Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in figure 1, the dust removing device for the bale plucker comprises a cotton collecting hopper 1, a cotton outlet pipe 11 communicated with the cotton collecting hopper 1 and an air pump 2 communicated with the cotton collecting hopper 1 through a dust suction pipe 3, wherein a filter screen plate 12 is fixed on the inner wall of the cotton collecting hopper 1, so that cotton in the cotton collecting hopper 1 is not easy to enter the dust suction pipe 3.

As shown in fig. 1, the dust suction pipe 3 is square, an activated carbon filter screen 31 and a dust filter plate 32 are fixed in the dust suction pipe 3, the dust filter plate 32 is arranged between the activated carbon filter screen 31 and the cotton collecting hopper 1, micro-dust and a small amount of cotton on the cotton enter the dust suction pipe 3 and are blocked by the dust filter plate 32, and air and a small amount of micro-dust pass through the dust filter plate 32 and pass through the activated carbon filter screen 31, so that secondary filtration of the micro-dust and purification of the air are realized; since the activated carbon filter net 31 has less contact with fine dust, the micropores on the surface thereof are not easily clogged.

As shown in fig. 2, a scraper 33 and a lifting assembly 4 are further arranged in the dust collection pipe 3, and the scraper 33 abuts against the side of the dust filter plate 32, which is far away from the activated carbon filter screen 31; the lifting component 4 comprises a vertical rod 41 fixedly connected to the scraper 33, a pressing plate 42 is fixed at the top end of the vertical rod 41, and a vertical through groove 43 for the vertical rod 41 to be embedded in a sliding manner is formed in the upper side of the dust collection pipe 3. When the pressing plate 42 is pressed down, the scraper 33 will scrape the fine dust and cotton on the surface of the dust filter 32 downward.

As shown in fig. 2, a dust discharging groove 44 is arranged on the lower side of the dust collecting pipe 3 and is positioned right below the scraper 33, a dust collecting box 45 is arranged below the dust discharging groove 44, and the micro dust and cotton scraped by the scraper 33 enter the dust collecting box 45 through the dust discharging groove 44; a limiting ring 46 is fixed on the lower side of the dust suction pipe 3, the dust collection box 45 is inserted in the limiting ring 46, and the dust collection box 45 is not easy to fall off due to the friction force between the outer wall of the dust collection box and the inner wall of the limiting ring 46.

As shown in fig. 2, the lifting assembly 4 further includes a receiving groove 47 formed on the inner wall of the top of the dust suction pipe 3 and a first spring 48 disposed outside the dust suction pipe 3, and two ends of the first spring 48 are respectively and fixedly connected to the vertical rod 41 and the outer wall of the dust suction pipe 3. When the first spring 48 is in a natural state, the scraper 33 is located in the accommodating groove 47, so that the scraper 33 is not easy to influence the air circulation in the dust suction pipe 3, thereby ensuring the dust suction effect of the dust suction pipe 3 on cotton.

As shown in fig. 2, the dust exhaust groove 44 is provided with an opening and closing assembly 5, the opening and closing assembly 5 includes a closing plate 51, a penetrating rod 52 and a second spring 53, the closing plate 51 is attached to the bottom of the dust suction pipe 3, the penetrating rod 52 is fixed to the bottom of the dust suction pipe 3 through a fixing rod 54, the penetrating rod 52 extends along the horizontal direction and penetrates through the closing plate 51, and two ends of the second spring 53 are respectively and fixedly connected to the closing plate 51 and the penetrating rod 52. When the second spring 53 is in a natural state, the closing plate 51 is closed to the dust exhaust groove 44, so that the micro dust and cotton in the dust suction pipe 3 are not easy to float out of the dust exhaust groove 44; after the closing plate 51 moves relative to the dust suction pipe 3 to expose the dust discharge groove 44, the micro dust and cotton on the upper surface of the closing plate 51 are scraped by the bottom of the dust suction pipe 3, thereby improving the cleaning effect of the micro dust and cotton.

As shown in fig. 2 and 3, a wedge block 55 is fixed on the upper side of the closing plate 51, and the upper end of the wedge block 55 is provided with a guide surface 551 inclined towards the dust filter 32; a pressing block 56 is fixed at the lower end of the vertical rod 41, a sliding groove 49 for the pressing block 56 to slide into is formed in the inner wall of the bottom of the dust collection pipe 3, the sliding groove 49 is communicated with the dust discharge groove 44, and the lower end of the pressing block 56 is obliquely arranged and attached to the guide surface 551; two sets of semi-circular grooves 57 are formed in the lower end of the pressing block 56, balls 58 are embedded in the semi-circular grooves 57 in a rolling mode, and the surface portions of the balls 58 protrude out of the semi-circular grooves 57 and abut against the guide surfaces 551. When the pressing plate 42 is pressed down, the balls 58 are pressed against the guide surfaces 551 and urge the wedge-shaped blocks 55 and the closing plate 51 to move away from the dust filter plate 32, so that the dust discharge groove 44 can be exposed by descending the vertical rod 41, and meanwhile, the scraper 33 scrapes the tiny dust and cotton on the dust filter plate 32 into the dust collection box 45; and during the relative movement of the balls 58 and the wedge-shaped blocks 55, the balls 58 roll in the semi-circular grooves 57 and on the guide surfaces 551, so that the sliding friction between the pressing block 56 and the wedge-shaped blocks 55 is converted into rolling friction, thereby facilitating the sliding of the closing plate 51.

The implementation principle of the embodiment is as follows: under the action of the air pump 2, the cotton and the micro-dust on the cotton move towards the dust suction pipe 3, the filter screen plate 12 separates most of the cotton, the micro-dust and a small amount of cotton on the cotton enter the dust suction pipe 3 and are blocked by the dust filter plate 32, and the air and a small amount of micro-dust pass through the dust filter plate 32 and pass through the activated carbon filter screen 31, so that secondary filtration of the micro-dust and purification of the air are realized, and the micro-dust contacted with the activated carbon filter screen 31 is less, so that the micro-pores on the surface of the activated carbon filter screen are not easy to be blocked.

After the air pump 2 is pumped for a period of time, the pressing plate 42 is pressed downwards, the vertical rod 41, the scraper 33 and the pressing block 56 are lowered synchronously, the ball 58 is pressed on the guide surface 551, the wedge-shaped block 55 and the closing plate 51 are driven to move away from the dust filter 32, the dust discharge groove 44 is exposed, and meanwhile, the scraper 33 scrapes the tiny dust and cotton on the dust filter 32 into the dust collection box 45, so that the tiny dust and cotton on the dust filter 32 can be scraped and cleaned conveniently.

When the pressing plate 42 is not pressed, the first spring 48 and the second spring 53 return to the natural state, and the first spring 48 enables the scraping plate 33 to rise into the accommodating groove 47, so that the scraping plate 33 is not easy to influence the air circulation in the dust suction pipe 3, and the dust suction effect of the dust suction pipe 3 on cotton is ensured; the second spring 53 will urge the closing plate 51 to close the dust discharging slot 44, so that the tiny dust and cotton in the dust suction pipe 3 will not easily float out of the dust discharging slot 44.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
