Description

A high-efficiency sheepgrass harvesting device Technical Field

[0001] This invention relates to the field of animal husbandry technology, and in particular to a high-efficiency sheepgrass harvesting device. Background Technology

[0002] Animal husbandry refers to the production sector that raises livestock and poultry through grazing, penning, or a combination of both to obtain animal products or draft animals. Sheepgrass is mainly used for cutting grass or grazing. Rich in nutrients, it is a key forage for livestock to fatten up in summer and autumn, a major forage resource on the Inner Mongolian grasslands, and an important source of hay for autumn harvest. As livestock feed, sheepgrass is typically harvested using harvesting equipment.

[0003] Currently, when using harvesting devices to harvest sheep grass, excessively long sheep grass is prone to getting tangled in the blades or transmission mechanism during harvesting, which can easily cause the harvesting device to malfunction. Moreover, the harvested sheep grass is easily tangled together or stuck to the transmission mechanism and then thrown off, resulting in waste of sheep grass and low harvesting efficiency.

The scraper frame is provided with a plurality of scraping strips. A torsion spring is connected between the scraper frame and the support rod.

[0013] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses a motor to drive the transmission column to rotate, which causes the wheels to rotate, thereby driving the vehicle body and fork blocks to move. The fork blocks will separate the sheep grass on the ground into bundles to prevent the sheep grass from tangling together. The rotation of the transmission column will drive the rotating column to rotate, which will drive several cutting blades to swing back and forth. The back and forth swinging of the cutting blades will continuously open and close with the fixed blades to cut the sheep grass between the fork blocks, thereby cutting the sheep grass for collection. At the same time, the rotation of the reel will roll up the cut sheep grass and roll it onto the conveyor belt. The rotation of the conveyor belt will transport the cut sheep grass into the vehicle body for collection, thereby completing the harvesting of sheep grass.

[0014] 2. This invention uses the intermittent rotation of the conveyor belt to drive the cutting gear to rotate. The rotation of the cutting gear crushes the hay on the conveyor belt, cutting it into small pieces to prevent the hay from becoming too long and tangled together. At the same time, the rotation of the cutting gear drives the spiral wheel to rotate intermittently, which disperses the hay piled up on the conveyor belt, allowing the hay to be spread more evenly on the conveyor belt. This enables the cutting gear to cut the hay into smaller pieces more effectively, thus more effectively preventing the hay from tangling with the conveyor belt and rotating column, avoiding device malfunctions, and thus enabling more efficient harvesting of hay.

[0015] 3. This invention uses a transmission column to drive a cleaning brush and several protrusions to rotate together. The rotating cleaning brush removes the hay adhering to the conveyor belt, causing the hay to fall completely into the vehicle body. The rotating protrusions are continuously squeezed by the squeezing column, causing the cleaning brush to move back and forth. This back-and-forth movement of the cleaning brush can more thoroughly remove the hay adhering to the conveyor belt, allowing the hay to fall more completely into the vehicle body. It also prevents the conveyor belt from throwing the adhering hay out of the vehicle body, thus avoiding waste of hay and achieving efficient harvesting of hay. Attached Figure Description

Detailed Implementation

[0024] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the prior art, and will not be described in detail here.

[0025] Example 1: A high-efficiency sheepgrass harvesting device, as shown in Figures 1-5, includes a vehicle body 1, fork blocks 2, a moving mechanism, a harvesting mechanism, and a cutting mechanism. The fork blocks 2 are bolted to one side of the lower part of the vehicle body 1. The moving mechanism is located on the vehicle body 1. The harvesting mechanism is located on the fork blocks 2. The cutting mechanism is located on the fork blocks 2.

[0026] The moving mechanism includes a rotating shaft 32, a wheel 33, a transmission column 34, a drive shaft 341, a transmission belt 35, a support seat 36, a drive gear 361, and a motor 37. Two rotating shafts 32 are rotatably connected to the bottom of the vehicle body 1. Both rotating shafts 32 are horizontally positioned, and wheels 33 are bolted to both ends of each rotating shaft 32. The transmission column 34 is rotatably connected to the upper part of the vehicle body 1 and is horizontally positioned. The drive shaft 341 is rotatably connected to one side of the vehicle body 1. A transmission belt 35 is wound between the drive shaft 341 and the rotating shaft 32 near the fork block 2. The support seat 36 is bolted to the side of the vehicle body 1 near the transmission belt 35. A drive gear 361 is connected to the transmission column 34 via a key, and another drive gear 361 is connected to the drive shaft 341 via a key. The two drive gears 361 mesh. The motor 37 is bolted to the top of the support seat 36, and the output shaft of the motor 37 is fixedly connected to one end of the transmission column 34.

[0027] The harvesting mechanism includes a support frame 41, a rotating column 42, a conveyor belt 43, a support column 44, a drive shaft 45, a take-up shaft 46, a rotating belt 47, and a cutting gear 49. Two support frames 41 are bolted to the fork block 2. The two support frames 41 are symmetrically arranged, and a rotating column 42 is rotatably connected between the two support frames 41. The rotating column 42 is horizontally arranged. A conveyor belt 43 is wound between the drive column 34 and the rotating column 42. Two support columns 44 are bolted to the fork block 2. The support columns 44 are symmetrically arranged, and a drive shaft 45 is rotatably connected between the two support columns 44. The drive shaft 45 is horizontally arranged, and the take-up shaft 46 is bolted to the drive shaft 45. The take-up shaft 46 is located between the two support columns 44. A rotating belt 47 is wound between the rotating column 42 and the end of the drive shaft 45 away from the motor 37. The cutting gear 49 is rotatably connected to the upper part of the vehicle body 1. The cutting gear 49 is located above the conveyor belt 43 and is in contact with the conveyor belt 43.

[0028] The rotating column 42 is provided with a wave-shaped groove.

[0029] The cutting mechanism includes a sliding bar 51, a sliding column 52, a fixed column 53, a limiting strip 54, a cutting blade 55, and a fixed blade 56. The sliding bar 51 is slidably connected to the fork block 2 and is horizontally arranged. The sliding column 52 is fixedly connected to one side of the top of the sliding bar 51 and is slidably connected to the wave groove of the rotating column 42. Several fixed columns 53 are welded to the fork block 2. Several limiting strips 54 are welded to the top of the sliding bar 51. A cutting blade 55 is fixedly connected to each fixed column 53 and is rotatably connected to each fixed column 53. The cutting blade 55 is slidably connected to the limiting strip 54. A fixed blade 56 is fixedly connected to each fixed column 53.

[0030] In actual operation, the worker pushes the device to the area where the sheep grass needs to be harvested, then starts the motor 37 and moves the vehicle body 1. The rotation of the output shaft of the motor 37 drives the transmission column 34 to rotate, which in turn drives one of the drive gears 361. The rotation of the drive gear 361 drives the other drive gear 361 and the drive shaft 341 to rotate together. The rotation of the drive shaft 341 drives one of the rotating shafts 32 to rotate via the transmission belt 35. The rotation of the rotating shaft 32 drives two of the wheels 33 to rotate, which in turn drives the vehicle body 1, the other two rotating shafts 32, and the wheels 33 to rotate together, causing the vehicle body 1 to move. The movement of the vehicle body 1 drives the fork block 2 to move, which separates the sheep grass on the ground into bundles to prevent the grass from tangling together for subsequent harvesting. At the same time, the rotation of the transmission column 34 drives the rotating column 42 to rotate via the conveyor belt 43. The rotation of the rotating column 42 pushes the sliding column 52 to move back and forth along the wave groove. The left-right reciprocating movement of column 2 causes the sliding bar 51 and several limiting bars 54 to move left-right reciprocating together. The left-right reciprocating movement of the limiting bars 54 causes the cutting blade 55 to swing back and forth. The swinging back and forth movement of the cutting blade 55 continuously opens and closes with the fixed blade 56, cutting the grass between the cutting fork blocks 2, thereby cutting the grass for collection. At the same time, the rotation of the rotating column 42 drives the drive shaft 45 to rotate through the rotating belt 47. The rotation of the drive shaft 45 drives the winding shaft 46 to rotate, and the rotation of the winding shaft 46 winds up the cutting blade. 55. Cut the sheep grass and roll it onto the conveyor belt 43. The conveyor belt 43 rotates and transports the sheep grass. While rotating, the conveyor belt 43 intermittently contacts the cutting gear 49 and intermittently pushes the cutting gear 49 to rotate. The rotating cutting gear 49 crushes the sheep grass on the conveyor belt 43, cutting it into small pieces to prevent the sheep grass from becoming too long and tangled together, which would cause the conveyor belt 43 to get stuck. The rotating conveyor belt 43 transports the cut sheep grass into the vehicle body 1 for collection, thus completing the sheep grass harvesting.

[0031] Example 2: Based on Example 1, as shown in Figures 1-4, a dispersing mechanism is also included. The dispersing mechanism is located on the vehicle body 1 and includes a spiral wheel 61 and a spur gear 62. The spiral wheel 61 is rotatably connected to the vehicle body 1 and is horizontally positioned. The spiral wheel 61 is located above the conveyor belt 43 and is in contact with the conveyor belt 43. The ends of the spiral wheel 61 and the cutting gear 49 near the motor 37 are both connected to the spur gear 62 via a flat key, and the two spur gears 62 mesh.

[0032] The intermittent rotation of the cutting gear 49 drives one of the spur gears 62 to rotate intermittently, which in turn drives another spur gear 62 to rotate intermittently. This, in turn, drives the spiral wheel 61 to rotate intermittently. As the conveyor belt 43 rotates and transports hay, the intermittent rotation of the spiral wheel 61 disperses the hay piled up on the conveyor belt 43, allowing the hay to be spread more evenly on the conveyor belt 43. This enables the cutting gear 49 to cut the hay into smaller pieces more effectively, preventing the hay from tangling around the conveyor belt 43 and the rotating column 42, thus avoiding device malfunctions and allowing for more efficient harvesting of the hay.

[0033] Example 3: Based on Example 2, as shown in Figures 1-7, a cleaning mechanism is also included. The cleaning mechanism is mounted on the vehicle body 1 and includes a fixing strip 71, a cleaning brush 72, a compression spring 73, a pinion 75, protrusions 76, and a compression column 77. The fixing strip 71 is bolted to the upper inner wall of the vehicle body 1. The cleaning brush 72 is slidably connected to the fixing strip 71 and contacts the conveyor belt 43. The compression spring 73 is connected between the fixing strip 71 and the cleaning brush 72 via a hook. The pinion 75 is connected to the side of the cleaning brush 72 near the motor 37 via a flat key. One of the drive shafts 341 meshes with the pinion 75. Several protrusions 76 are welded to the side of the cleaning brush 72 near the motor 37. The compression column 77 is welded to the upper outer wall of the vehicle body 1 near the motor 37 and contacts the protrusions 76.

[0034] Initially, because the extrusion column 77 is pressed against one of the protrusions 76, the extrusion spring 73 is in a stretched state. The rotation of one of the drive gears 361 will drive the pinion 75 to rotate. The rotation of the pinion 75 will drive the cleaning brush 72 and several protrusions 76 to rotate together. The rotation of the cleaning brush 72 will clean the hay adhering to the conveyor belt 43, causing the hay on the conveyor belt 43 to fall completely into the vehicle body 1. The rotation of one of the protrusions 76 will disengage from the extrusion column 77. The return of the extrusion spring 73 will drive the cleaning brush 72 and several protrusions 76 to move away from the motor 37. As the other protrusion 76 continues to rotate, it will contact the extrusion column 77 and be squeezed by the extrusion column 77, resetting towards the direction of the motor 37. The resetting of protrusion 76 will drive the cleaning brush 72 to reset, and the extrusion spring 73 will be stretched. This process is repeated, which in turn drives the cleaning brush 72 to move back and forth. The back and forth movement of the cleaning brush 72 can more thoroughly clean the hay adhering to the conveyor belt 43, allowing the hay on the conveyor belt 43 to fall more thoroughly into the vehicle body 1, and preventing the conveyor belt 43 from throwing the adhering hay out of the vehicle body 1, thus causing waste of hay, thereby achieving efficient harvesting of hay.

[0035] Example 4: Based on Example 3, as shown in Figure 7, it also includes a support rod 8, a scraper frame 81 and a torsion spring 83. The support rod 8 is bolted to the side of the vehicle body 1 near the fork block 2. The scraper frame 81 is rotatably connected to the support rod 8. The scraper frame 81 is provided with several scraping strips. The torsion spring 83 is connected between the scraper frame 81 and the support rod 8.

[0036] When the take-up shaft 46 rotates, it comes into contact with the scraper 81 and pushes the scraper 81 to swing. The torsion spring 83 is twisted. When the take-up shaft 46 continues to rotate, it will disengage from the scraper 81. The torsion spring 83 will reset and drive the scraper 81 to reset. This process is repeated, which in turn causes the scraper 81 to swing intermittently, scraping the hay wrapped around the take-up shaft 46 onto the conveyor belt 43. This reduces the occurrence of hay wrapping around the take-up shaft 46, allowing the take-up shaft 46 to collect hay more fully.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
