Description

Technical Field

[0001] This invention relates to the field of fertilizer applicator technology, specifically a trenching fertilizer applicator for orchards. Background Technology

[0002] Trench fertilization is a common method used in orchard management. By burying fertilizer in the soil, it mixes well with the soil, enhancing root contact and improving nutrient utilization. Compared to surface fertilization, trench fertilization delivers nutrients to the roots more effectively.

[0003] Currently, trenching and fertilizing machines are generally divided into rotary tiller trenching type and trencher type. In orchards, rotary tiller trenching and fertilizing machines are often used. The rotating blades can effectively loosen the soil, improve soil aeration and drainage, help improve the root growth environment, and cut off the extended roots of fruit trees, reducing the resistance during trenching.

[0004] However, existing rotary tillage ditching and fertilizing machines still have the following shortcomings in the process of ditching and fertilizing in orchards:

[0005] While the cutting tool can cut through the intertwined roots of fruit trees during the ditching process, its sharpness is often insufficient to create clean wounds because its primary purpose is to loosen the soil. This results in large wounds on the plant roots during the ditching process, and the cutting of the plant roots involves pulling, which increases the difficulty of repairing the plant roots and affects the growth of the fruit trees. Summary of the Invention

[0006] The purpose of this invention is to provide a trenching and fertilizing machine for orchards to solve the problems mentioned in the background art.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0030] The beneficial effects of this invention are:

[0031] 1. In this invention, through the coordinated arrangement of the liquid supply component, transmission component, and cutting mechanism, the root system of fruit trees can be neatly cut before rotary tillage and fertilization, and a repair liquid can be sprayed on the wound surface. By cutting the root system in advance, the impact force caused by the trenching blade during subsequent rotary tillage operations can be significantly reduced. Neat cutting makes the wound surface more regular, reducing the trauma caused by unevenness, thereby avoiding the formation of large wounds and irregular wounds. Compared with the pulling-type cutting of the trenching blade, neat cutting can reduce the overall damage to the root system and reduce subsequent growth obstacles. Moreover, the neat root wound surface can promote the root system to absorb the applied fertilizer and water more effectively, thereby improving the fertilization effect. Furthermore, by spraying the repair liquid at the same time as cutting, the cut can be provided with necessary nutrition and protection in a timely manner, promoting the healing and regeneration of the root system.

[0032] 2. By setting up an elastic telescopic cover, the present invention can prevent soil from entering between the bottom end of the slide bar and the bottom end of the slide groove during operation, thereby ensuring the stability of the slide bar as it slides back and forth in the slide groove.

[0033] 3. By setting multiple protective cones, the present invention forms a comb-like structure on the side of the strip. This structure can provide a certain degree of protection for the moving and fixed blades, preventing damage caused by contact between stones in the soil and the moving and fixed blades. At the same time, the plant roots in the soil will get stuck between the two protective cones at the corresponding positions, which can provide a certain degree of support and restraint for the roots, thereby enabling the moving and fixed blades to stably cut the roots, which is beneficial to improving the root cutting effect of the cutting mechanism.

[0065] The liquid supply assembly includes a liquid storage tank 15 fixedly installed on the top surface of the mounting platform 1. A liquid pump is installed in the liquid storage tank 15. The outlet end of the liquid pump is fixedly connected to a conduit 33. The end of the conduit 33 away from the liquid pump passes through the liquid storage tank 15 to the outside of the liquid storage tank 15 and is fixedly installed with a three-way pipe joint 32.

[0066] The ends of the two conduits 31 furthest from the strip 22 are respectively fixedly connected to the other two ends of the tee fitting 32.

[0067] Trenching fertilization is a common method in orchard management. However, in existing rotary tillage fertilization machines, although the blades can cut the intertwined roots of fruit trees during trenching, their primary purpose is to loosen the soil and therefore their sharpness is often insufficient to create clean wounds. This results in large wounds on the plant roots during trenching, and the cutting of the roots also involves pulling, increasing the difficulty of root repair and affecting the growth of the fruit trees.

[0068] The trenching and fertilizing machine provided by this invention, when in use:

[0069] The drive shaft 12 is connected to the output end of the tractor via a connecting bracket 14 and a universal joint. This connection method is the existing transmission connection method.

[0070] When ditching and fertilizing, the direction of the cutting mechanism 13 is the direction of travel. The drive shaft 12 drives the rotating shaft 9 to rotate through the bevel gear structure. The rotating shaft 9 drives the ditching disc 10 to rotate. The ditching disc 10 drives the ditching cutter 11 to rotate, thereby achieving the purpose of rotary tillage and ditching. During the process, the soil generated by rotary tillage and ditching will accumulate on both sides of the fertilizer ditch under the guidance of the scraper 7 and the guide plate 8.

[0071] Before the ditching component begins rotary tillage, the drive shaft 12, through the bevel gear 43 and the transmission component, simultaneously drives the two sets of cutting mechanisms 13. This allows the cutting mechanisms 13 to neatly cut the support roots on both sides of the ditch before the ditching component begins rotary tillage. This avoids the problems of insufficient sharpness of the ditching blades 11 when cutting plant roots, which can lead to pulling and irregular wound surfaces. This effectively reduces the degree of damage to the plant and is beneficial for plant repair. Furthermore, the liquid supply component continuously guides the repair liquid to the two sets of cutting mechanisms 13, enabling the application of medicine to the cutting positions of the cutting mechanisms 13, further promoting root healing and regeneration.

[0072] Specifically, the rotation of drive shaft 12 drives drive shaft 20 to rotate via bevel gear 43 and bevel gear 32. The rotation of drive shaft 20 drives shaft 27 to rotate via bevel gear 29 and bevel gear 38. The rotation of shaft 27 drives two discs 29 to rotate. The rotation of discs 29 drives slide bar 24 to reciprocate up and down in slide groove 34 via convex post 20, connecting rod 25 and convex post 26. Slide bar 24 drives moving blade 36 to cooperate with fixed blade 37 to perform reciprocating cutting action through U-shaped connecting plate 35. Therefore, the root system will be neatly cut after entering between fixed blade 37 and moving blade 36.

[0073] In the liquid supply assembly, the liquid storage tank 15 stores the repair liquid. The liquid pump in the liquid storage tank 15 guides the repair liquid to two conduits 31 through conduit 2 33 and three-way pipe joint 32. Conduit 31 guides the repair liquid to the cavity 46. The repair liquid in the cavity 46 adheres to the side of the fertilizer trench through the spray hole 47, thereby realizing the application of medicine to the broken roots.

[0074] After the ditching component rotary tills and opens the ditch, the fertilization mechanism guides the fertilizer into the formed fertilization ditch, thereby completing the fertilization operation.

[0075] Therefore, in this invention, by coordinating the liquid supply component, the transmission component, and the cutting mechanism 13, the fruit tree roots can be neatly cut before rotary tillage and fertilization, and a repair liquid can be sprayed on the wound surface. By cutting the roots in advance, the impact force caused by the trenching blade 11 during subsequent rotary tillage operations can be significantly reduced. Neat cutting makes the wound surface more regular, reducing the trauma caused by unevenness, thereby avoiding the formation of large wounds and irregular wounds. Compared with the pulling-type cutting of the trenching blade, neat cutting can reduce the overall damage to the root system, reduce subsequent growth obstacles, and the neat root wound surface can promote the root system to absorb the applied fertilizer and water more effectively, thereby improving the fertilization effect, helping the rapid growth of new roots, improving the expansion and depth of the root system, and providing better conditions for the fruit tree to absorb nutrients. Furthermore, by spraying the repair liquid at the same time as cutting, the cut can be provided with necessary nutrition and protection, promoting the healing and regeneration of the root system.

[0076] Example 2:

[0077] Please see Figure 10 Based on Example 1, a cone 44 is fixedly installed at the bottom end of the strip 22. The cone 44 improves the smoothness of the strip 22 when it is inserted into the soil.

[0078] Example 3:

[0079] Please see Figure 10 Based on embodiment 2, an elastic telescopic cover 45 that closes the slide groove 34 is fixedly connected between the bottom end of the slide bar 24 and the bottom end of the slide groove 34.

[0080] During the movement of the device, soil may enter between the bottom end of the slide bar 24 and the bottom end of the slide groove 34. The soil may interfere with the reciprocating sliding of the slide bar 24. In this embodiment, the elastic telescopic cover 45 is provided to prevent soil from entering between the bottom end of the slide bar 24 and the bottom end of the slide groove 34 during operation, thereby ensuring the stability of the slide bar 24 in the reciprocating sliding in the slide groove 34.

[0081] Example 4:

[0082] Please see Figure 12Based on embodiment 2, a protective cone 48 fixedly connected to the strip plate 22 is provided between two adjacent fixed blades 37, and the protective cone 48 is perpendicular to the strip plate 22.

[0083] In this embodiment, a comb-like structure is formed on the side of the strip 22 by setting multiple protective cones 48. This structure can provide a certain degree of protection for the moving blade 36 and the fixed blade 37, preventing stones in the soil from contacting the moving blade 36 and the fixed blade 37 and causing damage. At the same time, the plant roots in the soil will get stuck between the two protective cones 48 at the corresponding positions, which can provide a certain degree of support and restriction for the roots, so that the moving blade 36 and the fixed blade 37 can stably cut off the roots, which is beneficial to improving the root cutting effect of the cutting mechanism 13.

[0084] Example 4:

[0085] Please see Figure 1 and Figure 2 Based on embodiment 2, the fertilization mechanism includes a fertilizer box 2 set above the mounting platform 1. The fertilizer box 2 is funnel-shaped. A support plate 5 is fixedly connected between the side of the fertilizer box 2 and the top surface of the mounting platform 1. An integrally formed guide tube 3 is set at the bottom of the fertilizer box 2. A motor 6 is fixedly installed on one outer end face of the guide tube 3. An optical shaft 16 is rotatably installed between the two ends of the guide tube 3. The end of the optical shaft 16 near the motor 6 rotates through the end of the guide tube 3 and is fixedly connected to the output shaft end of the motor 6.

[0086] Screw blade 17 and screw blade 28, which are symmetrically distributed about the middle position of optical axis 16, are fixedly installed on the periphery of optical axis 16. The screw blade 17 and screw blade 28 have opposite rotation directions.

[0087] An inclined discharge chute 4 is fixedly connected to the side of the guide pipe 3 near the bottom. The end of the discharge chute 4 away from the guide pipe 3 is located above the scraper 7, and a gate valve is installed in the discharge chute 4 to control the opening and closing and size of the discharge chute 4.

[0088] In the fertilization mechanism, the waste in the fertilizer box 2 falls into the fertilizer ditch through the feed pipe 3 and the discharge chute 4. The motor 6 drives the optical shaft 16 to rotate, and the optical shaft 16 drives the first auger blade 17 and the second auger blade 18 to rotate, which can agitate the waste in the feed pipe 3 and has an anti-clogging function.

[0089] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
