Problems solved by technology

However, the traditional hole sowing seed meter has a certain speed after the seeds leave the seed meter, and the collision with the wall of the seed delivery pipe will easily cause the seeds to splash around and fail to fall accurately into the seed hole. Poor cavitation effect
[0003] In addition, the existing seed metering device can only sow seeds with a certain particle size. In the case of poor sowing accuracy, it is easy to cause missed seeding and holes. Seeds are wasted, so it is necessary to urgently need a seed meter with adjustable nest size

Embodiment 1

[0042] This embodiment relates to a seed metering wheel assembly capable of adjusting the amount of seeding, which is pivotally arranged in the housing of the seed metering device. Its main structure includes a seed metering wheel, an adjusting shaft, an elastic pusher and an adjusting nut. It is constructed with a cavity that can accommodate seeds, and the size of the cavity can be changed by screwing in or out of the adjusting nut on the adjusting shaft, thereby realizing the adjustment of the sowing amount.

[0043] Based on the above structural design idea, an exemplary structure of this embodiment is as figure 1 As shown, the metering wheel includes a first wheel body 5 and a second wheel body 6 that are coaxially arranged, and the outer peripheral surface of the first wheel body 5 is configured to be arranged in the circumferential direction of the first wheel body 5 and alternately A plurality of cavities with different lengths are distributed at intervals. Each cavity exte...

Embodiment 2

[0051] This embodiment relates to a seed metering device, an exemplary structure such as 6 to Figure 8 As shown, the seed metering device includes a seed metering device housing 2 in which the seed metering wheel assembly capable of adjusting the sowing amount as described in the first embodiment is housed in the seed metering device housing 2 A seed cleaning brush 8 rotating in the same direction as the seed metering wheel is provided, and the bristles of the seed cleaning brush 8 are closely attached to the outer peripheral surface of the seed metering wheel.

[0052] Corresponding to the two rows of cavities 10 on the seed metering wheel described in the first embodiment, a partition plate is constructed on the seed meter housing 2 to form different metering grooves. Of course, it can also be passed on the partition plate A baffle is added to prevent the seeds in the seed box from falling into the seeding trough, so that a single row of cavities 10 can be planted, so that the ...

Abstract

The invention provides a seed sowing wheel component capable of adjusting sowing rate and a seed sowing device. The seed sowing wheel component capable of adjusting the sowing rate comprises a seed sowing wheel, an adjusting shaft, an adjusting nut and an elastic ejector part, the adjusting nut is connected on the adjusting shaft in a threaded manner, the elastic ejector part is arranged on the adjusting shaft in a sleeving manner and elastically abutted to a first wheel and a second wheel, the seed sowing wheel includes the first wheel and the second wheel which are coaxial, a plurality of cavities are alternately formed in the peripheral surface of the first wheel along a peripheral direction of the first wheel at intervals, the lengths of the cavities are different, each cavity extendsalong an axis direction of the first wheel, a plurality of projecting columns are alternately and correspondingly distributed on the peripheral surface of the second wheel at intervals, the lengths ofthe projecting columns are different, the projecting columns are placed into the corresponding cavity to form holes for containing seeds, and the sizes of the holes can be adjusted as the adjusting nut is screwed in or screwed out. According to the seed sowing wheel component capable of adjusting the sowing rate, the sowing rate can be adjusted, and the component has good practicability.

Description

Technical field [0001] The present invention relates to the technical field of agricultural machinery, in particular to a seed metering wheel assembly capable of adjusting the sowing amount. In addition, the present invention also relates to a seed metering device with the seed metering wheel assembly capable of adjusting the sowing amount. Background technique [0002] Peanuts are one of the important economic crops in my country. The planting area is relatively large. With the adjustment of the planting structure and the promotion of new technologies, the mechanization of peanut planting is also increasing. However, the traditional peanut hole planting and metering device has a certain speed after the seeds are separated from the seed metering device. The collision with the seeding tube wall can easily cause the seeds to splash around and fail to accurately fall into the seeding hole, resulting in uneven plant spacing and multiple seeds in one hole. Poor cavitation effect. [00...
