DETAILED DESCRIPTION

[0065] The stem and ear combined harvesting type corn harvester straw automatic packaging device will be further described in detail in combination with the accompanying drawings, but not as a limitation to the present application.

[0066] As shown in Figures 1 to 22 A stem and ear combined harvesting type corn harvester straw automatic packaging device, comprising a shell 1 with a feeding assembly and a discharge port 101, the shell 1 is internally provided with a primary wrapping film assembly, a support assembly, a wrapping film supply assembly, a transfer assembly and a secondary wrapping film assembly.

[0067] As shown in Figure 8As shown, the feeding assembly comprises a feeding bin 2, which is sequentially provided with a feeding port 201, a cylindrical cavity 202, a guide groove 203 and a discharge pipe 204 from top to bottom. The bottom surface of the guide groove 203 is inclined, and the discharge pipe 204 is connected with the lowest part of the bottom surface of the guide groove 203. The bottom plate of the feeding port 201 is an inclined plate, which is connected with the cylindrical cavity 202 through the inclined plate.

[0068] A rotating drum 206 is arranged inside the cylindrical cavity 202, and the outer diameter of the rotating drum 206 is the same as the inner diameter of the cylindrical cavity 202. A plurality of storage grooves 207 are concavely arranged on the circumferential surface of the rotating drum 206, and the storage grooves 207 have the same volume and are arranged in a ring array around the axis of the rotating drum 206. The width of the open upper and lower ends of the cylindrical cavity 202 is equal to the width of the storage grooves 207.

[0069] A first motor 209 is fixed outside the feeding bin 2 to drive the rotating drum 206 to rotate. In order to facilitate the arrangement of the first motor 209, a second sprocket 2010 is fixed to the output shaft of the first motor 209. The rotating shaft end of the rotating drum 206 penetrates to the outside of the feeding bin 2 and is fixed with a first sprocket 208. The first sprocket 208 and the second sprocket 2010 are connected through a chain 2011.

[0070] In use, the feeding port 201 is connected with the discharge port of the existing stem and ear combined corn harvester. The crushed straw discharged by the blowing fan is directly thrown into the feeding bin 2. In order to avoid the diffusion of the crushed straw powder into the air, the discharge port of the blowing fan is connected with the feeding port 201 through a flexible pipeline. A filter screen plate corresponding to the feeding port 201 is arranged on the end surface of the feeding bin 2 away from the blowing fan. The filter screen plate can retain the straw, and the airflow generated by the blowing fan can be discharged through the filter screen plate.

[0071] The storage grooves 207 on the rotating drum 206 are used to realize the function of quantitative packaging of the straw. The straw filled in each storage groove 207 is the amount of straw of a final straw package 52. The rotation of the rotating drum 206 is realized by opening the first motor 209 at a constant interval. In order to control the angle of each rotation of the rotating drum 206, the first motor 209 is a servo motor. The angle of each rotation of the rotating drum 206 is the angle occupied by a single storage groove 207. In this way, after each time the first motor 209 stops rotating, the storage groove 207 directly above is arranged upwardly and connected with the feeding port 201, the storage groove 207 directly below is arranged downwardly and connected with the guide groove 203, and the remaining storage grooves 207 are covered by the inner wall of the cylindrical cavity 202.

[0072] A first motor 209 is fixed outside the feeding bin 2 to drive the rotating drum 206 to rotate. In order to facilitate the arrangement of the first motor 209, a second sprocket 2010 is fixed to the output shaft of the first motor 209. The rotating shaft end of the rotating drum 206 penetrates to the outside of the feeding bin 2 and is fixed with a first sprocket 208. The first sprocket 208 and the second sprocket 2010 are connected through a chain 2011. Figure 10 and Figure 11 As shown, the first motor 209 is fixed outside the feeding bin 2 to drive the rotating drum 206 to rotate. In order to facilitate the arrangement of the first motor 209, a second sprocket 2010 is fixed to the output shaft of the first motor 209. The rotating shaft end of the rotating drum 206 penetrates to the outside of the feeding bin 2 and is fixed with a first sprocket 208. The first sprocket 208 and the second sprocket 2010 are connected through a chain 2011.

[0073] The top platform 3 is provided with a connecting pipe 301 that is rotatably connected to the discharge pipe 204 of the feeding assembly. Furthermore, the second motor 8 is fixedly connected to the housing 1 or the feeding bin 2. The output end of the second motor 8 is provided with a pulley 801. A synchronous belt 9 is sleeved on the outside of the connecting pipe 301 and the pulley 801. The second motor 8 drives the connecting pipe 301 to rotate through the pulley 801 and the synchronous belt 9.

[0074] The bottom of the top platform 3 is provided with several shaping rods 303. Making the straw bale 52 into a cuboid or cube shape is more conducive to storage and placement than a cylindrical shape. Therefore, in this embodiment, the bottom of the top platform 3 is fixed with four vertically arranged shaping rods 303, and the four shaping rods 303 form the wrapping film frame of the straw bale 52.

[0075] Depend on Figure 9 As shown, a coaxially arranged annular groove 205 is recessed on the inner wall of the discharge pipe 204. A coaxially arranged retaining ring 302 is fixed to the outside of the connecting pipe 301. The retaining ring 302 is engaged inside the groove 205, and the two are rotatably connected, thereby realizing the rotatable connection between the connecting pipe 301 and the discharge pipe 204, and the two will not separate.

[0076] The support assembly includes a support platform 16 that is slidably disposed directly below the top platform 3. The support platform 16 is used to provide bottom support when straw is added. The bottom of the support platform 16 is provided with a lifting device 17 that is fixedly connected to the inner wall of the housing 1. The lifting device 17 is an electric cylinder or a hydraulic cylinder, and the lifting device 17 drives the support platform 16 to move up and down.

[0077] The secondary wrapping assembly is used to seal the straw bales 52 formed by the primary wrapping assembly by wrapping them again. It wraps the top and bottom surfaces of the straw bales 52 to seal them and increase bottom strength. The secondary wrapping assembly is arranged opposite to the discharge port 101. An inclined guide channel 102 is provided inside the housing 1. The width of the guide channel 102 is greater than the width of the straw bales 52. It is located directly below the secondary wrapping assembly and extends low to the outside of the discharge port 101.

[0078] Both the primary and secondary wrapping assemblies include a wrapping film supply assembly. Figures 15 to 17 As shown, the stretch film supply assembly includes a U-shaped stretch film mounting bracket 18. The two parallel end plates of the stretch film mounting bracket 18 have insertion slots. A detachably connected first insert rod 20 is inserted into the insertion slot, and a stretch film roll 36 is sleeved on the first insert rod 20. A threaded hole is recessed at the end of the first insert rod 20, and a fixing clip 21 is detachably installed via a threaded connection.

[0079] The extrusion plate 19 is rotatably connected to one side of the wrapping film mounting frame 18, and is connected between the extrusion plate 19 and the wrapping film mounting frame 18 through an elastic element 22. The elastic element 22 is a spring top rod or a gas spring support rod, and the maximum stroke of the elastic element 22 is used to limit the maximum angle between the extrusion plate 19 and the wrapping film mounting frame 18.

[0080] The end of the extrusion plate 19 away from the wrapping film mounting frame 18 is slidably provided with a blade 24 and a wrapping film clamping device. The wrapping film flat laying part 3601 pulled out from the wrapping film roll 36 is arranged in close contact with the extrusion plate 19, and the free end of the wrapping film flat laying part 3601 is fixed by the wrapping film clamping device.

[0081] The blade 24 is slidably connected with a blade sliding groove 1901 at the end of the extrusion plate 19, and the blade edge of the blade 24 faces the wrapping film flat laying part 3601. The end of the blade 24 away from the wrapping film flat laying part 3601 is connected with a second electromagnet 25, and the second electromagnet 25 is fixedly connected to the back of the extrusion plate 19.

[0082] The wrapping film clamping device includes two L-shaped plates 26, which are arranged opposite to each other at the two ends of the extrusion plate 19. The L-shaped plates 26 are rotatably connected with the extrusion plate 19, and a torsion spring is arranged at the rotatable connection. Under the pushing force of the torsion spring, one end surface of the L-shaped plate 26 is in close contact with the front end surface of the extrusion plate 19, so as to clamp and fix the end of the wrapping film flat laying part 3601.

[0083] One end surface of the L-shaped plate 26 extends to the back of the extrusion plate 19 and is fixed with a pull rope 27. Two pull ropes 27 are connected with a wire roller 28 in the middle. The wire roller 28 is rotatably connected with the extrusion plate 19, and the back of the extrusion plate 19 is provided with a third electromagnet 31 for controlling the rotation of the wire roller 28. Further, the third electromagnet 31 is fixed with a rack 30, the rack 30 is meshingly connected with a gear 29, and the gear 29 is coaxially fixed with the wire roller 28.

[0084] In order to make the wrapping film smoothly pass from the wrapping film roll 36 to the extrusion plate 19, a guide roller 23 rotatably connected with the wrapping film mounting frame 18 is arranged between the extrusion plate 19 and the wrapping film mounting frame 18. After the wrapping film passes through the guide roller 23, the wrapping film flat laying part 3601 abutting against the extrusion plate 19 is formed.

[0085] The first insertion rod 20 of the wrapping film supply assembly used in cooperation with the primary wrapping film assembly is arranged vertically, which is convenient for wrapping the four vertical surfaces of the straw bag 52.

[0086] The first insertion rod 20 of the wrapping film supply assembly used in cooperation with the secondary wrapping film assembly is arranged horizontally, which is convenient for wrapping the top surface and the bottom surface of the straw bag 52.

[0087] However, if the straw bale 52 is only wrapped around the four sides during the first wrapping, the straw will fall off during the straw bale 52 is transferred from the first wrapping assembly to the second wrapping assembly. Therefore, the bottom of the straw bale 52 needs to be wrapped during the first wrapping.

[0088] To achieve the above functions, the wrapping film mounting rack 18 of the wrapping film supply assembly used in cooperation with the first wrapping assembly is externally provided with a first linear module 32 arranged vertically, and the first linear module 32 is fixedly connected to the inner wall of the housing 1. The sliding part of the first linear module 32 is provided with an upper telescopic device 33 and a lower telescopic device 34. The end of the telescopic rod of the upper telescopic device 33 is rotationally connected to the wrapping film mounting rack 18, and the end of the telescopic rod of the lower telescopic device 34 is rotationally connected to a sliding block 35, and the sliding block 35 is slidingly connected to the wrapping film mounting rack 18.

[0089] During the first wrapping, the second motor 8 drives the top table 3 and the shaping rod 303 to rotate. Under the pushing of the elastic member 22, the ends of the spread extrusion plates 19 are located on the track of the rotation of the shaping rod 303, and the rotating shaping rod 303 touches the extrusion plates 19 and compresses the elastic member 22. The third electromagnet 31 is energized to drive the wire roller 28 to rotate, pull the continuous and disconnected pull rope 27, and make the L-shaped plate 26 rotate to release the locking of the end of the wrapping film flat part 3601. When the shaping rod 303 contacts the wrapping film, the wrapping film is pulled to be wrapped.

[0090] After the four sides of the straw bale 52 are wrapped and formed, the sliding part of the first linear module 32 drives the upper telescopic device 33 and the lower telescopic device 34 to move downward, and the telescopic rods of the two are elongated. The elongation length of the telescopic rod of the lower telescopic device 34 is greater than that of the telescopic rod of the upper telescopic device 33, so that the entire wrapping film supply assembly is arranged obliquely, and the lower half of the wrapping film is located below the shaping rod 303. At this time, the wrapping is continued to form the bottom outline of the straw bale 52.

[0091] After the bottom outline is completed, the wrapping film supply assembly is reset, the third electromagnet 31 is de-energized, the L-shaped plate 26 is reversed under the action of the torsional spring, and the end of the wrapping film flat part 3601 is pressed again. The second electromagnet 25 is energized, and the blade 24 moves forward to cut the wrapping film.

[0092] Then the support table 16 moves upward to push and extrude the bottom outline of the straw bale 52 to make it flat, and the bottom shaping of the straw bale 52 is completed.

[0093] In order to avoid the situation that the shaping rod 303 is not in contact with the wrapping film when the third electromagnet 31 is powered on, causing the wrapping film to slide off and the rotating shaping rod 303 to fail to drive the wrapping film. In the initial state, one of the shaping rods 303 is in abutment with the wrapping film flat portion 3601 on the pressing plate 19, and the position of the above-mentioned shaping rod 303 is located at the same position each time the top table 3 stops rotating.

[0094] In order to achieve this purpose, the top table 3 is provided with two vertically arranged positioning rods 304, and the two positioning rods 304 are coaxially arranged with the two diagonally arranged shaping rods 303.

[0095] The top table 3 is provided with two rotating cylinders 10 fixedly connected to the outer wall of the feeding bin 2, and the rotating cylinder 10 adopts the prior art and can adopt an electric cylinder or a hydraulic cylinder. Each time the rotating cylinder 10 is started, the rotating angle of the output shaft of the rotating cylinder 10 is 90° to 180°.

[0096] The output shaft of the rotating cylinder 10 drives the clamping plate 11 to rotate, and the rotating angle of the clamping plate 11 is 90° to 180°. The rotating directions of the two clamping plates 11 are opposite, and when the two clamping plates 11 rotate to abut against the positioning rod 304 above the top table 3, they are located on the same side of the positioning rod 304. In this way, through the limitation of the two clamping plates 11, the top table 3 cannot be rotated forward or reversed, and is clamped in one position. When the top table 3 needs to be rotated, the rotating cylinder 10 drives the clamping plate 11 to rotate in the opposite direction, and moves out of the rotating path of the positioning rod 304, so that interference does not occur.

[0097] After the outer wall of the straw bag 52 is pre-formed by the first film wrapping assembly, the rotating drum 206 is rotated to the direction in which the storage tank 207 filled with straw is in through connection with the discharge pipe 204, and the straw is filled into the pre-formed straw bag 52.

[0098] After the filling is completed, the straw bag 52 needs to be taken out and separated from the shaping rod 303. In order to facilitate separation, the higher the smoothness of the surface of the shaping rod 303, the better. However, if the smoothness of the surface of the shaping rod 303 is high, it is not easy to drive the end of the wrapping film to rotate during film wrapping.

[0099] Therefore, in the embodiment, the vertical hole 3031 is provided in the shaping rod 303 in contact with the wrapping film flat portion 3601 in the initial state, and the control rod 4 is slidably arranged in the vertical hole 3031. Figure 12 and Figure 13 As shown in the initial state, the vertical hole 3031 is provided in the shaping rod 303 in contact with the wrapping film flat portion 3601, and the control rod 4 is slidably arranged in the vertical hole 3031. The side wall of the control rod 4 is recessed with an inclined groove 401 in the direction facing the wrapping film flat portion 3601.

[0100] A vertical hole 3031 is connected to several horizontal holes 3032. The openings of the horizontal holes 3032 on the surface of the shaping rod 303 face the film spreading section 3601. The inner diameter of the opening of the horizontal hole 3032 is smaller than its inner diameter. A scraper 5 is slidably provided inside the horizontal hole 3032. A slide rod 501 and a spring seat 502 are fixed sequentially at one end of the scraper 5 facing the control rod 4. A first spring 6 is sleeved on the slide rod 501. The two ends of the first spring 6 abut against the spring seat 502 and the inner end face of the opening of the horizontal hole 3032. The spring seat 502 abuts against the inclined groove 401.

[0101] The top end of the control lever 4 extends to the top surface of the top platform 3 and is fixedly connected to the telescopic part of the first electromagnet 7. The first electromagnet 7 is fixedly connected to the top platform 3. Since the electromagnet consumes little electricity, a power supply assembly using a storage battery and a control switch with remote transmission function are provided on the top platform 3. The control switch is connected in series with the first electromagnet 7 and the power supply assembly.

[0102] When the electromagnet 7 is energized, the control lever 4 moves down, overcoming the thrust of the first spring 6 to push the spring seat 502 outward. The scraper 5 abuts against the stretch film spreading section 3601, and can rotate the stretch film together with the shaping rod 303 by means of a hook. After the top platform 3 rotates 2-3 times, the first electromagnet 7 is de-energized, and the scraper 5 retracts into the horizontal hole 3032.

[0103] To assist the straw bale 52 in moving downwards and detaching from the shaping rod 303, by Figure 10 as well as Figure 11 As shown, a pressure plate 12 is provided at the bottom of the top platform 3. The pressure plate 12 has a through hole in the middle, and the inner diameter of the through hole is larger than the inner diameter of the connecting pipe 301. The two ends of the pressure plate 12 extend to the outside of the top platform 3.

[0104] A vertical rod 1201 is fixed to the top of the pressure plate 12. The upper end of the vertical rod 1201 passes through the hole of the top platform 3 and is fixed with a retaining ring assembly 1202. A second spring 13 is sleeved on the vertical rod 1201 located above the top platform 3. Under the push of the second spring 13, the pressure plate 12 moves upward and abuts against the bottom surface of the top platform 3.

[0105] A frame 14 is provided above the top platform 3. A ring groove 1401 is provided in the middle of the frame 14, and a retaining ring assembly 1202 is slidably disposed in the ring groove 1401. A first telescopic device 15 is provided at each end of the frame 14. The outer wall of the first telescopic device 15 is fixedly connected to the shell 1 or the feed hopper 2, and the telescopic part of the first telescopic device 15 is fixedly connected to the frame 14.

[0106] The first telescopic device 15 controls the pressure plate 12 to move downward, pressing down the straw bale 52 and causing it to detach from the shaping rod 303.

[0107] The transfer assembly, including a moving component and a clamping component, is used to transfer the straw bale 52 formed by the wrapping from the primary wrapping assembly to the secondary wrapping assembly.

[0108] Depend on Figure 18 As shown, the moving component of the transfer assembly includes two parallel, spaced-apart second linear modules 37. The movable parts of the two second linear modules 37 are jointly fixed to a vertically arranged third linear module 38. The movable part of the third linear module 38 is fixedly connected to the clamping component. The first linear module 32, the second linear module 37, and the third linear module 38 are all electric linear modules, which is existing technology.

[0109] The clamping assembly includes a snap-fit ​​bracket 39, inside which a screw 40 is rotatably mounted. The screw 40 has two threads with opposite directions of rotation. A third motor 41 is fixed on the snap-fit ​​bracket 39, and the third motor 41 drives the screw 40 to rotate.

[0110] The snap-fit ​​bracket 39 has a first support plate 42 and a second support plate 43 that are slidably provided inside. The first support plate 42 and the second support plate 43 are respectively threadedly connected to the two threaded parts of the screw 40.

[0111] The first support plate 42 is provided with a first clamp 44, and the second support plate 43 is provided with a second clamp 45.

[0112] The first clamp 44 is rotatably connected to the first support plate 42 via the first rotating rod 4401, and the second clamp 45 is rotatably connected to the second support plate 43 via the second rotating rod 4501.

[0113] The second rotating rod 4501 of the second clamp 45 is provided with a hexagonal head 4502 at its end.

[0114] The secondary wrapping assembly includes a wrapping rotation control motor 49. The output shaft of the wrapping rotation control motor 49 is provided with an internal hexagonal sleeve 4901. The internal hexagonal sleeve 4901 is connected to the hexagonal head 4502. When the transfer assembly transfers the straw bale 52 to the position of the secondary wrapping assembly, the hexagonal head 4502 is inserted into the internal hexagonal sleeve 4901, and the straw bale 52 abuts against the wrapping film laying part 3601 at the end of the extrusion plate 19 of the wrapping film supply assembly.

[0115] The second rotating rod 4501 has a spring cavity 4503 inside. The circumferential surface of the second rotating rod 4501 has a locking rod groove 4504 that is connected to the spring cavity 4503. The spring cavity 4503 has a third spring 48 inside. The locking rod 47 is slidably provided inside the spring cavity 4503. The end of the locking rod 47 extends to the outside of the hexagonal head 4502. The sliding rod is slidably provided inside the locking rod groove 4504.

[0116] One end of the slide rod is fixedly connected with the end of the locking rod 47 inside the spring cavity 4503, and the other end is fixedly connected with the second insertion rod 4701, which is arranged in parallel with the locking rod 47.

[0117] The second support plate 43 comprises a disc 4301 coaxially arranged with the second rotating rod 4501, and the disc 4301 is provided with an insertion hole 4302, and the second insertion rod 4701 is inserted into the insertion hole 4302.

[0118] The second rotating rod 4501 is fixedly connected with three connecting plates 46 arranged perpendicularly to each other, and the end of the connecting plate 46 is provided with clamping plates 4601 arranged perpendicularly to each other. The part of the clamping plate 4601 in contact with the flat-lying part 3601 of the wrapping film is provided with a plurality of arc-shaped protrusions 4602, so that when the clamping plate 4601 rotates and abuts against the flat-lying part 3601 of the wrapping film, the flat-lying part 3601 can be taken away by the protrusions 4602.

[0119] When the second insertion rod 4701 is inserted into the insertion hole 4302, two connecting plates 46 are arranged in parallel, and the other connecting plate 46 is arranged vertically upward. Through the insertion of the second insertion rod 4701 into the insertion hole 4302, the positioning of the connecting plate 46 and the clamping plate 4601 is realized, and it can also be ensured that the hexagonal head 4502 does not rotate during the movement of the clamping assembly, so that the hexagonal head 4502 can be smoothly inserted into the internal hexagonal sleeve 4901 next time.

[0120] The length of the second insertion rod 4701 inserted into the insertion hole 4302 is less than the length of the locking rod 47 outside the hexagonal head 4502.

[0121] In use, after the film is wrapped once, before the support table 16 is moved upward, the clamping assembly is moved to a position between the top table 3 and the support table 16, and then moves upward together with the support table 16. The first clamping device 44 and the second clamping device 45 are respectively located on both sides of the pre-formed straw bag 52, and the straw bag 52 is clamped in the middle.

[0122] After the straw bag 52 is filled with straw, the first clamping device 44 and the second clamping device 45 are moved towards each other, and the parts of the two clamping devices in contact with the straw bag 52 are wrapped with rubber sleeves. The two clamping devices clamp the straw bag 52, and the clamping plates 4601 respectively abut against the two vertical surfaces and the top surface of the straw bag 52.

[0123] Then the clamping assembly moves downward, and after the straw bag 52 is completely separated from the shaping rod 303, it is driven by the second linear module 37 to the position of the secondary film wrapping assembly. At this time, the flat-lying part 3601 of the wrapping film at the end of the extrusion plate of the secondary film wrapping assembly abuts against the clamping plate 4601 below.

[0124] After the hexagonal head 4502 is inserted into the interior of the internal hexagonal sleeve 4901, the locking rod 47 is retracted, the second insertion rod 4701 is moved to the outside of the insertion hole 4302, the film winding rotation control motor 49 drives the second clamping device 45 to rotate by using the servo motor, and then drives the straw bag 52 to rotate. When the straw bag 52 rotates, the protrusion 4602 abuts against the winding film of the winding film flat part 3601, and pulls the winding film. The rotation direction ensures that the sidewall of the straw bag 52 first contacts the winding film, and then the top contacts the winding film on the extrusion plate 19. At this time, under the action of the extrusion plate 19, the straw in the rotating straw bag 52 will not leak out from the top.

[0125] The second telescopic device 51 is fixed on the inner wall of the shell 1, and the telescopic part of the second telescopic device 51 is connected with the horizontally arranged push plate 50, which is correspondingly arranged with the straw bag 52 corresponding to the secondary film winding assembly.

[0126] After the straw bag 52 is completed twice winding film, the distance between the first clamping device 44 and the second clamping device 45 is enlarged, and since the clamping plate 4601 is wound inside, at this time the straw bag 52 cannot be automatically detached. At this time, the push plate 50 is lengthened, the straw bag 52 is pushed by the push plate 50, the clamping plate 4601 is pulled out, and the straw bag 52 falls onto the material guiding channel 102 and then slides out of the discharge port 101.

[0127] The stem and ear combined type corn harvester straw automatic packaging device is arranged in the straw bin or hopper of the corn harvester, and the telescopic device contained in the interior thereof adopts an electric cylinder or a hydraulic cylinder. The electric control and hydraulic parts contained in the interior of the stem and ear combined type corn harvester straw automatic packaging device are connected with the electric control assembly and the hydraulic control station of the corn harvester itself.

[0128] The straw bag 52 discharged through the discharge port 101 is a cube or a cuboid, which can be scattered in the corn field and wait for subsequent collection, or can be directly placed in the straw bin or hopper of the corn harvester by artificial means.

[0129] The above describes the embodiments of the application in detail in combination with the drawings, but the application is not limited to the above embodiments, and various changes can be made within the knowledge range of ordinary skilled in the art without departing from the purpose of the application.
