Description

Technical Field

[0001] This invention relates to the field of garden weeding technology, specifically to a smart agriculture garden weeding device. Background Technology

[0002] Weeding devices are one of the most commonly used tools in agricultural labor.

[0003] For example, Chinese patent publication number "CN213073614U" discloses "an agricultural and garden weeding device," whose main structure includes a base plate, a shell, and a motor. A support leg is fixedly installed on the lower end face of the base plate, and universal rollers are fixedly installed at the bottom of the support leg. The shell is installed on the upper end face of the base plate, and a longitudinally arranged partition is fixedly installed in the middle of the shell. A motor is fixedly installed inside the shell on the left side of the partition, and the output end of the motor extends through the lower end face of the base plate and is fixedly fitted with a weeding blade. A grass-crushing collection trough is opened on the right side of the shell on the partition, and a grass-crushing collection mechanism is provided in the trough. A top cover is fixedly installed on the top of the shell, and a pair of symmetrically arranged push rods are fixedly installed on the outer wall of the right side of the shell. This agricultural and garden weeding device uses a drive motor to rotate the weeding blade, thereby cutting and removing weeds from the ground.

[0004] However, the above-mentioned agricultural and garden weeding device has the following two defects: First, the fixed weeding blades may break due to collision with hard objects during actual weeding. Once the blades break, they need to be replaced, and the cost of using the blades is relatively high. Second, the connection between the weeding blades and the rotor of the drive motor is a fixed structure, which makes it impossible for the device to adjust the weeding depth according to actual needs.

Utilizing the cutting function of a high-speed rotating weeding rope, it can effectively remove weeds. Furthermore, the weeding rope is inexpensive to use. In addition, the weeding rope and the rotating disk are connected by a ball joint.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 and Figure 2 A smart agricultural garden weeding device includes a weeding cart 1 with rollers 2 mounted on its bottom, a push rod 3 for moving the weeding cart 1, a main component mounting port 4 located in the middle of the weeding cart 1, a drive motor 6 fixedly mounted on the upper surface of the weeding cart 1 via a motor fixing housing 5, a first pulley 7 fixedly mounted on the rotor end of the drive motor 6, and a belt 8 fitted inside the first pulley 7. The upper surface of the weeding cart 1 is equipped with a power storage module and a current controller. The current controller controls the magnitude and switching of the current input from the power storage module to the drive motor 6, turning on the drive motor 6 and controlling the rotor speed. At this time, the weeding rope 98 rotates at high speed, and the operator can manually push the weeding cart 1 to remove the weeds.

[0021] For centrifugal weed removal and easy replacement, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A combined weeding mechanism 9 is required, which includes an upper rotating disk 91 and a lower rotating disk 92 located directly below the main component mounting port 4 and capable of rotation; two symmetrical rotating spheres 96 positioned inside the upper and lower rotating disks 91 and 92 and capable of rotation; and a weeding rope 98 with one end embedded inside the rotating spheres 96, capable of rotating and clearing weeds during rotation. During operation, a power storage module and a current controller are installed on the upper surface of the weeding cart 1. The current controller controls the power storage module to supply power to the drive motor 6. The magnitude of the input current and the switch, when the upper rotating disk 91 rotates, will cooperate with the lower rotating disk 92, so that the rotating ball 96 drives the grass trimming rope 98 to rotate at high speed. During the rapid drive, due to the resistance of the grass trimming rope 98, the rotating ball 96 will undergo adaptive angle changes until the grass trimming rope 98 rotates at high speed in a taut state. When it is necessary to replace the grass trimming rope 98, remove the fixing bolt 93, and then install the new grass trimming rope 98 and the rotating ball 96 inside the corresponding hemispherical mounting groove 95, and then install the fixing bolt 93.

[0022] For details regarding the specific structure of the combined weeding mechanism 9, please refer to [link / reference]. Figure 3 , Figure 4 and Figure 5 It includes an upper rotating disk 91 and a lower rotating disk 92 that can be connected by a fixing bolt 93. The upper surface of the upper rotating disk 91 is provided with a concave rod mounting groove 94. The circumferential sides of the upper rotating disk 91 and the lower rotating disk 92 are respectively provided with an integral upper semi-cylindrical protrusion structure 99 and a lower semi-cylindrical protrusion structure 910 on symmetrical sides. The upper semi-cylindrical protrusion structure 99 and the lower semi-cylindrical protrusion structure 910 located on the same side are respectively provided with a hemispherical mounting groove 95 with one end open. Each of the hemispherical mounting grooves is provided with a hemispherical mounting groove 95. Inside each groove 95 is a freely rotating sphere 96. The interior of the rotating sphere 96 is provided with a concave rope embedding groove 97. A mowing rope 98 is embedded in the rotating sphere 96 within the rope embedding groove 97. The structural radius of the hemispherical mounting groove 95 matches the structural radius of the rotating sphere 96. The structural depth of the hemispherical mounting groove 95 is greater than the structural radius of the rotating sphere 96 but less than the structural diameter of the rotating sphere 96. The rotation radius of the mowing rope 98 is less than the width of the weeding cart 1.

[0023] To enable the adjustment of the cleaning depth, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 6 and Figure 7A weeding depth adjustment mechanism 10 needs to be installed. Internally, it includes a longitudinal hollow shell 101 mounted inside the main component mounting port 4 via bearings, a lower telescopic rod 106 that rotates with the longitudinal hollow shell 101 and drives the upper rotating disk 91 to rotate, an external threaded rod 108 that adjusts the height of the lower telescopic rod 106 during rotation, and an external threaded rod 108 installed inside the longitudinal hollow shell 101 that generates preload on the threaded structure. The belt 8 drives the second pulley 1010 to rotate, which in turn drives the longitudinal hollow shell 101 to rotate. Since the cross-sectional shape of the rod body through hole 103 is consistent with the cross-sectional shape of the lower telescopic rod 106, both being multi-faceted... The structure is polygonal, and the cross-sectional dimensions of the rod through hole 103 match the cross-sectional dimensions of the lower telescopic rod 106. The lower telescopic rod 106 will drive the upper rotating disk 91 to rotate, realizing the function of transmitting the rotation state. When it is necessary to adjust the cleaning depth, the rotating cap 109 is rotated in a directional manner. At this time, the external thread rod 108 will rotate accordingly. Due to the threaded connection, the external thread rod 108 will cause the lower telescopic rod 106 to move longitudinally, thereby adjusting the working height of the straw rope 98. During the operation, the elastic force of the helical spring 107 will be transmitted between the internal thread structure and the external thread structure, so that a preload is generated between the two, thereby ensuring the stability of the thread structure during operation.

[0024] For details regarding the specific structure of the weeding depth adjustment mechanism 10, please refer to [link / reference]. Figure 6 and Figure 7The system includes a longitudinal component movable cavity 102 disposed inside a longitudinal hollow outer shell 101. The bottom end of the longitudinal hollow outer shell 101 has a rod through-hole 103 connecting the space below it and the bottom end of the longitudinal component movable cavity 102. The top end of the longitudinal hollow outer shell 101 has an internal threaded hole 104 connecting the space above it and the top end of the rod through-hole 103. A second pulley 1010 is fixedly installed on the outer circumferential wall near the top end of the longitudinal hollow outer shell 101, and the second pulley 1010 is linked to a first pulley 7 via a belt 8. An internal movable plate 105 capable of moving axially along the longitudinal component movable cavity 102 is placed inside the longitudinal hollow outer shell 101 within the longitudinal component movable cavity 102. A lower telescopic rod 106 penetrating the rod through-hole 103 is fixedly installed at the bottom end of the internal movable plate 105. The bottom end of the lower telescopic rod 106 is fixedly installed... Inside the rod mounting groove 94, the top of the built-in movable plate 105 is mounted with a rotatable external thread rod 108 via a bearing. The rod body of the external thread rod 108 is installed inside the internal thread hole 104 via a threaded structure. A rotating cap 109 is provided at the top of the external thread rod 108. A helical spring 107 that generates downward elastic pressure on the built-in movable plate 105 is placed around the rod body located inside the longitudinal component movable cavity 102. The cross-sectional shape of the rod body through hole 103 is consistent with the cross-sectional shape of the lower telescopic rod 106, both being polygonal structures. The cross-sectional dimensions of the rod body through hole 103 match the cross-sectional dimensions of the lower telescopic rod 106. The threaded structure includes an internal thread structure provided in the internal thread hole 104 and an external thread structure provided on the rod body of the external thread rod 108, and the internal thread structure matches the external thread structure.

[0025] In use, the upper surface of the weeding cart 1 is equipped with a power storage module and a current controller. The current controller controls the amount and switching of the current input from the power storage module to the drive motor 6, turning on the drive motor 6 and controlling the rotor speed. At this time, the belt 8 drives the second pulley 1010 to rotate, which in turn drives the longitudinal hollow shell 101 to rotate. Since the cross-sectional shape of the rod through hole 103 is consistent with the cross-sectional shape of the lower telescopic rod 106, both being polygonal structures, and the cross-sectional dimensions of the rod through hole 103 are consistent with those of the lower telescopic rod 106, the overall structure is consistent with the cross-sectional shape of the lower telescopic rod 106. With the cross-sectional dimensions of the lower telescopic rod 106 matched, the lower telescopic rod 106 will drive the upper rotating disk 91 to rotate. When the upper rotating disk 91 rotates, it will cooperate with the lower rotating disk 92, thereby causing the rotating ball 96 to drive the weeding rope 98 to rotate at high speed. During the rapid driving process, due to the resistance of the weeding rope 98, the rotating ball 96 will undergo adaptive angle changes until the weeding rope 98 rotates at high speed in a taut state. With the weeding rope 98 rotating at high speed, the staff can manually push the weeding cart 1 to remove the weeds it comes into contact with.
