Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a blade mounting mechanism for a tea garden tea tree pruning machine. Background Technology

[0002] Tea trees in tea gardens are woody plants belonging to the Camellia genus of the Theaceae family, cultivated artificially for harvesting tea leaves. Pruning and other management practices promote new shoot growth, thus increasing tea yield and quality. When tea trees enter their senescent stage, exhibit excessive vegetative growth affecting yield, or when pruning is necessary to control tree height, promote new shoot growth, rejuvenate, and create a good canopy shape, pruning is required. Pruning tea trees in tea gardens is typically done mechanized by pruning machines. The reciprocating or rotating motion of the pruning blades efficiently completes the pruning of branches and leaves, achieving the goals of controlling tree height, rejuvenating, and improving tea yield and quality. Before pruning, the blades must first be installed. This is usually done by unscrewing the bolts one by one to open the pruning machine's flip cover. However, this method of unscrewing the bolts one by one to open the flip cover for blade installation has drawbacks such as low installation efficiency, reliance on tools, easy wear and tear on parts, high labor intensity, and poor installation accuracy.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1

[0030] Reference Figures 1-6 This is the first embodiment of the present utility model. This embodiment provides a blade installation mechanism for a tea garden tea tree pruning machine. The blade installation mechanism for a tea garden tea tree pruning machine includes a main body component 100 and an installation component 200. The two work together to quickly open the flip cover through a buckle, and automatically lock during the blade operation to enhance the buckle fixing effect.

[0031] The main component 100 includes a trimmer 101, a blade 102 is provided on the inner wall of the trimmer 101, a gear 103 is provided at the bottom of the blade 102, and a flip cover 104 is hinged to the top of the trimmer 101.

[0032] The blade 102 and the gear 103 on the inner wall of the trimmer 101 are usually connected by a key or fixed on the drive shaft by a bushing. The gear 103 transmits power through meshing, driving the linkage mechanism of the blade 102 to reciprocate or directly driving the blade 102 to rotate for use.

[0033] The trimmer 101 is a gardening or agricultural tool that uses power-driven blades to trim plants such as lawns, shrubs, and trees to achieve purposes such as shaping and promoting growth. The blade head 102 is the core component of the trimmer 101 and other tools that directly performs the cutting action. It cuts plant branches and leaves through high-speed rotation or reciprocating motion to achieve functions such as trimming and cleaning. In the trimmer 101, the gear 103 transmits power through meshing, realizing the adjustment of the speed and torque of the blade head 102 and the change of the direction of movement, so as to drive the blade to complete the trimming work efficiently. The flip cover 104 is used to protect the internal components of the trimmer 101.

[0034] The mounting component 200 is located at one end of the flip cover 104 and includes a mounting piece 201. The mounting piece 201 includes a fixing frame 2011. The inner wall of the fixing frame 2011 has a slot 2011-1. The other end of the fixing frame 2011 is fixed to one end of the trimmer 101. The inner wall of the slot 2011-1 is provided with a locking rod 2012. A support ring 2013 is sleeved on the outer side of the locking rod 2012. A support plate 2014 is fixed to one end of the support ring 2013. The other end of the support plate 2014 is fixed to one end of the flip cover 104.

[0035] The fixing frame 2011 is used to support the locking rod 2012, the support ring 2013 is used to support the locking rod 2012, and the support plate 2014 is used to support the support ring 2013.

[0036] When it is necessary to close the flip cover 104 and the trimmer 101, the locking rod 2012 is moved. The locking rod 2012 moves to the inner wall of the support ring 2013, and then the flip cover 104 is moved to fit against the surface of the trimmer 101. Then the locking rod 2012 is released, so that the locking rod 2012 engages with the slot 2011-1, thereby closing the flip cover 104 and the trimmer 101.

[0037] Example 2

[0038] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, the installation component 200 includes a fastener 202, which includes a retaining ring 2021. The retaining ring 2021 is sleeved on the outside of the locking rod 2012, and a retaining rod 2022 is fixed to the top of the retaining ring 2021.

[0040] By moving the locking rod 2012, the locking rod 2012 moves the fixing ring 2021, and the movement of the fixing ring 2021 moves the fixing rod 2022.

[0041] Specifically, a support groove 2014-1 is provided on the inner wall of the support plate 2014, and the fixing rod 2022 slides on the inner wall of the support groove 2014-1.

[0042] The movement of the fixed ring 2021 will drive the fixed rod 2022 to move. When the fixed rod 2022 moves, it will slide on the inner wall of the support groove 2014-1. The arrangement of the fixed rod 2022 and the support groove 2014-1 can make the locking rod 2012 move more smoothly and stably.

[0043] Specifically, a spring 2023 is sleeved on the outside of the locking rod 2012. One end of the spring 2023 is fixed to one end of the fixing ring 2021, and the other end is fixed to one end of the support ring 2013. A protective ring 2024 is fixed to one end of the locking rod 2012.

[0044] The protective ring 2024 is used to protect the locking rod 2012 and prevent the locking rod 2012 from falling off during movement.

[0045] By moving the locking rod 2012, the locking rod 2012 moves the fixing ring 2021. The movement of the fixing ring 2021 applies pressure to the spring 2023, and then the flip cover 104 is moved to fit against the surface of the trimmer 101. Then the locking rod 2012 is released. At this time, the spring 2023 rebounds and drives the locking rod 2012 to engage with the slot 2011-1, thereby completing the closure of the flip cover 104 and the trimmer 101.

[0046] Specifically, the mounting assembly 200 also includes an extrusion member 203, which includes an extrusion rod 2031, one end of which is hinged to a support block 2032.

[0047] A fixed shaft is hinged to one end of the extrusion rod 2031 to support the extrusion rod 2031. A protective frame is fitted on the outside of the extrusion rod 2031 to protect it. The other end is fixed to the surface of the flip cover 104.

[0048] After the flip cover 104 and the trimmer 101 are closed, to prevent the locking rod 2012 and the slot 2011-1 from falling off due to vibration or other factors, the centrifugal force generated by the rotation speed of the gear 103 can move the support block 2032. The movement of the support block 2032 will drive the pressing rod 2031 to move. The movement of the pressing rod 2031 will press the locking rod 2012, so that the locking rod 2012 and the slot 2011-1 are firmly locked together, thereby preventing the locking rod 2012 from falling off.

[0049] Example 3

[0050] Reference Figure 5 and Figure 6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0051] Specifically, a connecting rod 2033 is fixed to one end of the support block 2032, and a support frame 2034 is hinged to one end of the connecting rod 2033.

[0052] The other end of the support frame 2034 is fixed to the top of the flip cover 104 to support the connecting rod 2033. Moving the connecting rod 2033 will drive the support block 2032 to move.

[0053] Specifically, a movable ring 2035 is provided on the inner wall of the connecting rod 2033, and a drive shaft 2036 is inserted into the inner wall of the movable ring 2035. The other end of the drive shaft 2036 is inserted into the inner wall of the gear 103 for rotation.

[0054] A splined shaft is fixed at the bottom of the drive shaft 2036, and a bushing corresponding to the splined shaft is inserted into the inner wall of the gear 103. By inserting the splined shaft at the bottom of the drive shaft 2036 into the bushing, the rotation of the gear 103 can drive the splined shaft to rotate, and the splined shaft drives the drive shaft 2036 to rotate.

[0055] The connecting rod 2033 is movably connected to the moving ring 2035.

[0056] After the trimmer 101 is started, the gear 103 rotates. The rotation of the gear 103 drives the bushing to rotate, which in turn drives the spline shaft to rotate. The spline shaft drives the drive shaft 2036 to rotate, which in turn drives the moving ring 2035 to rotate. At this time, the continuous rotation of the gear 103 generates centrifugal force, which causes the moving ring 2035 to move on the drive shaft 2036. The movement of the moving ring 2035 drives the connecting rod 2033 to move, which in turn drives the support block 2032 to move.

[0057] Specifically, drive rods 2037 are fixed at both ends of the movable ring 2035.

[0058] Centrifugal force will move the drive rod 2037, and the movement of the drive rod 2037 will cause the moving ring 2035 to slide on the outside of the drive shaft 2036.

[0059] Specifically, a positioning rod 2038 is fixed to the inner wall of the drive shaft 2036.

[0060] The positioning rod 2038 is used to support the movable rod 2039. By rotating the drive shaft 2036, the drive shaft 2036 rotates, which in turn drives the positioning rod 2038 to rotate. The rotation of the positioning rod 2038 can move the positioning rod 2038.

[0061] Specifically, each of the positioning rods 2038 has a movable rod 2039 hinged to one end.

[0062] A centrifugal ball is fixed at one end of the movable rod 2039. The centrifugal ball generates an outward centrifugal effect due to inertia during the movement. The faster the rotation speed, the easier it is for the radius of the circular motion to increase.

[0063] The rotation of gear 103 drives the bushing to rotate, which in turn drives the spline shaft to rotate. The spline shaft then drives the drive shaft 2036 to rotate, which in turn drives the positioning rod 2038 to rotate. At this time, the rotation of gear 103 generates centrifugal force, which causes the movable rod 2039 to move continuously. The movement of the movable rod 2039 compresses the drive rod 2037. The movement of the drive rod 2037 causes the moving ring 2035 to slide outside the drive shaft 2036. The movement of the moving ring 2035 compresses the connecting rod 2033, causing it to move. The movement of the connecting rod 2033 causes the support block 2032 to move. The movement of the support block 2032 causes the pressing rod 2031 to move. The movement of the pressing rod 2031 compresses the locking rod 2012, making the locking rod 2012 firmly engaged with the slot 2011-1, thus preventing the locking rod 2012 from falling off.

[0064] In use, when it is necessary to close the flip cover 104 and the trimmer 101, the locking rod 2012 is moved. The movement of the locking rod 2012 causes the fixing ring 2021 to move. The movement of the fixing ring 2021 applies pressure to the spring 2023. The movement of the fixing ring 2021 causes the fixing rod 2022 to slide on the inner wall of the support groove 2014-1. Then, by moving the flip cover 104 to fit against the surface of the trimmer 101, the locking rod 2012 is released. At this time, the spring 2023 rebounds and drives the locking rod 2012 to engage with the slot 2011-1, thereby completing the closure of the flip cover 104 and the trimmer 101.

[0065] When it is necessary to further secure the locking rod 2012 and the locking slot 2011-1 to firmly engage the flip cover 104 with the trimmer 101, the trimmer 101 is started. The gear 103 rotates, which in turn drives the bushing to rotate. The bushing rotates, which in turn drives the splined shaft to rotate. The splined shaft then drives the drive shaft 2036 to rotate, which in turn drives the positioning rod 2038 to rotate. The rotation of the gear 103 generates centrifugal force, which causes the movable rod 2039 to move continuously. The movable rod 2039 moves to the position corresponding to the drive... The rod 2037 is pressed, and the movement of the driving rod 2037 will cause the moving ring 2035 to slide outside the driving shaft 2036. The movement of the moving ring 2035 will press the connecting rod 2033, causing the connecting rod 2033 to move. The movement of the connecting rod 2033 will cause the support block 2032 to move. The movement of the support block 2032 will cause the pressing rod 2031 to move. The movement of the pressing rod 2031 will press the locking rod 2012, so that the locking rod 2012 is firmly locked with the slot 2011-1, thereby preventing the locking rod 2012 from falling off.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
