Description

Technical Field

[0001] The invention relates to the technical field of fruit picking, in particular to a litchi fruit picking device. Background Art

[0002] As a specialty fruit in southern my country, litchi has the largest cultivation area and the largest output in the world. There are many varieties and brands of litchi, which are gradually being commercialized and facing the international market. The litchi industry is constantly being optimized and upgraded.

[0003] When picking lychee fruits in a small space or studying lychee varieties at a high place, high-altitude picking shears are usually used. The high-altitude picking shears usually include a telescopic rod and a shearing knife and a clamping jaw at the end of the telescopic rod. An actuator for controlling the movement of the shearing knife is provided at the tail of the telescopic rod. When in use, the shearing knife is moved to the branch above the lychee fruit, and the movement of the controlling actuator drives the shearing knife to move, cuts the branch and separates it from the fruit tree, and when the shearing knife cuts the branch, the clamping jaw is linked to clamp the branch (avoiding the lychee fruit from falling to the ground and being damaged), and then the telescopic rod is operated to move the clamping jaw and the lychee fruit to a material receiving frame placed on the ground, and finally the actuator is released to cause the clamping jaw to move in the opposite direction to release the clamping of the branch. At this time, the picked lychees fall into the material receiving frame for collection.

[0004] In the above operation, each time a litchi fruit is cut, the telescopic rod needs to be adjusted from the high position of the branch to the low position of the material holding frame to collect the litchis. During the entire litchi fruit picking process, the telescopic rod needs to be frequently adjusted up and down. In this way, the number of times the litchi fruits are cut is reduced in the same time, which not only reduces the litchi fruit picking efficiency, but also increases the labor intensity of the operator.

DETAILED DESCRIPTION

[0037] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0038] Combined with Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, a litchi fruit picking device comprises a telescopic rod 1, a movable end of the telescopic rod 1 is provided with a detachable mounting seat 111, a mounting plate 112 is provided on the mounting seat 111, and further comprises:

[0039] A shearing assembly 2, wherein the shearing assembly 2 comprises a fixed seat 211 arranged on the inner wall of a mounting plate 112, a rotating shaft 212 fixedly arranged on the fixed seat 211 and two shearing knives 213 for use with the fixed seat 211 are hingedly connected to the rotating shaft 212, a detachable arc seat 214 is arranged on the mounting plate 112 corresponding to the front end of the shearing knives 213, hinge seats 215 are arranged on the opposite end surfaces of the two shearing knives 213, a sliding rod 216 is hingedly connected to the hinge seat 215, a cylinder 217 slidably matched with the sliding rod 216 is fixedly arranged on the mounting plate 112, and a return spring is fixedly arranged between the sliding rod 216 and the bottom wall of the cylinder 217;

[0040] The transmission assembly 3 is arranged on the mounting plate 112 and drives a slide bar 216 to slide, thereby driving a shearing knife 213 to move. The linkage assembly 4 is arranged on the fixing seat 211 and drives the two shearing knives 213 to perform relative synchronous movements. The actuator assembly 5 is arranged on the telescopic rod 1 and controls the movement of the transmission assembly 3.

[0041] Auxiliary material unloading component 6, the auxiliary material unloading component 6 comprises a material receiving barrel 611 detachably arranged on the bottom surface of the mounting plate 112, the bottom surface of the material receiving barrel 611 is provided with a material guiding barrel 1 612 of an L-shaped structure, the material guiding barrel 1 612 is sleeved with a material guiding barrel 2 613 of sliding fit, and the material guiding barrel 1 612 and the material guiding barrel 2 613 are detachably connected to the telescopic rod 1 through the setting of a support frame 616, and the material receiving barrel 611, the material guiding barrel 1 612 and the material guiding barrel 2 613 are plastic products with a wall thickness of 0.6-1mm;

[0042] In order to store the cut lychees, a material holding component 7 is also provided, which includes a diagonal shoulder strap 711 and a detachable material holding frame 712 on the diagonal shoulder strap 711. During the picking process, the lower end of the material guide barrel 613 corresponds to the inner cavity of the material holding frame 712, and the end of the material holding frame 712 close to the user's body is provided with a body guard seat 713. The end face of the body guard seat 713 is an arc-shaped structure and a sponge is embedded in this arc-shaped structure. In this way, when the user carries the material frame 712 at an angle, direct contact between the material frame 712 and the user's body is avoided, thereby ensuring comfort during use.

[0043] Through the above structure, the operator first carries the material frame 712 on the side of the body through the oblique shoulder strap 711, and operates the telescopic rod 1 to pick the litchi fruits at a high place (during the picking process, the material guide cylinder 1 612 and the material guide cylinder 2 613 are in a tilted state with the telescopic rod 1). When picking, the lower part of the material guide cylinder 2 613 is aligned with the inner cavity of the material frame 712, and then the left end of the mounting plate 112 is covered with litchi fruits, and then the operator moves to the left, driving the telescopic rod 1 and the shear knife 213 to move to the left, so that the litchi fruits are picked. The branches above the fruit are located between the two shearing knives 213, and then the execution component 5 is controlled to drive the transmission component 3 to move, and then drive a sliding rod 216 to slide, and then drive a shearing knife 213 to move, and then under the action of the linkage component 4, drive the other shearing knife 213 to move in the opposite direction to shear the branches. After the shearing is completed, the litchi fruit falls into the receiving barrel 611, slides downward along the inclined material guide barrel 1 612 and the material guide barrel 2 613, and finally falls into the material holding frame 712 for collection.

[0044] Combined with Figure 3 and attached Figure 4 As shown, the transmission assembly 3 includes a support seat 1 311 arranged on the mounting plate 112, a swing rod 312 is rotatably provided on the top surface of the support seat 1 311, a hinge seat 2 313 that can extend to the outside of the cylinder 217 is fixedly provided on the slide bar 216 corresponding to the end of the swing rod 312, and a groove body for the hinge seat 2 313 to slide is opened on the cylinder 217, and a support seat 2 314 is provided on the mounting plate 112 corresponding to the other end of the swing rod 312, a guide rod 315 is slidably provided on the support seat 2 314, and a hinge seat 3 316 is provided on the guide rod 315;

[0045] Both ends of the swing rod 312 are hinged with connecting seats 317, and the other ends of the connecting seats 317 at both ends are respectively hinged on the second hinge seat 313 and the third hinge seat 316, and the actuator 5 controls the sliding of the guide rod 315;

[0046] The linkage assembly 4 includes a gear 411 rotatably arranged on a fixed seat 211, and arc-shaped teeth 412 are meshed at both ends of the gear 411. The opposite ends of the two arc-shaped teeth 412 are respectively fixedly connected to the corresponding ends of the shearing knife 213, and an avoidance groove for the arc-shaped teeth 412 to swing is opened on the rear end of the shearing knife 213. A protective cover 413 is also provided on the mounting plate 112 at the corresponding position of the linkage assembly 4.

[0047] The working principle of the transmission component 3 and the linkage component 4 is that the guide rod 315 is driven by the execution component 5 to slide backward and adjust. Under the action of the hinged connecting seat 317, one end of the swing rod 312 is driven to swing backward, while the other end is driven to swing forward. Under the action of the connecting seat 317 and the second hinge seat 313, a sliding rod 216 is driven to slide forward and adjust, and then the front end of a shearing knife 213 is driven to swing forward. In the process of the above-mentioned shearing knife 213 swinging, the arc-shaped teeth 412 connected thereto are driven to swing backward, and then the gear 411 is driven to rotate. The rotation of the gear 411 drives the arc-shaped teeth 412 on the other side to swing forward, and at the same time drives the front end of the other shearing knife 213 to swing backward. Under the action of the relative swinging of the two shearing knives 213, the branches are cut.

[0048] Combined with Figure 4 , Attachment Figure 5 and attached Figure 6 As shown, the actuator 5 includes a support plate 511 arranged at the tail of the telescopic rod 1, and an L-shaped connecting frame 512 is provided on the support plate 511. A hand brake 513 is hinged at the vertical end of the connecting frame 512, and a brake wire 514 is fixedly provided on the horizontal end. The brake wire 514 is a prior art, and the outer diameter end of the brake wire 514 is fixedly connected to the horizontal end of the connecting frame 512. A fixing plate 515 for connecting the outer diameter of the other end of the brake wire 514 is provided on the support seat 314. A U-shaped frame 516 is hinged on the hand brake 513, and the two ends of the core wire in the brake wire 514 are respectively fixedly connected to the U-shaped frame 516 and the guide rod 315, and a clamping ring for limiting the brake wire 514 is provided on the telescopic rod 1.

[0049] The working principle of the actuator 5 is that the operator presses the hand brake 513 with his hand, and under the action of the hinged U-shaped frame 516, the core wire in the brake wire 514 is driven to move backward, and then the other end of the core wire is driven to move backward, so that the spring outside the core wire is compressed, and at the same time the guide rod 315 is driven to move backward and adjust. After releasing the external force on the hand brake 513, the compressed spring will automatically reset, thereby driving the core wire and the guide rod 315 to automatically reset.

[0050] Combined with Figure 3 , Attachment Figure 7 , Attachment Figure 8 , Attachment Fig. 9 and attached Fig.10As shown, the mounting plate 112 is provided with an arc groove 218 for mounting the arc seat 214, and both ends of the arc groove 218 are provided with clamping grooves 219, and both ends of the arc seat 214 are fixed with clamping blocks 220 adapted to the clamping grooves 219, and the bottom surface of the clamping groove 219 is provided with a mounting groove 221, and a positioning column 222 with a conical structure is fixedly provided on the bottom wall of the mounting groove 221, and a conical cylinder 223 that can extend into the mounting groove 221 and sleeve the positioning column 222 is fixedly provided on the bottom surface of the clamping block 220, the inner diameter of the conical cylinder 223 is smaller than the outer diameter of the positioning column 222, and a plurality of notches 224 are provided on the conical cylinder 223 along the circumferential direction, and grabbing grooves 225 are provided on the end surfaces on both sides of the arc seat 214.

[0051] The disassembly and connection principle of the arc seat 214 is to place the arc seat 214 into the arc groove 218, and install and connect it with the cooperation of the card grooves 219 and the card blocks 220 at both ends. During the connection process, the conical tube 223 is sleeved on the corresponding positioning column 222. Since the matching surfaces of the conical tube 223 and the positioning column 222 are conical structures, the conical tube 223 can be driven to expand under the action of the notch 224, so that the conical tube 223 is tightly connected to the positioning column 222, thereby ensuring the stability of the arc seat 214 after connection.

[0052] Combined with Figure 7 and attached Figure 8 As shown, an arc-shaped placement groove 614 for the mounting plate 112 to extend into is fixedly provided on the rear end of the top surface of the material receiving barrel 611, and both ends of the arc-shaped placement groove 614 are hinged with arc-shaped positioning seats 615 adapted to the mounting plate 112, and the two arc-shaped positioning seats 615 are detachably connected to the two ends of the mounting seat 111, and matching docking seats 617 are fixedly provided at the ends of the arc-shaped positioning seats 615 and the mounting seat 111, and a fastening screw 618 is passed through one docking seat 617, and an internal threaded hole matching the fastening screw 618 is opened on the other docking seat 617.

[0053] The disassembly and connection principle of the material receiving barrel 611 and the mounting plate 112 is as follows: first, the arc-shaped positioning seats 615 at both ends are swung back and forth to adjust, then the mounting plate 112 is extended into the arc-shaped placement groove 614, and then the arc-shaped positioning seats 615 at both ends are swung back and forth relative to each other, and finally, the two docking seats 617 are fixedly connected by the cooperation of the fastening screw 618 and the internal threaded hole, and the material receiving barrel 611 is connected to the mounting plate 112 at the same time.

[0054] The above-mentioned detachable connection between the arc seat 214 and the material receiving barrel 611 is to enable the present device to meet the operation of pruning the branches of trees. When shearing-type pruning is performed on the branches of trees, the material receiving barrel 611, the material guide barrel 1 612 and the material guide barrel 2 613 are first removed, and then the arc seat 214 is removed. When pruning the branches, the telescopic rod 1 is moved to move the branches to be sheared from the arc groove 218 into the two shear knives 213, and the movement of the two shear knives 213 is controlled to shear the branches, thereby improving the scope of use of the present device.

[0055] When the present invention is implemented, the operator first carries the material holding frame 712 on the side of the body through the oblique shoulder strap 711, operates the telescopic rod 1 to cover the left end of the mounting plate 112 with the litchi fruit, and then moves to the left, driving the telescopic rod 1 and the shearing knife 213 to move to the left, so that the branches above the litchi fruit are located between the two shearing knives 213, and then controls the hand brake 513 to perform a pressing action, and drives the transmission assembly 3 to act under the action of the brake line 514, and then drives a sliding rod 216 to slide , and then drives a shearing knife 213 to move, and then under the action of the linkage component 4, drives another shearing knife 213 to move in the opposite direction to shear the branches. After the shearing is completed, the litchi fruit falls into the receiving barrel 611, slides downward along the inclined material guide barrel 1 612 and the material guide barrel 2 613, and finally falls into the material holding frame 712 for collection. This not only increases the efficiency of picking litchi fruits, but also avoids the frequent adjustment of the telescopic rod 1 during the picking process, thereby reducing the labor intensity of the operator.

[0056] The present invention and its embodiments are described above, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and do not deviate from the purpose of the invention, they can creatively design a structure and embodiment similar to the technical solution, which should fall within the protection scope of the present invention.
