Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to an improved fixed duckbill of a hole sowing device in a film-laying seeder. Background Art

[0002] In water-scarce regions of western my country, particularly Xinjiang, crop planting often requires mulch film to ensure adequate moisture and temperature during seedling emergence and growth. However, mulch film installation can also lead to difficulties in recycling and low recovery rates, causing white pollution that seriously contaminates the local ecological environment and impacts the soil. To address the issue of residual film recycling, extensive practical experience has shown that thicker films are easier to recycle and have higher recovery rates. Therefore, Xinjiang is gradually promoting thicker mulch films to improve recovery rates. However, thicker films also increase their strength and toughness, leading to incomplete puncturing of the existing seed drill's bill during sowing. Incomplete puncturing can cause seedlings to emerge dislocated, affecting emergence rates and further impacting yields. Especially in Xinjiang, where the "dry sowing and wet out" planting method is being promoted to conserve water and energy, seed drills often feature pointed bills that are narrow at the top and wide at the bottom. With thicker films, there's a greater chance that the pores won't be wide enough horizontally, or even unable to be punctured horizontally in some cases. The most important component that affects the horizontal width of the holes is the fixed duckbill of the seed drill. Therefore, it is necessary to design an improved fixed duckbill of the seed drill to improve the horizontal film breakage problem when the seed drill is punching during the sowing process. Summary of the Invention

[0003] In view of this, in order to solve the problem that the duckbill of the hole seeder cannot break the film horizontally when the film is relatively thick during sowing, an improved fixed duckbill of the hole seeder is needed, so that it can effectively break the horizontal position of the film during sowing, ensuring that there is enough space for seeds to emerge, thereby improving the survival rate of seeds.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0005] An improved duckbill seeding device comprises:

[0006] The fixed duckbill body is in a U-shape with a narrow top and a wide bottom, and its top is in an arc shape with a narrow top and a wide bottom. Two wings extend to both sides at a distance of 5 to 15 mm from the top of the fixed duckbill.

[0007] Preferably, the fixed duckbill body has cutting edges on its two wings that spread out to both sides, which is more conducive to cutting the ground film.

[0008] Preferably, the two wings of the fixed duckbill body that spread out to both sides are symmetrically arranged and are on the same plane as the arc-shaped plane of the top of the fixed duckbill.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The utility model provides an improved fixed duckbill seed drill. The arc on the top has a small area and a strong pressure, so it can effectively penetrate into a thicker film. The two wings that can be unfolded to both sides at any time can effectively cut the films on both sides, ensuring the lateral size of the holes to ensure that the seeds can germinate normally.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Example 1: According to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 The improved fixed duckbill of a seed drill shown in the figure includes a fixed duckbill body [1]. The fixed duckbill body [1] is generally U-shaped with a narrow top and a wide bottom. The top of the fixed duckbill body has a narrow top and a wide bottom arc

[11] . The arc

[11] can be a small semicircle or an ellipse. Its main purpose is to reduce the contact area, increase the pressure, and ensure that the top of the fixed duckbill body [1] can easily break into a thicker film. Below the arc

[11] , there are two wings

[12] that extend from the fixed duckbill body [1] to both sides at a distance of 5 to 15 mm from the top of the fixed duckbill. The two wings

[12] extend to both sides, increasing the lateral width of the fixed duckbill body [1], thereby effectively breaking the films on both sides and making the punching width meet the predetermined requirements, so that the seeds can grow smoothly from the holes after germination.

[0017] Preferably, the two wings

[12] are provided with cutting edges, which are more conducive to breaking the film.

[0018] Preferably, the side plane of the arc

[11] on the fixed duckbill body [1] is in the same plane as the side plane of the two wings

[12] . This is beneficial for the regular shape of the membrane hole after the fixed duckbill breaks the membrane, which is beneficial for seed germination.

[0019] The working process of the present invention is as follows: the fixed duckbill is fixed on the seed drill during use. During operation, when the seed drill is rolling, the circular arc

[11] of the fixed duckbill first contacts the ground film and breaks the ground film. Then, during the rolling process, the two wings

[12] cut into the ground film and completely break the ground film on both sides. Because the angles at the connection between the two wings

[12] and the circular arc

[11] vary greatly, the film can be forcibly broken, rather than the conventional fixed duckbill which squeezes the film with the cutting edges on both sides. Thus, the film on both sides of the fixed duckbill can be effectively cut, thereby improving the working effect.
