Description

Technical Field

[0001] This utility model relates to the technical field of orchard picking equipment, specifically a traction-type orchard picking operation platform. Background Technology

[0002] Orchard harvesting equipment can greatly improve work efficiency and reduce manual labor intensity. Different fruits and harvesting environments require different equipment. Common orchard harvesting equipment includes manual tools and mechanized equipment.

[0003] Referring to patent document CN210406240U, "A Harvesting Platform Type of Same-Track Vehicle" (hereinafter referred to as the Same-Track Platform), its lifting platform has a basket with a fruit bag loading device. During harvesting, the tensioner pulls up the inner and outer fruit bags. The farmer raises the basket to the harvesting height using a foot switch and extends the basket to the harvesting position using a knob switch. The harvested fruit is placed in the inner fruit bag. After the basket is full, the basket retracts and the platform lowers to its lowest point. The inner and outer tensioners alternately loosen, and the apples creep down until the outer fruit bag touches the bottom of the basket (or the top of the fruit in the basket). The farmer then slowly raises the basket using a foot switch, and the fruit enters the basket in a funnel shape. At this time, the degree of coordination between the farmers on the two baskets is very important, as it relates to the commercial indicators of the apples. Field harvesting practice has proven that after training, farmers can reduce the apple bruising rate to a minimum (≤5%) by harvesting synchronously. By repeating this operation, a new mode of fruit harvesting with a lifting platform and double baskets can be realized.

[0004] Firstly, with the towable picking platform, after the fruit baskets are full, a tractor is needed to tow the platform to the fruit warehouse or storage yard for unloading. The fruit farmers then need to enter another set of baskets on the same platform to carry out the picking operation again. This frequent up and down from the machine is inconvenient for the fruit farmers and also poses certain safety hazards. In particular, the fruit baskets cannot be unloaded directly between the picking rows, which has a significant impact on the picking efficiency.

[0005] Based on this, this utility model designs a towable orchard harvesting platform to solve the problem. Utility Model Content

The telescopic ends of the two first hydraulic cylinders 302 are rotatably mounted on the inner walls of the two pedals 301 by two hinges respectively. The first hydraulic cylinders 302 can push the pedals 301 to move along the slides 303, thereby unfolding the pedals 301 so that the pedals 301 can support the workers.

[0030] Please see Figure 4 The lifting platform mechanism 4 includes two lifting guide rails 401 mounted on the upper surface of the frame 102. A lifting cylinder 402 is fixedly mounted on the upper surface of the bottom end of each lifting guide rail 401. Telescopic devices 403 are slidably mounted on the inner walls of the two lifting guide rails 401 via two connectors. The telescopic device 403 consists of a frame, a sliding rail slider, and a mounting plate. Two baskets 404 are fixedly mounted on the control end of the telescopic device 403. A fruit bag loading device 405 is mounted at a height on the right side of each basket 404. The top of the two lifting cylinders 402... A connecting frame 406 is fixedly installed together. The control end of the connecting frame 406 is fixedly installed with the telescopic device 403. By activating the lifting cylinder 402, the connecting frame 406 can control the telescopic device 403 to move up and down along the lifting guide rail 401, and the telescopic device 403 can drive the basket 404 to move up and down, so that the pickers can pick water pipes at different heights. The fruit bag loading device 405 can put the bottom of the fruit bag in, and the entrance of the fruit bag can be bound to the top of the fruit bag loading device 405, so that the pickers do not need to carry the fruit bag by hand.

[0031] Please see Figure 5 The roller conveyor mechanism 5 includes a left plate 501 and a right plate 502 mounted on the upper surface of the frame 102. A set of first polyurethane rollers 503 are rotatably mounted on the inner wall of the left plate 501 and the inner wall of the right plate 502. Two support legs 504 are fixedly mounted on the bottom surface of the left plate 501 and the bottom surface of the right plate 502. The bottom surface of each support leg 504 is fixedly mounted to the upper surface of the frame 102. This roller conveyor mechanism 5 is a non-powered conveyor. In order to ensure that the fruit baskets filled with fruit slide smoothly without bumps or shaking when sliding on it, the first polyurethane rollers 503 are arranged in an alternating and overlapping manner.

[0032] Please see Figure 6The unloading mechanism 6 includes a conveyor frame 601 located on the left side of the frame 102. Two roller mounting side plates 602 are fixedly mounted on the upper surface of the conveyor frame 601. A set of second polyurethane rollers 603 are rotatably mounted on the inner wall of each roller mounting side plate 602. Two crank arms 604 are rotatably mounted on the bottom surface of the conveyor frame 601 via two hinges. The right end of each crank arm 604 is rotatably mounted to the left side of the frame 102 via two hinges. Two first swing cylinders 605 and... are fixedly mounted on the left side of the frame 102. The telescopic ends of the two second swing cylinders 606 and the two first swing cylinders 605 are fixedly installed on the bottom surface of the conveyor frame 601 through two hinges. By controlling the first swing cylinders 605 and the two second swing cylinders 606 in sequence, the conveyor frame 601 can be raised and lowered, so that the fruit basket can slide on the second polyurethane rollers 603. At the same time, the fruit basket is unloaded from the landing platform mechanism 3 onto the ground as it is raised and lowered.

[0033] Please see Figure 6 Two stoppers 607 are rotatably installed on the left end of the conveyor frame 601. The tail stopper 607 mainly plays a blocking role when the fruit basket is raised and lowered. When one end of the conveyor frame 601 lands, the tail tractor unfolds and releases, pulling the tractor forward to separate the fruit basket from the roller conveyor and land safely and smoothly.

[0034] Please see Figure 7 The storage frame mechanism 7 includes a base 701 mounted on the upper surface of the frame 102. Two sets of uprights 703 are fixedly mounted on the upper surface of the base 701. Two sets of bearing plates 702 are rotatably mounted on the side of the two sets of uprights 703 that are close to each other. The storage frame mechanism 7 is divided into three layers. When it is necessary to take out the fruit basket, the limiting bolt of the first layer is opened, the bottom fruit basket is pulled out, and then the hinged bearing plate 702 of the upper layer is opened to allow the fruit basket to slide down to the first layer, and so on.

[0035] The implementation principle of the towed orchard harvesting platform in this application embodiment is as follows: During use, the towing device 2 pulls the vehicle body mechanism 1 to move it into the orchard. Workers place the harvesting basket on the vehicle body mechanism 1, and then the harvester stands inside the basket 404. The lifting cylinder 402 is activated, causing it to push the connecting frame 406 upwards. The connecting frame 406 then drives the telescopic device 403 upwards along the lifting guide rail 401, causing the basket 404 and the fruit bag loading device 405 to move upwards, allowing workers to harvest fruit. The harvester then places the fruit bag over the fruit bag loading device 405 and secures it to prevent it from falling off. The harvested fruit is placed inside the fruit bag for storage. Once the fruit bag is full, it is emptied into the harvesting area. Inside the frame, after multiple picking frames are filled, the picking frames are pushed, causing them to move onto the unloading mechanism 6 via the first polyurethane roller 503. Then, the first swing cylinder 605 and the second swing cylinder 606 are controlled to operate sequentially, controlling the conveyor frame 601 to move downwards, allowing the conveyor frame 601 to carry the picking frames down. After the frames have fallen, the stopper 607 is controlled to rotate, allowing the picking frames to move downwards via the second polyurethane roller 603, completing the unloading operation of the picking frames. When picking lower fruits, the first cylinder 302 can be activated, causing it to push the pedal 301 along the slide 303, allowing the pedals 301 to move away from each other and unfold, so that workers can step on the pedals 301 to pick the lower fruits.
