Description

Technical Field

[0001] The present invention relates to the technical field of fresh corn seed processing, and particularly to a seed dressing device for fresh corn seeds. Background Art

[0002] During the period from the sowing of fresh corn seeds to emergence, the seeds are often infected by pathogens and pests. To reduce the risks during emergence, seed coating treatment is generally carried out using a seed coating agent. In traditional techniques, the seed coating agent is poured into a stirring barrel, and then the fresh corn seeds are poured into the stirring barrel. An operator inserts a stirring rod into the stirring barrel by hand and holds the stirring rod to stir the fresh corn seeds and the seed coating agent. After stirring evenly, the dressed fresh corn seeds are poured out of the stirring barrel, and the above actions are repeated to complete the seed dressing operation for a number of fresh corn seeds. The seed dressing efficiency is low and the labor cost is high. In the prior art, an automatic seed dressing machine is used for coating fresh corn seeds. The automatic seed dressing machine includes a seed dressing barrel, and a stirring spiral auger is arranged inside the seed dressing barrel. The outer edge of the stirring spiral auger is closely attached to the inner side of the stirring barrel. A funnel for storing fresh corn seeds is fixed above the stirring barrel. The seed coating agent is pumped by an electric motor and sprayed into the stirring barrel. The fresh corn seeds falling from the funnel enter the stirring barrel, and the fresh corn seeds and the seed coating agent are stirred by the continuously rotating stirring spiral auger, so that the fresh corn seeds are coated with the seed coating agent. Although it can improve the seed dressing efficiency, after a number of seeds enter the stirring barrel, they come into contact with the seed coating agent concentratedly, and the fresh corn seeds cannot be evenly coated with the seed coating agent, and the seed dressing is not uniform enough. Summary of the Invention

[0003] In view of the problems existing in the existing fresh corn seed dressing devices as described above, the present invention is proposed.

[0004] Therefore, the problem to be solved by the present invention is that after a number of seeds enter the stirring barrel, they come into contact with the seed coating agent concentratedly, and the fresh corn seeds cannot be evenly coated with the seed coating agent. In the present invention, the atomized seed coating agent is sprayed out through the upper atomizing liquid spraying port, and the seeds are evenly dispersed and thrown out by the continuously rotating seed throwing sleeve. The atomized sprayed seed coating agent is evenly sprayed onto the fully dispersed seeds. At the same time, the seed throwing sleeve makes a reciprocating linear motion in the height direction, further improving the dispersion degree of the seeds, so as to further increase the direct contact area between each seed and the seed coating agent and further improve the pre-seed dressing effect.

[0026] Embodiment 1 Refer to Figures 1 - 5, which is the first embodiment of the present invention. This embodiment provides a fresh corn seed dressing device, including a seed metering assembly 100, which includes a fixing frame 103. Above the fixing frame 103, a seed metering box 101 is fixedly connected. Below the seed metering box 101, a seed metering device 109 fixedly connected to the upper side of the fixing frame 103 is provided; a pre-dressing assembly 200 for pre-dressing seeds is connected to the fixing frame 103.

[0027] Specifically, the pre-dressing assembly 200 includes a fixed housing 216. At the top of the fixed housing 216, a cover plate 213 is fixed. The fixing frame 103 is fixedly connected to the upper side of the cover plate 213. Below the cover plate 213, a pre-dressing housing 215 with a pre-dressing channel 2151 is fixedly connected. The pre-dressing channel 2151 runs through the axial direction of the pre-dressing housing 215. At the top of the fixing frame 103, a fixing plate is fixed. A seed dropping hole is opened on the fixing plate. Below the fixing plate, an intermediate seed sleeve 201 covering the seed dropping hole is fixedly connected. A seed metering pipe 203 capable of making a reciprocating linear motion in the height direction is connected to the intermediate seed sleeve 201. At the lower part of the fixing frame 103, a rotating sleeve 221 capable of moving up and down with the seed metering pipe 203 is rotatably connected. When the rotating sleeve is at the lowest position, the upper side of the rotating sleeve is not lower than the height where the lower side of the cover plate 213 is located. At the lower side of the rotating sleeve 221, a seed throwing sleeve 217 with an upward inoculation port 2171 is fixedly connected. At the top of the seed throwing sleeve 217, a conical seed sliding part 2172 is fixed. On the seed throwing sleeve 217 at the outer edge of the seed sliding part 2172, a number of seed metering channels 2173 inclined downward in the direction from the inner edge to the outer edge of the seed throwing sleeve 217 are arranged. In the upper part of the pre-dressing housing 215, a number of groups of atomizing liquid spraying units spaced apart in the height direction are arranged. Each group of atomizing liquid spraying units is composed of a number of upper atomizing liquid spraying ports 2141 arranged at the same height and spaced apart in the circumferential direction.

[0028] The lower side of the seed-throwing sleeve 217 is not lower than the bottom of the lowermost upper atomizing liquid spraying port 2141. The moving range of the seed-throwing sleeve 217 in the height direction is within the height range of several groups of atomizing liquid spraying units. The upper end of the fixed housing 216 is connected with a liquid inlet pipe 219, and the liquid inlet pipe 219 is connected with an external liquid pump. A seed dressing liquid ring 214 is fixed inside the upper part of the pre-seed dressing housing 215. The cross-sectional structure of the seed dressing liquid ring 214 is a curved surface recessed towards the radial center of the pre-seed dressing housing 215. The upper atomizing liquid spraying port 2141 is arranged on the seed dressing liquid ring 214. A closed liquid cavity is formed between the outer edge of the seed dressing liquid ring 214 and the inner side of the pre-seed dressing housing 215. The end of the liquid inlet pipe 219 far from the liquid pump is connected with the pre-seed dressing housing 215 and communicates with the liquid cavity. During operation, the seed coating agent is pumped out by the liquid pump, and the pumped-out seed coating agent is sprayed into the liquid cavity. The seed coating agent is atomized through several upper atomizing liquid spraying ports 2141 and sprayed towards the direction of the seed-throwing sleeve 217. The seed discharger 109 operates, and the fresh corn seeds in the seed box fall controllably through the seed discharger 109. The seeds discharged from the seed discharger 109 fall into the seed discharging pipe 203 through the intermediate seed sleeve 201. The seeds discharged from the seed discharging pipe 203 fall into the inoculation port 2171. The seeds slide downward along the seed sliding part 2172 and slide out downward from the seed sliding part 2172. The seeds sliding downward from the seed sliding part 2172 are discharged outward through the seed discharging channel 2173. The seed-throwing sleeve 217 rotates continuously, and the seeds sliding down through the seed discharging channel 2173 are thrown out. The fresh corn seeds are evenly dispersed under the action of several evenly arranged seed discharging channels 2173. At the same time, the seed discharging pipe 203 makes a reciprocating linear motion in the height direction, and the seed discharging pipe 203 drives the seed-throwing sleeve 217 to make a reciprocating linear motion in the height direction, further improving the dispersion degree of the fresh corn seeds, further increasing the direct contact area between each seed and the seed coating agent, further improving the pre-seed dressing effect, and improving the uniformity of the seed coating agent wrapped on each fresh corn seed.

[0029] Embodiment 2 Refer to Figures 2 - 5 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0030] Specifically, a limiting platform 2212 is fixedly connected inside the rotating sleeve 221. A through hole for the seed tube to pass through is formed in the center of the limiting platform 2212. A circular rotating counterbore is formed at the lower end of the limiting platform 2212 facing downwards. A limiting sleeve 218 is fixedly connected to the lower end of the seed discharging tube 203. A connecting hole is formed in the limiting sleeve 218. The seed discharging tube 203 is made of a hard material, such as a light metal like aluminum alloy. A connecting counterbore is formed at the lower end of the seed discharging tube 203 facing downwards. The upper side of the limiting sleeve 218 contacts the limiting platform 2212 on the upper side of the rotating counterbore. The limiting platform 2212 is rotationally connected to the limiting sleeve 218 through the rotating counterbore. The upper end of the seed throwing sleeve 217 can contact the lower side of the limiting sleeve 218. A circular inserting counterbore is formed at the upper end of the seed throwing sleeve 217. A plurality of fixing holes are arranged on the seed throwing sleeve 217 on the outer edge of the inserting counterbore. A plurality of fixing counterbores corresponding to the fixing holes one by one are arranged on the rotating sleeve 221. When the upper sliding hole 2211 and the lower sliding hole 2174 are aligned, the fixing holes and the corresponding fixing counterbores are coaxial.

[0031] A seed dropping hole communicating with the inner cavity of the seed discharging tube 203 is formed in the center of the limiting sleeve 218. When the seed discharging tube 203 moves upwards, the seed discharging tube 203 drives the rotating sleeve 221 to move upwards through the limiting sleeve 218, and the rotating sleeve 221 drives the seed throwing sleeve 217 to move upwards. When the seed discharging tube 203 moves downwards, the seed discharging tube 203 drives the seed throwing sleeve 217 to move downwards through the limiting sleeve 218, and the seed throwing sleeve 217 drives the rotating sleeve 221 to move downwards. Through the above structure, the function of the seed throwing sleeve 217 rising and falling synchronously with the seed discharging tube 203 is realized, and at the same time, the rotation action of the seed throwing sleeve 217 is not affected, and its structure is simple and ingenious.

[0032] Before installing the seed throwing sleeve 217, first install the limiting sleeve 218 on the lower side of the seed discharging tube 203. Specifically, the lower part of the seed discharging tube 203 passes through the through hole, insert the limiting sleeve 218 into the rotating counterbore, and use fastening bolts to screw into the connecting hole and the connecting counterbore to fixedly connect the limiting sleeve 218 to the lower side of the seed discharging tube 203. The seed throwing sleeve 217 is just inserted into the rotating sleeve 221 through the inserting counterbore. Rotate the seed throwing sleeve 217 to align the lower sliding holes 2174 with the upper sliding holes 2211 one by one. The transmission rod 220 passes through the lower sliding holes 2174 to realize the installation positioning of the seed throwing sleeve 217 in the circumferential direction. Continue to move the seed throwing sleeve 217 upwards. When the lower side of the seed throwing sleeve 217 below the inserting counterbore contacts the lower side of the rotating sleeve 221, the seed throwing sleeve 217 still contacts the lower side of the limiting sleeve 218. Use a plurality of fastening bolts and other fasteners to screw into the fixing holes and the corresponding fixing counterbores one by one to fixedly connect the seed throwing sleeve 217 to the rotating sleeve 221. When screwing in the fasteners, due to the setting of the transmission rod 220, the seed throwing sleeve 217 will not rotate and shift, and the installation is convenient and reliable.

[0033] Specifically, a transmission sleeve 206 rotatably connected to the seed metering tube 203 is rotatably connected to the fixing frame 103. A number of transmission rods 220 are arranged on the transmission sleeve 206. A number of upper sliding holes 2211 and lower sliding holes 2174 corresponding to the transmission rods 220 one by one are respectively arranged on the limiting platform 2212 and the seed throwing sleeve 217. The rotating sleeve 221 and the seed throwing sleeve 217 are respectively slidably connected to the transmission rods 220 through the upper sliding holes 2211 and the lower sliding holes 2174.

[0034] When the transmission sleeve 206 rotates, the transmission sleeve 206 drives the seed throwing sleeve 217 to rotate through the transmission rod 220. At the same time, when the seed throwing sleeve 217 moves up and down, the seed throwing sleeve 217 slides up and down along the transmission rod 220, which will not affect the rotation of the transmission sleeve 206. Its structure is compact and ingenious.

[0035] In order to further realize the rotation of the seed throwing sleeve 217, a seed metering shaft 102 is rotatably connected above the fixing frame 103. The seed metering shaft 102 is connected to the seed metering device 109 (the seed metering device 109 is a prior art, and its structure is schematic, which does not affect the understanding of its solution by those skilled in the art. When the seed metering shaft 102 rotates, the seed metering groove wheel of the seed metering device 109 rotates to realize seed metering). The seed metering shaft 102 is in transmission connection with the transmission sleeve 206. The specific structure is that a driven wheel 104 is connected to the seed metering shaft 102. A driving shaft 108 is rotatably connected to the fixing frame 103 below the seed metering shaft 102. A support plate 209 is fixedly connected to the fixing frame 103. A connecting shaft 208 is fixedly connected to the driving shaft 108. The connecting shaft 208 is rotatably connected to the support plate 209. A driving wheel 107 is connected to the driving shaft 108. A driving bevel gear 210 is connected to the connecting shaft 208. The driving wheel 107 is connected to the driven wheel 104 through a transmission belt 105. The upper end of the transmission sleeve 206 is connected with a transmission bevel gear 205 that cooperates with the driving bevel gear 210. A transmission motor 106 is fixedly connected to the outside of the fixing frame 103. The transmission motor 106 is connected to the driving shaft 108.

[0036] During operation, the transmission motor 106 operates, the driving shaft 108 rotates, the driving shaft 108 drives the driving wheel 107 and the driving bevel gear 210 to rotate. The driving wheel 107 drives the driven wheel 104 to rotate through the transmission belt 105. The driven wheel 104 drives the seed metering shaft 102 to rotate. The seed metering shaft 102 drives the seed metering device 109 to operate, and the seed metering device 109 meters seeds. The driving bevel gear 210 drives the transmission bevel gear 205 to rotate. The transmission bevel gear 205 drives the transmission sleeve 206 to rotate. The transmission sleeve 206 drives the rotating sleeve 221 to rotate through the transmission rod 220. The rotating sleeve 221 drives the seed throwing sleeve 217 to rotate, realizing the automatic seed metering of fresh corn seeds in the seed box and the uniform dispersion of fresh corn seeds.

[0037] Embodiment 3 Refer to Figures 4 - 6, which is the third embodiment of the present invention. This embodiment is based on the previous two embodiments and can further realize the synchronous movement of the seed-throwing sleeve 217 and the seed metering tube 203, further improving the uniformity of the fresh corn seeds coated with the seed dressing agent.

The second moving plate 211 abuts against the upper side of the moving sleeve 212. The second moving plate 211 is fixedly connected to the upper side of the first moving plate 204.

[0039] When the first moving plate 204 moves up and down, the first moving plate 204 drives the second moving plate 211 to move up and down. The first moving plate 204 and the second moving plate 211 drive the seed metering tube 203 to move up and down through the moving sleeve 212.
