Description

Technical Field

[0001] The utility model relates to the technical field of seed coating machines, in particular to a screening device for a feed outlet of a seed coating machine. Background Art

[0002] A seed coating machine is a machine that coats the surface of carefully selected seeds with a coating agent to pelletize them, which is beneficial for sowing. A screening device is usually added to the discharge port of the seed coating machine to screen the coated seeds and remove seeds with uneven coating, which is beneficial for improving the growth rate of seeds and facilitating breeding and planting.

[0003] For example, in the Chinese patent with the announcement number CN218603920U, a seed coating machine is disclosed. The evenly coated seeds pass through the sieve holes of the sieve plate and are collected from the discharge port along the chute plate. The unqualified seeds stay at the upper end of the sieve plate. The box door is opened by rotating it around the hinge through the handle to collect and process the unqualified seeds on the surface of the sieve plate. The device can filter and collect the unevenly coated seeds and is easy to use. However, after the above-mentioned seed coating machine screens the seeds through the sieve plate, due to the lack of cleaning of the screening box, there will often be residual coating agents inside the screening box and on the sieve plate. After the coating agents are dried, it is easy to cause scaling inside the screening box and on the sieve plate, which will increase the probability of clogging of the sieve plate, which is not conducive to the screening of the coated seeds.

[0027] The top cover 4 is also provided with a spray mechanism 5 for spraying and flushing the screening mechanism 6, and the spray mechanism 5 includes a liquid inlet pipe 51 connected to the top of the top cover 4, and a spray pipe 52 arranged inside the top cover 4. A plurality of nozzles 53 are installed at the bottom end of the spray pipe 52, and the plurality of nozzles 53 are arranged in sequence from the middle to both sides. One end of the liquid inlet pipe 51 extends into the top cover 4, and a hose 54 is connected between the liquid inlet pipe 51 and the spray pipe 52.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, the screening mechanism 6 includes a screening plate 61 arranged inside the screening box 1, four fixed blocks 62 installed on both sides of the inner wall of the screening box 1, and a power part that drives the screening plate 61 to vibrate, the tops of the four fixed blocks 62 are connected to springs 63, and the tops of the four springs 63 are commonly connected to the bottom of the screening plate 61; the power part includes a first motor 65 fixed on the outer wall of the screening box 1, and a shaft rod 66 rotatably installed in the screening box 1, a cam 64 is installed in the middle of the shaft rod 66, and the convex end of the cam 64 can contact the bottom of the screening plate 61, and the first motor 65 is used to drive the shaft rod 66 to rotate.

[0029] When in use, the device can be installed below the discharge port of the seed coating machine, and the discharge port of the seed coating machine can be connected to the feed pipe on the top cover 4. When the seeds are coated by the coating machine and discharged through the discharge port of the seed coating machine, the seeds will be discharged into the screening cavity in the screening box 1 through the feed pipe. At this time, the first motor 65 drives the shaft 66 to rotate, so that the shaft 66 drives the cam 64 to rotate, and then the convex end of the cam 64 continuously touches the bottom of the screening plate 61, so that the screening plate 61 shakes under the action of the spring 63 to screen the coated seeds. At this time, the evenly coated seeds fall through the screening plate 61 and are discharged from the second discharge hopper 3, while the unqualified seeds remain on the screening plate 61 and are then discharged from the first discharge hopper 2, thereby realizing the screening of the coated seeds, which is beneficial to the subsequent breeding and planting;

[0030] After the screening is completed, the liquid inlet pipe 51 can be connected to the external water supply equipment, and the cleaning liquid can be input through the liquid inlet pipe 51 through the external water supply equipment, and then the cleaning liquid can be input into the spray pipe 52 through the hose 54, and then the cleaning liquid can be sprayed out through the nozzle 53 at the bottom of the spray pipe 52 to spray and rinse the screening cavity and the screening plate 61 inside it to remove the coating agent remaining in the screening cavity, thereby cleaning the screening cavity and the screening plate 61 inside it to prevent the screening plate 61 from scaling and clogging, which is beneficial to the subsequent use of the screening device.

[0031] Furthermore, if Figure 2 and Figure 3 As shown, the screening plate 61 is arranged at an angle, and the lower end of the screening plate 61 corresponds to the first discharge hopper 2 .

[0032] During the screening process of the coated seeds, the inclined screening plate 61 can guide the unevenly coated seeds remaining thereon into the first discharge hopper 2 and discharge them, thereby facilitating the rapid discharge of the unevenly coated seeds.

[0033] Furthermore, if Figure 2 and Figure 3 As shown, an inclined material guide plate 8 is further installed at the inner bottom of the screening box 1 , and the lower end of the material guide plate 8 corresponds to the second discharge hopper 3 .

[0034] When the evenly coated seeds fall through the screening plate 61, the guide plate 8 can guide the seeds so that the seeds quickly flow into the second discharge hopper 3 and are discharged, which is conducive to the rapid discharge of evenly coated seeds and realizes rapid discharge of the screening device.

[0035] In addition, in one embodiment, Figures 1-6 As shown, the top cover 4 is also provided with an adjusting mechanism 7 for driving the spray pipe 52 to move horizontally back and forth, and the adjusting mechanism 7 includes a concave cavity opened on one side of the inner wall of the top cover 4, and a screw rod 72 rotatably installed in the concave cavity, and a screw rod seat 75 that can slide along the concave cavity is sleeved on the screw rod 72, and one side of the screw rod seat 75 is fixedly connected to the spray pipe 52, and a second motor 71 is fixed to one side of the top cover 4, and the second motor 71 is used to drive the screw rod 72 to rotate.

[0036] When the spray pipe 52 sprays and flushes the screen plate 61, the second motor 71 can be used to drive the screw rod 72 to rotate, so that the screw rod 72 drives the screw rod seat 75 to move along it, and then the screw rod seat 75 drives the spray pipe 52 to move along the inside of the top cover 4 to achieve uniform spraying of the screen plate 61, thereby improving the flushing effect of the screen plate 61, which is beneficial to the subsequent use of the screening device.

[0037] Furthermore, in this embodiment, in order to ensure the stable movement of the spray pipe 52, as shown in FIG. Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, the adjustment mechanism 7 also includes a limiting groove opened on the other side of the inner wall of the top cover 4, in which a polished rod 73 is fixed. A slider 74 is installed on the side of the spray pipe 52 relative to the screw seat 75, and the slider 74 is slidably sleeved on the polished rod 73.

[0038] When the screw rod 72 drives the spray pipe 52 to move through the screw rod seat 75, the slider 74 slides along the light rod 73 to limit the position between the spray pipe 52 and the top cover 4, thereby ensuring the stable movement of the spray pipe 52, which is beneficial to the spraying and flushing of the screen plate 61.

[0039] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
