A connecting block 918 is fixedly connected to the upper end of the slider 93, and a limit block 919 is movably inserted at the end of the connecting block 918 close to the turntable 8, and a spring three 920 is fixedly connected to the end of the limit block 919 located in the connecting block 918. A limit groove 921 is provided at the end of the turntable 8 close to the connecting block 918, and the limit block 919 is movably arranged in the limit groove 921. The upper and lower ends of the outer sleeve 91 are respectively fixedly connected to an outer ring plate three 913 and an outer ring plate one 911, and two outer ring plates one 911 on the lower side are provided, and an outer ring plate two 912 is fixedly connected between the two outer ring plates one 911 in the outer sleeve 91, and the upper and lower ends of the inner sleeve 98 are respectively fixedly connected to an inner ring plate one 99 and an inner ring plate two 910.

[0046] The lower side of the insert block 94 is fixed with two guide blocks 916 in the slider 93. The slider 93 is provided with a signal device 917. When the two insert blocks 94 are connected, the signal device 917 can send a signal to make the electric push rod 2 reciprocate one round trip.

[0047] The connecting cavity 92 is fixedly connected to the inner ring 98 and the outer ring 91 .

[0048] The thicknesses of the outer ring plate 2 912 , the outer ring plate 1 911 and the outer ring plate 3 913 increase sequentially, and the thickness of the inner ring plate 1 99 is greater than that of the inner ring plate 2 910 .

[0049] Specifically, when the spray rod 7 rotates normally, the inner ring plate 1 99, the inner ring plate 2 910, the outer ring plate 1 911, the outer ring plate 2 912 and the outer ring plate 3 913 are all fixed, and their combination can make the liquid fertilizer be sprayed reasonably, so that more fertilizer is sprayed on the back of the tea leaves, less fertilizer is sprayed on the front of the tea leaves, and too much fertilizer will not be sprayed on the ground, thereby improving the absorption rate of the liquid fertilizer.

[0050] In another embodiment provided by the present invention, the automatic opening and closing mechanism 10 includes a top block 101 fixedly connected to the upper end of the inner cavity of the box body 1, and a lifting rod 102 is provided on the lower side of the top block 101 in the inner ring 98 for sliding up and down. The lower end of the lifting rod 102 abuts against a trapezoidal block 103, and two trapezoidal blocks 103 are provided. The two trapezoidal blocks 103 are horizontally inserted on the side walls of the upper ends of the inner ring 98 and the outer ring 91, respectively. A spring four 104 is fixedly connected between one end of the trapezoidal block 103 located in the inner ring 98 and the inner ring 98, and an inner ring plate one 99 is fixedly connected to one end of the trapezoidal block 103 away from the lifting rod 102, and the inner ring plate one 99 is connected to the inner ring 98, and the outer ring plate three 913 is connected to the outer ring plate one 911.

[0051] Specifically, the ring plate 1 99, the inner ring plate 2 910, the outer ring plate 1 911 and the outer ring plate 3 913 are all squeezed inward, so that the squeezing rod 914 and the plug plate 95 are pressed inward, so that the through hole 96 on the spray rod 7 and the plug plate 95 no longer overlap, preventing the liquid fertilizer from overflowing from the through hole 96 into the inner cavity of the box body 1 when the spray rod 7 is retracted, causing waste.

[0052] In another embodiment provided by the present invention, the anti-pull mechanism 11 includes a special-shaped slip ring 111, and the special-shaped slip ring 111 is fixedly connected to one end of the spray rod 7 that rotates into the inner sleeve ring 98, and the inner ring plate 1 99 and the inner ring plate 2 910 are fixedly connected to one end close to the spray rod 7 with a contact pressure head 112.

[0053] A plurality of contact pressure heads 112 are arranged in a ring shape at equal intervals.

[0054] Specifically, the special-shaped slip ring 111 will drive the spray rod 7 to rotate, and the direction of rotation is opposite to the direction of rotation of the turntable 8, which makes the branches and leaves wrapped around the spray rod 7 loose, preventing the spray rod 7 from pulling the tightly wrapped branches and leaves when it is retracted, thereby preventing excessive damage to the tea leaves.

[0055] Working principle: When in use, insert the spray rod 7 into the tea leaves, turn on the liquid pump 3 and the motor 5, so that the turntable 8 drives the slider 93 and the spray rod 7 to rotate together, so that the liquid waste sprayed from the through hole 96 can be sprayed in a wider range. When the spray rod 7 rotates, the plug plate 95 will also rotate;

[0056] When the upper part of the plug plate 95 is facing upward, the outer ring plate 3 913 will not squeeze the squeezing rod 914, so that when the upper part of the spraying rod 7 rotates to the upper side, more fertilizer is sprayed out of the upper through hole 96, and more fertilizer is sprayed on the back of the tea leaves;

[0057] When the upper part of the plug plate 95 is facing downward, the outer ring plate 1 911 will squeeze the squeezing rod 914, and the overlapping area of ​​the spraying rod 7 and the through hole 96 on the plug plate 95 will become smaller, so that when the upper part of the spraying rod 7 rotates to the lower side, the through hole 96 on the upper part faces downward, and less fertilizer is sprayed, and less fertilizer is sprayed on the front of the tea leaves;

[0058] When the upper part of the insert plate 95 is completely downward, the outer ring plate 912 will squeeze the squeezing rod 914, and the spraying rod 7 and the through hole 96 on the insert plate 95 have no overlapping area. At this time, the through hole 96 facing downward will not spray fertilizer. Since it needs to be sprayed to the back of the tea leaves at the bottom, this can prevent excess fertilizer from being sprayed on the ground and wasted.

[0059] Similarly, when the lower part of the insert plate 95 rotates, more fertilizer will be sprayed onto the back of the tea leaves;

[0060] When the spray rod 7 is entangled by the tea branches while rotating, if the spray rod 7 continues to rotate, the spray rod 7 and the plug block 94 will be pressed toward the center of the slider 93, so that the plug block 94 touches the two guide blocks 916, thereby connecting the two guide blocks 916, and the signal device 917 sends a signal to make the electric push rod 2 move back and forth, so that the spray rod 7 can be pulled out from the branches and leaves to prevent excessive tea from being pulled off by continuing to rotate, and the limit block 919 disengages from the limit groove 921. When the electric push rod 2 drives the slider 93 to move to When the spray rod 7 is in the inner cavity of the box body 1, the top block 101 will squeeze the lifting rod 102 downward, so that the lifting rod 102 squeezes the two trapezoidal blocks 103 inward, so that the inner ring plate 1 99, the inner ring plate 2 910, the outer ring plate 1 911 and the outer ring plate 3 913 are all squeezed inward, so that the squeezing rod 914 and the plug plate 95 are pressed inward, so that the through hole 96 on the spray rod 7 and the plug plate 95 no longer overlap, preventing the liquid fertilizer from overflowing from the through hole 96 into the inner cavity of the box body 1 when the spray rod 7 is retracted, causing waste;

[0061] When the inner ring plate 1 99 and the inner ring plate 2 910 are pressed inward, the contact pressure head 112 will press the special-shaped slip ring 111. The special-shaped slip ring 111 has a spiral sliding surface at one end facing the contact pressure head 112, so the special-shaped slip ring 111 will drive the spray rod 7 to rotate, and the direction of rotation is opposite to the direction of rotation of the turntable 8. This makes the branches and leaves wrapped around the spray rod 7 loose, preventing the spray rod 7 from pulling the branches and leaves that are too tightly wrapped when it is retracted, thereby preventing excessive damage to the tea leaves.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and the description in the specification are only to illustrate the principles of the present invention.
