Description

Technical Field

[0001] This utility model relates to a cotton row separating device for a brush roller cotton harvester, belonging to the technical field of external row separators (A01D63 / 00). Background Technology

[0002] The cotton-growing areas in the Yellow River and Yangtze River basins are mainly engaged in small- to medium-scale cotton cultivation. The narrow farm roads make it difficult for large-scale agricultural machinery to adapt, resulting in inconvenience when turning or maneuvering in the fields, and compromising operational efficiency. Therefore, these two major cotton-growing areas currently primarily use brush roller-type lightweight cotton harvesters.

[0003] Existing brush roller cotton harvesters have a triangular fixed-wing row-separating device (also called a row divider or seed divider) at the front of the cotton picking platform. The seed divider has a supporting stalk to hold the cotton branch for picking. However, when the existing row divider picks cotton and holds the cotton branch, the supporting stalk often rubs against the cotton branch, causing the cotton boll to fall and resulting in losses.

[0004] In addition, 1) the existing brush roller cotton harvester's row divider is easily entangled by small cotton branches, shrubs, and debris during operation, affecting the harvesting process; 2) the row divider often snags drip irrigation tape, mulch film, or even hits the ground due to uneven ground, causing foreign fibers to mix into the seed cotton. Both of these situations require manual intervention after stopping the machine, significantly impacting harvesting efficiency. Summary of the Invention

[0005] The first technical problem this utility model aims to solve is how to reduce the loss of cotton that falls off when the cotton splitter picks and supports the cotton branches.

[0006] The second technical problem this utility model aims to solve is how to prevent the row divider from snagging and colliding with drip irrigation tape, mulch film, or even the ground when the cotton harvester is moving.

[0007] The third technical problem this utility model aims to solve is how to prevent the row separator from getting tangled with cotton branches, shrubs, and debris when the cotton harvester is moving.

[0008] The present invention proposes the following technical solution to solve the aforementioned technical problem: a cotton row separator for a brush roller cotton harvester, comprising a front waist bar and a rear waist bar that are vertically erected and substantially parallel to each other. A base plate is connected to the bottom of the front waist bar and the rear waist bar. A triangular tail seat is fixed to the bottom of the rear waist bar on its rearward side. An arc-shaped arm is connected to the bottom of the front end of the front waist bar. A conical front angle plate extending outward is fixed to one side of the front end of the arc-shaped arm. The arc-shaped arm and the conical front angle plate constitute a row-separating cone for separating cotton branches. At least two supporting stems are fixed to the conical front angle plate. A pickup plate is fixedly connected to the base plate on the same side as the arc-shaped arm, at least... The front ends of two stalks are fixed to the upper surface of a conical front corner plate and form an equidistant first gap in a horizontal plane. The middle and rear sections of at least one of the stalks extend inward at an angle to the horizontal plane and bend at a first angle in the inclined plane. The other two stalks bend at a second angle in the horizontal plane. The at least two stalks form a gradually decreasing second gap smaller than the first gap from their bends. The rear sections of the stalks intersect each other in the same projection plane. The pickup plate is located below the rear sections of the at least two stalks, and the rear part of the pickup plate is connected to the inlet of the cotton harvester's brush roller.

[0009] The beneficial effect of this design is that when the front sections of at least two support rods are supporting the cotton, the cotton that is scraped off continues to be scraped and sent to the middle and rear sections of the two support rods in the gap between the two support rods (at the first gap). Since the gap between the two support rods in the middle and rear sections becomes smaller and they are parallel at an angle, the cotton falls from between the two support rods onto the picking plate below. Then, the cotton moves backward on the picking plate and is sent into the brush roller inlet of the cotton harvester.

[0010] The second technical solution proposed by this utility model to solve the above-mentioned technical problem is based on the first technical solution: the front waist bar, the rear waist bar, and the base plate are all made of two parallel strips fixedly connected by bolts, and a strip-shaped groove is formed between the two parallel strips; a sliding wrench is provided in the strip-shaped groove of the base plate, the sliding wrench is close to a triangle with one side of the triangle being arc-shaped and protruding downward from the base plate, and the two ends of the sliding wrench are hinged to the two parallel strips of the base plate; a connecting plate is fixed in the strip-shaped groove of the rear waist bar, the connecting plate has a hole and a rotating shaft passes through the hole, an angle sensor is sleeved on one end of the rotating shaft on one side of the connecting plate, and a rocker arm is hinged to the other end of the rotating shaft on the other side of the connecting plate, and a connecting rod is connected between the rocker arm and the sliding wrench, and the connecting rod is hinged to one end of the rocker arm and the middle of the sliding wrench respectively.

[0011] The second technical solution of this utility model has the following advantages: When the cotton harvester is moving, when the sliding bracket protrudes downward from the triangular arc side of the base plate and collides with the ground, the sliding bracket swings. The swing of the sliding bracket is transmitted to the crank handle through the connecting rod, and the swing angle of the crank handle is the same as the swing angle of the sliding bracket and is identified by the angle sensor on the same rotating shaft. The angle sensor transmits the identified angle to the cotton harvester, and the cotton harvester can then control the raising and lowering of the cotton picking platform and its divider, thereby avoiding snagging and collision with drip irrigation tape, mulch film, and even the ground.

[0012] The present invention proposes a third technical solution to solve the above-mentioned technical problem, based on either the first or second technical solution: the arc-shaped arm is divided into two sections, a forearm and a rear upper arm. The rear end of the forearm is hinged to one end of the rear upper arm at the hinge point to form an enclosing relationship and extends to the rear upper arm for limitation, so that the head-up angle of the forearm and the rear upper arm is an acute angle; the other end of the rear upper arm is hinged to the bottom of the front end of the front waist bar; a flexible chain is provided between the rear upper arm and the front waist bar, one end of the flexible chain is fixed to the rear upper arm, and the other end of the flexible chain is fixed to the front waist bar.

[0013] The beneficial effect of the third technical solution of this utility model is that when the cotton harvester is moving, when the forearm at the front end encounters cotton branches, shrubs and debris, it will rotate at a certain angle along the hinge point of the forearm and the rear arm. Furthermore, due to the elasticity of the soft chain, the rear arm can also rotate at a certain angle along the hinge point of the rear arm and the front arm. In this way, the forearm and the rear arm can avoid getting entangled with cotton branches, shrubs and debris.

[0014] Furthermore, a reinforcing rib is provided between the rear waist bar and the base plate; holes are provided on the pickup plate to remove some leaf debris and dust.

[0015] Furthermore, the straw is made of an elastic material, with its front end fixed to a conical front corner plate by a pressure ring, and its tail end can swing freely.

[0016] Furthermore, the first angle, the second angle, and the included angle are acute angles. Attached Figure Description

[0028] This embodiment provides a cotton row separator for a brush roller cotton harvester, such as... Figure 1 As shown, it is installed at the front end of the cotton picking platform 101 of the brush roller cotton harvester 100. Figure 2 , Figure 3 As shown, the splitter in this embodiment includes a front horizontal bar 1 and a rear horizontal bar 2 that are erected vertically and are basically parallel to each other. A base plate 3 is connected to the bottom between the front horizontal bar 1 and the rear horizontal bar 2. Two protective covers, a front cover 4 and a rear cover 5, are provided on the top between the front horizontal bar 1 and the rear horizontal bar 2. A triangular tailstock 6 is fixed to the bottom of the rear horizontal bar 2 on the rearward side. Figure 1 As shown, the triangular tailstock 6 is fixed to the front end of the cotton picking platform 101, thereby fixing the row divider of this embodiment to the front end of the cotton picking platform 101.

[0029] like Figures 3-7 As shown, an arc-shaped arm 7 is connected to the bottom front end of the front waist bar 1, as... Figure 6 , Figure 7As shown, a tapered front corner plate 8 extending outward is fixed to one side of the front end of the arc-shaped arm 7. The arc-shaped arm 7 and the tapered front corner plate 8 form a dividing cone for separating cotton branches. At least two supporting rods are fixed on the tapered front corner plate 8. In this embodiment, there are two supporting rods, namely the inner supporting rod 9-1 and the outer supporting rod 9-2. One end (front end) of the inner supporting rod 9-1 and the outer supporting rod 9-2 is fixed to the tapered front corner plate 8 by a pressure ring 20. A pickup plate 10 is fixedly connected to the base plate 3 on the same side as the arc-shaped arm 7. The front ends of two supporting poles 9-1 and 9-2 are fixed to the upper surface of the conical front corner plate 8 and form an equidistant first spacing X in a horizontal plane. The middle and rear sections of at least two supporting poles extend backward and bend inward at two different first and second angles respectively. The two supporting poles 9-1 and 9-2 form a gradually decreasing second spacing Y between each other from their bending points. The first angle of the inner supporting pole 9-1 bending obliquely upward at a 20-degree acute angle with the horizontal plane is a 30-degree acute angle. The second angle of the outer supporting pole 9-2 bending in the horizontal plane is a 15-degree acute angle. The second spacing Y is smaller than the first spacing X. Because the inner support rod 9-1 bends upward at a 20-degree angle to the horizontal plane, the two support rods 9-1 and 9-2 intersect each other in the same projection plane (such as the horizontal plane). The pickup plate 10 is located below the rear section of the two support rods 9-1 and 9-2, and the rear part of the pickup plate 10 is connected to the inlet of the cotton harvester's brush roller.

[0030] In this embodiment, a triangular reinforcing rib plate 19 is provided between the rear waist bar 2 and the base plate 3. This embodiment also features a row of elongated waist-shaped holes on the pickup plate 10 to remove some leaf debris and dust; of course, the waist-shaped holes can also be other shapes. The straw in this embodiment is made of an elastic material, with its front end fixed to a conical front corner plate by a pressure ring, and its tail end able to swing freely.

[0031] In operation, when the front sections of the two support stalks 9-1 and 9-2 are supporting the cotton, the cotton that is scraped off continues to be scraped backward through the gap between the two support stalks 9-1 and 9-2 (at the first gap X) to the middle and rear sections of the two support stalks 9-1 and 9-2. As the second gap between the two support stalks gradually decreases in the middle and rear sections, the cotton falls from between the two support stalks 9-1 and 9-2 onto the picking plate 10 below. Then, the cotton moves backward on the picking plate 10 and is fed into the brush roller inlet of the cotton harvester. As the cotton falls onto the picking plate 10, debris and dust continue to fall to the ground through the holes in the picking plate 10. Example 2

[0032] This embodiment of the cotton row separator for a brush roller cotton harvester is a further improvement based on Embodiment 1, such as... Figure 8 and Figure 9 As shown, the differences from Embodiment 1 are as follows: The front waist bar 1, rear waist bar 2, and base plate 3 are all made of two parallel strips fixed together by bolts, and a strip-shaped groove is formed between the two parallel strips. A sliding rocker 11 is provided in the strip-shaped groove of the base plate 3. The sliding rocker 11 is close to a triangle with one side of the triangle being arc-shaped and protruding downward from the base plate 3. The two ends of the sliding rocker 11 are hinged to the two parallel strips of the base plate 3. A connecting plate 12 is fixed in the strip-shaped groove of the rear waist bar 2. The connecting plate 12 has a hole and a rotating shaft 13 passes through the hole. An angle sensor 14 is sleeved on one end of the rotating shaft 13 on one side of the connecting plate 12. A rocker arm 15 is hinged to the other end of the rotating shaft 13 on the other side of the connecting plate 12. A connecting rod 16 is connected between the rocker arm 15 and the sliding rocker 11. The connecting rod 16 is hinged to one end of the rocker arm 15 and the middle of the sliding rocker 11.

[0033] When in use, as the cotton harvester moves, when the sliding jack 11 protrudes downward from the triangular arc side of the base plate 3 and collides with the ground, the sliding jack 11 swings. The swing of the sliding jack 11 is transmitted to the crank handle 15 through the connecting rod 16, and the swing angle of the crank handle 15 is the same as the swing angle of the sliding jack 11 and is identified by the angle sensor 14 on the same rotating shaft 13. The angle sensor 14 transmits the identified angle to the cotton harvester, which can then control the raising and lowering of the cotton picking platform 101 and its row divider, thereby avoiding snagging and collision with drip irrigation tape, mulch film, or even the ground. Example 3

[0034] This embodiment of the cotton row separator for a brush roller cotton harvester is a further improvement based on Embodiment 2, such as... Figure 10 As shown, the differences from Embodiment 2 are as follows: The arc-shaped arm 7 is divided into two sections: a forearm 7-1 and a rear upper arm 7-2. One end of the rear upper arm 7-2 is hinged to the forearm via a joint 17. The forearm 7-1 and the rear upper arm 7-2 form an enclosing relationship at the hinge point and extend to limit the movement towards the rear upper arm 7-2, making the head-up angle of the forearm 7-1 and the rear upper arm 7-2 an acute angle. The other end of the rear upper arm 7-2 is hinged to the bottom front end of the front waist bar 1. A flexible chain 18 is provided between the rear upper arm 7-2 and the front waist bar 1. One end of the flexible chain 18 is fixed to the rear upper arm 7-2, and the other end of the flexible chain 18 is fixed to the front waist bar 1.

[0035] When the cotton harvester is in use, when the forearm 7-1 at the front end encounters cotton branches, shrubs, or debris, it will rotate at a certain angle along the hinge point between the forearm 7-1 and the rear arm 7-2. Furthermore, due to the elasticity of the flexible chain 18, the rear arm 7-2 can also rotate at a certain angle along the hinge point between the rear arm 7-2 and the front waist bar 1. In this way, the forearm 7-1 and the rear arm 7-2 can avoid getting tangled with cotton branches, shrubs, and debris.

[0036] The above description is only a preferred embodiment of this utility model, but the utility model is not limited thereto. For example: 1) the angle between the inner supporting stalk 9-1 and the horizontal plane can be 15 degrees, 25 degrees, 30 degrees or other acute angles; 2) the first angle can be 20 degrees, 25 degrees or other acute angles, and the second angle can be 10 degrees, 12 degrees or other acute angles. All equivalent substitutions or equivalent changes made based on the concept and technical solution of this utility model should be covered within the protection scope of this utility model.
