Description

Technical Field

[0001] This invention relates to the field of palm fruit harvesting technology, and in particular to a palm fruit harvesting machine with a telescopic lifting arm. Background Technology

[0002] Palm fruit, also known as oil palm fruit, grows on large fruit clusters of palm trees. Each fruit cluster contains approximately 2,000 palm fruits. When harvesting palm fruit, the large fruit clusters are usually cut directly from the palm tree and then sent to a processing plant for processing.

[0003] The invention patent CN1159897 Rotary Axis 52 discloses a mechanically adjustable fruit picking robot and its picking method, which includes a walking mechanism and a picking mechanism. The picking mechanism includes a lifting adjustment unit and a positioning and cutting unit set on the lifting adjustment unit. The lifting adjustment unit is used to drive the positioning and cutting unit to rise and approach the picking object. The positioning and cutting unit is used to position and cut the picking object. The walking mechanism is a tracked transport vehicle, which includes a tracked walking device, a wireless navigation control device and a hydraulic lifting and rotating device set on the tracked walking device.

[0004] The aforementioned harvesting robots and existing technologies for harvesting palm fruit bunches both involve cutting the palm fruit bunches at the base. The palm fruit bunches with the cut bases fall directly from the palm tree and collide with the ground. During this process, a small number of palm fruits fall from the palm fruit bunches. In order to save labor, the fallen palm fruits are usually not collected again, resulting in significant waste.

[0005] In addition, since the palm fruit clusters are distributed around the palm tree trunk, the fallen palm fruit clusters will be scattered in a certain area around the palm tree. When picking the fallen palm fruit clusters to load onto the truck, the pickers need to frequently go back and forth between the location where the palm fruit clusters fell and the location of the vehicle, which is not only inefficient but also too labor-intensive.

[0006] Therefore, it is necessary to invent a palm fruit harvesting machine with a telescopic lifting arm to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a palm fruit harvester with a telescopic lifting arm, which can directly transport the cut palm fruit bunches into the truck bed. This eliminates the need for frequent manual back-and-forth loading and avoids the waste caused by palm fruit bunches falling directly to the ground. It increases palm fruit yield while reducing harvesting costs and improving loading efficiency. This addresses the problem mentioned in the background art where palm fruit bunches cut at the root fall directly from the palm tree and collide with the ground. During this process, a small number of palm fruits fall from the bunches, and to save labor, these fallen fruits are usually not collected again, resulting in significant waste. Furthermore, since the palm fruit bunches are distributed around the palm tree trunk, after falling, they are scattered in a certain area around the tree. When harvesters collect and load the fallen bunches, they need to frequently travel back and forth between the location where the bunches fell and the vehicle, resulting in low loading efficiency and excessive labor consumption.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a palm fruit harvester with a telescopic lifting arm, comprising a telescopic lifting arm, an adjustment component fixedly connected to the top of the telescopic lifting arm, a palm fruit bunch guiding mechanism fixedly disposed on the right side of the adjustment component, an insertion cutting mechanism and a plurality of evenly distributed blade blocking mechanisms disposed on the inner side of the top opening of the palm fruit bunch guiding mechanism, and a fixing component disposed at the bottom right side of the palm fruit bunch guiding mechanism;

[0009] The inlet ring frame of the palm fruit bunch guiding mechanism is fixedly installed on the right side of the movable plate. A rubber corrugated pipe is fixedly connected to the bottom of the inlet ring frame, and an outlet ring frame is fixedly installed at the bottom of the rubber corrugated pipe.

[0010] The C-shaped plate in the insertion cutting mechanism is fixedly installed inside the right side of the entrance ring frame. A screw is rotatably nested inside the C-shaped plate via a bearing. A motor connected to the screw is fixedly installed at the bottom of the C-shaped plate. The screw is driven and sleeved on the outside of the first lifting plate. The first lifting plate slides against the inner wall of the C-shaped plate. A cutter is fixedly installed on the top right side of the first lifting plate. A buffer spring is fixedly connected to the top center of the first lifting plate. A second lifting plate is fixedly installed at the top of the buffer spring. The second lifting plate slides vertically against the outside of the cutter and slides against the inner wall of the C-shaped plate. The second lifting plate slides against the outside of the screw. A fixing rod is fixedly installed on the top left side of the second lifting plate.

[0011] Preferably, the insertion and cutting mechanism further includes a filling block, which is fixedly disposed on the left side of the C-shaped plate.

[0012] Preferably, the top left side of the C-shaped plate has a first clearance channel for the passage of the fixed insertion rod, and the top right side of the C-shaped plate has a second clearance channel for the passage of the cutter.

[0013] Preferably, the adjustment assembly includes a back plate, a fixing plate, a fixing block, and a fixing pin;

[0014] Two fixing plates are provided, both of which are fixedly installed on the left side of the back plate. The fixing block is slidably inserted between the two fixing plates and fixedly installed at the end of the telescopic lifting arm. Both the fixing plates and the fixing block are provided with connecting holes, and the fixing pin is inserted into the inside of the connecting holes.

[0015] Preferably, the adjusting assembly further includes a movable plate and a first adjusting hydraulic cylinder;

[0016] The movable plate is movably connected to the right side of the back plate via a pin. One end of the first adjusting hydraulic cylinder is movably connected to the back plate via a pin, and the other end is movably connected to the movable plate via a pin.

[0017] Preferably, the blade blocking mechanism includes a fixed frame, a rotating shaft, a blocking plate, and a return torsion spring;

[0018] The fixed frame is fixedly installed inside the entrance ring frame. The rotating shaft is rotatably nested inside the fixed frame via a bearing. The blocking plate is fixedly sleeved on the middle of the outer side of the rotating shaft. There are two reset torsion springs, which are respectively sleeved on both ends of the outer side of the rotating shaft. Each reset torsion spring is fixedly connected between the inner wall of the fixed frame and the blocking plate.

[0019] Preferably, the fixing assembly includes an L-shaped plate, a clamping plate, and a locking bolt;

[0020] The L-shaped plate is fixedly installed at the bottom right side of the outlet ring frame, the clamping plate is fixedly installed at the bottom of the L-shaped plate, and the locking bolt is installed through the right side of the L-shaped plate and threadedly connected to the L-shaped plate.

[0021] Preferably, it also includes a walking device, the top of which is provided with a steering device for turning the telescopic lifting arm. The telescopic lifting arm is movably connected to the top of the steering device via a pin. A second adjusting hydraulic cylinder for adjusting the tilt of the telescopic lifting arm is also movably connected between the telescopic lifting arm and the steering device.

[0022] The technical effects and advantages of this invention are as follows:

[0023] This invention incorporates a palm fruit bunch guiding mechanism and an insertion and cutting mechanism. The insertion and cutting mechanism first secures the palm fruit bunch by inserting a fixing rod into it. Then, a cutter cuts the base of the bunch. When the fixing rod is reset, the cut palm fruit bunch falls into the inlet ring frame of the guiding mechanism and is directly transported to the truck bed by a rubber corrugated pipe. This method of first inserting and fixing, then cutting, and finally resetting ensures that the palm fruit bunch falls into the inlet ring frame even with a slight tilt in the guiding mechanism, reducing the difficulty of transporting the bunch. Compared to existing technologies, this invention can directly transport the cut palm fruit bunch into the truck bed, eliminating the need for frequent manual loading and avoiding the loss of palm fruit due to it falling directly to the ground. This increases palm fruit yield, reduces harvesting costs, and improves loading efficiency.

[0024] This invention can remove palm leaves located below the palm fruit bunches, while preventing the fallen palm leaves from being transported into the transport vehicle's cargo bed. This ensures that the cut palm fruit bunches can fall and be transported normally while avoiding the transport of excess waste. Attached Figure Description

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1

[0033] This invention provides, for example Figure 1-Figure 5 The palm fruit harvester shown includes a telescopic lifting arm 1. An adjustment component 2 is fixedly connected to the top of the telescopic lifting arm 1. A palm fruit bunch guiding mechanism 3 is fixedly arranged on the right side of the adjustment component 2. An insertion cutting mechanism 4 and a plurality of evenly distributed blade blocking mechanisms 5 are arranged inside the top opening of the palm fruit bunch guiding mechanism 3. A fixing component 6 is arranged at the bottom right side of the palm fruit bunch guiding mechanism 3.

[0034] like Figure 2 As shown, the adjustment assembly 2 includes a back plate 21, a fixed plate 22, a fixed block 23, a fixed pin 24, a movable plate 25, and a first adjusting hydraulic cylinder 26. Two fixed plates 22 are provided, both fixedly mounted on the left side of the back plate 21. The fixed block 23 is slidably inserted between the two fixed plates 22 and fixedly mounted at the end of the telescopic lifting arm 1. Both the fixed plate 22 and the fixed block 23 have through-holes. The fixed pin 24 is inserted into the inner side of the through-hole. The movable plate 25 is movably connected to the right side of the back plate 21 via a pin. One end of the first adjusting hydraulic cylinder 26 is movably connected to the back plate 21 via a pin, and the other end is movably connected to the movable plate 25 via a pin.

[0035] By setting up the above structure, when the first adjusting hydraulic cylinder 26 extends or retracts, the movable plate 25 drives the palm fruit bunch guiding mechanism 3 to rotate around the pin shaft, thereby adjusting the tilt angle of the palm fruit bunch guiding mechanism 3 so that the palm fruit bunch guiding mechanism 3 can be located directly below the palm fruit bunch.

[0036] like Figure 3 As shown, the inlet ring frame 31 of the palm fruit bunch guiding mechanism 3 is fixedly installed on the right side of the movable plate 25. A rubber corrugated pipe 32 is fixedly connected to the bottom of the inlet ring frame 31, and an outlet ring frame 33 is fixedly installed at the bottom of the rubber corrugated pipe 32.

[0037] By setting up the above structure, the palm fruit bunches are detached from the outside of the fixed insertion rod 48 and fall into the inside of the inlet ring frame 31 under the action of gravity. The rubber corrugated pipe 32 guides and transports the palm fruit bunches. Finally, the palm fruit bunches pass through the outlet ring frame 33 and fall into the inside of the transport vehicle. During this process, palm fruits that accidentally detach are also collected inside the transport vehicle by being transported by the rubber corrugated pipe 32.

[0038] like Figure 4 As shown, the C-shaped plate 41 in the insertion cutting mechanism 4 is fixedly installed inside the right side of the entrance ring frame 31. A screw 42 is rotatably nested inside the C-shaped plate 41 via a bearing. A motor 43, which is connected to the screw 42, is fixedly installed at the bottom of the C-shaped plate 41. A first lifting plate 44 is sleeved on the outside of the screw 42. The first lifting plate 44 slides against the inner wall of the C-shaped plate 41. A cutter 45 is fixedly installed on the top right side of the first lifting plate 44. A buffer spring 46 is fixedly connected to the top center of the first lifting plate 44. A second lifting plate 47 is fixedly installed at the top of the buffer spring 46. The second lifting plate 47 slides vertically against the outside of the cutter 45 and slides against the inner wall of the C-shaped plate 41. The second lifting plate 47 slides against the outside of the screw 42. A fixed insertion rod 48 is fixedly installed on the top left side of the second lifting plate 47. A filling block 49 is fixedly installed on the left side of the C-shaped plate 41.

[0039] By setting up the above structure, when the insertion and cutting mechanism 4 moves to below the palm fruit bunch, the motor 43 drives the screw 42 to rotate continuously. When the screw 42 rotates, it drives the first lifting plate 44, guided by the U-shaped plate 41, to move continuously upward. When the first lifting plate 44 moves upward, it drives the cutter 45 to move upward. At the same time, the buffer spring 46 drives the second lifting plate 47 to move upward. When the second lifting plate 47 moves upward, it drives the fixed insertion rod 48 to move upward synchronously. As the second lifting plate 47 moves upward continuously, the fixed insertion rod 48 is inserted into the palm fruit bunch above it. After the top of the lifting plate 47 is attached to the inner wall of the U-shaped plate 41, the second lifting plate 47 cannot continue to move upward. During the subsequent upward movement of the first lifting plate 44, the first lifting plate 44 compresses the buffer spring 46 and drives the cutter 45 to cut the root of the palm fruit bunch. Then the motor 43 drives the screw 42 to rotate in the opposite direction, and the first lifting plate 44 moves down to reset. When the fixed insertion rod 48 moves down to reset, under the push of the U-shaped plate 41, the palm fruit bunch is separated from the outside of the fixed insertion rod 48 and falls into the inside of the entrance ring frame 31 under the action of gravity.

[0040] like Figure 3As shown, the fixing component 6 includes an L-shaped plate 61, a clamping plate 62, and a locking bolt 63. The L-shaped plate 61 is fixedly disposed on the bottom right side of the outlet ring frame 33, the clamping plate 62 is fixedly disposed on the bottom of the L-shaped plate 61, and the locking bolt 63 passes through the right side of the L-shaped plate 61 and is threadedly connected to the L-shaped plate 61.

[0041] By setting up the above structure, the L-shaped plate 61 and the clamping plate 62 can be sleeved on the top outer side of the transport vehicle bed. Then, the two locking bolts 63 are rotated until the clamping plate 62 and the two locking bolts 63 clamp and fix the transport vehicle bed. At this time, the outlet ring frame 33 is located directly above the transport vehicle bed.

[0042] Example 2

[0043] This invention also discloses a palm fruit harvesting method using a palm fruit harvester with a telescopic lifting arm, specifically including the following steps:

[0044] S2. Sleeve the L-shaped plate 61 and the clamping plate 62 onto the outer top of the transport vehicle bed, and then rotate the two locking bolts 63 until the clamping plate 62 and the two locking bolts 63 clamp and fix the transport vehicle bed. At this time, the outlet ring frame 33 is located directly above the transport vehicle bed.

[0045] S3. The first adjusting hydraulic cylinder 26 extends or retracts, causing the movable plate 25 to rotate around the pin shaft to drive the palm fruit bunch guiding mechanism 3 to rotate, thereby adjusting the tilt angle of the palm fruit bunch guiding mechanism 3 so that the palm fruit bunch guiding mechanism 3 can be located directly below the palm fruit bunch.

[0046] S4. The motor 43 drives the screw 42 to rotate continuously. When the screw 42 rotates, it drives the first lifting plate 44, which is guided by the C-shaped plate 41, to move upward continuously. When the first lifting plate 44 moves upward, it drives the cutter 45 to move upward. At the same time, the second lifting plate 47 moves upward through the buffer spring 46. When the second lifting plate 47 moves upward, it drives the fixed insertion rod 48 to move upward synchronously. As the second lifting plate 47 moves upward continuously, the fixed insertion rod 48 is inserted into the palm fruit bunch above it.

[0047] S5. After the top of the second lifting plate 47 is in contact with the inner wall of the C-shaped plate 41, the second lifting plate 47 can no longer move upward. During the subsequent upward movement of the first lifting plate 44, the first lifting plate 44 compresses the buffer spring 46 and simultaneously drives the cutter 45 to cut the root of the palm fruit bunch.

[0048] S6. The motor 43 drives the screw 42 to rotate in the opposite direction, and the first lifting plate 44 moves down to reset. When the subsequent fixed rod 48 moves down to reset, under the push of the shaped plate 41, the palm fruit bunches are separated from the outside of the fixed rod 48 and fall into the inside of the entrance ring frame 31 under the action of gravity.

[0049] S7. After the palm fruit bunch detaches from the outside of the fixed rod 48 and falls into the inside of the inlet ring frame 31 under the action of gravity, the rubber corrugated pipe 32 guides and transports the palm fruit bunch. Finally, the palm fruit bunch passes through the outlet ring frame 33 and falls into the inside of the transport vehicle. During this process, palm fruits that accidentally detach also fall into the inside of the transport vehicle and are collected under the transmission of the rubber corrugated pipe 32.

[0050] Example 3

[0051] Unlike the above embodiments, the palm fruit bunch guiding mechanism 3 has multiple evenly distributed blade blocking mechanisms 5 on the inner side of the top opening.

[0052] like Figure 5 As shown, the blade blocking mechanism 5 includes a fixed frame 51, a rotating shaft 52, a blocking plate 53, and a return torsion spring 54. The fixed frame 51 is fixedly installed inside the inlet annular frame 31. The rotating shaft 52 is rotatably nested inside the fixed frame 51 via a bearing. The blocking plate 53 is fixedly sleeved on the middle of the outer side of the rotating shaft 52. Two return torsion springs 54 are provided, and the two return torsion springs 54 are respectively sleeved on both ends of the outer side of the rotating shaft 52. Each return torsion spring 54 is fixedly connected between the inner wall of the fixed frame 51 and the blocking plate 53.

[0053] By setting up the above structure, due to the growth characteristics of palm leaves, some palm leaves will be located below the palm fruit bunch. If the root of the palm fruit bunch is cut directly, the two adjacent palm leaves will often block the palm fruit bunch and prevent it from falling. Therefore, if the above situation occurs, the palm leaves can be cut with the cutter 45. The cut palm leaves will first fall on the top of multiple blocking plates 53 under the action of gravity. However, they are light and cannot drive the blocking plates 53 to rotate. Only the roots fall on the top of multiple blocking plates 53. Then, under the action of gravity, they will naturally tilt to one side until they fall from the top of multiple blocking plates 53.

[0054] When the palm fruit bunch is pressed on top of multiple baffles 53, the heavier palm fruit bunch causes the multiple baffles 53 to rotate around the rotating shaft 52 to avoid it, until the palm fruit bunch falls into the rubber bellows 32 and is transmitted by the rubber bellows 32. Then the reset torsion spring 54 drives the baffles 53 to rotate and reset.

[0055] Example 4

[0056] Unlike the above embodiments, a palm fruit harvester with a telescopic lifting arm also includes a walking device. The top of the walking device is provided with a steering device for turning the telescopic lifting arm 1. The telescopic lifting arm 1 is movably connected to the top of the steering device via a pin. A second adjusting hydraulic cylinder for adjusting the tilt of the telescopic lifting arm 1 is also movably connected between the telescopic lifting arm 1 and the steering device.

[0057] By setting up the above structure, the invention can be moved to a position that is convenient for picking palm fruit bunches by using the walking device. Then, the telescopic lifting arm 1 is rotated by the steering device, so that the telescopic lifting arm 1 moves the palm fruit bunch guiding mechanism 3 closer to the palm tree. During this process, the telescopic lifting arm 1 continues to extend until the palm fruit bunch guiding mechanism 3 moves directly under the palm fruit bunch.

[0058] It should also be noted that the telescopic lifting arm 1, the walking device and the steering device are all solutions that have been disclosed in the prior art and are not essential technical features of this application. Therefore, this application will not elaborate on their specific structures here.

[0059] Finally, it should be noted that the above description 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 foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
