Translational seed metering type sowing and fertilizing machine

Abstract

The invention discloses a translational seed metering type sowing and fertilizing machine. Two sets of transmission devices are connected in parallel for use and can be simultaneously used for sowing and fertilizing or independently sowing or fertilizing. A steel cable 8 enables a seed metering device 23 to do reciprocal rectilinear motion on a guide rail 24; and required seeds or fertilizers are quantitatively separated out firstly and then fall into the ground along with a guide pipe 12 and a furrow opener 1 after translating by a certain distance. Thus, the technical problems of low seed metering speed, few functions, imprecision in quantification and unadjusted row spacing are solved. The translational seed metering type sowing and fertilizing machine is scientific in seed metering principle and transmission way and can be used for quantitatively sowing seeds of various crops such as peanuts, beans, corns, wheat, coarse cereals, cotton, sesame, rape, vegetables, flowers and rice, and various granular substances such as fertilizers at fixed positions.

Description

technical field [0001] The invention relates to an agricultural machine which can not only perform sowing and fertilization simultaneously, but also can sow seeds and fertilize separately. Specifically, the utility model relates to a translating seed row type seeding and fertilizing machine, which belongs to the technical field of agricultural machinery. Background technique [0002] What is used more in the world at present is the rotary seeding type seeder, and the seed metering device it uses is a cylinder, and the rotary motion of the ground wheel is changed into the rotary motion of the seed metering device by a gear-chain transmission device. There are following problems in this sorting method: [0003] 1. The seeding speed is slow. If the seed metering device turns fast, the seeds will be thrown out of the seed nest under the action of centrifugal force, causing the seed metering device to run idly, resulting in missed seeding and affecting crop yield. [0004] 2. I...

AI Technical Summary

Problems solved by technology

[0003] 1. If the seeding speed is slow, if the seed metering device turns fast, the seeds will be thrown out of the nest under the action of centrifugal force, causing the seed metering device to run idly, resulting in missed seeding and affecting crop yield

[0004] 2. It is inconvenient to adjust the distance between plants. The transmission ratio between the ground wheel and the gear is fixed, and the distance between plants is fixed. If you want to change the distance between plants, you must replace different gear widths;

[0005] 3. There are few functions, such as sesame, rapeseed, vegetables and other small grain crops, it has been powerless so far; even if it can achieve multiple functions, it is obviously unreasonable to use the same plant spacing for different crops

[0006] 4. Waste seeds, its circumference is almost one-third of the distance between corn plants, so two-thirds of the seeds should be wasted in vain

In addition, it takes time to thin the seedlings

[0007] In addition, the utility model patent - multifunctional quantitative positioning seeding and fertilizing machine, the patent number is: ZL 20072 0086516.8, has the phenomenon that the adjustment rod is not resistant to fatigue, and the seed meter is distorted and deformed, which is unfavorable for use
