DETAILED DESCRIPTION

[0031] The utility model will be further described below in combination with the drawings and embodiments.

[0032] A differential double-drum spike threshing and separating device, comprising a rack 1, a drum outer sieve 3 installed on the rack 1 for separating impurities and guiding and discharging materials;

[0033] A drum inner sieve 4 installed on the rack 1 for screening, the drum inner sieve 4 being arranged in the drum outer sieve 3;

[0034] A threshing roller 5 installed on the rack 1 for threshing, the threshing roller 5 being arranged inside the drum inner sieve 4;

[0035] A first power transmission box 6 and a second power transmission box 2, respectively installed on the rack 1, the first power transmission box 6 being used to provide power for the drum outer sieve 3, and the second power transmission box 2 being used to provide power for the drum inner sieve 4.

[0036] The rotating speeds of the first power transmission box 6 and the second power transmission box 2 are different, and the rotating directions thereof are opposite.

[0037] The rotating speeds of the threshing roller 5 and the drum inner sieve 4 are different, and the rotating directions thereof are opposite.

[0038] Specifically, the first power transmission box 6 and the second power transmission box 2 drive the outer drum sieve 3, the inner drum sieve 4 and the threshing roller 5 to work cooperatively by providing power with different rotating speeds and directions, so as to continuously thresh and separate the impurities of the material entering the device. The rotating speeds of the first power transmission box 6 and the second power transmission box 2 are different, and the rotating directions are opposite. The rotating speeds of the threshing roller 5 and the inner drum sieve 4 are different, and the rotating directions are opposite. Such arrangement enables the outer drum sieve 3 and the inner drum sieve 4 to rotate at different speeds and directions, thereby enhancing the separation effect of the material. The rotating speeds of the threshing roller 5 and the inner drum sieve 4 are different, and the rotating directions are opposite, which further promotes the threshing and separation process of the material in the device and improves the overall working efficiency and quality.

[0039] Specifically, due to the different rotating speeds and directions of the inner drum sieve 4 and the outer drum sieve 3 (for example, the inner drum sieve 4 rotates counterclockwise, the outer drum sieve 3 rotates clockwise, and the speeds are different), the fruits and impurities reaching the outer drum sieve 3 are separated under the action of such different speeds and directions.

[0040] The outer drum sieve 3 comprises an outer drum sieve support frame 301, a first rubber roller track 302, first guide vanes 303 and a scraper 304.

[0041] The outer drum sieve support frame 301 comprises a plurality of uniformly arranged first circular shafts and first support rings. The first support rings are fixedly connected to the first circular shafts. The first circular shafts are uniformly arranged along the radial direction of the support rings. The first support rings are uniformly arranged along the axial direction of the first circular shafts. A plurality of first guide vanes 303 are arranged on each first circular shaft. The first guide vanes 303 are equidistantly arranged along the axial direction of the first circular shafts. The first guide vanes 303 on adjacent first circular shafts are arranged in a staggered manner. The scraper 304 is arranged along the radial direction of the support rings. The scraper 304 is fixed to one of the support rings at one end. The outer drum sieve support frame 301 fixes the first rubber roller track 302. The first rubber roller track 302 is in transmission cooperation with a first power rubber roller 7. The first power rubber roller 7 is fixedly connected to the output end of the first power transmission box 6, thereby providing power for the outer drum sieve 3 to enable it to normally rotate for processing and guiding the material.

[0042] Specifically, the first power transmission box 6 drives the first rubber roller track 302 to rotate through the first power rubber roller 7, thereby driving the entire outer drum sieve 3 to rotate. The first guide vanes 303 on the outer drum sieve 3 play a certain guiding role for the material, so that the material moves in the appropriate direction. At this time, the scraper 304 is in a state of waiting for subsequent delivery of the separated material.

[0043] The inner drum sieve 4 comprises an inner drum sieve support frame 401, second guide vanes 402, a material end baffle 403 and a second rubber roller track 404.

[0044] The inner drum sieve support frame 401 comprises a second support ring and a second circular shaft, the second support ring is fixedly connected with the second circular shaft, the second circular shaft is uniformly arranged along the radial direction of the support ring, the second support ring is uniformly arranged along the axial direction of the second circular shaft, a plurality of second guide vanes 402 are arranged on each second circular shaft, the second guide vanes 402 are equidistantly arranged along the axial direction of the second circular shaft, the second guide vanes 402 on adjacent second circular shafts are arranged in a staggered manner, the material end baffle 403 is fixed on one second support ring at one end, the material end baffle 403 is arranged along the circumferential direction of the support ring, the material end baffle 403 is used to assist the scraper 304 of the outer drum sieve 3 to discharge material, the second rubber roller track 404 is fixed at the outer end of one second support ring at one end, the second rubber roller track 404 is in transmission cooperation with the second power rubber roller 701, the second power rubber roller 701 is fixed to the output end of the second power transmission box 2 to provide power for the inner drum sieve 4, so that the inner drum sieve 4 and the outer drum sieve 3 work cooperatively to realize effective screening and separation of the material.

[0045] Specifically, the larger impurities such as rhizomes in the material mixture make spiral motion towards the discharge end in the inner drum sieve 4, which is due to the rotation of the inner drum sieve 4 and the action of the second guide vanes 402 thereof, so that these larger impurities form a spiral trajectory under the action of centrifugal force and flow guide and move towards the discharge end.

[0046] The threshing roller 5 comprises a spike rod 501, spikes 502, a spike rod adjusting plate 503, a rotating shaft 504, a width plate 505, a clogging clearing knife 506, and a transmission pulley 507.

[0047] The rotating shaft 504 is connected with the frame 1, and the rotating shaft 504 is fixed with a plurality of uniformly arranged web plates 505 arranged along the axial direction of the rotating shaft 504. A plurality of uniformly arranged toothed rod adjusting plates 503 are arranged on each toothed rod 501, and the toothed rod adjusting plates 503 are arranged on the web plates 505. The toothed rod adjusting plates 503 are arranged on the web plates 505 through bolts and nuts. The toothed rods 501 are arranged along the radial direction of the web plates 505. A plurality of uniformly arranged teeth 502 are arranged on each toothed rod 501 along the axial direction of the toothed rod 501. One end of the rotating shaft 504 is fixedly connected with the transmission belt pulley 507, and the toothed rods 501 at both ends are arranged in a staggered manner. The unblocking knife 507 is arranged on the toothed rod adjusting plate 503 at one end of the transmission belt pulley 507 in a spiral manner. The threshing roller 5 is drivingly connected with the output end of the first power transmission box 6 through a belt and a belt pulley, so that the threshing roller 5 can rotate at a high speed during operation of the device, the material is threshed by the teeth 502, and the material is prevented from being blocked by the unblocking knife 507, so that the operation is smoothly performed.

[0048] The length of the toothed rod 501 on the threshing roller 5 can be set as required, and the number of the toothed rod 501 can also be set as required.

[0049] The power of the threshing roller 5 is transmitted to the transmission belt pulley 507 of the threshing roller 5 through a belt and a power belt pulley fixedly connected with the output shaft of the first power transmission box 6. The belt and the power belt pulley are prior art, and will not be described in detail.

[0050] The unblocking knife 506 prevents the material from blocking the teeth 502 during operation of the threshing roller 5, so that the device can be stably operated, so as to meet the threshing and separating requirements of oil bean and other materials, and also has a good threshing and separating effect on other materials with similar characteristics.

[0051] Specifically, the main threshing component of the threshing roller 5, the tooth 502, has a clear disturbance and crushing effect on the material mixture compared with the original conveying spiral auger, and has the characteristics of threshing and straw removal.

[0052] Specifically, the threshing roller 5 rotates at high speed under the drive of the first power transmission box 6, and the tines 502 of the threshing roller 5 strike and rub against the surface of the inner cylinder screen 4, because the rotation speeds of the threshing roller 5 and the inner cylinder screen 4 are different and the rotation directions are opposite, the relative movement further threshes and refines the blocky mixture during the migration process. For example, when the threshing roller 5 rotates clockwise at high speed and the inner cylinder screen 4 rotates counterclockwise at low speed, the material between them is continuously subjected to forces from different directions and speeds, and the particles in the material are gradually separated out. At the same time, the material end baffle 403 at one end of the inner cylinder screen 4 plays a certain blocking and auxiliary flow guiding role during the migration of the material to the tail end, preventing the material from overflowing from the end of the inner cylinder screen 4 too early, ensuring that the material has enough time and space to undergo the threshing and separating process in the inner cylinder screen 4. During the rotation of the inner cylinder screen 4, the tines 502 of the threshing roller 5 continue to strike and comb these larger impurities, further dispersing the impurities, so that the cattail fruit stems and most of the fiber material and other impurities are discharged through the tail end of the cylinder, realizing a more thorough threshing and separating operation of the cattail material mixture.

[0053] Specifically, the material and part of the impurities separated by the inner cylinder screen 4 are transported to the discharge end of the outer cylinder screen 3 through the first flow guiding vane 303 on the surface of the outer cylinder screen 3. During the transportation process, the material and the impurities are further separated, and the separated and refined impurities are returned to the inner cylinder screen 4 and discharged outside (impurities smaller than the screen hole are directly discharged through the screen hole), and the material continues to be transported to the discharge end of the outer cylinder screen 3 under the action of the first flow guiding vane 303. The material end baffle 403 of the inner cylinder screen 4 prevents the material from accumulating and returning to the inner cylinder screen 4, causing loss, and on the other hand, the material end baffle 403 cooperates with the scraper 304 to send the material to the discharge port.

[0054] The said unblocking knife 506 is arc-shaped, and the tine rod adjusting plate 503 is hollow.

[0055] Taking the threshing and separating of cattail as an example, the working process of the differential speed double-cylinder tine threshing and separating device is further described, but the threshing and separating materials it is applicable to are not limited to this example.

[0056] The material mixture of cyperus esculentus fruit, sand and the like is fed into the differential double-roller peg tooth threshing and separating device by a feeding device (not shown, using prior art, not described again), and the sand, small stems and the like are discharged out of the machine through the screen holes of the outer screen 3 and the inner screen 4, and the cyperus esculentus fruit and the blocky mixture of stems and the like are moved to the tail end of the roller in the inner screen 4 under the action of the threshing roller 5 and the flow guide blades on the surface of the inner screen 4, and in the moving process, the blocky mixture is further threshed and refined under the beating and rubbing action of the threshing roller 5 and the inner screen 4, and the cyperus esculentus fruit and part of the impurities with the same particle size as the cyperus esculentus fruit are separated and refined, and the fruit and the impurities are further separated due to the different rotating speeds of the inner screen 4 and the outer screen 3, and the cyperus esculentus fruit is moved to the discharge end under the action of the flow guide blades on the surface of the outer screen 3, and the outer screen 3 is provided with a scraper 304 at the discharge end to send the material to the discharge port, and at the same time, the roots and the like in the material mixture make spiral motion to the discharge end in the inner screen 4, and are further scattered under the action of the threshing roller 5 and the flow guide blades on the inner screen 4, and the cyperus esculentus fruit, stems and most of the fiber material and the like are discharged from the tail end of the roller, so that the threshing and separating operation of the cyperus esculentus material mixture is realized.

[0057] It should be noted that the device is suitable for threshing and separating not only cyperus esculentus, but also other crops with similar material characteristics, and has good threshing and separating effect, and the running parameters (such as the rotating speed of the power transmission box) of the device can be adjusted according to the actual situation of different crops to achieve the best threshing and separating effect.

[0058] The above disclosure is only a specific embodiment of the utility model, but the utility model is not limited to this, and any change that can be thought of by any person skilled in the art should fall within the protection scope of the utility model.
