Description

Technical Field

[0001] This utility model relates to the field of cotton grabbing machine technology, and in particular to a dust removal and filtration mechanism for a disc-type cotton grabbing machine. Background Technology

[0002] A cotton grabber is a mechanical device used to grab, convey, and loosen fibrous materials such as cotton.

[0003] Reference patent CN214496569U discloses a dust removal device for a disc-type cotton picker, which includes a cotton suction hood and a cotton conveying pipe connected to the inside of the cotton suction hood. The cotton suction hood is provided with an outer cover and a collection mechanism. The cotton suction hood is located inside the outer cover, and the inner wall of the outer cover and the outer wall of the cotton suction hood together form a collection cavity. The inner wall of the cotton suction hood is provided with a number of filter holes connected to the collection cavity. The collection mechanism includes a collection bucket provided on the cotton suction hood and an activated carbon disc embedded in the collection bucket. The activated carbon disc divides the inside of the collection bucket into a dirt removal cavity and a cleaning cavity arranged sequentially from top to bottom. The collection bucket is provided with an air duct connected to the dirt removal cavity and the collection cavity, and a fan connected to the cleaning cavity.

[0004] The aforementioned patent relies solely on vacuum adsorption to hold cotton material inside the cotton suction hood, making it difficult to hold a large amount of cotton material at once. Furthermore, insufficient adsorption force during the transfer process can easily cause the cotton material to fall off. To address the shortcomings of the aforementioned technology, we propose a disc-type cotton grabber dust removal and filtration mechanism. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dust removal and filtration mechanism for a disc-type cotton grabber.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dust removal and filtration mechanism for a disc-type cotton grabber includes a disc-type cotton grabber cover. A dust removal and filtration mechanism is installed on the upper side of the disc-type cotton grabber cover, and a clamping assembly is installed on the side of the disc-type cotton grabber cover. The dust removal and filtration mechanism includes a pressure equalization cylinder, a dust collection box is fixedly installed on the upper side of the pressure equalization cylinder, and an air pump is fixedly installed on the upper side of the dust collection box. The clamping assembly includes three sets of sealing cylinders, and an air suction pipe is installed between the sealing cylinders and the dust collection box. A valve plate is slidably installed on the inner wall of the sealing cylinder. Three corresponding sets of folding plates are provided on the side of the disc-type cotton grabber cover. A pull rope is connected between the valve plate and the bottom of the outer end of the folding plate. A clamping groove is opened on the inner side of the folding plate.

[0008] Furthermore, the disc-shaped cotton-grabbing cover has three rotating grooves equidistantly spaced on its side circumference, the folding plate is rotatably installed inside the rotating groove, and a sealing corrugated plate is sealingly connected between the folding plate and the inner wall of the rotating groove.

[0009] By adopting the above technical solution, the setting of the sealing corrugated plate maintains the sealing of the inner side of the rotating groove, so that the inner side of the disc-type cotton grabbing cover can stably maintain the vacuum adsorption effect and avoid insufficient negative pressure caused by air leakage in the rotating groove.

[0010] Furthermore, the sealing corrugated plate is made of rubber.

[0011] Furthermore, a fixed side plate is fixedly connected to the inner end of the sealing cylinder, and the fixed side plate is fixedly installed on the side wall of the pressure equalizing cylinder.

[0012] By adopting the above technical solution, the fixed side plate provides a fixed support for the pressure equalizing cylinder.

[0013] Furthermore, a sliding cylinder is fixedly installed at the bottom of the sealing cylinder, and the pull rope slides through the sliding cylinder.

[0014] Furthermore, a rotating shaft is provided on the lower side of the rotating groove, and the rotating shaft is rotatably mounted on the side wall of the disc-shaped cotton-grabbing cover, with the pull rope loop passing through the rotating shaft.

[0015] By adopting the above technical solution, the rotating shaft provides guidance for the pull rope, reducing wear on the pull rope.

[0016] Furthermore, the pressure equalizing cylinder has several dust suction holes at its bottom, and a vertical connecting pipe is connected between the pressure equalizing cylinder and the bottom of the inner side of the dust collection box, with the upper end of the vertical connecting pipe extending above the bottom of the dust collection box.

[0017] Furthermore, a sealed door is rotatably installed on the front side of the dust collection box.

[0018] By adopting the above technical solution, the dust inside the dust collection box can be cleaned by opening the sealed box door.

[0019] Furthermore, a frame is fixedly installed on the inner wall of the dust collection box, a dust filter is fixedly installed on the inner side of the frame, and a sealing strip is adhered to the outer side of the frame, the sealing strip being in contact with the sealed box door.

[0020] Furthermore, the suction end of the air pump is connected to the inside of the dust collection box, and an exhaust pipe is installed on the upper side of the air pump.

[0021] By adopting the above technical solution, when the air pump draws air, it can make the inside of the dust collection box into a negative pressure state, which in turn makes the inside of the pressure equalizing cylinder below into a negative pressure state, and the dust suction hole at the bottom of the pressure equalizing cylinder into a negative pressure state, which is used to perform vacuum adsorption on the fabric. At the same time, the dust suction hole can suck the dust in the cotton into the pressure equalizing cylinder, and finally suck it into the dust collection box for collection.

[0022] Compared with related technologies, the dust removal and filtration mechanism for a disc-type cotton grabber proposed in this utility model has the following beneficial effects:

[0023] In this utility model, the dust removal and filtration mechanism of the disc-type cotton grabber, through the dust removal and filtration mechanism and clamping components, can create a negative pressure state at the suction hole at the bottom of the pressure equalizing cylinder after the air pump is started, which is used for vacuum adsorption of the fabric. At the same time, the suction hole can suck the dust in the cotton into the pressure equalizing cylinder, providing a dust removal effect on the cotton, and finally sucking it into the dust collection box for collection. Meanwhile, an air suction pipe is connected to the side wall of the dust collection box. When the dust is being sucked out of the dust collection box, the valve plate inside the pressure equalizing cylinder will slide upward under the negative pressure, thereby driving the pull rope to pull the folding plate upward and rotate the inner end of the folding plate towards the inside of the disc-type cotton grabber cover, thereby clamping the cotton adsorbed inside the disc-type cotton grabber cover, preventing the cotton from falling off during the vacuum adsorption and transfer process, improving the stability of the disc-type cotton grabber cover in grabbing the cotton, and enhancing its practicality.

[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.

[0031] Reference Figures 1-5 A dust removal and filtration mechanism for a disc-type cotton grabber includes a disc-type cotton grabber cover 1, a dust removal and filtration mechanism 2 on the upper side of the disc-type cotton grabber cover 1, and a clamping assembly 3 on the side of the disc-type cotton grabber cover 1. The dust removal and filtration mechanism 2 includes a pressure equalization cylinder 21, a dust collection box 22 fixedly installed on the upper side of the pressure equalization cylinder 21, an air pump 24 fixedly installed on the upper side of the dust collection box 22, the air pump 24's air extraction end being connected to the inside of the dust collection box 22, and an exhaust pipe 25 connected to the upper side of the air pump 24. The clamping assembly 3 includes three sets of sealing cylinders 32, an air suction pipe 33 connected between the sealing cylinders 32 and the dust collection box 22, a valve plate 37 slidably installed on the inner wall of the sealing cylinders 32, three corresponding folding plates 34 on the side of the disc-type cotton grabber cover 1, a pull rope 35 connecting the valve plate 37 and the bottom of the outer end of the folding plate 34, and a clamping groove 39 opened on the inner side of the folding plate 34.

[0032] In this embodiment, three rotating grooves 11 are equidistantly opened on the side circumference of the disc-type cotton-grabbing cover 1. The folding plate 34 is rotatably installed inside the rotating groove 11. A sealing corrugated plate 12 is sealed between the folding plate 34 and the inner wall of the rotating groove 11. The sealing corrugated plate 12 is made of rubber.

[0033] With the above structure, the sealing corrugated plate 12 is made of rubber and can adapt to deformation as the folding plate 34 rotates, thereby keeping the inside of the rotating groove 11 sealed and ensuring that the inside of the disc-type cotton-grabbing cover 1 can stably maintain vacuum adsorption, avoiding insufficient negative pressure caused by air leakage in the rotating groove 11.

[0034] In this embodiment, a fixed side plate 31 is fixedly connected to the inner end of the sealing cylinder 32. The fixed side plate 31 is fixedly installed on the side wall of the pressure equalizing cylinder 21. A slide cylinder 38 is fixedly installed at the bottom of the sealing cylinder 32. The pull rope 35 slides through the slide cylinder 38. A rotating shaft 36 is provided on the lower side of the rotating groove 11. The rotating shaft 36 is rotatably installed on the side wall of the disc-type cotton grabbing cover 1. The pull rope 35 is sleeved and passes through the rotating shaft 36.

[0035] Through the above structure, both the slide 38 and the rotating shaft 36 provide guidance for the pull rope 35.

[0036] In this embodiment, the pressure equalizing cylinder 21 has several dust suction holes 26 at its bottom. A vertical connecting pipe is connected between the pressure equalizing cylinder 21 and the bottom of the inner side of the dust collection box 22. The upper end of the vertical connecting pipe is higher than the bottom of the dust collection box 22. A sealing box door 23 is rotatably installed on the front side of the dust collection box 22.

[0037] With the above structure, the sealed door 23 can be opened to clean the dust inside the dust collection box 22.

[0038] In this embodiment, a frame 28 is fixedly installed on the inner wall of the dust collection box 22, a dust filter 27 is fixedly installed on the inner side of the frame 28, and a sealing strip 29 is glued to the outer side of the frame 28, which is in contact with the sealed box door 23.

[0039] With the above structure, the sealing strip 29 ensures that the side of the frame 28 and the sealing door 23 are tightly fitted when the sealing door 23 is closed, preventing dust from entering the upper side of the dust filter through gaps and preventing dust from entering the working chamber of the air pump 24.

[0040] In this invention, during use, the disc-shaped cotton-grabbing cover 1 is positioned to grab cotton material. At this time, the folding plate 34 is in a drooping state under its own weight, with its inner end far from the inner wall of the disc-shaped cotton-grabbing cover 1. The clamping groove 39 does not clamp the cotton material. The valve plate 37 inside the sealing cylinder 32 is positioned near the bottom. The air flow in the suction pipe 33 is smooth. The air pressure inside the pressure equalizing cylinder 21 and the dust collection box 22 is basically the same as the outside air pressure. The suction pump 24 is not started. When the suction pump 24 is started, it draws air from the inside of the dust collection box 22 through its suction end, causing the dust collection box 22 to become airy. A negative pressure state is quickly formed inside. Since the pressure equalizing cylinder 21 is connected to the bottom of the dust collection box 22, the inside of the pressure equalizing cylinder 21 also becomes negative pressure. At this time, the several dust suction holes 26 opened at the bottom of the pressure equalizing cylinder 21 are in a negative pressure state, and begin to produce a vacuum adsorption effect on the cotton material below, adsorbing the cotton material to the inner wall of the disc-type cotton grabbing cover 1. At the same time, during the adsorption of cotton material, the dust in the cotton material is also sucked into the pressure equalizing cylinder 21 by the dust suction holes 26, and enters the dust collection box 22 through the connecting channel. As the negative pressure in the dust collection box 22 continues to be generated, the air in the sealed cylinder 32 is drawn into the dust collection box 22 through the suction pipe 3. 3 is drawn into the dust collection box 22, causing a decrease in air pressure inside the sealing cylinder 32. Under the action of the air pressure difference, the valve plate 37 slides upward on the inner wall of the sealing cylinder 32. During the upward sliding of the valve plate 37, the pull rope 35 pulls the folding plate 34 to rotate upward around the rotating groove 11. Since the folding plate 34 and the inner wall of the rotating groove 11 are sealed and connected by the sealing corrugated plate 12, the rotation of the folding plate 34 will not affect the sealing performance of the inner side of the rotating groove 11. The inner side of the disc-type cotton grabbing cover 1 can still maintain a stable vacuum adsorption state. When the folding plate 34 rotates upward, its inner end gradually moves towards the inner side of the disc-type cotton grabbing cover 1. The device rotates until the cotton material adsorbed on the inner wall of the disc-type cotton grabbing cover 1 is clamped in the clamping groove 39. After the cotton material is clamped by the folding plate 34, the disc-type cotton grabbing cover 1 can move according to the overall operation of the cotton grabbing machine to transfer the grabbed cotton material to the designated position. During this process, the air pump 24 continues to work, and the dust suction hole 26 continues to absorb the dust in the cotton material, ensuring that the cotton material is continuously dusted during the transfer process. The dust collection box 22 continuously collects dust. Due to the clamping effect of the folding plate 34, the situation of cotton material falling off due to insufficient vacuum suction force is effectively avoided, thus improving the stability of cotton grabbing.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
