Description

Technical Field

[0001] This utility model relates to the field of Trichosanthes kirilowii seed processing technology, specifically to a shelling device for processing Trichosanthes kirilowii seeds. Background Technology

[0002] In the research and development of mechanized shelling equipment for Trichosanthes kirilowii seeds, the shelling mechanism, as the core execution component that directly acts on the seeds, directly determines the efficiency of the shelling process and the quality of the finished product due to its feeding positioning accuracy, the rationality of the extrusion transmission, and the initial separation effect of the shell and kernel. On the one hand, the transmission components of existing shelling mechanisms are mostly "grooveless smooth structures", with a small contact area with the seeds and insufficient friction. The seeds are prone to stalling due to roller slippage during the extrusion process, resulting in low single-channel feeding efficiency. On the other hand, most equipment adopts an extrusion mode of "single transmission column + fixed baffle" or double transmission columns but rotating in the same direction, which cannot form a stable opposing extrusion force. When rotating in the same direction, the seeds are easily driven by the transmission column to move in the same direction, and the extrusion time is too short, resulting in incomplete shell breaking. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a shelling device for processing Trichosanthes kirilowii seeds, which has the advantages of stable and uniform extrusion pressure, improving shelling quality, and solving the problem of incomplete shell breaking.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A shelling device for processing Trichosanthes kirilowii seeds includes a body serving as the carrier of the entire device. An outer frame is fixedly connected to the body, and multiple hoppers are provided inside the outer frame. The body is equipped with a shelling mechanism that removes the outer shell of Trichosanthes kirilowii seeds by extrusion. The shelling mechanism includes two drive columns rotatably mounted inside the body, which rotate in opposite directions. Multiple drive grooves are formed on the drive columns, and each drive groove corresponds to the discharge port of a multiple hopper. Multiple limiting discs are provided on both sides of the drive grooves, and the multiple limiting discs are arranged in a ring and fixedly connected to the drive columns. A shell is fixedly connected inside the body, and multiple nozzles for blowing away the outer shell are provided on one side of the shell.

[0005] Preferably, a filter plate is slidably connected inside the housing, one end of the filter plate extends sequentially to the outside of the housing and the machine body through a sliding groove, support blocks are fixedly connected to the four corners inside the housing, springs are fixedly connected between the support blocks and the filter plate, and a drive shaft is rotatably mounted on the housing, with a cam fitted on the drive shaft for pushing the filter plate to move upward.

[0006] Preferably, a connecting shaft is fixedly connected to the middle of the transmission column, and a spur gear for meshing transmission is fixedly connected to the end of the connecting shaft. The connecting shaft is rotatably connected to the machine body through a bearing. A motor for driving one of the connecting shafts is fixedly mounted on the machine body, and a belt assembly is provided between the transmission shaft and one of the connecting shafts.

[0007] Preferably, a fan is provided on one side of the machine body, the air outlet pipe of the fan is connected to a guide pipe, and multiple nozzles are connected and installed on the guide pipe.

[0010] By means of the above technical solution, this utility model provides a shelling device for processing Trichosanthes kirilowii seeds, which has at least the following beneficial effects: 1. This shelling device for processing Trichosanthes kirilowii seeds, by setting a shelling mechanism, can not only accurately confine the Trichosanthes kirilowii seeds in the transmission groove to prevent them from shifting or slipping during the conveying and extrusion process, but also realize the synchronous rotation of the two transmission columns in opposite directions to form a stable and uniform extrusion force, thereby achieving continuous shelling operation and effectively reducing the unshelled rate and seed breakage rate caused by material misalignment in traditional equipment.

[0014] 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.

[0015] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a shelling device for processing Trichosanthes kirilowii seeds.

[0016] Example 1: Combination Figures 1-4 As shown, the present invention provides a shelling device for processing Trichosanthes kirilowii seeds, including a body 100 as the carrier of the entire device, an outer frame 102 fixedly connected to the body 100, a plurality of hoppers 103 provided inside the outer frame 102, and a shelling mechanism 200 provided on the body 100 for removing the outer shell of Trichosanthes kirilowii seeds by extrusion, so that the shelling process can be carried out continuously. Compared with manual shelling or intermittent equipment, it can significantly improve the shelling efficiency and meet the needs of large-scale processing. The shelling mechanism 200 includes two drive columns 201 rotatably mounted inside the machine body 100. The two drive columns 201 rotate in opposite directions. Multiple drive grooves 202 are formed on each drive column 201, corresponding to the discharge ports of multiple hoppers 103. Multiple limiting discs 203 are provided on both sides of each drive groove 202, arranged in a ring and fixed to the drive column 201. First, the seeds of the trichosanthes fruit are placed into the hoppers 103 inside the outer frame 102. Then, the seeds fall from the discharge ports of the hoppers 103 into the drive grooves 202 on the two drive columns 201. The two drive columns 201 rotate towards the center, squeezing the seeds. The seeds of Trichosanthes kirilowii are shelled, and the separated kernels and shells fall to the bottom. A housing 207 is fixed inside the machine body 100. Multiple nozzles 216 are provided on one side of the housing 207 to blow away the shells. The nozzles 216 spray gas to blow the lighter shells to one side, while the heavier kernels fall into the housing 207. This separates the shells from the kernels and accurately confines the seeds within the transmission groove 202, preventing them from shifting or slipping during conveying and compression. This solves the problems of "unshelled" (seeds not entering the compression zone) or "crushed kernels" (seeds being over-compressed after shifting) caused by material misalignment in traditional equipment, thus improving the stability of shelling.

[0017] Specifically, a filter plate 208 is slidably connected inside the housing 207. One end of the filter plate 208 extends sequentially to the outside of the housing 207 and the machine body 100 via a sliding groove. Support blocks 212 are fixedly connected to the four corners inside the housing 207. Springs 213 are fixedly connected between the support blocks 212 and the filter plate 208. A drive shaft 210 is rotatably mounted on the housing 207. A cam 211 is fitted on the drive shaft 210 to push the filter plate 208 upward. The seeds of Trichosanthes kirilowii fall onto the filter plate 208, and incomplete or small seeds pass through. As the filter holes descend, the drive shaft 210 rotates, causing the cam 211 to rotate. The cam 211 rotates upward and contacts the filter plate 208, causing it to rise. Subsequently, the cam 211 disengages from the filter plate 208. Due to the action of the spring 213, the filter plate 208 vibrates. This not only prevents the kernels of Trichosanthes kirilowii from getting stuck in the filter holes (solving the problem of "material accumulation and clogging, and screening stagnation" in traditional fixed filter plates 208), but also speeds up the conveying speed of qualified kernels to the discharge port of the shell 207. Compared with static screening, efficiency is improved and processing downtime is reduced.

[0018] Furthermore, a fan 214 is provided on one side of the machine body 100. The air outlet pipe of the fan 214 is connected to a guide pipe 215. Multiple nozzles 216 are connected and installed on the guide pipe 215. When the fan 214 is started, the outside gas is sprayed out from the nozzles 216 through the air outlet pipe and the guide pipe 215 in sequence, so as to separate the kernel and shell of the Trichosanthes kirilowii seed. The separation of kernel and shell is achieved through physical properties. Compared with manual sorting, it can improve efficiency and avoid omissions during manual sorting, and reduce the rate of shells in the kernel.

[0019] A guide plate 209 is installed at an angle on the side of the housing 207 away from the nozzle 216. Material boxes 101 are respectively provided at the lower angle of the guide plate 209, the outlet of the housing 207, and the lower angle of the filter plate 208.

[0020] As can be seen from the embodiment, the two transmission columns 201 rotate in opposite directions to form opposing extrusion, which can continuously receive the Trichosanthes kirilowii seeds conveyed by the hopper 103. Compared with manual or intermittent shelling equipment, it can achieve "continuous feeding and continuous shelling", which is suitable for batch processing needs. At the same time, the design of the transmission groove 202 can fit the particle shape of Trichosanthes kirilowii seeds, so that the extrusion pressure is applied to the shell more evenly, reducing the damage to the kernel caused by excessive local stress.

[0021] Example 2: Combination Figure 2 and Figure 3As shown, based on Embodiment 1, a connecting shaft 205 is fixedly connected to the middle of the transmission column 201, and a meshing spur gear 206 is fixedly connected to the end of the connecting shaft 205. The connecting shaft 205 is rotatably connected to the machine body 100 through a bearing. A motor 204 for driving one of the connecting shafts 205 is fixedly mounted on the machine body 100. A belt assembly is provided between the transmission shaft 210 and one of the connecting shafts 205. When the motor 204 starts, it drives one of the connecting shafts 205 to rotate. The connecting shaft 205 drives the other connecting shaft 205 to rotate through the spur gear 206, thereby causing the two transmission columns 201 to rotate towards the middle to achieve the shell removal operation. At the same time, the connecting shaft 205 drives the transmission shaft 210 to rotate through the belt assembly. The transmission shaft 210 drives the cam 211 to rotate, thereby achieving the vibration operation of the filter plate 208. Thus, multiple operations can be achieved using a single power source, which helps to reduce the cost of the equipment.

[0022] Specifically, the belt assembly includes pulleys mounted on the drive shaft 210 and one of the connecting shafts 205. The pulleys are connected by belt drive, which can ensure the stable vibration frequency of the filter plate 208, avoid uneven screening caused by sudden changes in vibration speed, and balance the comfort of the processing environment with the screening accuracy.

[0023] As can be seen from the above embodiments: Subsequently, the motor 204 fixed on the machine body 100 is started. The motor 204 drives one of the connecting shafts 205 to rotate. The connecting shaft 205 meshes with the other connecting shaft 205 through a spur gear 206 fixed at its end, driving the two transmission columns 201 to rotate towards the middle. The extrusion action is used to remove the shells from the Trichosanthes kirilowii seeds in the transmission groove 202. At the same time, the connecting shaft 205 drives the transmission shaft 210 on the housing 207 to rotate through the belt assembly. The cam 211 on the transmission shaft 210 rotates with it and periodically pushes the filter plate 208 slidably connected in the housing 207 to move upward. When the cam 211 disengages from the filter plate 208, the filter plate 208 is reset under the action of the spring 213 fixed between the four corner support blocks 212 and the filter plate 208 in the housing 207, forming continuous vibration. During the falling process of the mixed Trichosanthes kirilowii seeds and shells after shelling, the machine body is started. The fan 214 on one side of 100 delivers outside air through the outlet pipe to the guide pipe 215, and then sprays air onto one side of the housing 207 through multiple nozzles 216 connected to the guide pipe 215. The lighter outer shell is blown by the airflow onto the guide plate 209 installed at an angle on the side of the housing 207 away from the nozzles 216, and then slides down the guide plate 209 into the material box 101 below it for collection; the heavier Trichosanthes kirilowii seeds fall into the material box 101. Inside the housing 207, under the vibration of the filter plate 208, incomplete and small-sized unqualified Trichosanthes kirilowii seeds pass through the filter holes of the filter plate 208 and fall into the material box 101 diagonally below the filter plate 208. Qualified Trichosanthes kirilowii seeds are discharged from the outlet of the housing 207 with the vibration of the filter plate 208 and fall into the corresponding material box 101 below the outlet, thus completing the entire process of shelling, separating the shell and kernel of Trichosanthes kirilowii seeds, and collecting qualified Trichosanthes kirilowii seeds.
