Description

Technical Field

[0001] The present application relates to the technical field of oil palm harvesting, and in particular to a pair of oil palm harvesting scissors. Background Art

[0002] Oil palm (Elaeis guineensis Jacq) is a tree of the genus Elaeis in the family Arecaceae. It has a tall stem and pinnately lobed leaves, which are clustered at the top of the stem. The pinnae are folded outwards, linear-lanceolate, and needle-like at the bottom, with wide petioles. Oil palm is suitable for a growing environment with high temperatures, abundant rainfall, and sufficient sunlight. It is afraid of wind, drought, and cold, and prefers a thick soil layer, loose topsoil, lightly sticky subsoil, and well-drained acidic sandy soil. The palm oil and palm kernel oil extracted from the oil palm fruit are highly nutritious edible oils and fats after refining. They can be used to make margarine, soap, lubricating oil, and cosmetics. Palm kernel oil is delicious. In addition to being eaten directly and used to make margarine, it is also used to make high-grade soaps, perfumed soaps, and various cosmetics. It has higher nutritional and economic value than palm oil.

[0003] In some related technologies, during the cultivation of oil palm, it is necessary to prune the petioles of the oil palm. Generally, manual scissors similar to those used for pruning fruit trees are used for pruning. For example, Chinese patent CN206294577U discloses a fruit tree pruning knife for pruning thicker fruit trees, comprising a pruning knife body, an upper handle being installed on the pruning knife body, a lower handle being installed below the upper handle, a cutting knife handle being fixedly installed on the front panel of the upper handle, and the lower part of the cutting knife handle being connected to a telescopic rope fixing seat on the lower handle through a telescopic rope. The utility model discloses a fruit tree pruning knife, firstly, a cutting knife is arranged on the fruit tree pruning knife. When pruning thicker fruit trees, the support rod on the lower handle supports the handle of the cutting knife, so that the cutting knife performs secondary squeezing on the fruit tree, making the pruning of the thicker fruit tree more convenient. Secondly, the support rod on the fruit tree pruning knife can be rotated. When facing small branches, the support rod can be rotated to a horizontal position, and the pruning can be completed without using the cutting knife. However, since the petiole of the oil palm leaf is hard and tough, it is not easy to cut it, so the planting personnel need to consume a lot of energy, and the working efficiency is also relatively low.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0041] Chinese patent CN206294577U discloses a fruit tree pruning knife for pruning thicker fruit trees. When in use, the petiole of the oil palm leaf is hard and tough, so it is not easy to cut it. This requires the planters to consume a lot of energy and the operation efficiency is relatively low.

[0042] In addition, the two cutting parts of the scissors of this structure are rotated at a hinge point, and the range of pruning is limited, especially for the relatively wide and flat petioles of oil palm.

[0043] The embodiment of the present application provides a pair of oil palm harvesting scissors to solve the problem in the related art that the petiole of oil palm is hard and tough, and it is difficult to cut it by manual pruning using traditional scissors.

[0044] See also Figure 1-Figure 6 , a pair of oil palm harvesting scissors, comprising:

[0045] A grip rod 1 is provided with a mounting circular groove 2 on the end surface of one end thereof; a guide groove 3 connected to the mounting circular groove 2 is provided on the outer circumference of the grip rod 1, and in the length direction of the grip rod, the length of the guide groove 3 and the length of the mounting circular groove 2 are equal;

[0046] A first driving motor 4 is arranged in the mounting circular groove 2 and is drivingly connected to a screw rod 5 coaxial with the mounting circular groove 2. A moving block 6 is provided on the outer thread sleeve of the screw rod 5. The moving block 6 is provided with a movable knife 7 which is radially arranged along the mounting circular groove 2 and penetrates the mounting circular groove 2;

[0047] The end mounting seat 8 is mounted on one end of the grip rod 1 having the mounting circular groove 2, and is provided with a fixed knife 9; in the length direction of the grip rod, the fixed knife 9 and the movable knife 7 are located on the same straight line; the screw rod 5 is rotatably connected to the end mounting seat 8.

[0048] When in use, the first drive motor 4 controls the screw rod 5 to rotate forward, thereby driving the movable knife 7 on the movable block 6 to move toward the fixed knife 9 to trim the oil palm petiole located between the movable knife 7 and the fixed knife 9; after pruning, the first drive motor 4 is reversed to drive the movable knife 7 away from the fixed knife 9, so as to facilitate the next shearing, thereby realizing automatic shearing and accelerating the pruning efficiency; in addition, the movable knife 7 and the fixed knife 9 are arranged at intervals on a straight line, which can be applied to a wider range, and the blades of the movable knife 7 and the fixed knife 9 are in the opposite direction of the width of the oil palm petiole, and the shearing force is applied along the thickness direction of the oil palm petiole to avoid shearing along the width direction of the oil palm petiole, thereby reducing the required shearing force.

[0049] Shearing along the width direction of the oil palm petiole requires not only shearing force but also force to squeeze the oil palm petiole, because the area in contact with the fixed knife 9 is small at this time; applying shearing force along the thickness direction of the oil palm petiole makes the area in contact with the fixed knife 9 large, which is convenient for shearing or pruning.

[0050] In addition, due to the threaded connection between the screw rod 5 and the moving block 6, it has the advantage of self-locking, ensuring that the relative position between the movable knife 7 and the fixed knife 9 is stable and the control is more accurate, and there will be no relative shaking when the first drive motor 4 is not rotating.

[0051] In some preferred embodiments, in addition to ensuring that the relative distance between the movable knife 7 and the fixed knife 9 is accurately controlled, it is also necessary to ensure that the movable knife 7 does not shake left and right during movement, and does not shake left and right when subjected to shearing force, that is, the blades of the two do not move in the same plane. Because the effect we want to achieve is to shear on both sides of the petiole thickness direction at the same time to speed up the shearing speed, the following settings are made:

[0052] refer to Figure 3-Figure 5 ;

[0053] The guide groove 3 is a V-shaped guide groove;

[0054] The moving block 6 includes a cylindrical portion 600 and a guide stopper 601; a thread groove threadedly connected to the screw rod 5 is provided inside the cylindrical portion 600; the guide stopper 601 is fixedly connected to the outer side of the cylindrical portion 600, and a movable knife 7 is provided thereon;

[0055] The guide limit block 601 is also provided with inclined surfaces on both sides of the movable knife 7 in the thickness direction, and the inclined surfaces are used to contact with the two side walls of the V-shaped guide groove.

[0056] Through the above arrangement, during the movement of the movable knife 7 and the process of shearing the petiole, the two side walls of the V-shaped guide groove and the inclined surface of the movable knife 7 are in mutual contact, which ensures that the movable knife 7 will not swing left and right, thereby ensuring the shearing effect.

[0057] Furthermore, in order to ensure the smooth movement of the movable knife 7 and to facilitate the provision of electrical energy to the first drive motor 4, the following settings are provided:

[0058] The outer diameter of the cylindrical portion 600 is equal to the inner diameter of the mounting circular groove 2, and a lubricating oil is provided between the two;

[0059] A central through hole is provided at the center of the mounting circular groove 2, which is toward the end of the grip rod 1 away from the end mounting seat 8, and the central through hole is used for arranging a power line.

[0060] In some preferred embodiments, in order to fix the end of the screw rod 5 away from the first drive motor 4 and provide an installation position for the fixed knife 9, the following settings are provided:

[0061] refer to Figure 7-Figure 9 ;

[0062] The first type, the end mounting seat 8 includes a mounting cylinder, a partition is provided in the mounting cylinder, and the partition divides the space in the mounting cylinder into a first part and a second part; one end of the gripping rod 1 having a mounting circular groove 2 is inserted into the first part, and is connected to the mounting cylinder by a first connecting screw 15; a circular hole is provided on the partition, and the end of the screw rod 5 away from the first driving motor 4 is successively penetrated by the mounting circular groove 2, the first part, the circular hole and the second part; the mounting cylinder is fixedly connected to the fixing knife 9.

[0063] The second type, the end mounting seat 8 includes a mounting cylinder, a partition is provided in the mounting cylinder, and the partition divides the space in the mounting cylinder into a first part and a second part; one end of the grip rod 1 having a mounting circular groove 2 is inserted into the first part, and is connected to the mounting cylinder by a first connecting screw 15; a circular hole is provided on the partition, and the end of the screw rod 5 away from the first drive motor 4 is passed through the mounting circular groove 2, the first part, the circular hole and the second part in sequence; a connecting plug rod is provided in the second part, and the connecting plug rod is connected to the mounting cylinder by a second connecting screw; a fixing knife 9 is fixed on the connecting plug rod.

[0064] The third type is that the end mounting seat 8 includes a mounting cylinder, and a second drive motor 10 is arranged in the mounting cylinder. The second drive motor 10 is arranged opposite to the output shaft of the first drive motor 4, and has the same rotation direction and speed; the second drive motor 10 is connected to the end of the screw rod 5 away from the first drive motor 4;

[0065] The second driving motor 10 divides the space in the mounting cylinder into a first part and a second part; one end of the grip rod 1 having the mounting circular groove 2 is inserted into the first part; a connecting plug rod is provided in the second part, and the connecting plug rod is connected to the mounting cylinder through a second connecting screw; a fixing knife 9 is fixed on the connecting plug rod.

[0066] Among the above three structural forms, the best embodiment is the third one, because the addition of a second drive motor 10 can increase the driving force of the moving block 6 to drive the movable knife 7 to move, thereby increasing the shearing force to adapt to the scene where the oil palm petiole has high hardness and strong toughness, and speed up the shearing efficiency.

[0067] In some preferred embodiments, at least one of the fixed knife 9 and the movable knife 7 is provided with a hollow groove 11; the hollow groove 11 can reduce stress concentration and avoid breakage.

[0068] In some preferred embodiments, during the process of pruning the oil palm petiole, the inner oil palm petiole needs to be pruned, but the outer oil palm petiole will block it, so the handle 1 needs to be bent to a certain extent to facilitate pruning, so the following settings are provided:

[0069] The handle 1 comprises a first section and a second section, the second section is provided with a mounting circular groove 2, and an elastic member 12 is provided between the first section and the second section.

[0070] The diameters of the first section and the second section are equal; the diameter of the elastic member 12 is smaller than the diameter of the second section; the elastic member 12 comprises an elastic rod having a cavity; the cavity is filled with magnetic powder; two semicircular steel plates 13 are adsorbed on the outer side of the elastic rod.

[0071] Through the above arrangement, when the handle 1 does not need to be bent, the semicircular steel plate 13 can be adsorbed on the outside of the elastic rod through the magnetic powder filled in the cavity; when bending is required, the semicircular steel plate 13 can be removed to meet different usage requirements.

[0072] Furthermore, the first section is provided with an anti-slip sleeve 14 and a control switch connected to the first drive motor 4 ; the control switch is used to control the first drive motor 4 to rotate forward or reverse.

[0073] Beneficial effects of this application:

[0074] 1. When in use, the first drive motor 4 controls the screw rod 5 to rotate forward, thereby driving the movable knife 7 on the movable block 6 to move toward the fixed knife 9 to prune the oil palm petiole located between the movable knife 7 and the fixed knife 9; after pruning, the first drive motor 4 reverses to drive the movable knife 7 away from the fixed knife 9, so as to facilitate the next shearing, thereby realizing automatic shearing and accelerating the pruning efficiency; in addition, the movable knife 7 and the fixed knife 9 are arranged at intervals on a straight line, so that the applicable range is wider, and the blades of the movable knife 7 and the fixed knife 9 are in the opposite direction of the width of the oil palm petiole, and the shearing force is applied along the thickness direction of the oil palm petiole to avoid shearing along the width direction of the oil palm petiole, thereby reducing the required shearing force. Shearing along the width direction of the oil palm petiole requires not only shearing force, but also force to squeeze the oil palm petiole, because the area in contact with the fixed knife 9 is small at this time; applying shearing force along the thickness direction of the oil palm petiole makes the area in contact with the fixed knife 9 large, which is convenient for shearing or pruning.

[0075] Second, during the movement of the movable knife 7 and the process of shearing the petiole, the two side walls of the V-shaped guide groove and the inclined surface of the movable knife 7 are in contact with each other, so that the movable knife 7 will not shake left and right, thereby ensuring the shearing effect.

[0076] 3. The second driving motor 10 is added to increase the driving force of the moving block 6 to drive the movable knife 7 to move, thereby increasing the shearing force to adapt to the scene where the oil palm petiole has high hardness and strong toughness, and speed up the shearing efficiency.
