Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, and particularly relates to a cutting test bench with adjustable multi-parameters of stalks. Background Art

[0002] Cutting is an important process of farm operation machinery such as crop harvesting machinery and straw chopping machinery. Reciprocating cutting is widely used in crop harvesting machinery. Studying the flatness of crop stalk cutting has certain significance for efficient crop harvesting, energy conservation and improvement of the agricultural ecological environment.

[0003] At present, certain research has been carried out on crop stalk cutting test benches at home and abroad. For example, Chinese Patent CN109085081A discloses a multi-functional reciprocating cutting test bench for crop stalks, which can realize cutting tests with different cutting parameters. However, the rotation speed of the auger on the cutting table cannot be adjusted. The auger on the cutting table is also called a screw conveyor, which is used to transport the cut stalks into the bin. Especially when the density of the stalks is relatively large during the test, the fixed transmission speed of the screw conveyor is not conducive to the transportation of the stalks, and it is easy to cause the problem of blockage due to untimely transportation of the screw conveyor, making it difficult to simulate the real situation after field stalk harvesting.

[0004] Therefore, the existing technology still needs to be improved and developed. Content of the Utility Model

[0080] Please refer to Figures 1 to 5 As shown, the present application provides a multi-parameter adjustable cutting test bench for stalks, including a guide rail 100, a clamping mechanism 200, a frame 400, a power mechanism 300, a cutting assembly, a parameter acquisition mechanism, and a control platform 500. The clamping mechanism 200 is arranged on the guide rail 100 for clamping the stalks. The frame 400 is slidably arranged on the guide rail 100. The power mechanism 300 is arranged on the guide rail 100 and is connected to the frame 400 for driving the frame 400 to move on the guide rail 100. The cutting assembly includes a bucket 610, a screw conveyor, a cutter 620, a reel 630, a conveyor 640, and a weighing bin 650. The reel 630, the bucket 610, and the weighing bin 650 are sequentially arranged on the frame 400. The reel 630 is located above the front end of the bucket 610. The cutter 620 is arranged at the bottom of the front end of the bucket 610. The screw conveyor is arranged in the bucket 610. One end of the conveyor 640 is connected to the bucket 610, and the other end is connected to the weighing bin 650. The parameter acquisition mechanism is electrically connected to the screw conveyor, the cutter 620, the reel 630, and the conveyor 640 for acquiring the speeds of the screw conveyor, the cutter 620, the reel 630, and the conveyor 640. The control platform 500 is arranged on one side of the guide rail 100. The parameter acquisition mechanism is electrically connected to the control platform 500.

[0081] Specifically, in this embodiment, a cutting test bench is disclosed. By connecting the screw conveyor, the conveyor 640, the reel 630, and the power mechanism 300 to the parameter acquisition mechanism, and connecting the parameter acquisition mechanism to the control platform 500, the parameter acquisition mechanism can detect the speeds of the screw conveyor, the conveyor 640, the reel 630, and the power mechanism 300 in real time. The user can control the control platform 500 according to the test requirements to conduct crop stalk cutting tests at various speeds. At the same time, by continuously adjusting the speeds of the screw conveyor and the conveyor 640, a better speed ratio can be tested, and the problem that the screw conveyor and the conveyor 640 are prone to blockage is solved.

[0082] Further, the guide rail 100 is used for the cutting assembly to travel, simulating the travel path of cutting the stalks. On the other hand, the shape of the guide rail 100 can be made according to the usage scenario. For example, the guide rail 100 is a curved guide rail 100, which can simulate the test data of cutting stalks on a curved path. For example, the guide rail 100 is a straight guide rail 100, which can simulate the test data of cutting stalks on a straight path, enabling the device to support more test items and functions. Preferably, the guide rail 100 is a double-row straight guide rail 100, and the frame 400 is provided with wheels corresponding to the double-row straight guide rail 100, so that the frame 400 can smoothly move on the double-row straight guide rail 100.

[0083] Further, the cutting assembly includes a bucket 610, a screw conveyor, a cutter 620, a reel 630, a conveyor 640, and a weighing bin 650. The reel 630 is located above the front end of the bucket 610. When cutting the stalks, the reel 630 first contacts the stalks. The reel 630 is used to guide the stalks, prevent the stalks from falling forward, ensure that the stalks are in the best cutting position, and improve the cutting efficiency and quality. At the same time, the cutter 620 on the bucket 610 cuts the stalks, and the cut stalks fall onto the screw conveyor in the bucket 610. The screw conveyor conveys the cut stalks to the conveyor 640, and then the conveyor 640 conveys them into the weighing bin 650. The cutting assembly in this application can not only guide the cutting of the stalks, but also collect the cut stalks, which is beneficial to the progress of the test and convenient for repeated use.

[0084] In another embodiment of the present application, the parameter acquisition mechanism includes a first torque sensor, a second torque sensor, a third torque sensor, a fourth torque sensor, a first speed sensor, a second speed sensor, a third speed sensor, a fourth speed sensor, and a pressure sensor. The first torque sensor is disposed on the screw conveyor and electrically connected to the control platform 500 for detecting the torque of the screw conveyor. The second torque sensor is disposed on the reaper 630 and electrically connected to the control platform 500 for detecting the torque of the reaper 630. The third torque sensor is disposed on the conveyor 640 and electrically connected to the control platform 500 for detecting the torque of the conveyor 640. The fourth torque sensor is disposed on the power mechanism 300 and electrically connected to the control platform 500 for detecting the torque of the power mechanism 300. The first speed sensor is disposed on the screw conveyor and electrically connected to the control platform 500 for detecting the speed of the screw conveyor. The second speed sensor is disposed on the reaper 630 and electrically connected to the control platform 500 for detecting the speed of the reaper 630. The third speed sensor is disposed on the conveyor 640 and electrically connected to the control platform 500 for detecting the speed of the conveyor 640. The fourth speed sensor is disposed on the power mechanism 300 and electrically connected to the control platform 500 for detecting the speed of the power mechanism 300. The pressure sensor is disposed on the cutter 620 and electrically connected to the control platform 500 for detecting the pressure of the cutter 620.

[0085] Specifically, in the present application, a plurality of sensors are provided to detect the torque and speed of the screw conveyor, the reaper 630, the conveyor 640, and the power mechanism 300. The detected data is then sent to the control platform 500. The control platform 500 records each parameter data in real time, and then by continuously adjusting the respective parameter data of the screw conveyor, the reaper 630, the conveyor 640, and the power mechanism 300, it is beneficial to the stem cutting test of the stem cutting test bench under different parameter data. At the same time, by continuously adjusting the respective parameter data of the screw conveyor, the reaper 630, the conveyor 640, and the power mechanism 300, it is also beneficial to find the optimal parameter ratio, making the test more accurate and reliable.

[0086] Furthermore, by providing a pressure sensor on the cutter 620 to detect the pressure of the cutter 620 in real time, the pressure sensor then sends the pressure data to the control platform 500, enabling the user to understand the cutting pressure of the cutter 620, which is beneficial to analyzing the service life of the cutter 620 and the cutting condition of the stem.

[0087] See Figures 6 to 8As shown, in another embodiment of the present application, the clamping mechanism 200 includes square steel 210 and a clamping assembly. A plurality of the square steel 210 are arranged along the length direction of the guide rail 100, and a plurality of the clamping assemblies are all arranged on the square steel 210 and are used for clamping the stalks.

[0088] Specifically, by arranging the square steel 210 between the guide rails 100 and arranging the clamping assembly on the square steel 210, the clamping assembly can be used for clamping the stalks, so that the stalk cutting test bench can also perform stalk cutting tests with different plant spacings and different row spacings, simulate the stalk cutting tests under different planting modes, meet the requirements of more test items, and expand the functions of the test bench.

[0089] See again Figures 6 to 8 As shown, in another embodiment of the present application, the clamping assembly includes a positioning seat 221, a clamp seat 222, a connecting rod 223, an operating rod 224, a rotating rod 225 and an elastic member 226. The positioning seat 221 is arranged on the square steel 210, the clamp seat 222 is arranged on the square steel 210, a first hinge portion 2221 and a second hinge portion 2222 are arranged on the clamp seat 222, one end of the connecting rod 223 is hinged to the first hinge portion 2221, a third hinge portion 2241 and a fourth hinge portion 2242 are arranged on the operating rod 224, the third hinge portion 2241 is hinged to the other end of the connecting rod 223, the upper part of one end of the rotating rod 225 is hinged to the second hinge portion 2222, and the lower part of the same end is hinged to the fourth hinge portion 2242. The elastic member 226 is arranged at the other end of the rotating rod 225. Wherein, when the operating rod 224 rotates counterclockwise, it drives the rotating rod 225 to rotate clockwise, and the elastic member 226 abuts against the positioning seat 221 to form a clamping space for inserting the stalk, the first hinge portion 2221, the third hinge portion 2241 and the fourth hinge portion 2242 are collinear, and the operating rod 224 is self-locking; when the operating rod 224 rotates clockwise, it drives the rotating rod 225 to rotate counterclockwise, and the elastic member 226 moves away from the positioning seat 221.

[0090] Specifically, the clamping assembly provided in this embodiment includes a positioning seat 221, a clamping seat 222, a connecting rod 223, an operating rod 224, a rotating rod 225, and an elastic member 226. When the operating rod 224 rotates counterclockwise, it drives the rotating rod 225 to rotate clockwise. The elastic member 226 abuts against the positioning seat 221 to form a clamping space for inserting the stalk. The elastic member 226 clamps the stalk tightly, and the size of the clamping space can be adjusted according to the thickness of the stalk. At the same time, the first hinge portion 2221, the third hinge portion 2241, and the fourth hinge portion 2242 are collinear, and the operating rod 224 achieves self-locking. When the operating rod 224 rotates clockwise, it drives the rotating rod 225 to rotate counterclockwise, and the elastic member 226 moves away from the positioning seat 221, and the elastic member 226 releases the stalk. In this application, through the provided clamping assembly, on the one hand, the structure of the manual clamping method is relatively simple, the operation is very convenient, and the clamping pressure can be adjusted by the user himself, improving the clamping efficiency of the clamping mechanism 200. On the other hand, the size of the clamping space can be adjusted according to the thickness of the stalk, so that stalks of different thicknesses can be clamped, and further meet the project requirements of more stalk cutting tests, expanding the functions of the test bench.

[0091] Further, the range of the clamping space is 7 - 18 mm.

[0092] See Figures 6 to 8 As shown, in another embodiment of the present application, the power mechanism 300 includes two power seats 310, a power motor 320, two power rotating shafts 330, four power wheels 340, and two power ropes 350. The two power seats 310 are arranged at the head end and the tail end of the guide rail 100. The power motor 320 is arranged on one of the power seats 310. The two power rotating shafts 330 are arranged on the two power seats 310. One of the power rotating shafts 330 is connected to the power motor 320. The two power wheels 340 are arranged at both ends of the power rotating shaft 330. The other two power wheels 340 are arranged at both ends of the other power rotating shaft 330. One end of the power rope 350 is wound around the power wheel 340 on one side and is connected to the left side of the front end of the frame 400. The other end is wound around the other power wheel 340 on the same side and is connected to the left side of the rear end of the frame 400. One end of the other power rope 350 is wound around the power wheel 340 on the other side and is connected to the right side of the front end of the frame 400. The other end is wound around the other power wheel 340 on the same side and is connected to the right side of the rear end of the frame 400.

[0093] Specifically, the power mechanism 300 provided in this embodiment includes two power seats 310, a power motor 320, two power rotating shafts 330, four power wheels 340, and two power ropes 350. AsFigure 8 As shown, the driving wheels 340 on the two different driving rotating shafts 330 on the left side and the driving rope 350 on the left side form a pulley block. The two ends of the driving rope 350 on the left side are respectively connected to the left front end and the left rear end of the frame 400. Another pulley block is formed by the driving wheels 340 on the two different driving rotating shafts 330 on the right side and the driving rope 350 on the right side. The two ends of the driving rope 350 on the right side are respectively connected to the right front end and the right rear end of the frame 400. Then, the driving motor 320 can be installed at the front end or the rear end of the guide rail 100. The driving motor 320 is connected to any one of the driving rotating shafts 330 through a power transmission component, so that the frame 400 moves on the guide rail 100 through the setting of the driving motor 320. It should be noted that the power transmission component includes two driving gears and a driving chain. One driving gear is arranged on the output shaft of the driving motor 320, and the other driving gear is arranged on the corresponding driving rotating shaft 330. The two driving gears are connected by a driving chain. In this application, through the arranged power mechanism 300, the left side and the right side of the frame 400 can be pulled simultaneously, making the movement of the frame 400 on the guide rail 100 more stable and reliable. In addition, the user can set the forward or reverse rotation of the driving motor 320 through the control platform 500, so that the frame 400 can reciprocate on the guide rail 100, and then can reciprocally cut the stalks to meet the needs of more test items.

[0094] See Figure 2 and Figure 3 As shown, in another embodiment of the present application, the screw conveyor includes a screw rotating shaft 612, screw blades 611 and a screw motor 613. The screw rotating shaft 612 is rotatably arranged in the bucket 610. The screw blades 611 are arranged on the screw rotating shaft 612. The screw motor 613 is arranged on the frame 400 and is connected to the screw rotating shaft 612 for driving the screw rotating shaft 612 to rotate. The screw motor 613 is electrically connected to the control platform 500.

[0095] Specifically, for the specific structure of the screw conveyor provided in this embodiment, the screw conveyor is arranged in the bucket 610. After the cutter 620 at the front end of the bucket 610 cuts the stalks, the stalks fall into the bucket 610 and are then conveyed to the conveyor 640 through the screw blades 611, the screw rotating shaft 612 and the screw motor 613 in the bucket 610, so that the cut stalks can be recycled in time.

[0096] Furthermore, the screw motor 613 is installed on the conveyor 640, reducing the assembly difficulty of the screw motor 613 and making the device structure simpler.

[0097] Furthermore, as Figure 5As shown, the spiral motor 613 is connected to the spiral rotating shaft 612 through a spiral transmission assembly. The spiral transmission assembly includes a spiral gear and a spiral chain. One spiral gear is arranged on the output shaft of the spiral motor 613, and the other is arranged on the spiral rotating shaft 612. The two spiral gears are connected by the spiral chain, so that the spiral motor 613 can drive the spiral rotating shaft 612.
