Embodiment 1

[0046] Embodiment 1: A sowing machine for fine single-grain sowing of wheat, suitable for the sowing process of wheat ontogeny experiments. The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0047] The seeder can be used as figure 1 As shown in the structure, it can be seen from the figure that the front side of the bracket extends forward and is provided with a front bushing, and a pair of ground wheels are installed, and the rear end of the bracket extends downwards, and a rear bushing is provided, and a pair of ground wheels are installed. follower wheel. A handle is installed on the upper part of the rear end of the support, and the seeder can be pushed to move forward after the handle is pushed. There are ground teeth on the periphery of the ground wheel. When the ground wheel walks along the trench (ditching in advance), the seeder is driven to work by the power output from the ground wheel and the tra...

Embodiment 2

[0064] Embodiment 2: On the basis of the implementation of Embodiment 1, an additional transmission can also be added to any output shaft of the gearbox, such as output shaft 1 or output shaft 2, or the gearbox or the corresponding transmission can be set to an adjustable speed ratio Speed ​​change mechanism, this kind of speed change mechanism is often operated by humans to achieve output speed change adjustment. When the frustum turntable 17 is designed with wear-resistant transparent materials (or the observation window is partially installed on the frustum turntable 17 and a transparent wear-resistant layer is installed), the rotation of the frustum turntable 18 inside the frustum turntable 18 and the surplus quantity of material distribution can be observed through perspective , in order to manually adjust the speed ratio of each speed change mechanism.

Embodiment 3

[0065] Embodiment 3: On the basis of Embodiment 2, the gearbox or the extra transmission is changed into an automatic transmission mechanism, and is controlled by the controller, and a sensor for detecting the excess amount of the distribution is set in the area of ​​the distribution mechanism of the conical frustum body, For example, a laser sensor probe or a contact sensor element is added to a certain section of the cone shell to continuously monitor the quantity of wheat grains lying on the sides in each passing trough. Sensors for detecting the accumulation of wheat grains can also be set in the distributor area, for example, a laser sensor probe or a contact sensing element is added in the inclined channel 46 to continuously monitor the number of lying wheat grains in each passing trough. .

[0066] The controller performs automatic speed change control on the corresponding speed change mechanism according to the corresponding detection data, or reminds people to perform...

Abstract

The invention discloses a wheat fine single-grain seeder suitable for individual development experiments. The wheat fine single-grain seeder comprises land wheels, a bracket, a handrail, a seeder, a transmission mechanism and the like. A seeding unit of the seeder comprises a frustum shell, a frustum turntable and a kick-out device, the frustum turntable is mounted in the frustum shell and can rotate, the frustum turntable selects out wheat grains in a horizontal state from wheat grains in a mixed state in a feed port of the frustum shell, stores the selected wheat grains in a material distribution groove, and transfers the selected wheat grains into the kick-out device; the wheat grains in the horizontal state are shifted and transferred to a seeding pipe one by one by a distributor. According to the wheat fine single-grain seeder suitable for the individual development experiments, only horizontal wheat grains in a large number of disorderly stacked wheat grains can be selected out, so that an inclined channel and an arc-shaped conveying channel are utilized to constrain the wheat grains, the horizontal wheat grains are stirred one by one by utilizing the kick-out device, and equal-interval single-grain seeding is realized. The single-seed sowing precision can be effectively ensured, and the phenomenon of repeated sowing of multiple seeds or the situation of miss-sowing can be avoided.

Description

technical field [0001] The invention belongs to the technical field of wheat sowing machinery, and in particular relates to a wheat fine single-grain sowing machine suitable for individual growth experiments. Background technique [0002] With the gradual and widespread application of agricultural machinery, the form, style and function of wheat sowing machinery have been continuously improved and increased, such as a seeder with an even row of seeds as an improved direction, a seeder with integrated functions of sowing and fertilization, and a seeder with the function of avoiding tillage. Machines, etc., but relatively lack of mechanical equipment for single-seed sowing of wheat. The structure of the traditional wheat seeder mainly includes the front fertilizing columbine legs fixed on the front beam of the frame, the rear sowing columbine legs fixed on the rear beam of the frame, and the compacting wheel. This type of wheat seeding equipment is mainly used for field sowing...
