Description

Technical Field

[0001] The invention relates to the technical field of fertilizer spreaders, in particular to a furrowing fertilizer spreader for an orchard. Background Art

[0002] Furrow fertilization is a common fertilization method in orchard management. Fertilizer is buried in the soil, which can be better mixed with the soil, enhance the contact between the root system and fertilizer, and improve the effective utilization rate of nutrients. Compared with ground fertilization, trench fertilization can deliver nutrients to the root system more effectively.

[0003] Current trenching fertilizer spreaders are usually divided into rotary tillage and furrow opener types. In orchards, rotary tillage fertilizer spreaders are often used. The rotating blades can effectively loosen the soil, improve soil permeability and drainage, help improve the root growth environment, and cut off the roots extending from fruit trees, reducing resistance during the trenching process.

[0004] However, the existing rotary tillage ditching and fertilizing machines still have the following shortcomings in the process of ditching and fertilizing in orchards: Although the cutter can cut through the intertwined roots of fruit trees during the rotary trenching process, since the main purpose of the cutter is to trench and loosen the soil, its sharpness is often not enough to form a neat wound surface, resulting in a larger wound surface on the plant's root system during the trenching process, and there is pulling when the plant's root system is cut, which makes it more difficult to repair the plant's root system and affects the growth of the fruit trees.

[0027] Furrowing fertilization is a commonly used fertilization method in orchard management. However, in the process of furrowing and fertilizing in orchards, the existing rotary tillage fertilization machine can cut off the intertwined roots of fruit trees when the cutter rotates to open furrows. However, since the main purpose of the cutter is to open furrows and loosen the soil, its sharpness often cannot form a neat wound surface, resulting in a large area of ​​wound surface on the root system of the plant during the furrowing process, and there is a pulling situation when the root system of the plant is cut, which makes it more difficult to repair the root system of the plant, affecting the growth of the fruit tree.

[0028] When the trenching fertilizer spreading machine provided by the present invention is used: The connecting frame 14 is installed with the tail end of the tractor, and the transmission shaft 12 is connected to the output end of the tail of the tractor through a universal joint. This connection method is an existing transmission connection method. When fertilizing by ditching, the direction of the cutting mechanism 13 is the traveling direction, the transmission 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, and the ditching disc 10 drives the ditching cutter 11 to rotate, thereby achieving the purpose of rotary tillage and ditching. During the traveling process, the soil produced by rotary tillage and ditching will accumulate on both sides of the fertilizer ditch under the guidance of the scraper plate 7 and the soil guide plate 8; Before the furrowing assembly rotates to till the soil, the transmission shaft 12 cooperates with the transmission assembly through the bevel gear 43 to simultaneously drive the two sets of cutting mechanisms 13 to move, so that the cutting mechanisms 13 can neatly cut the supporting roots on both sides of the fertilizer furrow before the furrowing assembly rotates to till the soil, thereby avoiding the problem of pulling and irregular wound surface caused by insufficient sharpness of the furrowing tool 11 when cutting the roots of the plants, effectively reducing the degree of damage to the plants and facilitating the repair of the plants; and the liquid supply assembly continuously guides the repair liquid to the two sets of cutting mechanisms 13, and can apply medicine to the cutting position of the cutting mechanism 13, further promoting the healing and regeneration of the roots.

[0029] Specifically, the rotation of the transmission shaft 12 drives the transmission shaft 2 40 to rotate via the bevel gear 43 and the bevel gear 3 42, the rotation of the transmission shaft 2 40 drives the rotating shaft 27 to rotate via the bevel gear 2 39 and the bevel gear 1 38, the rotation of the rotating shaft 27 drives the two discs 29 to rotate, the rotation of the disc 29 drives the slide bar 24 to reciprocate and slide in the slide groove 34 via the boss 2 30, the connecting rod 25 and the boss 1 26, the slide bar 24 drives the movable knife 36 to cooperate with the fixed knife 37 to perform a reciprocating cutting action via the U-shaped connecting plate 35, so that the root system will be neatly cut off after entering between the fixed knife 37 and the movable knife 36.

[0030] In the liquid supply assembly, the repair liquid is stored in the liquid storage tank 15. The liquid pump in the liquid storage tank 15 guides the repair liquid to the two conduits 1 31 through the conduit 2 33 and the three-way pipe joint 32. The conduit 1 31 guides the repair liquid to the cavity 46. The repair liquid in the cavity 46 adheres to the side of the fertilizer ditch through the spray hole 47, thereby realizing the drug application treatment of the broken roots.

[0031] After the furrowing assembly has rotary tilled and furrowed, the fertilizing mechanism directs the fertilizer into the formed fertilizer furrow, thereby completing the fertilizing operation.

[0032] Therefore, in the present invention, by cooperating with the liquid supply component, the transmission component and the cutting mechanism 13, the root system of the fruit tree can be neatly cut off before rotary tillage, furrowing and fertilization, and a repair liquid can be sprayed on the wound surface; by cutting off the root system in advance, the impact force caused by the furrowing tool 11 in the subsequent rotary tillage operation can be significantly reduced; neat cutting can make the wound surface more regular, reduce the trauma caused by unevenness, thereby avoiding the formation of large wounds and irregular wounds, and relative to the pulling-type cutting of the furrowing tool, neat cutting can reduce the overall damage to the root system and 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, contributing to the rapid growth of new roots, improving the expansion and depth of the root system, and providing better conditions for fruit trees to absorb nutrients; and by spraying the repair liquid while cutting, the necessary nutrition and protection can be provided to the incision, promoting the healing and regeneration of the root system.

[0033] Embodiment 2: See also Fig.10 On the basis of Example 1, a cone 44 is fixedly installed at the bottom end of the strip 22. The arrangement of the cone 44 can improve the smoothness of the strip 22 when inserted into the soil.

In this embodiment, the elastic telescopic cover 45 is provided to avoid the situation in which soil enters 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 reciprocating lifting and lowering sliding of the slide bar 24 in the slide groove 34.

[0035] Embodiment 4: See also Fig.12 On the basis of Example 2, a protective cone 48 fixedly connected to the strip plate 22 is provided between two adjacent fixed knives 37, and the protective cone 48 is vertically arranged between the strip plate 22; In this embodiment, a comb tooth structure is formed on the side of the slat 22 by setting a plurality of protective cones 48, which can provide certain protection for the movable blade 36 and the fixed blade 37 to prevent stones in the soil from contacting the movable blade 36 and the fixed blade 37 and causing damage; at the same time, the roots of the plants in the soil will be stuck between the two protective cones 48 at the corresponding positions, which can provide certain support and limit for the roots, so that the movable 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.
