Description

Technical Field

[0001] This utility model relates to the field of concrete feeding technology, specifically a concrete feeding machine. Background Technology

[0002] When mixing concrete, the concrete raw materials need to be put into the mixer for mixing. Due to the existing feeding equipment, the concrete mixer is fed by a feeding machine. However, the height of the feeding machine cannot be adjusted, which makes the feeding device unsuitable for feeding concrete mixing equipment of different heights.

[0003] The prior art patent document with publication number CN214644818U provides a feeding device for the production of special concrete, which includes a feeding sleeve, a spiral rod rotatably connected inside the feeding sleeve, a rotating support plate fixedly installed on the inner wall of the feeding sleeve, and one end of the spiral rod rotatably connected to the rotating support plate.

[0004] However, the feeding hopper and the feeding sleeve of the device are fixed to each other. This causes the feeding hopper to tilt when the feeding sleeve is rotated. The tilted feeding hopper is obviously not convenient to pour the material into the feeding hopper, and it is easy for the material to spill out. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a concrete feeding machine that solves the problem that the feeding machine is not effective in adjusting the height of the concrete mixer, making it unsuitable for feeding concrete mixing equipment of different heights.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a concrete feeding machine for concrete production, comprising a feeding frame, wherein the feeding frame is provided with a feeding device for conveying concrete to processing equipment, and the feeding frame is provided with an adjusting component for adjusting the feeding device to adapt to the height of the processing equipment;

[0007] The feeding device includes an outer sleeve connected to the adjusting component, which is set within the enclosure of the feeding frame. A feeding pipe extends through the inside of the outer sleeve, and a flexible discharge pipe is installed at one end of the feeding pipe.

[0008] The adjusting component includes a drive sleeve installed on the feeding rack. Inside the feeding rack, at the center of the feeding pipe, there is a torsion shaft connected to the outer sleeve. The torsion shaft is symmetrically arranged with the front and rear ends of the outer sleeve and its diameter is greater than the thickness of the outer sleeve. The distance between the two torsion shafts is compensated by ring plates at the upper and lower ends of the outer sleeve.

[0009] In one embodiment, the feeding pipe is composed of a pipe body and a feeding pipe. The pipe body is a straight line extending inside the outer sleeve in the shape of a central round rod. The pipe body located at the right end of the outer sleeve is connected to the feeding pipe. The feeding pipe is opened in a semi-circular shape and its diameter is larger than that of the pipe body. Its left end is connected to the right end of the tank body with a connecting ring. A material passage cavity with the same diameter as the pipe body is connected to the bottom surface of the feeding pipe. The auger placed inside the pipe body extends into the material passage cavity.

[0010] The flexible discharge pipe is located at the left end of the pipe body and connects to the processing equipment.

[0011] In one embodiment, the feeding pipe is connected to the front and rear side walls of the material passage cavity by a transition plate. The transition plate is inclined. The right end of the feeding pipe is connected to a driver mounting sleeve for driving the auger. The driver mounting sleeve is placed on the feeding rack. The driver is placed inside the driver mounting sleeve and connected to the auger extending inside the driver mounting sleeve.

[0012] In one embodiment, the outer casing includes a sleeve body and a heating band installed on the inner wall of the sleeve body to increase the temperature inside the tube body, the heating band being attached to the outer wall of the tube body.

[0013] In one embodiment, the feeding rack includes a first support frame and a second support frame. The outer sleeve is installed on the first support frame, while the feeding pipe and the driver mounting sleeve are disposed on the second support frame. The height of the first support frame is greater than the height of the second support frame, and the bottom of the second support frame has no base plate.

[0014] In one embodiment, several weight-reducing grooves are provided on the upper and lower end faces of the sleeve, and the ring plate is connected to the upper and lower end faces of the outer sleeve by bolts.

[0015] Compared with the prior art, this utility model provides a concrete feeding machine, which has the following advantages:

[0016] In the technical solution disclosed in this utility model, the feeding device is set inside the feeding frame, and the feeding device rotates on the feeding frame through the action of the adjusting component and the support of the feeding frame. This allows the feeding device to be adjusted in height based on a rotation point. At the same time, the conveying terminal for conveying concrete to the production equipment is set as a flexible discharge pipe. This allows the flexible discharge pipe to compensate for the difference in the connection angle between the concrete output direction and the production equipment, reducing the discomfort of the conveying angle between the pipe and the production equipment, increasing the amount of concrete material retained during the conveying process and improving the connection between the conveying and the equipment.

[0017] By installing an outer jacket around the pipe, the heating effect of the jacket on the pipe body allows the pipe body to maintain a certain temperature. This design effectively mitigates the impact of cold weather on the fluidity of concrete, maintains the existing flow of concrete within the pipe body, and prevents blockage caused by the inability to flow due to temperature drop, thus effectively increasing the overall smoothness of the feeding device's operation.

[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Figures 1-4As an embodiment of this utility model, the specific problem addressed by this embodiment is: when mixing concrete, it is necessary to put the concrete raw materials into the mixing mixer for mixing. Due to the limitations of existing feeding equipment, which uses a feeding machine to feed the concrete mixer, the height of the feeding machine cannot be adjusted, making the feeding device 2 unsuitable for feeding concrete mixing equipment of different heights. Based on the above, research was conducted on the prior art. Patent document CN214644818U provides a feeding device 2 for special concrete production, offering a solution. However, in this device, the feeding hopper and the feeding sleeve are fixed together. This causes the feeding hopper to tilt when the feeding sleeve rotates. This tilted feeding hopper is obviously inconvenient for pouring material into the hopper, easily leading to material spillage. To address the problems existing in the prior art, this solution describes a concrete feeding machine. The feeding device 2 is installed inside the feeding frame 1, and through the action of the adjusting component 3 and the support of the feeding frame 1, the feeding device 2 rotates on the feeding frame 1. This allows for height adjustment of the feeding device 2 based on a single rotation point. Simultaneously, the conveying terminal for supplying concrete to the production equipment is set as a flexible discharge pipe 23. This allows for compensation when there is a difference in the connection angle between the concrete output direction and the production equipment, reducing the incompatibility of the conveying angle between the pipe body 221 and the production equipment, increasing the amount of concrete retained during conveying, and improving the continuity of the conveying process.

[0027] A concrete feeding machine includes a feeding frame 1, inside which is a feeding device 2 for conveying concrete to processing equipment. The feeding frame 1 is equipped with an adjusting component 3 for adjusting the feeding device 2 to adapt to the height of the processing equipment. The feeding device 2 includes an outer sleeve 21 connected to the adjusting component 3 and located within the enclosure of the feeding frame 1. A feeding pipe 22 extends through the inner sleeve 21. A flexible discharge pipe 23 is installed at one end of the feeding pipe 22. The flexible discharge pipe 23 is located at the left end of the feeding pipe 22 and connects to the processing equipment. It is made of rubber and can be adjusted to accommodate different angles of the receiving port of the processing equipment, compensating for the angular deviation between the pipe body 221 and the receiving port of the processing equipment after adjustment.

[0028] The adjusting component 3 includes a drive sleeve 31 installed on the feeding rack 1. Inside the feeding rack 1, at the center of the feeding pipe 22, there is a torsion shaft 32 connected to the outer sleeve 21. Inside the drive sleeve 31, there is a drive motor coaxially connected to the torsion shaft 32. The torsion shaft 32 and the front and rear ends of the outer sleeve 21 are symmetrically arranged and its diameter is greater than the thickness of the outer sleeve 21. The distance between the two torsion shafts 32 is compensated by ring plates at the upper and lower ends of the outer sleeve 21. The ring plates are connected to the upper and lower end faces of the outer sleeve 21 by bolts to increase the consistency of rotation at both ends.

[0029] The feeding pipe 22 is composed of a pipe body 221 and a feeding pipe 222. The feeding frame 1 includes a first support frame 11 and a second support frame 12. The outer sleeve 21 is installed on the first support frame 11, while the feeding pipe 22 and the driver mounting sleeve 226 are set on the second support frame 12. The height of the first support frame 11 is greater than the height of the second support frame 12. The bottom of the second support frame 12 has no bottom plate. The pipe body 221 extends in a straight line inside the outer sleeve 21 in the shape of a central round rod. The pipe body 221 located at the right end of the outer sleeve 21 is connected to the feeding pipe 222. The feeding pipe 222 is semi-circular and has a diameter larger than that of the pipe body 221. Its left end is connected to the right end of the tank with a connecting ring 223. The bottom surface of the feeding pipe 222 is connected to a material passage cavity 224 with the same diameter as the pipe body 221. The auger 24 placed inside the pipe body 221 extends into the material passage cavity 224, outputting concrete from the feeding pipe 222 to the pipe body 221 and the flexible discharge pipe 23.

[0030] The feeding pipe 222 is connected to the front and rear side walls of the material passage cavity 224 by a transition plate 225. The transition plate 225 is inclined. The right end of the feeding pipe 222 is connected to the driver mounting sleeve 226 for driving the auger 24. The driver mounting sleeve 226 is placed on the feeding rack 1. The driver is placed inside the driver mounting sleeve 226 and connected to the auger 24 extending inside the driver mounting sleeve 226. The driver is a drive motor that drives the auger 24 to rotate and transport concrete.

[0031] The outer sleeve 21 includes a sleeve body and a heating belt installed on the inner wall of the sleeve body to increase the temperature inside the tube 221. The heating belt is attached to the outer wall of the tube 221. Several weight-reducing grooves are opened on the upper and lower end faces of the sleeve body. The heating effect of the heating belt on the tube 221 ensures that the inside of the tube 221 can always maintain a certain temperature. This setting effectively alleviates the impact of cold weather on the fluidity of concrete, maintains the existing fluidity of concrete in the tube 221, avoids blockage of the tube 221 due to the inability to flow due to temperature drop, and effectively increases the overall smoothness of operation of the feeding device 2.

[0032] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
