Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically, it relates to a pneumatic harvesting head structure for long-staple cotton. Background Technology

[0002] With the continuous expansion of cotton planting area, labor shortages and increased costs, the development of mechanized cotton harvesting is imperative.

[0003] Chinese patent CN201282649Y discloses a cotton picking head, which includes a left divider, a right divider, a left picking box, a right picking box, a left bow-tooth picking roller, and a right bow-tooth picking roller. A cotton picking channel is formed between the left and right picking boxes. The left divider and right divider are respectively installed on the left and right picking boxes on both sides of the cotton picking channel inlet. The left and right picking boxes on both sides of the cotton picking channel have left and right picking openings, respectively. The left bow-tooth picking roller is located at the left picking opening, and the right bow-tooth picking roller is located at the right picking opening.

[0004] The above devices are used for picking long-staple cotton seeds with spindle-type cotton pickers. However, this can lead to problems such as reduced fiber length and knotting, which lowers the quality of the long-staple cotton.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a pneumatic picking head structure for long-staple cotton.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] A pneumatic picking head structure for long-staple cotton includes an outer guide, a picking chamber installed on one side of the outer guide, a bottom connecting plate installed at the bottom of the picking chamber, inner guides installed on both inner walls of the picking chamber, and vibration generators installed on opposite sides of the bottom connecting plate.

[0009] The inner guide has a front cotton picking chamber, a middle cotton picking chamber and a rear cotton picking chamber arranged from front to back. The top of the front cotton picking chamber, the middle cotton picking chamber and the rear cotton picking chamber are all equipped with cotton suction pipes. The center of the front and rear ends of the cotton picking chamber is symmetrically provided with cotton plant channels of the same size. The vibration generator is equipped with excitation teeth on one side.

[0010] Optionally, the external guide includes a first inclined baffle and a second inclined baffle installed on both sides of the cotton picking chamber. The first and second inclined baffles are located at the front end of the cotton picking chamber and are arranged symmetrically from left to right. A first mounting plate is installed on one side of each of the first and second inclined baffles. A first through hole is opened on the first mounting plate, and a first bolt is installed in the first through hole. A first threaded hole is opened on both sides of the cotton picking chamber. The first bolt passes through the first through hole and is threaded into the first threaded hole. The first and second inclined baffles on both sides of the external guide are located at the front end of the cotton picking chamber. By moving the cotton picking head in the cotton field, each row of cotton plants can be gathered and guided into the cotton picking chamber.

[0011] Optionally, the inner guide includes a third inclined baffle and a fourth inclined baffle. The third and fourth inclined baffles are respectively installed on the inner walls of the front cotton picking chamber, the middle cotton picking chamber, and the rear cotton picking chamber, and are arranged symmetrically from left to right. A second mounting plate is installed on one side of each of the third and fourth inclined baffles. A second through hole is opened on the second mounting plate, and a second bolt is installed in the second through hole. A second threaded hole is opened on the inner walls of both sides of the front cotton picking chamber, the middle cotton picking chamber, and the rear cotton picking chamber. The second bolt passes through the second through hole and is threaded into the second bolt. Inside the two threaded holes, the inner guides are used in pairs, with a total of 6. The cross-section of the inner guides on both sides is a right-angled triangle. They are located on the inner walls of the front cotton picking bin, the middle cotton picking bin, and the rear cotton picking bin, respectively, and are arranged symmetrically from left to right. When the cotton plant moves from one cotton picking bin to the next, it can gather and press the cotton plant in and immediately release it, causing the cotton plant to vibrate instantly and the seed cotton to fall off the cotton plant. By gathering and pressing the cotton plant in and immediately releasing it when the cotton plant moves in and out of the three cotton picking bins in succession, the seed cotton is released from the cotton plant and enters the suction tube by suction.

[0012] Optionally, suction pipes are installed at the top of and connected to the front, middle, and rear cotton picking chambers. During cotton picking, the cotton plants can enter the picking chamber through the cotton picking head moving through the cotton field, and the seed cotton is pneumatically picked and sucked out of the picking chamber through the suction pipes. The suction pipes are the outlet for the seed cotton and also the outlet for the air in the picking chamber, before exiting the picking chamber.

[0013] Optionally, the bottom connecting plate has multiple first slots on one and both sides, and right-angled bends are installed around the bottom of the cotton picking chamber. Multiple second slots are formed on these right-angled bends, with the first and second slots corresponding to each other. Each of the first and second slots contains a first fixing screw. The bottom connecting plates are used in pairs, with two plates in total. The bottom connecting plates are installed at the bottom of the cotton picking chamber using the first fixing screws to connect and fix the relative position of the cotton picking chamber and the vibration generator. The distance between the opposite end faces of the bottom connecting plates is the same as the width of the cotton plant channels on the front and rear end faces of the cotton picking chamber.

[0014] Optionally, multiple third slots are provided on the other side of the bottom connecting plate, and multiple fourth slots are provided on one side of the vibration generator. The multiple third slots and multiple fourth slots correspond to each other, and a second fixing screw is provided in each of the multiple third slots and multiple fourth slots. The vibration generator is installed on the bottom connecting plate by means of the second fixing screw. The vibration generator is used in pairs on the left and right sides of multiple cotton picking bins, with a quantity of 2. The material is hard alloy, and the excitation teeth are symmetrically arranged with a certain distance between the opposite end faces. The excitation teeth are right trapezoids with a 90° oblique waist angle and arranged in a sawtooth shape. When the cotton picking head moves in the cotton field, the sawtooth vibration generators on both sides continuously collide, squeeze and release with the bottom of the cotton plant, causing the cotton plant to vibrate continuously, thereby reducing the binding force between the seed cotton and the boll and causing the seed cotton to fall off.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0016] This pneumatic picking head structure for long-staple cotton generates airflow in three picking chambers through negative pressure airflow in three suction tubes. The airflow is directed towards the suction tubes. The inner guide's convergence and release, along with the continuous collision and compression release function of the vibration generator, causes the seed cotton on the cotton plant to fall off. The fallen seed cotton is then suspended by the airflow in the picking chambers towards the suction tubes and sucked into the suction tubes. This avoids damage to the long-staple cotton fibers, ensures the quality of the long-staple cotton, and features a simple structure and low cost.

[0017] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

The first bolt passes through the first through hole and is threaded into the first threaded hole. The first inclined baffle 11 and the second inclined baffle 12 on both sides of the external guide 1 are located at the front end of the cotton picking chamber 2. By moving the cotton picking head in the cotton field, each row of cotton plants can be gathered and guided into the cotton picking chamber 2.

[0033] In this embodiment, the inner guide 4 includes a third inclined baffle 41 and a fourth inclined baffle 42. The third inclined baffle 41 and the fourth inclined baffle 42 are respectively installed on the inner walls of the front cotton picking chamber 23, the middle cotton picking chamber 24, and the rear cotton picking chamber 25, and are arranged symmetrically from left to right. A second mounting plate is installed on one side of each of the third inclined baffle 41 and the fourth inclined baffle 42. A second through hole is opened on the second mounting plate, and a second bolt is provided in the second through hole. A second threaded hole is opened on the inner walls of the front cotton picking chamber 23, the middle cotton picking chamber 24, and the rear cotton picking chamber 25, and the second bolt passes through the second threaded hole. The through-hole thread fits in the second threaded hole. The inner guide 4 is used in pairs, with a total of 6. The cross-section of the inner guide 4 on both sides is a right-angled triangle. They are located on the inner walls of the front cotton picking bin 23, the middle cotton picking bin 24 and the rear cotton picking bin 25 respectively, and are arranged symmetrically from left to right. When the cotton plant enters the next cotton picking bin from the previous cotton picking bin, the cotton plant can be gathered and pressed in and then immediately released, causing the cotton plant to vibrate instantly and the seed cotton to fall off the cotton plant. By gathering and pressing in and immediately releasing the cotton plant when it continuously enters and exits the three cotton picking bins, the seed cotton is released from the cotton plant and enters the suction tube 21 through suction.

[0034] In this embodiment, the cotton suction pipes 21 are respectively installed at the top of the front cotton picking chamber 23, the middle cotton picking chamber 24, and the rear cotton picking chamber 25 and are connected to them. When picking cotton plants, the cotton plants can enter the cotton picking chamber 2 through the movement of the cotton picking head in the cotton field, and the seed cotton is pneumatically picked and sucked out of the cotton picking chamber 2 through the cotton suction pipes 21. The cotton suction pipes 21 are the outlet of the seed cotton and also the outlet of the air in the cotton picking chamber 2, and then exit the cotton picking chamber 2.

[0035] In this embodiment, the bottom connecting plate 3 has multiple first slots 31 on one and both sides. The bottom of the cotton picking chamber 2 has right-angled bends 27 around its perimeter, with multiple second slots 22 on the bends 27.
