Description

Technical Field

[0001] This application relates to the field of plant topping technology, and more particularly to an electric plant topping machine. Background Technology

[0002] Plant pruning is a method used to control plant height, prevent the top of the main branch from growing too tall and affecting the growth of lateral buds, or increase plant yield. Specifically, it refers to pinching off the top leaves and buds of the main branch or excessively tall lateral branches after the plant has grown to a certain height. This encourages the plant to branch more, thicken, and become fuller, increasing yield and ornamental value. It also removes apical dominance, inhibits vegetative growth, promotes reproductive growth, and encourages the plant to flower and bear more fruit.

[0003] Currently, there are some topping machines on the market that can topping plants. Topping machines are generally long and thin rod-shaped structures, including a machine head, a rod body, and a power supply unit. The machine head is installed at the top of the rod body and includes a motor and blades. The motor drives the blades to rotate, thus topping the plant. The power supply unit is connected to the bottom of the rod body to supply power to the motor.

[0004] When topping different plants, the blades need to cut at different angles to achieve the desired effect. However, most topping machines have their heads fixed directly to the shaft, making angle adjustment impossible. The angle can only be adjusted to a certain extent by the operator's arm, which is inconvenient and can easily lead to operator fatigue. Therefore, this application proposes an electric topping machine for plants. Utility Model Content

[0005] This application provides an electric plant topping machine. By adjusting the button, the motor base can be locked and released, allowing the motor base to rotate and adjust the angle of the blades. This eliminates the need for manual adjustment by the topping operator, reducing workload.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0007] An electric plant topping machine includes a pole, a power supply, and a head assembly. The power supply is located at the bottom of the pole. The head assembly includes a fixing tube, a motor base, a motor, an adjustment button, and a blade. The fixing tube is mounted on the pole, and its top end forms a horizontal tube. The motor base is rotatably connected to the horizontal tube, and the motor is mounted on the motor base. The blade is connected to the output shaft of the motor, and the motor is electrically connected to the power supply. The first end of the horizontal tube has multiple first slots evenly distributed along the circumference of the horizontal tube. The second end of the horizontal tube has a support plate. One end of the motor base has a mounting hole. The mounting hole is coaxial with the transverse tube. The inner wall of the mounting hole is provided with multiple second slots, the number of which is equal to the number of first slots. The adjustment button is slidably connected in the mounting hole. The adjustment button is provided with multiple ribs, the number of which is equal to the number of second slots. The ribs are engaged in the first and second slots. A spring is provided between the adjustment button and the support plate. When an external force is applied to bring the adjustment button closer to the support plate, the ribs separate from the second slots. When the external force is removed, the adjustment button moves away from the support plate under the action of the spring, and the ribs engage with the second slots.

[0008] During use, the power supply powers the motor, which drives the blade to rotate, achieving the tipping effect. When the blade angle needs adjustment, press the adjustment button. The button moves closer to the support plate and compresses the spring, causing the rib to separate from the second locking slot. The second locking slot is no longer restricted, allowing the motor mount to rotate relative to the transverse tube, thus changing the angle between the motor and the blade. After adjustment, stop pressing the adjustment button. The button, under the spring's return force, moves away from the support plate, causing the rib to re-engage with the second locking slot, thus limiting the second locking slot and the motor mount. The angle adjustment is now complete.

[0009] Compared to existing technologies, this electric plant topping machine allows for the locking and unlocking of the motor base via an adjustment button, enabling the motor base to rotate and adjust the blade angle. This eliminates the need for manual adjustment by the topping operator, reducing workload.

[0038] Embodiments of this application provide a plant electric topping machine, such as... Figure 1 As shown, it includes a pole 100, a power supply 200, and a head assembly 300. The pole 100 is a structure that supports and mounts other components, the power supply 200 can provide electrical energy, and the head assembly 300 is a component that realizes the topping of plants.

[0039] like Figure 1 As shown, the pole 100 is a slender rod-shaped object. A person holding the pole 100 can reach a certain height. A power supply 200 is located at the bottom of the pole 100 and can provide electrical energy to power other components.

[0040] like Figure 2 As shown, the head assembly 300 includes a fixing tube 400, a motor base 500, a motor 600, an adjustment button 700, and a blade 800. The fixing tube 400 is mounted on the rod 100 to fix the entire head assembly 300.

[0041] like Figure 2 and Figure 3As shown, the top end of the fixed tube 400 forms a horizontal tube 410, the motor base 500 is rotatably connected to the horizontal tube 410, the motor 600 is set on the motor base 500, the blade 800 is connected to the output shaft of the motor 600, the motor 600 is electrically connected to the power supply 200, and when the power supply 200 is turned on, the motor 600 can drive the blade 800 to rotate, thereby achieving tipping.

[0042] like Figure 3 and Figure 4 As shown, the first end of the transverse tube 410 is provided with a plurality of first slots 421, which are evenly distributed along the circumference of the transverse tube 410. The second end of the transverse tube 410 is provided with a support plate 431. One end of the motor base 500 is provided with a mounting hole 530, which is coaxial with the transverse tube 410. The inner wall of the mounting hole 530 is provided with a plurality of second slots 540, the number of which is equal to the number of first slots 421.

[0043] like Figure 2 and Figure 5 As shown, the adjustment button 700 is slidably connected within the mounting hole 530. The adjustment button 700 has multiple protruding ribs 710, the number of which is equal to the number of multiple second slots 540. The protruding ribs 710 are engaged within the first slot 421 and the second slot 540, at which point the motor base 500 and the transverse tube 410 remain fixed. A spring is provided between the adjustment button 700 and the support plate 431.

[0044] When an external force is applied to bring the adjustment button 700 close to the support plate 431, the adjustment button 700 compresses the spring, the protruding rib 710 separates from the second slot 540, and the motor base 500 can rotate around the transverse tube 410 to achieve angle adjustment. When the external force is removed, the adjustment button 700 moves away from the support plate 431 under the action of the spring, the protruding rib 710 engages with the second slot 540, the motor base 500 is limited and no longer rotates, and can be sharpened.

[0045] During use, power supply 200 supplies power to motor 600, enabling motor 600 to drive blade 800 to rotate, achieving tipping. When it is necessary to adjust the angle of blade 800, press adjustment button 700. Adjustment button 700 moves closer to support plate 431 and compresses spring, causing rib 710 to separate from second slot 540. Second slot 540 is no longer restricted, allowing motor base 500 to rotate relative to transverse tube 410, thereby changing the angle between motor 600 and blade 800. After adjustment, stop pressing adjustment button 700. Adjustment button 700 moves away from support plate 431 under the spring's rebound, causing rib 710 to re-engage with second slot 540, achieving the limit of second slot 540 and motor base 500, thus ending the angle adjustment.

[0046] Compared to existing technologies, this electric plant topping machine allows the motor base 500 to be engaged and disengaged via adjustment button 700, enabling the motor base 500 to rotate and adjust the angle of the blade 800. This eliminates the need for manual adjustment by the topping operator, reducing workload.

[0047] In some embodiments, such as Figure 3 As shown, the fixed tube 400 includes a left half tube 440 and a right half tube 450, which are interlocked and fixedly connected by bolts for easy installation and connection with the rod body 100. The upper end of the left half tube 440 forms a left transverse half tube 420, and the upper end of the right half tube 450 forms a right transverse half tube 430. The left transverse half tube 420 and the right transverse half tube 430 are coaxial. A first slot 421 is provided in the left transverse half tube 420, and a support plate 431 is provided in the right transverse half tube 430. A spring can pass through the left transverse half tube 420 and be installed on the support plate 431.

[0048] In some embodiments, such as Figure 4 As shown, the motor mount 500 includes a left half-mount 510 and a right half-mount 520, which are interlocked and fixedly connected by bolts. The upper parts of the left half-mount 510 and the upper parts of the right half-mount 520 form a receiving cavity for accommodating the motor 600. Both the left half-mount 510 and the right half-mount 520 are provided with clamping plates 550 for holding the motor 600, which facilitates the installation of the motor 600. A mounting hole 530 is provided on the lower part of the left half-mount 510, and the mounting hole 530 is coaxial with the left transverse half-tube 420. The adjustment button 700 is slidably connected to the mounting hole 530 to realize the installation of the left half-mount 510 and the left transverse half-tube 420.

[0049] In some embodiments, such as Figure 2 As shown, the front end of the motor base 500 is provided with a guard plate 900. The guard plate 900 is located between the motor base 500 and the blade 800. It can protect the blade 800, prevent the tipping personnel from accidentally touching the blade 800, and also reduce the splashing of broken leaves and other debris during the tipping process.

[0050] In some embodiments, such as Figure 6 As shown, the rod body 100 includes an upper tube 110, a lower tube 120, and a handle housing 130. The upper tube 110 is slidably connected inside the lower tube 120, and the upper end of the upper tube 110 is connected to the fixed tube 400, thus connecting the rod body 100 to the fixed tube 400. The handle housing 130 is connected to the lower end of the lower tube 120, and the power supply 200 is disposed inside the handle housing 130.

[0051] like Figure 6As shown, a locking sleeve 140 is provided at the connection between the upper tube 110 and the lower tube 120. A locking wrench 150 is provided on the locking sleeve 140. When the locking wrench 150 is tightened, the upper tube 110 and the lower tube 120 remain fixed. When the locking wrench 150 is loosened, the upper tube 110 can slide relative to the lower tube 120. In this way, by adjusting the locking wrench 150, the sliding and locking of the upper tube 110 and the lower tube 120 can be realized, thereby achieving the telescopic control of the entire rod 100.

[0052] like Figure 6 As shown, the upper tube 110 and the lower tube 120 are equipped with a cable 160, which is formed into a spiral spring shape, allowing the cable 160 to extend and shorten. The cable 160 is used to connect the motor 600 and the power supply 200. When the upper tube 110 moves away from the lower tube 120, the length of the entire rod 100 increases, and the cable 160 is also stretched, allowing for tipping at a higher position.

[0053] In some embodiments, such as Figure 6 and Figure 7 As shown, the upper tube 110 is provided with an upper positioning hole 111, the left half tube 440 is provided with a first positioning tube 441, the first positioning tube 441 is provided with a first baffle 442, the first baffle 442 is provided with a first through hole, and the right half tube 450 is provided with a second positioning tube 451, the second positioning tube 451 is provided with a first internal thread. Both the first positioning tube 441 and the second positioning tube 451 pass through the upper positioning hole 111, and the bolt passes through the first through hole and engages with the first internal thread. When the left half tube 440 and the right half tube 450 are engaged, the first positioning tube 441 and the second positioning tube 451 both pass through the upper positioning hole 111 of the upper tube 110, and then the first positioning tube 441 and the second positioning tube 451 are fixedly connected by bolts. In this way, the upper tube 110 is installed into the left half tube 440 and the right half tube 450, that is, the fixed tube 400 is installed onto the rod body 100.

[0054] Similarly, such as Figure 6 and Figure 8 As shown, the lower tube 120 is provided with a lower positioning hole 121, and the handle housing 130 includes a left half housing 131 and a right half housing 132. The left half housing 131 and the right half housing 132 are interlocked and fixedly connected by bolts. The left half housing 131 is provided with a third positioning tube 133, and a second baffle 134 is provided inside the third positioning tube 133. The second baffle 134 is provided with a second through hole. The right half housing 132 is provided with a fourth positioning tube 135, and a second internal thread is provided inside the fourth positioning tube 135. Both the third positioning tube 133 and the fourth positioning tube 135 pass through the lower positioning hole 121. The bolt passes through the second through hole and engages with the second internal thread, so that the handle housing 130 can be installed on the lower tube 120.

[0055] In some embodiments, such as Figure 6As shown, the upper tube 110 has an upper plug 112 at its upper end, with an upper through hole. The lower tube 120 has a lower plug 122 at its lower end, with a lower through hole. The upper end of the cable 160 passes through the upper through hole, and the lower end of the cable 160 passes through the lower through hole. Both the upper plug 112 and the lower plug 122 are made of rubber. The cable 160 contacts the upper plug 112 and the lower plug 122, reducing the possibility of the cable 160 being cut. The lower tube 120 has a sponge sleeve 123 for easy handling by personnel.

[0056] In some embodiments, such as Figure 9 As shown, the lower ends of both the left half-shell 131 and the right half-shell 132 are open. The lower end of the power supply 200 has a rear shell 210. The power supply 200 passes through the openings and is installed inside the left half-shell 131 and the right half-shell 132. The rear shell 210 closes the openings. The power supply 200 can be a battery pack, which is inserted into the left half-shell 131 and the right half-shell 132 through the openings. At the same time, the rear shell 210 is snapped into and fixed to the left half-shell 131 and the right half-shell 132, thus realizing the installation of the power supply 200.

[0057] In some embodiments, such as Figure 9 As shown, a control board 136 is located inside the handle housing 130. The control board 136 is electrically connected to the power supply 200 and the cable 160. The control board 136 has a switch, which protrudes from the handle housing 130. The operator can operate the switch from the handle housing 130, making it convenient to control the entire device.
