Description

Technical Field

[0001] This invention relates to a tea tree pruning machine, and more particularly to a tea tree pruning and crushing machine for returning the pruned tea trees to the field, belonging to the field of agricultural and forestry machinery technology. Background Technology

[0002] Tea tree pruning is divided into five types: shaping pruning, light pruning, deep pruning, heavy pruning, and stump pruning. Shaping pruning is mainly used for young tea trees to cultivate strong main branches; light and deep pruning are mainly used for mature trees to obtain high-yield and high-quality tea; heavy pruning and stump pruning are mainly used for aging tea trees to rejuvenate them. Stump pruning is one of the methods to completely transform the tree canopy. After stump pruning, the newly sprouted shoots emerge from the rootstock, have a shorter physiological age, and produce vigorous branches that can form a neat canopy and a robust tree. With enhanced fertilization and management, tea trees can quickly recover production, achieving the goal of increased yield and improved quality.

[0003] In recent years, the tea-cutting machinery that has emerged is generally a backpack-type garden single-disc saw. During operation, two people are required to assist in carrying the cut tea trees away from the tea garden, making continuous operation impossible, resulting in high labor intensity and low efficiency. Therefore, developing a high-efficiency and practical integrated tea tree cutting, crushing, and returning machine is of significant practical importance.

[0004] Chinese patent application publication number CN 108575386 A discloses a tea tree pruning machine, which includes a frame supported on a tracked chassis. A handrail extends rearward from the frame, and the front end of the frame is hinged to a blade holder via upper and lower swing arms, forming a parallelogram mechanism. The blade holder is equipped with pendant-shaped left and right rotary cutting blade groups driven by a power source. Each rotary cutting blade group has a set of disc cutting blades with a gradually decreasing diameter from top to bottom, and the edges of adjacent cutting blades in the left and right rotary cutting blade groups overlap. However, this structure is not suitable for completely pulverizing and returning the tea leaves to the field.

[0005] Chinese patent application publication number CN 119547658 A discloses an integrated machine for pruning and crushing tea branches and leaves, including a main frame and a crushing and pruning box mounted on top of the main frame. A walking module is installed at the bottom of the main frame for driving the main frame to move between tea fields. The crushing and pruning box has a pruning component, a branch-shaping and transporting component, and a crushing and returning component arranged sequentially on top of the main frame. The pruning component can prune branches on the tea trees while the main frame is moving, and the branch-shaping and transporting component simultaneously transports the pruned branches into the crushing and pruning box. Its structure is suitable for pruning but not for bench cutting. Summary of the Invention

[0006] This invention provides a tracked power integrated machine for pruning, crushing, and uniformly spreading and returning crushed tea trees to the field.

[0007] A tea tree pruning, crushing, and returning-to-field integrated machine includes a tracked power platform, a pruning conveying component, and a crushing and returning-to-field component; The tracked power platform provides power to the reaping and conveying assembly and the crushing and returning-to-field assembly. The table-cutting conveyor assembly includes a cutting device and a conveying device; The cutting device includes a reciprocating cutting blade and a blade guard; the reciprocating cutting blade and the blade guard work together to cut tea trees; The conveying device includes a spiral auger, a casing, and a conveying channel; The tea tree crushing and returning assembly includes a tea tree crushing and returning blade, a second cover, and a tea tree inlet. The tea tree inlet is located at the right end of the second cover and is connected to the conveying channel. The tea tree crushing and returning blade is placed inside the second cover. The lower end of the second cover is provided with a material discharge port.

[0008] Furthermore, the power output shaft of the tracked power platform is connected to the power input shaft of the crushing and returning component via belt drive, and the power input shaft of the crushing and returning component is connected to the drive shaft of the reaping and conveying component via a power flexible shaft. The drive shaft drives the auger, and at the same time drives the eccentric wheel to rotate via belt drive; The eccentric wheel drives the connecting rod to reciprocate, and the reciprocating motion of the connecting rod drives the rocker arm, which in turn drives the cutting blade to reciprocate and cut the tea tree.

[0009] Furthermore, the power transmission system of the aforementioned crushing and returning component is achieved by transmitting power from the power output shaft of the tracked power platform to the transmission shaft of the crushing and returning component via belt drive, thereby driving the crushing and returning cutter to perform its operation.

[0010] Furthermore, the tea tree output port of the aforementioned reaping conveyor assembly is funnel-shaped.

[0011] Furthermore, a folding connection device is provided between the aforementioned reaping conveyor assembly and the crushing and returning-to-field assembly; the folding connection device is hinged to the right side of the reaping conveyor assembly; The folding connection device for the machine includes a hydraulic cylinder mounting base, a hydraulic cylinder mounting lug, a hydraulic cylinder, and an arc-shaped connecting plate; The hydraulic cylinder mounting base is fixedly connected to the axial right side cover of the crushing and returning-to-field assembly. One end of the hydraulic cylinder is connected to the hydraulic cylinder mounting lug fixed on the base by a pin, and the other end is connected to the arc-shaped connecting plate by a pin. The distribution and connection of the reaping conveyor and crushing and returning components are achieved through a folded connection.

[0012] Furthermore, the aforementioned tea tree pulverizing and returning-to-field blades include a blade shaft, a blade disc, and T-shaped blades; the blade shaft is equipped with 3 sets of blade discs; each blade disc is equipped with 3 T-shaped blades; the T-shaped blades are fixedly connected to the blade disc; the blade discs are mounted on the blade shaft through slots; and the blade discs are positioned with each other by bushings.

[0013] Furthermore, the two support wheels are fixedly connected to the bottom of the second cover.

[0014] Beneficial effects: First, by using the tracked power platform of the tea garden management machine as the power source, and adding rear-mounted tea tree cutting tools, tea tree conveying mechanisms, tea tree crushing mechanisms, etc., the integrated operation of tea tree cutting and crushing can be realized.

[0015] Secondly, the tea garden management machine moves between the tea tree rows, and the rear-mounted tea tree cutting tool folds open to the left and right sides. The tea tree crushing mechanism is installed directly behind the tea garden management machine. After the tea tree that is fed in is crushed, it is scattered between the tea garden rows, which not only inhibits the growth of weeds, but also serves as green manure for the growth of tea trees.

[0020] The present invention will be further described below with reference to the accompanying drawings: See Figure 1-4 This invention is an integrated machine for pruning, crushing and returning tea trees to the field. It mainly consists of a tracked self-propelled power platform 1, a tea tree pruning and conveying assembly 2, a machine tool folding and connecting assembly 3, a crushing and returning assembly 4, a power transmission flexible shaft (power for the pruning and conveying assembly) 5, and a machine tool lifting cylinder 6 (power for the tea tree crushing and returning assembly).

[0021] (1) Tracked power platform 1 serves as the power source for the machine's movement and the tea tree reaping and crushing mechanism, providing power input for the operation of implements (such as the reaping conveyor assembly 2 and the crushing and returning assembly 3).

[0022] (2) The tea tree cutting and conveying assembly 2 is located on the right side of the tracked power platform 1 and is hinged to the tracked power platform 1. It includes a tea tree cutting mechanism, a tea tree conveying mechanism, a power transmission system, etc.

[0023] (3) The tea tree reaping conveyor assembly 2 is mainly composed of reciprocating sawtooth cutting blades 2.4, blade protector 2.5, spiral auger 2.3, cover 2.1, square block 2.11, power transmission assembly, etc.

[0024] The reciprocating serrated cutting blade 2.4, together with the blade protector 2.5, works in tandem to achieve the pruning and cutting of tea trees; the reciprocating serrated cutting blade 2.4 is driven by the pull rod 2.7 to move the rocker arm 2.6 back and forth.

[0025] The right axial end of the casing 2.1 has an arc-shaped tea tree outlet 2.12, which facilitates the conveying of the harvested tea tree branches to the crushing and returning-to-the-field assembly for crushing and returning to the field; its right side has an outwardly opening branch-gathering plate 2.2. The power transmission assembly uses the power transmission flexible shaft 5 as the power input, which drives the spiral auger 2.3 on the rotating shaft via the transmission shaft 2.10. The spiral auger 2.3 compresses the harvested tea trees and puts them into the crushing and returning to the field assembly 4.

[0026] The eccentric wheel 2.8 drives the tie rod 2.7 to reciprocate. The reciprocating motion of the tie rod 2.7 drives the rocker arm 2.6, which in turn drives the cutting blade 2.4 to reciprocate and cut the tea pile.

[0027] (4) The tea tree crushing and returning component 4 is mainly composed of a cover 4.1, an axial left side plate 4.2, a tea tree crushing and returning tool 4.3, a square block 4.5, a tracked power platform power output shaft 4.6, a tracked power platform power output shaft bushing 4.7, a mounting base 4.8, a crushing and returning component power input shaft 4.9, a belt drive 4.10, and a support wheel 4.11.

[0028] Cover 2 4.1 has small holes axially opened on its cylindrical surface directly below, so that the crushed tea tree stems and branches can pass through to achieve the purpose of returning them to the field.

[0029] The left axial plate 4.2 is provided with a tea tree output port 2.12 of the same size as the tea tree reaping and conveying assembly 2, and an arc-shaped tea tree input port 4.4.

[0030] The tea tree pulverizer and return-to-field blade 4.3 consists of a cutter shaft 4.3.1, cutter discs 4.3.2, and T-shaped blades 4.3.3. The cutter shaft 4.3.1 has three sets of cutter discs 4.3.2; each cutter disc 4.3.2 has three T-shaped blades 4.3.3. The T-shaped blades 4.3.3 are fixed to the cutter discs; the cutter discs 4.3.2 are mounted on the cutter shaft 4.3.1 via slots; the cutter discs 4.3.1 and 4.3.2 are positioned together by bushings.

[0031] The support wheel 4.11 is fixed directly below the cover 4.1 of the tea tree crushing and returning component. When the tea tree pruning and returning operation is carried out, it provides auxiliary support to the tea tree crushing and returning component 3.

[0032] (5) The power transmission flexible shaft 5 is connected at one end to the crushing blade shaft of the crushing and returning to the field component 4, and at the other end to the spiral auger rotating shaft (transmission shaft 2.10) of the reaping and conveying component 2 to realize power transmission.

[0033] (6) The folding connection device 3 mainly consists of a hydraulic cylinder mounting base 3.1, a hydraulic cylinder mounting ear plate 3.2, a hydraulic cylinder 3.3, an arc-shaped connecting plate 3.4, a pin 3.5, a pin shaft 3.6, and a bushing 3.7. When the machine needs to turn around, the table-harvesting conveyor assembly 2 can be folded outward 180 degrees along the pin shaft 3.6 under the action of the folding connection device 3, making it convenient for the whole machine to move together.

[0034] The hydraulic cylinder mounting base 3.1 is fixedly connected to the right side cover 4.1 of the tea tree crushing and returning component 4.

[0035] One end of the hydraulic cylinder 3.3 is connected to the ear plate 3.2 fixed on the base by a pin, and the other end is connected to the arc-shaped connecting plate 3.4 by a pin.

[0036] The arc-shaped connecting plate 3.4 is divided into two groups, left and right, with two pieces in each group. The left end of the arc-shaped connecting plate is connected to the base fixed to the crushing and returning to the field component 4 via a pin; its right end is connected to the telescopic rod of the hydraulic cylinder 3.3 via a pin. The right end of the arc-shaped connecting plate is connected to the base fixed to the platform conveying component 2 via a wire; its left end is connected to the telescopic rod of the hydraulic cylinder 3.3 via a pin.

[0037] The pin 3.6 and the bushing 3.7 are fitted together to form a set, with upper and lower sets. The pin 3.6 is fixed to the outer edge of the left axial cover 4.1 of the crushing and returning to the field component 4; the bushing 3.7 is fixed to the outer edge of the right axial cover 2.1 of the reaping and conveying component 2.

[0038] The pin 3.6 and the bushing 3.7 are hinged and fixed to the reaping conveyor assembly 2 and the crushing and returning to the field assembly 4 respectively, realizing the folding connection between the reaping conveyor assembly 2 and the crushing and returning to the field assembly 4.

[0039] Specifically, after the tea trees are cut, the branches and leaves enter the casing due to inertia. The tea trees are then crushed and compressed by the auger before entering the conveying channel. After entering the crushing and returning-to-the-field component, the tea trees are crushed again by three crushing rollers. Almost all the crushed tea tree branches and leaves are then sent back to the tea garden through the discharge port. After multiple crushing processes, the tea tree branches and leaves of this invention achieve a crushing length of ≤20 cm for returning to the field; a crushing length qualification rate of ≥95%; and a missed cutting rate of ≤1.5%. By adding uniform crushing rollers and a trumpet-shaped spout, the branches and leaves are evenly scattered in force, direction, and range, covering the entire working width.
