Detailed Description
The following description of the embodiments is merely exemplary in nature and is in no way intended to limit the utility model, its application, or uses.
As shown in fig. 1, the boom frame damping mechanism of the self-propelled sprayer of the utility model comprises a middle frame 1 for mounting the boom frame and a lifting frame 2 for connecting a lifting connecting rod. When the spraying machine is used, the inner side ends of the spray rod frames are fixedly connected to two sides of the middle frame 1, and the lifting frame 2 is connected to a lifting connecting rod of the spraying machine.
As shown in fig. 2, the lifting frame 2 includes a left upright 21 and a right upright 22 that are parallel to each other, at least two transverse frames 23 are fixedly connected between the left upright 21 and the right upright 22, and the two uprights and the transverse frames form a rectangular frame structure; the outer side surface of the left upright post 21 is provided with a left upper boss 211, a left middle boss 212 and a left lower boss 213 which are sequentially arranged from top to bottom; the outer side surface of the right upright post 22 is provided with an upper right boss 221, a middle right boss 222 and a lower right boss 223 which are sequentially arranged from top to bottom; a left guide post 214 is fixedly installed between the left upper boss 211 and the left middle boss 212, and a right guide post 224 is fixedly installed between the right upper boss 221 and the right middle boss 222; the left guide post 214 and the right guide post 224 are sleeved with springs 9, and the left guide post 214 and the right guide post 224 are symmetrically arranged; the whole lifting frame 2 is symmetrical left and right with the central axis as the center.
As shown in fig. 3, the middle frame 1 comprises a cross beam 11, a floating beam 12, and a connecting rod 13 hinged between the cross beam 11 and the floating beam 12, wherein the floating beam 12 is parallel to the cross beam 11 and is positioned above the floating beam 12; the floating beam 12 is provided with a through hole 10 for accommodating the left guide pillar 214 and the right guide pillar 224, and the left guide pillar 214 and the right guide pillar 224 on the lifting frame 2 are inserted into the through hole 10; the spring 9 is supported between the lower surface of the floating beam 12 and the upper surface of the left or right center boss 212, 222. The left guide pillar 214 and the right guide pillar 224 limit the floating beam 12 and the whole middle frame 1 to float up and down along the guide pillars, the spring 9 below the floating beam 12 plays a role in buffering and damping, when the spraying machine bumps in the walking process, the vibration of the spray rod frame is transmitted to the middle frame 1 and the floating beam 12, the floating beam 12 moves up and down, and the impact force generated by the vibration is reduced while the spring 9 is compressed.
As shown in fig. 1, the cross beam 11 is located between the left middle boss 212 and the left lower boss 213; the lower baffle 4 is fixedly connected to the ends of the left middle boss 212 and the left lower boss 213 and the ends of the right middle boss 222 and the right lower boss 223, respectively. The lower baffle 4 and two bosses at two ends of the lower baffle form a closed frame together, and the cross beam 11 penetrates through the closed frame to play a role in limiting the swing amplitude of the cross beam 11.
As a further improvement of the utility model, the length of the floating beam 12 is smaller than that of the cross beam 11, hinge bases 15 are fixedly installed at two ends of the cross beam 11, and the connecting rod 13 is hinged between the end of the floating beam 12 and the hinge bases 15. The shorter floating beam 12 makes the structure of the intermediate frame 1 more compact; the arrangement of the hinge seat 15 can facilitate production, installation and maintenance of equipment.
As shown in fig. 3, a longitudinal beam 16 extending upward and a short beam 17 extending outward are fixedly connected to the cross beam 11, an upper cross beam 18 is fixedly connected to the longitudinal beam 16, an outer cross beam 19 is fixedly connected to the short beam 17, the upper cross beam 18 and the outer cross beam 19 are both parallel to the cross beam 11, and the upper cross beam 18 is located above the upper left boss 211. Thus, the upper beam 18, the outer beam 19 and the beam 11 together form a three-dimensional rectangular frame structure, the structural strength is greatly increased, and a hydraulic oil cylinder for driving the spray bar frame to be stored can be arranged on the outer beam 19 as shown in fig. 4. When in use, the inner side ends of the spray rod frames are connected with the end part of the cross beam 11 or the upper end and the lower end of the longitudinal beam 16 through welding or bolt connection or through a hinge shaft. The weight of the spray rod frame is transmitted to the floating beam 12 through the cross beam 11, the spring 9 plays a role in buffering and damping, most of impact force generated when the spray rod frame jolts up and down is eliminated by the spring 9, and the service life of the spray rod frame can be effectively prolonged.
