Technical Field
[0001] This utility model relates to the field of tobacco planting technology, specifically to a fixed-distance hole-digging fertilizer applicator for tobacco transplanting. Background Technology
[0002] Tobacco seedling transplanting refers to the process of transplanting tobacco seedlings from the seedling stage to the tobacco field, and it is an important part of the tobacco planting process. The quality of transplanting directly affects the growth of the seedlings and the final yield. Transplanting methods include conventional mulching transplanting, seedling transplanting under mulch, and well-type transplanting, and different transplanting methods have different effects on the growth and yield of tobacco seedlings.

All ends are connected to the lower chamber; the material conveying channel is inclined, and the upper end of the material conveying channel is connected to the upper chamber, and the lower end is connected to the bottom of the corresponding installation cavity. A sealing ball for blocking the material conveying channel is movably installed in the installation cavity. A vertically arranged connecting rod is fixedly installed on the top of the sealing ball. The upper end of the connecting rod passes through the punching cone and is fixedly installed with a baffle. A spring is sleeved on the connecting rod in the installation cavity. The punching cone is a rotating body with a cylindrical upper part and a frustum-shaped lower part. A discharge hole communicating with the lower chamber is concentrically opened at the bottom of the punching cone. A pusher assembly is provided in the lower chamber.

The lower end of the connecting rod extends out of the lower chamber through the discharge hole and is fixedly installed with a conical block. The top surface of the conical block is adapted to the bottom surface of the punching cone.
[0007] Preferably, the lifting device includes a speed-increasing mechanism and a reciprocating mechanism. The reciprocating mechanism includes a reciprocating screw that is rotatably mounted on the bottom of the trolley, a reciprocating nut that is threaded onto the reciprocating screw, and a connecting pipe that is concentrically fixed at the lower end of the reciprocating nut. A punch is fixedly mounted at the lower end of the connecting pipe. A limit ring is fixedly mounted on one side of the reciprocating nut. A slide rod is slidably mounted inside the limit ring.

[0008] Preferably, the drive mechanism includes a drive box fixedly mounted on the trolley, and a battery and a drive motor fixedly mounted inside the drive box. The battery and the drive motor are electrically connected. Pulleys are fixedly mounted on the output shaft of the drive motor and the wheel axle of the trolley, and the same transmission belt is mounted on the two pulleys.
[0009] Preferably, the speed-increasing mechanism includes a large bevel gear fixedly mounted on the axle of the trolley, a rotating shaft I and a rotating shaft II rotatably mounted on the trolley, and a drive gear fixedly mounted on the upper end of the reciprocating screw.

[0012] Beneficial Effects: Compared with the prior art, this utility model provides a fixed-distance hole-digging fertilizer applicator for tobacco transplanting. This fixed-distance hole-digging fertilizer applicator for tobacco transplanting has a unique structure and is easy to use. The drive motor drives the wheels of the trolley to rotate on the one hand, and drives the reciprocating screw to rotate on the other hand through the speed-increasing mechanism. After the reciprocating screw rotates, it drives the reciprocating nut to move up and down. When the insert block moves down and the conical block contacts the ground, the push-top component is compressed, and the conical block abuts against the insert block, so that the lower part of the insert block forms a conical rotating body, thereby opening a hole in the ground. When the insert block is inserted into the ground, the baffle contacts the ground, the sealing ball moves up, and the fertilizer in the upper chamber flows into the lower chamber through the conveying channel and the installation cavity. Since the conical block and the insert block are abutting together at this time, the discharge hole is blocked. When the drilling cone moves up, the conical block separates from the drilling cone under the action of the push-top component, the discharge hole opens, and the fertilizer in the lower chamber can flow out from the discharge hole, completing the fertilization.
[0013] Through the precise transmission of the speed-increasing mechanism and reciprocating screw, the spacing of the planting holes on the ground is ensured to be consistent, thereby ensuring the consistent distance between adjacent plants and improving the growth quality of tobacco seedlings. In addition, while the holes are being opened, the device automatically transports fertilizer from the upper chamber to the lower chamber and applies it through the discharge hole, reducing the steps of manual fertilization, improving fertilization efficiency, and reducing labor costs and the labor intensity of operators.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Example 1: This Example 1 provides a fixed-distance hole-digging fertilizer applicator for tobacco transplanting. It is a direct improvement on existing hole-digging devices, with a unique structure. Please refer to [link / reference]. Figure 1-5 As shown, it includes a trolley 1, a feed hopper 5 mounted on the trolley 1, a drive mechanism 2 for moving the trolley 1, and a lifting device mounted at the bottom of the trolley 1, the lifting device being connected to the wheel axle of the trolley 1 via a drive mechanism.
[0022] The lifting device includes a speed-increasing mechanism 3 and a reciprocating mechanism 4. The reciprocating mechanism 4 includes a reciprocating screw 41 that is vertically rotatably mounted on the bottom of the trolley 1, a reciprocating nut 42 threaded onto the reciprocating screw 41, and a connecting pipe 45 concentrically fixedly mounted on the lower end of the reciprocating nut 42. A punching cone 46 is fixedly mounted on the lower end of the connecting pipe 45. A limit ring 43 is fixedly mounted on one side of the reciprocating nut 42.

The same transmission belt 25 is mounted on the two pulleys 24, and the two pulleys 24 are connected by transmission belt 25.
[0023] The speed-increasing mechanism 3 includes a large bevel gear 31 fixedly mounted on the axle of the trolley 1, a rotating shaft I and a rotating shaft II rotatably mounted on the trolley 1, and a drive gear 39 fixedly mounted on the upper end of the reciprocating screw 41. A small bevel gear 32 and a large gear I 33 are fixedly mounted on the rotating shaft I, and a small gear III 37 and a large gear III 38 are rotatably mounted on it, with the small gear III 37 and the large gear III 38 fixedly connected together. A small gear I 34 and a large gear II 35 are fixedly mounted on the rotating shaft II, and a small gear II 35 is rotatably mounted on it. Wheel II 36, small bevel gear 32 meshes with large bevel gear 31 for transmission, large gear I 33 meshes with small gear I 34 for transmission, large gear II 35 meshes with small gear III 37 for transmission, and small gear II 36 meshes with large gear III 38 and drive gear 39 for transmission respectively; through speed-increasing mechanism 3, when the wheel of the trolley 1 rotates once, the reciprocating screw 41 can rotate n times, which speeds up the up-and-down reciprocating movement of the reciprocating nut 42, so that when the trolley 1 moves slowly, the drilling cone 46 can quickly move down and make a hole in the ground.
[0024] The lifting device is equipped with a movable end that can move up and down reciprocally. A drilling cone 46 is fixedly installed on the movable end. The drilling cone 46 has an upper chamber 47, a lower chamber 48, a material conveying channel 49, and an installation cavity 410. There are multiple material conveying channels 49 and installation cavities 410, and they correspond one-to-one. A connecting hose 6 is fixedly installed at the bottom of the feed hopper 5. The lower end of the connecting hose 6 is connected to the upper chamber 47. The multiple installation cavities 410 are evenly distributed along the circumference, and the lower ends of the multiple installation cavities 410 are all connected to the lower chamber. The chamber 48 is connected; the material conveying channel 49 is inclined, and the upper end of the material conveying channel 49 is connected to the upper chamber 47, and the lower end is connected to the bottom of the corresponding installation cavity 410. A blocking ball 411 for blocking the material conveying channel 49 is movably installed in the installation cavity 410. A vertically arranged connecting rod 412 is fixedly installed on the top of the blocking ball 411. The upper end of the connecting rod 412 passes through the drilling cone 46 and is fixedly installed with a baffle 413. A spring 414 is sleeved on the connecting rod 412 in the installation cavity 410.
[0025] The punching cone 46 is a rotating body with a cylindrical upper part and a frustum-shaped lower part. A discharge hole 415, communicating with the lower chamber 48, is concentrically opened at the bottom of the punching cone 46. A pusher assembly is installed inside the lower chamber 48. A connecting rod 418 is fixedly installed at the output end of the pusher assembly. The lower end of the connecting rod 418 extends out of the lower chamber 48 through the discharge hole 415 and is fixedly installed with a conical block 420. The top surface of the conical block 420 is adapted to the bottom surface of the punching cone 46. When the top of the conical block 420... When the surface of the punch 46 contacts the bottom surface of the punch 46, the lower part of the punch 46 and the cone block 420 together form a cone-shaped rotating body; the push assembly includes a fixed tube 416 that is fixedly installed on the top surface inside the lower compartment 48 and sealed at both ends. The lower end of the fixed tube 416 has a through hole concentrically opened. A limit plate 417 is vertically slidably fitted inside the fixed tube 416. The upper end of the limit plate 417 is provided with a top spring 419, and the lower end extends out of the through hole and is fixedly connected to the connecting rod 418.
[0026] Working principle: When the operator uses the device to dig holes for fertilization, the drive motor 23 is started first. The drive motor 23 drives the wheels of the trolley 1 to rotate, and at the same time drives the reciprocating screw 41 to rotate through the speed-increasing mechanism 3. After the reciprocating screw 41 rotates, it drives the reciprocating nut 42 to move up and down, thereby driving the drilling cone 46 to dig holes in the ground. In the initial state, the cone block 420 is separated from the drilling cone 46 under the action of the pushing component. When the drilling cone 46 moves down and the cone block 420 contacts the ground, the pushing component is compressed, and the cone block 420 comes into contact with the drilling cone 46. This causes the lower part of the drilling cone 46 to form a conical rotating body. When the drilling cone 46 is inserted into the ground, the baffle 413 contacts the ground. At this time, the sealing ball 411 moves upward, and the fertilizer in the upper chamber 47 flows into the lower chamber 48 through the conveying channel 49 and the installation cavity 410. Since the conical block 420 is in contact with the drilling cone 46 at this time, the discharge hole 415 is blocked. When the drilling cone 46 moves upward, the conical block 420 separates from the drilling cone 46 under the action of the pushing component. At this time, the discharge hole 415 opens, and the fertilizer in the lower chamber 48 can flow out from the discharge hole 415, thus completing the fertilization.
[0027] Example 2: The difference between Example 2 and Example 1 is as follows: Figure 4 As shown, the top and bottom of the cone block 420 are both conical rotating bodies. The bottom of the discharge hole 415 is adapted to the cone block 420. Two support legs 7 are fixedly installed on the bottom of the rear side of the trolley 1. Both support legs 7 are close to the wheels of the trolley 1 on the adjacent side. By setting the top of the cone block 420 to be conical, some fertilizer can be prevented from falling on the top surface of the cone block 420. The two support legs 7 can support the trolley 1.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
