Description
Technical Field
[0001] The invention relates to the technical field of spraying pest control for jujube trees, and in particular to a pest control device for jujube tree planting and a pest control method thereof. Background Art
[0002] As a common fruit tree, jujube trees may encounter threats from various pests during their growth process. These pests will not only affect the healthy growth of jujube, but may also lead to a decrease in yield and reduced fruit quality. Common jujube pests include the jujube leopard borer, which is mainly distributed in Hebei, Henan, Shandong, Shaanxi and other places. This pest mainly harms walnut and jujube trees, followed by apple, apricot, pear, pomegranate, thorn, etc. It seriously harms the jujube head, preventing the jujube tree crown from expanding and affecting the yield of the jujube tree. Another example is the jujube flying elephant. The adult of the jujube flying elephant feeds on buds and leaves, often eating up the tender buds of the jujube tree, weakening the tree, delaying fertility, and reducing yield and quality. Its larvae live in the soil and harm the underground tissues of the plant. Prevention and control methods include spraying the trunk and the ground near the base of the trunk with drugs, or sprinkling powder within 60 to 90 cm of the base of the trunk to poison the insects. For the pest control of jujube trees, comprehensive measures should be taken, including drug control, agricultural control and biological control, so as to effectively control the number of pests and ensure the healthy growth, high yield and high quality of jujube trees. However, in the process of prevention and control, since jujube trees are usually planted on a large scale, and in order to ensure the effect of spraying to prevent pests, spraying is usually required every ten days, and more than three times in a row can achieve better prevention and control effects. Therefore, the traditional manual spraying method is inefficient and cannot meet the pest control requirements of large-scale planting. The spraying method using large agricultural machinery is not suitable for jujube trees. Large agricultural machinery cannot carry out all-round and uniform application of pesticides to the trunk of the jujube tree and the soil part of the ground, and there are certain dead corners for prevention and control. Therefore, a pest control device for jujube tree planting and a control method thereof are proposed. Summary of the invention

DETAILED DESCRIPTION
[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0044] See also Figure 1-10 The present invention provides a technical solution: a device for controlling pests and diseases for jujube tree planting. Embodiment 1
[0045] The present embodiment discloses: a fixed ring 1, a functional ring 2 is installed on the upper surface of the fixed ring 1, the fixed ring 1 and the functional ring 2 are both semicircular ring designs, the two fixed rings 1 are rotatably connected, the two functional rings 2 are rotatably connected, and the lower end of the functional ring 2 is a T-shaped design, and the functional ring 2 is rotatably connected to the fixed ring 1 through the T-shaped design at the lower end, and the upper end outer edge of the functional ring 2 is evenly fixed with tooth blocks on the lower surface, and the side surface of the fixed ring 1 is provided with a displacement spraying mechanism, and the ground and roots around the jujube tree are comprehensively prevented and controlled by spraying in motion;
[0046] The displacement spraying mechanism comprises: an inner support ring 3, the inner support ring 3 is arranged on the inner surface of the fixed ring 1, and a support rod 4 is fixedly arranged on the side surface of the inner support ring 3, a transmission gear 5 is rotatably installed on the outer surface of the fixed ring 1, and a driving motor 6 is fixedly installed inside the side surface of the fixed ring 1, and one end of the output shaft of the driving motor 6 is fixedly connected to the driving gear 7, a displacement motor 15 is fixedly installed inside the side surface of the inner support ring 3, and one end of the output shaft of the displacement motor 15 passes through the outer surface of the inner support ring 3 and is fixedly connected to a displacement wheel 16;
[0047] The inner support ring 3 is of arc-shaped design, one end of the support rod 4 penetrates the outer surface of the fixing ring 1, and the outer surface of one end of the support rod 4 located outside the fixing ring 1 is provided with a thread, and the support rod 4 is slidably connected with the fixing ring 1;
[0048] The transmission gear 5 is threadedly connected to the support rod 4, and the transmission gear 5 facing the driving gear 7 is meshed with the driving gear 7. The transmission gear 5 is meshed with the functional ring 2 through the tooth block on the lower surface of the outer edge of the upper end of the functional ring 2.
[0049] Before use, the fixing ring 1 is rotated to open the two fixing rings 1. After the opened fixing ring 1 is placed on the bottom of the tree trunk, the two fixing rings 1 are rotated so that the two fixing rings 1 form a complete ring. Then the driving motor 6 is started, and the driving motor 6 drives the driving gear 7 to rotate. The driving gear 7 drives the transmission gear 5 to rotate by meshing with the opposite transmission gear 5. The transmission gear 5 drives the functional ring 2 to rotate by meshing with the functional ring 2. At this time, the functional ring 2 rotates relative to the fixing ring 1, so that the functional ring 2 and the opening end of the fixing ring 1 are misaligned. At this time, the functional ring 2 and the fixing ring 1 are locked with each other and cannot be opened by rotation.
[0050] During the rotation of the functional circle 2, the functional circle 2 drives the transmission gear 5 to rotate by meshing with other transmission gears 5. The transmission gear 5 drives the support rod 4 and the inner support ring 3 to slide toward the direction of the trunk through the threaded connection with the support rod 4 until the outer surface of the displacement wheel 16 contacts the surface of the trunk. At this time, the displacement motor 15 is started to drive the displacement wheel 16 to rotate, thereby driving the fixed circle 1 to move upward relative to the trunk. Embodiment 2
[0051] This embodiment is disclosed on the basis of the embodiment 1: the displacement spraying mechanism also includes: a rotation direction gear 8, the rotation direction gear 8 is embedded and rotatably installed inside the middle section of the inner support ring 3, and a sliding rod 9 is slidably installed on the lower end of the rotation direction gear 8, and a spray head 10 is fixedly installed on the lower end of the sliding rod 9, and a rotating contact wheel 11 is installed on the side surfaces of both ends of the spray head 10, a liquid storage chamber 12 is opened inside the fixed ring 1, and a liquid pump 13 is fixedly installed inside the liquid storage chamber 12, a liquid injection port 14 is fixedly installed on the lower surface of the fixed ring 1, and the rotation shaft of the displacement wheel 16 on one side is fixedly connected to the angle gear 17, an electric push rod 18 is fixedly provided on the outer surface of the inner support ring 3, and a contact block 19 is fixedly connected to the end of the electric push rod 18 facing the inner side of the fixed ring 1, and the electric push rod 18 is slidably connected to the fixed ring 1;
[0052] The hand direction gear 8 and the displacement wheel 16 are eccentrically designed, and the hand direction gear 8 is meshed and connected with the angle gear 17, and the angle gear 17 is concentrically arranged with the displacement wheel 16;
[0053] The upper end of the sliding rod 9 is penetrated by one end of the rotating shaft of the rotating direction gear 8, and a spring is connected between the sliding rod 9 and one end of the rotating shaft of the rotating direction gear 8;
[0054] The nozzle 10 is designed in a truncated cone shape with a small top and a large bottom, and the lower end of the contact wheel 11 protrudes from the lower end surface of the nozzle 10;
[0055] The liquid outlet of the liquid pump 13 penetrates the inner surface of the fixing ring 1, and a spiral hose is connected between the liquid outlet of the liquid pump 13 and the nozzle 10, and the upper end of the liquid injection port 14 is connected to the liquid storage chamber 12;
[0056] The liquid storage chamber 12 is filled with the control agent in advance through the liquid injection port 14. During the upward movement of the fixed ring 1, as the displacement wheel 16 on one side rotates, the displacement wheel 16 drives the rotation gear 8 to rotate through the meshing of the angle gear 17 and the rotation gear 8, and the liquid pump 13 inside the liquid storage chamber 12 sprays the agent in the liquid storage chamber 12 through the nozzle 10 through the spiral hose. At this time, the agent is first sprayed onto the ground through the vertically downward nozzle 10 for control, and then the rotation gear 8 drives the nozzle 10 to flip upward through the sliding rod 9. During the upward flipping of the nozzle 10, the root of the trunk and the side surface of the middle section of the trunk are gradually sprayed with the drug for control from top to bottom;
[0057] When the diameter of the tree trunk is large and the spraying range needs to be expanded, the displacement wheel 16 drives the fixing ring 1 to move to the specified position, and then the electric push rod 18 is started to drive the contact block 19 to extend and contact the surface of the tree trunk to support and fix the fixing ring 1, and then the driving motor 6 drives the driving gear 7 to rotate in the opposite direction so that the inner support ring 3 slides in the opposite direction away from the tree trunk. At this time, the displacement motor 15 is started again to drive the displacement wheel 16 to rotate, so that the nozzle 10 can spray and prevent at a position farther away from the tree trunk, so that the medicine can be sprayed to a larger range, ensuring that the surface of the tree trunk can be sprayed to achieve a better prevention and control effect;
[0058] After spraying is completed, the fixed circle 1 is driven down to the ground, and the nozzle 10 is vertically downward and contacts the ground through the contact wheel 11 to stably support the fixed circle 1.

[0061] Step 2. Select the jujube tree that needs to be controlled and place the fixing ring 1 on the ground where the roots of the jujube tree are located;
[0062] Step 3. Rotate the two fixing rings 1 so that one end of the two fixing rings 1 is closed;
[0063] Step 4. Start the drive motor 6 to drive the transmission gear 5 and the functional ring 2 to rotate through the drive gear 7, so that the fixing ring 1 is locked and the inner support ring 3 extends forward through the displacement wheel 16 to contact the tree trunk;
[0064] Step 5. The fixed ring 1 is used to spray the pests during the upward movement, and after the spraying is completed, the fixed ring 1 is retracted to continue spraying the next jujube tree. When it is necessary to continue spraying the jujube tree repeatedly, the fixed ring 1 is placed at the root of the jujube tree and does not move. By adding a remote control component to the drive motor 6, the liquid pump 13, the displacement motor 15 and the electric push rod 18, the drive motor 6, the liquid pump 13, the displacement motor 15 and the electric push rod 18 can be self-started by remote control to spray the jujube trees regularly.
