A seed singulator for use with a vacuum disk having a seed face and a shoulder. The seed singulator has a first member and a second member supported by biasing members. The first member has upper lobes disposed at a radius of curvature slightly less than the outside radius of a row of apertures on a seed plane of the vacuum disk. The seed member has lower lobes disposed at a radius of curvature slightly greater than the inside radius than the row of apradius. The biasing members permit the lobes to move with the seed plane and the shoulder as the vacuum disk rotates thereby maintaining their position with respect to the apertures.

The invention provides an effective cleaning method of rubus lambertianus fruits. The cleaning method comprises the following steps of removing fruit stems and sepals of rubus lambertianus aggregate fruits; then putting the rubus lambertianus aggregate fruits without the fruit stems and the sepals on a stainless steel screen stencil of which the hole diameter is 0.71-1.4mm in a plastic box, and under the rinsing of running water, performing grinding with a rubber stopper so that fruit kernels are separated from fruit pulp to fall onto the surface of the screen stencil and the fruit pulp and most of fruit peel are washed away along with the water; spreading cleaned fruit kernels and a few fruit peel residues on a stainless steel filter net, performing drying in shade for 5-7 days, and then putting the dried fruit kernels and the dried fruit peel residues in a drying room for drying for a week; putting the dried fruit kernels and a few dried fruit peel residues into a seed separator, and under the wind power of a fan of which the rotating speed is 24.74-35.26Hz, enabling full fruit kernels to be separated from empty, shrivelled and worm-eaten fruit kernels and fruit peel residues; and finally packaging cleaned full fruit kernels with paper bags. The method is simple and effective, and under the situation that the fruit kernels are not damaged, the purity, the cleanliness and the full rate of the fruit kernels of the cleaned rubus lambertianus can reach 100%. In addition, the method is also suitable for cleaning other rubus fruits, other drupes and berries.

A differential-speed plot seeding device, including a seed storage mechanism, a seed metering mechanism, and a sorting mechanism. The seed storage mechanism includes a seed pouring funnel, a seed storage tube, a lifting lever and a lever base, which are used to put and store seeds, and the lifting lever It is used to drive the seed storage cylinder to lift upwards, and the seeds are filled; the seed metering mechanism includes a cone, a parallel inclined plate type seed transport grid, a differential transmission device and a stepping motor, and the stepping motor provides power, through the differential transmission The device realizes the differential rotation of the cone and the parallel inclined plate type seed grid, and the parallel inclined plate type seed grid is divided into multiple spaces by multiple parallel partitions; the sorting mechanism includes a seed collection funnel, a seed divider and a DC motor , the DC motor rotates at a high speed to evenly distribute the seeds falling from the seed opening into each row. The differential speed seeding method solves the problems of unevenness between rows and low precision; the use of parallel slanting plate seed transport grids to divide the space solves the problem of seed interruption caused by the presence of partitions in the seeding machinery.

The invention discloses an agricultural seeding device, which comprises a seed box and a base. The bottom of the base is symmetrically provided with a plurality of load-bearing columns, and the lower ends of the load-bearing columns are fixed with moving wheels. Above the base, there is a seed divider below the seed box, and a seed pipe at the bottom of the seed box. The lower end of the seed pipe is connected to the input end of the seed divider, and the output end of the seed divider is connected to a seed conduit. The end of the seed conduit away from the seed divider extends to the bottom of the base. The seed conduit slides on the pipe section below the base and the sealing sleeve is provided with a ground pipe. The base is fixed with an air pump, and the output end of the air pump is connected to the first air guide tube. The base is fixed with a water tank and a fertilizer tank. The device adopts a combination of push type and ground type sowing operation mode. After sowing, irrigation and fertilization operations can be completed synchronously. It saves time and effort, is easy to operate, and greatly improves the cultivation efficiency. practical.

The invention discloses a chilli hull and seed separator which comprises a feeding mechanism, a crushing mechanism, a distributing mechanism and a drive mechanism, wherein the crushing mechanism comprises a first support frame, a mixing and crushing wheel, a feeding hopper, a crushing bin, a discharging hopper and crushing gratings, the mixing and crushing wheel comprises a rotating shaft and a crushing member, the crushing gratings are laid along the arc shape of the bottom of the crushing bin at equal intervals; the distributing mechanism comprises a second support frame, a screen, a screen suspending rod and a guide dustpan; the drive mechanism comprises a drive motor, a first belt wheel, a second belt wheel and a crankshaft connecting rod system; the drive motor drives the mixing and crushing wheel by means of the first belt wheel to rotate, and a rotating shaft of the mixing and crushing wheel drives a crankshaft of the crankshaft connecting rod system by means of the second belt wheel to rotate so as to drive the screen to swing forwards and backwards swing and simultaneously vibrate slightly up and down. The chilli hull and seed separator is simple in structure, novel in design, skilled in design, and high in automation degree, and has two functions of crushing and separating; the production efficiency and the chilli seed quality are remarkably improved.

The invention discloses an air guide device, a sieve plate with an air guide device and a cleaning machine, relates to the field of agricultural machinery, and its main purpose is to solve the problem that the wind blown by the fan in the prior art cannot be evenly blown to the vibrating table surface Every corner leads to the problem that the seed stratification is not obvious and affects the cleaning quality of the seed. The main technical solution of the present invention is: the air guide device includes a body, a plurality of air guide grooves, and a plurality of air guide plates; a plurality of air guide grooves are arranged on the body; a plurality of air guide grooves include four parts The slots are the air guide slots at the feed inlet, the air guide slots at the discharge port, the light miscellaneous air guide slots and the heavy miscellaneous air guide slots; multiple air guide plates are arranged on the body, respectively located at the feed inlet air guide slots, In the light miscellaneous air duct and the heavy miscellaneous air duct; the air guide plate and the air duct form a certain angle according to the upwind direction. The invention is mainly used in the process of cleaning seeds by a seed cleaning machine.
