[0021] In use, the operator installs the cutting conveying mechanism 2 to be tested, i.e. the furrow dividing assembly 21, the cutting assembly 22 and the transverse conveying assembly 23, behind the rear output end of the stem conveying mechanism 1, inserts the hemp stems or simulated stems into the positioning seat 13 of the stem conveying mechanism 1, and the conveying chains 11 are arranged in a row, simulating the actual row of hemp plants; when the first motor 12 is started, the hemp stems or simulated stems are conveyed to the cutting conveying mechanism 2, the performance of the furrow dividing assembly 21 is tested first, and when the conveying chains 11 convey and the furrow dividing assembly 21 guides the stems to the cutting assembly 22, the cutting assembly 22 performs performance testing on the stems, the upper stems after cutting are conveyed to the side by the transverse conveying assembly 23, and the performance of the transverse conveying assembly 23 is tested; the roots of the cut stems are conveyed back to the input end of the conveying chain 11, and the operator can replace the stems and repeat the test of the required items. Before testing, the operator can adjust the speed of the first motor 12, the second motor 221 and the third motor 230 through the control module 0, and then adjust the feeding speed of the corresponding conveying chain 11, the cutting speed of the cutting assembly 22 and the conveying speed of the transverse conveying assembly 23, so as to obtain the optimal running speed under different speeds, and then apply it to the running speed of each mechanism when the actual harvester cuts hemp, so as to improve the actual harvesting success rate and harvesting quality; and the cumulative test under different speeds can test the service life of each component and the stability of cumulative operation under a certain intensity, so as to test the quality of the components and balance under different speeds and intensities, so that the components can ensure the harvesting efficiency and quality under the premise of ensuring the running stability.

[0022] As an improved embodiment, the stem conveying mechanism 1 further comprises a sliding frame 14 for installing the conveying chain 11 and the first motor 12 and a base 15 for slidingly arranging the sliding frame 14, the sliding frame 14 and the base 15 are slidably connected through the transverse sliding rail 16, and the driving cylinder 17 is arranged on the base 15, the driving cylinder 17 is connected to the sliding frame 14 and drives the sliding frame 14 to slide transversely when started, the transverse sliding direction is perpendicular to the arrangement and running direction of the conveying chain 11, so as to adjust the transverse position of the conveying chain 11, so that the hemp stems or simulated stems on the conveying chain 11 change the positions of the furrow dividing assembly 21 and the cutting assembly 22.

[0023] As Figure 1 , 2As shown, when adjustment is needed, the sliding frame 14 is driven by the driving cylinder 17 to slide along the slide rail 16 on the base 15, so that the conveying chain 11 corresponds to different positions of the separating assembly 21 and the cutting assembly 22, and the performance of the separating assembly 21 and the cutting assembly 22 is tested more comprehensively according to the needs. For example, the separating assembly 21 has a structure position that does not change, and when the stem position does not have a guide channel directly opposite the separating assembly 21, the stem will come into contact with the angle plate of the separating assembly 21 and guide the stem to converge into a gradually narrowing guide channel. After the position of the conveying chain 11 is adjusted, the state of the stem contacting the separating assembly 21 and being guided in different corresponding positions can be simulated, and the performance of the separating assembly 21 is tested more comprehensively to ensure the performance of the parts themselves or the installation accuracy. For example, the cutting assembly 22, in the overall transverse position, whether it can stably complete the cutting when receiving stems in different corresponding positions, and then test the performance and running stability of the cutter in the entire transverse position of the cutting assembly 22. Preferably, the driving cylinder 17 can be used in cooperation with a solenoid valve, and the driving cylinder 17 is started and stopped by the start and stop of the solenoid valve, so that the sliding frame 14 can be flexibly stopped at the required position.

[0024] As an improved specific embodiment, the control module 0 is signal connected to the driving cylinder 17, and the start and stop of the driving cylinder 17 is controlled by the operator at the control module 0, and the driving cylinder 17 can be selectively started and stopped intermittently according to the running time of the first motor 12, the second motor 221 and the third motor 230, so that the transverse position of the conveying chain 11 changes in real time.

[0025] In the above embodiment, the operator can set the control module 0 to start and stop the driving cylinder 17 when the test bench is running, that is, to adjust the transverse position of the conveying chain 11 when the conveying chain 11 is running, so that the simulated environment of the test is more flexible and realistic. The real-time transverse position adjustment can simulate the situation that the stems are shaken by the actual wind or the stems are irregularly arranged due to the growth environment, so that the performance of the cutting conveying mechanism 2 is tested more comprehensively, and the desired test effect is achieved.

[0026] As an improved specific embodiment, the bottom of the sliding frame 14 is provided with a roller 18.

[0027] As shown in Figure 1 , 2 By providing the roller 18, on the one hand, the roller 18 provides support for the whole sliding frame 14, so that the structure is stable; on the other hand, when the sliding frame 14 is driven to move by the driving cylinder 17, the external resistance is smaller, the pressure between the sliding frame 14 and the slide rail 16 is reduced, the transverse movement of the sliding frame 14 is more stable, and the vibration and wear of the parts during debugging are reduced.

[0031] As shown in Figure 1 , 3 , because the stem is inserted into the positioning seat 13, the overall center of gravity is high, the stem will tilt to one side, and then give a overturning force to the conveying chain 11, which will affect the stability of the conveying chain 11; the conveying chain 11 is wound on the chain wheel at both ends and has high strength, and the middle part of the conveying chain 11 arranged and running in the direction has the weakest strength and is most prone to instability and accelerated wear and even damage due to the overturning force; the further provided support strip 111 arranges the conveying chain 11 by means of the through hole 112, limits the overturning of the conveying chain 11 to both sides in a matched shape without affecting the running of the conveying chain 11 along the length direction, so as to ensure the stability of the conveying chain 11 conveying the positioning seat 13 and the stem thereon.

[0033] As shown in Figure 1 , on one hand, through the first motor 12, the two groups of conveying chains 11 can be driven at the same time, the cost of the components is effectively controlled, and it is beneficial to keep the speeds of the two groups of conveying chains 11 consistent, and correspond to different positions of the separating assembly 21 and the cutting assembly 22; on the other hand, the driving gears 121 and the driven gears 122 are engaged in a manner, so that the rotating directions of the conveying chains 11 on the two sides are different, so that the conveying chains 11 on the two sides convey in different stress states to the separating assembly 21 and the cutting assembly 22, because the turning directions are different, the dumping directions of the stems will be different, so that the stems are tested by the separating assembly 21 and the cutting assembly 22 in different stem states when the stems run to the separating assembly 21 and the cutting assembly 22; and when necessary, the turning of the first motor 12 is changed, so that the rotating directions of the conveying chains 11 on the two sides are changed, so that the corresponding separating assembly 21 and cutting assembly 22 of the conveying chains 11 on the two sides can be tested in two stem dumping states, and the overall test efficiency is improved.

[0034] As an improved specific embodiment, the cutting conveying mechanism 2 further comprises an arrangement frame 20, the transverse conveying assembly 23 comprises an upper conveying assembly 231 and a lower conveying assembly 232 arranged in an up-down arrangement on the arrangement frame 20, the lower conveying assembly 232 is correspondingly arranged behind the separating assembly 21, and the upper conveying assembly 231 is adjusted in height on the arrangement frame 20 through the lifting assembly 24.
