Description

Technical Field

[0001] This utility model relates to the field of cottonseed processing technology, specifically to a cottonseed dehulling device. Background Technology

[0002] The commercial importance of cottonseed, as the seed of a plant in the genus Gossypium of the Malvaceae family, lies in its oil and other products. For example, cottonseed oil can be used in salad oil and edible oil, and after hydrogenation, it can be used to make ghee and margarine. The cake residue or kernels produced after oil extraction can be used as feed for poultry and livestock, making it widely used.

[0003] Currently, to ensure the efficiency of cottonseed processing, researchers in related fields have disclosed some devices for cottonseed dehulling, such as the commonly used drum dehulling machine. This machine uses the friction between the relatively rotating drum and the toothed plates on the drum surface to separate the cottonseed hull from the kernel, thereby achieving automatic dehulling. However, the applicant found in actual use that existing drum dehulling machines usually only have one pair of working drums. But in reality, cottonseeds vary in size and the pressure they experience during dehulling is also different. Therefore, in actual operation, some cottonseeds are easily not completely dehulled, resulting in significant defects in processing quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cottonseed dehulling device, which solves the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a cottonseed dehulling device, including a dehulling box and a support frame installed on the outer side of the dehulling box. The bottom of the dehulling box is provided with a discharge port. The interior of the dehulling box is fitted with two first dehulling tooth cylinders and two second dehulling tooth cylinders respectively. The two first dehulling tooth cylinders and the two second dehulling tooth cylinders are arranged in a one-to-one manner. Adjacent first dehulling tooth cylinders and second dehulling tooth cylinders form a meshing and dehulling space. The size of the two meshing and dehulling spaces decreases from top to bottom.

[0006] One end of each of the two first shelling cylinders extends to the outer side of the front end of the shelling box, and one end of each of the two second shelling cylinders extends to the outer side of the rear end of the shelling box. The front end and the rear end of the shelling box are respectively provided with a first meshing output component and a second meshing output component. The first meshing output component and the second meshing output component can respectively drive the output of the two first shelling cylinders and the two second shelling cylinders, thereby enabling the adjacent first shelling cylinders and second shelling cylinders to rotate relative to each other.

[0007] Specifically, the first meshing output assembly includes two first transmission gears, the output ends of which are respectively connected to one end of two corresponding first unscrewing gear cylinders, and a first fixing seat is installed between the housing surface of the two first transmission gears and the front end surface of the unscrewing box. The second meshing output assembly includes two first servo motors, the output ends of which are respectively connected to one end of two corresponding second unscrewing gear cylinders, and a second fixing seat is installed between the housing surface of the two first servo motors and the rear end surface of the unscrewing box.

[0008] In this preferred embodiment, clearance spaces are provided between the two first dehulling toothed cylinders and between the two second dehulling toothed cylinders, and guide baffles are installed in both clearance spaces. One side of each guide baffle is set as an inclined structure facing the discharge port, and the two guide baffles are used to assist in guiding the falling movement of the material.

[0009] Preferably, the surfaces of the two first unscrewing cylinders and the two second unscrewing cylinders are provided with a wear-resistant coating, and the wear-resistant coating can be selected as a hard alloy coating, thereby improving the wear resistance of the two first unscrewing cylinders and the two second unscrewing cylinders.

[0010] Preferably, a feeding bin is fitted inside the top of the shelling box, and elastic limiting rods are provided between one side of the middle of the feeding bin and one side of the top of the shelling box, and between the other side of the middle of the feeding bin and the other side of the top of the shelling box. A cam transmission assembly is provided between the feeding bin and the shelling box, and a discharge port is opened at the bottom of the shelling box, which is aligned with the meshing and shelling space closest to the top port of the shelling box.

[0011] The preferred elastic limiting rod includes a T-shaped rod and a buffer spring. The two ends of the T-shaped rod are respectively snapped onto the corresponding side of the feeding bin and fixedly connected to the top surface of the shelling box. The two ends of the buffer spring are respectively fixedly connected to the surface of the corresponding side of the feeding bin and the surface of the top of the shelling box. The elastic limiting rod serves as a support condition, enabling the feeding bin and the shelling box to be used stably as a whole.

[0012] Selectedly, the cam transmission assembly includes a second servo motor and a cam block body. The output end of the second servo motor is connected to the cam block body for transmission, and the cam block body can reciprocate to press the feeding bin under the synchronous rotation output of the second servo motor, thereby vibrating the feeding bin to prevent blockage and improve the efficiency of use.

[0013] Specifically, a space adjustment component is provided inside the discharge port. The space adjustment component includes an adjustment plate, the two ends of which are movably connected to the front and rear end structures of the bottom of the feeding hopper. One end of the adjustment plate passes through the outer front end of the feeding hopper and is connected to a second transmission gear. An electric push rod is installed on the front surface of the feeding hopper. The output end of the electric push rod is connected to a straight gear plate that can be driven by the second transmission gear. Under the transmission output of the electric push rod through the second transmission gear and the straight gear plate, the adjustment plate can rotate to close or rotate to open the discharge port. By using the space adjustment component to open or close the discharge port, a relatively quantitative discharge adjustment can be achieved, further optimizing the overall performance of the device.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, through the combination of two first dehulling cylinders, two second dehulling cylinders, and their respective corresponding first meshing output components and second meshing output components with the dehulling box, can perform multi-stage meshing dehulling of cotton seeds, fully ensuring the processing quality of cotton seeds and solving the problems existing in the prior art.

[0016] 2. This utility model is a multi-functional feeding device composed of a feeding bin, multiple elastic limiting rods, and a cam transmission assembly. When used in conjunction with a shelling box, it can meet the needs of large-volume feeding while also using the cam transmission assembly to reciprocate the impact of the feeding bin and using the limiting guidance of multiple elastic limiting rods to perform vibration and anti-blocking adjustment, further optimizing the usage effect.

[0017] 3. When this utility model is further combined with the above-mentioned multi-functional feeding device by setting the space adjustment component, the space adjustment component can indirectly realize quantitative feeding operation by repeatedly opening or closing the discharge port space at the bottom of the feeding hopper, thus avoiding the phenomenon of overload operation of the whole device.

[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] Example 1

[0027] Please see Figure 1-3 , Figure 5 A cottonseed dehulling device includes a dehulling box 1 and a support frame 2 installed on the outer surface of the dehulling box 1. The bottom of the dehulling box 1 is provided with a discharge port 3. The interior of the dehulling box 1 is fitted with two first dehulling tooth cylinders 4 and two second dehulling tooth cylinders 5 respectively. The two first dehulling tooth cylinders 4 and the two second dehulling tooth cylinders 5 are arranged in a one-to-one manner. Adjacent first dehulling tooth cylinders 4 and second dehulling tooth cylinders 5 form a meshing and dehulling space. The size of the two meshing and dehulling spaces decreases from top to bottom.

[0028] One end of each of the two first shelling cylinders 4 extends to the outer front end of the shelling box 1, and one end of each of the two second shelling cylinders 5 extends to the outer rear end of the shelling box 1. The front and rear ends of the shelling box 1 are respectively provided with a first meshing output component and a second meshing output component. The first meshing output component and the second meshing output component can respectively drive the output of the two first shelling cylinders 4 and the two second shelling cylinders 5, thereby enabling the adjacent first shelling cylinders 4 and the second shelling cylinders 5 to rotate relative to each other. The surfaces of the two first shelling cylinders 4 and the two second shelling cylinders 5 are provided with wear-resistant coatings, and the wear-resistant coatings can specifically be hard alloy coatings, thereby improving the wear resistance of the two first shelling cylinders 4 and the two second shelling cylinders 5.

[0029] The first meshing output assembly includes two first transmission gears 6, the output ends of which are respectively connected to one end of the corresponding two first shelling cylinders 4. A first fixed seat is installed between the housing surface of the two first transmission gears 6 and the front end surface of the shelling box 1. The second meshing output assembly includes two first servo motors 7, the output ends of which are respectively connected to one end of the corresponding two second shelling cylinders 5. A second fixed seat is installed between the housing surface of the two first servo motors 7 and the rear end surface of the shelling box 1. A clearance space is provided between the two first shelling cylinders 4 and between the two second shelling cylinders 5. A guide baffle 12 is installed in each of the two clearance spaces. One side of each guide baffle 12 is set to be inclined towards the discharge port 3. The two guide baffles 12 are used to assist in guiding the falling movement of the material.

[0030] In the specific implementation process:

[0031] Before the shelling process, the two first transmission gears 6 inside the first meshing output assembly and the two first servo motors 7 inside the second meshing output assembly are started respectively, and the first transmission gears 6 and the first servo motors 7 are made to rotate at different speeds. For example, the output speed of the first transmission gear 6 associated with the first shelling gear cylinder 4 is greater than the output speed of the first servo motor 7 associated with the second shelling gear cylinder 5. Then, the two first shelling gear cylinders 4 and the two second shelling gear cylinders 5 are aligned one by one and rotate relative to each other.

[0032] Next, the cottonseed to be processed is placed in the meshing and dehulling space closest to the top opening of the dehulling box 1. At this time, a set of opposing first dehulling tooth cylinders 4 and second dehulling tooth cylinders 5 will initially mesh and break the cottonseed. Since the rotation speed of the first dehulling tooth cylinder 4 is greater than that of the second dehulling tooth cylinder 5, in the specific dehulling process, the first dehulling tooth cylinder 4 will play the main shearing and dehulling role, while the second dehulling tooth cylinder 5 will play the secondary shearing and lifting role of the cottonseed, thereby fully improving the dehulling efficiency of the cottonseed.

[0033] The cottonseed raw material that has undergone preliminary dehulling will then flow further into the meshing and dehulling space closest to the bottom of the dehulling box 1. Similarly, at this time, the remaining set of opposing first dehulling tooth cylinders 4 and second dehulling tooth cylinders 5 will perform secondary meshing and dehulling on the incompletely dehulled cottonseed. Since the rotation speed of the first dehulling tooth cylinder 4 is greater than that of the second dehulling tooth cylinder 5, in the specific dehulling process, the first dehulling tooth cylinder 4 will play the main shearing and dehulling role, while the second dehulling tooth cylinder 5 will play the secondary shearing and lifting role of the cottonseed, thereby fully ensuring the quality of cottonseed dehulling.

[0034] Example 2

[0035] Please see Figure 1-3 , Figure 5-6The top inner side of the shelling box 1 is fitted with a feeding bin 8, and elastic limiting rods 9 are provided between one side of the middle of the feeding bin 8 and one side of the top of the shelling box 1, and between the other side of the middle of the feeding bin 8 and the other side of the top of the shelling box 1. A cam transmission assembly 10 is provided between the feeding bin 8 and the shelling box 1. The bottom of the shelling box 1 is provided with a discharge port that is aligned with the meshing and shelling space closest to the top port of the shelling box 1.

[0036] The elastic limiting rod 9 includes a T-shaped rod 91 and a buffer spring 92. The two ends of the T-shaped rod 91 are respectively snapped onto the corresponding side of the feeding bin 8 and fixedly connected to the top surface of the shelling box 1. The two ends of the buffer spring 92 are respectively fixedly connected to the surface of the corresponding side of the feeding bin 8 and the surface of the top of the shelling box 1. The elastic limiting rod 9 serves as a support condition, enabling the feeding bin 8 and the shelling box 1 to be used stably as a whole. The cam transmission assembly 10 includes a second servo motor 101 and a cam block body 102. The output end of the second servo motor 101 is connected to the cam block body 102 for transmission. The cam block body 102 can reciprocate to press the feeding bin 8 under the synchronous rotation output of the second servo motor 101, vibrating the feeding bin 8 to prevent blockage and improve the efficiency of use.

[0037] In the specific implementation process:

[0038] Considering the need for large-scale processing in the future, a certain amount of cottonseed can be placed inside the feeding bin 8. Then, the cottonseed inside the feeding bin 8 will be fed into the corresponding meshing and dehulling space in a horizontal arrangement through the discharge port at the bottom of the feeding bin 8, thereby providing favorable conditions for subsequent rapid meshing and dehulling and meeting the requirements for long-term uninterrupted feeding.

[0039] Considering that the feeding bin 8 may experience blockage during continuous material discharge, the second servo motor 101 inside the cam transmission assembly 10 can be periodically activated during the material feeding process of the feeding bin 8. This causes the output end of the second servo motor 101 to drive the cam block body 102 to reciprocate and impact the feeding bin 8, thereby causing the feeding bin 8 to oscillate back and forth under the limiting guidance of multiple elastic limit rods 9, achieving an automated blockage clearing effect.

[0040] Example 3

[0041] Please see Figure 4A space adjustment component 11 is provided inside the discharge port. The space adjustment component 11 includes an adjustment plate 111. The two ends of the adjustment plate 111 are movably connected to the front and rear end structures of the bottom of the feeding bin 8, and one end of the adjustment plate 111 passes through the outer front end of the feeding bin 8 and is connected to a second transmission gear 112. An electric push rod 114 is installed on the front surface of the feeding bin 8. The output end of the electric push rod 114 is connected to a straight tooth plate 113 that can be connected to the second transmission gear 112. Under the transmission output of the electric push rod 114 through the second transmission gear 112 and the straight tooth plate 113, the adjustment plate 111 can rotate to close or rotate to open the discharge port. The space adjustment component 11 is used to open or close the discharge port, thereby realizing a relatively quantitative discharge adjustment and further optimizing the overall device performance.

[0042] In the specific implementation process:

[0043] Considering the overload problem of the device during large-scale processing, the discharge from feeding hopper 8 can be adjusted to periodic quantitative output, with the following raw materials:

[0044] During the discharge process of the feeding bin 8, the electric push rod 114 is opened and closed repeatedly. The output end of the electric push rod 114 drives the straight tooth plate 113 to reciprocate and mesh with the second transmission gear 112. Then, the second transmission gear 112 drives the adjusting plate 111 to rotate synchronously, so that the adjusting plate 111 reciprocates to open or close the bottom discharge port space of the feeding bin 8. This allows the raw materials inside the feeding bin 8 to be periodically discharged into the corresponding meshing and deshelling space in a relatively quantitative manner, thereby providing favorable conditions for subsequent rapid meshing and deshelling and meeting the requirements of long-term uninterrupted material supply.
