Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with embodiments.

[0023] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0024] In the embodiments, unless otherwise specified, all methods used are conventional methods in the art.

[0025] Please see Figures 1-4 This application provides a multi-stage screening device for cottonseed processing, including a screening component 100 and a cleaning component 200.

[0026] Please see Figure 1 , 2 3. The screening assembly 100 includes a base plate 110, a first support frame 120, a first screening cylinder 130, a second support frame 140, a second screening cylinder 150, and a drive motor 160. The first support frame 120 is disposed on the top of the base plate 110, and the first screening cylinder 130 rotatably passes through the first support frame 120. The second support frame 140 is disposed on the top of the base plate 110, and the second screening cylinder 150 rotatably passes through the second support frame 140. The drive motor 160 is installed on the side of the first support frame 120 and is connected to the first screening cylinder 130 and the second screening cylinder 150.

[0027] The second screening cylinder 150 passes through the first screening cylinder 130, and the first screening cylinder 130 and the second screening cylinder 150 are arranged at an angle. By setting the first screening cylinder 130 and the second screening cylinder 150 at an angle, the cotton seeds are first screened through the second screening cylinder 150, and the smaller ones pass through the second screening cylinder 150 and enter the first screening cylinder 130, and are screened again through the first screening cylinder 130. The screen hole size of the first screening cylinder 130 is smaller than the screen hole size of the second screening cylinder 150.

[0028] Specifically, the output end of the drive motor 160 is fixedly connected to the drive gear 161, and the first screening cylinder 130 is fixedly sleeved with the gear ring 131. The drive gear 161 and the gear ring 131 mesh with each other. By setting the drive gear 161 and the gear ring 131 to mesh, the drive motor 160 is started to drive the drive gear 161 to rotate. The drive gear 161 meshes and drives the gear ring 131 to rotate. The gear ring 131 drives the first screening cylinder 130 to rotate.

[0029] Specifically, the output end of the drive motor 160 is fixedly connected to the first pulley 162, and the second screening cylinder 150 is fixedly sleeved with the second pulley 151. The first pulley 162 and the second pulley 151 are connected by a synchronous belt drive. By setting the first pulley 162 and the second pulley 151, the drive motor 160 is started to drive the first pulley 162 to rotate. The first pulley 162 drives the second pulley 151 to rotate through the belt. The second pulley 151 drives the second screening cylinder 150 to rotate.

[0030] It should be noted that the first screening cylinder 130 and the second screening cylinder 150 rotate in opposite directions, and both the first screening cylinder 130 and the second screening cylinder 150 are provided with sieve holes. By setting the first screening cylinder 130 and the second screening cylinder 150 to rotate in opposite directions, the screening efficiency of cottonseed is effectively improved.

[0031] In one specific implementation, the top of the base plate 110 is provided with a plurality of receiving boxes 180, and the top of the receiving boxes 180 is hollowed out. By providing a plurality of receiving boxes 180, the cotton seeds to be screened are collected separately.

[0032] In this embodiment, a feeding hopper 190 is provided on the top of the bottom plate 110. The feeding hopper 190 is inclined toward the second screening cylinder 150. By providing the feeding hopper 190 inclined toward the second screening cylinder 150, it is convenient to add cottonseed into the second screening cylinder 150.

[0033] Please see Figure 1 , 2 3 and 4, the cleaning assembly 200 includes a fixing rod 210 and a cleaning brush 220. The fixing rod 210 is fixedly connected to the second support frame 140 and passes through the first screening cylinder 130 and the second screening cylinder 150. The cleaning brush 220 is fixedly connected to the fixing rod 210.

[0034] The cleaning brush 220 is located between the first screening cylinder 130 and the second screening cylinder 150, and the end of the cleaning brush 220 abuts against the first screening cylinder 130 and the second screening cylinder 150. The cleaning brush 220 arranged between the two screening cylinders can remove the cotton seeds stuck in the screen holes.

[0035] The working principle of this multi-stage screening device for cottonseed processing is as follows: During use, cottonseed is added to the second screening cylinder 150 through the feeding hopper 190. The drive motor 160 is started, driving the drive gear 161 to rotate. The drive gear 161 meshes and drives the gear ring 131 to rotate, which in turn drives the first screening cylinder 130 to rotate. Simultaneously, the drive motor 160 drives the first pulley 162, which in turn drives the second pulley 151 via a belt. The second pulley 151 then drives the second screening cylinder 150 to rotate. Furthermore, the first and second screening cylinders 130 rotate in opposite directions, effectively improving the screening efficiency of the cottonseed. During the screening process, a cleaning brush 220 positioned between the first and second screening cylinders 130 and 150 removes cottonseed stuck in the screen holes, effectively ensuring the screening effect and improving screening efficiency.

[0036] It should be noted that the specific model and specifications of the drive motor 160 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0037] The power supply and principle of the drive motor 160 are clear to those skilled in the art and will not be described in detail here.

[0038] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
