Description

Technical Field

[0001] This invention relates to the field of threshing equipment technology, and more particularly to a sunflower threshing device. Background Technology

[0002] After sunflower seeds mature, they need to be threshed to fall from the sunflower head. The traditional threshing method is to thresh them by beating. While manual beating allows for better control of the beating force, it is labor-intensive, inefficient, and difficult to meet the needs of large-scale threshing. Using machines to thresh them makes it difficult to control the beating force, and the sunflower seeds are easily broken during the beating process, affecting the quality of threshing. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the prior art by providing a sunflower threshing device.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0005] A sunflower threshing device includes a housing, the upper end of which is provided with a feed inlet;

[0006] A conveying assembly, located above the housing, is used to convey sunflowers into the housing;

[0007] Two extrusion plates are provided, which are slidably disposed within the housing, and the two extrusion plates are symmetrically arranged.

[0008] A threshing plate is rotatably mounted on the extrusion plates, and the threshing plate is located between the two extrusion plates;

[0009] A baffle is slidably disposed within the housing, and the baffle is located between the two threshing plates.

[0010] Preferably, a plurality of plug-in rods are fixedly provided on the threshing plate, and the end of the plug-in rod away from the threshing plate has a conical structure.

[0011] Preferably, a guide rod is fixedly disposed inside the housing, the guide rod is horizontally disposed, and the extrusion plate is slidably disposed on the guide rod.

[0012] Preferably, a compression cylinder is fixedly installed inside the housing, and the piston rod of the compression cylinder is fixedly connected to the compression plate for driving the compression plate to slide horizontally inside the housing.

[0013] Preferably, a rotary motor is fixedly mounted on the extrusion plate, and the output shaft of the rotary motor is fixedly connected to the threshing plate to drive the threshing plate to rotate.

[0014] Preferably, the two threshing plates rotate in opposite directions.

[0015] Preferably, a guide plate is fixedly provided at the upper end of the casing, and the guide plate is inclined to allow the sunflower to fall vertically into the casing.

[0016] Preferably, the conveying assembly includes a conveyor, the output end of which is located above the feed inlet, and a conveying cover and a storage bin are fixedly installed on the conveyor. Both the conveying cover and the storage bin are located above the conveyor and are connected to each other.

[0017] Preferably, the bottom of the housing is provided with a first discharge port, the side wall of the housing is provided with a second discharge port, a screening plate is provided inside the housing, the screening plate is located below the extrusion plate, the first discharge port is located below the screening plate, and the second discharge port is located on one side of the screening plate.

[0018] Preferably, the screening plate is inclined.

[0019] The beneficial effects of adopting the above technical solution are as follows:

[0020] In this invention, sunflowers are conveyed by a conveying assembly and fall into the machine housing from the feed inlet. The sunflowers fall vertically and land between two threshing plates. A baffle prevents the sunflowers from falling further. Then, a pressing cylinder moves the pressing plates closer together, clamping and fixing the sunflowers between the two threshing plates. The baffle then slides to one side of the two threshing plates, and a rotary motor rotates the two threshing plates, separating the sunflowers and causing the sunflower seeds to fall onto a screening plate below the threshing plates. The sunflower seeds pass through the screening plate and are discharged from the first outlet, while the sunflowers fall onto the screening plate and are discharged from the second outlet. The threshing process avoids damaging the sunflowers, thus protecting the sunflower seeds, preventing them from breaking, and improving their quality. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] like Figures 1 to 5As shown, a sunflower threshing device includes a housing 1, with a feed inlet at the upper end of the housing 1. A conveying assembly is located above the housing 1 for conveying sunflowers into the housing 1. Two extrusion plates 2 are horizontally slidably arranged inside the housing 1, allowing them to slide towards or away from each other. Two threshing plates 3 are rotatably arranged on the extrusion plates 2, one on each of the two extrusion plates 2, and located between the two extrusion plates 2. A baffle 4 is also horizontally slidably arranged inside the housing 1, located at the lower part between the two threshing plates 3, to block the sunflowers and prevent them from falling below the threshing plates 3 before threshing. At the same time, the baffle 4, located between the two threshing plates 3, can also limit the distance between the two threshing plates 3, preventing the sunflowers from being crushed due to excessive proximity.

[0033] In this invention, sunflowers are conveyed by the conveying assembly and enter the machine housing 1 through the feed inlet at the top of the housing 1. Upon entry, the sunflowers are in a vertical position and fall between the two threshing plates 3. At this point, the baffle 4 is positioned between the two threshing plates 3, thus preventing unthreshed sunflowers from falling below the threshing plates 3. Subsequently, the two pressing plates 2 slide towards each other until the two threshing plates 3 clamp the sunflowers, preventing them from falling further. The baffle 4 then slides horizontally to one side of the threshing plates 3, clamping the sunflowers. Then, the two threshing plates 3 rotate in opposite directions. During the rotation, the threshing plates 3 thresh the sunflower seeds on the sunflower disc, causing the sunflower seeds to fall to the lower part of the machine casing 1, thus completing the threshing operation. After threshing, the two pressing plates 2 slide to the side away from each other, and finally the sunflower seeds fall to the lower part of the machine casing 1 for collection. Therefore, in this invention, the detachment of sunflower seeds can be completed without knocking, which can greatly reduce damage to the sunflower seeds and avoid the sunflower seeds breaking due to excessive knocking force, thereby improving the quality of sunflower seeds.

[0034] It should be noted that, as Figure 2 As shown, the baffle 4 is driven to slide by a sliding cylinder fixedly installed on the outer wall of the housing 1. One end of the baffle 4 is fixedly connected to the piston rod of the sliding cylinder. The baffle 4 slides horizontally by the extension and retraction of the piston rod of the sliding cylinder.

[0035] In one embodiment of the present invention, such as Figure 5As shown, a plurality of connecting rods 5 are fixedly installed on the threshing plate 3. The end of the connecting rod 5 away from the threshing plate 3 is a conical structure. In this embodiment, the sunflower seeds are located on one side of the sunflower disc. When the sunflowers fall between the two threshing plates 3, as the two threshing plates 3 move closer together, they can clamp and fix the sunflower disc. The connecting rod 5 located on the back side of the sunflower disc can be inserted into the sunflower disc, while the connecting rod 5 on the other threshing plate 3 is inserted between the sunflower seeds. As the two threshing plates 3 rotate, the connecting rod 5 inserted into the threshing plate 3 on the side of the sunflower disc can drive the sunflower disc to rotate. The connecting rod 5 on the other threshing plate 3 knocks the sunflower seeds off and peels them off during the rotation, thus completing the threshing of the sunflowers.

[0036] It should be noted that the length of the connecting rod 5 is less than the length of the sunflower seed. Therefore, the connecting rod 5 located on the side of the sunflower seed can knock the sunflower seed off during rotation without damaging the sunflower disc, thereby reducing the amount of sunflower disc debris mixed in with the sunflower seed and improving the cleanliness of the sunflower seed.

[0037] In one embodiment of the present invention, such as Figure 4 and Figure 5 As shown, when threshing sunflowers, the insert rod 5 needs to be inserted into the side of the sunflower disc away from the sunflower seeds. Therefore, after threshing, as the two threshing plates 3 move further apart, the sunflower disc is not easy to fall off the threshing plate 3. Therefore, in order to allow the sunflower disc to fall off the threshing plate 3, a through-hole 16 is provided on the threshing plate 3. A push-out cylinder 17 is fixedly installed on the side of the extrusion plate 2 away from the threshing plate 3. The piston rod of the push-out cylinder 17 can extend and retract within the insertion hole 16. When the sunflowers are threshed, the piston rod of the push-out cylinder 17 retracts, and the insert rod 5 can be inserted into one side of the sunflower disc. After threshing, as the two threshing plates 3 move further apart, the piston rod of the push-out cylinder 17 extends, passes through the insertion hole 16, and pushes the sunflower disc off the insert rod 5, so that the sunflower disc can fall to the lower part of the machine casing 1.

[0038] In one embodiment of the present invention, a rotary motor 8 is fixedly installed on the extrusion plate 2, and the output shaft of the rotary motor 8 is fixedly connected to the threshing plate 3 for driving the threshing plate 3 to rotate. In this embodiment, the rotary motor 8 is a servo motor with high precision, so that the insertion hole 16 corresponds to the piston rod position of the ejector cylinder 17 after the threshing plate 3 stops rotating each time, so that the piston rod of the ejector cylinder 17 can pass through the insertion hole 16 to eject the sunflower disc.

[0039] In one embodiment of the present invention, a guide rod 6 is fixedly provided inside the housing 1. The guide rod 6 is horizontally arranged, and the extrusion plate 2 is slidably arranged on the guide rod 6. In this embodiment, there are four guide rods 6, which are respectively located at the four corners of the extrusion plate 2. During the sliding process of the extrusion plate 2, the guide rod 6 can play a guiding role, so that the extrusion plate 2 can slide horizontally along the length direction of the guide rod 6, making the sliding of the extrusion plate 2 more stable.

[0040] It should be noted that the upper end of the extrusion plate 2 is provided with an inclined connecting plate. The upper surface of the connecting plate abuts against the top plate of the casing 1. The distance between the upper ends of the two connecting plates is greater than the distance between the lower ends of the two connecting plates. Therefore, during the process of sunflower falling, it can prevent the sunflower from falling to the outside of the extrusion plate 2, and at the same time guide the sunflower to fall between the two extrusion plates 2.

[0041] In one embodiment of the present invention, a compression cylinder 7 is fixedly installed inside the housing 1. The cylinder barrel of the compression cylinder 7 is fixedly installed on the side wall of the housing 1. The piston rod of the compression cylinder 7 is fixedly connected to the compression plate 2. By extending and retracting the piston rod of the compression cylinder 7, the compression plate 2 can be driven to slide horizontally along the guide rod 6, thereby clamping the sunflower.

[0042] like Figure 6 As shown, in another embodiment, a lead screw 18 is rotatably installed inside the housing 1, and a drive motor 19 is fixedly installed outside the housing 1. The drive motor 19 is connected to the lead screw 18 for driving the lead screw 18 to rotate. The lead screw 18 is symmetrically provided with bidirectional threads, and the two extrusion plates 2 are respectively threaded to the two threaded parts of the lead screw 18. Therefore, the lead screw 18 can drive the two extrusion plates 2 to move towards each other or away from each other during rotation.

[0043] In one embodiment of the present invention, two guide plates 9 are fixedly provided at the upper end of the housing 1. The guide plates 9 are inclined and symmetrically arranged. The distance between the upper ends of the two guide plates 9 is greater than the distance between the lower ends of the two guide plates 9. The feed inlet is located between the two guide plates 9. In this embodiment, the sunflowers falling from the conveying component can be guided by the two guide plates 9 so that the sunflowers can fall vertically into the housing 1, thereby clamping the sunflowers between the two threshing plates 3 for threshing operation. The two ends of the two guide plates 9 are fixedly provided with sealing plates to prevent the sunflowers from falling to the outside of the housing 1.

[0044] In one embodiment of the present invention, the conveying assembly includes a conveyor 10, the output end of which is located above the feed inlet. A conveying cover 11 and a storage bin 12 are fixedly installed on the conveyor 10. Both the conveying cover 11 and the storage bin 12 are located above the conveyor 10 and are connected to each other. A conveying channel is formed between the conveying cover 11 and the conveyor 10 to facilitate the conveying of sunflowers. The height of the conveying channel is sufficient to allow one sunflower to pass horizontally. The bottom of the storage bin 12 is an open end, and the threshing personnel can put the sunflowers to be threshed into the storage bin 12. After entering the storage bin 12, the sunflowers can fall from the bottom of the storage bin 12 onto the conveyor 10 and be conveyed by the conveyor 10. Finally, the sunflowers can fall from the output end of the conveyor 10 into the feed inlet of the casing 1.

[0045] It should be noted that an inclined transition plate is provided between the storage bin 12 and the conveyor cover 11, which allows the sunflowers in the storage bin 12 to smoothly enter the conveying channel below the conveyor cover 11, and avoids the sunflowers from getting stuck between the storage bin 12 and the conveyor cover 11.

[0046] Furthermore, the conveyor 10 includes a frame 20 and a conveyor belt 21 rotatably mounted on the frame 20. A fixing bar 22 is fixedly mounted on the conveyor belt 21. During the rotation of the conveyor belt 21, the fixing bar 22 can push the sunflowers forward to prevent the sunflowers from slipping on the conveyor belt.

[0047] In one embodiment of the present invention, a first discharge port 13 is provided at the bottom of the casing 1, a second discharge port 14 is provided on the side wall of the casing 1, and a sieve plate 15 is fixedly installed inside the casing 1. The sieve plate 15 has a plurality of sieve holes evenly distributed on it. The sieve plate 15 is located below the extrusion plate 2, the first discharge port 13 is located below the sieve plate 15, and the second discharge port 14 is located on one side of the sieve plate 15. In this embodiment, the sunflower seeds after threshing fall onto the sieve plate 15 and can pass through the sieve holes on the sieve plate 15 to the first discharge port 13 at the bottom of the casing 1 for collection outside the casing 1. The sunflower discs fall onto the sieve plate 15 and are discharged from the second discharge port 14.

[0048] In one embodiment of the present invention, the sieve plate 15 is inclined and the second discharge port 14 is located at the lowest point of the sieve plate 15. Therefore, the sunflower disc can slide down along the sieve plate 15 and be discharged from the second discharge port 14, while the sunflower seeds can pass through the sieve holes on the sieve plate 15 and fall to the first discharge port 13 for discharge during the sliding process.

[0049] like Figure 7 As shown, in another embodiment of the present invention, an installation strip 23 is fixedly provided on the side wall inside the housing 1. The installation strip 23 is located below the screening plate 15. The screening plate 15 is slidably disposed inside the housing 1. A spring 24 is provided between the screening plate 15 and the installation strip 23. One end of the spring 24 is fixedly connected to the installation strip 23, and the other end is fixedly connected to the lower end face of the screening plate 15. A vibration motor 25 is fixedly provided on the lower end face of the screening plate 15. Therefore, after the vibration motor 25 is started, the screening plate 15 can vibrate up and down. Sunflower seeds falling on the screening plate 15 can quickly fall below the screening plate 15 under the vibration state to prevent material accumulation. The sunflower discs are quickly discharged from the second discharge port 14 under the vibration condition of the screening plate 15.

[0050] It should be noted that multiple blocking strips 26 are fixedly provided on the upper end face of the screening plate 15. The blocking strips 26 can block the sunflower seeds and prevent the vibration from causing the sunflower seeds to be discharged from the second discharge port 14.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
