[0001] The present invention relates to the technical field of agricultural machinery, and in particular to a tea picking machine with a net covering device and its tea picking process. Background Art

[0002] A tea picking machine is a modern picking device. The shearing knife cooperates with the traveling mechanism to shear and pick the upper surface of the tea tree, thus greatly improving the picking efficiency. On this basis, some tea picking machines are also equipped with a net covering mechanism to cover the surface of the tea tree with a sunshade net after picking to achieve the effect of shading, and the sunshade net covering is an important agronomic measure to adjust the microenvironment of the tea garden and improve the tea quality. At present, the tea picking machine with a net covering device or the tea tree net covering device still has the following disadvantages and deficiencies:

[0003] The traditional sunshade net covering in tea gardens relies on manual labor or simple machinery, and there are problems such as low efficiency, poor adaptability, and prominent contradictions between ventilation and shading. The manual net covering process is cumbersome. The height of the support rods is fixed, resulting in unreasonable net surface spacing. The close-fitting covering hinders air flow and is prone to diseases, and the step-by-step operation is easy to damage the tea tree.

[0004] However, the current tea picking machines integrated with a net covering device have problems such as structural redundancy, insufficient adjustment accuracy, and difficulty in adapting the net covering height to the terrain and the dynamic shape of the tea tree. Summary of the Invention

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and the specific implementation mode: See Figures 1-7 。

[0040] Embodiment 1: A tea plucking machine with a net covering device, including an adapter frame 1 connected to the tea plucking machine frame body and provided at the rear end in the advancing direction of the frame body, and a net covering component provided on the adapter frame 1. The Chinese patent with the patent number CN119586430A discloses a negative pressure tea plucking machine and a tea plucking method, which includes a frame body. In this embodiment, the adapter frame 1 is provided at the rear end in the advancing direction of its frame body, that is, when the frame body advances, the tea plucking machine operates to shear the tea leaves, and the net covering component provided on the rear adapter frame 1 covers the surface of the tea tree after shearing with a sunshade net.

[0041] The net covering component includes a winding drum 101, a sunshade net 102, and a number of support rod groups 2 symmetrically arranged on both sides of the adapter frame 1. Specifically, the sunshade net 102 is wound on the winding drum 101, and the winding drum 101 is connected with a driving mechanism, so that the winding drum 101 evenly sends out the sunshade net 102 from the winding drum 101 after rotation; the adapter frame 1 includes a second guide frame 106 fixed thereto and a first guide frame 103 arranged above the second guide frame 106 in a lifting manner, and the support rod groups 2 are guided and slidably arranged on the first guide frame 103 and the second guide frame 106, as Figure 1 and Figure 2 shown, the support rod groups 2 are arranged in an equidistant array.

[0042] The sunshade net 102 extends towards the end far from the adapter frame 1, and both sides thereof cover the upper surface of the support rod groups 2 near the support rod groups 2. The support rod groups 2 include an upper rod body 201 and a lower rod body 202. A magnetic block 207 is fixedly arranged at the upper end of the upper rod body 201. The outer diameter of the magnetic attraction block 207 is larger than the outer diameter of the upper rod body 201. A first guide groove 105 matched with the upper rod body 201 is arranged on the first guide frame 103. The upper rod body 201 is guided and slidably arranged in the first guide groove 105, and the magnetic block 207 is placed above the upper surface of the first guide frame 103, that is, the outer diameter of the magnetic block 207 is larger than the groove width of the first guide groove 105.

[0043] A guide hole 104 is arranged at one end of the first guide groove 105 far from the adapter frame 1, and the guide hole 104 is connected to the first guide groove 105 in a through manner, as Figure 4 shown, the outer diameter of the guide hole 104 is larger than the outer diameter of the magnetic block 207. When the upper rod body 201 slides along the first guide groove 105 to the guide hole 104, the upper rod body 201 is released from the restriction of the first guide frame 103 and can slide vertically downward along the guide hole 104.

[0044] A stamping assembly 3 coaxial with the guiding hole 104 is provided on the first guiding frame 103. Specifically, the stamping assembly 3 is arranged above the guiding hole 104 and includes a stamping push rod 301 and a stamping block 302 provided at the end of the stamping push rod 301. The stamping block 302 is made of hard rubber, and the stamping push rod 301 can be a pneumatic, electric or hydraulic push rod. After being driven, the stamping push rod 301 can make the stamping block 302 vertically press down on the adsorption block 402 on the upper rod body 201.

[0045] To fix the sunshade net 102 on the upper end of the upper rod body 1 while the upper rod body 201 is being stamped, a fastening assembly 4 that cooperates with the upper rod body 201 on the support rod group 2 to fix the side edge of the sunshade net 102 is provided on the first guiding frame 103. The fastening assembly 4 includes a first push rod 401 and an adsorption block 402 provided at the advancing end of the first push rod 401. As Figure 3 and Figure 6 shown, a vertically downward receiving tube 403 is provided on the side of the first guiding frame 103 away from the sunshade net 102 where the stamping push rod 301 is located. The adsorption blocks 402 are stacked in the receiving tube 403. A sliding table 404 that cooperates with the receiving tube 403 is provided on the upper end surface of the first guiding frame 103. The lowermost adsorption block 402 in the receiving tube 403 contacts and abuts against the sliding table 404, and there is at least a distance equal to the thickness of one adsorption block 402 between the upper end surface of the receiving tube 403 and the sliding table 404.

[0046] The first push rod 401 is horizontally arranged on the side of the sliding table 404 away from the sunshade net 102. After the first push rod 401 is activated, the lowermost adsorption block 402 is pushed towards the sunshade net 102 side above the support rod group 2, so that the adsorption block 402 adsorbs to the magnetic block 207 at the upper end of the upper rod body 201 to realize the clamping of the side edge of the sunshade net 102. Subsequently, the stamping assembly 3 stamps the support rod group 2 into the soil downward to realize the fixation of the support rod group 2 and the sunshade net 102 in the soil after fixation.

[0047] To enable the length of the support rod group 2 to be adjustable to adapt to different tea tree heights, in this embodiment, the lower rod body 202 is telescopically arranged at the lower end of the upper rod body 201. Specifically, both the lower rod body 202 and the upper rod body 201 are circular tubes, and the outer diameter of the lower rod body 202 is smaller than the inner hole of the upper rod body 201, so that the lower rod body 202 is inserted into the inner hole of the upper rod body 201; a locking pin 203 is rotatably arranged at the upper end of the lower rod body 202, and a tooth-shaped groove 204 arranged along the axis of the rod body and cooperating with the locking pin 203 is provided through the outer wall of the upper rod body 201. As Figure 5 and Figure 7 shown, teeth are provided on both sides of the tooth-shaped groove 204. After the locking pin 203 is rotatably arranged on the lower rod body 202, both ends of it are slidably arranged through the tooth-shaped groove 204 when placed inside the tooth-shaped groove 204.

[0048] Both ends of the locking pin 203 are provided with engaging teeth 205 that cooperate with the tooth-shaped groove 204. The engaging teeth 205 are symmetrically arranged on both sides of the locking pin 203. When the line connecting the two engaging teeth 205 is parallel to the direction of the tooth-shaped groove 204, the locking pin 203 can slide vertically along the tooth-shaped groove 204, that is, the lower rod body 202 can slide vertically relative to the upper rod body 201. After the locking pin 203 rotates a certain angle, the engaging teeth 205 on both sides are engaged with the tooth shapes on the tooth-shaped grooves 204 on both sides after rotation, so that the locking pin 203 is locked on the tooth-shaped groove 204. At this time, the lower rod body 202 and the upper rod body 201 are in a relatively fixed state. An elastic member is provided between the locking pin 203 and the lower rod body 202. Preferably, the elastic member is a torsion spring, which is sleeved on the middle position of the locking pin 203 and placed in the inner hole of the lower rod body 202 to realize the rotational reset of the locking pin 203. When the locking pin 203 is not affected by the elastic force of the elastic member, the locking pin 203 is in a locked state with the tooth-shaped groove 204.

[0049] A second guide frame 106 that cooperates with the lower rod body 202 is fixedly provided on the connecting frame 1. The first guide frame 103 is arranged parallel to the second guide frame 106, and the first guide frame 103 is vertically lifted and lowered on the second guide frame 106. As Figure 4 shown, a second push rod 107 connected to the first guide frame 103 is provided on the second guide frame 106. A plurality of sliding rods 108 that are slidably matched with the second guide frame 106 are provided on the first guide frame 103. The upper ends of the sliding rods 108 are fixedly arranged on the lower end surface of the first guide frame 103, and the lower ends vertically penetrate through the second guide frame 106 to realize the vertical sliding of the first guide frame 103 relative to the second guide frame 106, and the distance between the two guide frames is adjusted through the second push rod 107.

[0050] A second guide groove 109 that cooperates with the locking pin 203 is horizontally provided on the second guide frame 106. As Figure 2 shown, an open slot 110 for the locking pin 203 to disengage is provided at the corresponding position of the second guide groove 109 and the guide hole 104. The open slot 110 is vertically downward and communicates with the second guide groove 109.

[0051] The locking pin 203 is provided with a guiding surface 206 that fits and slides in cooperation with the surface of the second guiding groove 109. The locking teeth 205 are arranged perpendicular to the guiding surface 206. That is, the lower rod body 202 slides on the second guiding frame 106 through the guiding surface 206 of the locking pin 203. At this time, the connection line between the two sides of the locking teeth 205 is in a direction parallel to the axis of the lower rod body 202, that is, in a disengaged state from the tooth-shaped groove 204. At this time, after the first guiding frame 103 is pushed up and down by the second push rod 107, the telescopic movement of the lower rod body 202 relative to the upper rod body 201 is realized; when the support rod group 2 slides to the guiding hole 104, the locking pin 203 slides to the open notch 110. At this time, the locking pin 203 rotates under the elastic force of the elastic member, so that the locking teeth 205 are locked with the tooth-shaped groove 204, thereby locking the upper rod body 201 and the lower rod body 202. Subsequently, the support rod group 2 is integrally inserted into the soil by the stamping assembly 3.

[0052] The connecting frame 1 is provided with a third push rod 5 for driving the displacement of the support rod group 2. After being driven, the third push rod 5 can move the support rod group 2 by the position of one rod group. That is, initially, after a number of support rod groups 2 are placed in contact at equal intervals, the support rod group 2 is pushed into the guiding hole 104 one by one through the third push rod 5 to complete the insertion.

[0053] The tea picking process of a tea picking machine with a net covering device is as follows:

[0054] S1: When the tea picking machine is picking tea, the net covering assembly on the connecting frame 1 at the rear end of the traveling direction of the frame body covers the surface of the tea tree after picking. The end of the sunshade net is first fixed at the starting end of the tea tree. Initially, the lifting distance of the second push rod 107 can be adjusted manually to adjust the length of the support rod group 2 to adapt to the height of the tea tree.

[0055] S2: After the tea picking machine travels a certain distance, both sides of the sunshade net 102 are fixed so that there is a certain gap distance between the sunshade net and the surface of the tea tree. When fixing the sunshade net 102, the third push rod 5 pushes the support rod group 2 at the end into the guiding hole 104. At this time, the locking pin 203 is placed in the open notch 110, and it quickly rotates under the elastic force of the elastic member to make the locking teeth 205 engage with the tooth-shaped groove 204, so that the lower rod body 202 and the upper rod body 201 are relatively fixed. Subsequently, the first push rod 401 pushes the adsorption block 402 to the upper end of the support rod group 2 to adsorb with the magnetic adsorption block 207 of the support rod group 2, and the side of the sunshade net 102 located on the surface of the support rod group 2 is clamped.

[0056] S3: The stamping assembly 3 punches the adsorption block 402 so that the support rod group 2 penetrates into the soil through the guiding hole 104 to realize the fixation of both sides of the sunshade net 102 relative to the surface of the tea tree, and according to the height of the support rod group 2, a certain gap is left between the surface of the sunshade net 102 and the surface of the tea tree to achieve the ventilation effect.

[0057] In this embodiment, the first push rod 401, the second push rod 107, the third push rod 5, and the stamping push rod 301 can be push rods with the same power source, that is, pneumatic, electric, or hydraulic push rods can be used, and the above-mentioned push rods are all connected to the controller of the tea picking machine to facilitate manual operation and automated programming control.

[0058] Embodiment 2: This embodiment is a further improvement based on Embodiment 1. A detection component is provided on the first guide frame 106 to detect the insertion state of the support rod group 2 into the soil. Specifically, the detection component includes a detection switch 6 and a marking member 7. The detection switch 6 is arranged below and on one side of the guide hole 104 of the first guide frame 106. When the support rod group 2 is in place after being stamped by the stamping component 3, the magnetic attraction block 207 is detected by the detection switch 6. The detection switch 6 can be a distance switch or a contact switch. The detection switch 6 is connected to a controller, and a delay switch is provided on the controller. When the stamping component 3 stamps the support rod group 2, if the detection switch 6 does not detect a signal within 1 - 5 s, it means that the support rod group 2 has not been inserted to the specified depth in the soil, and at this time, the firmness of the support rod group 2 inserted into the soil needs to be further confirmed.

[0059] To mark the support rod group 2 when it is not inserted into the soil or not fully inserted into the soil, the detection switch 6 is connected to the marking member 7 through the controller. The marking member 7 can be a spray pipe, which is connected to a spray pump. The spray pipe can spray colored liquid through the spray pump. After the detection switch 6 does not detect a signal, the controller controls the marking member 7 to spray colored liquid and spray it on the surface of the upper rod body 201 to achieve marking, which is convenient for manual follow-up inspection and confirmation.

[0060] In this embodiment, the marking member 7 can be located at a certain distance below the detection switch 6 to achieve spraying on the surface of the upper rod body 201, and the colored liquid can be a washable paint, which is convenient for removing the paint during the next use.

[0061] 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 foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
