Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a small-sized seed drill that can be used in hilly areas. Background Art

[0002] Hilly areas have complex terrain, steep slopes, rugged ground and variable soil conditions. Traditional seed drills face significant challenges in such environments. The technical defects of existing hilly seed drills are mainly reflected in the following aspects:

[0003] 1) Insufficient terrain adaptability. Existing seeders are mostly designed for flat farmland and lack optimization for hilly terrain. When operating on slopes or uneven ground, the seeding tube is a fixed design and cannot adapt to terrain changes. The seed delivery stability is poor during bumps. The rigidly connected traditional seeding system is easily disturbed by vibration, resulting in uneven seed distribution, serious leakage or accumulation. 2) Bulky structure and poor maneuverability. In order to enhance stability, existing equipment uses heavy frames or complex transmission structures, resulting in a large weight of the whole machine, making it difficult to flexibly turn on narrow slopes, and the transportation cost is high, which is difficult for small farmers to afford. 3) Single function and low efficiency. Most seeders only complete the sowing operation and do not integrate the irrigation system. Additional equipment or manual work is still required to complete water replenishment, watering, and soil covering operations, which increases time cost and labor intensity. 4) Row spacing adjustment is cumbersome. In the existing technology, row spacing adjustment mostly relies on manual disassembly and reorganization of components, which is time-consuming and low-precision, and it is difficult to meet the planting needs of diversified crops in hilly areas. 5) The bumpy hilly terrain can easily lead to inconsistent sowing depths, lack of elastic buffer structures, and unstable soil pressure after sowing, which affects the emergence rate.

[0004] Therefore, it is an urgent problem to provide a hill seeder that is accurate, stable, simple and easy to operate. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a small-sized seed drill that can be used in hilly areas, comprising an upper frame and a connecting plate, wherein the upper frame and the connecting plate are fixedly connected, a seed box, a driving assembly and a seeding assembly are installed on the upper frame, a feed port is provided on the seed box, a seeding channel is provided inside the seed box, a seeding device is installed at the seeding channel, the driving assembly passes through the seed box, and the seeding device is installed on the driving assembly;

[0006] The seeding assembly includes a mounting frame, a guide block, an inner feed pipe, an outer feed pipe, an auxiliary wheel, a guide rail and an elastic tube. The inner feed pipe is fixedly connected to the mounting frame, the inner feed pipe is communicated with the seeding channel through the elastic tube, the outer feed pipe is sleeved on the inner feed pipe, the outer wall of the inner feed pipe is in contact with the inner wall of the outer feed pipe, the outer feed pipe is connected to the mounting frame through an elastic member, the auxiliary wheel and the outer feed pipe are movably connected, the guide block is sleeved on the guide rail, the guide block is provided with a limiting hole, the guide rail is provided with a plurality of sockets, the limiting hole corresponds to the socket, the pins are placed in the limiting hole and the socket at the same time, the guide rail is installed on the upper frame, and the guide block is fixedly connected to the mounting frame.

[0007] Preferably, it also includes a lower frame, which is fixedly connected to the connecting plate, and is equipped with a water tank, a water pump, a main pipe and a suppressing wheel assembly. The water tank is provided with a water inlet, the water pump inlet is connected to the water tank, the water pump outlet is connected to the main pipe, a plurality of nozzles are installed on the main pipe, the nozzle outlets face the ground, and the main pipe is fixed on the lower frame.

[0008] Preferably, the pressing wheel assembly comprises a pressing wheel, a shaft body and a connecting column, the pressing wheel is fixed on the shaft body, the connecting column is sleeved on the shaft body, and the connecting column is fixed on the lower surface of the lower frame.

[0009] Preferably, the upper frame is fixedly connected to the lower frame via a bracket.

[0010] Preferably, a connecting frame and walking wheels are installed on the connecting plate, and the connecting frame is externally connected to a traction device.

[0011] Preferably, walking wheels are installed on the connecting plate.

[0012] Preferably, the driving assembly includes a motor and a driving shaft, the driving shaft is connected to the output end of the motor, the driving shaft is installed on the upper frame, the driving shaft passes through the seed box, and the seed meter is fixedly connected to the driving shaft.

[0013] Preferably, the elastic tube is a spring hose.

[0014] Preferably, the elastic member is a spring.

[0015] Preferably, the guide rail is mounted on the upper frame through a guide rail mounting seat.

[0016] The present invention has the following advantages:

[0017] (1) The present invention adopts an elastic tube (spring hose) connected with a spring. The seeding assembly is connected to the seed box through the spring hose. The external feed pipe is connected to the mounting frame through a spring. When the ground is uneven, the spring can be retracted to buffer vibration. The external feed pipe can adaptively adjust the height according to the terrain to ensure continuous and stable seed transportation. The guide block and the guide rail are limited by a latch. When the auxiliary wheel contacts the ground, it can slide with the terrain, further reducing the impact of vibration on seeding accuracy and avoiding the problem of rigid connection of the traditional seeding pipe and easy blockage or scattering of seeds during bumps.

[0018] (2) The present invention adopts a split frame, in which the upper frame (seed box, drive assembly) and the lower frame (water tank, pressure wheel) are combined by connecting plates and brackets, which not only ensures strength but also reduces the weight of each part, making it easy to disassemble and transport. The connecting frame is connected to an external traction device and is equipped with walking wheels to achieve flexible steering, adapting to narrow slopes, thus solving the problem that the heavy structure of existing seed drills limits their maneuverability on hills.

[0019] (3) The present invention integrates a sprinkler irrigation system, in which the lower frame is equipped with a water tank, a water pump and a sprinkler head. Water is evenly sprayed through the main pipe during sowing, realizing "sowing and irrigation" and reducing soil moisture loss. The pressing wheel assembly is connected to the connecting column through an axle to ensure uniform soil coverage and improve the contact tightness between seeds and soil, thus solving the problem that the existing seeding machine has a single function and requires the cooperation of multiple devices.

[0020] (4) The present invention sets the guide block on the guide rail with a socket, and the sliding mounting frame can be pulled out by pulling out the pin, and the spacing between the inner feed tubes can be adjusted and then re-fixed. This design can complete the switching of multiple ridge spacings in a short time, adapting to the needs of different crops such as corn and wheat, and solving the problem that the existing planter row spacing adjustment relies on complex mechanical reorganization.
