Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal device technology, and more specifically, to a dust removal device for a wheat seed selection vehicle. Background Technology
[0002] Vibrating screens work by using reciprocating rotary vibrations generated by vibrators. When screening crop seeds, such as corn and wheat, the vibrations separate the different particle sizes of the corn and wheat seeds to facilitate breeding. However, the process of screening seeds generates a lot of dust, which affects the working environment of the staff.
[0003] Patent authorization number CN221086268U discloses a crop seed selection device, including a screening cylinder. A horizontal plate is fixedly connected to the upper end of the screening cylinder, and a sieving cylinder is provided at the bottom end of the horizontal plate. A vertical rod is fixedly connected to the bottom inside the sieving cylinder, and a spiral plate located inside the sieving cylinder is fixedly connected to the outer wall of the vertical rod. Multiple evenly distributed sieving holes are opened through the outer wall of the sieving cylinder. Because there is a spiral plate on the outer wall of the vertical rod, under the action of centrifugal force, corn and wheat seeds rotate along the inner wall of the sieving cylinder while moving downward. The multiple sieving holes through the outer wall of the sieving cylinder separate corn or wheat seeds of suitable size, while corn or wheat seeds that are too large and impurities such as straw are collected in the sieving cylinder, thereby achieving the purpose of facilitating the screening of corn, wheat and other crop seeds and facilitating the removal of straw from crop seeds.
[0004] However, the patent authorization number CN221086268U can only collect large corn or wheat seeds and straw and other impurities in the screening cylinder during the seed screening process, but it cannot deal with the dust that is raised, causing dust to rise around the device and affecting the working environment of the staff. Therefore, we have proposed a dust removal device for a wheat seed selection vehicle to solve the above-mentioned problems. Utility Model Content
[0005] 1. Technical problems to be solved
[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a dust removal device for a wheat seed selection vehicle, which removes dust from wheat seeds during the selection process to ensure the working environment of the staff.
[0007] 2. Technical Solution
[0008] To solve the above problems, the present invention adopts the following technical solution.
[0009] A dust removal device for a wheat seed selection vehicle includes a screening cylinder, a support plate fixedly connected to the top of the screening cylinder, a material pipe installed on the side wall of the support plate, and a feeding hopper fixedly connected to the end of the material pipe. A fan is installed at the top of the support plate.
[0010] The fan is equipped with a conical air guide shroud at the air outlet end, and an air duct check valve is installed at the air outlet end of the conical air guide shroud.
[0011] A collection bucket is provided on one side of the screening cylinder. A bucket cover is detachably connected to the top of the collection bucket. A connector is integrally formed on the bucket cover, and a corrugated hose is installed between the connector and the air duct check valve.
[0012] One side of the connector is fixedly connected to an externally threaded vent pipe that passes through the bucket lid. An internally threaded sleeve is screwed onto the externally threaded vent pipe, and the top of the internally threaded sleeve is filled with filter cotton.
[0013] Furthermore, a baffle with an arc-shaped structure is fixedly connected to the top end of the material tube.
[0014] Furthermore, the lower surface edge of the bucket lid is integrally formed with a boss in a ring structure.
[0015] Furthermore, the outer wall of the protrusion is inlaid with a sealing ring that fits against the inner wall of the top opening of the collection bucket.
[0016] Furthermore, the top end of the internally threaded sleeve is integrally formed with a limiting part having an annular structure.
[0017] Furthermore, an annular drip tube located below the protrusion is fixedly connected to the inner wall of the top opening of the collection bucket.
[0018] Furthermore, a water injection pipe is fixedly connected to the side wall of the collection bucket and is in communication with the annular drip pipe.
[0019] 3. Beneficial effects
[0020] Compared with existing technologies, the advantages of this utility model are:
[0021] (1) In this scheme, wheat seeds are fed into the screening cylinder through the feed pipe using a feeding hopper for selection. At the same time, the blower is turned on to suck up the dust that is raised during the selection of wheat seeds. The dust is then transported to the collection bucket through the corrugated hose via a conical guide hood. During this process, the dust is prevented from flowing backward through the air duct check valve. Excess air in the collection bucket is discharged through the external threaded air outlet pipe. The dust in the discharged gas is intercepted by the filter cotton set inside the internal threaded sleeve to prevent dust from overflowing and to ensure the air pressure balance inside the collection bucket. By removing dust from the wheat seeds during the selection process, the working environment of the staff is guaranteed.
[0022] (2) In this scheme, during the process of collecting dust in the collection bucket, water is injected into the annular drip pipe by an external water pump connected to the water injection pipe, and the water drips from the annular drip pipe to the inside of the collection bucket. This can effectively prevent the dust from being stirred up again and is conducive to the treatment of the dust inside the collection bucket. Attached Figure Description

Detailed Implementation
[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0031] Example:
[0032] Please see Figure 1-5 A dust removal device for a wheat seed selection vehicle includes a screening cylinder 1, a support plate 2 fixedly connected to the top of the screening cylinder 1, a material pipe 3 installed on the side wall of the support plate 2, and a feeding hopper 4 fixedly connected to the end of the material pipe 3. A fan 6 is installed at the top of the support plate 2.
[0033] A conical guide shroud 7 is installed at the air outlet end of the fan 6, and a duct check valve 8 is installed at the air outlet end of the conical guide shroud 7.
[0034] A collection bucket 9 is provided on one side of the screening cylinder 1. A bucket cover 10 is detachably connected to the top of the collection bucket 9. A connector 11 is integrally formed on the bucket cover 10, and a corrugated hose 12 is installed between the connector 11 and the air duct check valve 8.
[0035] One side of the connector 11 is fixedly connected to an external threaded air outlet pipe 15 that passes through the barrel cover 10. An internal threaded sleeve 16 is screwed onto the external threaded air outlet pipe 15. The top of the internal threaded sleeve 16 is filled with filter cotton 17.
[0036] It should be noted that when the dust removal device of this wheat seed selection vehicle is in use, wheat seeds are added to the screening cylinder 1 through the feed pipe 3 via the feeding hopper 4 for selection. At the same time, the fan 6 is turned on to suck up the dust that is raised during the selection process and transports the dust to the collection bucket 9 through the corrugated hose 12 via the conical guide hood 7. During this process, the backflow preventer valve 8 prevents the dust from flowing backward. Excess air in the collection bucket 9 is discharged through the external threaded air outlet pipe 15 and the dust in the discharged air is intercepted by the filter cotton 17 located inside the internal threaded sleeve 16. This prevents the dust from overflowing and ensures the air pressure balance inside the collection bucket 9. By removing dust from the wheat seeds during the selection process, the working environment of the staff is guaranteed.
[0037] like Figure 2 As shown, a baffle 5 with an arc-shaped structure is fixedly connected to the top end of the material pipe 3;
[0038] It should be noted that by setting a baffle 5 at the end of the feed pipe 3, the wheat seeds discharged from the end of the feed pipe 3 can be effectively prevented from being sucked up by the fan 6.
[0039] like Figure 5 As shown, the lower surface edge of the bucket lid 10 is integrally formed with a ring-shaped protrusion 13, and the outer wall of the protrusion 13 is inlaid with a sealing ring 14 that fits against the inner wall of the top opening of the collection bucket 9.
[0040] It should be noted that the sealing ring 14 provided on the boss 13 fills the gap between the barrel lid 10 and the collection barrel 9, thereby preventing dust from overflowing.
[0041] like Figure 5 As shown, the top end of the internally threaded sleeve 16 is integrally formed with a limiting part in the form of a ring structure;
[0042] It should be noted that by using the limiting part to limit the filter cotton 17, the filter cotton 17 is prevented from being squeezed out when installing the internal threaded sleeve 16.
[0043] like Figure 4 As shown, an annular dripping pipe 19 located below the boss 13 is fixedly connected to the inner wall of the top opening of the collection bucket 9, and a water injection pipe 18 connected to the annular dripping pipe 19 is fixedly connected to the side wall of the collection bucket 9.
[0044] It should be noted that during the dust collection process in the collection bucket 9, water is injected into the annular drip pipe 19 through the water injection pipe 18 connected to an external water pump, and the water drips from the annular drip pipe 19 onto the inside of the collection bucket 9. This effectively prevents the dust from being stirred up again and facilitates the treatment of the dust inside the collection bucket 9.
[0045] In use: Wheat seeds are fed into the screening cylinder 1 through the feed pipe 3 using the feeding hopper 4 for selection. At the same time, the blower 6 is turned on to suck up the dust that is raised during the selection of wheat seeds. The dust is then transported to the collection bucket 9 through the corrugated hose 12 via the conical guide hood 7. During this process, the backflow preventer valve 8 prevents the dust from flowing backward. Excess air in the collection bucket 9 is discharged through the external threaded air outlet pipe 15. The filter cotton 17 located inside the internal threaded sleeve 16 traps the dust in the discharged air, preventing dust from overflowing and ensuring the air pressure balance inside the collection bucket 9.
[0046] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
