Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a negative pressure feeding device for rapeseed. Background Technology

[0002] Rapeseed is a common crop seed, mainly used for extracting edible oil, and also has some applications in traditional medicine and health care. After harvesting, rapeseed needs to undergo washing and oil extraction processes, so it usually needs to be transported to other places for processing. Currently, this is mainly done by loading rapeseed onto transport vehicles and then transporting it to the hopper at the processing location.

[0003] After the rapeseed is transported to the processing location, it needs to be unloaded. The transport vehicle can unload the rapeseed by tilting the cargo box, but the hopper is usually located at a high position, making it difficult for the cargo box to pour the rapeseed directly into the hopper. Subsequently, the rapeseed needs to be manually fed into the hopper, resulting in a slow loading speed. Utility Model Content

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] according to Figure 1-3 This utility model provides a negative pressure feeding device for rapeseed, including: a storage bin 1, a conveying pipe 2, a negative pressure pump 3, a support 4, a dust removal device 5, and a dust removal pump 6.

[0018] Storage silo 1 is located on the ground; storage silo 1 is connected to negative pressure pump 3. Negative pressure pump 3 is connected to conveying pipe 2. The side of conveying pipe 2 furthest from the ground is mounted on support 4. Conveying pipe 2 is connected to the side of support 4 furthest from the ground.

[0019] When rapeseed needs to be fed, since the storage silo 1 is located on the ground at a low height, the cargo box can be tilted to pour the material into the storage silo 1 first. Then, the negative pressure pump 3 is started to suck the material from the storage silo 1 and send it to the conveying pipe 2. The material is transported to a higher position in the conveying pipe 2. By setting the outlet of the conveying pipe 2 at the hopper to be fed, the material can be sent into the hopper. By using negative pressure feeding, the material can be quickly sent into the hopper, ensuring the rapeseed feeding speed.

[0020] The storage bin 1 includes: a base plate 11, a feeding plate 13, and a feeding pipe 14. One end of the feeding pipe 14 is connected to the negative pressure pump 3, and the other end is connected to the feeding plate 13. The base plate 11 is connected to the feeding pipe 14. The base plate 11 is inclined toward the feeding pipe 14. The storage bin 1 also includes: side plates 12. The side plates 12 are disposed on both sides of the base plate 11. The side plates 12 are connected to the feeding pipe 14. The side plates 12 are inclined toward the feeding pipe 14. The side of the feeding pipe 14 closest to the feeding plate 13 is semi-circular. The feeding plate 13 has a semi-circular feeding port corresponding to the feeding pipe 14.

[0021] The bottom plate 11 of the storage bin 1 of this utility model is inclined towards the feeding pipe 14. When the rapeseed is unloaded into the storage bin 1, it will reach the feeding pipe 14 along the inclined surface. If the storage bin 1 has a horizontal bottom, some materials in the storage bin 1 that are far from the feeding pipe 14 may be difficult to be sucked in by the negative pressure pump 3, and these materials need to be moved to the feeding pipe 14 manually. However, the inclined bottom plate 11 allows the materials to move to the feeding pipe 14 by their own gravity, making the rapeseed feeding process more convenient and faster. When the material moves along the base plate 11 towards the feeding pipe 14, some material may not move directly to the feeding pipe 14, but instead move to the sides of the feeding pipe 14, a position farther away from the feeding pipe 14. This would make it difficult for the negative pressure pump 3 to suck it in. This invention has a side plate 12 inclined towards the feeding pipe 14, so that when the material moves towards the feeding pipe 14, it will be resisted by the inclined surface of the side plate 12 and automatically converge to a position close to the feeding pipe 14, making it easier for the negative pressure pump 3 to suck it in. The feeding pipe 14 of this invention is connected to the side of the storage bin 1 near the negative pressure pump 3. Compared to setting it on the side of the storage bin 1 closer to the ground, this allows the height of the storage bin 1 to be set lower, making it easier to unload the rapeseed. The connection between the storage bin 1 and the feeding pipe 14 is a semi-circular opening. The bottom of the circular opening is narrower, which may make it difficult for some material to enter the feeding pipe 14. The bottom of the semi-circular opening is wider, making it easier for the material to enter the feeding pipe 14.

[0022] The conveying pipe 2 includes a discharge pipe 21. The discharge pipe 21 is mounted on the support 4. The dust removal device 5 is located inside the discharge pipe 21 on the side away from the support 4. The dust removal pump 6 is connected to the dust removal device 5. The dust removal device 5 includes a filter screen 51 and an output pipe 52. The filter screen 51 is located on the side of the dust removal device 5 closest to the storage silo 1. The output pipe 52 is located on the side of the dust removal device 5 away from the storage silo 1.

[0023] The materials are exposed to an open environment for extended periods during transportation by transport vehicles and placement in storage silos 1. These machines also contain impurities, making the rapeseed easily contaminated with dust, which can affect subsequent oil extraction and grinding processes. This invention includes a dust removal device 5 connected to a dust removal pump 6. When the material enters the conveying pipe 2 and reaches the discharge pipe 21, it is drawn in by the suction of the dust removal pump 6, causing dust to be sucked into the dust removal device 5 and discharged through the output pipe 52. The dust removal device 5 is equipped with a filter screen at the dust inlet end, allowing smaller dust particles to pass through while preventing larger rapeseed particles from entering. Since the dust removal device 5 is located inside the discharge pipe 21 on the side away from the support 4, the suction force of the dust removal pump 6 can be kept within a certain range, allowing lighter dust particles to be sucked in by the dust removal pump, while the medium-sized rapeseed particles will fall down by gravity and continue to be transported into the hopper through the discharge pipe 21. Through the above structure, the dust removal device will only suck up dust, with less impact on the rapeseed particles, so as to separate the rapeseed particles from the dust.

[0024] Working principle and usage process of this utility model:

[0025] In use, the material is unloaded into the storage bin 1. The material moves towards the feeding pipe 14 by gravity on the bottom plate 11 and moves closer to the feeding pipe 14 along the side plate 12. At the same time, the negative pressure pump 3 and the dust removal pump 6 are turned on, so that the material is sucked into the feeding pipe 14 when it reaches the vicinity of the feeding plate 13. Then, it enters the conveying pipe 2 through the negative pressure pump 3 and moves towards the discharge pipe 21. When the material moves to the discharge pipe 21, the dust on the material is sucked into the dust removal device 5 through the filter screen 51 and discharged through the output pipe 52. The rapeseed continues to be conveyed in the discharge pipe 21 and finally enters the hopper, completing the negative pressure material collection.

[0026] In summary, this utility model, by setting up a storage bin on the ground and also equipped with a negative pressure pump, allows materials to be directly unloaded into the storage bin and transported by the negative pressure pump, making rapeseed loading convenient and fast and ensuring the loading speed of rapeseed.
