Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a front-mounted corn stalk cutting and row-rearing device. Background Technology

[0002] Conservation tillage has become a mainstream farming practice in North America, South America, and Oceania, and has also seen some application in my country. Its core principle is to minimize soil tillage and disturbance during crop cultivation, and to use mulching methods such as straw or biomass planting to reduce dust and soil erosion, thereby conserving soil and water, protecting farmland and the ecological environment, while ensuring normal sowing and seedling emergence, ultimately achieving high yields and efficiency. Conservation tillage is primarily applied in dryland agriculture. Currently, in the dryland areas of Northeast China, conservation tillage is categorized into two modes based on the method of straw mulching: stubble mulching and straw crushing mulching.

[0003] The traditional straw mulch conservation tillage method typically involves crushing all straw after the autumn harvest and evenly covering the ground surface, followed by deep tillage before the ground freezes, and then no-till sowing the following spring without any further land preparation. This method suffers from several problems, including straw erosion and uneven coverage, affecting the passage of spring sowing machinery, uneven straw distribution leading to low seedling uniformity, and slow soil temperature rise after sowing. To address these technical issues, this invention provides a pre-positioned corn straw cutting and row-harvesting device. Utility Model Content

[0011] A straightening component is disposed at one end of the rear side of the frame and is located on one side of the conveyor belt, corresponding to the output position of the conveyor belt;

[0012] A movable component is installed at the bottom front side of the frame.

[0013] According to the pre-positioned corn stalk cutting and row harvesting device provided by this utility model, the transmission assembly includes a drive sprocket set and a driven sprocket set. The driven sprocket set is provided in several groups, and the several groups of sprocket sets are respectively installed on the frame. The drive sprocket set is installed on the frame and is axially connected to the rotating shaft. The several driven sprocket sets are respectively connected to the drive sprocket set through chain transmission.

[0014] According to the pre-positioned corn stalk cutting and arranging harvesting device provided by this utility model, the harvesting component includes harvesting rollers, and two sets of harvesting rollers are provided. The two sets of harvesting rollers are symmetrically rotatably connected to the mounting frame. The harvesting rollers are axially connected to the driven sprocket set. There is a gap between the two sets of harvesting rollers. A conical screw is fixedly connected to one end of the harvesting roller. Several strip grooves are equally spaced on the outer wall of the harvesting roller.

[0015] According to the pre-positioned corn stalk cutting and arranging harvesting device provided by this utility model, the cutting mechanism includes a cutter. The cutter is rotatably connected to the mounting frame via a fixed shaft. A protective shell is fixedly connected to the mounting frame. The cutter is located inside the protective shell. The fixed shaft is perpendicularly arranged to the protective shell. The top end of the fixed shaft passes through the protective shell and is fixedly connected to a driven bevel gear. A horizontal shaft is rotatably connected to the mounting frame. A driving bevel gear is fixedly connected to one end of the horizontal shaft. The driving bevel gear meshes with the driven bevel gear. One point of the horizontal shaft is axially connected to the driven sprocket assembly. The axis of the harvesting roller is perpendicular to the axis of the fixed shaft.

[0016] According to the pre-positioned corn stalk cutting and arranging harvesting device provided by this utility model, the arranging component includes an arranging frame, which is fixedly connected to one end of the rear side of the frame. The height of the arranging frame is lower than the height of the top surface of the conveyor belt, and the bottom surface of the arranging frame is higher than the lowest point of the moving component.

[0018] The present invention discloses the following technical effects:

[0019] In operation, the entire front-mounted corn stalk cutting and arranging harvesting device starts working by first starting the motor. The motor drives one of the drive rollers to rotate via a pulley. Due to the transmission effect of the pulley, the other drive roller also rotates, thus achieving synchronous rotation between the two drive rollers. The traction frame is connected to a tractor or other traction equipment, enabling the entire device to move in the field. The harvesting mechanism is connected to one of the drive rollers via a transmission assembly. When the drive roller rotates, the transmission assembly drives the harvesting assembly to rotate, cutting the corn stalks. The cut corn stalks fall onto the conveyor belt and are conveyed to one side of the device as the conveyor belt moves. While the harvesting assembly cuts the stalks, the cutting mechanism works simultaneously, cutting longer stalks into shorter segments. The arranging assembly is located at the output position of the conveyor belt. When the cut stalks are conveyed here, the arranging assembly will organize them into piles or neatly arrange them for subsequent collection and processing, thus covering the rows. The movable assembly at the bottom front of the frame allows the entire device to move flexibly in the field, adapting to different terrains and operational needs.

[0020] This invention uses a cutting mechanism and a harvesting mechanism to cut corn stalks into equal-length segments. A small portion of the cut stalks can be placed in wide rows, while the majority can be placed in narrow rows. Large stalk segments do not pile up due to wind, thus affecting sowing. Harvesting with high stubble allows the cut stalks to be fixed in place. Rotation between wide and narrow rows reduces the difficulty of collecting and storing stalks year after year.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figure 1-4 This utility model provides a front-mounted corn stalk cutting and row-harvesting device, comprising:

[0030] Frame 1, with a traction frame 2 installed at the rear top of frame 1;

[0031] The transmission mechanism includes two transmission rollers 3, which are rotatably connected to the frame 1 via a rotating shaft and are symmetrically arranged. The two transmission rollers 3 are driven by a conveyor belt 4. One end of the rotating shaft passes through the frame 1 and is fixedly connected to a pulley 5. Several pulleys 5 are driven by belts. A motor is installed on the frame 1, and one of the pulleys 5 is connected to the motor shaft.

[0032] A transmission assembly is mounted on frame 1 and is engaged with one of the rotating shafts.

[0033] The harvesting mechanism has several sets of harvesting components on the front side of the frame 1. The harvesting mechanism includes a mounting frame 6 fixedly connected to the front side of the frame 1. The mounting frame 6 is equipped with harvesting components, and the harvesting components are connected to the transmission components.

[0034] The segmentation mechanism consists of several groups, each group corresponding to a number of harvesting components. The segmentation mechanism is connected to the transmission components.

[0035] The straightening component is located at one end of the rear side of the frame 1 and is situated on one side of the conveyor belt 4, corresponding to the output position of the conveyor belt 4.

[0036] Among them, a movable component is installed at the bottom front side of frame 1.

[0037] When this utility model is in operation, the motor is started first when the entire front-end corn stalk cutting and arranging harvesting device begins to work. The motor drives one of the drive rollers 3 to rotate through the pulley 5. Due to the transmission action of the pulley 5, the other drive roller 3 will also rotate, thus achieving synchronous rotation between the two drive rollers 3. The traction frame 2 is connected to a tractor or other traction equipment, enabling the entire device to move in the field. The harvesting mechanism is connected to one of the drive rollers 3 through a transmission assembly. When the drive roller 3 rotates, the transmission assembly drives the harvesting assembly to rotate, cutting the corn stalks. The cut corn stalks fall onto the conveyor belt 4 and are conveyed to one side of the device as the conveyor belt 4 moves. While the harvesting assembly is cutting the stalks, the cutting mechanism works synchronously, cutting longer stalks into shorter segments. The arranging assembly is located at the output position of the conveyor belt 4. When the cut stalks are conveyed here, the arranging assembly will organize them into piles or arrange them neatly for subsequent collection and processing, thus covering the rows. The movable component at the bottom front of frame 1 allows the entire device to move flexibly in the field, adapting to different terrains and operational needs.

[0038] This invention uses a cutting mechanism and a harvesting mechanism to cut corn stalks into equal-length segments. A small portion of the cut stalks can be placed in wide rows, while the majority can be placed in narrow rows. Large stalk segments do not pile up due to wind, thus affecting sowing. Harvesting with high stubble allows the cut stalks to be fixed in place. Rotation between wide and narrow rows reduces the difficulty of collecting and storing stalks year after year.

[0039] The scheme is further optimized. The transmission assembly includes a drive sprocket set 7 and a driven sprocket set 8. The driven sprocket set is provided in several groups. The several groups of sprocket sets are respectively mounted on the frame 1. The drive sprocket set 7 is mounted on the frame 1 and is axially connected to the rotating shaft. The several driven sprocket sets 8 are respectively connected to the drive sprocket set 7 through chain transmission.

[0040] The harvesting assembly is further optimized by including a harvesting roller 9. There are two sets of harvesting rollers 9, which are symmetrically rotatably connected to the mounting frame 6. The harvesting roller 9 is axially connected to the driven sprocket group 8. There is a gap between the two sets of harvesting rollers 9. One end of the harvesting roller 9 is fixedly connected to a tapered screw 10. Several strip grooves are equally spaced on the outer wall of the harvesting roller 9.

[0041] The scheme is further optimized. The cutting mechanism includes a cutter 11, which is rotatably connected to the mounting frame 6 via a fixed shaft 12. A protective shell 13 is fixedly connected to the mounting frame 6. The cutter 11 is located inside the protective shell 13. The fixed shaft 12 is vertically arranged with the protective shell 13. The top end of the fixed shaft 12 passes through the protective shell 13 and is fixedly connected to a driven bevel gear 14. A horizontal shaft is rotatably connected to the mounting frame 6. A drive bevel gear 15 is fixedly connected to one end of the horizontal shaft. The drive bevel gear 15 meshes with the driven bevel gear 14. One point of the horizontal shaft is axially connected to the driven sprocket assembly 8. The axis of the harvesting roller 9 is perpendicular to the axis of the fixed shaft 12.

[0042] Further optimization of the scheme: the straightening component includes a straightening frame 16, which is fixedly connected to one end of the rear side of the frame 1. The height of the straightening frame 16 is lower than the height of the top surface of the conveyor belt 4, and the bottom surface of the straightening frame 16 is higher than the lowest point of the moving component.

[0043] In a further optimized design, the moving component includes a moving wheel 17 and a fixed frame 18. The fixed frame 18 is fixedly connected to the bottom of the front side of the frame 1, and the moving wheel 17 is rotatably connected to the fixed frame 18.

[0044] When the motor starts, the motor shaft drives the drive sprocket assembly 7 to rotate. Since the drive sprocket assembly 7 is shaft-connected to the rotating shaft, the shaft also rotates, thereby driving the connected transmission roller 3 to rotate. Simultaneously, the drive sprocket assembly 7, through chain transmission, engages with several sets of driven sprocket assemblies 8, enabling these driven sprocket assemblies 8 to rotate synchronously. The two sets of harvesting rollers 9 in the harvesting assembly are each driven by the driven sprocket assemblies 8. Because the harvesting rollers 9 have evenly spaced slots, these slots can more effectively grip and cut the corn stalks. The conical screw 10 is designed to assist in the introduction and cutting of the stalks, while reducing stalk tangling during the harvesting process.

[0045] When the driven sprocket assembly 8 rotates, the horizontal shaft connected to it also rotates. The drive bevel gear 15 on the horizontal shaft rotates accordingly and meshes with the driven bevel gear 14, thereby driving the cutter 11 to rotate within the protective housing 13. The movement of the cutter 11 further cuts the long straw cut by the harvesting roller 9 into shorter segments.

[0046] The chopped straw falls onto conveyor belt 4 and is transported to the rear of the device. The sizing frame 16 in the sizing assembly is located at the output position of conveyor belt 4. Its height is designed so that the straw can slide smoothly down and accumulate on the sizing frame 16 to form a neat straw pile.

[0047] The movable wheels 17 in the mobile assembly enable the device to move flexibly in the field and adapt to different working environments. The fixed frame 18 provides stable support for the movable wheels 17, ensuring the stability of the device during movement.

[0048] By optimizing the design of the harvesting roller 9 and the cutter 11, harvesting efficiency and cutting quality can be further improved, reducing straw damage and omissions. The conical screw 10 design can more effectively guide straw into the harvesting area, improving harvesting efficiency.

[0049] Chain drive systems have advantages such as simple structure and high transmission efficiency. By optimizing the design of the chain and sprocket, the stability and reliability of the transmission can be further improved.

[0050] It should be noted that because the stalk harvester needs to cut the straw into sections, it needs to harvest from a high position. That is, it uses the lifting device of the agricultural machine for lifting control, so that the harvesting starts from the top of the straw and continues until a certain height is left at the bottom. This is different from conventional harvesting devices, which cannot directly cut the root.

[0051] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0052] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
