Description

Technical Field

[0001] The utility model relates to the technical field of feeders, in particular to a cantilever screw feeder with end discharging. Background Art

[0002] The existing screw feeder has the following problems:

[0003] 1. The existing cantilever screw feeder adopts tail discharge, and the discharge port needs to be connected to the next equipment by a chute or buffer hopper (see Figure 5 ), which will have an impact on the height, resulting in an increase in the customer's civil engineering investment costs;

[0004] 2. The existing cantilever screw feeder has shaftless spiral blades and a bushing in the shell, which has a high manufacturing cost;

[0005] 3. The existing cantilever screw feeder has a limited length of spiral blades, otherwise there will be problems such as jumping and rubbing against the wall. Utility Model Content

[0006] The utility model aims to provide a cantilever screw feeder with end discharging in view of the defects and shortcomings of the prior art.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a cantilever screw feeder with end discharge, including a shell, and its innovation lies in: a feed port is opened on the top of the shell, a discharge port is opened at the end, a transmission shaft is arranged horizontally inside the shell, spiral blades are arranged on the transmission shaft, a hanging bearing is arranged on the side of the transmission shaft close to the discharge port, a bearing assembly and a transmission assembly are arranged on the end of the transmission shaft close to the feed port, and the transmission assembly is connected to the reduction motor for transmission.

[0008] Furthermore, the spiral blade is a variable pitch spiral blade, and the pitch of the spiral blade gradually increases between the feed inlet and the discharge outlet.

[0009] Furthermore, the transmission assembly includes a transmission sprocket or a coupling, the transmission sprocket is connected to the reduction motor through a chain transmission, and the coupling is directly connected to the reduction motor through a chain transmission.

[0010] After adopting the above structure, the utility model has the following beneficial effects:

[0011] The utility model adopts end discharging, and the material can directly enter the lifting equipment from the end. Compared with the traditional screw conveying equipment that discharges from the lower end of the tail and requires connecting parts such as slide pipes to connect to the lifting equipment, the utility model can reduce the equipment layout height and save investment costs; by adding hanging bearings and extending the length of the transmission shaft, the applicable working conditions of the equipment are greatly increased, and the stability of the equipment is further improved; a variable pitch design from small to large is adopted to avoid blockage of materials during spiral conveying, making the operation of the equipment more stable and convenient; there is no need to add a bushing inside the shell, which also avoids the friction between the spiral blades and the shell, reduces the manufacturing cost, and improves the performance of the equipment.

[0019] The utility model is further described below in conjunction with the accompanying drawings.

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and are not used to limit the utility model.

[0021] See also Figure 1-4A cantilever screw feeder with end discharge includes a housing 1, a feed port 2 is provided on the top of the housing 1, a discharge port 3 is provided at the end, a transmission shaft 4 is arranged horizontally inside the housing 1, a spiral blade 5 is arranged on the transmission shaft 4, a hanging bearing 6 is arranged on the side of the transmission shaft close to the discharge port, a bearing assembly 7 and a transmission assembly are arranged on the end of the transmission shaft 4 close to the feed port, and the transmission assembly is connected to a reduction motor 8. Specifically, the material can directly enter the next device from the discharge port 3 at the end (see Figure 4 ), thereby reducing the equipment layout height and saving investment costs; the use of hanging bearings 6 to extend the length of the transmission shaft greatly increases the applicable working conditions of the equipment and improves the stability of the equipment. At the same time, avoiding the use of bushings can not only prevent the spiral blades from rubbing against the shell, but also reduce manufacturing costs and improve the performance of the equipment; the hanging bearings 6 can prevent the transmission shaft from shaking due to excessive length and affect the operation of the screw conveyor; the reduction motor 8 rotates the transmission shaft 4 through the transmission assembly, thereby achieving the purpose of spiral conveying, and the bearing assembly 7 enables the screw conveyor to form a cantilever structure, so that the material at the feed port 2 can be discharged from the end discharge port 3 to the next device under the rotation of the transmission shaft 4 with spiral blades, thereby reducing the equipment layout height and saving investment costs.

[0022] In this embodiment, the spiral blade 5 is a variable pitch spiral blade, and the pitch of the spiral blade gradually increases between the feed inlet and the discharge outlet, so as to facilitate material transportation and prevent material from being blocked during the spiral transportation process.

[0023] In this embodiment, the transmission assembly includes a transmission sprocket 9 or a coupling 10, and the transmission sprocket 9 is connected to the reduction motor 8 through a chain drive (see Figure 2 ), the coupling 10 is directly connected to the reduction motor 8 (see Figure 3 ). The transmission mode can be selected according to the specific situation.

[0024] The above description is only used to illustrate the technical solution of the utility model rather than to limit it.
