Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery and equipment, and specifically relates to a tea tree branch and leaf pruning and crushing-returning integrated machine and a crushing-returning-to-field method. Background Art

[0002] In the prior art, pruning tea branches is a necessary task in common tea garden management. When pruning branches in conventional tea gardens, workers usually hold chainsaws and sweep them across the tea trees for pruning. This method has the following defects: First, it requires manual hand-held bulky chainsaws, which consumes a lot of effort for workers, the number of pruning per day is limited, and the pruning work efficiency is low; second, chain saw pruning lacks protective devices, and the exposed saw chain is prone to accidental injuries, posing a great safety hazard; third, the pruned branches are usually swept to the ground in the tea garden for returning to the field. The process of returning thicker branches to the field is relatively slow, and they are piled up in the tea ridges, which brings inconvenience to tea farmers. If you want to quickly and fully utilize the pruned branches, you need to organize manual work to pick up and collect them, and then concentrate on crushing and composting them before returning them to the field, which consumes a lot of manpower and increases production costs.

[0003] A Chinese patent with publication number "CN106211934B" discloses a pulverizing and returning machine to the field, including a straw pulverizer, a working body and a power device, wherein the straw pulverizer is installed at the inner center of the working body, and fixed brackets are respectively provided on the upper and lower sides of the straw pulverizer, an electric power extractor is provided on the upper left side of the straw pulverizer, a suction channel is provided on the lower left side of the electric power extractor, a suction fan is installed on the right side of the straw pulverizer, a working case is installed on the upper right side of the outside of the working body, the power device is installed on the upper inside of the working case, a CNC actuator is installed on the lower left side of the power device, an electric energy storage device is provided on the right side of the power device, a rolling track is installed on the lower outside of the working body, and a straw cutting device is installed below the suction channel.

[0004] The above patent sets a straw cutting device to make the straw cutting faster during the process of returning the straw to the field. However, during the operation of the device in the above patent, there is a sequence for cutting and returning the straw to the field. The cut straw needs to be transported to the bottom of the powerful suction device through a small rough conveyor belt, and then sucked into the straw crusher through the powerful suction device. During the whole process, when the device is bumpy due to the uneven ground of the tea garden, it is easy to cause the cut branches transported on the small rough conveyor belt to fall off, thereby reducing the effect of crushing and returning the branches to the field. At the same time, due to the different lengths and thicknesses of the cut branches, the channel is prone to blockage during the continuous suction and transportation of the powerful suction device. Summary of the invention

[0005] In order to make up for the shortcomings of the prior art, the present invention provides a tea tree branch and leaf pruning and crushing and returning to the field all-in-one machine and a crushing and returning to the field method to solve the technical problems of cut branches falling off due to the sequence of branch cutting and transportation, and the different lengths and thicknesses of the cut branches easily leading to blockage of the transportation channel.

[0006] To achieve the above purpose, the specific technical solutions of the present invention are as follows: In a first aspect, a tea tree branch and leaf pruning and crushing machine includes a frame body and a crushing and pruning box installed on the top of the frame body. A walking module is installed at the bottom of the frame body for driving the frame body to walk in the tea field.

[0007] The crushing and pruning box is provided with a pruning assembly, a strip-strip-strip-transporting assembly and a crushing and returning assembly which are sequentially arranged on the top of the frame body. A pruning driving assembly is provided on one side of the crushing and pruning box for driving the synchronous operation of the pruning assembly and the strip-strip-transporting assembly.

[0008] The pruning assembly and the strip-stripping and transporting assembly are both installed at the port of the crushing and pruning box. The pruning assembly can prune the branches on the tea tree during the walking process of the frame body, and synchronously transport the pruned broken branches to the inside of the crushing and pruning box through the strip-stripping and transporting assembly.

[0009] The crushing and returning-to-the-field component is used for crushing the collected broken branches, and after crushing, throwing the crushed branches into the tea field.

[0010] Furthermore, the crushing and returning assembly includes a power drive assembly, and a layering combing assembly and a crushing assembly arranged in sequence in the crushing and trimming box. The power drive assembly is used to drive the layering combing assembly and the crushing assembly to work synchronously.

[0011] The layering combing assembly is rotatably connected to the crushing and pruning box, and is used to comb and compress the broken branches that are pruned and enter the crushing and returning box. The crushing assembly is used to crush the compressed broken branches and throw them into the tea field through the crushing and returning port after crushing.

[0012] Furthermore, the press strip combing assembly includes a press strip roller and a plurality of press roller ribs arranged on the press strip roller. Arc-shaped slide grooves are provided on both side walls of the crushing and trimming box. A transfer shaft matching the arc-shaped slide groove is provided at both ends of the press strip roller. The transfer shaft passes through the arc-shaped slide groove and can slide and rotate in the arc-shaped slide groove.

[0013] Furthermore, the crushing assembly includes a crushing roller, a crushing bottom knife and a roller blade. A crushing chamber matched with the crushing roller is provided on the crushing pruning box. The crushing roller is rotatably connected in the crushing chamber. A crushing notch is provided on the crushing roller. The roller blade is installed in the crushing notch and can cooperate with the crushing bottom knife during the rotation process to crush the broken branches.

[0014] Furthermore, the power drive assembly includes a crushing motor and a crushing gear box. The crushing gear box is provided with a transmission gear set and a power gear set. The transmission gear set and the power gear set are connected through a crushing transmission shaft. The crushing motor is connected to the transmission gear set. The pressure roller and the crushing hob are both connected to the power gear set.

[0015] Furthermore, the trimming assembly includes a limiting knife seat and a trimming blade installed at the bottom of the limiting knife seat. The trimming blade is arranged along the length direction of the trimming inlet. A crank slider mechanism is arranged between the trimming blade and the trimming drive assembly, which can drive the trimming blade to reciprocate in the horizontal direction during operation.

[0016] Furthermore, the strip-strip transport assembly includes a plurality of combing rotors and a plurality of hook-shaped strips. Each combing rotor is rotatably connected to the crushing and pruning box. Each hook-shaped strip is sequentially arranged on each combing rotor. The hook-shaped strips on the combing rotor extend out of the pruning inlet during the rotation process, thereby realizing the storage and transport of the pruned branches.

[0017] Furthermore, the trimming drive assembly includes a trimming drive motor and a trimming and combing gear box. The trimming and combing gear box is provided with a driving gear and a plurality of mutually meshing driven gears. The trimming drive motor is mounted on the trimming and combing gear box, and the output shaft is connected to the driving gear. The crank slider mechanism on one side of the trimming blade and each combing rotor can rotate synchronously under the drive of each driven gear.

[0018] Furthermore, the crushing and trimming box is provided with two transmission channels. The two transmission channels are provided with crushing and returning components. There are two combing rotors in total. The two combing rotors rotate in opposite directions during the rotation process. The hook-shaped strips on the two combing rotors are staggered in the vertical direction.

[0019] In the second aspect, a method for crushing and returning tea leaves to the field using the integrated machine for pruning and crushing tea leaves as described in the first aspect is adopted, and the specific steps are as follows: Step 1: Move the device to the tea field to be pruned. The walking module at the bottom of the device enters the aisles on both sides of the tea field and drives the device to move along the tea field.

[0020] Step 2: Start the pruning drive assembly, which drives the pruning blade in the pruning assembly and the combing rotor in the strip transport assembly to move synchronously. The pruning blade reciprocates in the horizontal direction to prune the tea tree branches on the device's path. At the same time, the hook-shaped strip on the combing rotor hooks the pruned broken branches and transports them into the crushing pruning box.

[0021] Step 3: Start the power drive assembly, which drives the layering roller in the layering combing assembly and the crushing roller in the crushing assembly to move synchronously. The layering roller rotates under the drive of the power drive assembly to comb and compress the broken branches entering the crushing pruning box. The crushing roller rotates under the drive of the power drive assembly, and the crushing roller blade and the crushing bottom knife cooperate to crush the pruned branches, and then throw the crushed branches to the outside.

[0022] Step 4: The walking module drives the device to continue moving forward and repeats steps 2 and 3, thereby completing the pruning, crushing and returning operations of the tea tree branches in the entire tea field.

[0023] Compared with the prior art, the present invention has the following advantages: 1. The present invention provides a pruning drive assembly to drive the pruning blade in the pruning assembly and the combing rotor in the stripping transport assembly to move synchronously, so that when the pruning blade prunes the tea branches on the travel path of the device, the hook-shaped strips on the combing rotor hook the pruned branches and transport them to the crushing pruning box. While avoiding the falling of the pruned branches due to the transport of the conveyor belt, the synchronous movement of the pruning blade and the combing rotor improves the efficiency of the device in pruning the tea branches.

[0024] 2. The present invention provides arc-shaped chutes on both side walls of the crushing and pruning box. Adapter shafts matching the arc-shaped chutes are provided at both ends of the pressure strip roller. The adapter shaft passes through the arc-shaped chutes and can slide and rotate in the arc-shaped chutes. During operation, when pruning branches of different sizes enter the compression channel, the pressure strip roller will be adaptively lifted under the drive of the pruning branches, effectively avoiding the compression channel from being blocked due to too many pruning branches entering.

DETAILED DESCRIPTION

[0027] In the description of the present invention, it is necessary to understand that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "center", "end", "length", "outer end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] like Figure 1 and 2 As shown, a tea tree branch and leaf pruning and crushing and returning machine includes a frame body 1, and a pruning component 2, a stripping and transporting component 3, and a crushing and returning component 4 arranged in sequence on the top of the frame body 1. Among them, a walking module 5 is installed at the bottom of the frame body 1 to drive the frame body 1 to walk in the tea field. A crushing and pruning box 6 is fixed on the top of the frame body 1. The crushing and pruning box 6 is a shell structure with open ends. The two ports of the crushing and pruning box 6 are divided into a pruning feed port and a crushing and returning port.

[0030] The pruning assembly 2 and the stripping and transporting assembly 3 are both installed at the pruning inlet. The pruning assembly 2 can prune the branches on the tea tree while the frame body 1 is moving, and the pruned branches are transported to the inside of the crushing and pruning box 6 through the stripping and transporting assembly 3. The crushing and returning assembly 4 is used to crush the collected branches and throw them into the tea field through the crushing and returning opening after crushing, so as to achieve the purpose of crushing and returning the tea branches to the field.

[0031] In this embodiment, a trimming driving assembly 7 is provided on one side of the crushing and trimming box 6 for driving the trimming assembly 2 and the strip-stripping and transporting assembly 3 to operate synchronously.

[0032] Specific structure such as Figure 2 , 3 As shown in Figure 5, the pruning assembly 2 includes a limiting knife seat 2-1 and a pruning blade 2-2 installed at the bottom of the limiting knife seat 2-1. The pruning blade 2-2 is arranged along the length direction of the pruning inlet. During operation, each pruning blade 2-2 reciprocates in the horizontal direction under the drive of the pruning drive assembly 7, thereby achieving the purpose of pruning the branches on the tea tree.

[0033] The strip transport assembly 3 includes two combing rotors 3-1 and a plurality of hook-shaped strips 3-2. Both combing rotors 3-1 are rotatably connected to the crushing and pruning box 6. The hook-shaped strips 3-2 are arranged on each combing rotor 3-1 in sequence. The hook-shaped strips 3-2 on the two combing rotors 3-1 extend out of the pruning inlet during the rotation process, thereby realizing the storage and transport of the pruned branches.

[0034] In this embodiment, the hook-shaped organizing strips 3 - 2 on the two combing rotors 3 - 1 are arranged in a staggered manner in the vertical direction, so as to avoid collision between the hook-shaped organizing strips 3 - 2 on the two combing rotors 3 - 1 during movement.

[0035] Furthermore, two transmission channels are provided on the crushing and pruning box 6. The two transmission channels are provided with crushing and returning components 4, which can compress, crush and throw the broken branches back into the field when they are input. The two combing rotors 3-1 rotate in opposite directions during the rotation process, so that the broken branches input from the pruning inlet can be guided by the hook-shaped strips 3-2 on the two combing rotors 3-1 and transported to the two transmission channels respectively, so as to achieve the purpose of branch diversion.

[0036] like Figure 4 and 5 As shown, the trimming drive assembly 7 includes a trimming drive motor 7-1 and a trimming and combing gear box 7-2. The trimming and combing gear box 7-2 is provided with a driving gear 7-3 and a plurality of mutually meshing driven gears. The trimming drive motor 7-1 is mounted on the trimming and combing gear box 7-2, and the output shaft is connected to the driving gear 7-3.

[0037] In the present embodiment, each driven gear is divided into a combing drive gear 7-4 for driving the two combing rotors 3-1 to rotate and a trimming drive gear 7-5 for driving each trimming blade 2-2 to reciprocate horizontally. Among them, a crank slider structure is provided between the trimming drive gear 7-5 located at the end and the trimming blade 2-2, so that when the trimming drive gear 7-5 rotates, the crank slider structure can convert the rotational force into a horizontal reciprocating force, thereby realizing the reciprocating cutting of the trimming blade 2-2. A rotating gear is fixed to the bottom of the two combing rotors 3-1. Each rotating gear is meshed with the combing drive gear 7-4. The two combing rotors 3-1 can rotate synchronously driven by the rotating gear. Further, the combing drive gears 7-4 between the two combing rotors 3-1 are an even number, thereby realizing the purpose of the two combing rotors 3-1 rotating in opposite directions.

[0038] like Figure 2 and 6 As shown, the crushing and returning assembly 4 includes a power drive assembly 8, and a layering combing assembly 9 and a crushing assembly 10 arranged in sequence in the crushing and pruning box 6. Among them, the power drive assembly 8 is used to drive the layering combing assembly 9 and the crushing assembly 10 to work synchronously. The layering combing assembly 9 is used to comb and compress the broken branches pruned into the crushing and returning box, so as to facilitate the subsequent crushing process. The crushing assembly 10 is used to crush the compressed broken branches and throw them into the tea field through the crushing and returning port after crushing.

[0039] like Figure 7 As shown, the layering combing assembly 9 includes a layering roller 9-1 and a plurality of pressure roller ribs 9-2 arranged on the layering roller 9-1. The layering roller 9-1 is rotatably connected to the side wall of the crushing and pruning box 6. A compression channel with a gradually decreasing height is formed between the outer wall of the layering roller 9-1 and the bottom surface of the crushing and pruning box 6, so that the pruned branches can be gradually compressed in the process of passing through the compression channel, which is convenient for the subsequent crushing of the crushing assembly 10. In this embodiment, each pressure roller rib 9-2 is evenly distributed along the circumference of the axis of the layering roller 9-1, which can increase the friction between the layering roller 9-1 and the broken branches when the layering roller 9-1 rotates, thereby achieving the purpose of stable transportation.

[0040] Furthermore, arc-shaped slide grooves 11 are provided on both side walls of the crushing and pruning box 6. Adapter shafts matching the arc-shaped slide grooves 11 are provided at both ends of the pressure strip roller 9-1. The adapter shaft passes through the arc-shaped slide groove 11 and can slide and rotate in the arc-shaped slide groove 11. During operation, when pruning branches of different sizes enter the compression channel, the pressure strip roller 9-1 will be adaptively lifted under the drive of the pruning branches, effectively avoiding the compression channel from being blocked due to too many pruning branches entering.

[0041] like Figure 6 and 8As shown, the crushing assembly 10 includes a crushing roller 10-1, a crushing bottom knife 10-2 and two roller blades 10-3. Among them, a crushing chamber matched with the crushing roller 10-1 is provided on the crushing trimming box 6. The crushing roller 10-1 is rotatably connected in the crushing chamber. The crushing roller 10-1 is provided with two crushing notches. The two roller blades 10-3 are respectively installed in the two crushing notches.

[0042] During operation, when the pruned branches enter the crushing chamber under the push of the layering roller 9-1, the pruned branches extend into the crushing notch. The crushing roller 10-1 is driven to rotate by the power drive assembly 8, and the crushing process of the pruned branches is achieved with the cooperation of the roller blade 10-3 and the crushing bottom knife 10-2. The branches crushed by the roller blade 10-3 and the crushing bottom knife 10-2 enter the crushing notch and rotate synchronously with the crushing roller 10-1. When it rotates to one side of the crushing return to the field mouth, under the action of centrifugal force, the crushed branches are thrown to the crushing return to the field mouth, thereby achieving the purpose of crushing and returning to the field.

[0043] In this embodiment, two symmetrically arranged return pipes 12 are provided on the crushing return port. The outer ports of the return pipes 12 are offset to both sides, so that the crushed branches thrown out through the crushing return port can fall into the aisle between the tea trees under the guidance of the return pipes 12, thereby achieving the purpose of crushing and returning to the field.

[0044] like Fig. 9 As shown, the power drive assembly 8 includes a crushing motor 8-1 and a crushing gear box 8-2. Among them, the crushing gear box 8-2 is provided with a power input end and two power output ends. The crushing motor 8-1 is installed on the power input end, and is used to input power to the crushing gear box 8-2. The two power output ends are divided into a layering drive end and a crushing drive end. Among them, the layering drive end is connected to the adapter shaft on the layering roller 9-1 through a belt drive. The crushing hob 10-1 is connected to the crushing drive end and can rotate under the drive of the crushing drive end.

[0045] In this embodiment, the crushing gear box 8-2 is provided with a transmission gear set 8-3 and a power gear set 8-4. The transmission gear set 8-3 and the power gear set 8-4 are connected by a crushing transmission shaft. The transmission gear set 8-3 and the power gear set 8-4 each include a plurality of first driving gears meshing with each other. Among them, the output shaft of the crushing motor 8-1 is connected to the first driving gear at the top of the transmission gear set 8-3. The pressure roller 9-1 is connected to the first driving gear at the top of the power gear set 8-4 by a belt transmission. The crushing hob 10-1 is connected to the first driving gear at the bottom of the power gear set 8-4.

[0046] Furthermore, the crushing gearbox 8-2 is in a mountain-shaped structure. Two power gear sets 8-4 are shared. The two power gear sets 8-4 are symmetrically arranged in the crushing gearbox 8-2, and can simultaneously provide power to the layering combing assembly 9 and the crushing assembly 10 on both sides.

[0047] The crushing and returning method of the tea tree branch and leaf pruning and crushing and returning machine has the following specific steps: Step 1: Carry the device to the tea field to be pruned. The walking module 5 at the bottom of the device enters the aisles on both sides of the tea field and drives the device to walk along the tea field.

[0048] Step 2: Start the trimming drive motor 7-1, thereby driving the driving gear 7-3 in the trimming and combing gear box 7-2, and the trimming drive gear 7-5 and combing drive gear 7-4 meshing therewith to rotate. The trimming blade 2-2 reciprocates in the horizontal direction under the cooperation of the trimming drive gear 7-5 and the crank slider structure, thereby trimming the tea tree branches on the device's path. At the same time, the combing rotor 3-1 rotates under the cooperation of the combing drive gear 7-4 and the rotating gear. The hook-shaped sorting strip 3-2 on the combing rotor 3-1 hooks the trimmed broken branches and transports them into the crushing and trimming box 6.

[0049] Step three, start the crushing motor 8-1, thereby driving the transmission gear set 8-3 and the power gear set 8-4 on the crushing gear box 8-2 to move. The pressure roller 9-1 rotates under the drive of the first driving gear located at the top of the power gear set 8-4, combs and compresses the broken branches entering the crushing pruning box 6, and gradually transports them to the crushing chamber. At the same time, the crushing hob 10-1 rotates under the drive of the first driving gear located at the bottom of the power gear set 8-4, and the crushing process of the pruned branches is achieved with the cooperation of the hob blade 10-3 and the crushing bottom knife 10-2. The branches crushed by the hob blade 10-3 and the crushing bottom knife 10-2 enter the crushing notch and rotate synchronously with the crushing hob 10-1. When it rotates to one side of the crushing return to the field mouth, under the action of centrifugal force, the crushed branches are thrown to the crushing return to the field mouth, thereby achieving the purpose of crushing and returning to the field.

[0050] Step 4: The walking module 5 drives the device to continue moving forward and repeats steps 2 and 3, thereby completing the pruning, crushing and returning operations of the tea tree branches in the entire tea field.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
