Description

Floating support type active no-tillage anti-blocking device

technical field

The invention belongs to the technical field of agricultural machinery, and in particular relates to a floating support type active no-tillage anti-blocking device for a no-tillage seeder.

Background technique

After decades of practical research in my country, it has been shown that conservation tillage technology can reduce soil wind and water erosion, improve soil fertility and drought resistance, etc. At present, the blockage of no-tillage planters caused by large straw coverage is the difficulty and focus of conservation tillage technology. It is of great significance to design and develop an anti-blocking device for planters suitable for my country's conservation tillage technology.

At present, there are mainly two types of anti-blocking devices for no-tillage seeders in my country: passive anti-blocking devices and power-driven anti-blocking devices.

Patent No. ZL200720033098.6 is a Chinese utility model patent "spring-tooth anti-blocking device for no-tillage seeder", which shifts the straw and weeds on the seed bed to both sides to form a clean seed belt and prevents the straw and weeds from being entangled. Trench device; the support wheel anti-blocking device in the Chinese utility model patent "less tillage mulching seeder" with the patent application number 01222698. Weeds flow with the openers causing congestion ahead of the openers. These are passive anti-blocking devices with poor anti-blocking ability and are only suitable for situations where the amount of straw on the surface is small.

Chinese invention patent No. ZL200810225477.4 "active reciprocating no-tillage anti-blocking unit"; patent No. ZL03264397.7 Chinese invention patent "no-tillage seeder combined sawing anti-blocking device"; patent No. ZL200320129940. 8 "Forward rotation anti-blocking device for wheat no-tillage seeder". These power-driven anti-blocking devices are mainly used in areas with a large amount of straw in the double-cropping area of North China. However, the rotating speed of the cutter shaft of these driving anti-blocking devices is high, the vibration and noise of the machine are large, and the safety performance is poor; After being thrown up by the high-speed rotating cutter, it is easy to fall on the seed belt, causing blockage in front of the opener.

Detailed ways

The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings.

As shown in FIGS. 1-5 , the floating support type active no-tillage anti-blocking device of the present invention includes a gearbox, a frame 10 , an active blockage removal device 1 and a floating support device 2 . It should be noted that, in the present invention, the forward direction of the device is taken as the front end.

Wherein, as shown in FIG. 2 , the active blockage removal device 1 includes a knife shaft 15 with a knife seat 14 and an active blockage removal cut 12 . Wherein, cutter shaft 15 is connected with gearbox, and its two ends are connected with the bearing block 18 that is fixed on the frame 10 by the 3rd bolt 19 through bearing 16, and cutter shaft 15 and bearing 16 outer sides are provided with bearing end cover 17. Active block removal and cutting 12 is installed on the knife seat 14 by second bolt 13, and in order to facilitate cutting, active block removal and cutting 12 is a straight knife type cutter.

When working, the power output by the tractor is transmitted to the cutter shaft 15 through the gearbox, thereby driving the active blocking and cutting 12 to rotate. Generally, the rotating speed of the active blocking and cutting 12 is 350r/min.

As shown in Figures 1 and 3-5, the floating support device 2 is located on both sides of the active blockage removal device 1, and includes an elastic support plate 3, a spring 5, an adjustment rod 6, a flap 7 and a fixed plate 8.

Among them, the elastic support plate 3 has an arc-shaped cross-section at the front end, and has a certain angle θ with the horizontal plane of 10°-20°, on which a pin-hole shaft 3001 is fixed by welding, and the pin-hole shaft 3001 passes through the pin shaft 11 is installed on the front end of the frame 10, and the rear end is a flat plate on which a holder 3002 is fixed by welding.

The fixing plate 8 is fixed on the rear end of the frame 10 through the first bolt 9 and is provided with holes.

work process:

During operation, the floating support type active no-tillage anti-blocking device of the present invention is installed at the rear of the tractor. On the one hand, when the tractor is moving, it drives the floating support device 2 to move forward together. According to the fluctuation of the ground surface, under the adjustment of the spring 5, Make the adjustment rod 6 slide up and down in the center hole of the flap 7, thereby adjusting the position of the elastic support plate 3 and the ground, adapting to the unevenness of the ground, and playing a good supporting effect. At the same time, under the preload of the spring 5, the elastic The support plate 3 will not break away from the ground, thereby pressing down sundries such as stalks and stubble, and because the spring support plate 3 works, it will cause the fixed seat 3002 hinged with the bottom end of the adjustment rod 6 to move back and forth, so in order to facilitate the adjustment of the adjustment rod 6 Sliding up and down, the cylindrical rods at both ends of the flap 7 can also rotate in the holes of the fixed plate 8, so that the flap 7 can rotate with the top of the adjustment rod 6; on the other hand, the power output by the tractor is transmitted through the gearbox Give knife shaft 15, drive and actively remove blocking cutting knife 12 and rotate, cut off sundries such as stalks that are pushed down by spring support plate 3, stubble. Moreover, when the active blocking cutter 12 completes the cutting, the floating support device 2 still presses the straw, root stubble and weeds, which can prevent the straw, root stubble, etc. Clean and effectively prevent clogging.

The invention can form a no-tillage seeder with a fertilization ditch opener, a seed fertilizer box and a seeding suppression mechanism, and is suitable for sowing wheat and corn.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present invention can easily think of changes or Replacement should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
