Detailed Description

The following specific embodiments are merely illustrative of the present invention, and are not intended to limit the present invention, and those skilled in the art can make modifications of the present embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent laws and protection within the scope of the present invention.

The scheme is realized by the following technical means:

example (b): in the embodiment, the adjustable working head mounting system for the field plant picking or harvesting mechanical equipment is provided, the system can be provided with different processing working heads 9 on two sides of the front end of the equipment, and meanwhile, the height value, the horizontal position or the distance of the working heads 9 on one side can be independently adjusted according to different plant types and picking and harvesting requirements, so that the system is suitable for picking and harvesting of various plants or other processing requirements.

Functionally, the three-dimensional adjustable working head mounting system provided by the scheme comprises a lifting adjusting mechanism for adjusting the height position of the working head 9 relative to the equipment main body and a translation adjusting mechanism for adjusting the horizontal position of the working head 9 relative to the equipment main body along the horizontal direction.

In order to realize the functions, the three-dimensional adjustable working head mounting system specifically comprises two unit mounting frames 1 which are fixedly mounted in the front end of the equipment main body in a movable mode, wherein the two unit mounting frames 1 are respectively arranged on the left side and the right side of the equipment main body, and are mutually in mirror symmetry relative to a vertical central plane. For the unit mounting frame 1 at one side, the unit mounting frame comprises a connecting mounting base 2 fixedly mounted at the position close to the front end of the cotton picker body, a supporting connecting frame 4 used for being connected with a working head 9, and a main lifting connecting arm 3 arranged between the connecting mounting base 2 and the supporting connecting frame 4. The two ends of the main lifting connecting arm 3 are respectively connected with the connecting mounting base 2 and the bearing connecting frame 4 in a hinged mode, so that the bearing connecting frame 4 can rotate around a first rotating shaft 3a extending along the horizontal direction relative to the main lifting connecting arm 3, the main lifting connecting arm 3 can rotate around a second rotating shaft 3b extending along the horizontal direction, and the first rotating shaft 3a and the second rotating shaft 3b are parallel to each other. With this configuration, the support link 4 and the respective working heads 9 mounted on the support link 4 can be adjusted relative to the floor height in a positive or negative rotation of the main lifting link arm 3 about the second pivot axis 3 b. In the process, because the height of the working head 9 is adjusted by rotating the main lifting connecting arm 3, the working head 9 can be correspondingly turned over, so that the working head 9 cannot be kept in the horizontal or optimal working state with a certain inclination angle, and the cotton collection efficiency is reduced. In view of this problem, it is necessary in this case to perform a counter-adjustment rotation of the cradle connection frame 4 about the first rotation axis 3a with respect to the main arm 3 to adjust and restore the working head 9 to the optimal angular position. Considering that a large force is needed for driving each part to rotate and the position needs to be controlled more accurately, the hydraulic rod group is selected and applied as the driving device. Therefore, a lifting driving connection fulcrum for connecting with an external hydraulic driving rod to realize the lifting action of the bearing connecting frame 4 is arranged on the main lifting connecting arm 3, and an angle adjusting connection fulcrum for connecting with an external hydraulic adjusting rod to keep the working head 9 on the bearing connecting frame 4 in a horizontal state is arranged on the mounting connecting arm 4 c.

The support link 4 mentioned here is configured to be further unfolded, and specifically includes a front mounting rod 4a for connecting with the front portion of the working head 9, a rear mounting rod 4b for connecting with the rear portion of the working head 9, and a mounting link arm 4c connected and installed between the front mounting rod 4a and the rear mounting rod 4b, forming a frame structure that is i-shaped in a top view. In order to shorten the stroke of the adjusting rod group on the premise of realizing accurate adjustment of the turning angle, the mounting connecting arm 4c can be fixed on the upper surfaces of the front mounting rod 4a and the rear mounting rod 4b in a welding mode, meanwhile, the mounting connecting arm 4c protrudes upwards relative to the plane formed by the front mounting rod 4a and the rear mounting rod 4b, and the angle adjusting connecting fulcrum is arranged at the position close to the rear end of the mounting connecting arm 4 c.

In order to ensure that the front mounting rod 4a and the rear mounting rod 4b play a reliable role in supporting and lifting the working heads 9, each working head 9 can move and be adjusted to two sides along the horizontal left-right direction relative to the front mounting rod 4a and the rear mounting rod 4b, so that the plant rows planted in the actual field can be picked or harvested more accurately. Therefore, the front mounting rod 4a and the rear mounting rod 4b are also simultaneously included in the aforementioned translational adjustment mechanism. The translation adjusting mechanism comprises a front mounting connecting assembly and a rear mounting connecting assembly, wherein the front mounting connecting assembly is arranged on the working head 9 and is used for being connected with the front mounting rod 4a, and the rear mounting connecting assembly is used for being connected with the rear mounting rod 4 b. Specifically, the front mounting connection assembly comprises front mounting arms 5 which are fixedly arranged on the left side and the right side of the working head 9 in a row and are symmetrical to each other through welding or bolt fastening connection, a main bearing part 5a which is bent and extends to the upper surface of the front mounting rod 4a in a butting manner is formed at the top of each front mounting arm 5, the rear mounting connection assembly comprises an auxiliary bearing limiting part 6 which is formed by extending the rear end surface of the working head 9 in a backward protruding manner and is used for butting against the upper surface of the rear mounting rod 4b, the auxiliary bearing limiting part 6 is arranged in the middle of the working head 9, and the auxiliary bearing limiting part 6 on the rear side and two main bearing parts 5a on the front side are mutually connected to form an isosceles triangle layout. A roller guide mechanism 7 for guiding the working head 9 to move in the left-right direction is arranged between the main bearing part 5a and the front bearing rod, and the roller guide mechanism 7 comprises a guide strip 7a protruding upwards from the upper surface of the front bearing rod and extending in the left-right direction, and a concave rotary roller 7b movably mounted on the main bearing part 5a and capable of rotating along the central axis in the front-back direction. When the working head 9 is mounted on the bearing connecting frame 4, the notch of the concave rotary roller 7b can be clamped on the upper side of the guide strip 7a, and meanwhile, the auxiliary bearing limiting part 6 which is formed by protruding and extending backwards from the rear part of the working head 9 and mainly plays a role in preventing the working head 9 from overturning abuts against the upper surface of the rear mounting rod 4 b.

Further, as a plurality of working heads 9 with different weights and different sizes may need to be correspondingly installed in the working process, the mounting frame should be extended to two sides according to actual requirements. Therefore, the outer side of the bearing connecting frame 4 can be detachably and replaceably provided with the expansion connecting frames with different specifications and sizes in a bolt fastening connection mode, so that the bearing connecting frame is suitable for more changeable production work requirements. Specifically, as the front mounting rod 4a, the rear mounting rod 4b and the mounting connecting arm 4c are connected and fixed with each other to form a frame structure similar to an i shape, so that the two mounting rods are both in a column shape which is exposed and protrudes outwards. The end part of the hanging rod is far away from the hanging connecting arm 4c, so that the hanging connecting arm 4c has poor supporting effect, and is easy to bend and deform after being continuously stressed or collided, and the position installation accuracy degree of the picking head is influenced; in addition, the rod-shaped structure protruding outwards has certain potential safety hazards, and people are easily injured when the rod-shaped structure is contacted with the rod-shaped structure. Therefore, a U-shaped extended connecting frame is selected, limit connecting pieces 4d extending in the vertical direction are integrally formed on the inner side end faces of the extended connecting frame and the outer end faces of the mounting rods, after two ends of the U-shaped extended connecting frame are respectively butted with the outer end portions of the front mounting rod 4a and the rear mounting rod 4b, a plurality of bolts simultaneously penetrate through mutually butted and jointed sheet-shaped connecting portions and then are locked and fixed through nuts, and the extended connecting frame and the bearing connecting frame 4 are directly connected and fixed. In addition, the front section of the limit connecting piece 4d is also protruded forward to form a limit end 401 which is positioned outside the guide strip 7a, so that the work head 9 can be prevented from slipping and separating from the guide strip 7a when moving outwards, and the damage to parts of the work head 9 or other dangers can be avoided.

In order to realize the fixing effect of the working head 9 at a specific position in the horizontal direction, a locking and positioning mechanism 8 for fixing the working head 9 is further arranged between the front suspension arm 5 and the front bearing rod. For example, the locking and positioning mechanism 8 may be provided with a plurality of positioning and locking holes on the front end surface of the front mounting rod 4a, and a corresponding positioning and through hole on the front mounting arm 5, when the working head 9 is moved and adjusted to a specific position, a bolt is used as a locking member to sequentially pass through the positioning and locking holes, so as to achieve a reliable locking effect.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope of the present invention, and these modifications or replacements should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
