Description

Technical Field

[0001] The utility model belongs to the technical field of wheat shelling machines, in particular to a seed shelling machine for wheat breeding. Background Art

[0002] The wheat sheller is used to peel off the shell of wheat seeds. The principle of the commonly used wheat sheller is to separate the wheat shell from the seeds by rolling the rollers in the sheller, and then use the fan to select the shell. Taking advantage of the light weight of the shell, the shell is blown to the air outlet of the sheller. The seeds are heavy and fall out of the seed outlet. The screen at the air outlet of the wheat sheller intercepts the shell and then falls out of the shell outlet, and the airflow is discharged from the air outlet. In the prior art, the wheat sheller has the following problems when in use: the shell is easily stuck in the mesh of the screen at the air outlet under the blowing of the fan, resulting in poor air outlet; the sheller is generally equipped with wheels for easy movement, but the wheels cannot be well fixed when the sheller is working, which makes the stability of the sheller poor when working. Even if a wheel with brakes is used, the brake mechanism of the wheel will be frequently damaged due to the high vibration frequency of the sheller. Summary of the invention

[0003] The utility model aims to provide a seed shelling machine for wheat breeding to solve the problems existing in the prior art.

[0004] The utility model solves the technical problem by adopting the following technical scheme: a seed shelling machine for wheat breeding comprises a frame, a shelling machine body is mounted on the frame, an air outlet is arranged at one end of the shelling machine body, the air outlet part of the shelling machine body is connected with a filter box, a bearing in the filter box is connected with a rotating shaft, a motor is fixedly connected with the top of the rotating shaft, a wind shield is welded on the rotating shaft, a shelling bucket is connected with the bottom of the filter box, a screen is inserted at one side of the filter box, a partition is welded inside the filter box, an arc plate is welded on the outside of the filter box, a plurality of rotating rods are hinged at the bottom of the frame, wheels are mounted at the bottom of the rotating rods, a support rod is welded on the rotating rod, and the middle part of the rotating rod is fixed to the frame by a bolt pair.

[0005] Furthermore, one end of the filter box is square, and the other end of the filter box is closed. The closed end of the filter box is connected to the air outlet. The shell outlet is located at the bottom of the square end of the filter box. The filter box is open on the side opposite to the air outlet. The partition is located in the middle position inside the square end of the filter box, and the partition divides the square end of the filter box into two parts.

[0006] Furthermore, two slots are welded symmetrically on the outer side of the open end of the filter box, and connecting rods are welded on the outer sides of the slots, and the arc-shaped plates are welded to the two connecting rods.

[0007] Furthermore, there are two screens, both of which are inserted between the two slots. The two screens correspond to the two parts of the filter box divided by the partition, and the screens are inserted into the filter box through the slots.

[0008] Furthermore, the rotating shaft is located at one end of the partition, and the wind shield divides the closed end of the filter box into two parts. The free end of the wind shield is close to the inner wall of the filter box, so that one side of the wind shield is connected to the air outlet and the other side is separated from the air outlet.

[0009] Furthermore, the upper and lower ends of the rotating rod are U-shaped, the bottom end of the frame is located in the U-shaped part of the upper end of the rotating rod, the hinge between the frame and the rotating rod is located in the U-shaped part of the upper end of the rotating rod, and the wheels are located in the U-shaped part of the lower end of the rotating rod.

[0010] Furthermore, the support rod is vertically welded to the upper end of the rotating rod, and one end of the support rod connected to the rotating rod is U-shaped, and the inner cavity of the U-shaped part of the support rod is connected to the inner cavity of the U-shaped part of the upper end of the rotating rod.

[0011] Furthermore, through holes are provided on the bottom end of the frame, the rotating rod and the support rod. The position of the through holes on the frame is located below the hinge between the frame and the rotating rod. The positions of the through holes on the rotating rod and the support rod correspond to the positions of the through holes on the frame. The bolt pair is inserted into the through holes of the frame and the rotating rod to fix the rotating rod to the frame.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model can switch the air outlet channel to make the shell easier to fall, and at the same time back-blow the screen to blow down the stuck shell. At the same time, it can also switch the support structure of the frame, which is convenient for movement and improves the stability in the working state.

[0014] 2. The filter box is divided into two air outlet channels by a wind shield and a partition, one of which is connected to the air outlet and the other is blocked by the wind shield. The wind shield is driven by a motor to rotate back and forth to achieve timed back and forth switching of the two air outlet channels. The shell on the screen of the air outlet channel blocked from the air outlet is easier to fall down due to the absence of the fan, thereby preventing the shell from accumulating on the screen.

[0015] 3. A part of the air flow blown out from the air outlet channel connected to the air outlet is blown toward the screen with the shell stuck on it under the guidance of the arc plate, thereby backblowing the screen, so that a small amount of shell stuck on the screen is backblown into the shell outlet bucket.

[0016] 4. By hingedly connecting the rotating rod to the bottom end of the frame, the wheels and the support rods can be switched back and forth, which not only facilitates movement but also improves stability in working state. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The utility model will now be further described in detail with reference to the accompanying drawings.

[0023] like Figure 1-4 As shown, a seed shelling machine for wheat breeding comprises a frame 1, a shelling machine body 2 is mounted on the frame 1, an air outlet 3 is arranged at one end of the shelling machine body 2, a filter box 4 is connected to the air outlet 3 of the shelling machine body 2, a rotating shaft 5 is connected to a bearing in the filter box 4, a motor 6 is fixedly connected to the top of the rotating shaft 5, a wind shield 6 is welded to the rotating shaft 5, a shelling bucket 8 is connected to the bottom of the filter box 4, a screen 9 is inserted at one side of the filter box 4, a partition 10 is welded inside the filter box 4, an arc plate 11 is welded to the outside of the filter box 4, a plurality of rotating rods 12 are hinged at the bottom of the frame 1, wheels 13 are arranged at the bottom of the rotating rods 12, a support rod 14 is welded to the rotating rod 12, and the middle part of the rotating rod 12 is fixed to the frame 1 by a bolt pair 15.

[0024] One end of the filter box 4 is square, and the other end of the filter box 4 is closed. The closed end of the filter box 4 is connected to the air outlet 3. The shell outlet 8 is located at the bottom of the square end of the filter box 4. The filter box 4 and the side opposite to the air outlet 3 are open. The partition 10 is located in the middle position inside the square end of the filter box 4. The partition 10 divides the square end of the filter box 4 into two parts.

[0025] Two slots 16 are welded symmetrically on the outside of the open end of the filter box 4, and connecting rods 17 are welded on the outside of the slots 16. The arc plate 11 is welded on the two connecting rods 17. The arc plate 11 is used to guide a small part of the airflow blown out from one screen 9 to the other screen 9, so as to realize backblowing and blow off the shell stuck on the screen 9.

[0026] There are two screens 9, both of which are inserted between the two slots 16. The two screens 9 correspond to the two parts of the filter box 4 divided by the partition 10, and the screens 9 are inserted on the filter box 4 through the slots 16. The screens 9 are inserted in the two slots 16, so that the screens 9 can be removed, so that the screens 9 are convenient to replace.

[0027] The rotating shaft 5 is located at one end of the partition 10, and the windshield 6 divides the closed end of the filter box 4 into two parts. The free end of the windshield 6 is close to the inner wall of the filter box 4, so that one side of the windshield 6 is connected to the air outlet 3 and the other side is blocked from the air outlet 3. In this way, the filter box 4 is divided into two air outlet channels by the windshield 6 and the partition 10. One air outlet channel is connected to the air outlet 3 and is used to filter the shell, and the other air outlet channel is blocked by the windshield 6 and is used to make the shell accumulated on the screen 9 fall and back-blown.

[0028] The upper and lower ends of the rotating rod 12 are both U-shaped, the bottom end of the frame 1 is located in the U-shaped portion of the upper end of the rotating rod 12, the hinge between the frame 1 and the rotating rod 12 is located in the U-shaped portion of the upper end of the rotating rod 12, and the wheel 13 is located in the U-shaped portion of the lower end of the rotating rod 12.

[0029] The support rod 14 is vertically welded to the upper end of the rotating rod 12 . The end of the support rod 14 connected to the rotating rod 12 is U-shaped. The inner cavity of the U-shaped part of the support rod 14 is connected to the inner cavity of the U-shaped part of the upper end of the rotating rod 12 .

[0030] The bottom end of the frame 1, the rotating rod 12, and the support rod 14 are all provided with through holes 18. The position of the through holes 18 on the frame 1 is located below the hinge between the frame 1 and the rotating rod 12. The positions of the through holes 18 on the rotating rod 12 and the support rod 14 correspond to the positions of the through holes 18 on the frame 1. The bolt pair 15 is inserted into the through holes 18 of the frame 1 and the rotating rod 12 to fix the rotating rod 12 on the frame 1. The rotating rod 12 and the support rod 14 can realize the switching of the wheels 13 and the support rod 14 to support the frame 1, so as to increase stability by using the support rod 14 to support during the working process, and the frame 1 is supported by the wheels 13 during the moving process, so as to facilitate the movement of the utility model.

[0031] The working principle of the utility model is:

[0032] When in use, the utility model is pushed to a designated position, the bolt pair 15 on one of the rotating rods 12 is removed, and then the rotating rod 12 is rotated to make the support rod 14 contact the ground, and then the bolt pair 15 is inserted into the through holes 18 on the frame 1 and the support rod 14, so that the support rod 14 is fixed to the frame 1, and the other rotating rods 12 are switched in the same way, so that the frame 1 can be supported by the support rod 14, thereby increasing the stability of the utility model during operation, and there is no need to use the wheels 13 with brakes.

[0033] After the switching is completed, the shelled wheat seeds are put into the sheller body 2. The wheat seeds are crushed in the sheller body 2 and then air-selected. The shell is blown to the air outlet 3 and enters the filter box 4 from the air outlet 3. The filter box 4 is divided into two air outlet channels by the wind shield 6 and the partition 10. One air outlet channel is connected to the air outlet 3, and the other air outlet channel is blocked by the wind shield 6. Therefore, the shell enters the channel connected to the air outlet 3 and is blown onto the screen 9. The shell is blocked by the screen 9, and a part of it is discharged from the shell bucket 8 under its own weight, and the other part is stuck on the screen 9 and accumulated on the screen 9 under the action of the fan.

[0034] After starting the motor 6, the motor 6 drives the rotating shaft 5 and the windshield 6 to rotate, so that the free end of the windshield 6 contacts the inner wall of the other side of the filter box 4, so that the air outlet channel is switched, and the shell enters another air outlet channel. By setting the time interval of the reciprocating rotation of the motor 6, the timed back and forth switching of the two air outlet channels can be realized. In this process, the shell on the screen 9 of the air outlet channel separated from the air outlet 3 falls into the shell outlet under the action of deadweight due to the absence of the blowing of the fan, and a small part of the shell is still stuck on the screen 9. At the same time, after the airflow of another air outlet channel is blown out from the screen 9, a part of the airflow is guided by the arc plate 11 to blow to the screen 9 with the shell stuck, so that the screen 9 is backblown, so that a small amount of shell stuck on the screen 9 is backblown into the shell bucket 8. This is repeated to prevent the shell from accumulating on the screen 9 and avoid clogging the mesh of the screen 9.
