Combined oat threshing device

Abstract

This invention provides a composite oat threshing device. Compared with the prior art, during oat threshing, harvested oat seedlings are fed into the feed inlet. At this time, the threshing mechanism rotates to thresh the oat seedlings. Simultaneously, the air inlet mechanism guides airflow into the interior of the threshing mechanism. The airflow diffuses outward through the threshing mechanism. When the airflow passes through the gaps between the oat seedlings, it blows out light dust and oat grains mixed inside the oat seedlings, improving the threshing effect and reducing the number of oat grains mixed inside the oat seedlings. At the same time, the light dust is blown out. Because the light dust is lighter, it will be discharged from the higher outlet with the airflow, making the oat grains cleaner. After the oat grains fall through the filter frame onto the surface of the slope, the airflow flows over the surface of the slope. Under the action of their own gravity, the oat grains roll off the surface of the slope. At this time, the airflow blows the light debris on the slope, causing the light debris to be discharged from the discharge trough into the discharge port with the airflow.

Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment, and in particular to a composite oat threshing device. Background Technology

[0002] Oats are a globally cultivated crop. However, existing oat threshing devices thresh oat seedlings inside the threshing channel, but the seedlings contain some oat grains. Furthermore, after threshing, the oat grains are mixed with light dust and impurities, affecting their quality and requiring subsequent dust and impurity removal. Therefore, a composite oat threshing device is proposed. Summary of the Invention

[0003] To address at least one of the aforementioned technical shortcomings, this invention provides a composite oat threshing device, comprising a shell, a top cover fixedly connected to the top of the shell, a threshing mechanism for threshing inside the shell, a filter frame for filtering oat grains located directly below the threshing mechanism, a feed inlet at the head of the shell, a discharge outlet at the tail of the shell, an air inlet mechanism at the head of the top cover, the air outlet of the air inlet mechanism being coaxially aligned with the threshing mechanism, a ramp fixedly connected inside the shell directly below the filter frame, a gap forming between the bottom of the ramp and the inner wall of the shell, the gap being directly below the feed inlet, a grain bin placed directly below the gap, and a waste removal trough penetrating the discharge outlet at the top of the ramp.

[0004] Furthermore, the threshing mechanism includes a motor fixedly connected to the outer wall of the head of the outer shell. The output shaft of the motor is provided with a transmission shaft rotatably connected to the inside of the outer shell. A frustum cylinder is fixedly connected to the transmission shaft. A number of inclined rods are evenly distributed in a circular pattern at the tail of the frustum cylinder. The tails of the inclined rods are converging. A number of threshing rods are provided on the inclined rods. A spiral plate is provided on the outer wall of the frustum cylinder. A stirring rod is fixed to the outer wall of the frustum cylinder between the gaps of the spiral plate.

[0005] Furthermore, the air intake mechanism includes an air guide ring fixedly connected to the inner wall of the head of the outer casing. The air guide ring is coaxially arranged with the frustum cylinder. A powerful fan is provided on the air guide ring, and a C-shaped air intake pipe is rotatably connected to the air intake end of the powerful fan.

[0006] Furthermore, the top cover has a cone-shaped mesh cylinder arranged in a semi-circle parallel to the inclined rod inside. The cone-shaped mesh cylinder and the top cover form a ash discharge cavity. The tail of the top cover has several ash discharge pipes that penetrate the ash discharge cavity. The cone-shaped mesh cylinder has several spiral blades arranged in a 180° angle evenly inside.

[0007] Furthermore, the filter frame includes two end plates, and several filter rods are evenly distributed in a semi-circular pattern between the two end plates. The filter rods are arranged parallel to the inclined rods, and the filter grooves are formed between adjacent filter rods. The filter grooves are wide at the head and narrow at the tail, and the end plate at the tail is flush with the front end of the discharge port.

[0008] Furthermore, it is installed on a harvester, and the harvester's feed channel is connected to the feed inlet.

[0009] Furthermore, the outer wall of the filter rod is fitted with a rotatable metal tube.

[0010] Furthermore, the air inlet end of the C-shaped air inlet pipe is flush with the harvester's cab.

[0011] Furthermore, the interior of the grain silo is divided into an upper silo and a lower silo by an electric valve. The lower silo is cone-shaped, and its discharge pipe is connected to the feed pipe of the harvester's elevator.

[0012] Beneficial effects:

[0013] 1. Compared with the prior art, in the process of threshing oats, the harvested oat seedlings are fed in through the feed inlet. At this time, the threshing mechanism rotates to thresh the oat seedlings. At the same time, the air inlet mechanism guides the airflow into the interior of the threshing mechanism. The airflow passes through the threshing mechanism and diffuses outward. When the airflow passes through the gaps between the oat seedlings, it blows out the light dust and the oat grains mixed inside the oat seedlings, thereby improving the threshing effect and reducing the number of oat grains mixed inside the oat seedlings. At the same time, the light dust is blown out. Because the light dust is lighter, it will be discharged from the higher outlet with the airflow, making the oat grains cleaner. After the oat grains fall through the filter frame to the surface of the slope, the airflow flows over the surface of the slope. Under the action of their own gravity, the oat grains roll off the surface of the slope. At this time, the airflow blows the light debris on the slope, causing the light debris to be discharged from the discharge trough into the discharge port with the airflow.

[0014] 2. The powerful blower uses existing technology to generate airflow. The airflow enters through the C-shaped air inlet pipe, passes through the powerful blower, and is then blown into the interior of the truncated cone through the air guide ring. The airflow passes through the gaps of several inclined rods. At this time, the airflow passes through the gaps of the oat fuzz, blowing out the light dust and grains mixed in with the oat fuzz, improving the threshing effect of oats while effectively removing light dust.

[0015] 3. During threshing, the oat grains threshed from the oat seedlings are discharged from the filter tank. At this time, several filter rods form a semi-circular filter structure with a low head and a high tail. After the oat grains are threshed, they move towards the head end, allowing them to move to the appropriate filter tank for discharge.

[0029] Please refer to Figures 1 to 11 ;

[0030] This embodiment provides a composite oat threshing device, referenced... Figures 2 to 4The device includes an outer casing 1, a top cover 2 fixedly connected to the top of the outer casing 1, a threshing mechanism 3 for threshing inside the outer casing 1, a filter rack 4 for filtering wheat grains located directly below the threshing mechanism 3, a feed inlet 101 at the head of the outer casing 1, a discharge outlet 102 at the tail of the outer casing 1, and an air inlet mechanism 5 at the head of the top cover 2. The air outlet of the air inlet mechanism 5 is coaxially arranged with the threshing mechanism 3. (Reference) Figure 4 Inside the outer shell 1, a ramp 103 is fixedly connected directly below the filter frame 4. A gap is formed between the bottom end of the ramp 103 and the inner wall of the outer shell 1, and the gap is located directly below the feed inlet 101. A grain bin 6 is placed directly below the gap. A waste discharge trough 104 that penetrates the discharge outlet 102 is provided at the top of the ramp 103.

[0031] In practice, when threshing oats, the harvested oat seedlings are fed in through the inlet 101. At this time, the threshing mechanism 3 rotates to thresh the oat seedlings. Simultaneously, the air inlet mechanism 5 guides the airflow into the interior of the threshing mechanism 3. The airflow passes through the threshing mechanism 3 and diffuses outward. When the airflow passes through the gaps between the oat seedlings, it blows out the light dust and oat grains mixed inside the oat seedlings, improving the threshing effect and reducing the number of oat grains mixed inside the oat seedlings. At the same time, the light dust is blown out. Because the light dust is lighter, it will be discharged from the higher outlet with the airflow, making the oat grains cleaner. When the oat grains fall through the filter frame 4 onto the surface of the slope 103, the airflow flows over the surface of the slope 103. Under the action of its own gravity, the oat grains roll off the surface of the slope 103. At this time, the airflow blows the light debris on the slope 103, causing the light debris to be discharged from the discharge trough 104 into the discharge port 102 for discharge.

[0032] Further reference Figures 5 to 7 The threshing mechanism 3 includes a motor 301 fixedly connected to the outer wall of the head of the outer shell 1. The output shaft of the motor 301 is provided with a transmission shaft 302 rotatably connected to the inside of the outer shell 1. A frustum cylinder 303 is fixedly connected to the transmission shaft 302. A plurality of inclined rods 304 are evenly distributed in a circular pattern at the tail of the frustum cylinder 303. The tails of the inclined rods 304 are converging. A plurality of threshing rods 305 are provided on the inclined rods 304. A spiral plate is provided on the outer wall of the frustum cylinder 303. A stirring rod is fixed to the outer wall of the frustum cylinder 303 between the gaps of the spiral plate.

[0033] In practice, during threshing, the motor 301 drives the transmission shaft 302 to rotate, causing the frustum cylinder 303 and several inclined rods 304 to rotate. The threshing rod 305 threshes the oat seedlings, forming a threshing channel between the threshing rod 305, the filter frame 4, and the top cover 2. The threshing channel is a frustum cylinder structure, wide at the head and narrow at the tail. Under the push of the stirring rod, the oat seedlings fed into the feed inlet 101 are fed into the gap of the spiral plate. The spiral plate continuously feeds the oat seedlings into the threshing channel.

[0034] Further reference Figure 9 The air intake mechanism 5 includes an air guide ring 501 fixedly connected to the inner wall of the head of the outer shell 1. The air guide ring 501 is coaxially arranged with the frustum cylinder 303. A powerful fan 502 is provided on the air guide ring 501. A C-shaped air intake pipe 503 is rotatably connected to the air intake end of the powerful fan 502.

[0035] In practical implementation, the powerful blower 502 adopts existing technology. The powerful blower 502 generates airflow, which enters from the C-shaped air inlet pipe 503, passes through the powerful blower 502, and then passes through the air guide ring 501 and is blown into the interior of the truncated cone 303. The airflow passes through the gaps of several inclined rods 304. At this time, the airflow passes through the gaps of the oat hairs, blowing out the light dust and grains mixed in with the oat hairs, improving the threshing effect of oats while effectively removing light dust.

[0036] Further reference Figure 11 The top cover 2 has a cone-shaped mesh cylinder 201 arranged in a semicircle parallel to the inclined rod 304 inside. The cone-shaped mesh cylinder 201 and the top cover 2 form a ash discharge cavity 202. The tail of the top cover 2 is provided with several ash discharge pipes 204 that penetrate the ash discharge cavity 202. The cone-shaped mesh cylinder 201 is uniformly provided with several spiral blades 203 arranged at 180° inside.

[0037] In practice, during threshing, the airflow passes through the oat seedlings and then through the conical mesh cylinder 201. The airflow carrying light dust enters the ash discharge cavity 202 and is then discharged from the ash discharge pipe 204. At the same time, under the action of several spiral blades 203, the oat seedlings can be slowly pushed towards the tail end while being threshed.

[0038] Further reference Figure 8 The filter frame 4 includes two end plates 401, and several filter rods 402 are evenly arranged in a semi-circular pattern between the two end plates 401. The filter rods 402 are arranged parallel to the inclined rods 304. The filter groove is formed between adjacent filter rods 402. The filter groove is wide at the head and narrow at the tail. The end plate 401 at the tail is flush with the front end of the discharge port 102.

[0039] In practice, during threshing, the oat grains threshed from the oat seedlings are discharged from the filter tank. At this time, several filter rods 402 form a semi-circular filter structure with a low head and a high tail. After the oat grains are threshed, they move towards the head end, allowing them to move to the appropriate filter tank for discharge.

[0040] Further reference Figure 1 It is installed on the harvester 7, and the feed channel of the harvester 7 is connected to the feed inlet 101;

[0041] In practice, the entire device can be installed on a harvester for use.

[0042] Furthermore, the outer wall of the filter rod 402 is fitted with a rotatable metal tube;

[0043] In practice, the filter tank formed by adjacent filter rods 402 can be rotated through the metal tube to prevent wheat grains from getting stuck inside the filter tank.

[0044] Furthermore, the air inlet end of the C-type air inlet pipe 503 is flush with the cab of the harvester 7;

[0045] In practice, during threshing, airflow enters through the C-type air inlet 503. When the C-type air inlet 503 is flush with the cockpit, the airflow can cool the driver and improve the driver's working comfort.

[0046] Furthermore, the interior of the grain bin 6 is divided into an upper bin and a lower bin by an electric valve. The lower bin is cone-shaped, and its discharge pipe is connected to the feed pipe of the harvester 7's elevator.

[0047] In practice, the elevator will remove the wheat grains from inside the grain bin 6 for easy bagging and packaging.
