Description

a wheat spreader

technical field

The invention belongs to the field of agricultural machinery, in particular to a wheat spreader.

Background technique

Wheat is one of the important food crops in China, especially the number one food crop in the provinces of North China. Within the theoretical framework of wheat cultivation from the beginning to the present, wheat sowing must be carried out after plowing, harrowing and other soil cultivation procedures, followed by sowing procedures such as ditching, seeding, covering soil, and suppression. The characteristics of its agronomic technology are: 1. Prepare the ground before sowing; 2. Sow the seeds directly into the soil cultivation layer to a certain depth; 3. Sow in rows with a certain distance between rows, and the seeds are concentrated and crowded in the rows. The main sowing methods are: equal row spacing narrow-width drill, wide-width drill, wide-narrow row drill, and small nest dense planting. Although these seeding methods have some advantages, such as relatively convenient management, they still have many defects compared with broadcasting. Row planting is contrary to the biological characteristics of wheat itself in many places, that is, it does not conform to the characteristics of wheat growth and development. Wheat grown in rows is concentrated in the row, and the space for plant growth is limited. It is inevitable to compete for food and drink. Especially in the critical period of wheat tillering, the performance is more obvious, the space between ridges has not been effectively utilized, and a large amount of water is evaporated, which is not conducive to moisture conservation. Although the current wheat seeders in my country are still dominated by traditional drills, the promotion of wheat spreaders is strong. Although the existing wheat combined spreaders can meet the one-time operations of rotary tillage, fertilization, sowing, and soil suppression, but There are still some criticisms, such as inconsistent sowing depth, uneven sowing, seed damage by rotary tillage, insufficient sowing soil and inconvenient subsequent intertillage management, which cannot meet the row spacing requirements of wheat sowing.

Contents of the invention

The object of the present invention is to provide a wheat spreader which can effectively improve the spreading uniformity and seeding efficiency.

In order to achieve the above object, the technical scheme adopted in the present invention is:

A wheat spreader, comprising a frame, the front end of the frame is provided with a suspension mechanism, and the frame is sequentially provided with a rotary tillage device, a soil removal device, a fertilization and seeding device, and a suppression device, and the rotary tiller is installed on the A rotary tiller at the front of the frame; the soil-removing device is a soil-removing wheel installed at the rear of the rotary tiller; the fertilizing and seeding device includes a fertilizer box installed in the middle of the frame and a fertilizing mechanism, a seed box and its lower part. The lower spreading mechanism; the suppression device includes a suppression wheel shaft and a suppression wheel installed in the rear section of the frame.

The earth-moving wheel includes a wheel shaft on which a cylindrical earth-moving wheel body is arranged, and blades are arranged on the earth-moving wheel body; the sowing mechanism includes an upper seeding pipe and a lower splitter plate, and the cross-section of the splitter plate is L-shaped. , There are a plurality of protrusions evenly distributed on the surface of the lower section of the L-shaped distribution plate.

Both sides of the lower section of the L-shaped splitter plate are provided with upward folded edges.

The power of the rotary tillage device is provided by the traction device of the spreader, and the soil pulling device and the rotary tiller device are driven by a belt; the fertilizing mechanism and the spreading mechanism are connected to the suppressing device by a chain.

The beneficial effects of the present invention are:

1. The present invention has simple structure, simple manufacturing process and low cost. The effect of the spreading mechanism on uniform seeds is good, especially when the spreading area is large, the uniform effect of seeds can be effectively guaranteed. The sowing mechanism includes an upper seed pipe and a lower diverter plate. The cross section of the diverter plate is L-shaped. There are multiple protrusions evenly distributed on the lower part of the L-shaped diverter plate. The protrusions are set to evenly seed and ensure the uniformity of wheat spreading.

2. For the wheat spreader that has been popularized at present, the soil coverage of the seeds is not enough when the rotary tiller is used to throw the soil to complete the soil covering. The present invention chooses to install the soil dial wheel between the rotary tiller and the fertilizer box to ensure the soil coverage of the seeds quantity.

Detailed ways

As shown in Figure 1, Figure 2, and Figure 3, a wheat spreader includes a frame 1, and the front end of the frame 1 is provided with a suspension mechanism 4, and the spreader is connected to the traction device (tractor) through the suspension mechanism 4, and the frame 1 Rotary tillage device 5, soil removal device 6, fertilization and seeding device, and suppression device 8 are arranged successively from front to back, and described rotary tiller device 5 is a rotary tiller installed on the front section of frame 1; described soil removal device 6 is The earth-moving wheel installed on the rear of the rotary tiller, the earth-moving wheel comprises a wheel 61, a cylindrical earth-moving wheel body 63 is arranged on the wheel shaft 61, and blades 62 are arranged on the soil-setting wheel body 63; the fertilizing and seeding device includes The fertilizer box 2 in the middle of the frame 1 and the fertilization mechanism at its lower part (the fertilization mechanism is the prior art, not shown in the figure), the seed box 3 and the spreading mechanism 7 at its lower part, and the spreading mechanism 7 includes an upper row The seed tube 71 and the diverter plate 72 at the bottom, the diverter plate cross-section is L-shaped, and a plurality of protrusions 74 are evenly distributed on the lower plate surface of the L-shaped diverter plate, so that the seeds are evenly distributed in the sowing process, and the both sides of the lower segment of the L-shaped diverter plate There is an upward flange 73, which can ensure that the seeds fall evenly on the L-shaped diverter plate, prevent the seeds from falling on the side of the diverter plate, and affect the uniformity of the seeds; the suppression device 8 includes a suppression wheel shaft installed in the rear section of the frame and Suppressing wheels (the suppressing device is prior art and will not be described in detail here). The power of the rotary tiller 5 is provided by the traction device of the spreader, and the soil pulling device 6 and the rotary tiller 5 are driven by a belt; the fertilizing mechanism and the spreading mechanism 7 are connected to the suppressing device 8 through a chain.

When the present invention works, the spreader is pulled by a tractor, and the output power of the tractor drives the rotary tiller to till the land. When a certain depth of rotary tillage is reached, the rotational power of the pressing wheel is transmitted to the fertilizing mechanism and the spreading mechanism through the multi-stage sprockets and chains. , the seeds are evenly scattered through the spreading mechanism. The soil-setting wheel is driven by the rotary tiller through the reverse transmission belt, and the soil-setting wheel rotates to bring the soft soil after rotary tillage to the highest point and throws it backwards, and covers the seeds that have been sown through the seeding pipe. In addition, the sowing depth of the seeds is adjusted by adjusting the upper and lower positions of the seeding pipes to ensure sufficient covering soil on the seeds. The invention guarantees the uniformity of seed sowing, suitable sowing depth and good sowing effect through the configuration of the earth-moving wheel, the uniform sowing of the sowing mechanism and the adjustment of the seeding pipe.
