Description
Technical Field
[0001] This utility model relates to the technical field of grain silo feeding equipment, specifically to a telescopic chute sealing structure for a grain silo feed inlet. Background Technology
[0002] In the agricultural sector, grain is mostly stored in granaries. Granaries can ensure that grain is preserved in a dry and safe environment for a long time, avoiding the adverse effects of dampness, pests, rodents, mold, and other factors.
[0003] In related technologies, grain transport vehicles use onboard grain suction machines to suck the grain from the truck bed. A pipeline is then installed between the grain suction machine and the grain silo to pump the grain from the truck bed into the silo. This method requires no manual operation and greatly improves the efficiency of grain delivery.
[0004] Most existing grain silo feed inlets are equipped with telescopic chutes for conveying grain. The feeding rate can be controlled by adjusting the length of the telescopic chute. However, dust or particulate matter is generated when grain falls into the feed inlet and during the feeding process through the telescopic chute. This dust can spread into the surrounding air through the expansion gaps of the telescopic chute, thus polluting the environment. Although some telescopic chutes are fitted with external telescopic sleeves to protect against dust, the dust accumulated inside the sleeves is not easy to clean. To solve the above problems, a telescopic chute sealing structure for grain silo feed inlets is proposed. Utility Model Content
[0005] In view of this, the present invention provides a telescopic chute sealing structure for the grain silo inlet. The present invention uses a dust exhaust fan on the filter assembly to extract dust from the main and branch dust suction pipes, thereby extracting dust from the air storage ring connected to the branch dust suction pipe, and then extracting dust from the second ventilation ring connected to the air storage ring, and finally extracting dust from the ventilation cavity. This process draws the dust generated during grain feeding to the filter cartridge in the filter assembly, where the dust is filtered by the filter core before being discharged, thus protecting the environment.
[0006] To solve the above-mentioned technical problems, this utility model provides a telescopic chute sealing structure for a grain silo inlet, including a telescopic base connected to the inlet end of the telescopic chute, a discharge pipe connected to the top of the telescopic base, a telescopic tube on the outer surface of the telescopic chute, a discharge base connected to the outlet end of the telescopic chute, a ventilation cavity between the outer walls of the telescopic base and the discharge base, a first ventilation component in the inner ring of the discharge base, a second ventilation component in the inner ring of the telescopic base, a dust suction branch pipe connected to the top of the second ventilation component, a dust suction main pipe connected to the top of the dust suction branch pipe, an external threaded pipe passing through the wall of the discharge pipe in the dust suction main pipe, a filter component at the end of the external threaded pipe away from the discharge pipe, and a support component at the bottom of the filter component.
[0007] The first ventilation component includes a first positioning ring installed on the inner wall of the feeding base. The first positioning ring is used to connect the feeding base and the first ventilation ring. The inner ring of the first positioning ring is provided with a first ventilation ring. The first ventilation ring is used to open a first ventilation port and also to connect the feeding end of the telescopic chute to the feeding base. The surface of the first ventilation ring is provided with a plurality of first ventilation ports. The first ventilation ports are used to allow dust emitted from the grain bin inlet to enter the ventilation cavity. The first ventilation ports are connected to the ventilation cavity.
[0008] The second ventilation assembly includes a second ventilation ring installed on the inner wall of the telescopic base. The second ventilation ring is used to connect and fix the telescopic base to the feed end of the telescopic chute. The second ventilation ring has a hollow interior design, and several second ventilation openings are provided through the surface of the second ventilation ring. The second ventilation openings are used to allow dust in the ventilation cavity to enter the air storage ring. The second ventilation openings are connected to the ventilation cavity. An air storage ring is connected to the top of the second ventilation ring. The air storage ring is used to circulate dust in the ventilation cavity. The bottom of the air storage ring is connected to several second ventilation openings.
[0009] The air collection ring is a hollow circular design, with its top connected to the bottom of the suction tube.
[0010] An opening is provided at the point where the main suction pipe penetrates the feed pipe, allowing dust from the air storage ring to enter the suction cylinder.
[0011] The filter assembly includes an internal threaded cylinder that is threadedly connected to an external threaded pipe. The internal threaded cylinder and the external threaded pipe are threaded together, allowing the internal threaded cylinder to be separated from or connected to the feed pipe. A dust collection cylinder is located at the end of the internal threaded cylinder away from the feed pipe. The dust collection cylinder is used to circulate dust in the main dust collection pipe and the branch dust collection pipe. A dust exhaust fan is located at the end of the dust collection cylinder away from the feed pipe. The dust exhaust fan is used to discharge the dust in the dust collection cylinder into the filter cylinder. The exhaust end of the dust exhaust fan is detachably equipped with a filter cylinder, which is used to purify the dust in the dust collection cylinder.
[0012] The support assembly includes a support plate fixedly mounted to the outer wall of the telescopic base. The support plate is used to connect the telescopic base to the U-shaped bracket. The top of the support plate is provided with a U-shaped bracket, which is used to support the dust collection cylinder on the fixed filter assembly, thereby reducing the stress on the inner threaded cylinder and the outer threaded tube.
[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0014] 1. Dust is dispersed into the telescopic pipe through the feed inlet of the grain silo, or enters the ventilation chamber through the first ventilation component. The dust then disperses within the ventilation chamber. The dust is drawn from the main and branch suction pipes by the dust exhaust fan on the filter component, which in turn draws dust from the air storage ring connected to the branch suction pipe. This process then draws dust from the second ventilation ring connected to the air storage ring, and finally from the ventilation chamber. The dust generated during grain feeding is drawn to the filter cartridge within the filter component. After being filtered by the filter element in the filter cartridge, the dust is discharged, thus protecting the environment.
[0015] 2. When it is necessary to clean the filter cartridge or maintain the dust exhaust fan, the filter assembly can be removed by separating the inner threaded cylinder from the outer threaded pipe for maintenance.
[0016] 3. The support assembly is used to support the dust collection cylinder on the fixed filter assembly, thereby reducing the stress on the inner threaded cylinder and the outer threaded tube. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0023] like Figure 1-4As shown: This embodiment provides a telescopic chute sealing structure for a grain silo inlet, including a telescopic base 101 connected to the inlet end of the telescopic chute 100. A telescopic tube 104 is sleeved on the outer surface of the telescopic chute 100. The telescopic tube 104 is made of corrugated pipe to accommodate the telescopic movement of the telescopic chute 100. An electric lifting rod is provided between the telescopic base 101 and the discharge base 103 to adjust the distance between them. The telescopic base 101 is circular. A cylindrical telescopic base 101 is fixedly connected to the top of a telescopic chute 100.

A second ventilation assembly 300 is provided within the inner ring of the telescopic base 101, for fixedly connecting the lower telescopic base 101 to the feed end of the telescopic chute 100. A dust suction branch pipe 301 is connected to the top of the second ventilation assembly 300. The dust suction branch pipe 301 and the main dust suction pipe 302 are used to extract dust from the air storage ring 306, thereby drawing dust from the ventilation chamber 200 to the air storage ring 306. Inside the filter assembly 400, the top of the suction branch pipe 301 is connected to the suction main pipe 302. The suction main pipe 302 passes through the pipe wall of the feed pipe 102 and is provided with an external threaded pipe 303.

The support assembly 401 is used to fix and support the filter assembly 400 and reduce the stress on the filter assembly 400.
[0024] During use, dust generated when the telescopic chute 100 discharges material is dispersed into the telescopic tube through the inlet of the telescopic chute 100 and the grain bin, or enters the ventilation chamber 200 through the first ventilation component 201, causing the dust to disperse within the ventilation chamber 200. When the telescopic chute 100 is in use, the dust exhaust fan 404 on the filter component 400 is activated, drawing dust from the main suction pipe 302 and the suction branch pipe 301 through the suction pipe, thereby drawing dust from the air storage ring 306 connected to the suction branch pipe 301, drawing dust from the second ventilation ring 304 connected to the air storage ring 306, and finally drawing dust from the ventilation chamber 200. This process draws the dust generated when the grain is discharged to the filter cylinder 405 within the filter component 400, where the dust is filtered by the filter core and then discharged, thus protecting the environment.
[0025] This embodiment provides a telescopic chute sealing structure for the feed inlet of a grain silo.
[0026] like Figure 2 , 3 As shown in Figure 4: The first ventilation component 201 includes a first positioning ring 202 installed on the inner wall of the unloading base 103. The first positioning ring 202 is used for the connection between the unloading base 103 and the bottom ventilation ring.

The first ventilation ports 204 are connected to the ventilation cavity 200.
[0027] Its effect is as follows: the first ventilation component 201 is used to connect and fix the telescopic end of the telescopic chute 100 to the feeding base 103, so that the telescopic chute 100 can be telescopically adjusted along with the electric telescopic rod installed on the feeding base 103.
[0028] like Figure 2 , 3 As shown: The second ventilation assembly 300 includes a second ventilation ring 304 installed on the inner wall of the telescopic base 101. The second ventilation assembly 300 is also used to fix the telescopic base 101 to the telescopic chute 100. The second ventilation ring 304 is welded and fixed to the inner wall of the telescopic base 101. The second ventilation ring 304 is used to connect and fix the telescopic base 101 to the feed end of the telescopic chute 100. The second ventilation ring 304 has a hollow interior design. Several second ventilation ports 305 are provided through the surface of the second ventilation ring 304.

[0029] Its effect is as follows: the second ventilation ring 304 is used to connect and fix the telescopic base 101 to the feed end of the telescopic chute 100, and the air storage ring 306 is used to circulate the dust in the ventilation cavity 200, so that the dust in the ventilation cavity 200 enters the air storage ring 306.
[0030] like Figure 2 , 3 As shown: The air storage ring 306 is a circular ring with a hollow interior. The top of the air storage ring 306 is connected to the lower end of the suction branch pipe 301. The suction main pipe 302 has an opening 307 at the pipe wall where it passes through the feed pipe 102. The opening 307 is sealed and is used to allow the dust in the air storage ring 306 to enter the suction cylinder 403.
[0031] Its effect is that the dust in the air storage ring 306 enters the suction branch pipe 301, then enters the suction main pipe 302 through the suction branch pipe 301, and finally enters the filter assembly 400.
[0032] like Figure 1 , 2 As shown in Figure 3: The filter assembly 400 includes an internal threaded cylinder 402 that is threadedly connected to the external threaded pipe 303. The internal threaded cylinder 402 is threadedly engaged with the external threaded pipe 303. A dust collection cylinder 403 is provided at the end of the internal threaded cylinder 402 away from the discharge pipe 102. The inner wall of the dust collection cylinder 403 is treated with anti-corrosion. The dust collection cylinder 403 is used to circulate dust in the main dust collection pipe 302 and the dust collection branch pipe 301. A dust exhaust fan 404 is provided at the end of the dust collection cylinder 403 away from the discharge pipe 102. The fan 404 is equipped with a support crossbeam and is fixed to the dust collection cylinder 403.

The air outlet of the dust exhaust fan 404 is detachably equipped with the filter cylinder 405. The filter cylinder 405 has a built-in filter element. The filter element and the filter cylinder 405 adopt a separate and detachable design. The filter cylinder 405 is used to purify the dust in the dust collection cylinder 403.
[0033] Its effect is that the internal threaded cylinder 402 can be separated or connected to the feed pipe 102, and the dust exhaust fan 404 is used to discharge the dust in the dust collection cylinder 403 into the filter cylinder 405, thereby filtering the dust and preventing the dust generated during feeding from drifting into the air.
[0034] like Figure 1 , 2As shown in Figure 3: The support assembly 401 includes a support plate 406 fixedly disposed on the outer wall of the telescopic base 101. The support plate 406 is welded and fixed to the outer wall of the telescopic base 101. The support plate 406 is used to connect the telescopic base 101 with the U-shaped bracket 407. A U-shaped bracket is provided on the top of the support plate 406. The U-shaped bracket is in contact with the dust suction pipe. The top of the U-shaped bracket is polished. The U-shaped bracket is used to support and fix the dust suction cylinder 403 on the filter assembly 400, thereby reducing the stress on the inner threaded cylinder 402 and the outer threaded pipe 303.
[0035] Working principle: Dust generated during material feeding through the telescopic chute 100 is dispersed into the telescopic tube through the feed inlet of the telescopic chute 100 and the grain silo, or enters the ventilation chamber 200 through the first ventilation component 201, causing the dust to disperse within the ventilation chamber 200. When the telescopic chute 100 is in use, the dust exhaust fan 404 on the filter component 400 is activated, drawing dust from the main suction pipe 302 and the branch suction pipe 301 through the suction pipe, thereby drawing dust from the air storage ring 306 connected to the branch suction pipe 301, and thus drawing dust from the storage ring 306. Dust flowing through the second ventilation ring 304 connected to the air ring 306 is then drawn from the ventilation chamber 200, thereby drawing the dust generated during grain feeding to the filter cartridge 405 in the filter assembly 400. The dust is then filtered by the filter element in the filter cartridge 405 before being discharged, thus protecting the environment. When it is necessary to clean the filter cartridge 405 or maintain the dust exhaust fan 404, the filter assembly 400 can be removed by separating the inner threaded cylinder 402 from the outer threaded pipe 303 for maintenance.
