Description

rice live broadcast machine

technical field

The utility model relates to a rice seeding device, in particular to a rice direct seeding machine.

Background technique

The existing seedling transplanting and mechanical transplanting methods cannot fundamentally solve the requirements of light and mechanized rice planting. Rice seedling throwing has the following disadvantages: first, due to low temperature, uneven sowing and other reasons, the phenomenon of empty seedlings in seedbeds often occurs; Insufficient seedlings reduce production; the third is that the discarded floppy disks for seedling cultivation are likely to cause environmental pollution. Although the rice transplanter currently being demonstrated and promoted has good mechanical performance, it is only suitable for standardized farmland that has undergone farmland transformation, and is not suitable for hilly terraced fields and deep-footed mud fields. The intensity is higher, the technology is more complicated, and it is difficult to fully promote it within a certain period of time. Only by developing characteristic small-scale live broadcast machinery and applying it to rice and rapeseed direct seeding cultivation and production will not only have a large development space, but also solve the practical problems of farming in the vast rural areas. Since various types of direct seeding machinery such as rice currently use grooved wheel sowing, it is not suitable for small hybrid rice sowing requirements, and because of its wide sowing width and inflexible steering, it is not suitable for non-standard farmland in hills and mountainous areas. It is popularized and applied in terraced fields and deep-footed mud fields. In addition, in the southern region, the weather is changeable during the planting season, especially in early spring, and there are many consecutive rains. Moreover, it is necessary to support agronomic and agricultural machinery in the links of full seedling protection, lodging, weeds, varieties, harvesting and sowing. And other key technical problems have not been solved or not completely solved, resulting in large-scale production of direct-seeding rice with high risks and low production efficiency.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a rice direct seeding machine with simple structure, small volume, convenient operation, easy maintenance and high sowing efficiency.

The purpose of this utility model is achieved through the following technical solutions:

A rice direct seeding machine, comprising a walking mechanism and a seeding device, the walking mechanism including a ground wheel, a bracket, and a main shaft; the main shaft is installed on the bracket, and the two ends of the main shaft extend out of the bracket along the center line of the main shaft and are clamped There are ground wheels;

The sowing device includes a hopper, a seeding wheel, a hair brush, and a guide plate; at least one threaded hole is provided on the circumference of the seeding wheel, and a hopper corresponding to the threaded hole is provided above the seeding wheel, A hairbrush is provided at the outlet of the hopper, the brush head of the hairbrush is in contact with the seeding wheel, and a guide plate for guiding the seeds to fall is provided below the hairbrush and wrapped around the outer circumference of the seeding wheel;

The main shaft is provided with at least one sowing device, the seeding wheel of the sowing device is installed on the main shaft, the hopper is fixed on the upper part of the frame, and the front end of the frame is provided with a mop.

In the utility model, the upper part of the frame is provided with a plurality of holes for fixing the hopper, and the hopper is fixed on the frame by screws.

In the utility model, bolts are screwed in the threaded holes provided on the circumference of the seed wheel.

In the utility model, a mud pedal is provided at the rear end of the frame.

Because the utility model adopts the above-mentioned structure, as long as the seeds are put into the hopper and the mop is pulled, the sowing can be conveniently completed. The brush on the hopper can block the redundant seeds with the rotation of the seeding wheel, and quantitatively control the quantity of sowing. The hexagon socket head screw screwed on the seed wheel can also control the amount of sowing by adjusting the depth of the hexagon socket head screw. The guide plate has a guiding function and can accurately and evenly sow the seeds to the field. The upper part of the frame There are multiple holes for fixing the hopper, so that if you want to adjust the lateral distance of the seeds, you only need to unscrew the screw and the hexagon socket screw that fix the hopper, readjust the position of the seeding device, and remove several seeding devices. Or add several seeding devices, fix the hopper in other holes with screws after adjustment, and then tighten it.

The utility model --- a rice direct seeding machine has the advantages of simple structure, small size, convenient operation, easy maintenance, high seeding efficiency, and only one person can perform the seeding operation, saving a lot of labor.
