Description

Technical Field

[0001] The utility model belongs to the technical field of screw conveyors, and particularly relates to an intermediate connector for a screw conveyor and the conveyor thereof. Background Technique

[0002] A screw conveyor is a machine that uses an electric motor to drive a screw to rotate and push materials to achieve the purpose of conveying. It is widely used in various industries, such as metallurgy, chemical industry, food, building materials, machinery, electric power, light industry, medicine, etc. The screw conveyor has a wide range of applications in many industries. For example, in the food industry, the screw conveyor can be used to convey various grains, feeds, sugars, etc.; in the chemical industry, it can be used to convey various chemical raw materials, catalysts, etc.; in the pharmaceutical industry, it can be used to convey drugs, vaccines, etc.; in the building materials industry, it can be used to convey various cements, mortars, etc. It is an indispensable material conveying equipment in modern industrial production.

[0003] However, the designed length of the existing tubular screw conveyor is usually controlled within five meters. This is because as the length of the conveyor increases, the screw shaft inside the pipe is prone to bending or sagging due to its own weight and the pressure exerted when conveying materials, and then unnecessary friction occurs with the pipe wall. This friction will not only reduce the conveying efficiency, but may also accelerate the wear of the equipment and even cause failures, resulting in certain limitations in the length of the existing tubular screw conveyor and making it difficult to meet the growing industrial production needs.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] Embodiment 1:

[0028] Please refer to Figure 1 - Figure 4 as shown, a spiral conveyor intermediate connector and its conveyor include:

[0029] The connector body 1 is installed at both ends of the conveyor body 2. There are two conveyor bodies 2, and several connecting bolts 3 are provided on the connector body 1. Connecting nuts 4 are threadedly connected to several connecting bolts 3;

[0030] The connector body 1 is installed between the opposite surfaces of the two conveyor bodies 2, and the connector body 1 can realize the connection and extension between the two conveyor bodies 2;

[0031] The connector body 1 includes a connector housing 11, a connecting mechanism 12, a connecting ring 13 and a connecting hole 14. There are two connector housings 11. The connecting mechanism 12 is installed on the inner wall of the upper connector housing 11. There are four connecting rings 13, and the four connecting rings 13 are respectively installed on both sides of the outer walls of the two connector housings 11. The connecting hole 14 is opened on the outer wall of the connecting ring 13.

[0032] From Figure 2 and Figure 3 it can be seen that two reinforcing plates 15 are jointly installed between the opposite surfaces of the two upper connecting rings 13 and between the opposite surfaces of the two lower connecting rings 13. Two reinforcing holes 16 are opened at the top ends of the four reinforcing plates 15, and a reinforcing screw 17 is jointly inserted and movably connected between the upper reinforcing hole 16 and the corresponding lower reinforcing hole 16. Reinforcing nuts 18 are threadedly connected to the upper and lower outer surfaces of the four reinforcing screws 17;

[0033] The connecting mechanism 12 includes a suspension rod 121, a fixing ring 122, a bearing 123, a connecting shaft 124 and a reinforcing tooth groove 125. The top end of the suspension rod 121 is fixedly connected to the inner wall of the upper connector housing 11. The fixing ring 122 is arranged at the bottom end of the suspension rod 121. The bearing 123 is installed on the inner wall of the fixing ring 122. The connecting shaft 124 is installed on the inner wall of the bearing 123. The reinforcing tooth groove 125 is opened on the outer surface of the connecting shaft 124.

[0034] As can be seen from the above, when it is necessary to lengthen the length of the screw conveyor, the connector body 1 can be used to connect two conveyor bodies 2 together. By installing the connecting shaft 124 with two screw shafts 23, and through the support of the suspension rod 121 and the rotation of the bearing 123, while firmly supporting the screw shaft 23, it is also allowed to rotate freely within a certain range, so that the connecting shaft 124 can bear the weight of the screw shaft 23 and the stress during operation. Then, by passing the reinforcement screw 17 through the corresponding two reinforcement holes 16, and then sleeving two reinforcement nuts 18 on the reinforcement screw 17 and tightening them, two adjacent reinforcement plates 15 can be installed together to achieve the firm and tight installation of the two connector shells 11. By using the connector body 1, when lengthening the screw conveyor, the problem that the screw shaft 23 inside it bends and sags and rubs against the pipe wall can be solved, which can reduce wear and failures, and further improve the operation stability and service life of the screw conveyor, and can also meet the growing industrial production needs.

[0035] Specifically, referring to Figure 2 and Figure 3 As shown, the connecting shaft 124 is located at the central position of the connector body 1. A protrusion is provided in the middle of the outer surface of the connector shell 11. The connecting ring 13 is set as an arc structure, and an integral structure is provided between the connecting ring 13 and the reinforcement plate 15.

[0036] As can be seen from the above, the connecting shaft 124 and the two screw shafts 23 are both located at the same center point, so that there will be no deviation in the connection position between the connecting shaft 124 and the two screw shafts 23. The connector shell 11 with a middle protrusion can bear various mechanical loads transmitted from the suspension rod 121 to ensure its stability and durability. The arc-shaped connecting ring 13 can fit with the outer surface of the connector shell 11, which can strengthen the firmness between the connecting ring 13 and the reinforcement plate 15.

[0037] Embodiment 2:

[0038] Referring to Figure 4 As shown, the conveyor body 2 includes a conveyor shell 21, a connecting flange 22, a screw shaft 23, a screw blade 24 and a connecting groove 25. The connecting flange 22 is installed on the outer surface of the conveyor shell 21. The screw shaft 23 is arranged inside the conveyor shell 21. The screw blade 24 is arranged on the outer surface of the screw shaft 23. The connecting groove 25 is opened on the end face of the screw shaft 23 near the connector body 1.

[0039] As described above, by inserting the connecting shaft 124 into the connecting groove 125 and through the precise clamping between several racks on the inner wall of the connecting groove 25 and several reinforcing tooth grooves 25 on the outer surface of the connecting shaft 124, the spiral shaft 23 and the connecting shaft 124 can be firmly installed and connected. Then, by passing the connecting bolt 3 through the connecting hole 14 and inserting it into the connecting flange 22, and slipping the connecting nut 4 onto the connecting bolt 3 and tightening it, the connecting flange 22 and the connecting ring 13 can be fixedly connected, and thus the conveyor housing 21 and the connector housing 11 can be closely installed together, so as to achieve the firm installation between the two conveyor bodies 2 and the connector body 1. Therefore, in the actual application of the screw conveyor, the length of the screw conveyor can be extended to form an extended material conveying system. Through the perfect combination of the screw conveyor and the intermediate connector, not only the technical problems in long-distance conveying are solved, but also the operation efficiency and reliability of the equipment are significantly improved, providing strong support for the material conveying in various industrial fields.

[0040] Preferably, as shown in Figure 4 , the connecting flange 22 is installed together with two corresponding connecting rings 13 through the connecting bolt 3 and the connecting nut 4, and several racks are provided on the groove wall of the connecting groove 25.

[0041] As described above, the firm and sealed installation between the connector body 1 and the conveyor body 2 can be achieved. By making several racks just insert into the corresponding several reinforcing tooth grooves 125, the firm connection between the spiral shaft 23 and the connecting shaft 124 can be realized.

[0042] 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. The scope of the present invention is defined by the appended claims and their equivalents.
