[0060] like Fig.10 As shown, according to this embodiment, preferably, the hoisting mechanism 7 includes a mounting plate 701 and a bearing support 702;

[0061] The mounting plate 701 is provided with a transverse through hole; both ends of the driving shaft of the picking drum 2 are respectively installed in the through holes of the mounting plates 701 on both sides through bearing supports 702, which are used to adjust the front and rear position of the picking drum 2 in the horizontal direction.

By counting the total number of peppers collected in the collecting box 4 and the number of broken peppers, the picking rate, loss rate and damage rate of the peppers picked by the picking roller 2 are evaluated, and then the rationality of the structural parameters and motion parameters of the experimental device are judged.

[0069] If the clean picking rate, loss rate and damage rate of picked peppers are not ideal under a certain set of structural parameters, position parameters and motion parameters, the position, structural parameters and motion parameters of the above key components will be gradually adjusted until better picking performance is achieved.

[0072] The spring tooth fixing support 203 is an open channel steel, with an opening on one side of the open channel steel for the long arm of the spring tooth 204 to pass through. A rigid buckle is welded inwardly on the open side of the open channel steel to limit the position movement of the short arm of the spring tooth 204. Such a structural design and installation method can quickly and conveniently replace the spring tooth 204, avoiding the removal and installation of the bolt when replacing the spring tooth 204.

[0073] The left end shaft 201 and the right end shaft 209 of the driving shaft are solid shafts to improve the reliability of the structure, and the middle section of the driving shaft is a hollow shaft, the goal of which is to make the mechanism lightweight.

[0074] The pepper picking experimental device of the present invention can carry out multi-factor and multi-level picking experiments. The orthogonal experimental design method is used to design the experiment. The clean picking rate, loss rate and damage rate of pepper picking are used as performance evaluation indicators. By analyzing the pepper picking performance under different structural parameters, position parameters and motion parameters, the optimal parameter combination is selected to provide basic data for the design of the pepper harvester.

[0075] The working process of the present invention is:

[0076] The second motor 10 drives the picking drum 2 to rotate through the power transmission system 8, and the motor pulls the carrier 12 carrying peppers to move toward the picking drum 2. When the rotating picking drum 2 contacts the pepper plants, the pepper fruits are picked and then thrown onto the material conveying device 3 at the rear. The material conveying device 3 conveys the pepper fruits and the mixture thereof to the collecting box 4.

[0077] After an experiment is completed, the total number of peppers in the aggregate box 4 and the number of broken peppers are counted, and the picking rate, loss rate and damage rate of the peppers picked by the picking roller 2 are evaluated, and then the rationality of the structural parameters and motion parameters of the experimental device are judged, and the structural parameters or position parameters that need to be adjusted are determined.

[0078] The multiple parameters described in the present invention include the following adjustable structural parameters, position parameters, and motion parameters, including the diameter of the picking roller 2, the spatial installation position, the gap between the picking roller 2 and the guide plate 14, the replacement of the guide plate 14 with different curvature radii, the replacement of the spring teeth 204 with different cross-sectional diameters, the rotation speed of the picking roller 2, and the running speed of the carrier 12.

[0079] The patent of the present invention adjusts the spatial position of the picking roller 2 in the following manner: loosen the fastening bolts, move the picking roller 2 forward and backward along the opening direction of the supporting mounting plate 701, move it to the desired position and lock the bolts; loosen the fastening bolts, move the picking roller 2 upward or downward along the long slide groove direction in the vertical bracket 103, move it to the desired position and lock the bolts, thereby realizing the spatial position control of the picking roller 2.

[0080] The present invention adjusts the diameter of the picking drum 2 in the following manner: the outer edge opening of the outer flange 207 is combined with the inner edge protrusion of the inner flange 208, and then bolts are passed through the circular holes at the joint interface of the outer flange 207 and the inner flange 208 to lock them, so that the outer flange 207 and the inner flange 208 can be connected as a whole, thereby increasing the diameter of the picking drum. When the outer flange 207 is removed from the inner flange 208, leaving only the inner flange 208 as the end face of the picking drum, the diameter of the picking drum is reduced.

[0081] The present invention can replace the spring tooth 204 quickly and conveniently in the following manner: a rigid buckle is welded inside the channel steel used for the spring tooth fixing support 203 along one side of the opening, and the required spring tooth 204 is pressed into the rigid buckle by pressure, thereby limiting the movement of the spring tooth. When the original spring tooth 204 is to be removed, the short arm end of the spring tooth 204 can be pried with a screwdriver to conveniently remove the original spring tooth 204.

[0082] The present invention replaces the guide plate 14 quickly and conveniently in the following manner: the guide plate 14 is connected to the frame 1 through a steel sheet 102 with a circular hole, a square hole on the guide plate 14, and a pin shaft. The opening of the pin shaft is manually straightened and the pin shaft is removed, and the guide plate 14 and the frame 1 are automatically separated. Then, the required guide plate 14 is replaced, and the rigid circular ring is used again to connect the guide plate 14 to the circular hole on the frame 1, thereby completing the convenient replacement of the guide plate 14.

[0083] The present invention conveniently regulates the rotation speed of the motor through the motor control system, and the change of the motor rotation speed drives the change of the rotation speed of the picking drum 2 and the forward speed of the carrier 12 through the transmission mechanism.

[0084] After each experiment is completed, the total number of peppers in the aggregate box 4 and the number of broken peppers are counted, and the picking rate, loss rate and damage rate of the peppers picked by the picking roller 2 are evaluated, and then the rationality of the structural parameters and motion parameters of the experimental device are judged, and the structural parameters or position parameters that need to be adjusted are determined, and the optimal parameter combination is selected.

[0085] Through the multi-factor and multi-level experiments carried out above, the optimal parameter matching scheme was selected, which improved the picking performance of peppers and promoted the healthy development of the pepper industry.

[0086] In view of the differences in the harvesting environment, growth conditions, physical and mechanical properties of peppers, and the defect that the key components of the pepper harvester are fixed and cannot be adjusted, which leads to the problem of mismatch between the structural parameters and motion parameters of the pepper harvester, the present invention provides a multi-parameter adjustable pepper picking experimental device for use in pepper harvesting experiments to achieve matching optimization of key parameters.

[0087] The experimental device mainly includes a frame 1, a picking roller 2, a material conveying device 3, a collecting box 4, a first motor 6, a hoisting mechanism 7, a power transmission system 8, a second motor 10, a guide rail 11, a carrier 12, a rice pressing wheel 13 and a guide plate 14.

[0088] The diameter of the picking drum 2, the spatial installation position, the shape of the guide plate 14, the gap between the picking drum 2 and the guide plate 14, the rotation speed of the picking drum 2, and the running speed of the carrier 12 of the experimental device can be easily adjusted or replaced. The present invention realizes a multi-parameter adjustable pepper picking function, reduces the loss rate and damage rate during the pepper picking process, and improves the quality of mechanized pepper picking.
