A rotary conveyor type pineapple stem and leaf whole plant harvester

Abstract

The invention discloses a rotary conveying type pineapple stem and leaf whole plant harvester, and relates to the technical field of pineapple harvesting. The inner side of the bottom plate is rotatably connected with a rolling component, and the top of the bottom plate is fixedly connected with a bracket. The invention provides a collecting component. When the pineapple moves on the conveyor belt, the buffer mechanism abuts against the top of the pineapple, so that self-adjustment can be performed according to the height of different pineapples, so as to avoid unnecessary cutting of the pineapple when the pineapple and the pineapple stem and leaf are cut. The cut pineapple stem and leaf are rotary conveyed and enter into a collecting shell through a feed port. The connecting shaft drives a rotating plate to rotate in the inner cavity of the collecting shell at the same time. When the rotating plate rotates following the connecting shaft, the sliding rod slides in the bottom of the rotating plate through the action of centrifugal force, so as to avoid the phenomenon that the pineapple stem and leaf that are rotary conveyed and enter into the collecting shell are accumulated in the inner cavity of the collecting shell.

Description

Technical Field

[0001] The invention relates to the technical field of pineapple harvesting, in particular to a rotary conveying type pineapple stem and leaf whole-plant harvester. Background Art

[0002] Because pineapple leaves are sharp and hard, with serrated edges, farmers need to wear protective clothing and eye protection when picking pineapples to prevent them from cutting themselves. During the picking process, farmers use knives to cut the pineapples from the plants and place them in baskets carried on their backs. The heavy baskets and the thorny pineapple fields are a significant drain on farmers' energy. This manual method of harvesting pineapples is inefficient, labor-intensive, and time-consuming. Harvesting costs account for approximately 40% of the total cost of pineapple cultivation. Clearly, vigorously developing mechanized pineapple harvesting is crucial for increasing farmers' incomes, improving the competitiveness of agricultural products, supporting labor transfer, and achieving agricultural modernization.

[0003] After being picked, a section of stems and leaves will still remain on the pineapple fruit, which still needs to be processed again, thereby increasing the cost of picking the pineapple fruit and making it difficult to improve the efficiency of automatic pineapple collection.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention provides a collecting component. When the pineapple moves along the conveyor belt, the buffer mechanism is used to counteract the top of the pineapple, so that it can self-adjust according to the height of different pineapples, thereby avoiding unnecessary cutting of the pineapple when cutting the pineapple and the pineapple stems and leaves. By turning on the first motor, the output end of the first motor drives the feeding mechanism to rotate in the round shell through the connecting shaft, so that the cut pineapple stems and leaves are circumferentially conveyed through the feed port into the collecting shell.

When the rotating plate rotates following the connecting shaft, the centrifugal force causes the slide bar to slide at the bottom of the rotating plate, thereby swinging the stems and leaves entering the collecting shell to the side away from the connecting shaft, thereby avoiding the phenomenon that the pineapple stems and leaves circumferentially conveyed into the collecting shell are accumulated in the inner cavity of the collecting shell, thereby interfering with the normal conveying and collecting work.

[0016] 2. The present invention provides a feeding mechanism. When the output end of the first motor drives the rotating block to rotate through the connecting shaft, the cutter is driven to rotate in the round shell through the rotating block, thereby cutting the pineapple stems and leaves passing through the notch. At the same time, when the rotating block rotates in the round shell, the spiral blade is driven to rotate in the inner cavity of the round shell, so that the spiral blade drives the cut pineapple stems and leaves to be circlingly transported to the collecting shell, so that the pineapple stems and leaves enter the collecting shell through the feed port for collection.

[0017] 3. The present invention is provided with a buffer mechanism. When the conveyor belt drives the pineapple cut by the cutting frame and passes through the fixed block through the limiting clamping of the limiting mechanism, when the pineapple and the connecting plate are pressed against each other, the squeezing force generated by the pressing against each other by the pineapple and the connecting plate at different heights causes the connecting plate to drive the slider to move in the sliding groove, thereby avoiding unnecessary cutting of the pineapple when cutting the pineapple and the pineapple stems and leaves, thereby affecting the beauty of the pineapple itself. By opening a notch on the top of the connecting plate, the stems and leaves on the pineapple can be cut through the notch, and at the same time, it is convenient for the subsequent feeding mechanism to cut the pineapple stems and leaves.

[0018] 4. The present invention provides a harvesting component, and the cutting frame continuously squeezes and moves with the pineapple, so that the cutting frame cuts the pineapple, thereby separating the pineapple from the pineapple root. At the same time, the device continuously moves, and the second motor is turned on, and the output end of the second motor and the transmission mechanism drive the conveyor belt to rotate, so that the pineapple moves following the conveyor belt. At the same time, the limiting mechanism squeezes and limits the pineapple, so that the collecting component can separate and collect the pineapple and the pineapple stems and leaves. At the same time, the conveyor belt drives the pineapple to move continuously, so that the pineapple slides through the cutting frame at the other end, thereby facilitating the subsequent operator to collect the pineapple.

[0036] The buffer mechanism 53 includes a fixed block 531, the inner side of the fixed block 531 is fixedly connected to the side of the round shell 59, the side of the fixed block 531 is evenly provided with sliding grooves 532, the inner wall of the sliding groove 532 is fixedly connected with a sliding rod 533, the inner side of the fixed block 531 is slidably connected with a connecting plate 534, the side of the connecting plate 534 is in contact with the inner side of the fixed block 531, the side of the connecting plate 534 is fixedly connected with a slider 536, the side of the slider 536 is slidably connected to the inner wall of the sliding groove 532, a first spring 535 is sleeved on the sliding rod 533, the top of the first spring 535 is fixedly connected to the bottom of the slider 536, the bottom of the first spring 535 is fixedly connected to the inner wall of the sliding groove 532, and the top of the connecting plate 534 is provided with a notch 534. 37, a connecting hole 538 is provided on the side of the slider 536; when the conveyor belt 45 drives the pineapple cut by the cutting frame 42, it passes through the fixed block 531 through the limiting clamping of the limiting mechanism 46, and when the pineapple and the connecting plate 534 are offset, the squeezing force generated by the offsetting of the pineapple and the connecting plate 534 at different heights causes the connecting plate 534 to drive the slider 536 to move in the sliding groove 532, thereby avoiding unnecessary cutting of the pineapple when cutting the pineapple and the pineapple stems and leaves, thereby affecting the beauty of the pineapple itself, and by providing a notch 537 on the top of the connecting plate 534, the stems and leaves on the pineapple can be cut through the notch 537, and at the same time, it is convenient for the subsequent feeding mechanism 55 to cut the pineapple stems and leaves.

[0037] The harvesting part 4 includes a connecting frame 41, both sides of the connecting frame 41 are fixedly connected to the cutting frame 42, the side of the connecting frame 41 is fixedly connected to the second motor 43, the side of the connecting frame 41 is rotatably connected to the transmission mechanism 44, the output end of the second motor 43 is fixedly connected to the input end of the transmission mechanism 44, the inner side of the connecting frame 41 is rotatably connected to the transmission belt 45, the output end of the second motor 43 is rollingly connected to the inner side of the transmission belt 45, and both sides of the top of the connecting frame 41 are fixedly connected to the limiting mechanism 46; when the device follows the rolling part 2 to move on the pineapple field, the cutting frame 42 is continuously squeezed and moved with the pineapple, so that the cutting frame 4 2. The pineapple is cut to separate the pineapple from the pineapple root. At the same time, the device is continuously moved. By turning on the second motor 43, the output end of the second motor 43 and the transmission mechanism 44 drive the conveyor belt 45 to rotate, so that the pineapple moves along with the conveyor belt 45.

At the same time, when the pineapple is driven by the conveyor belt 45 to be offset against the auxiliary roller 466, the stretching action of the second spring 465 is simultaneously used to prevent the limiting plate 464 from driving the auxiliary roller 466 to exert excessive squeezing force on the pineapple, thereby causing squeezing damage to the pineapple.

[0039] Example 2: Use Figure 8-Figure 9 The rotary conveyor type pineapple stem and leaf whole plant harvester of the present invention is described as follows:

[0040] like Figure 8-Figure 9 The present invention shows a rotary conveying type pineapple stem and leaf whole plant harvester, based on the first embodiment;

[0041] The rolling component 2 includes an electric roller 21 and a mounting groove 22. The side of the electric roller 21 is rotatably connected to the inner side of the base plate 1. The mounting groove 22 is opened on the inner side of the base plate 1. The inner wall of the mounting groove 22 is fixedly connected with a contact mechanism 23. The top of the base plate 1 is fixedly connected with a connecting rod 24. When the device drives the base plate 1 to move in the pineapple field through the electric roller 21, in order to prevent the soil in the pineapple field from getting stuck on the side of the electric roller 21 and not being cleaned for a long time, thereby interfering with the normal rotation of the electric roller 21, a mounting groove 22 is opened on the inner side of the base plate 1. When the electric roller 21 rotates, the side of the electric roller 21 can be cleaned through the contact mechanism 23.

[0042] The contact mechanism 23 includes a contact shell 231, a side surface of the contact shell 231 is provided with a rotating groove 232, the inner wall of the rotating groove 232 is rotatably connected to a roller 233, and the side surface of the contact shell 231 is fixedly connected to an extrusion rod 234, and one end of the extrusion rod 234 away from the contact shell 231 is slidably connected to the inner wall of the mounting groove 22, and a third spring 235 is sleeved on the extrusion rod 234, one end of the third spring 235 is fixedly connected to the side surface of the contact shell 231, and the other end of the third spring 235 is fixedly connected to the inner wall of the mounting groove 22; when the electric roller 21 rotates, the electric roller 21 contacts the contact shell 231 when it rotates, so that the roller 233 contacts and rotates with the side surface of the electric roller 21, and a plurality of grooves are provided on the side surface of the roller 233, so that the roller 233 can rotate in contact with the side surface of the electric roller 21. When 233 contacts and rotates with the electric roller 21, the roller 233 can contact and clean the mud adhering to the side of the electric roller 21 and the stones stuck on the side of the electric roller 21. At the same time, the stones cleaned by the roller 233 can fall into the rotating groove 232, thereby preventing the cleaned stones from being stuck on the electric roller 21 when the electric roller 21 moves subsequently. When there is a lot of mud and impurities adhering to the electric roller 21, when the extrusion force of the mud and impurities and the roller 233 is too large, the telescopic rod 463 drives the contact shell 231 to move toward the installation groove 22. At the same time, the buffering stretching of the third spring 235 avoids the extrusion force of the electric roller 21 and the roller 233 from being too large when cleaning.

[0043] The specific workflow is as follows:

[0044] During operation, the machine is moved to the pineapple field through the rolling part 2, and the push bracket 3 is held and pushed to follow the device to harvest the pineapples on the pineapple field through the harvesting part 4. At the same time, the whole pineapple stems and leaves can be collected by opening the collecting part 5;

[0045] When the device follows the rolling component 2 to move on the pineapple ground, the cutting frame 42 is continuously squeezed and moved with the pineapple, so that the cutting frame 42 cuts the pineapple, thereby separating the pineapple from the pineapple root. At the same time, the device continues to move, and the second motor 43 is turned on. The output end of the second motor 43 and the transmission mechanism 44 drive the conveyor belt 45 to rotate, so that the pineapple moves following the drive of the conveyor belt 45. At the same time, the limiting mechanism 46 is squeezed and limited with the pineapple, so that the collecting component 5 can separate and collect the pineapple and the pineapple stems and leaves. At the same time, the pineapple is driven to move continuously by the conveyor belt 45, so that the pineapple slides through the cutting frame 42 at the other end, thereby facilitating the subsequent operator to collect the pineapple.

[0046] When the pineapple is moved by the conveyor belt 45, the limiting plate 464 drives the auxiliary roller 466 to contact and limit the side of the pineapple through the tension of the second spring 465, thereby facilitating the collecting component 5 to cut the pineapple stems and leaves. At the same time, when the pineapple is driven by the conveyor belt 45 to contact the auxiliary roller 466, the tension of the second spring 465 prevents the limiting plate 464 from driving the auxiliary roller 466 to squeeze the pineapple too much, thereby preventing the pineapple from being damaged by squeezing.

[0047] When the pineapple moves along the conveyor belt 45, the buffer mechanism 53 is pressed against the top of the pineapple, so that it can be self-adjusted according to the height of different pineapples, avoiding unnecessary cutting of the pineapple when cutting the pineapple and the pineapple stems and leaves. By turning on the first motor 52, the output end of the first motor 52 drives the feeding mechanism 55 to rotate in the round shell 59 through the connecting shaft 58, so that the cut pineapple stems and leaves are transported in a circular manner through the feed port 56 into the collecting shell 51, and at the same time, the output end of the first motor 52 drives the connecting shaft 58 to rotate in the collecting shell 51. When the collecting housing 51 rotates, the connecting shaft 58 simultaneously drives the rotating plate 510 to rotate in the inner cavity of the collecting housing 51. When the rotating plate 510 rotates following the connecting shaft 58, the centrifugal force causes the sliding rod 54 to slide at the bottom of the rotating plate 510, thereby swinging the stems and leaves entering the collecting housing 51 to the side away from the connecting shaft 58, thereby preventing the pineapple stems and leaves that are circumferentially transported into the collecting housing 51 from piling up in the inner cavity of the collecting housing 51, thereby interfering with the normal transport and collection work.

[0048] When the conveyor belt 45 drives the pineapple cut by the cutting frame 42 and passes through the fixed block 531 through the limiting clamping of the limiting mechanism 46, when the pineapple and the connecting plate 534 are offset, the squeezing force caused by the pineapple and the connecting plate 534 at different heights causes the connecting plate 534 to drive the slider 536 to move in the sliding groove 532, thereby avoiding unnecessary cutting of the pineapple when cutting the pineapple and the pineapple stems and leaves, thereby affecting the beauty of the pineapple itself. By providing a notch 537 on the top of the connecting plate 534, the stems and leaves on the pineapple can be cut through the notch 537, and at the same time, it is convenient for the subsequent feeding mechanism 55 to cut the pineapple stems and leaves;

[0049] When the output end of the first motor 52 drives the rotating block 551 to rotate through the connecting shaft 58, the rotating block 551 drives the cutter 553 to rotate in the circular shell 59, thereby cutting the pineapple stems and leaves passing through the notch 537. At the same time, when the rotating block 551 rotates in the circular shell 59, it drives the spiral blade 552 to rotate in the inner cavity of the circular shell 59, so that the spiral blade 552 drives the cut pineapple stems and leaves to be circlingly transported to the collecting shell 51, so that the pineapple stems and leaves enter the collecting shell 51 through the feed port 56 for collection.

[0050] The device drives the bottom plate 1 to move in the pineapple field through the electric roller 21. In order to prevent the mud in the pineapple field from getting stuck on the side of the electric roller 21 and not being cleaned for a long time, thereby interfering with the normal rotation of the electric roller 21, a mounting groove 22 is opened on the inner side of the bottom plate 1. When the electric roller 21 rotates, the contact mechanism 23 can clean the side of the electric roller 21.

[0051] When the electric roller 21 rotates, the electric roller 21 contacts the contact housing 231, so that the roller 233 contacts and rotates with the side of the electric roller 21. By opening a plurality of grooves on the side of the roller 233, the roller 233 can clean the mud adhering to the side of the electric roller 21 and the stones stuck on the side of the electric roller 21 when the roller 233 contacts and rotates with the electric roller 21. At the same time, the stones cleaned by the roller 233 can fall into the rotating groove 233. 2, thereby preventing the stones that have been cleaned from being stuck on the electric roller 21 when the electric roller 21 moves subsequently. When there is a lot of dirt and impurities adhering to the electric roller 21, and when the extrusion force of the dirt and impurities and the roller 233 is too large, the contact housing 231 is driven to move toward the mounting groove 22 by the telescopic rod 463, and at the same time, the buffering stretching of the third spring 235 is used to prevent the extrusion force between the electric roller 21 and the roller 233 from being too large during the cleaning contact, thereby causing extrusion damage to the electric roller 21 and the roller 233.
