Description

Technical Field

[0001] The invention relates to the field of navel orange picking equipment, and in particular to an all-terrain cart specially used for navel orange picking. Background Art

[0002] For some navel orange orchards located in areas with relatively small ground undulations and relatively flat ground in mountainous areas, in order to improve the picking efficiency, there is a picking form in which multiple pickers use an all-terrain cart to stop in different areas of the navel orange plantation. After the pickers pick the navel oranges around the all-terrain cart, they transport them back to the cart, and then return to the navel orange trees empty-handed to pick again. After all the navel orange trees within a certain range around the cart are picked, the cart is moved to another area. The time consumed includes a lot of time for the pickers to travel back and forth between the cart and the navel orange trees, which affects the picking efficiency of the navel oranges. When the cart bed is full of a large number of navel oranges and is moving in a navel orange orchard with uneven ground, it is bound to produce severe bumps, which can easily cause the loaded navel oranges to be shaken to the ground, causing some of the fallen navel oranges to be broken and damaged, and need to be picked up and loaded again. Summary of the invention

[0003] In order to overcome the disadvantages that the pickers pick the navel oranges around the all-terrain cart, transport them back to the cart, and then return to the navel orange tree empty-handed to pick them again, which affects the picking efficiency of the navel oranges and also causes the navel oranges to fall to the ground and be damaged, the present invention provides an all-terrain cart specifically for picking navel oranges.

[0004] The technical solution is: an all-terrain cart for picking navel oranges, comprising a cart, moving wheels, a support frame, a rotating rod, a multi-stage telescopic rod, an elastic protective net, a fixing cylinder, a locking assembly, a conveying hose and a quick plug-in assembly; the cart is provided with at least two moving wheels; the cart is provided with at least two supporting frames; each of the four corners of the cart bucket of the cart is rotatably connected to a rotating rod, and the rotating direction of the rotating rod is set to be toward the center direction of the cart bucket of the cart; a ball head bearing is provided at the upper end of the rotating rod, and a multi-stage telescopic rod is commonly connected between the ball head bearings at the upper ends of the two rotating rods.

[0006] Furthermore, the trolley is provided with a plurality of insertion rods; and the feed hopper is provided with a socket structure adapted to the insertion rods.

[0007] Furthermore, the quick plug-in assembly is composed of a permanent magnet and a terminal; the permanent magnet is fixedly connected to the fixed cylinder; the outlet end of the conveying hose is connected to the terminal, and the terminal is made of ferromagnetic material.

[0008] Furthermore, a transverse slider is slidably connected inside the cart bucket; a tension spring is fixedly connected between the transverse slider and the cart bucket; an arc tube is fixedly connected to the transverse slider; a fixed thread structure is provided at the inlet end of the arc tube; and a movable thread structure that matches the fixed thread structure of the arc tube is provided at the outlet end of the end head.

[0017] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings. Example 1

[0018] An all-terrain cart for picking navel oranges, such as Figure 1-Figure 6As shown, the trolley 11 includes a moving wheel 12, a support frame 13, a rotating rod 21, a multi-stage telescopic rod 22, an elastic protective net 23, a fixing cylinder 24, a locking assembly, a delivery hose 3 and a quick plug assembly; the trolley 11 is provided with two moving wheels 12; the trolley 11 is provided with two supporting frames 13; each of the four corners of the bucket of the trolley 11 is rotatably connected with a rotating rod 21; the rotation direction of the four rotating rods 21 is set to be toward the center direction of the bucket of the trolley 11; each upper end of each rotating rod 21 is provided with a ball head bearing, and each front A multi-stage telescopic rod 22 is connected between the ball bearings at the upper ends of the rear two rotating rods 21. The multi-stage telescopic rod 22 is composed of a fixed rod component and a telescopic rod component, wherein the fixed rod component of the multi-stage telescopic rod 22 and the telescopic rod component farthest from the fixed rod component are respectively connected to corresponding ball bearings; a locking assembly is commonly connected between the fixed rod component of each multi-stage telescopic rod 22 and the telescopic rod component farthest from the fixed rod component on the same multi-stage telescopic rod 22; a circle of elastic protective net 23 is commonly fixed between the four rotating rods 21, and the bucket of the trolley 11 is locked by the elastic net 23. , the rotating rod 21 and the elastic protective net 23 together form a loading frame; a fixed tube 24 is fixedly connected to the fixed rod part of any multi-stage telescopic rod 22; a conveying hose 3 slides in the fixed tube 24; a quick plug-in assembly is commonly connected between the outlet end of the conveying hose 3 and the fixed tube 24; a feed hopper 31 is connected to the inlet end of the conveying hose 3; one end of the conveying hose 3 close to the feed hopper 31 is set as a telescopic tube structure, and the telescopic tube structure is a foldable and stretchable corrugated structure, and the picker can lengthen the conveying hose 3 by stretching the telescopic tube structure of the conveying hose 3. 3, the pickers can shorten the length of the conveying hose 3 by contracting the telescopic tube structure of the conveying hose 3, and the shortened length of the conveying hose 3 is convenient for it to be stored on the cart 11; the cart 11 is provided with a plurality of insertion rods 14; the feed hopper 31 is provided with two sockets 310 structures adapted to the insertion rods 14, and during non-picking work, the pickers can complete the fixing of the feed hopper 31 on the conveying hose 3 by plugging the feed hopper 31 on the insertion rod 14 of the cart 11 through the sockets 310 structures, thereby preventing the conveying hose 3 from being dragged on the ground.

[0019] like Figure 4 As shown, the locking assembly consists of an L-shaped clamping rod 26 and a torsion spring 27; the L-shaped clamping rod 26 is rotatably connected to the fixed rod part of the multi-stage telescopic rod 22; two torsion springs 27 are fixedly connected between the L-shaped clamping rod 26 and the corresponding fixed rod part of the multi-stage telescopic rod 22; the clamping end of the L-shaped clamping rod 26 is initially inserted into the clamping groove corresponding to the surface of the telescopic rod part of the multi-stage telescopic rod 22 farthest from the fixed rod part. In this state, the telescopic rod part of the multi-stage telescopic rod 22 is firmly locked by the clamping end of the L-shaped clamping rod 26 on the fixed rod part of the multi-stage telescopic rod 22, and the torsion spring 27 assists the L-shaped clamping rod 26 to make the locking effect more stable.

[0020] like Figure 3 and Figure 4 As shown, the quick plug-in assembly consists of a permanent magnet 25 and an end 32; the permanent magnet 25 is fixedly connected to the fixed cylinder 24; the outlet end of the conveying hose 3 is connected to the end 32, and the end 32 is a ferromagnetic material; the permanent magnet 25 generates a magnetic attraction to the end 32 of the stainless steel iron material, so that the end 32 is firmly magnetically attracted to the permanent magnet 25, and the picker only needs to pull the end 32 away from the permanent magnet 25 to quickly complete the separation of the two.

[0021] like Figure 2 and Figure 5 As shown, a transverse slider 4 is slidably connected in the bucket of the trolley 11; a light tension spring 41 is fixedly connected between the transverse slider 4 and the bucket of the trolley 11; an arc tube 42 is fixedly connected to the transverse slider 4, and the outlet end of the arc tube 42 is downwardly directed toward the bottom of the bucket of the trolley 11; a fixed thread structure is provided at the inlet end of the arc tube 42; the end head 32 is rotatably connected to the conveying hose 3; the outlet end of the end head 32 is provided with a movable thread structure that matches the fixed thread structure of the arc tube 42, and when the end head 32 is rotated and tightened on the fixed thread structure of the arc tube 42 through the movable thread structure, the end head 32 will be firmly fixed on the arc tube 42.

[0022] During the picking operation of the all-terrain cart specially used for picking navel oranges of the present invention, the picker first uses the moving wheels 12 to move the cart 11 along the forest path reserved between the rows of navel orange trees in the navel orange orchard to between multiple navel orange trees. By widening and enlarging the moving wheels 12, the cart 11 can be normally moved on the navel orange orchard road with a certain degree of ruggedness, so that the cart is more adaptable to the rugged road surface; the picker then lays the cart 11 flat, and the support frame 13 on the cart 11 is propped up on the ground, so that the cart 11 is parked between the multiple navel orange trees, and then the picker respectively pulls up the L-shaped clamping rods 26 on the two multi-stage telescopic rods 22 to extend the multi-stage telescopic rods 22, and then the picker pulls all the rotating rods 21 to flip to the side away from the cart 11, and at the same time, the rotating rods 21 on the front and rear sides respectively pull the fixed rod component and the telescopic rod component of the multi-stage telescopic rod 22 to expand in the direction away from each other, such as Figure 7 As shown, at this time, the four flipped-open rotating rods 21 jointly open the elastic protective net 23 to the four sides, so that the navel orange loading entrance area of ​​the loading frame composed of the cart 11, the rotating rods 21 and the elastic protective net 23 is increased, and the pickers can easily put the picked navel oranges into the loading frame when picking the navel oranges on the navel orange trees around the parking area of ​​the cart 11.

[0023] Combination Figure 2 and Figure 3It is understood that when picking navel oranges that are relatively far from the cart 11, one of the pickers pulls the end 32 of the conveying hose 3 off the permanent magnet 25 in advance, and tightens the end 32 of the conveying hose 3 on the fixed thread structure of the arc tube 42 through the movable thread structure, so that the end 32 is fixed on the arc tube 42, as shown in FIG. Figure 7 As shown, the picker then holds the conveying hose 3 and walks to the navel orange tree far away from the parking area of ​​the cart 11 to pick navel oranges. The conveying hose 3 is pulled outward along the fixed cylinder 24. At the same time, the conveying hose 3 pulls the transverse slider 4 to drive the arc tube 42 to move toward the fixed cylinder 24. The transverse slider 4 drives the light tension spring 41 to stretch. The picker puts the picked navel oranges into the conveying hose 3 through the feed hopper 31. As long as the inlet end of the conveying hose 3 is pulled upward to a height higher than the fixed cylinder 2, the navel oranges can be allowed to slide along the conveying hose 3 and the arc tube 42 into the cart of the cart 11 in turn, completing the long-distance transportation of the navel oranges. The pickers do not need to put the navel oranges picked from a distance into the loading frame and then return to the navel orange tree empty-handed, thus reducing the time spent on the road. When the pickers pull the conveying hose 3 to move to the navel orange tree farther away to pick the navel oranges, the conveying hose 3 will pull the transverse slider 4 to drive the arc tube 42 to move closer to the fixed cylinder 24. At this time, the navel oranges sliding down from the outlet end of the arc tube 42 will fall into the area on the side of the fixed cylinder 24 in the bucket of the cart 11, so that the pickers can change the position of the outlet as the pickers move while continuously pulling the conveying hose 3, and evenly load the navel oranges into various areas of the loading frame.

[0024] When other pickers working near the cart 11 observe that the loading height of navel oranges in the cart 11 is about to be flush with the height of the arc tube 42, but there are still navel oranges that can be picked near the pickers picking at a distance, they remove the end 32 from the arc tube 42 and magnetically fix the end 32 to the permanent magnet 25 of the fixed cylinder 24 again, so that the conveying hose 3 can be pulled out of the fixed cylinder 24 to a longer length, and the pickers picking at a distance can also pull the telescopic end of the conveying hose 3 to the navel oranges that are farther away than before. When picking navel oranges, after the pickers at a distance put the picked navel oranges into the conveying hose 3, it is possible that the conveying hose 3 has been sent out but the pickers at a distance have not moved further. At this time, the conveying hose 3 has a certain amount of movable margin. At this time, when the large navel oranges slide toward the trolley 11 in the conveying hose 3, there is a very low probability that the conveying hose 3 will fall and bend due to the downward pressure of the navel oranges. When the falling and bending area appears near the fixed cylinder 24, the navel oranges Further sliding toward the fixed cylinder 24 becomes "uphill", which may not be successful due to insufficient power, and eventually causes the navel oranges to remain in the conveying hose 3. At this time, the picker near the trolley 11 needs to manually lift the conveying hose 3 to send the remaining navel oranges into the trolley 11. The navel oranges directly fall along the conveying hose 3 onto the elastic protective net 23, and roll down and accumulate between the bucket of the trolley 11 and the elastic protective net 23. Then the picker finishes picking near the trolley 11 and starts to move the navel oranges that are subsequently sent to the trolley 11 to the The pickers who were originally picking near the cart 11 no longer pick the oranges, but adjusting the shape of the orange pile to avoid concentrated accumulation is also a necessary step in the entire picking process, so the placement work is also a necessary work step. If the pickers who are picking at a distance from the cart 11 are chosen to handle the above events, the pickers still have to return to the cart 11 first, which results in unnecessary time consumption.

[0025] After finishing the picking work, the picker needs to first reset the rotating rod 21 to the center of the cart 11. Figure 1 As shown, the four flip-over and reset rotating rods 21 jointly drive the elastic protective net 23 to be retracted toward the center of the bucket of the cart 11, so that the elastic protective net 23 is retracted to fit the surface of the navel oranges filled in the loading frame, and at the same time, the rotating rods 21 on the front and rear sides respectively push the fixed rod component and the telescopic rod component of the multi-stage telescopic rod 22 to retract and reset in the direction of approaching each other, and then the picker inserts the card end of the L-shaped clamping rod 26 back into the card slot of the telescopic rod component of the multi-stage telescopic rod 22, so that the telescopic rod component of the multi-stage telescopic rod 22 is firmly locked by the card end of the L-shaped clamping rod 26, so that when the picker pushes the cart 11 to move, even if the cart 11 is violently bumpy, the elastic protective net 23 between the four rotating rods 21 can limit the navel orange pile and provide anti-fall protection. Example 2

[0026] The difference between this embodiment and embodiment 1 is that Figure 1-Figure 6 As shown, each of the four corners of the trolley 11 is fixed with a support rod 28 for supporting and unfolding the rotating rod 21 on the same side. A magnet that can magnetically attract the rotating rod 21 is embedded in the support rod 28. The rotating rod 21 is made of ferromagnetic material. The magnetic attraction generated by the magnet is greater than the restoring elastic force generated by the elastic protective net 23 after being stretched and unfolded. The surface of the support rod 28 is covered with a layer of elastic rubber material. When the rotating rod 21 is turned outward as shown in FIG. Figure 7 In the unfolded state shown, the rotating rod 21 is adsorbed on the corresponding supporting clamp rod 28, and the supporting clamp rod 28 restricts the rotating rod 21 to prevent the rotating rod 21 from being unable to unfold normally under the elastic force of the elastic protective net 23; generally, the picker manually unfolds the rotating rod 21, and when the hand feels the magnetic attraction of the supporting clamp rod 28 on the rotating rod 21, he directly lets go, and the supporting clamp rod 28 is automatically adsorbed on the rotating rod 21. For strong magnetic properties such as neodymium iron boron magnets, in fact, the last action of the rotating rod 21 is closer to directly hitting the surface of the supporting clamp rod 28. If it happens too many times, it is easy to cause local deformation of the rotating rod 21 and other problems. Therefore, by covering it with a layer of rubber skin, the hitting effect can be slowed down and the rotating rod 21 can be protected without affecting the magnetic attraction and fixing function. Example 3

[0027] A buffer sponge is provided at the bottom of the cargo box of the cart 11; the navel oranges sliding down from the outlet end of the arc tube 42 and falling into the cargo box of the cart 11 will be immediately supported by the buffer sponge with elastic buffering properties to prevent the navel oranges from falling directly into the cargo box of the cart 11 and being damaged, thereby providing protection for the picked navel oranges.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
