Description

Technical Field

[0001] This utility model relates to the field of grain dryer technology, and in particular to a dust removal mechanism for a grain dryer. Background Technology

[0002] In recent years, as my country's agricultural production modernization level has been continuously improved, agricultural production efficiency and operation quality have been significantly enhanced, and crop yields have been continuously increasing. This has also led to a continuous increase in the workload of grain drying. Grain drying is a major work link in the processing of grain after harvest. The quality of drying plays a decisive role in the quality of grain storage and the length of storage time. Traditional manual sun-drying is inefficient and time-consuming. The use of grain dryers has greatly improved the efficiency of grain drying.

[0003] Chinese patent document CN113680532A discloses a dust removal mechanism for a grain dryer and a grain dryer, including a dust removal chamber. A feeding funnel is inserted into the top of the dust removal chamber, and a feeding pipe is fixedly connected to the feeding funnel. In use, the grain that needs dust removal is fed through the feeding funnel and the feeding pipe, and finally enters the moving pipe. The grain is blocked by an electrostatic dust removal plate and stays in the moving pipe. The drive motor drives the slider to move through the lead screw. The electrostatic dust removal plate is energized to generate static electricity and begins to attract dust. When the electrostatic dust removal plate moves, it causes the grain to tumble and rotate in the moving pipe, so that the dust on the surface of the grain is attracted by the electrostatic dust removal plate as much as possible. When the slider moves to contact the third contact switch, the electrostatic dust removal plate is de-energized. During this process, the suction fan sucks away and discharges the dust on the electrostatic dust removal plate through the suction pipe, so that the electrostatic dust removal plate can be reused.

[0004] The existing technology has the following problems:

[0005] The dust removal mechanism on this grain dryer involves first placing a portion of the grain into a moving pipe, and then using an electrostatic plate to move along the bottom of the pipe, causing the grain to roll and simultaneously adsorbing dust. However, this method results in a small amount of grain being removed each time, leading to a longer dust removal time and lower efficiency. Utility Model Content

[0006] This invention provides a dust removal mechanism for a grain dryer to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A dust removal mechanism for a grain dryer includes a base frame. A mechanism cylinder is rotatably connected to the upper side of the base frame. Four rectangularly distributed dust outlet pipes are fixedly connected to the left and right sides of the mechanism cylinder near the upper side. Four rectangularly distributed hydraulic rods are rotatably connected to the left and right sides of the mechanism cylinder near the front and rear sides. The lower ends of the hydraulic rods are rotatably connected to the upper side of the base frame near the four corners. Two front-and-back dust suction mechanisms are rotatably connected to the left and right sides of the inner side of the mechanism cylinder near the front and rear sides. An auger is rotatably connected to the bottom center of the left and right sides of the inner side of the base frame. An isolation plate is rotatably connected to the middle of the left and right sides of the base frame. A power mechanism is movably installed on the right side of the mechanism cylinder.

[0009] The dust collection mechanism includes a rotating plate, and two rotating plates are symmetrically distributed on the left and right sides. Several evenly distributed suction rods are fixedly connected to the side of the rotating plates that are close to each other. A cleaning table is movably sleeved on the outside of the suction rods. Several evenly distributed dust removal rings are fixedly sleeved on the inner sides of the left and right walls of the cleaning table.

[0010] Preferably, a number of fans arranged in a ring are fixedly connected to the inner side of the cleaning table.

[0011] Preferably, a number of annularly distributed dust-proof plates are fixedly sleeved on the inner sides of the left and right walls of the cleaning table, and the dust-proof plates are located on the left and right sides of the fan.

[0012] Preferably, a motor is fixedly connected to the inner left side of the cleaning platform near the edge, and a gear is fixedly connected to the output end of the motor. A first guide plate is fixedly connected to the inner right side of the cleaning platform via a boss. A second guide plate is rotatably connected to the inner right side of the cleaning platform, and the second guide plate is located to the right of the first guide plate. A plurality of annularly distributed power components are slidably connected to the inner sides of the second guide plate and the first guide plate. Power wheels are movably installed on the inner sides of each of the power components, and the power wheels are located outside the central suction rod. A gear ring is fixedly connected to the outer side of the second guide plate, and the gear ring and the gear are meshed together.

[0013] Preferably, a rubber sleeve is fixedly fitted onto the outer side of each of the power wheels.

[0014] Preferably, rubber rings are fixedly connected to the sides of the two rotating plates that are close to each other.

[0015] Preferably, the inner side of the mechanism cylinder, the left and right sides of the cleaning table, and the side of the two rotating plates that are close to each other are all provided with a Teflon layer.

[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0017] 1. This utility model provides a dust removal mechanism for a grain dryer, which adopts the cooperation of an auger, a partition plate, a power mechanism, a base frame, a mechanism cylinder, a dust outlet pipe, a hydraulic rod, a dust suction mechanism, a rotating plate, an adsorption rod, a cleaning table, and a dust removal ring. The hydraulic rod drives the mechanism cylinder to rotate, so that the two dust suction mechanisms are alternately submerged in grain, so that one dust suction mechanism performs the dust adsorption operation and the other dust suction mechanism performs the dust removal operation. A large amount of grain can be dusted at one time, which improves work efficiency.

The motor drives the power wheel to clamp the adsorption rod at the center, allowing the cleaning table to move on the adsorption rod when the power component drives the power wheel to rotate. This avoids the problem of prolonged rotation of the lead screw caused by screw drive, which is difficult to wear down and leads to high maintenance costs. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5 As shown, a dust removal mechanism for a grain dryer includes a base frame 1. A mechanism cylinder 2 is rotatably connected to the upper side of the base frame 1. Four rectangularly distributed dust outlet pipes 3 are fixedly connected to the left and right sides of the mechanism cylinder 2 near the upper side. Four rectangularly distributed hydraulic rods 4 are rotatably connected to the left and right sides of the mechanism cylinder 2 near the front and rear sides. The lower ends of the hydraulic rods 4 are rotatably connected to the upper side of the base frame 1 near the four corners. Two front-and-back distributed dust suction mechanisms 5 are rotatably connected to the left and right sides of the inner side of the mechanism cylinder 2 near the front and rear sides. An auger 6 is rotatably connected to the bottom center of the left and right sides of the inner side of the base frame 1. An isolation plate 7 is rotatably connected to the middle of the left and right sides of the base frame 1. A power mechanism 8 is movably installed on the right side of the mechanism cylinder 2.

[0027] The dust collection mechanism 5 includes a rotating plate 51, and two rotating plates 51 are symmetrically distributed on the left and right sides. Several evenly distributed suction rods 52 are fixedly connected to the side of the rotating plates 51 that are close to each other. A cleaning table 53 is movably sleeved on the outside of the suction rods 52. Several evenly distributed dust removal rings 54 are fixedly sleeved on the inner sides of the left and right walls of the cleaning table 53.

[0028] It should be noted that the power mechanism 8 consists of multiple electric motors, which drive the rotating plate 51, the auger 6 and the isolation plate 7 to rotate. The hydraulic rod 4 on one side retracts and the hydraulic rod 4 on the other side extends, causing the mechanism cylinder 2 to swing back and forth, so that the grain inside the mechanism cylinder 2 moves back and forth inside the mechanism cylinder 2. A discharge pipe is provided on the right side of the upper front position of the mechanism cylinder 2, and a discharge pipe is provided on the left side of the lower front position of the mechanism cylinder 2 for discharging and discharging materials. The adsorption rod 52 relies on static electricity to adsorb dust. After the power is cut off, the cleaning table 53 moves on the adsorption rod 52, so that the dust is cleaned.

[0029] like Figure 4 As shown, several ring-shaped fans 55 are fixedly connected to the inner side of the cleaning table 53.

[0030] It should be noted that the fan 55 is used to blow air during dust cleaning, causing the dust to be stirred up and easily sucked into the dust outlet pipe 3.

[0031] like Figure 4 As shown, several annularly distributed dust-proof plates 56 are fixedly fitted onto the inner sides of the left and right walls of the cleaning table 53, and the dust-proof plates 56 are located on the left and right sides of the fan 55.

[0032] It should be noted that the dustproof plate 56 is used to isolate the fan 55 to prevent some grains from entering the fan 55 when the adsorption rod 52 is adsorbing dust, thus affecting the operation of the fan 55.

[0033] like Figure 5As shown, a motor 57 is fixedly connected to the inner left side of the cleaning table 53 near the edge. A gear 58 is fixedly connected to the output end of the motor 57. A first guide plate 59 is fixedly connected to the inner right side of the cleaning table 53 via a boss. A second guide plate 510 is rotatably connected to the inner right side of the cleaning table 53, and the second guide plate 510 is located to the right of the first guide plate 59. Several ring-shaped power components 511 are slidably connected to the inner sides of the second guide plate 510 and the first guide plate 59. Power wheels 512 are movably installed on the inner sides of the power components 511, and the power wheels 512 are located outside the central suction rod 52. A gear ring 513 is fixedly connected to the outer side of the second guide plate 510, and the gear ring 513 and the gear 58 are meshed together.

[0034] It should be noted that the second guide plate 510 is provided with an arc-shaped groove, and the first guide plate 59 is provided with a straight groove. The power assembly 511 slides in both grooves at the same time. The motor 57 drives the gear 58 to rotate, which causes the gear 58 to drive the gear ring 513 to rotate, which causes the cleaning table 53 to drive the second guide plate 510 to rotate, causing the power assemblies 511 to move closer or further apart, causing the power wheel 512 to contact the suction rod 52, which causes the power assembly 511 to drive the power wheel 512 to rotate, which in turn causes the power wheel 512 to drive the cleaning table 53 to move on the suction rod 52.

[0035] like Figure 5 As shown, rubber sleeves are fixedly fitted to the outer sides of several drive wheels 512.

[0036] It should be noted that the rubber sleeve is used to increase the friction between the power wheel 512 and the adsorption rod 52, while avoiding rigid contact between the power wheel 512 and the adsorption rod 52, which could cause damage to either the adsorption rod 52 or the power wheel 512.

[0037] like Figure 3 As shown, rubber rings are fixedly connected to the sides of the two rotating plates 51 that are close to each other.

[0038] It should be noted that the rubber ring is used to seal the gap between the rotating plate 51 and the cleaning table 53 to prevent dust from entering during dust discharge, which would make it difficult to remove some of the dust.

[0039] like Figure 2 As shown, the inner side of the mechanism cylinder 2, the left and right sides of the cleaning table 53, and the side of the two rotating plates 51 that are close to each other are all provided with Teflon layers.

[0040] It should be noted that Teflon is non-dust-absorbing and wear-resistant, preventing dust accumulation and wear on these parts.

[0041] The working principle of this utility model is as follows: First, the power mechanism 8 consists of multiple electric motors, which drive the rotating plate 51, the auger 6, and the isolation plate 7 to rotate. One side of the hydraulic rod 4 retracts, and the other side of the hydraulic rod 4 extends, causing the mechanism cylinder 2 to swing back and forth, allowing the grain inside the mechanism cylinder 2 to move back and forth. A discharge pipe is located on the right side of the upper, slightly forward position of the mechanism cylinder 2, and an outlet pipe is located on the left side of the lower, slightly forward position of the mechanism cylinder 2 for discharging and discharging materials. The suction rod 52 relies on static electricity to attract dust. After power is cut off, the cleaning table 53 moves on the suction rod 52, cleaning the dust. The hydraulic rod 4 drives the mechanism cylinder 2 to rotate, causing the two suction mechanisms 5 to be alternately submerged in grain, resulting in one suction mechanism 5 performing dust adsorption and the other performing dust removal. This allows for the simultaneous dust removal of a large amount of grain, improving work efficiency. Finally, the second guide plate 510 has an arc-shaped groove, and the first guide plate 59 has a straight groove. The power assembly 5... Simultaneously sliding within two slots, motor 57 drives gear 58 to rotate, causing gear 58 to drive gear ring 513 to rotate, which in turn causes sweeping table 53 to drive second guide plate 510 to rotate, causing power components 511 to move closer or further apart, causing power wheel 512 to contact suction rod 52, causing power component 511 to drive power wheel 512 to rotate, and power wheel 512 to drive sweeping table 53 to move on suction rod 52. Rubber sleeve is used to increase the friction between power wheel 512 and suction rod 52, while avoiding rigid contact between power wheel 512 and suction rod 52, which could cause damage to either suction rod 52 or power wheel 512. By having motor 57 drive power wheel 512 to clamp the central suction rod 52, sweeping table 53 can move on suction rod 52 when power component 511 drives power wheel 512 to rotate. This avoids the problem of long-term rotation of screw drive caused by screw drive, and the difficulty in applying wear-resistant treatment to the screw surface, which leads to greater wear and higher maintenance costs.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
