Description

Technical Field

[0001] This utility model belongs to the field of tung oil seed processing technology, specifically relating to a crushing and screening machine for tung oil seed processing. Background Technology

[0002] Tung oil is an excellent drying vegetable oil with properties such as fast drying, light weight, good gloss, strong adhesion, heat resistance, acid and alkali resistance, corrosion resistance, rust prevention, and non-conductivity. It has a wide range of uses. It is the main raw material for manufacturing paints and inks, and is widely used as a waterproof, anti-corrosion, and rust-preventive coating for construction, machinery, weapons, vehicles, ships, fishing gear, and electrical appliances. It can also be used to make oilcloth, oil paper, soap, pesticides, and pharmaceutical emetics and insecticides. To obtain tung oil, the tung oil seeds must first be crushed, which requires a crushing device.

[0003] Patent application number 201821079859.6 discloses a tung oil seed kernel crushing device for tung oil processing, including an operating table. The upper end of the operating table is provided with a conical collection trough and an annular groove. The collection trough is located at the center of the upper end of the operating table. The groove overlaps with the axis of the collection trough. A discharge hole is provided at the center of the bottom of the collection trough. An annular rotating cylinder is provided in the groove. The upper end of the rotating cylinder passes through the groove opening and extends outward. The rotating cylinder is rotatably connected to the bottom of the groove. An annular transmission gear ring is fixed on the inner cylinder wall near the bottom of the rotating cylinder. Several evenly distributed first crushing teeth are fixed on the inner cylinder wall of the rotating cylinder.

[0004] The aforementioned tung oil processing tung oil seed kernel crushing device uses interlocking crushing teeth to crush tung oil seed kernels. However, during the crushing process, different tung oil seed kernels will be affected by gravity and pass downward through the crushing mechanism, resulting in inconsistent particle sizes after crushing. Oversized tung oil seed kernels will not be fully pressed, leading to a low oil yield. Utility Model Content

[0005] (1) Technical problems to be solved In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a crushing and screening machine for tung oil seed processing. This crushing and screening machine for tung oil seed processing aims to solve the technical problem that the crushed tung oil seed kernels have inconsistent particle sizes under the existing technology, and that excessively large tung oil seed kernels will not be fully pressed, resulting in low oil yield.

[0006] (2) Technical solution To solve the above-mentioned technical problems, this utility model provides a crushing and screening machine for tung oil seed processing, including a crushing and screening cylinder and a crushing seat fixed to the top of the inner wall of the crushing and screening cylinder. The crushing and screening cylinder is rotatably arranged with crushed blocks located above the crushing seat, and the outer wall of the crushing and screening cylinder is respectively equipped with a primary discharge channel and a secondary discharge channel. The crushing and screening cylinder is embedded with a filter plate and a guide plate corresponding to the primary discharge channel and the secondary discharge channel, respectively. The filter plate is equipped with a vibration mechanism inside.

[0007] When using this technical solution, by setting up corresponding crushing blocks and crushing seats, the crushing blocks, when rotating, and the densely packed crushing teeth on the crushing seats can fully crush the tung oil seed kernels. Simultaneously, the crushed tung oil seed kernels fall onto the surface of the filter plate. Larger tung oil seed kernels are discharged from the primary discharge channel along the inside and outside of the filter plate for accurate secondary crushing, while smaller tung oil seed kernels fall into the guide plate and are discharged from the secondary discharge channel for storage. This facilitates the screening of the crushed tung oil seed kernels and avoids the mixing of large and small particles, which would result in a low oil yield from the larger particles. By fixing a convex plate on the drive shaft, the filter plate is affected by its own weight and the spring compression force during use. The convex parts at both ends are located at the bottom of the groove. When the drive shaft drives the crushed block to rotate, the convex plate and the metal convex ball on the filter plate come into contact and squeeze each other once for each rotation. During the process of the two metal convex balls squeezing each other, the filter plate is driven to move upward. When the two convex balls separate, the self-weight and the spring compression force cause the filter plate to move downward. As a result, the filter plate vibrates up and down during the rotation of the crushed block, which reduces the clogging of tung oil seed kernels on the surface of the filter plate.

[0008] Preferably, the bottom end of the crushing and screening cylinder is provided with an installation groove, in which a motor is embedded and fixed. The bottom end of the crushed block is fixed with a drive shaft, and the bottom end of the drive shaft is rotatably inserted into the crushing and screening cylinder through a bearing. The drive shaft is fixed to the motor shaft.

[0009] Furthermore, the inner wall of the crushing and screening cylinder is fixed with mounting rods in a ring array at the top end, and the top end of the crushed block is fixed with a rotating shaft that is rotatably inserted between multiple mounting rods. The end of the crushed block that is close to the crushing seat is fixed with crushing teeth in a ring array, wherein the crushing teeth on the crushed block and the crushing seat are arranged alternately.

[0010] Furthermore, the primary discharge channel is located above the secondary discharge channel, and both the primary and secondary discharge channels are symmetrically arranged in two sets.

[0011] Furthermore, both the filter plate and the guide plate are fixed with a ring-shaped baffle plate at their top ends, and both baffle plates are sleeved on the drive shaft.

[0012] Furthermore, the vibration mechanism includes a convex plate fixed on the drive shaft and metal convex balls fixed on the convex plate and the filter screen respectively, with the convex plate and the metal convex balls on the filter screen being arranged alternately.

[0013] Furthermore, grooves are provided on both sides of the inner wall of the crushing and screening cylinder, and protrusions that slide into the grooves are provided at both ends of the filter plate. Rods that slide into the protrusions at both ends of the filter plate are fixed in the grooves, and springs are sleeved on the top of the rods.

[0014] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features corresponding crushing blocks and crushing seats. When the crushing blocks rotate, their interlaced and densely packed crushing teeth on the crushing seats thoroughly crush the tung oil seed kernels. Simultaneously, the crushed kernels fall onto the surface of the filter plate. Larger tung oil seed kernels are discharged from the primary discharge channel along the inside and outside of the filter plate for accurate secondary crushing, while smaller kernels fall into the guide plate and are discharged from the secondary discharge channel for storage. This facilitates the screening of the crushed kernels and avoids the mixing of large and small particles, which can lead to low oil yield from larger kernels. A convex plate is fixed on the drive shaft. When the filter plate is in use, its two protrusions are located at the bottom of the groove due to its own weight and the spring compression force. When the drive shaft drives the crushed block to rotate, the convex plate and the metal convex ball on the filter plate come into contact and squeeze each other once for each rotation. During the process of the two metal convex balls squeezing each other, the filter plate is driven to move upward. When the two convex balls separate, the self-weight and the spring compression force cause the filter plate to move downward. As a result, the filter plate vibrates up and down during the rotation of the crushed block, which reduces the clogging of tung oil seed kernels on the surface of the filter plate.

[0018] 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.

[0019] This specific embodiment is a crushing and screening machine for tung oil seed processing, and its structural schematic diagram is shown below. Figure 1 and Figure 2 As shown, the device includes a crushing and screening cylinder 1 and a crushing seat 11 fixed to the top of the inner wall of the crushing and screening cylinder 1. A crushing block 5 is rotatably disposed in the crushing and screening cylinder 1 above the crushing seat 11. A primary discharge channel 2 and a secondary discharge channel 4 are respectively installed on the outer wall of the crushing and screening cylinder 1. A filter plate 10 and a guide plate 9 corresponding to the primary discharge channel 2 and the secondary discharge channel 4 are embedded in the crushing and screening cylinder 1. A vibration mechanism is provided inside the filter plate 10.

[0020] The bottom end of the crushing and screening cylinder 1 is provided with an installation groove 3, in which a motor 8 is embedded and fixed. The bottom end of the crushed block 5 is fixed with a drive shaft 7, which is rotatably inserted into the crushing and screening cylinder 1 through a bearing. The drive shaft 7 is fixed to the shaft of the motor 8. The top of the inner wall of the crushing and screening cylinder 1 is fixed with mounting rods 12 in a ring array. The top of the crushed block 5 is fixed with a rotating shaft 13 that is rotatably inserted between multiple mounting rods 12. The ends of the crushed block 5 and the crushing seat 11 are both fixed with crushing teeth 6 in a ring array. The crushing teeth 6 on the crushed block 5 and the crushing seat 11 are staggered. The multiple mounting rods 12 are fixed together. There is a circular plate, and the rotating shaft 13 is inserted into the circular plate through the bearing. The primary discharge channel is set above the secondary discharge channel, and there are two sets of primary discharge channels 2 and secondary discharge channels 4 symmetrically arranged. When the crushing block 5 rotates, its interlaced and dense crushing teeth 6 on the crushing seat 11 can fully crush the tung oil seed kernels. At the same time, the crushed tung oil seed kernels fall onto the surface of the filter plate 10. Large tung oil seeds are discharged from the primary discharge channel 2 along the inside and outside of the filter plate 10 for accurate secondary crushing and processing. Small tung oil seed kernels fall into the guide plate 9 and are discharged from the secondary discharge channel 4 for storage, which facilitates the screening of the crushed tung oil seed kernels.

[0021] like Figure 3 and Figure 4 As shown, both the filter plate 10 and the guide plate 9 have annular baffle plates 16 fixed to their top ends. Both baffle plates 16 are sleeved on the drive shaft 7. The baffles can block the crushed particles. A cavity for accommodating the rotation of the drive shaft 7 is provided at the center of both the filter plate 10 and the guide plate 9. The filter plate 10 is slidably disposed in the crushing and screening cylinder 1. The guide plate 9 is fixed to the inner wall of the crushing and screening cylinder 1. The vibration mechanism includes a convex plate 14 fixed to the drive shaft 7 and metal convex balls fixed to the convex plate 14 and the filter screen respectively. The convex plate 14 and the metal convex balls on the filter screen are staggered. Grooves 19 are provided on both sides of the inner wall of the crushing and screening cylinder 1. Both ends are provided with protrusions that slide into the grooves 19. Rods 17 are fixed in the grooves 19 and slide into the protrusions at both ends of the filter plate 10. A spring 18 is sleeved on the top of the rod 17. When the drive shaft 7 drives the crushed block 5 to rotate, the protruding plate 14 contacts and squeezes the metal protruding ball on the filter plate 10 once for each rotation. During the squeezing process of the two metal protruding balls, the filter plate 10 is driven to move upward. When the two protruding balls separate, their own weight and the squeezing force of the spring 18 cause the filter plate 10 to move downward. This causes the filter plate 10 to vibrate up and down during the rotation of the crushed block 5, reducing the clogging of tung oil seed kernels on the surface of the filter plate 10.

[0022] Working principle: When using the device of this technical solution, the starting motor 8 drives the drive shaft 7 and the crushing block 5 to rotate. Tung oil seed kernels are fed from the top of the crushing and screening cylinder 1 and fall down along the inclined top of the crushing block 5. When the crushing block 5 rotates, its interlaced and densely packed crushing teeth 6 on the crushing seat 11 can fully crush the tung oil seed kernels. At the same time, the crushed tung oil seed kernels fall onto the surface of the filter plate 10. Large tung oil seed kernels are discharged from the primary discharge channel 2 along the inside and outside of the filter plate 10 for accurate secondary crushing and processing. Small tung oil seed kernels fall into the guide plate 9 and are discharged from the secondary discharge channel 4 for storage. When the filter plate 10 is in use, it is affected by its own weight and the squeezing force of the spring 18. The protrusions at both ends of the filter plate 10 are located at the bottom of the groove 19. When the drive shaft 7 drives the crushed block 5 to rotate, the protruding plate 14 and the metal protruding ball on the filter plate 10 come into contact and squeeze each other once for each rotation. During the process of the two metal protruding balls squeezing each other, the filter plate 10 is driven to move upward. When the two protruding balls separate, the self-weight and the squeezing force of the spring 18 cause the filter plate 10 to move downward. As a result, the filter plate 10 vibrates up and down during the rotation of the crushed block 5, which reduces the clogging of tung oil seed kernels on the surface of the filter plate 10.

[0023] All technical features in this embodiment can be freely combined according to actual needs.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
