Description

Technical Field

[0001] This utility model belongs to the field of cottonseed processing technology, specifically a cottonseed feeding and impurity removal device. Background Technology

[0002] Cottonseed is a crucial product in the cotton planting and processing industry. After harvesting, cottonseed often contains various impurities. These impurities are mainly due to contamination from the cotton's growing environment and during harvesting and transportation. During harvesting, these impurities are easily collected along with the cottonseed. Furthermore, during harvesting, cotton may be contaminated with cotton leaves, stalk fragments, and even metal fragments from agricultural tools, such as scissor pieces and screws. Therefore, there is a pressing need in the market for a cottonseed feeding and impurity removal device.

[0003] Meanwhile, the patent specification with application number CN214184092U discloses a cottonseed feeding and impurity removal device, which "includes a wind-powered seed cleaner, an auger screen, a hopper, a discharge port, a turning wheel, and an impurity outlet. The discharge port is installed at the bottom of the hopper, and the bottom of the discharge port is connected to the feed port of the auger screen. The turning wheel is installed in the middle of the discharge port, and the impurity outlet is installed on one side of the auger screen and located on the side close to the discharge port."

[0004] Existing cottonseed impurity removal devices mostly use a single screen, which is difficult to distinguish impurities with particle sizes similar to cottonseed. The mixing of impurities affects the stability and continuity of the production process, interferes with cottonseed conveying during feeding, and aggravates equipment wear and reduces product quality during processing. Secondly, the screening methods are limited, mostly using static screens or air screening. Static screens are prone to impurity accumulation due to the lack of external force, which hinders contact between cottonseed and the screen. Air screening is not ideal for removing impurities with particle sizes and weights similar to cottonseed. In oil pressing, residual impurities will reduce oil quality and affect equipment operation.

[0005] Therefore, a cottonseed feeding and impurity removal device is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a cottonseed feeding and impurity removal device, which has the advantages of effectively identifying impurities of similar particle size, improving product quality and impurity removal quality while ensuring stable production operation, and providing higher quality cottonseed for subsequent processing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cottonseed feeding and impurity removal device, comprising a mounting box, wherein a vibration screening mechanism is provided on the inner surface of the mounting box, the vibration screening mechanism includes a servo motor, the servo motor is fixedly connected to the mounting box, a rotating plate is fixedly connected to the output end of the servo motor, four inclined blocks are fixedly connected to the top end of the rotating plate, a screen box is provided at the top end of the mounting box, four connecting rods are fixedly connected to the bottom end of the screen box, the bottom ends of the four connecting rods all penetrate the mounting box and are slidably connected to the mounting box, and a rubber roller is fixedly connected to one end of each of the four connecting rods located inside the mounting box.

[0008] Preferably, all four rollers are located at the top of the rotating plate, and the rollers and the four inclined blocks are located on the circumference of the same circular profile.

[0009] Preferably, four sliding rods are fixedly connected to the bottom end of the rotating plate, and the four sliding rods are arranged in a circular array. The lower inner wall of the mounting box is provided with an annular groove for use with the sliding rods.

[0010] Preferably, two shock-absorbing rings are fixedly connected to the outer surface of each of the four connecting rods, and the four shock-absorbing rings on the same horizontal side are located on the upper and lower sides of the top of the mounting box, respectively.

[0011] Preferably, the inner surface of the screen box is provided with screen one and screen two, and one end of screen one and screen two are provided with handles. Screen one is located directly above screen two. Guide strips are fixedly connected to both ends of screen one and screen two. The inner walls on both sides of the screen box are provided with guide grooves that cooperate with four guide strips. The four guide grooves are respectively damped and slidably connected to the four guide strips.

[0012] Preferably, the aperture of the first sieve is larger than that of the second sieve, and the aperture of the second sieve is adapted to the cottonseed.

[0013] Preferably, an inclined plate is fixedly connected to the lower inner wall of the screen box, and an impurity discharge frame is fixedly connected to one end of the screen box. The lower inner wall of the impurity discharge frame is inclined and has the same inclination angle as the inclined plate. A collection box is placed directly below the impurity discharge frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model sets up a first screen and a second screen. The first screen is used to screen impurities with a particle size larger than cottonseed, while the second screen is used to screen impurities with a particle size smaller than cottonseed. Compared with the traditional single screen, it can separate cottonseed and impurities more finely, thereby significantly improving the quality and effect of impurity removal, ensuring higher purity of cottonseed after screening, effectively identifying impurities with similar particle sizes, and improving product quality while ensuring stable production operation.

[0016] 2. This utility model, by setting up a vibration screening mechanism, drives the screen box to vibrate up and down under the action of a servo motor. This vibration mode allows cottonseeds to tumble and jump fully on the screen, avoiding the accumulation of impurities and greatly improving screening efficiency. At the same time, the device can also effectively separate impurities that are difficult to remove by wind screening, which are similar in size and weight to cottonseeds, thus improving the quality of impurity removal and providing higher quality cottonseeds for subsequent processing.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 4 As shown, this utility model provides a cottonseed feeding and impurity removal device, including a mounting box 1. The mounting box 1 serves as the main structure and provides installation and support space for other components. The inner surface of the mounting box 1 is provided with a vibration screening mechanism 3.

[0027] The vibration screening mechanism 3 includes a servo motor 32, which is fixedly connected to the mounting box 1. A rotating plate 33 is fixedly connected to the output end of the servo motor 32. Four inclined blocks 38 are fixedly connected to the top of the rotating plate 33. A screen box 5 is provided at the top of the mounting box 1. Four connecting rods 37 are fixedly connected to the bottom of the screen box 5. The bottom ends of the four connecting rods 37 all penetrate the mounting box 1 and are slidably connected to the mounting box 1. A rubber roller 35 is fixedly connected to one end of each of the four connecting rods 37 inside the mounting box 1. The vibration screening mechanism 3 is set inside the mounting box 1 to screen and remove impurities from cotton seeds.

[0028] Specifically, all four rollers 35 are located at the top of the rotating plate 33, and the rollers 35 and the four inclined blocks 38 are all located on the circumference of the same circular contour. This ensures that when the rotating plate 33 rotates, the rollers 35 can move regularly under the action of the inclined blocks 38, so that the screen box 5 generates stable vibration, which is conducive to better screening of cotton seeds on the screen, improving the impurity removal efficiency and screening uniformity.

[0029] like Figures 1 to 4 As shown, four sliding rods 31 are fixedly connected to the bottom end of the rotating plate 33. The four sliding rods 31 are arranged in a ring array. The lower inner wall of the mounting box 1 is provided with an annular groove 34 that works with the sliding rods 31. This groove stabilizes and guides the rotating plate 33, preventing it from shifting or shaking during rotation. This ensures the stable operation of the entire vibrating screening mechanism 3 and reduces errors and malfunctions caused by shaking.

[0030] Furthermore, two shock-absorbing rings 36 are fixedly connected to the outer surfaces of the four connecting rods 37. The four shock-absorbing rings 36 on the same horizontal side are located on the upper and lower sides of the top of the mounting box 1, respectively. The shock-absorbing rings 36 can reduce the impact force on the mounting box 1 generated by the connecting rods 37 during the up and down movement, and reduce the noise and vibration generated during the operation of the device.

[0031] like Figures 1 to 4 As shown, the inner surface of the screen box 5 is provided with a first screen 53 and a second screen 55. Each of the first screen 53 and the second screen 55 has a handle 54 at one end. The first screen 53 is located directly above the second screen 55. Guide strips 56 are fixedly connected to both ends of the first screen 53 and the second screen 55. The inner walls on both sides of the screen box 5 are provided with guide grooves 51 that cooperate with the four guide strips 56. The four guide grooves 51 are respectively connected to the four guide strips 56 with damping sliding. The first screen 53 and the second screen 55 can perform multi-stage screening of cottonseeds. Different apertures can separate impurities of different sizes. The damping sliding connection between the guide strips 56 and the guide grooves 51 makes the screen stable in position during use and prevents it from shaking randomly, thus ensuring the accuracy of screening.

[0032] It is worth noting that the aperture of the first screen 53 is larger than that of the second screen 55, and the aperture of the second screen 55 is adapted to the cottonseed. This design allows for the removal of larger impurities first through the first screen 53, and then further screening of impurities similar in size to the cottonseed through the second screen 55, thereby improving the accuracy of impurity removal and resulting in higher quality cottonseed after screening.

[0033] like Figures 1 to 4 As shown, an inclined plate 52 is fixedly connected to the lower inner wall of the screen box 5, and an impurity discharge frame 2 is fixedly connected to one end of the screen box 5. The lower inner wall of the impurity discharge frame 2 is inclined and has the same inclination angle as the inclined plate 52. A collection box 4 is placed directly below the impurity discharge frame 2. The inclined plate 52 and the inclined impurity discharge frame 2 facilitate the smooth discharge of impurities under the action of gravity. The collection box 4 can conveniently collect impurities, prevent impurities from scattering, keep the working environment clean, and also facilitate subsequent processing of impurities.

[0034] The servo motor 32 is existing technology and will not be described in detail. This invention also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this invention is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0035] Working principle and process: When cottonseed needs to be cleaned, the cottonseed to be cleaned is first poured into screen 53 of the screen frame. Then, the servo motor 32 is started. The output of the servo motor 32 drives the rotating plate 33 to rotate. The four inclined blocks 38 at the top of the rotating plate 33 move in a circular motion with the rotating plate 33. When the inclined blocks 38 rotate, they periodically contact the rollers 35 and generate an interaction force, causing the screen box 5 to vibrate up and down. The four sliding rods 31 and the annular groove 34 at the bottom of the rotating plate 33 play a stabilizing and guiding role in the rotation of the rotating plate 33, ensuring the smoothness of the rotation process. During the vibration of the screen box 5, the cottonseed is screened on screen 53 and screen 55 inside the screen box 5. In the selection process, cottonseeds first fall onto screen 53. Since the aperture of screen 53 is larger than that of screen 55, larger impurities are intercepted by screen 53. Cottonseeds and smaller impurities after being screened by screen 53 continue to fall onto screen 55. Because the aperture of screen 55 is adapted to the cottonseeds, even smaller impurities fall through screen 55, while the cottonseeds that meet the requirements remain on screen 55. The impurities that have been screened slide down the inclined plate 52 on the lower inner wall of the screen box 5 onto the impurity discharge rack 2. Since the lower inner wall of the impurity discharge rack 2 is inclined and has the same inclination angle as the inclined plate 52, the impurities slide down the impurity discharge rack 2 under the action of gravity and finally fall into the collection box 4 directly below, completing the impurity collection and cottonseed removal process.
