Problems solved by technology

However, in actual work, because tractor drivers are used to using mechanical seeders, they do not have a strong sense of compliance with the operating procedures for using pneumatic seeders, and it often happens that the fan starts to move forward without starting or just starting the operation

Embodiment approach 1

[0047] Such as figure 1 with figure 2 Shown is a front sectional view and a right sectional view of the overall structure of the anti-knock device of Embodiment 1. Wherein, the anti-knocking seed pushing sheet is a circular anti-knocking seed pushing sheet 3 with pushing ears 301 distributed on the circumference, and the pushing part is the pushing ears 301.

[0048] The control mechanism is a needle-type cylinder 12, which is fixed on the lower casing 4 of the seed meter by a cylinder fixing frame 11 through bolts, and the cylinder action point connecting frame 13 extends the cylinder of the needle-type cylinder 12 to a rod 1201 It is connected with the round anti-knocking seed pushing piece 3 to realize the linkage between the needle-shaped cylinder 12 and the circular anti-knocking seed pushing piece 3; The air inlet 1 is connected.

[0049] The anti-knocking device is installed at a certain position before the seed clearing area II, and in the working state, such as ...

Embodiment approach 2

[0053] Such as Figure 5 As shown, it is a perspective view of the working state of the anti-knocking device of the second embodiment. Wherein, the anti-knocking seed pushing sheet is a circular anti-knocking seed pushing sheet 3 with pushing ears 301 distributed on the circumference, and the pushing part is the pushing ears 301.

[0054] The control mechanism is the pusher arm 16, the circular anti-knocking seed pusher 3 is hinged to one end of the pusher arm 16, and the other end of the pusher arm 16 is hinged to the lower housing 4 of the seed meter. and can rotate around point A; the torsion spring 17 is sandwiched between the seed push arm 16 and the torsion spring limit sleeve 18, and pushes the seed push arm 16 toward the outer edge of the seed tray 5 The arm limit sleeve 15 is fixed by the position adjusting bolt 19 of the arm limit sleeve passing through the adjustment hole 14 on the lower housing 4 of the seed meter. One end of the pusher arm 16 abuts against the l...

Embodiment approach 3

[0056] Such as Figure 7 As shown, it is the working state diagram of the anti-knocking device of the third embodiment, Figure 8 for Figure 7 Schematic diagram of the installation position of the middle anti-knocking seed pushing piece on the upper housing, wherein the anti-knocking seed pushing piece is an arc-shaped anti-knocking seed pushing piece 8 with a pushing arc 801, and the pushing part is a pushing arc Tablet 801.

[0057] The control mechanism is a position adjusting nut 9. One end of the arc-shaped anti-knocking seed pushing piece 8 is movably connected to the upper housing 20 of the seed meter through a thread, and the other end is adjustablely connected to the seed meter through the position adjusting nut 9. On the oblong hole of the housing 20, changing the position of the position adjusting nut 9 on the oblong hole of the upper housing 20 of the seed metering device can determine whether the pushing arc 801 of the arc-shaped anti-knocking seed pushing shee...

Abstract

The invention relates to the technical field of agricultural machinery and particularly relates to a seed-coat-removal preventing device for an air-blowing type precision seeding apparatus. The seed-coat-removal preventing device for the air-blowing type precision seeding apparatus comprises a seeding plate (5) and a seed-coat-removal preventing seed-pushing sheet, wherein the seeding plate (5) is provided with a seed-pushing groove (502) and a molding hole (501) which are communicated with each other; the seed-coat-removal preventing seed-pushing sheet is provided with a seed-pushing part which is located in the seed-pushing groove (502) of the seeding plate (5); the seed-coat-removal preventing seed-pushing sheet is connected with a control mechanism; and under the driving of the control mechanism, the seed-pushing part enters or leaves the molding hole (501) of the seeding plate (5). In the seed-coat-removal preventing device provided by the invention, one seed-coat-removal preventing seed-pushing sheet is additionally arranged at a junction of a seed-charging area and a seed-clearing area, so that the seed-coat-removing problem caused by seeding plate rotation under a normal working condition of the seeding apparatus when the energy is absent or insufficient is solved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an anti-knocking device for an air-blowing precision seed metering device. Background technique [0002] As a pneumatic precision seed metering device, the air-blowing seed metering device has been widely used abroad, and it is also in the stage of popularization and application in China. Single-seed sowing is realized by using the principle of air-flow seed clearing, and the requirements for the shape and size of the seeds are not strict. It is especially suitable for the sowing of non-circular seeds such as corn with large variations in size and shape. Due to its better filling performance, it has strong adaptability to high-speed operation and high productivity. At the same time, it is also highly adaptable to wind pressure fluctuations, sows evenly, and is more convenient to use and adjust. It is a precision seed metering device with good prospects for popular...
