Description

A taro harvester and its rubbing, soil-cleaning and impurity-removing device

Technical Field

The invention relates to the technical field of taro harvesting and soil cleaning, in particular to a taro harvester and a rubbing, soil cleaning and impurity removing device thereof.

Background Art

For example, the Chinese patent with the announcement number CN113597872B discloses a kneading, soil-cleaning and debris-removing device for a bagging-type potato combine harvester, a soil-cleaning frame, a hydraulic cylinder, a smooth roller, a kneading roller I, a kneading roller II and a soil-cleaning drive device, wherein the soil-cleaning frame includes a vertical plate, a lug I, a support rod, a reinforcing plate, a debris-cleaning plate, a lug II and a lug III, and the kneading wheel is provided with spiral holes corresponding to each kneading edge, the same number of which is the same as the number of the kneading edges, the pitch and rotation direction of the spiral holes are respectively equal to the pitch and rotation direction of the kneading edges, the cross-section of the spiral holes is an oblong, and the length direction of the oblong is an arc.

However, the above scheme has the following shortcomings: in the above patent, the soil wrapped on the surface of potatoes can be removed by setting the rubbing wheel and the rubbing ridges, and the rubbing effect can be enhanced by setting the smooth rollers between the rubbing rollers. However, since the rubbing wheel is made of elastic material, for dry soil on the surface of crops, this kind of rubbing can ensure that the soil falls off the surface of the crops. However, when the surface of the crops is relatively moist, as the rubbing wheel rotates, the moist soil on the surface of the crops will adhere to the surface of the rubbing wheel, causing the moist soil on the surface of the rubbing wheel to be re-adhered to the surface of the crops when the rubbing wheel is used to clean the soil of other crops. For this reason, we have introduced a taro harvester and a rubbing soil cleaning and impurity removing device thereof.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Please refer to Figures 1-6, the present invention provides a technical solution:

Embodiment 1:

A kneading soil-clearing and impurity-removing device comprises a shell 1, wherein a feed port 16 is provided in the upper end of the shell 1, and taro is collected by a taro harvester and then fed into the feed port 16, and the taro enters the shell 1 through the feed port 16, and a plurality of kneading rollers 2 are provided on the upper and lower sides of the inner side of the shell 1, and the kneading rollers 2 are provided with a cavity, and a limiting shaft 19 is provided between the plurality of kneading rollers 2, and both ends of the limiting shaft 19 are movably connected to the shell 1, and the setting of the limiting shaft 19 prevents small-sized taro from falling into the external environment, and a plurality of groups of rubber scraping rings 18 are fixedly sleeved on the outer side of the kneading rollers 2, and the rubber scraping rings 18 are used to scrape the soil on the surface of the taro. The scraped soil is discharged through the lower side of the outer shell 1. A connecting shaft 3 is fixedly sleeved on the inner side of the kneading roller 2. Two connecting columns 8 are fixedly sleeved on the outer side of the connecting shaft 3. The connecting columns 8 are movably connected in the outer shell 1. When the kneading roller 2 moves, the connecting columns 8 can move in the outer shell 1. The opposite ends of the two connecting columns 8 are fixedly connected to the kneading roller 2. The taro is fed into the outer shell 1 through the feed port 16. The soil and impurities on the surface of the taro are cleared by the kneading rollers 2 arranged on the upper and lower sides. Protective covers 7 are fixedly connected on both sides of the outer shell 1. One end of the connecting shaft 3 extends out of the outer shell 1 and is fixedly connected to the transmission mechanism.

The other end of the connecting shaft 3 extends out of the shell 1 and is fixedly connected to the swing mechanism, and the transmission mechanism enables the upper and lower rubbing rollers 2 to rotate synchronously, and the taro is moved by the rotation of the upper and lower rubbing rollers 2, and the upper and lower rubbing rollers 2 are driven to swing synchronously by the swinging mechanism, and the surface of the taro is rubbed by the upper and lower swinging rubbing rollers 2, and the two ends of the connecting shaft 3 are movably connected in the protective cover 7 respectively, and the back sides of the upper and lower rubbing rollers 2 are in contact with the cleaning brush 17, and the cleaning brush 17 is fixedly connected to the inner side of the shell 1, and the transmission mechanism drives the rubbing rollers 2 to rotate, and the dirt adhered to the surface of the rubbing rollers 2 is cleaned by the cleaning brush 17.

Embodiment 2:

On the basis of Example 1, in order to enable the upper and lower kneading rollers 2 to swing synchronously, an annular clearance cavity 9 is opened in the connecting column 8 near one end of the kneading roller 2, and a retaining ring 21 is slidably connected in the annular clearance cavity 9. One end of the retaining ring 21 is fixedly connected to a connecting spring 10, and the other end of the connecting spring 10 is fixedly connected to the annular clearance cavity 9. The air in the cavity of the kneading roller 2 will enter the annular clearance cavity 9 under the squeezing of the taro, and the air entering the annular clearance cavity 9 will push the retaining ring 21 to move. The retaining ring 21 compresses the connecting spring 10 when moving. When the taro does not squeeze the kneading roller 2, under the elastic force of the connecting spring 10, the air entering the annular clearance cavity 9 will re-enter the cavity in the kneading roller 2, so that the surface of the kneading roller 2 can be quickly reset after being squeezed, while ensuring that the surface of the kneading roller 2 can always be in contact with the surface of the taro.

The transmission mechanism includes a connecting gear 13, which is fixedly sleeved on the outer side of the connecting shaft 3, and the upper and lower connecting gears 13 are meshed with each other. One end of the upper connecting shaft 3 extends out of the protective cover 7 and is fixedly connected to the pulley 12. Several pulleys 12 are connected to each other through belts 11. When the upper connecting gear 13 rotates, it will drive the pulley 12 to rotate. Driven by the belt 11, several pulleys 12 rotate synchronously, so that several groups of rubbing rollers 2 rotate synchronously. A transmission motor 14 is fixedly connected to the upper end of the protective cover 7, and a transmission gear 15 is fixedly connected to the output end of the transmission motor 14. The lower end of the transmission gear 15 extends into the protective cover 7 and meshes with a connecting gear 13 on the upper side. The rotation of the transmission gear 15 drives a connecting gear 13 meshed with it to start rotating. Since the upper and lower connecting gears 13 are meshed with each other, at this time, driven by the transmission gear 15, the two rubbing rollers 2 on the upper and lower sides rotate in opposite directions.

The swing mechanism includes a swing gear 4, which is fixedly sleeved on the outside of the connecting shaft 3. A connecting roller 6 is provided between the upper and lower swing gears 4. Both ends of the connecting roller 6 are movably connected in the protective cover 7. A plurality of groups of teeth 5 are fixedly connected to the upper and lower sides of the connecting roller 6, and the plurality of groups of teeth 5 are meshed with the corresponding swing gear 4. A connecting motor 23 is fixedly connected to the outside of the outer shell 1. The connecting motor 23 extends into the outer shell 1 and is fixedly connected to one end of the connecting roller 6. The connecting motor 23 rotates to drive the connecting roller 6 connected to its output end to start rotating. The connecting roller 6 rotates to drive the plurality of groups of teeth 5 to rotate. When the teeth 5 rotates to the position of the swing gear 4, as the connecting roller 6 continues to rotate, the plurality of groups of teeth 5 will mesh with the corresponding swing gear 4. The upper swing gear 4 moves to the left under the rotation of the connecting roller 6, and the lower swing gear 4 moves to the right under the rotation of the connecting roller 6. When the swing gear 4 moves, it drives the corresponding rubbing roller 2 to move.

One end of the lower connecting gear 13 is fixedly connected to a first return spring 22, which is sleeved on the outside of the connecting column 8, and the end of the first return spring 22 away from the connecting gear 13 is fixedly connected to the outer shell 1, and one end of the upper swing gear 4 is fixedly connected to a second return spring 20, which is sleeved on the outside of the connecting column 8, and the end of the second return spring 20 away from the swing gear 4 is fixedly connected to the outer shell 1. When several groups of teeth 5 are disengaged from the swing gear 4, under the elastic force of the second return spring 20, the upper rubbing roller 2 moves to the right, and under the elastic force of the first return spring 22, the lower rubbing roller 2 moves to the left.

In addition, in order to achieve the above-mentioned purpose, the present invention also provides a taro harvester, including the above-mentioned kneading, soil cleaning and impurity removing device.

Working principle: when in use, turn on the transmission motor 14 and the connecting motor 23. The connecting motor 23 rotates to drive the transmission gear 15 connected to its output end to start rotating. The transmission gear 15 rotates to drive a connecting gear 13 meshing with it to start rotating. Since the connecting gears 13 on the upper and lower sides are meshed with each other, at this time, driven by the transmission gear 15, the two kneading rollers 2 on the upper and lower sides rotate in opposite directions. When the upper connecting gear 13 rotates, it will drive the pulley 12 to rotate. Driven by the belt 11, several pulleys 12 rotate synchronously, so that several groups of kneading rollers 2 rotate synchronously.

The connecting motor 23 rotates to drive the connecting roller 6 connected to its output end to start rotating. The rotation of the connecting roller 6 drives several groups of teeth 5 to rotate. When the teeth 5 rotate to the position of the swing gear 4, as the connecting roller 6 continues to rotate, several groups of teeth 5 will mesh with the corresponding swing gears 4. The upper swing gear 4 moves to the left under the rotation of the connecting roller 6, and the lower swing gear 4 moves to the right under the rotation of the connecting roller 6. When the swing gear 4 moves, it drives the corresponding rubbing roller 2 to move.

When the upper rubbing roller 2 moves to the left, the second return spring 20 is compressed, and the lower rubbing roller 2 moves to the right, so that the first return spring 22 is compressed. When several groups of teeth 5 are disengaged from the swing gear 4, the upper rubbing roller 2 moves to the right under the elastic force of the second return spring 20, and the lower rubbing roller 2 moves to the left under the elastic force of the first return spring 22. When several teeth 5 come into contact with the corresponding swing gear 4 again, the rubbing roller 2 moves again, so that several groups of rubbing rollers 2 on the upper and lower sides swing synchronously.

The taro is collected by the taro harvester and sent to the feed port 16. The taro enters the outer shell 1 through the feed port 16. As the upper and lower rubbing rollers 2 rotate, the taro will be rolled between the upper and lower rubbing rollers 2. The air in the cavity of the rubbing roller 2 will enter the annular give-way cavity 9 under the squeezing of the taro. The air entering the annular give-way cavity 9 will push the baffle ring 21 to move. The baffle ring 21 compresses the connecting spring 10 when moving. When the taro does not squeeze the rubbing roller 2, the air entering the annular give-way cavity 9 will re-enter the cavity in the rubbing roller 2 under the elastic force of the connecting spring 10, so that the surface of the rubbing roller 2 can be quickly reset after being squeezed, while ensuring that the surface of the rubbing roller 2 can always be in contact with the surface of the taro.

The taro can be moved by the rubbing rollers 2 arranged on the upper and lower sides. The rubbing rollers 2 moving back and forth scrape the dirt on the surface of the taro through a plurality of rubber scraping rings 18 arranged on the surface thereof, and the scraped dirt is discharged through the lower side of the outer shell 1. When the relatively moist dirt on the surface of the taro adheres to the surface of the rubbing roller 2, the dirt on the surface of the rubbing roller 2 can be cleaned and discharged through the cooperation of the rotating rubbing roller 2 and the cleaning brush 17. After being rubbed by a plurality of rubbing rollers 2, the taro is discharged through the lower end of the outer shell 1.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
