Friction wheel type material acceleration device with self-adaptive distance adjustment function

Abstract

The invention relates to the technical field of crop planting instruments, in particular to a friction wheel type material acceleration device with a self-adaptive distance adjustment function. The device comprises the components of a mounting plate; an accelerating tube which is mounted on the mounting plate, and through holes are formed in the left and right sides of the accelerating tube; friction wheels which are installed on the two sides of the accelerating tube, and at least one part of each friction wheel is embedded into the corresponding through hole, so that the friction wheels rotate in the accelerating tube; a driving mechanism, wherein the power output end of the driving mechanism is connected with the friction wheel, and the driving mechanism is used for driving the friction wheel to rotate; and a self-adaptive adjusting assembly which is arranged on the mounting plate and used for adjusting the distance between the two friction wheels. According to different sizes of materials, the gap between the friction wheels is automatically adjusted, the materials are accelerated, and the seeding efficiency and the seeding accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of crop planting machinery, more specifically, to a friction wheel type material acceleration device with self-adaptive adjustment of spacing. Background technique [0002] Compared with ground machinery, the use of drones for aerial operations has better passability, and is more and more widely used in agricultural production. During the sowing operation of rice production, especially in cold soaked fields and deep muddy fields, ground machinery is very easy to get stuck in the car, and drone sowing has become a new sowing method. The rice sowing method of the drone in the prior art is mainly based on sowing, and the whereabouts of the rice seeds mainly depends on the weight of the rice seeds themselves. Due to the small weight of the seeds, they are easily affected by the natural wind and the rotor wind field of the drone during the falling process, resulting in an uncertain landing point. When the natura...

Publication No. is the patent of CN21904900U, has announced a kind of launch angle and friction wheel center distance adjustable ball machine mechanism device, can be used for launching small-sized balls such as table tennis, tennis ball, and its friction wheel gap can be adjusted, to adapt to the Balls of different sizes are launched, but the adjustment of the friction wheel gap needs to be manually adjusted before the friction wheel works, and it cannot be adjusted in real time with the different sizes of the launched objects.

[0004] The gap of the friction wheel in the existing friction wheel acceleration device is manually adjusted before the acceleration device works. The gap of the friction wheel is fixed and cannot be adjusted during the working process, which cannot meet the requirements of real-time self-adaptive adjustment of the distance, so the friction wheel acceleration device only It can launch spherical objects with a fixed size, and it cannot be adjusted adaptively according to the size of the launched objects. For materials such as coated rice seeds, the size and shape of each coated seed must be the same very difficult
