Description

Technical Field

[0001] The present invention relates to a tea picking machine, in particular to a tea picking machine that facilitates the transfer of tea leaves. Background Art

[0002] Our company has been engaged in the planting and processing of tea leaves for a long time and has long realized the importance of mechanized tea planting. Therefore, our company began to explore mechanized tea planting early on and successfully developed an all-terrain tea picking, pruning, fertilizing, and pesticide spraying machine suitable for the terrain of the southwestern region, and applied for relevant patents for protection, with the patent application number being 202310130490.6. After being put into use, we have continuously designed and modified the mechanized tea picking equipment and developed a third-generation multi-functional tea picking machine, and applied for relevant patents for protection, with the patent application number being 202311722402.8. After use, we found that there are still some deficiencies in the use of this third-generation multi-functional tea picking machine. Mainly during the tea picking process, it is necessary to sleeved a tea leaf collection bag at the arc-shaped channel outlet of the tool structure to collect tea leaves. After the tea leaves are filled, the tied tea leaf collection bag is manually transferred to the shelf. Each tea leaf collection bag weighs over 100 catties when filled with tea leaves, and two people are required to transfer the tea leaf collection bag to the shelf. This results in at least two workers (one of whom is a driver) being required for each device. Each time after the tea leaves are filled, the vehicle needs to stop to complete the transfer work of the tea leaf collection bag, which not only delays time, but also for the extra worker, during the whole process, in addition to participating in the transfer work of the tea leaf collection bag, other work is only to complete the sleeving work of the tea leaf collection bag, making the worker idle for a certain period of time. In the current situation of extremely scarce labor, this undoubtedly causes a great waste of human resources. Summary of the Invention

[0003] The purpose of the present invention is to provide a tea picking machine that facilitates the transfer of tea leaves. During the tea picking process, the tea picking machine of the present invention can automatically collect tea leaves into a collection frame. When the collection frame is full of tea leaves, the collection frame can be lifted and rotated open, so that the tea leaves in the collection frame automatically fall into the cargo box of the transport truck, improving the tea picking efficiency, and only one driver is required to complete the whole operation during the whole process.

Detailed implementation manners

[0017] The present invention will be further described below in conjunction with the drawings and embodiments, but it shall not be used as a basis for limiting the present invention.

[0018] Embodiments of the present invention: A tea picking machine convenient for tea leaf transportation, comprising a traveling device 1. The front end of the traveling device 1 is fixedly connected to the vehicle head part 3 via a support frame 2. The traveling device 1 and the vehicle head part 3 are both prior arts, and their structures will not be described again here. Both the left and right sides of the rear end of the traveling device 1 are connected to one end of a double-headed hydraulic cylinder 4. The other end of each double-headed hydraulic cylinder 4 is fixedly connected to a middle mounting frame 5. The head end of the middle mounting frame 5 is fixedly connected to the tail end of the vehicle head part 3. A gas chamber 6 is fixedly connected to the front side wall of the cylinder body of the two double-headed hydraulic cylinders 4. The bottom of the head end of the gas chamber 6 is fixed on the top surface of the tool structure 7. A tea leaf conveying channel 8 is also vertically installed on the gas chamber 6. The bottom of the rear side wall of the tea leaf conveying channel 8 is an arc-shaped plate 9 extending forward. The arc-shaped plate 9 extends into the gas chamber to form the front side plate of the gas chamber 6. There is a gap between the arc-shaped plate 9 and the surface of the tool structure 7, and this gap forms an air flow channel 10. At the same time, the left and right side plates of the gas chamber 6 are fixedly connected to the left and right side plates of the tool structure 7, and the left and right side plates of the tea leaf conveying channel 8 are also fixedly connected to the left and right side plates of the tool structure 7. A transition plate 11 extending obliquely backward is provided on the surface of the tool structure 7 in front of the air flow channel 10. The transition plate 11 is located above the head end of the arc-shaped plate 9 and there is also a gap between them. A vertically upward fixed guide rail 12 is installed on the rear side wall of the cylinder body of each double-headed hydraulic cylinder 4. An active guide rail 13 is movably arranged in each fixed guide rail 12. An active frame 14 is movably arranged between the two active guide rails 13. The left and right sides of the active frame 14 are movably clamped into the two active guide rails 13. A collection box 15 is arranged on the active frame 14. A tea leaf inlet 16 is provided on the front end face of the collection box 15. When the collection box 15 is not lifted, the outlet of the tea leaf conveying channel 8 is directly opposite to the tea leaf inlet 16 of the collection box 15. The active guide rail 13 is connected to the fixed guide rail 12 and the active frame 14 respectively through two driving mechanisms.

[0019] During the use of the tea picking machine of the present invention, the driver sits in the driver's seat of the vehicle head part 3 to operate the tea picking machine. During the tea picking process, the tool structure 7 shears the tea leaves. The tea picking machine moves forward. Under the action of inertia, the sheared tea leaves fall onto the surface of the tool structure 7 and are conveyed backward along the transition plate and fall onto the arc-shaped plate 9 of the tea leaf conveying channel 8. At the same time, the high-pressure air flow in the gas chamber can only be sent out along the air flow channel 10. When the high-pressure air flow is sent forward, it is blocked by the transition plate 11 and can only be blown backward from the gap between the transition plate 11 and the arc-shaped plate 9. Under the action of the high-pressure air flow, the tea leaves falling onto the surface of the arc-shaped plate 9 are sent into the tea leaf conveying channel 8, and finally the tea leaves are blown out from the outlet of the tea leaf conveying channel 8 and fall into the collection box 15 from the tea leaf inlet 16, thus realizing the automatic collection of tea leaves. Compared with the third-generation equipment, there is no need to set up tea leaf collection bags anymore.

[0020] When a certain amount of tea leaves are collected in the collecting frame 15, the driver drives the tea plucker to the truck transporting the tea leaves, and through the combined action of the two driving mechanisms, the movable guide rail 13 and the movable frame 14 are lifted at the same time, and finally the bottom of the collecting frame 15 is higher than the top of the truck cargo box, and then the collecting frame 15 is opened, so that the tea leaves in the collecting frame 15 automatically fall into the truck cargo box, so that the tea leaves collected by the tea plucker are quickly transferred to the truck. After the truck is loaded with a certain amount of tea leaves, the tea leaves are transported to the processing factory for processing.

[0021] The fixed guide rail 12 and the movable guide rail 13 are both U-shaped steel structures. A roller 17 is provided on the outer wall of the movable guide rail 13. The roller 17 is inserted into the U-shaped groove of the fixed guide rail 12 and abuts against the two side walls of the U-shaped groove to facilitate the up and down movement of the movable guide rail 13. A lifting hydraulic cylinder 18 is provided on the outer wall of the fixed guide rail 12, and the top of the push rod of the lifting hydraulic cylinder 18 is connected to the top of the movable guide rail 13. The movable frame 14 includes a door frame 19, and rollers 17 are also provided on the left and right side walls of the door frame 19. The rollers 17 are inserted into the U-shaped grooves of the movable guide rails 13. A bracket 20 extending horizontally outward is fixedly connected to the bottom of the door frame 19, and a collecting frame 15 is supported on the bracket 20. The top front end of the collecting frame 15 is hingedly connected to the top cross bar of the door frame 19, and the bottom front end of the collecting frame 15 is hingedly connected to a collecting frame bottom plate 35. The left and right outer walls of the collecting frame 15 are each connected to the movable frame 14 via a collecting frame driving mechanism; the bottom of the movable frame 14 is connected to one end of a lifting chain 21, and the other end of the lifting chain 21 is fixed to the outer wall of the fixed guide rail 12 after being guided by the pulley at the top of the movable guide rail 13.

[0022] When the tea picking machine is driven to the truck and the movable guide rail 13 and the movable frame 14 need to be lifted, the push rod of the lifting hydraulic cylinder 18 is pushed out, thereby driving the movable guide rail 13 to move upward along the fixed guide rail 12. Since one end of the lifting chain 21 is fixed to the fixed guide rail 12, when the movable guide rail 13 is lifted, the pulley thereon moves upward along with the movable guide rail 13, and the pulley forms a movable pulley. When the lifting hydraulic cylinder 18 is pushed out to a height of L, the lifting chain 21 is lifted to a height of 2L, and the lifting chain 21 drives the movable frame 14 to move upward along the movable guide rail 13 to a height of 2L, so that the movable frame 14 can be lifted to a higher height, ensuring that the lifting height of the movable frame 14 can be higher than the height of the truck cargo box. When the bottom height of the movable frame 14 is higher than the top height of the truck cargo box, the tea plucker is moved backwards so that the collecting frame 15 is completely located above the truck cargo box. Then, under the driving action of the collecting frame driving mechanism, the collecting frame 15 is rotated around the hinged end with the movable frame 14 by a certain angle. At this time, the collecting frame bottom plate 35 is no longer supported on the bracket 20. Under the action of gravity, the collecting frame bottom plate 35 rotates open to form a Figure 3In the shown structure, the tea leaves collected in the collection box 15 can automatically fall into the truck cargo box at this time, thus realizing the automatic transfer of tea leaves.

[0023] The collection box driving mechanism is two collection box driving hydraulic cylinders 22, one is arranged on each of the left and right side walls of the collection box 15. The two ends of the collection box driving hydraulic cylinder 22 are respectively connected to the collection box 15 and the diagonal strut 23. The two ends of the diagonal strut 23 are respectively fixedly connected to the bracket 20 and the gantry 19. When it is necessary to rotate and open the collection box 15, the push rod of the collection box driving hydraulic cylinder 22 is pushed out, which can drive the collection box 15 to rotate a certain angle, so that the bottom plate 35 of the collection box automatically opens. In addition to being used to install the collection box driving hydraulic cylinder 22, the diagonal strut 23 can also be used to strengthen the connection between the bracket 20 and the gantry 19, and prevent the bracket 20 from deforming under the gravity of the collection box 15. Reinforcing members 33 are cross - arranged inside the gantry 19 to strengthen the connection strength of the entire gantry 19 and make the structure of the gantry 19 more stable.

[0024] Walking wheels 24 are also arranged on the outer wall of the movable guide rail 13, so that the movable guide rail 13 can quickly move up and down under the driving action of the lifting hydraulic cylinder 18. The tops of the two fixed guide rails 12 on the left and right sides are connected to the support rod 25. An installation support frame 26 is arranged on the top of the movable guide rail 13. When the push rod of the lifting hydraulic cylinder 18 is not pushed out, the bottom of the installation support frame 26 is supported on the support rod 25, so as to support the movable guide rail 13, the movable frame 14 and the collection box 15 through the support rod 25, avoid the lifting hydraulic cylinder 18 from bearing pressure, and at the same time, the support rod 25 connects the two fixed guide rails 12 on the left and right together to make its structure more stable. A metal net 27 is arranged between the upper frames of the collection box 15. On the one hand, it is convenient for ventilation to prevent the tea leaves from being suffocated. On the other hand, it is also convenient for the driver to observe the tea leaf collection situation in the collection box 15.

[0025] A height sensor 28 is also vertically fixed on the outer wall of the cylinder body of the double - headed hydraulic cylinder 4. For tea trees of different heights, it is necessary to adjust the shearing height of the tool structure 7. When the shearing height of the tool structure changes, the height of the corresponding tea leaf conveying channel 8 will also change. And the outlet of the tea leaf conveying channel 8 is directly opposite to the tea leaf inlet 16 of the collection box 15, so the height of the collection box 15 also needs to be adjusted correspondingly. Therefore, the air chamber 6 and the fixed guide rail 12 are respectively fixedly arranged on the two side walls of the cylinder body of the double - headed hydraulic cylinder 4. When the height of the cylinder body of the double - headed hydraulic cylinder 4 changes, the heights of the air chamber 6, the tool structure 7, the tea leaf conveying channel 8, the fixed guide rail 12, the movable guide rail 13, the movable frame 14 and the collection box 15 will be adjusted correspondingly, so that the outlet of the tea leaf conveying channel 8 is always directly opposite to the tea leaf inlet 16 of the collection box 15. A guide rod 29 is vertically arranged on the middle mounting frame 5, and the fixed guide rail 12 is movably sleeved on the guide rod 29 through a connecting plate to ensure the stability of the upper structure of the fixed guide rail 12 and prevent shaking in the horizontal plane direction.

[0026] A fan 30 is installed on the air chamber 6. The air outlet of the fan 30 is communicated with the air chamber 6 through a pipeline, and high-pressure air flow is provided to the air chamber 6 by the fan 30.

[0027] Oblique air outlet holes 31 are arranged at intervals along the width direction of the arc-shaped plate 9. A guiding cone 32 is arranged on the arc-shaped plate 9 on the outer surface of the oblique air outlet holes 31. A part of the air flow in the air chamber 6 is blown out through the air flow channel 10, while a part is blown out through the oblique air outlet holes 31. The air flow blown out from the air flow channel 10 enables the tea leaves to enter the tea leaf conveying channel 8 along the arc-shaped plate 9, and the air flow blown out from the oblique air outlet holes 31 can enhance the acting force for upward conveying of the tea leaves, ensuring that the tea leaves can finally be blown out from the outlet of the tea leaf conveying channel 8. The guiding cone 32 can prevent sundries from falling into the oblique air outlet holes 31, causing blockage of the oblique air outlet holes 31 or the air chamber 6. The width of the tea leaf conveying channel 8 gradually decreases from the inlet upwards, forming a structure with a wider lower part and a narrower upper part. The wider lower part is mainly to match the width of the entire cutter structure 7, ensuring that the tea leaves sheared by the cutter structure 7 can all enter the tea leaf conveying channel 8. The inlet of the tea leaf conveying channel 8 is an arc-shaped structure extending forward, and the outlet is an arc-shaped structure extending backward, so as to be directly opposite to the tea leaf inlet 16 of the collection box.

[0028] The tea leaf conveying channel 8 vertically penetrates upwards through the middle of the left and right middle mounting frames 5. An oil tank 34 is installed on the middle mounting frame 5. The oil tank 34 is adjusted from the previous front part 3 to the middle mounting frame 5, which is more convenient for installation and makes more reasonable use of space.
