Description

Technical Field

[0001] The utility model relates to the technical field of conveying augers, and particularly relates to an intermediate support for a conveying auger. Background Art

[0002] Conveying augers are often used to convey powdery feed. The conveying auger includes a housing, an auger shaft provided with spiral blades in the housing, and a motor for driving the rotation of the auger shaft. Through the rotation of the auger shaft, the conveyance of the feed is realized. However, when the conveying line is relatively long, a plurality of auger shafts need to be connected together. Welding is often used. Welding connection does not require additional connecting parts or intermediate parts. Only two auger shafts need to be directly welded together. The structure is relatively simple, reducing the number and complexity of parts. At the same time, the welding process can usually be carried out in a factory or on-site, without the need for complex processing equipment or processes, and the processing process is relatively convenient and fast.

[0003] However, this method has the following disadvantages: 1. During the welding process, due to the influence of high temperature and welding stress, the center position of the auger shaft is likely to shift, thereby affecting the overall vibration characteristics and running stability of the equipment. 2. During the welding process, defects such as pores, slag inclusions, and lack of fusion will appear. These defects may become the starting points of cracks, thereby affecting the service life of the auger shaft. Summary of the Utility Model

[0004] Based on this, in view of the above problems, the utility model provides an intermediate support for a conveying auger.

[0005] The purpose of the utility model can be realized by the following technical solutions:

[0006] An intermediate support for a conveying auger, the conveying auger includes a housing and a plurality of coaxially arranged auger shafts provided in the housing. The intermediate support includes a rotating shaft for connecting two adjacent auger shafts, a sleeve sleeved on the rotating shaft, a wear-resistant member is provided between the sleeve and the rotating shaft, a support plate is provided in the housing above the sleeve, and the sleeve is installed on the support plate through a connecting rod.

[0007] By adopting the above technical solution, two adjacent auger shafts are connected together through the rotating shaft, thus meeting the requirements of a long conveying line and having a low cost. By sleeving the sleeve on the rotating shaft, providing a support plate above the sleeve, and fixing the sleeve on the support plate, the rotating shaft can be supported to ensure the smooth progress of the conveying process. By providing a wear-resistant member between the sleeve and the rotating shaft, the frictional resistance can be reduced.

[0008] In a specific embodiment of the utility model: an elevation adjustment structure for adjusting the elevation of the sleeve is provided between the support plate and the connecting rod.

[0009] In the specific embodiment of the present utility model: the lifting and adjusting structure includes a first nut and a second nut. Both ends of the connecting rod have external threads. A perforation is provided on the support plate at the position corresponding to the connecting rod. A connecting head is provided on the outer circumferential surface of the sleeve at the position corresponding to the connecting rod. An internal thread is provided on the inner wall of the connecting head. The upper end of the connecting rod passes through the perforation and is clamped and fixed by two first nuts sleeved on the upper end of the connecting rod. The lower end passes through the second nut and is threadedly connected to the connecting head. With this structure, by adjusting the position of the connecting rod up and down, the up and down position of the sleeve is driven to adjust, thereby realizing the coaxial adjustment of the rotating shaft and the two auger shafts.

[0010] In the specific embodiment of the present utility model: the wear-resistant member is a nylon sleeve.

[0011] In the specific embodiment of the present utility model: the sleeve is composed of two upper and lower semi-circular tubes.

[0012] In the specific embodiment of the present utility model: the semi-circular tube is divided into an intermediate arc portion and horizontal connecting portions located on both sides of the arc portion.

[0013] In the specific embodiment of the present utility model: the support plate includes a horizontal plate and vertical plates connected to the two short edges of the horizontal plate.

[0014] In summary, the two auger shafts are connected by a rotating shaft, thus meeting the requirements of a long conveying line and having a low cost. Among them, by sleeving the sleeve on the rotating shaft and arranging a support plate above the sleeve to fix the sleeve on the support plate, the rotating shaft is supported to ensure the smooth progress of the conveying process. In addition, by arranging a nylon sleeve between the sleeve and the rotating shaft, since the friction coefficient between the nylon sleeve and the rotating shaft is small, only a small amount of power is required to drive the rotating shaft, with low energy consumption; moreover, the cost of the nylon sleeve is low, and it can be directly replaced when the nylon sleeve is worn and damaged. In addition, by adjusting the position of the connecting rod up and down, the up and down position of the sleeve is driven to adjust, thereby realizing the coaxial adjustment of the rotating shaft and the two auger shafts, making the transmission process smoother and improving the transmission efficiency.

[0020] 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 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.

[0021] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the present utility model is an intermediate support member of a conveying auger. The conveying auger 10 includes a housing 11, a plurality of coaxially arranged auger shafts 12 provided in the housing 11, and a motor 13 for driving the rotation of the auger shafts 12. The intermediate support member 20 includes a rotating shaft 21 for connecting two adjacent auger shafts 12, and a sleeve 22 sleeved on the rotating shaft 21. A wear-resistant member 23 is provided between the sleeve 22 and the rotating shaft 21. In this embodiment, the wear-resistant member 23 is a nylon sleeve. By providing a nylon sleeve between the sleeve 22 and the rotating shaft 21, since the friction coefficient between the nylon sleeve and the rotating shaft is small, therefore, only a relatively small power is required to drive the rotating shaft, and the energy consumption is low; moreover, the cost of the nylon sleeve is low, and when the nylon sleeve is worn and damaged, it can be directly replaced. For the convenience of installation, the nylon sleeve can be divided into two semi-circles.

[0022] As Figure 4 shown, a support plate 24 is provided above the sleeve 22 in the housing 11. The sleeve 22 is installed on the support plate 24 through a connecting rod 25. In this embodiment, the support plate 24 is an integrally formed structure, including a horizontal plate 241 and vertical plates 242 connected to two short edges of the horizontal plate. The two vertical plates 242 are respectively fixed to the inner wall of the housing by screws.

[0023] An elevation adjustment structure for adjusting the elevation of the sleeve 22 is provided between the support plate 24 and the connecting rod 25.

[0024] In this embodiment, the lifting and adjusting structure includes a first nut 26 and a second nut 27. Both ends of the connecting rod 25 have external threads. A perforation 243 is provided at the position corresponding to the connecting rod 25 on the support plate 24. A connecting head 221 is provided on the outer circumferential surface of the sleeve 22 at the position corresponding to the connecting rod 25, and internal threads matching the external threads are provided on the inner wall of the connecting head 221. The upper end of the connecting rod 25 passes through the perforation 243 and is clamped and fixed by two first nuts 26 sleeved on the upper end of the connecting rod. The lower end passes through the second nut 27 and is threadedly connected to the connecting head 221. By adjusting the position of the connecting rod up and down, the up and down position of the sleeve 22 is driven to adjust, thereby realizing the coaxial adjustment of the rotating shaft and the two auger shafts.

[0025] In this embodiment, the sleeve 22 is composed of two semi-circular tubes connected together by bolts. Each semi-circular tube is divided into an intermediate arc portion 222 and horizontal connecting portions 223 located on both sides of the arc portion 222.

[0026] During assembly, the rotating shaft 21 connects the two auger shafts together by bolts. Subsequently, a nylon sleeve is sleeved on the rotating shaft 21. Then, the upper and lower semi-circular tubes are sleeved on the nylon sleeve and fixed together by bolts. Subsequently, the support plate 24 is fixed in the housing 11 by screws and is located above the sleeve 22. The lower end of the connecting rod 25 passes through the second nut 27 and is threadedly connected to the connecting head 221 of the sleeve 22. After the upper end passes through the perforation 243 on the support plate 24, the position of the connecting rod 25 is adjusted by rotating it up and down to drive the up and down position adjustment of the sleeve 22, thereby realizing the coaxial adjustment of the rotating shaft and the two auger shafts. After the adjustment is in place, the second nut is tightened for fixation, and the two first nuts sleeved on the upper end of the connecting rod 25 are used for clamping and fixing.

[0027] In summary, the two auger shafts are connected by the rotating shaft to meet the requirements of a long conveying line. Among them, by sleeving the sleeve on the rotating shaft, setting a support plate above the sleeve, and fixing the sleeve on the support plate, the rotating shaft can be supported to ensure the smooth progress of the conveying process. In addition, by setting a nylon sleeve between the sleeve and the rotating shaft, since the friction coefficient between the nylon sleeve and the rotating shaft is small, only a small amount of power is required to drive the rotating shaft, resulting in low energy consumption; moreover, the cost of the nylon sleeve is low, and it can be directly replaced when the nylon sleeve is worn or damaged. In addition, by adjusting the position of the connecting rod up and down, the up and down position of the sleeve is driven to adjust, thereby realizing the coaxial adjustment of the rotating shaft and the two auger shafts, making the transmission process smoother and improving the transmission efficiency.
