Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically, it relates to a trenching and fertilization device. Background Technology

[0002] With the continuous development of modern agriculture, the requirements for mechanization are getting higher and higher. Some regions have already achieved automation of ditching and fertilization. In my country, orchards and tea gardens cover a large area and need to be loosened and fertilized once or twice a year. At present, the machinery for loosening soil and fertilizing in orchards and tea gardens in my country is basically manual. Manual ditching, loosening soil and fertilizing is labor-intensive, has low production efficiency and high operating costs, and is not suitable for the needs of current large-scale production development. Therefore, various types of ditching and fertilizing machines have appeared on the market.

[0003] The trenching and fertilization device disclosed in CN218244384 U uses a trenching plow to open trenches, then stores fertilizer in a fertilizer hopper at the rear and discharges it through a discharge pipe. However, the main purpose of trenching is to facilitate the direct delivery of fertilizer to the roots of plants, providing sufficient nutrient supply and ensuring that the fertilizer is effectively absorbed and utilized by the plants. Since the trenching plow and the discharge pipe of this device are set up separately, it is very easy for the fertilizer to not fall into the opened fertilization trench in time, affecting the fertilizer effect. In addition, since the angle of the trenching plow cannot be adjusted, the shape and depth of the trench cannot be adjusted, resulting in poor applicability.

[0004] Based on the above problems, there is an urgent need in this field for a trenching and fertilization device that can accurately deliver fertilizer into the prepared fertilizer trench and can adjust the trenching angle as needed. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments.

Detailed Implementation

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments. The present invention provides the following embodiments.

[0041] like Figures 1-13 As shown, this embodiment provides a technical solution:

[0042] A trenching and fertilizing device includes a mounting bracket 10, a hopper assembly 20, a wheel assembly 30, a connecting frame 40, a fertilizer inlet pipe assembly 50, a trenching assembly 60, a rotating and fixing assembly 70, and a traction mechanism 80. In this embodiment:

[0043] A hopper assembly 20 is fixed to the upper end of the bracket 10. The hopper assembly 20 includes a fertilizer hopper 21, which is used to store fertilizer for fertilization. A motion wheel assembly 30 is installed on both sides of the mounting bracket 10. The motion wheel assembly 30 includes a motion wheel 31, which is rotatably installed on both sides of the mounting bracket 10. A traction mechanism 80 is fixed to the front end of the mounting bracket 10 for connecting to traction equipment.

[0044] In this embodiment, the traction device connected to the traction mechanism 80 includes agricultural equipment such as tractors. The traction device drives the entire ditching and fertilizing device and provides power. The hopper assembly 20 also includes a rotating seat 22, which is fixed to the inner wall of the fertilizer hopper 21. A rotating rod 23 is fixed inside the fertilizer hopper 21. Both ends of the rotating rod 23 are rotatably mounted on the rotating seat 22. The rotating rod 23 can rotate freely inside the rotating seat 22. Multiple sets of stirring rods 24 are evenly arranged on the surface of the rotating rod 23. When the rotating rod 23 rotates, it drives the stirring rods 24 to rotate, which stirs the fertilizer inside. On the one hand, it can break up the fertilizer inside, and on the other hand, it can make the fertilizer flow smoothly into the fertilizer inlet pipe assembly 50 at the lower end of the fertilizer hopper 21, preventing the fertilizer from accumulating inside the fertilizer hopper 21.

[0045] Furthermore, each set of stirring rods 24 includes four rods arranged in a cross shape, and the rods on adjacent stirring rods 24 are staggered, that is, the rods on adjacent stirring rods 24 are not parallel, but at a certain angle, which improves the stirring effect on fertilizer.

[0046] In this embodiment, the motion wheel assembly 30 further includes two sets of support frames 32 symmetrically arranged on the mounting bracket 10. Bearings 33 are fixed on the support frames 32, and drive rods 34 are rotatably mounted on the bearings 33. The drive rods 34 can rotate freely at the inner ring of the bearings 33. One end of the rotating rod 23 extends out of the fertilizer hopper 21 and is fixed with a transmission gear 25. The drive rod 34 is also fixed with a transmission gear 25. The two transmission gears 25 are connected by a transmission chain 26. The motion wheels 31 are installed at both ends of the drive rod 34.

[0047] During the trenching and fertilization process, the moving wheel 31 contacts the ground and rotates with the movement of the traction mechanism 80. When it rotates, it drives the drive rod 34 to rotate. The teeth of the transmission chain 26 and the two transmission gears 25 mesh to transmit power. When the drive rod 34 rotates, it transmits power through the transmission chain 26 and the transmission gears 25, which drives the rotating rod 23 to rotate and stir the fertilizer. Therefore, the stirring and crushing of fertilizer does not require additional power. Power is generated by the movement of the moving wheel 31, making it more convenient to use.

[0048] The bottom of the fertilizer hopper 21 is fixed with a rotating fixing component 70. The rotating fixing component 70 includes an inverted U-shaped fixing bracket 71. At least two sets of connecting brackets 40 are provided on the inner side of the fixing bracket 71. A ditching component 60 is fixed at the lower part of the connecting bracket 40. The number of connecting brackets 40 is the same as the number of ditching components 60 and fertilizer inlet pipe components 50. A ditching component 60 is installed at the bottom of each connecting bracket 40, and a fertilizer inlet pipe component 50 is installed on each ditching component 60.

[0049] The connecting frame 40 includes an upper support 41 and a lower support 42. The upper end of the upper support 41 is fixed to the bottom of the fertilizer hopper 21, and the lower end is hinged to the upper end of the lower support 42. The upper support 41 and the lower support 42 are hinged together, so the lower support 42 can rotate around the hinge point connected to the upper support 41, adjusting the angle and thus driving the bottom trenching component 60 to adjust the angle. The lower end of the lower support 42 is fixed to the fertilizer box 63. A guide frame 43 is fixed to the front side of the lower support 42, and a traction rod 44 is fixed on the guide frame 43. All connecting frames 40 are linked by the traction rod 44. When the traction rod 44 moves, it can simultaneously drive all the lower supports 42 to rotate, ensuring that the tilt angle of the lower supports 42 in all connecting frames 40 is consistent when they are adjusted.

[0050] The bottom of both sides of the fixed bracket 71 is provided with hollowed-out arc-shaped rotating grooves 72. Positioning blocks 73 are fixed on both sides of the arc-shaped rotating grooves 72. Multiple sets of positioning slots 74 are evenly arranged on the outer side of the positioning blocks 73. The two ends of the traction rod 44 pass through the arc-shaped rotating grooves 72. The traction rod 44 can rotate within the arc-shaped rotating grooves 72 to adjust the tilt angle of the lower bracket 42.

[0051] A locking block 75 is fitted onto the traction rod 44 on the outer side of the fixed bracket 71. A locking block 76 is fixed inside the locking block 75 and is engaged in the positioning slot 74. A locking spring 77 is fitted onto the traction rod 44 on the outer side of the locking block 75. One end of the locking spring 77 abuts against the outer surface of the locking block 75, and the other end is fixed to the traction rod 44. Under normal conditions, the locking spring 77 applies elastic force to the locking block 75, allowing the locking block 76 to be firmly engaged in the positioning slot 74. Inside, the traction rod 44 is prevented from moving within the arc-shaped groove 72, thus fixing the tilt angle of the lower bracket 42. When the traction rod 44 needs to be adjusted, the locking block 75 is pushed outward to allow the locking block 76 to leave the positioning groove 74. At this time, the traction rod 44 can rotate within the arc-shaped groove 72 to adjust the tilt angle of the lower bracket 42. After adjustment, the locking block 75 is released, the pressure of the locking spring 77 is released, and the locking block 76 is re-locked into the positioning groove 74 at the new angle.

[0052] The rotation center of the arc-shaped rotating groove 72, the hinge center of the upper support 41 and the lower support 42 are all located on the same horizontal line to avoid interference in movement.

[0053] The trenching component 60 includes a trenching shovel 61, which is triangular pyramidal in shape with one vertex facing forward and the upper surface being an inclined surface facing forward. The trenching shovel 61 is used to open fertilizer trenches. A fertilizer box 63 with a hollow center is fixed to the rear end of the trenching shovel 61. The bottom of the fertilizer box 63 is provided with a hollow fertilizer inlet 64. The trenching shovel 61 and the fertilizer box 63 adopt an integrated design. After the trenching shovel 61 has opened the fertilizer trench at the front, the fertilizer box 63 immediately sprinkles fertilizer into the fertilizer trench through the fertilizer inlet 64. The fertilizer falls right into the trench, making it less likely for the fertilizer to fall outside the trench, allowing the fertilizer to be transported to the roots of the plants to the maximum extent and reducing fertilizer loss and waste.

[0054] In this embodiment, the height of the fertilizer inlet 64 is higher than the bottom of the trenching shovel 61. The fertilizer inlet 64 does not contact the soil, reducing local blockage, resulting in good fertilization effect, high reliability, and low discharge resistance.

[0055] In this embodiment, a soil dividing plate 62 is fixed to the upper end face of the trenching shovel 61. The soil dividing plate 62 includes three plates arranged in a Y shape, with one plate facing the front of the trenching shovel 61. The soil dividing plate 62 distributes the soil divided by the trenching shovel 61 to both sides of the trenching shovel 61, avoiding accumulation on the trenching shovel 61 and affecting normal trenching.

[0056] The upper end of the fertilizer box 63 is fixed with a bendable fertilizer inlet pipe assembly 50. Since the angle of the connecting frame 40 in this embodiment can be adjusted, the fertilizer inlet pipe assembly 50 also needs to be bent accordingly. The upper and lower ends of the fertilizer inlet pipe assembly 50 are respectively connected to the fertilizer hopper 21 and the fertilizer box 63. The fertilizer is stored through the fertilizer hopper 21 and falls naturally into the fertilizer inlet pipe assembly 50 during stirring. Then it enters the fertilizer box 63 along the fertilizer pipe assembly 50 and flows out from the fertilizer outlet 64 for fertilization.

[0057] In this embodiment, the fertilizer inlet pipe assembly 50 includes an outlet pipe 51 and an inlet pipe 52. The bottom of the outlet pipe 51 is connected to the inside of the fertilizer box 63. A cylindrical adjusting cylinder 54 is fixed to the upper end of the outlet pipe 51. An inlet 56 is provided at the upper end of the adjusting cylinder 54. The side of the adjusting cylinder 54 is hollowed out and a rotating frame 55 is fixed thereon. The upper end of the inlet pipe 52 is connected to the inside of the fertilizer hopper 21. The lower end is semi-circular. A rotating groove 53 is provided at the bottom of the inlet pipe 52. The adjusting cylinder 54 is stuck at the bottom of the inlet pipe 52, and the outlet pipe 51 passes through the rotating groove 53. The rotating frame 55 is rotatably connected to the side of the inlet pipe 52. A hinge rod is provided on the side of the rotating frame 55. The hinge rod passes through the side wall of the inlet pipe 52.

[0058] The regulating cylinder 54 can rotate at the bottom of the feed pipe 52, and the discharge pipe 51 moves in the rotating groove 53 accordingly. The angle between the discharge pipe 51 and the feed pipe 52 can rotate with the rotation of the connecting frame 40. When the fertilizer inlet pipe assembly 50 is conveying fertilizer, the waste material enters the feed pipe 52 from the fertilizer hopper 21, and then enters the regulating cylinder 54 through the feed port 56. It then enters the discharge pipe 51 through the regulating cylinder 54, and the discharge pipe 51 conveys the fertilizer to the fertilizer box 63.

[0059] This embodiment employs the aforementioned structure of the fertilizer inlet pipe assembly 50, ensuring that the outlet pipe 51 and the inlet pipe 52 can be constructed of rigid materials. In the prior art, flexible hoses often have reduced cross-sectional area at the bend, affecting fertilizer delivery. Therefore, the aforementioned bending structure is used to ensure that the cross-sections of the outlet pipe 51 and the inlet pipe 52 do not shrink during bending, thus avoiding impact on fertilizer delivery. The rotating shaft connecting the rotating frame 55 and the inlet pipe 52 is located on the same horizontal line as the hinge center of the upper support 41 and the lower support 42, effectively preventing motion interference.

[0060] The upper end of the feed pipe 52 is fixed with a corrugated pipe 57. The upper end of the corrugated pipe 57 is fixed to the bottom of the fertilizer hopper 21. The corrugated pipe 57 is connected to the feed pipe 52 and the inside of the fertilizer hopper 21. The corrugated pipe 57 will not bend, so it will not affect the delivery of fertilizer. However, the corrugated pipe 57 can play a good buffering role.

[0061] In this embodiment, each fertilizer box 63 is provided with two sets of upper supports 41 and lower supports 42 symmetrically arranged at its upper end. The discharge pipe 51 is located between the two lower supports 42, and the corrugated pipe 57 and the feed pipe 52 are located between the two upper supports 41. The upper supports 41 and lower supports 42 play a protective role for the fertilizer inlet pipe assembly 50.

[0062] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted herein.
