Description

Technical Field

[0001] This utility model belongs to the field of nut planting technology, specifically relating to a macadamia nut spraying production line. Background Technology

[0002] Macadamia nuts, also known as Hawaiian nuts, Australian walnuts, and Queensland chestnuts, are evergreen tall trees belonging to the genus *Macadamia* in the family Proteaceae. Macadamia plants grow to 5-15 meters tall, with leathery, oblong to oblanceolate leaves. Spraying macadamia trees with pesticides often involves manual labor or spray carts. This manual operation is not feasible with automated spraying lines that allow for long-term use of a single application to spray an entire row of macadamia trees. Existing automated spraying lines cannot flexibly adjust the nozzle angle or adapt to changes in the tree's position. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a macadamia nut spraying production line. After the slide is laid, the slide moves and sprays on the slide, which can spray an entire row of nuts.

[0004] A macadamia nut spraying production line includes a slide rail with a slider slidably mounted on its surface. A water spray plate is rotatably mounted on one side of the slider, and a nozzle is mounted on one side of the water spray plate. A control plate is mounted on one side of the slide rail, and a control groove is formed on the upper surface of the control plate. A control strip is slidably mounted on one side of the slider, with one end of the control strip overlapping the control groove and the other end overlapping the water spray plate. A traveling mechanism is provided on the surface of the slider, including a traveling wheel and a drive wheel. A water spray channel is formed inside the water spray plate, and an adjusting plate is slidably mounted inside the water spray channel. A sealing plate is integrally mounted on one side of the adjusting plate.

[0005] The beneficial effects of the above technical solution are as follows:

[0006] After the slide is laid, the slider moves and sprays on the slide, which can spray an entire row of nuts without manual operation. By installing a control plate on the slide and setting it to correspond to the trees, the spray plate can automatically rotate its angle when it gets close to or away from the trees, so that the angle tends to the center of the tree. When it gets close to or away from the trees, the spray pressure can be increased by reducing the water outlet area, so that it can spray farther when it gets close to or away from the trees. Even when it is far away from the trees, it can still spray the sides of the trees. Attached Figure Description

[0014] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 6 The embodiments are described in detail below.

[0015] This embodiment provides a macadamia nut spraying production line, as shown in the attached diagram. Figure 1 As shown, the instruction manual is attached. Figure 1 This is a top view, such as Figure 1 The slide 1 extends to both sides, and is fixed to the ground at both ends by support rods 17. The support frame is inserted into the ground, and the slide 1 is above the ground. On one side of the slide, there are rows of macadamia nuts planted. Due to the top-down view, the trees are represented by cylinders. Since the growth trend of the trees is to spread outwards from the edges, the trees are represented as cylinders. After the slider 2 reaches the area of ​​the trees, it will swing and rotate left and right. If the spray plate of this solution does not rotate, then as the slider 2 slides, when the slider 2 is directly facing the tree, it will spray along the direction of the tree. Figure 1 As shown, when slider 2 moves away from or near the tree, nozzle 4 does not spray towards the tree. Furthermore, because slider 2 moves away, nozzle 4 needs to spray with greater force to reach the edge of the tree, resulting in wasted spray.

[0016] As attached Figure 1As shown, in this design, the slider 2 is slidably mounted on the slide rail 1. The upper and lower ends of the slider 2 are equipped with rotating wheels 8, which fit against the upper and lower ends of the slide rail 1, allowing the slider 2 to slide on the slide rail 1. The movement of the slider 2 mainly relies on the drive wheel 9. The surface of the drive wheel 9 has a certain degree of softness and is in close contact with the slide rail 1. By increasing friction, relative movement between the drive wheel 9 and the slide rail 1 is facilitated. A servo motor needs to be installed on one side of the drive wheel 9. While a conventional motor drives the drive wheel 9 to rotate, this design uses a servo motor with a power-off self-locking function. Thus, the drive wheel 9 rotates under the action of the motor, and this rotation causes the slider 2 to slide on the slide rail 1.

[0017] To address issues such as wasted pesticide from nozzle 4, this solution includes a control plate 5 positioned perpendicular to the slide 1 at the tree's center. This plate can be bolted to one side of the slide 1. Figure 1 As shown;

[0018] As per the instruction manual Figure 3-4 As shown, the control panel 5 is displayed with its lower surface facing upwards. It can be seen that the upper surface of the control panel 5 has a control groove 7. The control groove 7 is composed of two inclined grooves, one shorter and one longer, as shown... Figure 3 As shown, when moving from the shorter groove to the longer groove, since the travel direction of this design is diagonally upward, a torsion spring 13 is set at the rotation center of the slider 2 and the water spray plate 3. This torsion spring 13, without being subjected to external force, ensures that the direction of the water spray plate 3 is perpendicular to the slide 1, which is also the same as the instruction manual attached. Figure 3 In this state, because slider 2 moves laterally, when it reaches the left side of control plate 5, control bar 6 will reach the shorter slot inlet. The angle of the spray plate 3 in this design is controlled by control bar 6. One side of control bar 6 has a straight slot that overlaps one side of spray plate 3, and control bar 6 slides perpendicular to one side of slider 2, as shown in the instruction manual. Figure 3-4 As shown, there is an elliptical rod on one side of the slider 2. The control bar 6 is slidably mounted on the elliptical rod (the hole in the control bar 6 is also elliptical). This allows the slider 2 to limit the control bar 6 to slide along the rotation center of the spray plate 3. Since one end of the control bar 6 overlaps the spray plate 3 through the slot, the control bar 6 moving closer to or further away from the spray plate 3 can cause the spray plate 3 to rotate left or right. Furthermore, due to the relatively long segment of the control groove 7, which is an oblique long groove, it allows... Figure 4Slider 2 moves in the direction of travel, and under the action of control groove 7, control plate 5 moves away from water spray plate 3 (the bottom of control plate 5 has a round block that overlaps on control groove 7), causing water spray plate 3 to rotate clockwise. At this time, the position of water spray plate 3 is facing the center of the tree. Therefore, in the process of moving away from the center, water spray plate 3 can rotate towards the center of the tree to spray pesticide. Similarly, when it is close to the center of the tree, water spray plate 3 rotates counterclockwise and moves towards the center. This is the function of control groove 7. As slider 2 continues to move, it is separated from control plate 5. Under the action of torsion spring 13, water spray plate 3 returns to the vertical slide rail 1. The installation position of control plate 5 corresponds to the position of the tree, and the number of control plates 5 installed at this position corresponds to the number of trees in a row.

[0019] The previous paragraph introduced that the water spray plate 3 rotates when it approaches and moves away from the tree. Based on this function, an arc groove 14 is set. The arc groove 14 is set on one side of the slider 2, and the two sides are offset downwards, with the middle being the highest point. Since this design will rotate, no matter which direction the water spray plate 3 rotates, it will tend downwards. Therefore, a sealing plate 12 is vertically slidably set in the middle of the water spray plate 3. One end of the sealing plate 12 overlaps the arc groove 14. So when the water spray plate 3 rotates, the sealing plate 12 will move downwards along the water spray plate 3. One end of the sealing plate 12 extends through the interior of the water spray channel 10. In order to control the interior, a through hole 15 is opened on one side of the water spray plate 3, and the sealing plate 12 blocks the through hole 15, so that the liquid cannot be discharged from one side of the sealing plate 12.

[0020] A water pipe 16 is connected to the bottom of the spray plate 3. The other end of the water pipe 16 extends into the water tank for preparing the medicine mixture and is installed at the outlet of the water pump. The water pump is placed in the water tank so that the water pump delivers water to the water pipe 16 and finally reaches the spray plate 3. The water pipe 16 in this solution is very long and is a flexible hose, so it can adapt to the movement of the slider 2.

[0021] The rotation of the spray plate 3 causes the sealing plate 12 to move downwards. The sealing plate 12 extends internally and is integrally fitted with an adjusting plate 11. The downward movement of the adjusting plate 11 allows the valve plate 18 on the nozzle 4 to rotate. One end of the nozzle 4 can spray water, and the other end of the nozzle 4 is rotatably fitted with the valve plate 18. The valve plate 18 has a valve hole 19, which corresponds to the misalignment on the nozzle 4. This is the maximum drain outlet of the nozzle 4. If the adjusting plate 11 moves downwards at this time, because one end of the valve plate 18 has a transverse slot 21, one side of the adjusting plate 11 extends into the transverse slot. A small cylinder is located on the slot 21. Therefore, the adjusting plate 11 moves downward to make the valve plate 18 rotate. The rotation of the valve plate 18 causes the valve hole 19 and the misalignment hole 20 to be misaligned, reducing the water inlet area of ​​the nozzle 4. Since the water pump in this scheme adopts a constant water output speed, the reduced water inlet area on one side of the nozzle 4 results in a pressurization effect, making the medicine spray farther. In summary, the larger the rotation angle of the spray plate 3, the smaller the water inlet area inside the nozzle 4, and the stronger the pressure. Moreover, the larger the rotation angle of the spray plate 3, the longer the distance from the spray plate 3 to the center of the tree.

[0022] A slider 2 is slidably mounted on the surface of the slide 1. A water spray plate 3 is rotatably mounted on one side of the slider 2. A nozzle 4 is mounted on one side of the water spray plate 3. A control plate 5 is mounted on one side of the slide 1. A control groove 7 is formed on the upper surface of the control plate 5. A control strip 6 is slidably mounted on one side of the slider 2. One end of the control strip 6 overlaps with the control groove 7, and the other end of the control strip 6 overlaps with the water spray plate 3. A traveling mechanism is provided on the surface of the slider 2. The traveling mechanism includes a traveling wheel 8 and a drive wheel 9. A water spray channel 10 is formed inside the water spray plate 3. An adjusting plate 11 is slidably mounted inside the water spray channel 10. A sealing plate 12 is integrally mounted on one side of the adjusting plate 11. A torsion spring 13 is provided above the slider 2. An arc-shaped section is formed on one side of the slider 2. The surface of the arc-shaped groove 14 is covered with a sealing plate 12. A through hole 15 is provided on one side of the spray plate 3. A water pipe 16 is connected to the bottom of the spray channel 10. A nozzle 4 is connected to one side of the spray channel 10. A water outlet hole is provided on one side of the nozzle 4. A valve plate 18 is rotatably provided inside the nozzle 4. A valve hole 19 is provided on the surface of the valve plate 18. A misalignment hole 20 is provided inside the nozzle 4. A transverse groove 21 is integrally provided on one side of the valve plate 18. An adjusting plate 11 is attached to the surface of the transverse groove 21.
