[0002] Before planting cereals, it is necessary to carry out seed dressing first, that is, to coat the required liquid medicine on the surface of the seeds to improve the germination rate of the seeds and prevent seed diseases and insect pests. In traditional techniques, manual seed dressing is adopted. First, the required medicine is mixed into water and stirred evenly to obtain the liquid medicine for seed dressing, and then the liquid medicine is poured into the seed dressing bucket containing the seeds. The breeding personnel use a stirring rod to stir the liquid medicine and the seeds. This seed dressing method is prone to uneven stirring, time-consuming and laborious, and has low efficiency. In the prior art, in order to solve the technical problem of time-consuming and laborious stirring in the traditional technique, a seed dressing machine is used for seed dressing. The seed dressing machine includes a seed dressing bucket, a seed dressing motor is fixedly connected to the outside of the seed dressing bucket, a stirring shaft is rotatably connected in the seed dressing bucket, and a plurality of stirring blades are arranged on the stirring shaft. The seed dressing motor is connected to the stirring shaft. An upper seed discharging port for facilitating discharging is opened at the lower end of the seed dressing bucket. There are various forms to realize the opening and closing of the upper seed discharging port, which will not be elaborated here. Before seed dressing, the seeds are first poured into the seed dressing bucket, and then an appropriate amount of liquid medicine is poured into the seed dressing bucket. After pouring is completed, seed dressing starts. If the seed dressing is completed, the seed dressing motor stops operating, and the situation of the liquid medicine coated on the seeds is checked. If the seed dressing requirement is met, the upper seed discharging port is opened, and the seeds fall into the recycling box below the seed dressing bucket through the upper seed discharging port. Otherwise, according to the seed dressing experience of the staff, an appropriate amount of liquid medicine is poured into the seed dressing bucket, the seed dressing motor is turned on, and seed dressing is carried out. After the seed dressing is completed, the seed dressing motor is turned off, the upper seed discharging port is opened, and the seeds fall into the recycling box below the seed dressing bucket through the upper seed discharging port, and then the above actions are repeatedly performed until the seed dressing operation of all seeds is completed. Although it improves the efficiency of stirring the seeds, before each seed dressing, it is necessary to prepare the weighed seeds and liquid medicine, which is troublesome to operate and still time-consuming and laborious.

Embodiment 1

[0033] Referring to Figure 1 、 Figure 7 and Figure 8 , which is the first embodiment of the present invention. This embodiment provides an automatic grain seed dressing device, including a seed dressing assembly 200, which includes a seed dressing box 201. At least one seed dressing shaft 203 is rotatably connected inside the seed dressing box 201. A seed dressing motor 226 is also fixedly connected outside the seed dressing box 201. The seed dressing motor 226 is connected to the seed dressing shaft 203. A number of seed dressing rods 202 are arranged on the outer circumference of the seed dressing shaft 203. The length of the seed dressing rods 202 is set according to actual needs. The length of the seed dressing rods 202 in the drawings does not represent the actual length used. The bottom of the seed dressing box 201 has an openable upper seed discharging port 201c. A material transmission assembly 300 is provided on the upper side of the seed dressing box 201.

[0034] During seed dressing, the seed dressing motor 226 operates, the seed dressing shaft 203 rotates, the seed dressing shaft 203 drives each seed dressing rod 202 to rotate, and the seed dressing rods 202 stir the seeds entering the seed dressing box 201 to achieve automatic stirring of the seeds.

[0035] Specifically, the material transmission assembly 300 includes a fixing plate 301 fixedly connected to the upper side of the seed dressing box 201. An upper feed port 301a is opened on the fixing plate 301. A liquid spraying pipe 306 is connected to the lower side of the fixing plate 301. An annular liquid spraying ring 307 is fixed inside the liquid spraying pipe 306. The inner ring of the liquid spraying ring 307 protrudes towards the center direction of the liquid spraying pipe 306. A number of atomizing spray holes 307a are arranged on the liquid spraying ring 307. The atomizing spray holes 307a are in the shape of Venturi nozzles. The inner ring of the liquid spraying ring 307 covers the upper feed port 301a. A closed liquid cavity X is formed between the outer side of the liquid spraying ring 307 and the inner side of the liquid spraying pipe 306. At least one high-pressure liquid pipe is connected to the liquid spraying pipe 306. The inner cavity of the high-pressure liquid pipe is communicated with the liquid cavity X. The end of the high-pressure liquid pipe away from the liquid spraying pipe 306 extends outside the fixing plate 301. A transmission sleeve 303 is fixedly connected to the upper side of the fixing plate 301. A transmission shaft 304 is rotatably connected inside the transmission sleeve 303. A spiral transmission blade 305 is provided on the transmission shaft 304. A feed hopper 302 is fixed on the upper side of one end of the transmission sleeve 303.

The transmission shaft 304 drives the spiral transmission blade 305 to rotate. Adjust the rotation direction of the transmission shaft 304 to convey the seeds in the direction where the upper feed port 301a is located. The seeds fall from top to bottom at the upper feed port 301a. At the same time, the liquid suction pump is turned on, and the medicament solution is pumped out by the liquid suction pump. The pumped-out medicament solution enters the liquid spraying pipe 306 and then enters the liquid cavity X. It is sprayed into the middle channel of the liquid spraying ring 307 through a number of atomizing spray holes 307a arranged on the concave curved surface of the outer circle of the liquid spraying ring 307 and is instantly atomized. The atomized medicament solution is sprayed onto the falling seeds, enabling the seeds to be coated with the medicament solution during the falling process. By only adjusting the pressure of the medicament solution input into the high-pressure liquid pipe and the rotation speed of the transmission shaft 304 according to the amount of seeds falling from the upper feed port 301a per unit time, the adjustment of the amount of medicament solution sprayed on the seeds can be achieved, which is more convenient to operate; the seeds falling into the seed dressing box 201 are further stirred by the seed dressing rod 202 to improve the uniformity of the medicament solution coated on the seeds.

A number of push-pull rods 222 are arranged on the outer periphery of the opening and closing rod 218. A rotating hook 222a is fixed to the end of the push-pull rod 222. A number of installation grooves 203a corresponding to the push-pull rods 222 one by one are formed on the outer periphery of the seed dressing shaft 203. A first installation sink is formed on the inner side of the first opening and closing sleeve 215 away from the second opening and closing sleeve 216. A second installation sink is formed on the inner side of the second opening and closing sleeve 216 away from the first opening and closing sleeve 215. A first support member 220 is rotatably connected in the first opening and closing sleeve 215 at the first installation sink. A second support member is rotatably connected in the second opening and closing sleeve 216 at the second installation sink. Annular rotating sinks are formed on the outer edge of the first opening and closing sleeve 215 at the outer edge of the first installation sink and on the outer edge of the second opening and closing sleeve 216 at the outer edge of the second installation sink. The structures of the first support member 220 and the second support member are the same. Taking the first support member 220 as an example for description, the first support member 220 includes a support ring 220c just sleeved on one seed dressing shaft 203. A number of support portions 220a are arranged on the outer edge of the support ring 220c. A rotating ring 220b having the same shape as the rotating sink is fixed to the outer edge of the support portion 220a. The rotating ring 220b can rotate in the rotating sink. The first baffle 221 and the second baffle 217 are respectively sleeved on the two seed dressing shafts 203 on the outer side in the axial direction of the two rotating sinks. The first baffle 221 is fixedly connected to the first opening and closing sleeve 215 to limit the axial movement of the corresponding rotating ring 220b. The second baffle 217 is fixedly connected to the second opening and closing sleeve 216 to limit the axial movement of the corresponding rotating ring 220b. The two rotating hooks 222a respectively hook the support ring 220c of the first support member 220 and the support ring 220c of the second support member.

[0043] During seed dressing, the side where the first opening and closing plate 223 and the second opening and closing plate 224 are oppositely arranged are closely attached together. The seed dressing shaft 203 drives the opening and closing driver 219 to rotate. The rotating hook 222a in one seed dressing shaft 203 drives the first support member 220 to rotate, and the rotating hook 222a in the other seed dressing shaft 203 will drive the second support member to rotate, rather than driving the first opening and closing sleeve 215 and the second opening and closing sleeve 216 to rotate, improving the separation between the opening and closing action and the seed dressing action. When the second support for seed dressing ends, the two opening and closing drivers 219 act, causing the two opening and closing rods 218 to move away from each other. The push-pull rod 222 in one seed dressing shaft 203 pulls the first support member 220 to move away from the second opening and closing sleeve 216 through the rotating hook 222a, and the push-pull rod 222 in the other seed dressing shaft 203 pulls the second support member to move away from the direction where the first opening and closing sleeve 215 is located through the rotating hook 222a. The first opening and closing plate 223 and the second opening and closing plate 224 move away from each other, and there is a gap between the first opening and closing plate 223 and the second opening and closing plate 224 for the seeds to fall, and the seeds are discharged downward.

[0044] Specifically, a first anti-blocking plate 215a-1 that fits on the upper side of the bottom of the seed dressing box 201 is fixed on the first vertical rod 215a above the first opening and closing plate 223, and a second anti-blocking plate 216a-1 that fits on the upper side of the bottom of the seed dressing box 201 is fixed on the first vertical rod 215a above the second opening and closing plate 224. The first anti-blocking plate 215a-1 and the second anti-blocking plate 216a-1 can slide along the upper side of the bottom of the seed dressing box 201. The inner walls of the seed dressing box 201 on both sides of the upper seed discharging port 201c facing outward both have a seed dressing discharging and sliding surface that slopes downward towards the upper seed discharging port 201c.

[0045] The seeds after seed dressing slide down along the seed dressing discharging and sliding surface and fall into the gap between the first baffle plate 221 and the second baffle plate 217. The settings of the first anti-blocking plate 215a-1 and the second anti-blocking plate 216a-1 prevent the seeds from falling on the upper sides of the first baffle plate 221 and the second baffle plate 217, and the first baffle plate 221 and the second baffle plate 217 can smoothly slide along the first sliding sink 201a and the second sliding sink 201b respectively.

The seeds pass through the discharge hole and the discharge opening and fall onto the discharge hopper 213, and the seeds discharged from the discharge hopper 213 wait for further dressing. If the dressing requirements are met, a collection bucket for collecting the dressed seeds is placed below the discharge frame 212, the lifting motor 211 operates, the lifting screw rod 225 rotates, and the lifting block 214 moves up and down. The operation direction of the lifting motor 211 is controlled to make the lifting block 214 move downwards, the opening and closing block 209 leaves the discharge base 204, and at the same time, the operation direction of the circulating material conveying motor 207 is adjusted to make the seeds convey towards the direction where the discharge opening 204a is located. The dressed seeds after the dressing ends fall through the discharge opening 204a. Part of the falling seeds slide down along the discharge seed sliding surface 210a and fall into the collection bucket, and the other part directly falls into the collection bucket, realizing the collection of the dressed seeds after the dressing ends.
