Description

Technical Field

[0001] The utility model relates to the technical field of screw conveyors, in particular to a screw conveyor used for concrete production. Background Art

[0002] A screw conveyor is a machine that uses a motor to drive the screw to rotate and push materials to achieve the purpose of conveying. It can convey horizontally, inclined or vertically. It has the advantages of simple structure, small cross-sectional area, good sealing, easy operation, easy maintenance, and convenient closed transportation.

[0003] Concrete screw conveyors are mainly used for conveying or feeding cement and cement-like materials in concrete mixing plants and other building materials processing plants. They are mainly composed of inlet and outlet pipes, conveying pipes, spiral blades and drive components. During the inclined or vertical conveying process of concrete screw conveyors, they are usually used in conjunction with special brackets, which means that when its position needs to be moved, its bracket also needs to be moved synchronously, which inevitably involves the process of disassembly, assembly and debugging, making the movement or temporary use of the screw conveyor more troublesome.

[0004] After searching, the Chinese utility model patent with publication number CN221168720U discloses a concrete conveying device for construction, including a bottom plate, two fixing blocks are symmetrically fixed on the upper side of the bottom plate, and two mounting plates are symmetrically fixed on the upper side of the bottom plate at one position of the two fixing blocks. The application facilitates the mobile use of the screw conveyor by setting it on a base with universal wheels, but after the device uses a motor to adjust the angle of the conveying pipe, since the raised end is not supported, there is a high possibility that the conveying pipe will be unstable or even shake when conveying materials. In this case, the screw conveyor will have poor conveying due to uneven load. Utility Model Content

[0005] In view of the above-mentioned prior art, the utility model provides a screw conveyor for concrete production, and the main technical problem to be solved is how to ensure smooth operation of the screw conveyor while facilitating movement.

[0006] To achieve the above purpose, the technical solution of the embodiment of the utility model is implemented as follows:

[0007] A screw conveyor for concrete production comprises a frame and a screw conveyor. The screw conveyor is installed in the frame. An adjusting mechanism is provided on the frame. The adjusting mechanism is used to adjust the angle of the screw conveyor. Connecting strips are provided at both ends of the inner side of the frame.

The top ends of the two hanging ropes are fixedly connected to the two winding drums respectively, and the bottom ends of the two hanging ropes are fixedly connected to the same clamp, which is arranged on the outside of the screw conveyor.

[0011] Furthermore, the frame is composed of two vertical rods and a horizontal rod at the top between the two, the sliding sleeve is arranged on the outside of the vertical rod, a threaded through hole is opened on one side of the sliding sleeve, and the sliding sleeve is threadedly connected with a bolt at the threaded through hole, and the connecting strip is composed of a spring steel wire bundle inside and a rubber sleeve wrapped outside.

[0012] Furthermore, the screw conveyor includes an outer shell, a spiral blade and a drive assembly. The bottom end of the outer shell is fixedly connected to a cover shell, an inner wall of one side of the cover shell is rotatably connected to a rotating rod, and a circular through hole is opened on the other side of the cover shell, and the rotating rod extends to the outside of the cover shell at the circular through hole.

[0026] Example 1

[0027] Refer to the attached Figure 1-3 The present application provides a screw conveyor for concrete production, including a frame 1 and a screw conveyor 8. The screw conveyor 8 is installed in the frame 1. The frame 1 is provided with an adjustment mechanism, which is used to adjust the angle of the screw conveyor 8. The adjustment mechanism mainly controls the lifting and lowering of the ends of the screw conveyor 8. By controlling the lifting or lowering of the two ends of the screw conveyor 8 respectively, the angle of the screw conveyor 8 can be adjusted. By controlling the lifting and lowering of the two ends respectively, a larger angle adjustment range can be achieved, so as to meet different adjustment and use requirements of the screw conveyor 8. Connecting strips 14 are provided at both ends of the inner side of the frame 1. The frame 1 is connected by the connecting strips 14. By clamping the screw conveyor 8, after the screw conveyor 8 is clamped by the connecting strip 14, a buffering effect can be achieved for it, thereby ensuring the stability of the screw conveyor 8 during operation. Both ends of the connecting strip 14 are fixedly connected with a sliding sleeve 12, which is sleeved on the outside of the frame 1, and the sliding sleeve 12 is used to adjust the position and bending degree of the connecting strip 14. By adjusting the positions of the two sliding sleeves 12 at the same time, the height of the sliding sleeve 12 can be adapted to the position change of the end of the screw conveyor 8, thereby providing sufficient support for it. By adjusting only one sliding sleeve 12, the deformation degree of the connecting strip 14 can be adjusted, thereby ensuring the clamping effect of the screw conveyor 8.

[0028] Preferably, there are two frames 1, which are located at the two ends of the outside of the screw conveyor 8, and the four corners of the outside between the two frames 1 are fixedly connected with support rods 9, and the two ends between the two support rods 9 at the top are fixedly connected with support plates 2. The frame 1 is an inverted U-shape, and the two ends of the bottom of the frame 1 are fixedly connected with universal wheels 11. By setting the structure for installing the screw conveyor 8 into a frame shape, the weight of the entire device can be reduced as much as possible, making it more convenient to push the frame 1 to use the universal wheel 11 to move the screw conveyor 8. The universal wheel 11 is provided with a brake, which can be used to ensure the stability of the screw conveyor 8 after movement.

[0029] Preferably, the adjustment mechanism includes a motor 3, which is fixedly connected to one side of the top of the support plate 2, and one end of the output shaft of the motor 3 is fixedly connected to a worm 301, and both ends of the other side of the top of the support plate 2 are fixedly connected to side panels 7, and the top between the two side panel 7 brackets is rotatably connected to a rotating shaft 5, and the middle part of the outer side of the rod body of the rotating shaft 5 is connected to a worm wheel 4 through a key, and the worm wheel 4 is meshed with the worm 301. The worm 301 drives the worm wheel 4 with a reverse self-locking effect, which can make it have stronger stability when driving the winding drum 6 to reel in the suspension rope 13, thereby avoiding the gravity of the screw conveyor 8 causing the winding drum 6 to loosen, thereby causing instability after its angle is adjusted.

[0030] Preferably, both ends of the outer side of the rod body of the rotating shaft 5 are connected to the winding drum 6 through a key, the plate body of the support plate 2 is provided with wiring holes below the two winding drums 6, and the support plate 2 is provided with a hanging rope 13 at the two wiring holes, the top ends of the two hanging ropes 13 are respectively fixedly connected to the two winding drums 6, and the bottom ends of the two hanging ropes 13 are fixedly connected to the same clamping hoop 10, the clamping hoop 10 is sleeved on the outside of the screw conveyor 8, and the screw conveyor 8 can be installed using the clamping hoop 10, which not only facilitates the regular disassembly of the screw conveyor 8 for inspection and maintenance, but also allows the device to be suitable for use with different types of screw conveyors 8.

[0031] Preferably, the frame 1 is composed of two vertical bars and a horizontal bar at the top therebetween, the sleeve 12 is sleeved on the outside of the vertical bars, a threaded through hole is opened on one side of the sleeve 12, and the sleeve 12 is threadedly connected with a bolt 1201 at the threaded through hole, the bolt 1201 can maintain the height of the sleeve 12, so after adjusting the bending degree or height of the connecting bar 14, the sleeve 12 can be fixed with the bolt 1201 to maintain the state of the connecting bar 14, the connecting bar 14 is composed of an internal spring steel wire bundle and an externally wrapped rubber sleeve, the spring steel wire bundle can provide sufficient toughness for the connecting bar 14, so that it can provide sufficient support for the screw conveyor 8, and the rubber sleeve can protect the outside of the spring steel wire bundle and play a cushioning role for the screw conveyor 8.

[0032] Working principle: When the device is used, the position of the screw conveyor 8 can be adjusted by pushing the frame 1, so as to facilitate its movement and temporary installation;

[0033] When the position of the screw conveyor 8 is adjusted appropriately, the two motors 3 can be controlled to run respectively. After starting, the motor 3 can drive the worm wheel 4 to rotate through the worm 301, and the worm wheel 4 drives the winding drum 6 to rotate through the rotating shaft 5, so that the suspension rope 13 can be reeled and unreeled, thereby adjusting the end of the screw conveyor 8 to rise and fall through the hoop 10, so as to achieve its angle adjustment;

[0034] After the angle is adjusted appropriately, the position of the sliding sleeve 12 on the frame 1 can be adjusted after loosening the bolt 1201. When the positions of the two sliding sleeves 12 are moved at the same time, the height of the connecting strip 14 can be adjusted to ensure that the position of the connecting strip 14 corresponds to the screw conveyor 8. When only one sliding sleeve 12 is moved, the degree of deformation of the connecting strip 14 can be controlled to ensure that it can contact the outer wall of the screw conveyor 8 and produce an extrusion effect. In this case, the two connecting strips 14 can be used to clamp the screw conveyor 8 to achieve the effect of limiting and buffering.

[0035] Afterwards, materials can be fed into the screw conveyor 8 from the feed pipe for transportation.

[0036] Example 2

[0037] Refer to the attached Figure 4 The present application provides a screw conveyor for concrete production. Compared with Example 1, in order to ensure the smooth operation of the device and the integrity of material transportation, the screw conveyor 8 includes a shell, a spiral blade 801 and a drive assembly 802. The bottom end of the shell is fixedly connected to a cover shell 18, and a rotating rod 17 is rotatably connected to the inner wall of one side of the cover shell 18, and a circular through hole is opened on the other side of the cover shell 18, and the rotating rod 17 extends to the outside of the cover shell 18 at the circular through hole. The end of the rotating rod 17 and the output end of the driving component 802 are provided with the same transmission system 15, and the transmission system 15 is a belt transmission system. The rotating rod 17 is located in the cover 18, and a plurality of contact blocks 16 are fixedly connected to the outside of the rod body at equal intervals. The contact blocks 16 are conical, and the distance between the rotating rod 17 and the outer shell is smaller than the height of the contact blocks 16. Therefore, the contact blocks 16 will definitely hit the outer shell as the rotating rod 17 rotates. When the driving component 802 drives the spiral blade 801, it can synchronously drive the rotating rod 17 to rotate through the transmission system 15, and the rotating rod 17 can drive the contact blocks 16 to rotate to hit the outer shell, thereby causing the screw conveyor 8 to vibrate, thereby preventing excessive adhesion of materials inside it.

[0038] Working principle: During the operation of the screw conveyor 8, its driving component 802 can synchronously drive the rotating rod 17 to rotate through the transmission system 15 when driving the spiral blade 801. The rotating rod 17 can drive the contact block 16 to rotate so that its contact continuously hits the outer casing of the screw conveyor 8, thereby causing the screw conveyor 8 to vibrate. The vibration can be used to ensure the fluidity of the material and reduce its sticky effect inside the screw conveyor 8, thereby ensuring the smooth operation of the device and the integrity of material transportation.

[0039] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. The protection scope of the utility model should be based on the protection scope of the claims.
