Description

Technical Field

[0001] This application relates to the field of fertilization device technology, and more specifically, to a fertilization device for black chokeberry. Background Technology

[0002] Black chokeberry is a fruit tree variety with high economic value. It thrives in fertile soil, requiring not only basal fertilizer at transplanting but also timely and appropriate top dressing. Traditional fertilization methods rely heavily on manual application using simple tools. This typically involves bending over to dig a hole at the base of the plant and then applying fertilizer. Manual fertilization is prone to over- or under-fertilization, affecting plant growth uniformity and is labor-intensive and inefficient, especially in large-scale planting, consuming significant time and manpower. Due to the unique root structure and growth characteristics of black chokeberry, fertilizer needs to be accurately applied to the soil around the roots to ensure nutrient absorption. Existing equipment often fails to achieve precise mechanized fertilization. Therefore, we propose a fertilization device for black chokeberry. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] The purpose of this application is to provide a fertilization device for black chokeberry, which solves the technical problems in the background art and realizes efficient, accurate and convenient fertilization operation. By combining the mobility of the handcart with the advanced mechanized automatic fertilization mechanism, it can effectively improve fertilization efficiency, reduce manual labor intensity, and ensure that fertilizer is evenly applied to the soil around the roots of the plant, thereby promoting the growth of black chokeberry.

[0005] 2. Technical Solution

[0006] This application provides a fertilization device for black chokeberry, comprising: a handcart, on which a battery box and a fertilizer box are fixedly mounted by bolts, and a fertilizer pipe assembly is connected to the bottom of the fertilizer box; and a fertilizer drive mechanism is mounted on the frame of the handcart.

[0007] The fertilizer pipe assembly includes a corrugated pipe, the upper end of which is threadedly installed at the bottom discharge port of the fertilizer box. The bottom end of the corrugated pipe is threadedly connected to a volute, and a distribution plate is rotatably installed inside the volute. The bottom end of the volute is fixedly connected to a discharge pipe, which has a beveled end. An elliptical sealing plate is rotatably hinged to the discharge pipe at the beveled end. After the discharge pipe is inserted into the soil at the root of the black chokeberry, the elliptical sealing plate rotates and flips open.

[0008] The fertilizer application drive mechanism includes a concave seat, which is fixedly mounted on the frame of a handcart. A slide is slidably mounted on the concave seat via a drive structure. The slide is fixedly connected to a volute. A rack is fixedly mounted on the concave seat. A gear is fixedly connected to the dispensing disc via a shaft, and the gear meshes with the rack.

[0009] By adopting the above technical solution, this device centrally installs a battery box, fertilizer box, fertilizer pipe assembly, and fertilizer drive mechanism on a handcart. The fertilizer pipe assembly adopts a combination structure of corrugated pipe, volute, distribution plate, discharge pipe, and elliptical sealing plate. Fertilizer is collected from the fertilizer box through the corrugated pipe. As the slide moves the volute downwards, the volute drives the discharge pipe to insert into the soil. Due to the meshing connection of the gear and rack, the distribution plate inside the volute is forced to rotate, allowing the fertilizer to be smoothly delivered into the discharge pipe. When the discharge pipe is inserted into the soil... Once the material reaches a certain depth, the elliptical sealing plate installed at the oblique cut at the bottom of the discharge pipe can be forced to rotate and flip open through a mechanical structure to ensure smooth discharge of fertilizer. When the discharge pipe is pulled out, the elliptical sealing plate can automatically close to prevent fertilizer leakage. This design makes the fertilization process more precise and smooth, effectively avoiding fertilizer waste and environmental pollution. It solves the problems of slow fertilization efficiency and high labor intensity caused by traditional manual fertilization operations with bent-over posture. It can quickly complete large-area fertilization operations and significantly improve work efficiency.

[0010] Optionally, the handcart has a front wheel and two rear wheels rotatably mounted on its frame, and an electric control switch is detachably mounted on the handcart's handle.

[0011] By adopting the above technical solution, the handcart is equipped with one front wheel and two rear wheels, making it easy to push and move to the location of the black chokeberry that needs fertilization by holding the handle. The handle is also equipped with a detachable electric control switch for easy operation.

[0012] Optionally, the volute is provided with an internal cavity structure that matches the material distribution plate and is connected to the corrugated pipe and the discharge pipe. The material distribution plate is provided with multiple arc-shaped grooves along its edge.

[0013] By adopting the above technical solution, the corrugated pipe has good flexibility and extensibility, and can adapt to different installation angles and position changes. The corrugated pipe receives fertilizer from the fertilizer box, and the distribution plate inside the volute rotates, so that the arc groove of the distribution plate transports the fertilizer to the discharge pipe.

[0014] Optionally, a hinge sleeve is fixedly sleeved at the bottom end of the discharge pipe, an L-shaped block is fixedly connected to the elliptical sealing plate, the L-shaped block is rotatably hinged to the hinge sleeve via a shaft, and a return spring is fixedly connected between the L-shaped block and the hinge sleeve. A U-shaped seat is fixedly provided on the hinge sleeve, and a T-shaped rod is rotatably connected to the U-shaped seat. The T-shaped rod is slidably connected to the concave seat.

[0015] By adopting the above technical solution, under normal conditions, the elliptical sealing plate connected to the L-shaped block is pressed against the discharge cut at the bottom of the discharge pipe by the elastic force of the return spring, so that the bottom of the discharge pipe will not discharge material. When the T-shaped rod moves down and touches the concave seat, the L-shaped block rotates along the hinge sleeve and overcomes the elastic resistance of the return spring, so that the elliptical sealing plate rotates and flips open, thereby allowing the fertilizer in the discharge pipe to fall out.

[0016] Optionally, the concave seat is provided with a strip-shaped guide groove, the T-shaped rod is slidably installed along the strip-shaped guide groove, and a round stop block is fixed at the upper end of the T-shaped rod, and the round stop block is larger than the strip-shaped guide groove.

[0017] By adopting the above technical solution, during the rotation of the L-shaped block along the hinge sleeve, the T-shaped rod can be slidably installed along the strip guide groove. When the round stop block at the upper end of the T-shaped rod abuts against the concave seat, the elliptical sealing plate is forced to passively rotate and flip open.

[0018] Optionally, the concave seat is further provided with a sliding groove, a motor is fixedly installed on the upper surface of the concave seat, the output end of the motor is driven by a lead screw, the lead screw is rotatably connected to the concave seat, and the lead screw is threadedly connected to the slide block, and the slide block is slidably installed along the sliding groove.

[0019] By adopting the above technical solution, the motor is started by an electric control switch, and the output end of the motor drives the lead screw to rotate, causing the slide to slide along the groove opened in the concave seat, which in turn drives the volute and the discharge pipe to move together, so as to realize the purpose of inserting the discharge pipe into the soil or pulling it out of the soil.

[0020] 3. Beneficial effects

[0021] One or more technical solutions provided in this application have at least the following technical effects or advantages: Using a handcart as a carrier, operators can easily push and move it in the field, eliminating the need for frequent handling of fertilizer and fertilization equipment, greatly saving time and effort. The mechanized automatic fertilization design allows operators to easily control the motor's start and stop via an electric switch. During the process of the volute driving the discharge pipe downwards into the soil, the meshing of gears and racks causes the distribution disc to rotate passively, allowing the fertilizer in the fertilizer box to be smoothly conveyed to the discharge pipe through the corrugated pipe. Furthermore, the upper end of the T-shaped rod is limited by the concave seat, forcing the elliptical sealing plate at the bottom of the discharge pipe to rotate and open, thus accurately delivering the fertilizer in the discharge pipe to the soil around the roots of the black chokeberry. This solves the problems of slow fertilization efficiency and high labor intensity caused by traditional manual fertilization operations involving bending over, enabling rapid completion of large-area fertilization operations and significantly improving work efficiency.

Detailed Implementation

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1 to 5 This application provides a fertilization device for black chokeberry, comprising: a handcart 1, a battery box 6 and a fertilizer box 2 are fixedly installed on the frame of the handcart 1 by bolts, a fertilizer pipe assembly 4 is connected to the bottom of the fertilizer box 2, and a fertilizer drive mechanism 5 is installed on the frame of the handcart 1.

[0030] The fertilizer pipe assembly 4 includes a corrugated pipe 41, the upper end of which is threadedly installed at the bottom discharge port of the fertilizer box 2. The bottom end of the corrugated pipe 41 is threadedly connected to a volute 43. A distribution plate 44 is rotatably installed inside the volute 43. The bottom end of the volute 43 is fixedly connected to a discharge pipe 42. The bottom end of the discharge pipe 42 is provided with a slanted cut. An elliptical sealing plate 46 is rotatably hinged to the discharge pipe 42 at the slanted cut. After the discharge pipe 42 is inserted into the soil at the root of the black chokeberry, the elliptical sealing plate 46 rotates and flips open.

[0031] The fertilizer application drive mechanism 5 includes a concave seat 52, which is fixedly mounted on the frame of the handcart 1. A slide block 54 is slidably mounted on the concave seat 52 via a drive structure. The slide block 54 is fixedly connected to the volute 43. A rack 55 is fixedly mounted on the concave seat 52. A gear 45 is fixedly connected to the distribution plate 44 via a shaft, and the gear 45 meshes with the rack 55. This device centrally mounts a battery box 6, a fertilizer box 2, a fertilizer application pipe assembly 4, and a fertilizer application drive mechanism 5 on the handcart 1. The fertilizer application pipe assembly 4 adopts a combination structure of a corrugated pipe 41, a volute 43, a distribution plate 44, a discharge pipe 42, and an elliptical sealing plate 46. The corrugated pipe 41 receives fertilizer from the fertilizer box 2. When the slide block 54 drives the volute 43 to move downward, the volute 43 drives the discharge pipe 42. When inserted into the soil, the meshing connection between gear 45 and rack 55 forces the distribution plate 44 inside the volute 43 to rotate, allowing fertilizer to be smoothly delivered into the discharge pipe 42. After the discharge pipe 42 is inserted into the soil to a certain depth, the elliptical sealing plate 46 installed at the oblique cut at the bottom of the discharge pipe 42 can be forced to rotate and flip open through the mechanical structure to ensure that the fertilizer is discharged smoothly. When the discharge pipe 42 is pulled out, the elliptical sealing plate 46 can automatically close to prevent fertilizer leakage. This design makes the fertilization process more precise and smooth, effectively avoiding fertilizer waste and environmental pollution. It solves the problems of slow fertilization efficiency and high labor intensity caused by traditional manual fertilization operations with bent backs. It can quickly complete large-area fertilization operations and significantly improve work efficiency.

[0032] Reference Figure 1 and Figure 2 The handcart 1 has a front wheel 11 and two rear wheels 12 mounted on its frame. An electric control switch 3 is detachably mounted on the handle of the handcart 1. The handcart 1 is easy to push and move to the location of the black chokeberry that needs to be fertilized by holding the handle by the front wheel 11 and two rear wheels 12. The electric control switch 3 is detachably mounted on the handle for easy operation.

[0033] Reference Figure 3 and Figure 4 The volute 43 has an internal cavity structure that matches the distribution plate 44 and is connected to the corrugated pipe 41 and the discharge pipe 42. The distribution plate 44 has multiple arc-shaped grooves 441. The corrugated pipe 41 has good flexibility and extensibility and can adapt to different installation angles and position changes. The corrugated pipe 41 receives fertilizer from the fertilizer box 2. The distribution plate 44 rotates in the volute 43, so that the arc-shaped grooves 441 of the distribution plate 44 transport the fertilizer to the discharge pipe 42.

[0034] Reference Figure 3 and Figure 5A hinge sleeve 47 is fixedly sleeved on the bottom end of the discharge pipe 42. An L-shaped block 48 is fixedly connected to an elliptical sealing plate 46. The L-shaped block 48 is rotatably hinged to the hinge sleeve 47 via a shaft, and a return spring 471 is fixedly connected between the L-shaped block 48 and the hinge sleeve 47. A U-shaped seat 481 is fixedly provided on the hinge sleeve 47. A T-shaped rod 49 is rotatably connected to the U-shaped seat 481. The T-shaped rod 49 is slidably connected to the concave seat 52. Under normal conditions, under the elastic force of the return spring 471, the elliptical sealing plate 46 connected to the L-shaped block 48 presses against the discharge cut at the bottom end of the discharge pipe 42, preventing discharge from the bottom end of the discharge pipe 42. When the T-shaped rod 49 moves down and touches the concave seat 52, the L-shaped block 48 rotates along the hinge sleeve 47 and overcomes the elastic resistance of the return spring 471, causing the elliptical sealing plate 46 to rotate and flip open, thereby allowing the fertilizer in the discharge pipe 42 to fall out.

[0035] Reference Figure 3 and Figure 4 The concave seat 52 has a strip guide groove 522. The T-shaped rod 49 is slidably installed along the strip guide groove 522. A round stop block is fixed at the upper end of the T-shaped rod 49, and the round stop block is larger than the strip guide groove 522. During the rotation of the L-shaped block 48 along the hinge sleeve 47, the T-shaped rod 49 can be slidably installed along the strip guide groove 522. When the round stop block at the upper end of the T-shaped rod 49 touches the concave seat 52, the elliptical sealing plate 46 is forced to passively rotate and flip open.

[0036] Reference Figure 3 and Figure 4 The concave seat 52 is also provided with a sliding groove 521. A motor 51 is fixedly installed on the upper surface of the concave seat 52. The output end of the motor 51 is connected to a lead screw 53. The lead screw 53 is rotatably connected to the concave seat 52 and threadedly connected to the slide 54. The slide 54 is slidably installed along the sliding groove 521. The motor 51 is started by the electric control switch 3. The output end of the motor 51 drives the lead screw 53 to rotate, causing the slide 54 to slide along the sliding groove 521 of the concave seat 52. This drives the volute 43 and the discharge pipe 42 to move together, so that the discharge pipe 42 can be inserted into the soil or pulled out of the soil.

[0037] Working principle: In use, an appropriate amount of fertilizer is loaded into the fertilizer box 2. The handcart 1 is pushed to the planting area of ​​the black chokeberry that needs fertilization. By operating the electric control switch 3, the motor 51 rotates in the forward direction, driving the lead screw 53 to rotate. This causes the slide 54 to slide down the concave seat 52 along the volute 43. The distributing plate 44 inside the volute 43 is fixedly connected to the gear 45 by a shaft. Because the gear 45 meshes with the rack 55, the distributing plate 44 rotates passively. Thus, the fertilizer in the fertilizer box 2 enters the inner cavity of the volute 43 through the corrugated pipe 41 connected to the bottom, and then is conveyed to the discharge pipe 42 through the multiple arc grooves 441 on the distributing plate 44. At the same time, the volute 43 drives the discharge pipe 42 to insert into the black chokeberry. The soil around the roots of the ribbed chokeberry is fertilized. The discharge pipe 42 moves downward along with the T-shaped rod 49 via the hinge sleeve 47 and the L-shaped block 48. When the discharge pipe 42 is inserted to a certain depth, the upper end of the T-shaped rod 49 is limited by the concave seat 52, which forces the elliptical sealing plate 46 at the oblique cut at the bottom of the discharge pipe 42 to rotate and open, allowing fertilizer to be discharged smoothly from the discharge pipe 42 into the soil, thus completing the fertilization operation for one black chokeberry. After one fertilization is completed, the motor 51 rotates in the opposite direction, causing the discharge pipe 42 to be pulled out of the soil. At this time, the elliptical sealing plate 46 quickly rotates and resets under the action of the return spring 471, closing the opening at the bottom of the discharge pipe 42 to prevent fertilizer leakage. If the next fertilization is required, the above steps can be repeated.
