Embodiment 1

[0025] Example 1, see Figure 1-7 , a dryland small particle seed full-film covering hole planter, including a front frame 10, a rear frame 20, a suspension device 30, a film laying assembly 40, a hole planter assembly 50 and a soil covering assembly 60; the suspension device 30 Below is provided with bulldozing board 70; Front frame 10 is equipped with suppressing roller 80, film laying assembly 40 and seeder assembly 50; 43. The flat film wheel 45 and the film opener 44 are composed; the hole seeder assembly 50 is mounted on the rear of the front frame 10 through the hole seeder draw bar 520; the rear frame 20 is equipped with a soil covering assembly 60 and a soil scraping and film pressing device 46.

[0026] The hole planter assembly 50 includes one or more hole planters 51, each hole planter 51 has a pair of hole planter traction frames 52 connected to the outer cylinder 53 through a hole planter shaft 58, a pair of inner and outer cylinder lock pins 57; The gap betwee...

Embodiment 2

[0030]Embodiment 2 is the same as Embodiment 1, except that the hole seeder 51 is different. When sowing small particles of seeds in the barren wasteland and the forage field, adjust the adjustment knob 56 with the scale 542 on the inner drum side wall 541 to 2°, corresponding to the scale 1 marked on the side walls at both ends of the outer drum 53, the seed sowing rate of 2.5-3kg / mu of small particle seeds that can meet the agronomy of the barren wasteland field can be obtained.

Embodiment 3

[0031] Embodiment 3 is the same as Embodiment 1, but the difference is that the hole sower 51, when planting small particles of seeds in the forage grass field, adjust the adjustment knob 56 with scale on the inner drum side wall 54 to 4 ° , corresponding to the scale 2 marked on the side walls at both ends of the outer cylinder 53, the sowing rate of small particle seeds that can meet the agronomy of the forage grass field is 1.5-2kg / mu.

Abstract

The invention relates to agricultural machinery, in particular to a structure of a hole seeder. A full-film-covered hole planter for small-particle seeds in dry land, including a front frame, a rear frame, a suspension device, a film laying assembly, a hole planter assembly, and a soil covering assembly; a bulldozing board is arranged under the suspension device; The frame is equipped with a pressing roller, a film laying assembly and a hole seeder assembly, and the rear frame is equipped with a soil covering assembly and a soil scraping and film pressing device. The present invention is novel in design, compact in structure and strong in adaptability. In particular, it adopts a planter assembly with precise and adjustable sowing volume and sowing depth. The inner drum realizes the adjustment of the sowing rate and changes the position of the adjusting pin on the movable mouth to control the sowing depth; the bulldozer and pressure roller are equipped to ensure the reliability of the sowing depth, improve the germination rate and sowing quality of seeds, save seeds, and improve the quality of alfalfa Working conditions for mechanized harvesting of small particles of seeds such as , onions, and Chinese herbal medicines.

Description

technical field [0001] The invention mainly relates to the technical field of seeding machines, in particular to a structure of a dry land small particle seed full film covering hole planting machine. Background technique [0002] The dryland small-particle seed full-film mulching precision sowing technology is a new technology for heat preservation, moisture conservation and drought resistance developed on the basis of traditional film mulching technology for arid and semi-arid areas. The production practice in the arid area of ​​Gansu Province has proved that the full film mulching technology can increase the yield per mu by more than 30% compared with ordinary film mulching cultivation, which has significant economic benefits. Small seeds such as alfalfa, onions, carrots, some Chinese herbal medicines, flowers and other seeds are small in size, light in weight, and shallow in depth. Northwest China is prone to wind and sand. After the full film is covered, if the soil is ...
