Description

TECHNICAL FIELD

[0001] The present application relates to a backpack cotton picking machine and its use method. BACKGROUND

[0002] The patent No. 201721676441.9 discloses a backpack cotton picking machine, which can press the cotton in the collecting box to make the collecting box load more cotton, so as to reduce the replacement frequency of the collecting box and improve the cotton picking efficiency.

[0003] The backpack cotton picking machine of the patent comprises: a picking machine for picking cotton and provided with a cotton outlet pipe at the top, a transparent collecting box provided at the rear side of the picking machine, the top of the front side wall and communicated with the cotton outlet pipe through a joint and used for collecting cotton, an end cover provided at the bottom of the collecting box and openable and closable, a pressing plate assembly provided in the collecting box and used for pressing the cotton in the collecting box (the pressing plate assembly comprises: a first pressing plate, a second pressing plate sleeved at the rear end of the first pressing plate, and a spring compressed between the first pressing plate and the second pressing plate), a pressing driving mechanism for driving the pressing plate assembly to rotate and press (the pressing driving mechanism comprises: a rotating shaft connected with the rear end of the second pressing plate and penetrating through the front and rear side walls of the collecting box, a first support fixedly arranged on the inner surface of the rear side wall of the collecting box and used for supporting the rotating shaft, and a rotating rod connected with the outer end of the rotating shaft), and a pressing guide mechanism for guiding the pressing plate assembly to rotate and press (the pressing guide mechanism comprises: a rotating shaft connected with the front end of the first pressing plate, and a pair of sliding rails arranged on the inner side wall of the collecting box and slidably matched with the rotating shaft and used for limiting the movement track of the rotating shaft).

[0004] The principle of the backpack cotton picking machine of the patent comprises:

[0005] The picking machine picks cotton and inputs the cotton into the collecting box; the cotton pressing action is performed multiple times during the cotton picking process, each time the pressing driving mechanism is operated to perform the cotton pressing action when the collecting box is about to be filled with cotton, and the cotton picking is paused each time the cotton pressing action is performed, and the cotton picking is continued after the cotton pressing action is completed;

[0006] Each time the pressing driving mechanism is operated to perform the cotton pressing action, the user drives the pressing plate assembly (the first pressing plate + the second pressing plate) to fully press the cotton in the collecting box by pressing the rotating rod, and then the user lifts the rotating rod to drive the pressing plate assembly to rise and reset, so as to continue picking cotton and inputting the cotton into the collecting box;

[0007] By performing the cotton pressing action multiple times, the collecting box can load more cotton, the replacement frequency of the collecting box can be reduced, and the cotton picking efficiency can be improved.

[0008] Although the backpack cotton harvester of this patent can perform multiple pressing actions on the cotton during the cotton harvesting process, the pressing plate assembly needs to be lifted and reset after each pressing action. After the pressing plate assembly is lifted and reset, the pressed cotton may still bounce back and expand. That is, after the pressing plate assembly is lifted and reset, the pressed cotton cannot maintain a compacted state. Therefore, the cotton pressing solution of this patent needs to be improved.

[0014] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0015] The specific technical solution of this invention is as follows:

[0016] like Figure 1As shown, the present invention provides a backpack cotton harvester, comprising: a harvester 1 for harvesting cotton and having a cotton outlet pipe 2 at the top; a transparent collection box 10 for collecting cotton, located at the top of the rear and front side walls of the harvester 1 and connected to the cotton outlet pipe 2 via a connector 3; an openable and closable end cap 11 located at the bottom of the collection box 10; an air bladder 20 fixed at the top of the top wall of the collection box 10; an air supply pipe 21 and a pressure gauge 22 connected to the outer top wall of the collection box 10 and respectively connected to the air bladder 20; an air pump 23 installed on the air supply pipe 21; a flat pressure plate 24 fixed at the bottom of the air bladder 20, located above the connector 3, and slidingly engaged with the inner surfaces of the four side walls of the collection box 10; multiple strip-shaped insertion holes 25 arranged vertically at equal intervals on the rear side wall of the collection box 10 and extending laterally to both ends of the rear side wall of the collection box 10; and a tube for penetrating one of the strip-shaped insertion holes 25 and... The vertically dividing cavity of the collection box 10 includes insert plates 26, which are located on the inner surfaces of the left and right side walls of the collection box 10, corresponding one-to-one with the plurality of strip-shaped insertion holes 25, and at the same height as the corresponding strip-shaped insertion holes 25. Multiple pairs of slots 27 extend laterally to the front and rear side walls of the collection box 10 for inserting the insert plates 26. Also included are multiple strip-shaped plugs 28, each corresponding to one of the plurality of strip-shaped insertion holes 25, which are inserted into and seal the corresponding strip-shaped insertion hole 25. Each strip-shaped plug 28 has a pull rope 29 fixed to its outer end, and each pull rope 29 has a pull ring 30 fixed to its outer end. A net bag is located on the outer surface of the left and / or right side walls of the collection box 10 for loading the insert plates 26. The insert plates 26 are housed in the net bag. The highest strip-shaped insertion hole 25 is lower than and closer to the connector 3. The lowest strip-shaped insertion hole 25 is higher than and closer to the end cap 11.

[0017] The present invention also provides a method of using the above-mentioned backpack cotton picking machine, including: picking machine 1 picking cotton and inputting cotton into collection box 10; performing multiple cotton pressing actions during the cotton picking process, each time when the collection box 10 is almost full of cotton, and pausing cotton picking each time cotton pressing action is performed, and continuing cotton picking after the cotton pressing action is completed.

[0018] Each time the cotton-pressing action is performed: if the insert plate 26 is already inserted into the collection box 10, the insert plate 26 is first pulled out of the collection box 10; then the air pump 23 inflates the air bag 20 through the air supply pipe 21, causing the air bag 20 to expand and drive the pressure plate 24 to press down the cotton in the collection box 10 until the pressure gauge 22 detects that the air pressure of the air bag 20 has reached the predetermined pressure; at this time, the pressure plate 24 fully presses down the cotton in the collection box 10, compacting the cotton in the collection box 10; then the strip-shaped insert 25 that is lower than and closest to the pressure plate 24 is selected, and the strip plug 2 is inserted into the strip-shaped insert 25. 8. Pull out; then insert the insert plate 26 into the strip-shaped insertion hole 25, and insert the insert plate 26 into a pair of slots 27 corresponding to the strip-shaped insertion hole 25, until the front end of the insert plate 26 abuts against the inner surface of the front side wall of the collection box 10; at this time, the insert plate 26 vertically separates the inner cavity of the collection box 10; then the air pump 23 evacuates the air bag 20 through the air supply pipe 21, causing the air bag 20 to contract and drive the pressure plate 24 to move upward and reset, so as to continue picking cotton and input cotton into the collection box 10; and after the pressure plate 24 moves upward and resets, the insert plate 26 inserted in the collection box 10 can prevent the cotton below it from popping open and expanding.

[0019] As can be seen from the above, the present invention can press down the cotton in the collection box 10 to allow the collection box 10 to load more cotton; it can also prevent the cotton from bouncing and expanding after being pressed down to the greatest extent through the insert plate 26, which can further increase the cotton loading capacity of the collection box 10, thereby further reducing the replacement frequency of the collection box 10 and further improving the cotton harvesting efficiency.

[0020] This invention is a partial improvement on the backpack cotton harvester disclosed in Chinese Patent Application No. 201721676441.9. The main improvement is the elimination of: the pressure plate 24 assembly (which includes: a first pressure plate 24, a second pressure plate 24 sleeved at the rear end of the first pressure plate 24, and a spring compressed between the first and second pressure plates 24) located inside the collection box 10 and used to press down the cotton in the collection box 10; and the pressing drive mechanism (which includes: a spring connected to the second pressure plate 24) that drives the pressure plate 24 assembly to rotate and press down. The pressure plate 24 is connected to a rotating shaft at its rear end and passes through the front and rear side walls of the collection box 10. A first support is fixed to the inner surface of the rear side wall of the collection box 10 and used to support the rotating shaft. A rotating rod is connected to the outer end of the rotating shaft. A pressing guide mechanism (including a rotating shaft connected to the front end of the first pressure plate 24 and a pair of slide rails disposed on the inner side wall of the collection box 10, slidingly engaged with the rotating shaft and used to limit the movement trajectory of the rotating shaft) is used instead of an airbag 20, pressure plate 24, and insert plate 26. This invention does not improve other parts of the patent. Other parts of the backpack cotton harvester can be referred to in the specification of the patent and will not be described in detail here (if the end cover 11 is to be opened to take out the cotton in the collection box 10, the insert plate 26 should be pulled out of the collection box 10 before opening the end cover 11).

[0021] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
