Description

Technical Field

[0001] The invention belongs to the technical field of fruit tree planting, in particular to a soil drilling and fertilizing device for roots of fruit trees in an orchard. Background Art

[0002] There are many kinds of fruit trees. In orchards, fruit trees are usually arranged for easy management. In the planting of fruit trees, in addition to the repair work of leaves and branches, they also need to be fertilized and irrigated to ensure that the roots of the fruit trees have sufficient nutrients. Fertilization is divided into root fertilization and foliar fertilization. When fertilizing the roots, it is necessary to drill holes near the roots of the fruit trees, apply fertilizer into the holes, and fill the holes. In order to improve the efficiency of root fertilization, fruit farmers often use drilling fertilization devices.

[0003] Chinese invention patent CN113115619B discloses a small orchard fruit tree root soil drilling and fertilization device, whose power mechanism can drive the casing to rise and fall and rotate simultaneously, and realize the drilling function through the spiral blades on the outer periphery of the casing. After each hole is drilled, the intermittent transverse movement mechanism will drive the translation plate to move an end distance, and under the action of the elastic mechanism, the position of the casing changes, and its movement stroke is a curve, and finally a circle of holes is formed around the fruit tree, which can effectively improve the fertilization effect and ensure the comprehensive absorption of fertilizer by the fruit tree root system. Combined with the mixing mechanism, it can ensure the comprehensive absorption of nutrients by the fruit tree root system, and the drilling is highly automatic, which can save manpower and improve work efficiency.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1. In the present invention, the connecting tube structure and the drill bit structure are driven to rotate by the rotating assembly, and the drill bit structure is driven to move downward under the action of the lifting assembly to perform drilling operations. During the drilling process, the crushed soil conveying structure exerts an upward force on the crushed soil, and part of the crushed soil is conveyed to the ground and stored in the soil collecting cover. When the drilling depth reaches the fertilization depth, the lifting assembly stops working, and the connecting tube structure rotates slowly. At the same time, the sealing assembly opens the discharge hole, and the fertilizer is discharged to the bottom of the hole through the discharge hole to fertilize the bottom of the hole. After the fertilization is completed, the sealing assembly closes the discharge port, and the drill bit structure is moved upward by the lifting assembly. The drill bit structure moves up a certain distance and then stops moving. The connecting tube structure rotates slowly in the reverse direction, at which time the crushed soil conveying structure exerts a downward force on the crushed soil, making the crushed soil below the drill bit structure dense, and the drill bit structure moves upward to a certain height again, and squeezes the crushed soil below again, and repeats the above work until the crushed soil at the opening is squeezed densely; before the drill bit structure moves upward, the fertilizer is automatically applied, and the soil collecting cover stores the crushed soil. When the drill bit structure moves upward, the crushed soil moves downward to fill the hole, thereby improving the convenience of fertilization and the efficiency of fertilization; when the connecting tube structure rotates slowly in the reverse direction, the crushed soil conveying structure can squeeze the crushed soil below the drill bit structure to improve the density of the crushed soil.

[0027] 2. When the drill bit structure in the present invention moves downward, the No. 1 rotating member abuts against the opening of the discharge hole to close the discharge hole, thereby preventing fertilizer leakage and preventing crushed soil from entering the connecting tube structure through the discharge hole; when fertilizing, the No. 1 motor drives the No. 1 connecting shaft to rotate, drives the No. 1 rotating member to rotate, and the No. 1 rotating member is moved away from the opening of the discharge hole, so that the fertilizer moves downward through the discharge hole for fertilization.

[0028] 3. In the present invention, the No. 1 connecting shaft is driven to rotate by the No. 1 motor, and the No. 1 connecting shaft drives the fertilizer conveying structure to rotate. The fertilizer conveying structure exerts a downward force on the fertilizer, generates an extrusion force on the crushed soil accumulated in the discharge hole, pushes the crushed soil out of the discharge hole, makes the discharge hole unobstructed, ensures the normal downward movement of the fertilizer, and improves the reliability of the drilling fertilization device.

[0029] 4. In the present invention, during the rotation of the driving shaft, the striking plate intermittently strikes the sliding structure to prevent the sliding structure from getting stuck and immobile, thereby improving the reliability of the movement of the soil collecting cover; the crushed soil in the soil collecting cover is easily accumulated on the outside of the crushed soil conveying structure to form a hollow cylindrical structure in the middle, thereby reducing the probability of the crushed soil moving into the hole, and the soil collecting cover is intermittently struck by the striking member to cause the soil collecting cover to vibrate, thereby increasing the probability of the crushed soil moving into the hole and improving the reliability of the drilling and fertilization device.

[0030] 5. When there is too little fertilizer in the fertilizer box structure of the present invention, the lifting plate is raised by the lifting assembly, so that the tubular structure of the fertilizer box structure is sleeved outside the discharge structure, and the rotating shaft of the No. 3 motor drives the conveying shaft to rotate, driving the spiral conveying structure to rotate. The spiral conveying structure exerts a force on the fertilizer entering the lower end of the structure, so that the fertilizer moves upward along the main pipe structure, moves the fertilizer to the upper end of the main pipe structure, and falls into the fertilizer box structure through the discharge structure, thereby adding fertilizer to the fertilizer box structure.

DETAILED DESCRIPTION

[0048] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0049] like Figure 1-Figure 15 As shown, a soil drilling and fertilizing device for roots of fruit trees in an orchard comprises a frame 1, a lifting plate 2, a lifting assembly 3, a drilling member 4, a rotating assembly 5, a sealing assembly 6 and a soil collecting cover 7;

[0050] The lower end of the frame 1 is connected to a traveling assembly 11; the traveling assembly 11 is used to drive the frame 1 to move;

[0051] The frame 1 is slidably connected to the lifting plate 2; the frame 1 is connected to the lifting assembly 3; the lifting assembly 3 is used to drive the lifting plate 2 to rise or fall;

[0052] The lifting plate 2 is connected to a drilling member 4; the drilling member 4 comprises a connecting tube structure 41, a drill bit structure 42, a soil crushing and conveying structure 43 and a fertilizer box structure 44; the connecting tube structure 41 is rotatably connected to the lifting plate 2; the soil crushing and conveying structure 43 is arranged on the outer wall of the connecting tube structure 41; the soil crushing and conveying structure 43 is spirally arranged along the outer wall of the connecting tube structure 41; the drill bit structure 42 is arranged at the lower end of the connecting tube structure 41; the fertilizer box structure 44 is arranged at the upper end of the connecting tube structure 41;

[0053] The drill bit structure 42 is symmetrically provided with discharge holes 421; the sealing assembly 6 is connected to the connecting tube structure 41; the sealing assembly 6 is used to realize the opening or closing of the discharge hole 421;

[0054] The lifting plate 2 is connected to a rotating assembly 5; the rotating assembly 5 is used to drive the connecting cylinder structure 41 to rotate;

[0055] A sliding structure 71 is provided on one side of the soil collecting cover 7; the sliding structure 71 is slidably connected to the frame 1; a No. 1 mounting groove 72 is provided on the soil collecting cover 7; a No. 1 elastic member 73 is provided in the No. 1 mounting groove 72; the lower end of the No. 1 elastic member 73 is fixedly connected to the bottom surface of the No. 1 mounting groove 72; the upper end of the No. 1 elastic member 73 is fixedly connected to the lifting plate 2; the soil collecting cover 7 is used to store crushed soil.

[0056] During operation, the fruit farmer moves the vehicle frame 1 to the vicinity of the root of the fruit tree through the walking assembly 11, so that the drill structure 42 is located at the fertilization position, and then drives the lifting plate 2 to move downward through the lifting assembly 3, and the lifting plate 2 drives the drilling member 4 and the No. 1 elastic member 73 to move downward. When the No. 1 elastic member 73 moves downward, the soil collecting cover 7 moves downward, so that the lower end of the soil collecting cover 7 contacts the ground, and the lifting plate 2 continues to move downward to compress the No. 1 elastic member 73. The No. 1 elastic member 73 generates pressure on the soil collecting cover 7, so that the soil collecting cover 7 contacts the ground. At this time, the drill structure 42 is close to the ground, and then rotates The component 5 drives the connecting tube structure 41 to rotate, drives the drill bit structure 42 to rotate, and at the same time, the drilling head structure 42 is driven downward by the lifting component 3 to perform the drilling operation. During the drilling process, the crushed soil conveying structure 43 exerts an upward force on the crushed soil, and transports part of the crushed soil to the ground and stores it in the soil collecting cover 7. When the drilling depth reaches the fertilization depth, the lifting component 3 stops working, so that the height of the drill bit structure 42 remains unchanged, and the connecting tube structure 41 is rotated slowly by the rotating component 5, and the discharge hole 421 is opened by the sealing component 6, and the fertilizer is discharged into the hole through the discharge hole 421. The bottom of the hole is discharged (there is fertilizer in the fertilizer box structure and the connecting pipe structure), and fertilizer is applied to the bottom of the hole. After the fertilization is completed, the sealing component 6 closes the discharge port, and the drill bit structure 42 is moved upward by the lifting component 3. The drill bit structure 42 moves up a certain distance and then stops moving. At this time, the connecting tube structure 41 is rotated in the reverse direction at a slow speed by the rotating component 5. At this time, the soil crushing and conveying structure 43 exerts a downward force on the soil crushing, so that the soil crushing moves downward, and the soil crushing under the drill bit structure 42 becomes dense. Then, the connecting tube structure 41 is rotated forward at a slow speed, and the soil crushing and conveying structure 43 exerts a downward force on the soil crushing, so that the soil crushing moves downward, and the soil crushing under the drill bit structure 42 becomes dense. The crushed soil on the side generates an upward force, making the crushed soil around and above the drill bit structure 42 loose, making it easier for the drill bit structure 42 and the crushed soil conveying structure 43 to move upward, and the drill bit structure 42 moves upward to a certain height again, and squeezes the crushed soil below again, repeating the above work until the crushed soil at the opening is squeezed densely, at which time the rotating assembly 5 stops working, and the lifting assembly 3 continues to move the drill bit structure 42 upward, and the first elastic member 73 generates a pulling force on the soil collecting cover 7, driving the soil collecting cover 7 to move upward, so that the soil collecting cover 7 is separated from the ground, making it easier to move the frame 1;

[0057] Before the drill bit structure 42 moves upward, the fertilizer is applied automatically to avoid manual application of fertilizer, thereby improving the convenience of fertilization and the efficiency of fertilization; the crushed soil is stored by the soil collecting cover 7, and when the drill bit structure 42 moves upward, the crushed soil moves downward to fill the hole, thereby avoiding manual filling of the hole, thereby improving the convenience of fertilization and the efficiency of fertilization; when the connecting tube structure 41 rotates slowly in the reverse direction, the crushed soil conveying structure 43 can squeeze the crushed soil under the drill bit structure 42 to improve the compactness of the crushed soil.

[0058] The sealing assembly 6 includes a No. 1 motor 61, a No. 1 connecting shaft 62 and a No. 1 rotating member 63; the No. 1 motor 61 is fixedly connected in the fertilizer box structure 44; the No. 1 connecting shaft 62 is connected in the connecting tube structure 41; the upper end of the No. 1 connecting shaft 62 is fixedly connected to the rotating shaft of the No. 1 motor 61; and the lower end of the No. 1 connecting shaft 62 is fixedly connected to the No. 1 rotating member 63.

[0059] When the drill bit structure 42 moves downward, the No. 1 rotating member 63 abuts against the opening of the discharge hole 421, closing the discharge hole 421 to prevent fertilizer leakage and prevent broken soil from entering the connecting tube structure 41 through the discharge hole 421; when fertilizing, the No. 1 motor 61 works, driving the No. 1 connecting shaft 62 to rotate, driving the No. 1 rotating member 63 to rotate, and the No. 1 rotating member 63 moves away from the opening of the discharge hole 421, so that the fertilizer moves downward through the discharge hole 421 for fertilization.

[0060] A fertilizer conveying structure 621 is provided on the outer wall of the No. 1 connecting shaft 62 ; the fertilizer conveying structure 621 is spirally arranged along the outer wall of the No. 1 connecting shaft 62 .

[0061] The crushed soil is easy to accumulate in the discharge hole 421. After the crushed soil is squeezed and compacted, the discharge hole 421 will be blocked. The No. 1 motor 61 drives the No. 1 connecting shaft 62 to rotate, and the No. 1 connecting shaft 62 drives the fertilizer conveying structure 621 to rotate. The fertilizer conveying structure 621 exerts a downward force on the fertilizer, and exerts an extrusion force on the crushed soil accumulated in the discharge hole 421 (during the process of the No. 1 rotating member 63 rotating one circle, the discharge hole 421 is closed for a part of the time, and the discharge hole 421 is open for the rest of the time. During the period when the discharge hole 421 is open, the fertilizer exerts a downward force on the accumulated soil. The accumulated crushed soil generates squeezing pressure), and the crushed soil is pushed out from the discharge hole 421, so that the discharge hole 421 becomes unobstructed, ensuring that the fertilizer moves downward normally (the fertilizer moves downward through the discharge hole 421 while the discharge hole 421 is open), thereby improving the reliability of the drilling fertilization device; after the drilling fertilization device is used, the fertilizer conveying structure 621 is driven to rotate by the No. 1 motor 61, and the fertilizer conveying structure 621 exerts a downward force on the fertilizer, so that the remaining fertilizer moves downward through the discharge hole 421, which is convenient for cleaning the remaining fertilizer.

[0062] The lifting assembly 3 includes a driving shaft 31, a No. 2 motor 32 and a No. 2 transmission member 33; the driving shaft 31 is rotatably connected to the frame 1; the lifting plate 2 is threadedly connected to the driving shaft 31; the No. 2 motor 32 is fixedly connected to the frame 1; the driving shaft 31 and the rotating shaft of the No. 2 motor 32 are transmitted through the No. 2 transmission member 33.

[0063] When the lifting plate 2 needs to move downward, the rotating shaft of the No. 2 motor 32 drives the driving shaft 31 to rotate through the No. 2 transmission member 33. The threaded structure of the driving shaft 31 generates a force on the threaded structure of the lifting plate 2. Because the lifting plate 2 is slidingly connected to the frame 1, the lifting plate 2 can only move up and down, thereby driving the lifting plate 2 to move downward and driving the drill structure 42 to move downward; when the lifting plate 2 needs to move upward, the rotating shaft of the No. 2 motor 32 rotates in the opposite direction, and the driving shaft 31 rotates in the opposite direction, driving the lifting plate 2 to move upward.

[0064] The lower end of the driving shaft 31 is connected to a rotating plate 91; one end of the rotating plate 91 is fixedly connected to the driving shaft 31; the other end of the rotating plate 91 is provided with a first sliding groove 911;

[0065] A striking plate 92 is slidably connected in the No. 1 sliding groove 911; a No. 2 mounting groove 921 is symmetrically provided on the striking plate 92; a No. 2 elastic member 93 is provided in the No. 2 mounting groove 921; one end of the No. 2 elastic member 93 abuts against the bottom surface of the No. 2 mounting groove 921; the other end of the No. 2 elastic member 93 abuts against the side surface of the No. 1 sliding groove 911;

[0066] A waist-shaped groove 922 is provided on the striking plate 92 ; a limiting member 94 is fixedly connected to the rotating plate 91 ; and the limiting member 94 passes through the waist-shaped groove 922 .

[0067] When the driving shaft 31 rotates, the rotating plate 91 is driven to rotate, and the rotating plate 91 drives the striking plate 92 to rotate. When the striking plate 92 rotates toward the soil collecting cover 7, the end of the striking plate 92 hits the sliding structure 71, and the rotating plate 91 continues to rotate, so that the striking plate 92 slides into the second installation groove 921, so that the end of the striking plate 92 slides on the side of the sliding structure 71, so that the striking plate 92 passes over the sliding structure 71. After the striking plate 92 passes over the sliding structure 71, the second elastic member 93 causes the striking plate 92 to move toward the second installation groove 921. During the rotation of the driving shaft 31, the striking plate 92 intermittently strikes the sliding structure 71 to prevent the sliding structure 71 from getting stuck and immobilizing, thereby improving the reliability of the movement of the soil collecting cover 7; the crushed soil is easily accumulated on the outside of the crushed soil conveying structure 43 in the soil collecting cover 7, forming a hollow cylindrical structure in the middle, thereby reducing the probability of the crushed soil moving into the hole, and the soil collecting cover 7 is intermittently struck by the striking member, so that the soil collecting cover 7 vibrates, thereby increasing the probability of the crushed soil moving into the hole and improving the reliability of the drilling and fertilizing device.

[0068] The drilling fertilization device also includes an adding component 8; the adding component 8 includes a containing box 81, a conveying pipe 82, a conveying shaft 83 and a third motor 84;

[0069] A containing box 81 is fixedly connected to the vehicle frame 1; a conveying pipe 82 is fixedly connected to the vehicle frame 1; the conveying pipe 82 comprises a main pipe structure 821, an entry structure 822, a discharge structure 823 and a connecting structure 824; an entry structure 822 and a connecting structure 824 are arranged at one end of the main pipe structure 821; the entry structure 822 is communicated with the containing box 81; a discharge structure 823 is arranged at the other end of the main pipe structure 821; a conveying shaft 83 is connected inside the conveying pipe 82; a spiral conveying structure 831 is arranged on the conveying shaft 83; a No. 3 motor 84 is fixedly connected inside the connecting structure 824; the conveying shaft 83 is fixedly connected to the rotating shaft of the No. 3 motor 84; a tubular structure 441 is arranged at the upper end of the fertilizer box structure 44.

[0070] When there is too little fertilizer in the fertilizer box structure 44, the lifting plate 2 is raised by the lifting assembly 3, so that the tubular structure 441 of the fertilizer box structure 44 is sleeved outside the discharge structure 823, and then the No. 3 motor 84 works, and the rotating shaft of the No. 3 motor 84 drives the conveying shaft 83 to rotate, and drives the spiral conveying structure 831 to rotate. The spiral conveying structure 831 exerts a force on the fertilizer entering the lower end of the structure 822, so that the fertilizer moves upward along the main pipe structure 821, and the fertilizer moves to the upper end of the main pipe structure 821, and falls into the fertilizer box structure 44 through the discharge structure 823, adding fertilizer to the fertilizer box structure 44, thereby improving the convenience of the drilling fertilization device.
