the aggregate inlet 17 of the main mixer 9. When the hopper 8 moves to the arc guide rail 26 through the roller 18, the hopper 8 moves along the arc direction of the arc guide rail 26, so that the hopper 8 rotates until the hopper outlet 19 faces downward and is located directly above the aggregate inlet 17.

[0027] The hopper hook rotation driving mechanism may be the following structure, which includes a slide bar 3 installed on the lifting hopper 8 in a horizontal sliding manner along the left and right directions, N top blocks 12 are arranged on the slide bar 3, and a guide slope III 25 is arranged at the head end of the top block 12. The slide bar driving mechanism is used to drive the slide bar 3 to slide left and right in the horizontal direction. When the slide bar 3 slides to the guide slope III 25 and contacts the corresponding hopper hook 2, it pushes the hopper hook 2 to rotate outward. When the slide bar 3 slides to the outer end face of the top block 12 and contacts the hopper hook 2, the hopper hook 2 rotates outward until the hook groove 21 is separated from the hopper 1. When the slide bar driving mechanism drives the slide bar 3 to drive the top block 12 to move in the direction of the hopper hook 2, each top block 12 first contacts the corresponding hopper hook 2 step by step through the guide slope III 25, and then drives the hopper hook 2 to rotate outward and compresses the torsion spring 13 to realize energy storage. At this time, the hopper door hook 2 leaves the hopper door 1, so the hopper door 1 can be flipped open, and when the slide rod driving mechanism drives the slide rod 3 to drive the top block 12 to move in the direction away from the hopper door hook 2, the top block 12 leaves the hopper door hook 2. At this time, under the elastic force of the torsion spring 13, the hopper door hook 2 is driven to rotate inward until it is hooked and fixed to the edge of the hopper door 1 through the hook groove 21, thereby locking and fixing the hopper door 1.

[0028] Furthermore, it also includes a pressure plate 6 arranged on the lifting bucket frame 10, and a guide slope II 23 is arranged at the front end below the pressure plate 6, and a guide slope I 22 is arranged at the inner end of the hook head of the bucket hook 2, and a pressure rod 7 is arranged on the bucket 1 along its length direction. When the power mechanism drives the lifting bucket 8 to return through the changing mechanism, the pressure rod 7 and the guide slope II 23 slide and frictionally drive the bucket 1 to rotate downward until its head end is in friction contact with the guide slope I 22 until the outer end of the bucket 1 is stuck in the hook groove 21. After the aggregate in the lifting hopper 8 is added to the main mixer 9, the power mechanism drives the lifting hopper 8 to return. Since the hopper door 1 remains open at this time, the lifting hopper 8 rotates in the opposite direction when the direction-changing mechanism returns. At this time, the lower end of the pressing plate on the lifting hopper frame 10 slides and rubs with the pressing rod 7 through the guiding inclined surface II 23, and then presses the hopper door 1 downward. The outer end of the hopper door 1 slides and rubs with the guiding inclined surface I 22 on the hopper door hook 2, causing the hopper door hook 2 to rotate outward. Finally, the hopper door 1 is pressed down to close the lifting hopper outlet 19. Under the elastic force of the torsion spring 13, the hook groove 21 of the hopper door hook 2 hooks on the edge of the hopper door 1, thereby locking the hopper door 1. By setting the pressing plate 6, the hopper door 1 of the lifting hopper 8 is automatically closed during the return process, which improves the automation of the equipment operation, so that when the lifting hopper 8 returns to the lower end of the lifting hopper guide rail 16 to receive materials, its lifting hopper outlet 19 is in a closed state.

[0029] The slide rod driving mechanism can be the following structure, which includes a cylinder 4 installed horizontally on the aggregate inlet 17, a cylinder push plate 5 is installed at the piston rod head end of the cylinder 4, the axis of the cylinder 4 is coaxial with the slide rod 3, one end of the return spring 11 is connected to the slide rod 3, and the other end is connected to the lifting hopper 8. When the piston rod of the cylinder 4 is fully extended, the cylinder push plate 5 drives the slide rod 3 to slide until the top block 12 contacts the bucket door hook 2, and stretches the return spring 11. The piston rod of the cylinder 4 extends outward, which drives the cylinder push plate 5 to extend outward, and the cylinder push plate 5 pushes the slide rod 3 to slide, so that the top block 12 on the slide rod 3 drives the bucket door hook 2 to rotate outward, and at this time the return spring 11 stretches and stores energy. When resetting, the piston rod of the cylinder 4 retracts inward, and the return spring 11 releases the elastic force, thereby pulling the slide rod 3 to slide in the opposite direction to achieve resetting.
