Description

Technical Field

[0001] The present invention belongs to the technical field of construction equipment, and in particular, relates to a quantitative feeding device for construction. Background Art

[0002] A quantitative feeding device for construction is a material handling machine that continuously conveys materials on a certain line, also known as a continuous conveyor. The conveyor can perform horizontal, inclined, and vertical conveying. However, after many feeding devices finish feeding, the materials just drop directly, but they do not have the functions of aggregating materials and adjusting the feeding speed, which affects the subsequent use convenience.

[0003] After retrieval, a Chinese patent document (authorized announcement number CN217866612U) discloses a quantitative feeding device for construction, which includes a trolley and a feeding port. The upper end of the trolley penetrates upward inside with the feeding port. Both the front and rear sides of the outer wall of the lower end of the trolley are provided with position adjustment devices. A plate chain is arranged at the lower end of the trolley. Side plates are arranged at both the front and rear ends of the plate chain. Columns are arranged on the upper side of the outer walls of both the side plates at the lower end. A residual material collection device is arranged below the plate chain. A motor box is arranged on the left side of the front end of the plate chain. By arranging position adjustment devices on both the front and rear sides of the lower end of the trolley, the trolley can move on the upper side of the plate chain and adjust its position, so that the trolley can better and more conveniently cooperate with other equipment, and at the same time, the trolley can be removed more conveniently and easily, which is convenient for maintenance and troubleshooting. By arranging a residual material collection device below the plate chain, the dropped residual materials can be more conveniently collected, cleaned, and recycled, which can not only keep the site clean, but also improve the recycling rate and reduce the construction cost. However, the materials of the above patent drop directly after feeding, but do not have the functions of aggregating materials and adjusting the feeding speed, which affects the subsequent use convenience. Summary of the Invention

[0005] To achieve the above purpose, the present invention provides the following technical solution: A quantitative feeding device for construction, comprising:

[0006] A conveyor for feeding raw materials for construction;

[0007] A storage hopper is arranged above the conveyor. The bottom end of the storage hopper is communicated with a discharge frame for quantitative discharging. The bottom end of the discharge frame is communicated with an aggregate hopper. An adjusting assembly for adjusting the discharge amount is installed on the side of the discharge frame;

[0008] A plurality of connecting blocks are evenly connected to the outer periphery of the conveyor. The top end of the connecting block is connected to a storage box with an opening on one side. The side of the storage box is communicated with a discharge hopper. The top end of the storage box is provided with a feeding channel, and the size of the feeding channel is smaller than the inner diameter size of the aggregate hopper;

[0009] A discharge pipe is connected to the side of the discharge hopper. A plurality of threaded channels are formed on the outer periphery of the discharge pipe. An adjusting threaded rod for adjusting the discharge speed of the discharge pipe is threadedly connected to the threaded channels. The side of the discharge pipe away from the discharge hopper is configured as an inclined surface. An inclined connecting block is connected to the side of the discharge pipe. An adjusting electric push rod is connected to the side of the inclined connecting block. A blocking plate for blocking the discharge pipe is connected to the moving part of the adjusting electric push rod. A C-shaped sliding plate is connected to the outer periphery of the discharge pipe. The sliding plate is slidably connected to the blocking plate.

[0010] As a preferred embodiment, the adjusting assembly includes:

[0011] A mounting plate, shaped like a C, is fixedly connected to the side of the discharge frame;

[0012] A plurality of inclined electric push rods are fixedly connected to the vertical inner wall of the mounting plate. The moving parts of the plurality of inclined electric push rods are connected to an inclined blocking block.

[0013] As a preferred embodiment, a plurality of through channels for the blocking block to pass through are arranged side by side on the side of the discharge frame.

[0014] As a preferred embodiment, a counterweight plate is arranged below the conveyor. Two side connecting plates are fixedly connected to the outer periphery of the storage hopper. The bottom end of the side connecting plate is fixedly connected to the top end of the counterweight plate. A plurality of brake casters for improving stability are fixedly connected to the bottom end of the counterweight plate. A plurality of limiting frames for limiting the counterweight are fixedly connected to the top end of the counterweight plate.

[0015] As a preferred embodiment, two stabilizing plates are fixedly connected to the outer periphery of the conveyor. A sliding groove is formed on the side of the counterweight plate. A plurality of sliding plates are arranged in the sliding groove. L-shaped limiting plates are connected to both sides of the sliding plate. The length of the sliding plate is greater than the width of the counterweight plate.

[0016] As a preferred embodiment, threaded channels arranged at equal intervals are formed on the side of the stabilizing plate. Two of the threaded channels are threadedly connected to a T-shaped fixing threaded rod.

[0017] As a preferred embodiment, a bearing is sleeved on the outer periphery of the fixing threaded rod. The movable outer ring of the bearing is fixedly connected to a movable pipe. An upper threaded rod is fixedly connected to the outer periphery of the movable pipe. A lower threaded rod is arranged below the upper threaded rod. A clamping plate adapted to the limiting plate is fixedly connected to the bottom end of the lower threaded rod.

[0018] As a preferred embodiment, a threaded channel is formed at the top end of the limiting plate. A tightening threaded rod for fixing the clamping plate is threadedly connected to the threaded channel. The upper threaded rod and the lower threaded rod are commonly threadedly connected to a threaded pipe. An outer ring plate is connected to the outer periphery of the threaded pipe.

[0019] As a preferred embodiment, the thread spiral directions of the upper threaded rod and the lower threaded rod are opposite.

[0020] As a preferred embodiment, the outer periphery of the conveyor is also connected with a plurality of support blocks for supporting the storage box and the storage hopper.

[0021] Compared with the prior art, the technical effects and advantages of the present invention are as follows:

[0022] The quantitative feeding device for construction can realize material storage by cooperating with the storage box and the discharge hopper. When the storage box and the discharge hopper rotate to a vertical state or a nearly vertical state with the conveyor, the material falls into the lower part of the discharge hopper and the storage box with gravity, and is discharged by the discharge hopper and the discharge pipe in a centralized manner. The discharge accuracy is higher. The adjusting threaded rod is rotated in advance so that the end of the adjusting threaded rod is inserted into the discharge pipe to achieve blocking and reduce the discharge speed. The electric push rod is adjusted to different degrees of contraction to release the different degrees of blocking of the blocking plate, and the discharge speed can also be adjusted to meet different usage needs.

[0023] The quantitative feeding device for construction construction has an adjustment component that can adjust the storage amount of the material discharging frame, control the three inclined electric push rods on the top to retract, so that the raw materials fall and fall on the lowest blocking block. According to the needs of quantitative discharging, select the inclined electric push rod at a suitable position to extend, so that the attached blocking block abuts against the discharging frame to complete the blocking, control the lowest inclined electric push rod to retract, the blocking block moves, and the blocking is released. The raw materials between the two blocking blocks will be discharged with gravity to achieve quantitative processing. If the discharging amount needs to be finely adjusted, when the raw materials just exceed the second to last blocking block, control the designated inclined electric push rod on the top to extend. At this time, the second to last inclined electric push rod is extended by a designated length, so that the attached blocking block occupies the designated space of the discharging frame, thereby performing fine adjustment, and then control the upper inclined electric push rod to retract to achieve complete discharging, and then control the inclined electric push rod to extend and block, and repeat the previous discharging operation.

[0024] The quantitative feeding device for construction can ensure the overall stability of the counterweight plate. If the stability is insufficient, a counterweight can be placed in the limit frame of the counterweight plate to improve the overall stability. By changing the rotation degree of the threaded tube and the position of the fixed threaded rod, the angle of the conveyor relative to the counterweight plate can be changed. If a large adjustment is required, the lower threaded rod at the lower position can be removed to increase the degree of change, change the position of the slide plate and the limit plate, and use the tightening threaded rod to tighten and fix them to meet the needs of stable adjustment.

[0025] The quantitative feeding device for construction can not only gather and concentrate materials, but also adjust the feeding speed to meet different usage needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] In the following description, numerous specific details are given to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without one or more of these details. In other instances, some well-known technical features are not described to avoid obscuring the present invention.

[0041] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., depending on actual needs.

[0042] Please refer to Figures 1 to 10 , a quantitative feeding device for building construction. This embodiment includes:

[0043] A conveyor 1 for feeding raw materials for building construction;

[0044] A storage hopper 2 is arranged above the conveyor 1. The bottom end of the storage hopper 2 is communicated with a discharge frame 3 for quantitative discharging. The bottom end of the discharge frame 3 is communicated with an aggregate hopper 4. A regulating assembly 5 for adjusting the discharge amount is installed on the side of the discharge frame 3;

[0045] A plurality of connecting blocks 6 are evenly connected to the outer periphery of the conveyor 1. The top end of the connecting block 6 is connected to a storage box 7 with an opening on one side. A number of support blocks 29 for supporting the storage box 7 and the storage hopper 2 are also connected to the outer periphery of the conveyor 1. A discharge hopper 8 is communicated with the side of the storage box 7. An inlet channel is opened at the top end of the storage box 7, and the size of the inlet channel is smaller than the inner diameter size of the aggregate hopper 4;

[0046] A discharge pipe 9 is communicated with the side of the discharge hopper 8. A plurality of threaded channels are opened on the outer periphery of the discharge pipe 9. A regulating threaded rod 10 for adjusting the discharge speed of the discharge pipe 9 is threadedly connected to the threaded channels. The side of the discharge pipe 9 away from the discharge hopper 8 is configured as an inclined surface. An inclined connecting block 11 is connected to the side of the discharge pipe 9. An adjusting electric push rod 12 is connected to the side of the inclined connecting block 11. The moving part of the adjusting electric push rod 12 is connected to a blocking plate 13 for blocking the discharge pipe 9. A C-shaped sliding plate 14 is connected to the outer periphery of the discharge pipe 9. The sliding plate 14 is slidably connected to the blocking plate 13. The raw material falls from the aggregate hopper 4 into the storage box 7. After the feeding is completed, the conveyor 1 moves for conveying. When the storage box 7 and the discharge hopper 8 rotate with the conveyor 1 to the vertical state or close to the vertical state, the material falls into the lower half of the discharge hopper 8 and the storage box 7 due to gravity and is discharged concentratedly from the discharge hopper 8 and the discharge pipe 9. First, rotate the regulating threaded rod 10 so that the end of the regulating threaded rod 10 is inserted into the discharge pipe 9 to achieve blocking and reduce the feeding speed. The adjusting electric push rod 12 contracts to different degrees, releasing the blocking of the blocking plate 13 to different degrees, which can also adjust the feeding speed. The raw material is discharged from the discharge port of the discharge pipe 9.

[0047] The regulating assembly 5 includes:

[0048] The mounting plate 51 is C-shaped and fixedly connected to the side of the discharge frame 3;

[0049] A plurality of inclined electric push rods 52 are fixedly connected to the vertical inner wall of the mounting plate 51, and the moving parts of the plurality of inclined electric push rods 52 are connected with inclined blocking blocks 53. A plurality of parallel passages for the blocking blocks 53 to pass through are provided on the side of the discharge frame 3, and the raw materials used for construction are introduced into the storage hopper 2 by means of external equipment. If the discharge amount needs to be finely adjusted, when the raw materials just exceed the second-to-last blocking block 53, the upper designated inclined electric push rod 52 is controlled to extend. At this time, the second-to-last inclined electric push rod 52 is extended by a specified length, so that the attached blocking block 53 occupies the specified space of the discharge frame, thereby performing fine adjustment, and then the upper inclined electric push rod 52 is controlled to retract to achieve complete discharge, and then the inclined electric push rod 52 is controlled to extend and block, and the lowest inclined electric push rod 52 is controlled to retract to release the blockage of the attached blocking block 53, thereby achieving quantitative discharge.

[0050] In order to meet the needs of use, a counterweight plate 15 is provided at the bottom of the conveyor 1, and two side connecting plates 16 are fixedly connected to the outer periphery of the storage hopper 2. The bottom ends of the side connecting plates 16 are fixedly connected to the top of the counterweight plate 15, and the bottom end of the counterweight plate 15 is fixedly connected with a plurality of brake casters 17 for improving stability, and the top end of the counterweight plate 15 is fixedly connected with a plurality of limit frames 18 for limiting the counterweight object. The counterweight plate 15 and the brake casters 17 are pushed to the specified positions, and the brakes of the brake casters 17 are turned on. If the stability is insufficient, the counterweight object can be placed in the limit frame 18 of the counterweight plate 15 to improve the overall stability.

[0051] To adjust the tilt angle, two stabilizing plates 19 are fixedly connected to the outer periphery of the conveyor 1. A chute is provided on the side surface of the counterweight plate 15. A plurality of sliding plates 20 are arranged in the chute. L-shaped limiting plates 21 are connected to both sides of the sliding plate 20. The length of the sliding plate 20 is slightly greater than the width of the counterweight plate 15. On the premise of satisfying the tightening of the two tightening threaded rods 27, a slight position adjustment can be made. Equally spaced threaded channels are provided on the side surface of the stabilizing plate 19. Two of the threaded channels are threadedly connected with T-shaped fixing threaded rods 22. A bearing is sleeved on the outer periphery of the fixing threaded rod 22. The movable outer ring of the bearing is fixedly connected with a movable pipe 23. An upper threaded rod 24 is fixedly connected to the outer periphery of the movable pipe 23. A lower threaded rod 25 is arranged below the upper threaded rod 24. The bottom end of the lower threaded rod 25 is fixedly connected with a clamping plate 26 adapted to the limiting plate 21. A threaded channel is provided at the top end of the limiting plate 21. A tightening threaded rod 27 for fixing the clamping plate 26 is threadedly connected to the threaded channel. The outer peripheries of the upper threaded rod 24 and the lower threaded rod 25 are commonly threadedly connected with a threaded pipe 28. If the existing adjustment still meets different tilt requirements, a longer threaded pipe 28 can be replaced. Not in the illustrated position, an outer ring plate 30 is connected to the outer periphery of the threaded pipe 28. The thread spiral directions of the upper threaded rod 24 and the lower threaded rod 25 are opposite. By changing the rotation degree of the threaded pipe 28 and the position of the fixing threaded rod 22, the angle of the conveyor 1 relative to the counterweight plate 15 can be changed. When a large adjustment is required, the lower threaded rod 25 at the lower position can be removed to increase the change degree. After the fixing threaded rod 22 passes through the threaded channel, the positions of the sliding plate 20 and the limiting plate 21 are changed, and the tightening threaded rod 27 is used for tightening and fixing.

[0052] The conveyor 1, the adjusting electric push rod 12, and the tilting electric push rod 52 are all set as existing technologies. Their working principles, dimensions, and models are irrelevant to the functions of this application, so no more description will be given. The control mode of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present invention is mainly used to protect mechanical devices, so the control mode and circuit connection of the present invention will not be explained in detail.

[0053] Working principle

[0054] For this quantitative feeding device for building construction, the counterweight plate 15 and the brake caster 17 are pushed to the designated position, and the braking of the brake caster 17 is turned on. If the stability is insufficient, weights can be placed in the limiting frame 18 of the counterweight plate 15 to improve the overall stability. By changing the rotation degree of the threaded pipe 28 and the position of the fixing threaded rod 22, the angle of the conveyor 1 relative to the counterweight plate 15 can be changed. When a large adjustment is required, the lower threaded rod 25 at the lower position can be removed to increase the change degree. After the fixing threaded rod 22 passes through the threaded channel, the positions of the sliding plate 20 and the limiting plate 21 are changed, and the tightening threaded rod 27 is used for tightening and fixing;

[0055] Use an external device to introduce the raw materials used in building construction into the storage hopper 2. When the discharge volume needs to be finely adjusted, when the raw materials just exceed the penultimate blocking block 53, control the specified tilting electric push rod 52 above to extend. At this time, the penultimate tilting electric push rod 52 extends by a specified length, so that the attached blocking block 53 occupies a specified space in the discharge frame, so as to carry out fine adjustment. Then control the tilting electric push rod 52 above to contract to achieve complete blanking. Then control this tilting electric push rod 52 to extend and block, control the lowermost tilting electric push rod 52 to contract, and release the blocking of the attached blocking block 53 to achieve quantitative blanking;

[0056] The raw materials fall from the aggregate hopper 4 into the storage box 7. After the blanking is completed, the conveyor 1 moves for conveying. When the storage box 7 and the discharge hopper 8 rotate to the vertical state or close to the vertical state with the conveyor 1, the materials fall into the lower half of the discharge hopper 8 and the storage box 7 by gravity, and are discharged centrally from the discharge hopper 8 and the discharge pipe 9. First, rotate the adjusting screw rod 10 so that the end of the adjusting screw rod 10 is inserted into the discharge pipe 9 to achieve blocking and reduce the blanking speed. The adjusting electric push rod 12 contracts to different degrees, and releases the blocking of the blocking plate 13 to different degrees, which can also adjust the blanking speed. The raw materials are discharged from the discharge port of the discharge pipe 9.

[0058] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
