Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building construction equipment, in particular to a buffer structure for concrete pouring. Background Art
[0002] In the process of construction, concrete pouring is required, among which vertical transportation of concrete is a common method of concrete transportation. In normal high-drop vertical transportation of concrete, chutes are often used for vertical transportation. However, this technology is prone to engineering accidents such as outlet shock and pipe breakage when concrete with a large drop enters the warehouse vertically. The impact force of concrete aggregate coming out of the pipe is relatively large, causing aggregate splashing, posing a threat to the construction workers on the warehouse surface, and posing a serious safety hazard. For this reason, we proposed a buffer structure for concrete pouring.
[0003] A Chinese patent application with publication number CN218061491U discloses a buffer device for vertical concrete delivery, including a chute, a clip is fixedly installed on the outer wall of the chute, a fixing plate is fixedly installed on the left end of the outer wall of the clip, a fixing screw is threadedly connected on the fixing plate, a flange is fixedly installed on the upper end of the outer wall of the chute, buffers are staggered and fixedly installed on the inner wall of the chute, a buffer bin is opened at the lower end of the inner wall of the chute, and a reinforcing wall is fixedly installed on the lower end of the outer wall of the buffer bin. The falling speed of concrete materials in the chute is reduced by arranging the buffer, and the buffer bin is arranged to utilize this part of concrete to buffer the subsequent falling concrete, and the flow direction of the concrete materials is changed multiple times by arranging the spiral deceleration tube to reduce the speed of the concrete materials when flowing out of the pipeline, and reduce the impact force of the concrete aggregate when coming out of the pipeline, thereby reducing the splash of aggregate and reducing the construction risks of the construction personnel on the silo surface.
[0004] However, it still has the following disadvantages in actual use:
[0005] 1. The above-mentioned buffer device for vertical concrete delivery, after the concrete falls from the chute, it will fall into the buffer bin, but the chute is too high, the concrete will directly fall to the bottom of the buffer bin, which will cause the problem of dispersion;
[0006] 2. The above-mentioned buffer device for vertical concrete delivery reduces the speed of concrete materials flowing out of the pipe by setting a spiral deceleration tube to change the flow direction of concrete materials multiple times. However, when there are more aggregates, the upper aggregates will squeeze the lower aggregates, resulting in a very fast pouring speed. At the same time, the spiral deceleration tube may also get stuck, thereby reducing the buffering effect.
[0007] To this end, we provide a buffer structure for concrete pouring to solve the above problems. Utility Model Content
[0008] The utility model aims to provide a buffer structure for concrete pouring, which facilitates the discharge of concrete for pouring through a discharge component to avoid blockage and can clean the discharge pipe at the same time. The buffer component can buffer the poured concrete and prevent the concrete from falling and causing dispersion, thereby solving the problems of the existing buffer structure for concrete pouring.
[0009] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0010] The utility model discloses a buffer structure for concrete pouring, comprising a feeding funnel, a storage box and a discharge pipe, wherein the lower side wall of the feeding funnel is detachably fixedly connected to the storage box, the right side wall of the storage box is detachably fixedly connected to the discharge pipe, the discharge port of the storage box is communicated with the feed port of the discharge pipe, a discharge assembly is installed on the inner side wall of the discharge pipe, and a buffer assembly is installed on the discharge port of the discharge pipe; a coupling is installed on the output end of a rotating motor of the discharge assembly, a rotating shaft is installed on the right side of the coupling, and a spiral sheet is installed on the outer side wall of the rotating shaft; a buffer plate is installed on the inner side wall of a buffer bin of the buffer assembly, a buffer spring is installed on the upper side wall of the buffer plate, and rotating shafts are installed on both ends of the buffer plate.

[0012] The utility model is further configured that the output end of the rotating motor is detachably fixedly connected to the rotating shaft through a coupling, and the rotating motor is connected to the controller through a wire.
[0013] The utility model is further configured that the outer side wall of the rotating shaft is detachably fixedly connected to the spiral sheet, and the outer side wall of the spiral sheet is slidably connected to the inner side wall of the discharge pipe.
[0014] The utility model is further configured such that the end of the discharge pipe is arranged in an arc shape, and the discharge pipe is arranged to be inclined downward, and the lower side wall of the discharge pipe is detachably fixedly connected to the buffer bin.
[0015] The utility model is further configured such that the discharge port of the discharge pipe is communicated with the feed port of the buffer bin, and two buffer plates are symmetrically arranged on the inner side wall of the buffer bin, and the end surfaces of the two buffer plates are fitted to each other.
[0016] The utility model is further configured such that both ends of the buffer plate are detachably fixedly connected to the rotating shaft, and the buffer plate is rotatably connected to the buffer bin via the rotating shaft.
[0017] The utility model is further configured such that the buffer plates are all arranged to be inclined downward, the surfaces of the buffer plates are detachably fixedly connected to the buffer springs, and the fixed ends of the buffer springs are detachably fixedly connected to the inner side walls of the buffer bins.
[0018] The utility model has the following beneficial effects:
[0019] 1. The utility model provides a discharge assembly. After the concrete in the storage box falls into the discharge pipe, it will be between the spiral blades. The rotating motor is started to drive the rotating shaft to rotate under the action of the coupling. The rotating shaft drives the spiral blades to rotate during continuous rotation. The spiral blades will continuously push the concrete out of the discharge pipe during rotation. At the same time, the speed of the rotating motor can be controlled to control the discharge speed of the concrete, thereby playing a certain buffering effect. At the same time, the concrete adhered to the side wall of the discharge pipe will be cleaned during the continuous forward movement of the spiral blades, and the situation that blockage affects the pouring can be avoided. The problem of reducing the speed of the concrete material flowing out of the pipeline by repeatedly changing the flow direction of the concrete material by providing a spiral reducer tube, but when there are more aggregates, the upper aggregates will squeeze the lower aggregates, resulting in a very fast pouring speed. At the same time, the spiral reducer tube may also be stuck, thereby reducing the buffering effect.
[0020] 2. The utility model sets a buffer component. After the concrete falls from the discharge pipe, it will fall on the buffer plate, pushing the buffer plate to move downward. During the downward movement of the buffer plate, the buffer spring will be pulled. Under the condition of reaction force, the buffer plate will be pulled upward to continuously buffer the concrete, so that the concrete falls from the middle of the two buffer plates to converge, which can avoid the dispersion caused by the concrete falling directly from a high place. The buffer springs set above and below the buffer plate have the same effect, so there is no excessive restriction on the position of the buffer springs, which solves the problem that after the concrete falls from the chute, it will fall into the buffer bin, but the chute is too high, and the concrete will directly fall to the bottom of the buffer bin, causing dispersion.

DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Specific embodiment 1
[0031] See also Figure 1 , Figure 2 and Figure 3 The utility model is a buffer structure for concrete pouring, including a feeding funnel 1 and a lower side wall of the feeding funnel 1 detachably fixedly connected to a storage box 101, the feeding funnel 1 is convenient for adding concrete, the storage box 101 can temporarily store the added concrete, the right side wall of the storage box 101 is detachably fixedly connected to a discharge pipe 102, the discharge pipe 102 is convenient for the discharge of concrete, and the discharge port of the storage box 101 is communicated with the feed port 102a of the discharge pipe 102, which is convenient for the flow of concrete, and the inner side wall of the discharge pipe 102 is installed with a discharge assembly 2, the discharge assembly 2 is convenient for the discharge of concrete, the discharge pipe 102 is blocked, and the discharge pipe 102 can be cleaned at the same time, which solves the problem that the existing concrete pouring speed cannot be effectively controlled and the buffering effect is poor.
[0032] Specifically, the output end of the rotating motor 201 of the discharge component 2 is detachably fixedly connected to the rotating shaft 203 through a coupling 202. The coupling 202 plays a connecting role, connecting the rotating motor 201 to the controller through a wire, so as to facilitate the control of the start of the rotating motor 201. The outer wall of the rotating shaft 203 is detachably fixedly connected to the spiral piece 204, and the spiral piece 204 can promote the discharge of concrete to avoid blockage.
[0033] Furthermore, a motor frame 201a is installed on the inner wall of the storage box 101, and the motor frame 201a facilitates the installation of the rotating motor 201. The storage box 101 is bolted to the rotating motor 201 through the motor frame 201a to fix the rotating motor 201. At the same time, the outer wall of the spiral sheet 204 is slidingly connected to the inner wall of the discharge pipe 102, which facilitates the rotation of the spiral sheet 204 and the cleaning of the discharge pipe 102. The end of the discharge pipe 102 is arranged in an arc shape, which can have a certain buffering effect, and the discharge pipe 102 is arranged to be inclined downward to facilitate the discharge of concrete.
[0034] The operation process of this embodiment is as follows: concrete is added to the feeding funnel 1, and it will enter the storage box 101 from the discharge port of the feeding funnel 1. After the concrete in the storage box 101 falls into the discharge pipe 102, it will be between the spiral blades 204.

Specific embodiment 2
[0036] See also Figure 1 , Figure 2 and Figure 4 On the basis of the specific embodiment 1, a buffer component 3 is installed at the discharge port of the discharge pipe 102. The buffer component 3 can buffer the concrete and prevent the concrete from falling and causing dispersion, thereby solving the existing problem that the concrete will cause dispersion when falling.
[0037] Specifically, both ends of the buffer plate 302 of the buffer assembly 3 are detachably fixedly connected to the rotating shaft 304, and the buffer plate 302 can play a buffering effect.

Two buffer plates 302 are symmetrically arranged on the inner wall of the buffer bin 301, and the end faces of the two buffer plates 302 are in contact with each other, which can play an effective buffering effect. At the same time, in the case of gathering the concrete, the buffer plates 302 are all arranged to be inclined downward to facilitate the discharge of the concrete.
[0039] The operation process of this embodiment is as follows: after the concrete falls from the discharge pipe 102, it will fall on the buffer plate 302, pushing the buffer plate 302 to move downward, and in the process of the buffer plate 302 moving downward, the buffer spring 303 will be pulled, and under the condition of reaction force, the buffer plate 302 will be pulled upward, which will continuously have a buffering effect on the concrete, so that the concrete falls from the middle of the two buffer plates 302 and converges, which can avoid the discrete situation caused by the concrete falling directly from a high place. The buffer spring 303 is set above and below the buffer plate 302 to have the same effect, so there is no excessive constraint on the position of the buffer spring 303.
