Description

Technical Field

[0001] This invention belongs to agricultural machinery and mainly relates to an integrated sowing and fertilization device suitable for zero-speed hole sowing and fertilization of potatoes. Background Technology

[0002] Potatoes are propagated using tuber planting. Currently, most potato planters on the market lack the ability to apply fertilizer simultaneously, requiring an additional basal fertilizer application step. Furthermore, planting is typically done by creating furrows in the field and then sowing the potato tubers in rows. However, due to the elasticity and spherical shape of potato tubers, existing potato planters experience bouncing upon landing, resulting in poor stability in plant spacing and planting depth, thus affecting potato yield. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the prior art and, in combination with the actual needs of potato zero-speed seeding and simultaneous fertilization operations, to develop and design a new structure for potato zero-speed hole-planting and fertilization device. This device aims to adapt to and meet the needs of potato zero-speed hole-planting operations and liquid fertilizer application, achieve high hole-planting accuracy and quality, and increase potato yield.

[0004] The objective of this invention is achieved as follows: a rotary crank, a fixing pin, and a double-bar connecting rod are respectively installed on the front side of the mounting plate; a power input sprocket is installed on the back side of the mounting plate at a position coaxial with the rotary crank, and a precision metering pump is fixed to the mounting plate below the power input sprocket by an angle steel; a double-bar rocker arm is hung on the rotary crank by a slotted plate hinge, and the aforementioned fixing pin passes through the slot of the slotted plate; one end of the double-bar rocker arm is rotatably hinged to the aforementioned double-bar connecting rod by a trapezoidal connecting plate; a seeder mounting base is hinged to the other end of the double-bar rocker arm; and seeder plates I and II are respectively symmetrically and relatively swingable suspended from the lower part of the seeder mounting base by seeder plate connecting rods. Seeder plates I and II are either closed or open to each other, and the upper opposite ends of seeder plates I and II are respectively... The device is connected to a Z-shaped lifting lever via a hinged lifting rod. The middle part of the Z-shaped lifting lever is rotatably hinged to the lifting lever base, which is fixedly mounted on the seeder mounting base. Two Z-shaped lifting levers are respectively hinged to both ends of the push rod seat. A roller push rod is fixedly mounted on the push rod seat and forms a cylindrical cam mechanism with a cylindrical cam coaxially connected inside the push rod seat. The bottom end of the cylindrical cam is keyed to the output shaft of the motor fixedly mounted inside the seeder mounting base. One end of the liquid fertilizer tube is respectively connected to the liquid fertilizer nozzles fixedly mounted inside seeder plate I and seeder plate II. The tube body is installed in the grooves on the inner walls of seeder plate I and seeder plate II, and then the two tubes are combined into a single tube, which passes through the hole on the upper surface of the seeder mounting plate and connects to the outlet of the precision metering pump. The seeding cylinder is fixedly mounted at the central through hole of the seeder mounting base, thus constituting the potato zero-speed seeder fertilization device.

[0005] This invention has created and realized the operation of simultaneous fertilization during zero-speed hole planting of potatoes, combining the application of base fertilizer with the planting operation into one process. While simplifying the operation, it has greatly improved the quality and effect of potato planting. It also features a novel, unique, and reasonable structure, high quality, reliable use, and few malfunctions, providing technical support for realizing simultaneous fertilization during zero-speed hole planting of potatoes.

[0013] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. A potato zero-speed hole-planting fertilization device includes a rotary crank 17, a fixing pin 14, and a double-bar connecting rod 12 mounted on the front side of a mounting plate 15; a power input sprocket 18 is mounted on the back side of the mounting plate 15 at a position coaxial with the rotary crank 17; a precision metering pump 16 is fixed to the mounting plate 15 below the power input sprocket 18 via angle steel; a double-bar rocker arm 10 is hinged to the rotary crank 17 via a slotted plate 13, and the fixing pin 14 passes through the slotted plate 13. The slot 3, one end of the double-rod rocker arm 10 is rotatably hinged to the double-rod connecting rod 12 via a trapezoidal connecting plate 11, and the other end of the double-rod rocker arm 10 is hinged to the seeder mounting base 4. The seeder mounting base 4 is symmetrically suspended from the lower part of the seeder mounting base 4 via seeder plate connecting rods 5, and the seeder plates I8 and II9 are respectively suspended and can swing relative to each other. The seeder plates I8 and II9 are either closed or open to each other. The upper opposite ends of the seeder plate II 9 are respectively connected to the Z-shaped lifting lever 3 via hinged lifting rods 6. The middle part of the Z-shaped lifting lever 3 is rotatably hinged to the lifting lever base 2. The lifting lever base 2 is fixedly mounted on the seeder mounting base 4. The two Z-shaped lifting levers 3 are respectively hinged to both ends of the push rod seat 19. The roller push rod 21 is fixedly mounted on the push rod seat 19 and forms a cylindrical cam mechanism with the cylindrical cam 22 coaxially connected inside the push rod seat 19. The bottom of the cylindrical cam 22... One end is keyed to the output shaft of the motor 23 fixed inside the seeder mounting base 4; one end of the liquid fertilizer pipe 7 is connected to the liquid fertilizer nozzle 20 fixed inside the seeder plate I 8 and seeder plate II 9 respectively, the pipe body of the liquid fertilizer pipe 7 is installed in the groove of the inner wall of the seeder plate I 8 and seeder plate II 9, and then the two pipes are combined into a single pipe, which passes through the hole on the upper surface of the seeder mounting plate 4 and is connected to the outlet of the precision metering pump 16; the inoculation cylinder 1 is fixed at the central through hole of the seeder mounting base 4.

[0014] During operation, the external rotational power is transmitted through the power input sprocket 18 to drive the rotary crank 17 to rotate. The rotary crank 17 drives the slot plate 13 to swing around the fixed pin 14. Under the coordinated control of the slot plate 13, the double-rod connecting rod 12, the trapezoidal connecting plate 11, and the double-rod rocker arm 10, the planter mounting base 4 and its upper components rotate. When the inoculation cylinder 1 follows the planter mounting base 4 to the maximum position of the cycle, the inoculation cylinder 1 receives a seed potato. At this time, the cylindrical cam 22 is at rest under the action of the motor 23, and the roller push rod 21 remains stationary at the high point of the cylindrical cam 22. The planter plates I 8 and II 9 remain closed, and the seed potato falls into the planter plates I 8 and II 9 and is carried by them. When the planter plates I 8 and II 9 follow the planter mounting base... When the 4-cycle motion reaches the lowest position and is inserted into the seedbed soil, the cylindrical cam 22 rotates under the action of the motor 23, pushing the roller push rod 21 to move downward, thereby driving the push rod seat 19 to move downward. One end of the Z-shaped lifting lever 3, which is hinged to the push rod seat 19, moves downward, while the other end pulls the seeder plate I 8 and seeder plate II 9 upward through the lifting rod 6, causing the seeder plate I 8 and seeder plate II 9 to open, and the potato tubers fall into the soil holes. At this time, the precision metering pump 16 outputs high-pressure liquid fertilizer, which is sprayed out from the liquid fertilizer nozzle 20 through the liquid fertilizer pipe 7, completing one zero-speed seeder planting and fertilization operation for potatoes. Then, the cylindrical cam 22, which continues to rotate, drives the push rod seat 19 to move upward through the roller push rod 21, and the seeder plate I 8 and seeder plate II 9 move downward to return to the closed state. The zero-speed seeder planting and fertilization operation is carried out continuously in this cycle.
