[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 7 .

[0023] Embodiment 1: A tea picking machine with a net covering device comprises a connecting frame 1 connected to a frame of the tea picking machine and arranged at the rear end of the frame in the direction of travel, and a net covering assembly arranged on the connecting frame 1. The Chinese patent with patent number CN119586430A discloses a negative pressure tea picking machine and a tea picking method, which comprises a frame. The connecting frame 1 described in this embodiment is arranged at the rear end of the frame in the direction of travel, that is, when the frame is moving, the tea picking machine operates to shear the tea leaves, and the net covering assembly arranged on the rear end connecting frame 1 covers the surface of the sheared tea trees with a sunshade net.

[0024] The net covering assembly includes a drum 101, a sunshade net 102 and a plurality of support rod groups 2 movably and symmetrically arranged on both sides of a connecting frame 1. Specifically, the sunshade net 102 is rolled up on the drum 101, and the drum 101 is connected to a driving mechanism so that the drum 101 can evenly deliver the sunshade net 102 from the drum 101 after rotation; the connecting frame 1 includes a second guide frame 106 fixed thereto and a first guide frame 103 lifted and arranged above the second guide frame 106, and the support rod group 2 is slidingly arranged on the first guide frame 103 and the second guide frame 106. Figure 1 and Figure 2 As shown, the support rod groups 2 are arranged in an equidistant array.

[0025] The sunshade net 102 extends to one end away from the connecting frame 1 and its two sides are arranged to cover the upper surface of the support rod group 2 near the support rod group 2. The support rod group 2 includes an upper rod body 201 and a lower rod body 202. A magnetic block 207 is fixed to the upper end of the upper rod body 201. The outer diameter of the magnetic block 207 is larger than the outer diameter of the upper rod body 201. The first guide frame 103 is provided with a first guide groove 105 that matches the upper rod body 201. 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.

[0026] The first guide groove 105 is provided with a guide hole 104 at one end away from the connecting frame 1, and the guide hole 104 is connected to the first guide groove 105. Figure 4 As shown, the outer diameter of the guide hole 104 is larger than the outer diameter of the magnetic block 207 . When the upper rod 201 slides along the first guide groove 105 to the guide hole 104 , the upper rod 201 is freed from the restriction with the first guide frame 103 and can slide vertically downward along the guide hole 104 .

[0027] The first guide frame 103 is provided with a stamping assembly 3 which is coaxially arranged with the guide hole 104. Specifically, the stamping assembly 3 is arranged above the guide hole 104, and includes a stamping push rod 301 and a stamping block 302 arranged at the end of the stamping push rod 301. The stamping block 302 is made of hard rubber. The stamping push rod 301 can adopt a pneumatic, electric or hydraulic push rod. When the stamping push rod 301 is driven, the stamping block 302 can vertically stamp downward the adsorption block 402 on the upper rod body 201.

[0028] In order 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 is provided on the first guide frame 103 to cooperate with the upper rod body 201 on the support rod group 2 to fix the side of the sunshade net 102, and the fastening assembly 4 includes a first push rod 401 and an adsorption block 402 provided at the pushing end of the first push rod 401. Figure 3 and Figure 6 As shown, the first guide frame 103 is provided with a vertical downward accommodating tube 403 on the side of the stamping push rod 301 away from the sunshade net 102, and the adsorption blocks 402 are stacked in the accommodating tube 403. A slide 404 cooperating with the accommodating tube 403 is provided on the upper end surface of the first guide frame 103, and the adsorption block 402 at the lower end of the accommodating tube 403 is in contact with and abuts against the slide 404, and at least a distance equal to the thickness of an adsorption block 402 is provided between the accommodating tube 403 and the upper end surface of the slide 404.

[0029] The first push rod 401 is horizontally arranged on the side of the slide 404 away from the sunshade net 102. After the first push rod 401 is started, the adsorption block 402 at the lowest end is pushed toward the side of the sunshade net 102 to the top of the support rod group 2, so that the adsorption block 402 is adsorbed with the magnetic block 207 at the upper end of the upper rod body 201 to achieve clamping of the side of the sunshade net 102, and then the stamping assembly 3 stamps the support rod group 2 downward into the soil to achieve fixation of the support rod group 2 and the sunshade net 102 in the soil.

[0030] In order to achieve the adjustable length of the support rod group 2 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, the lower rod body 202 and the upper rod body 201 are both round 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; the upper end of the lower rod body 202 is rotatably provided with a locking pin 203, and the outer wall of the upper rod body 201 is penetrated with a toothed groove 204 arranged along the axis direction of the rod body and matched with the locking pin 203. Figure 5 and Figure 7 As shown, teeth are arranged on both sides of the toothed groove 204 , and after the locking pin 203 is rotatably arranged on the lower rod body 202 , both ends of the locking pin 203 are placed in the toothed groove 204 and partially slide through the toothed groove 204 .

[0031] The two ends of the locking pin 203 are provided with latch teeth 205 that match the tooth-shaped groove 204. The latch teeth 205 are symmetrically arranged on both sides of the locking pin 203. When the line between the latch teeth 205 on both sides 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; when the locking pin 203 rotates a certain angle, the latch teeth 205 on both sides are aligned with the tooth-shaped grooves 204 on both sides after rotation. The locking pin 203 is locked on the toothed 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 in 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 subjected to the elastic force of the elastic member, the locking pin 203 is in a locked state with the toothed groove 204.

[0032] The connecting frame 1 is fixed with a second guide frame 106 that matches the lower rod body 202. The first guide frame 103 is arranged in parallel with the second guide frame 106, and the first guide frame 103 is lifted and lowered on the second guide frame 106. Figure 4 As shown, the second guide frame 106 is provided with a second push rod 107 connected to the first guide frame 103, and the first guide frame 103 is provided with a plurality of sliding rods 108 that slidably cooperate with the second guide frame 106. The upper ends of the sliding rods 108 are fixed to the lower end surface of the first guide frame 103, and the lower ends are vertically downwardly penetrated through the second guide frame 106 to achieve 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 by the second push rod 107.

[0033] The second guide frame 106 is horizontally provided with a second guide groove 109 which matches with the locking pin 203. Figure 2 As shown, an open notch 110 for the locking pin 203 to disengage is provided at a position corresponding to the second guide groove 109 and the guide hole 104 . The open notch 110 is vertically arranged downward and communicates with the second guide groove 109 .

[0034] The locking pin 203 is provided with a guide surface 206 that is in sliding cooperation with the groove surface of the second guide groove 109, and the locking tooth 205 is arranged perpendicular to the guide surface 206, that is, the lower rod body 202 slides on the second guide frame 106 through the guide surface 206 of the locking pin 203. At this time, the connecting line between the locking teeth 205 on both sides is in a direction parallel to the axis of the lower rod body 202, that is, it is in a disengaged state with the toothed groove 204. At this time, the first guide frame 103 is pushed up and down by the second push rod 107 to realize the extension and contraction of the lower rod body 202 relative to the upper rod body 201; when the support rod group 2 slides to the guide hole 104, the locking pin 203 slides to the open notch 110, and at this time, the locking pin 203 rotates under the elastic force of the elastic member, so that the locking tooth 205 is locked with the toothed groove 204, so that the upper rod body 201 and the lower rod body 202 are locked, and then the support rod group 2 is inserted into the soil as a whole through the stamping assembly 3.

[0035] The connecting frame 1 is provided with a third push rod 5 for driving the support rod group 2 to move. After the third push rod 5 is driven, the support rod group 2 can be moved to the position of a rod group. That is, initially, after a number of support rod groups 2 are placed in equidistant contact, the third push rod 5 is used to push the support rod groups 2 one by one into the guide hole 104 to complete the insertion.

[0036] A tea picking process of a tea picking machine with a net covering device, the process is as follows: S1: When the tea picking machine is picking, the net covering assembly on the connecting frame 1 at the rear end of the frame in the direction of travel covers the surface of the picked tea tree with a net, and the end of the sunshade net is first fixed to the starting end of the tea tree. Initially, the length of the support rod group 2 can be adjusted to adapt to the height of the tea tree by manually adjusting the lifting distance of the second push rod 107; S2: After the tea picking machine travels a certain distance, the two sides of the sunshade net 102 are fixed so that the sunshade net has a certain gap distance relative to the surface of the tea tree. When the sunshade net 102 is fixed, the third push rod 5 pushes the support rod group 2 at the end into the guide hole 104. At this time, the locking pin 203 is placed in the open notch 110, and it is quickly rotated by the elastic force of the elastic member to make the locking tooth 205 and the tooth-shaped groove 204 locked, so that the lower rod body 202 and the upper rod body 201 are relatively fixed, and then the first push rod 401 pushes the adsorption block 402 to the upper end of the support rod group 2 and adsorbs it to 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; S3: After the stamping assembly 3 punches the adsorption block 402 through the stamping block 302, the support rod group 2 is inserted into the soil through the guide hole 104 to fix the two 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 a ventilation effect.

[0037] In this embodiment, the first push rod 401, the second push rod 107, the third push rod 5 and the punching push rod 301 can use push rods with the same power source, that is, pneumatic, electric or hydraulic push rods, and the above push rods are all connected to the controller of the tea picking machine for manual operation and automatic programming control.

[0038] Embodiment 2: This embodiment is a further improvement on the basis of Embodiment 1. A detection component is arranged on the first guide frame 106 to detect the insertion status of the support rod group 2 in the soil. Specifically, the detection component includes a detection switch 6 and a marking member 7. The detection switch 6 is arranged below the guide hole 104 of the first guide frame 106 and on one side of the guide hole 104. When the support rod group 2 is punched into place by the stamping component 3, the magnetic 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 arranged on the controller. When the detection switch 6 does not detect a signal within 1-5s after the stamping component 3 punches the support rod group 2, it means that the surface support rod group 2 has not been inserted to the specified depth of the soil. At this time, the firmness of the support rod group 2 inserted into the soil needs to be further confirmed.

[0039] In order 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 part 7 through a controller. The marking part 7 can adopt a spray tube, which is connected to a spray pump. The spray tube can spray colored liquid through the spray pump. After the detection switch 6 fails to detect a signal, the controller controls the marking part 7 to spray the colored liquid onto the surface of the upper rod body 201 to achieve marking, which is convenient for further manual inspection and confirmation.

[0040] In this embodiment, the marking member 7 can be located at a 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 when used next time.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
