[0002] In the prior art, for example, Chinese utility model patent publication number CN207476266U discloses a fixed-type pressurized hay baler. This device uses a push plate and a pressure plate to pressurize and shape hay bales in multiple steps, significantly improving the density of the hay bales and preventing loose hay bales that are difficult to transport and store. A weight sensor ensures a constant weight for easy measurement. However, this technical solution still has the following drawbacks: 1. Because the device is fixed, the hay must be manually transported to the baler for manual loading, which is labor-intensive. 2.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0027] like Figure 1 、 3As shown, an embodiment provides a forage harvesting and baling device, including a vehicle body 1 and a harvesting mechanism 2, a sorting mechanism 3, and a baling mechanism 4, which are sequentially arranged on the vehicle body 1 from left to right. The sorting mechanism 3 includes a protective cover 31, a sorting motor 32, a clamping module 33, a forage conveyor belt 34, a limit baffle 35, and a vibration module 36. The protective cover 31 is fixed to the vehicle body 1. The sorting motor 32 is fixed to the protective cover 31. The output end of the sorting motor 32 is connected to the clamping module 33. The forage conveyor belts 34 are symmetrically arranged on both sides of the clamping module 33, and the forage conveyor belts 34 are arranged at an angle. A limit baffle 35 is provided on the lower side of the forage conveyor belt 34, and a vibration module 36 is also provided on the inner side of the forage conveyor belt 34. In this embodiment, the vehicle body 1 is a common component on the market and can be moved, which facilitates the movement of the device to the working area and realizes continuous harvesting operations. The harvesting mechanism 2 is provided for harvesting forage and transporting the forage to the sorting mechanism 3 for sorting. The sorting mechanism 3 is used to separate the longer grass from the shorter grass, and transport them to the baling mechanism 4 for baling, thereby preventing the uneven length of the grass from causing the baled grass to become loose and improving the baling quality. The baling mechanism 4 is used to compact the grass into a square haystack, thereby completing the baling of the grass. Among them, the protective cover 31 is installed on the vehicle body 1, which can protect the internal components and make the device more beautiful; the power shaft of the sorting motor 32 is arranged horizontally, and is used to drive the clamping module 33 to rotate, and when the length of the grass exceeds a certain value (that is, exceeds the width of the grass conveyor belt 34), the clamping module 33 can clamp the top of the grass, and then the clamping module 33 can transfer the longer grass from one grass conveyor belt 34 to another grass conveyor belt 34 when rotating, so as to achieve the purpose of sorting; the grass conveyor belt 34 is fixedly installed on the inner wall of the protective cover 31, and is arranged in a suspended manner. 34 is equipped with a motor that drives the grass conveyor belt 34 to rotate, thereby achieving the automatic feeding function. Since the grass conveyor belt 34 is arranged at an angle, the grass on it will automatically slide down under the action of gravity. At the same time, the vibration module 36 provided in conjunction with it can vibrate and disperse the grass on the grass conveyor belt 34. When the roots of the grass abut against the limit baffle 35, its ends automatically align, so that the grass on the grass conveyor belt 34 is arranged neatly to ensure the quality of baling. The limit baffle 35 is fixedly mounted on the inner wall of the protective cover 31, and the contact surface between the limit baffle 35 and the grass is coated with a smooth protective film to reduce friction. In addition, a main controller is also provided on the vehicle body 1. The main controller can be a single-chip microcomputer, a PLC, or other digital processor. The harvesting mechanism 2, the sorting mechanism 3, and the baling mechanism 4 are all electrically connected to the main controller, so that the various components can be controlled to work together. The components used in this device are all commercially available.

[0028] Specifically, such as Figure 3 、5 As shown, the clamping module 33 includes a mounting base 331, a clamping motor 332, a first screw 333, a first slider 334, and a clamping rod 335. The mounting base 331 is fixed to the power shaft of the sorting motor 32. The clamping motor 332 is fixed to the mounting base 331. The first screw 333 is connected to the power shaft of the clamping motor 332. The first screw 333 is provided with two threaded sections with opposite spiral directions. Each threaded section is threadedly connected to the first slider 334. The first slider 334 is provided with a clamping rod 335. In this embodiment, the mounting base 331 is a U-shaped plate structure, and the two first sliders 334 are both located on the inner side of the U-shaped plate. The clamping motor 332 is configured to drive the first screw 333 to rotate, thereby causing the two first sliders 334 to move closer to or farther away from each other. The two clamping rods 335 are arranged horizontally and in parallel, and when the first slider 334 moves, the clamping rods 335 can be driven to move synchronously. For example, when the two clamping rods 335 are close to each other, they can clamp the top of a long grass, and the grass conveyor belt 34 should be in a stopped state. Conversely, when the two clamping rods 335 are moved away from each other, the top of the grass is released, and the grass conveyor belt 34 can drive the grass to move, thereby achieving feeding. The clamping rods 335 are preferably straight rods, but can also have other shapes.

[0029] Specifically, such as Figure 5 As shown, a rubber pad 336 is provided on the clamping rod 335. In this embodiment, the rubber pad 336 is located on the side where the two clamping rods 335 are close to each other, and the rubber pad 336 has a certain elasticity and can produce adaptive deformation to ensure the clamping effect of the clamping rod 335 on the forage.

[0030] Specifically, such as Figure 4 As shown, the vibration module 36 includes a vibration motor 361 and a vibration plate 362. The vibration motor 361 is fixed to the protective cover 31. The output end of the vibration motor 361 is connected to the vibration plate 362, and the vibration plate 362 is in contact with the inner wall of the grass conveyor belt 34. In this embodiment, the vibration motor 361 is a common component on the market, and the vibration motor 361 is configured to drive the vibration plate 362 to vibrate. The grass conveyor belt 34 is an annular structure, and the vibration plate 362 is a flat plate. The top surface of the vibration plate 362 is in contact with the inner top wall of the grass conveyor belt 34. As a result, when the vibration plate 362 vibrates, it can synchronously vibrate the grass conveyor belt 34 and the grass thereon. Then, under the action of gravity, one end of the root of the grass contacts the surface of the limit baffle 35, thereby achieving one-end alignment.

[0031] Specifically, such as Figure 1 、 3As shown in Figures 4 and 6, the harvesting mechanism 2 includes a harvesting chamber 201, a harvesting motor 202, a roller 203, a rotating plate 204, a cutting tool 205, a transfer platform 206, a first rotating shaft 207, a push plate 208, a transmission rod 209, a triangular transmission belt 210 and a transmission assembly. The harvesting chamber 201 is fixed on the vehicle body 1, and a harvesting motor 202 is provided on the inner wall of the harvesting chamber 201. The output end of the harvesting motor 202 is connected to a roller 203. More than two rotating plates 204 are evenly arranged on the roller 203. The rotating plates 204 A serrated cutting blade 205 is provided at the front end. A transfer platform 206 is horizontally disposed above the roller 203 and is rotatably connected to the harvesting bin 201 via a first rotating shaft 207. A push plate 208 is disposed above the transfer platform 206. A triangular transmission belt 210 is fixed to the inner wall of the harvesting bin 201, and one end of the push plate 208 is connected to the triangular transmission belt 210 via a transmission rod 209. Both the first rotating shaft 207 and the triangular transmission belt 210 are connected to the power shaft of the harvesting motor 202 via a transmission assembly. In this embodiment, the harvesting bin 201 has a cavity therein, and during installation, the bottom end surface of the harvesting bin 201 is as close to the ground as possible to ensure that the forage is harvested effectively. One end of the forage conveyor belt 34 extends into the harvesting bin 201, and the edge of the forage conveyor belt 34 is close to the transfer platform 206, capable of receiving the forage dropped from the transfer platform 206. The harvesting motor 202 is a common component on the market, used to drive the roller 203. The roller 203 is arranged horizontally inside the harvesting chamber 201. One end of the roller 203 is connected to the power shaft of the harvesting motor 202, and the other end is rotatably connected to the inner wall of the harvesting chamber 201. The rotating plate 204 is a plate-like structure, with four rotating plates 204 evenly arranged on the side wall of the roller 203. Cutting knives 205 are installed on the end of the rotating plate 204 away from the roller 203. Every 90° rotation of the roller 203 causes one of the cutting knives 205 to rotate forward, allowing the roots of the grass to be lodged in the serrated grooves of the cutting knives 205. As the vehicle body 1 continuously moves forward during operation, it pushes the cutting knives 205 forward synchronously, thereby severing the roots of the grass under the thrust. Since the grass is stuck in the serrated grooves, the rotation of the roller 203 can simultaneously lift the grass. Transfer platform 206 is arranged horizontally, and when rotating plate 204 is rotated to the top (i.e., vertically), the edge of cutting blade 205 aligns with the edge of transfer platform 206 without interfering with each other, thereby transferring grass from cutting blade 205 to transfer platform 206. First rotating shaft 207 is arranged vertically, and cutting blade 205 does not interfere with first rotating shaft 207 during rotation. Push plate 208 is arranged horizontally, and its bottom end surface can be aligned with the top surface of transfer platform 206.The triangular transmission belt 210 is a triangular structure and is arranged vertically. When the triangular transmission belt 210 rotates, it can drive the push plate 208 to slide from one end to the other on the transfer platform 206, thereby pushing the forage on the transfer platform 206 onto one of the forage conveyor belts 34. If the triangular transmission belt 210 continues to rotate, the push plate 208 will disengage from the transfer platform 206 and return to its initial position. At this time, the triangular transmission belt 210 has completed one rotation. The transmission assembly configured enables the harvesting motor 202 to control the roller 203, the first rotating shaft 207, and the triangular transmission belt 210 to work in coordination.

[0032] Specifically, such as Figure 3 、 4As shown in Figures 6 and 7, the transmission assembly includes a first driving gear 211, a chain 212, a first driven gear 213, a transmission shaft 214, a first bevel gear 215, and a second bevel gear 216. The first driving gear 211 is fixedly mounted on the power shaft of the harvesting motor 202. Two transmission shafts 214 are rotatably connected to the inner side wall of the harvesting bin 201. The transmission shafts 214 are fixedly mounted with the first driven gear 213 and the first bevel gear 215. The first driving gear 211 and the first driven gear 213 are connected by the chain 212. The first rotating shaft 207 and the rotating shaft of the triangular transmission belt 210 are both provided with a second bevel gear 216 that meshes with the first bevel gear 215. In this embodiment, the first driving gear 211 and the first driven gear 213 are both spur gears, and the chain 212 is used for transmission, so that the roller 203 and the two transmission shafts 214 can rotate synchronously. The two transmission shafts 214 are both arranged horizontally, and the central axes of the two transmission shafts 214 are both arranged parallel to the central axis of the roller 203 . The two second bevel gears 216 are both complete gears, the first bevel gear 215 meshing with the second bevel gear 216 on the first rotating shaft 207 is an incomplete gear, and the other first bevel gear 215 is a complete gear, and the gear ratios between the first driving gear 211 and the first driven gear 213, and between the first bevel gear 215 and the second bevel gear 216 are calculated to ensure that when the roller 203 rotates 1 / 4 circle, the transmission shaft 214 connected to the incomplete gear can just rotate one circle, thereby causing the incomplete gear to also rotate one circle. For example, when the incomplete gear rotates to mesh with the second bevel gear 216, it can drive the first rotating shaft 207 and the transfer platform 206 to rotate 90°, and when the incomplete gear rotates to disengage from the second bevel gear 216, the first rotating shaft 207 and the transfer platform 206 will stop. When the transfer platform 206 is in a stationary state, forage can be placed on the transfer platform 206 and the forage on the transfer platform 206 can be pushed off. At the same time, when the roller 203 rotates 1 / 4 of a turn, it can drive the triangular transmission belt 210 to rotate exactly one turn. During this process, the push plate 208 pushes the grass off the transfer platform 206 and returns to its original position. In addition, it should be noted that the process of the cutting tool 205 placing the grass on the transfer platform 206 and the process of the push plate 208 pushing the grass off the transfer platform 206 are both completed when the transfer platform 206 is in a stationary state.

[0033] Specifically, such as Figure 2 、 3As shown in Figures 5 and 6, the baling mechanism 4 includes a rotary drive unit 41, a rotary block 42, a guide rail 43, a baling bin 44, a left-right displacement motor 45, a rotating gear 46, and a lifting unit 47. The rotary drive unit 41 is fixed to the vehicle body 1, with the output end of the rotary drive unit 41 connected to the rotary block 42. The guide rail 43 is fixed to the bottom of the baling bin 44 and slidably connected to the top of the rotary block 42. The left-right displacement motor 45 is fixed to the rotary block 42. The power shaft of the left-right displacement motor 45 is connected to the rotating gear 46, which meshes with the tooth groove at the bottom of the baling bin 44. The baling bin 44 is provided with a lifting unit 47, which includes a lifting plate 471 that is slidably connected to the inner wall of the baling bin 44. In this embodiment, the rotary drive unit 41 is used to drive the rotary block 42 to rotate. Two guide rails 43 are provided, each with an inverted T-shaped cross-section. A T-slot is provided at the top of the rotating block 42, which slidably engages with the guide rails 43. This allows the baling chamber 44 to slide left and right while preventing it from separating from the rotating block 42. A groove is also provided at the top of the rotating block 42, within which a left-right displacement motor 45 is located. This left-right displacement motor 45 drives a rotating gear 46, which in turn drives the baling chamber 44 to slide back and forth, adjusting its position and ensuring that the hay is evenly distributed within it as the hay is moved. The lifting plate 471 is a flat plate structure, and a lifting portion 47 is provided to drive the lifting plate 471 up and down, shortening the distance between the top of the hay pile on the lifting plate 471 and the hay conveyor belt 34. This ensures that the hay does not become scattered during its fall, thus improving the quality of baling.

[0034] Specifically, such as Figure 1 、 2 As shown in Figures 5 and 6, the rotary drive unit 41 includes a rotary motor 411, a second driving gear 412, a second rotating shaft 413, and a second driven gear 414. The rotary motor 411 is fixed to the vehicle body 1. The second driving gear 412 is connected to the power shaft of the rotary motor 411. The second rotating shaft 413 is vertically connected to the vehicle body 1. The second driven gear 414 and the rotating block 42 are fixed to the second rotating shaft 413, and the second driving gear 412 and the second driven gear 414 are meshed. In this embodiment, the power shaft of the rotary motor 411 is arranged vertically upward and can drive the second driving gear 412 to rotate. The second driving gear 412 and the second driven gear 414 are both fully geared. Since the second driving gear 412 is meshed with the second driven gear 414, the rotating motor 411 can drive the second rotating shaft 413 to rotate. The rotation of the second rotating shaft 413 will drive the rotating block 42 to rotate synchronously to adjust the head and tail directions of the baling bin 44, thereby realizing alternating laying of forage from the head and tail ends of the baling bin 44. With this laying method, the thickness of the hay stack on the lifting plate 471 will be more uniform at various locations, so that the baled hay stack is not easy to loosen.

[0035] Specifically, such as Figure 5 、 7 As shown, the lifting unit 47 also includes a lifting motor 472, a second screw rod 473, and a flange 474. The lifting motor 472 is fixed to the outer wall of the bundling chamber 44. The output end of the lifting motor 472 is connected to the second screw rod 473. Slide grooves 475 are vertically provided on both sides of the bundling chamber 44. Lugs 474 are provided on both sides of the lifting plate 471 and are slidably connected to the slide grooves 475. The second screw rod 473 is threadedly connected to one of the lugs 474. In this embodiment, the lifting motor 472 is fixed to one side of the bundling chamber 44, and the power shaft of the lifting motor 472 is arranged vertically upward. The second screw rod 473 is also arranged vertically. The lifting motor 472 can drive the second screw rod 473 to rotate, thereby causing the lifting plate 471 to move up and down within the bundling chamber 44. The flange 474 is a square block structure and can slide up and down within the slide groove 475.

[0036] Specifically, such as Figure 3 As shown, the baling mechanism 4 also includes a squeezing module 48, which includes a hydraulic push rod 481 and a squeezing plate 482. The hydraulic push rod 481 is fixed to the protective cover 31, and the output end of the hydraulic push rod 481 is connected to the squeezing plate 482. The lifting plate 471 is evenly distributed with filter holes. In this embodiment, the squeezing module 48 is used to squeeze the hay in the baling bin 44 into a pile and squeeze out moisture from the hay, preventing moisture and mold, and facilitating subsequent storage. The hydraulic push rod 481 is arranged vertically, and the squeezing plate 482 is also a flat plate structure. The squeezing plate 482 is aligned with the baling bin 44. The hydraulic push rod 481 is configured to drive the squeezing plate 482 downward to squeeze the hay in the baling bin 44 into a pile. The squeezed moisture flows through the filter holes at the bottom to the bottom of the baling bin 44, and then is discharged to the ground through a drainage hole at the bottom of the baling bin 44. After the grass is squeezed into a stack, the lifting plate 471 will push the grass stack out of the baling bin 44, and then control the rotating block 42 to rotate. Under the action of centrifugal force, the grass stack can be thrown to the side of the vehicle body 1. Alternatively, a cylinder can be provided on the protective cover 31 to push the grass stack down.

[0037] Working principle: When in use, the driver enters the cab of the vehicle body 1, controls the movement of the vehicle body 1 and controls the coordinated operation of various components. When the vehicle body 1 is close to the grass, the harvesting motor 202 is started, and the harvesting motor 202 drives the roller 203 and the first driving gear 211 to rotate. When the roller 203 rotates, it will drive the rotating plate 204 and the cutting tool 205 to rotate synchronously. When one of the cutting tools 205 rotates 90° to face the front, the vehicle body 1 continues to move forward, which will cause the roots of the grass to be stuck in the serrated groove of the cutting tool 205, and the roots of the grass will be cut off under the action of the thrust of the vehicle body 1. At this time, the roller 203 continues to rotate, and the cutting tool 205 will lift the grass. When the cutting tool 205 moves to the top, the grass will fall exactly on the transfer platform 206 and... The roots of the grass are separated from the sawtooth groove. At the same time, the rotation of the first driving gear 211 will drive the two transmission shafts 214 to rotate through the chain 212. The rotation of the transmission shaft 214 will drive the first bevel gear 215 connected thereto to rotate. Since the first bevel gear 215 is engaged with the second bevel gear 216, and the first bevel gear 215 that drives the first rotating shaft 207 to rotate is an incomplete gear, the transfer platform 206 can rotate 90° and stop after the grass is placed. At this time, the transmission shaft 214 drives the triangular transmission belt 210 to rotate, and the triangular transmission belt 210 will drive the push plate 208 to move and push the grass on the transfer platform 206 down to the grass conveyor belt 34. After the grass has completely fallen onto the grass conveyor belt 34, the grass conveyor belt 34 starts to move the grass toward the rear of the vehicle. Simultaneously, the vibration motor 361 drives the vibration plate 362 to vibrate, causing the grass conveyor belt 34 and the grass thereon to vibrate synchronously. Combined with the gravity of the grass, the grass is neatly arranged on the grass conveyor belt 34. After the grass conveyor belt 34 has conveyed the grass to the rear section, it stops. The clamping motor 332 then drives the first screw rod 333 to rotate. This rotation of the first screw rod 333 drives the two first sliders 334 toward each other, causing the two clamping rods 335 to clamp the top of the longer grass. At this point, the sorting motor 32 drives the mounting base 331 to rotate, causing the clamping rods 335 to throw the longer grass onto the other grass conveyor belt 34, thereby completing the grass sorting operation.When the sorting is completed, the grass conveyor belt 34 continues to drive the grass to move and send the grass to the lifting plate 471 in the baling bin 44. At the same time, the left and right displacement motors 45 drive the baling bin 44 to move to the right at a constant speed to ensure that a layer of grass is evenly laid on the lifting plate 471. When one side is laid, the rotating motor 411 drives the second driving gear 412 to rotate, and the second driving gear 412 rotates to drive the second driven gear 414 to rotate. The second driven gear 414 rotates to drive the second rotating shaft 413 to rotate, and the second rotating shaft 413 rotates to drive the rotating block 42 to rotate 180°, so that the front and rear sides of the baling bin 44 are swapped and moved again to the bottom of the grass conveyor belt 34. At this time, the left and right displacement motors 45 drive the baling bin 44 to move again, so that a layer of grass can be staggered on the lifting plate 471. By repeating the above steps, a grass pile with uniform thickness can be formed in the baling bin 44. When the hay pile is formed, the hydraulic push rod 481 drives the squeezing plate 482 to move downward to squeeze the hay into a pile and squeeze out the moisture in the hay. Then the lifting motor 472 drives the lifting plate 471 to rise, pushing the hay pile out of the baling bin 44. Then the rotating block 42 rotates, and under the action of the centrifugal force of the rotating block 42, the hay pile will be thrown down to the side of the vehicle body 1, completing the harvesting and baling operation.
