Description
Technical Field
[0001] The utility model relates to the technical field of mowing agricultural machinery, in particular to an angle-adjustable shock-absorbing mowing device. Background Art
[0002] Mowing equipment refers to equipment used to cut weeds. Currently, there are many types of mowing equipment, mainly backpack mowers and hand-push mowers. Hand-push mowers are mainly used for trimming large areas of flat grass, suitable for scenes such as golf courses. Backpack mowers are mainly used in farmland or mountainous areas with more complicated conditions. Backpack mowers mainly include a fuel engine carried on the back, a handheld long pole, and a mowing head installed at the end of the long pole. Although backpack mowers can be used in more complex scenes, due to their own weight, long-term use is more tiring, especially in farmland such as terraces and mountains. When it is necessary to remove weeds on inclined or straight walls, it is difficult for the operator to hold the handheld long pole high for a long time and move it back and forth to mow the grass, which not only leads to slow mowing operations and low efficiency, but also greatly increases the labor burden of the operator.
[0003] In view of this, an angle-adjustable shock-absorbing mowing equipment is designed so that it can facilitate operators to easily cut weeds on inclined walls or straight walls, while also improving the operator's operating comfort and reducing labor burden. Utility Model Content
[0004] The utility model aims to provide an angle-adjustable shock-absorbing grass cutting device to solve the problems described in the background technology.
[0005] The technical solution of the utility model is achieved in this way:
[0006] The mowing device according to claim 1, wherein the mowing device comprises a back-mounted mower and a chassis, wherein the back-mounted mower comprises a power machine, a flexible shaft, a hand-held long pole with a power transmission function and a mowing head, wherein one end of the hand-held long pole is connected to the mowing head, and the other end is connected to the power machine through the flexible shaft. The bottom of the chassis is fixedly provided with three oblique rods, one oblique rod is arranged at the front end of the chassis and extends forward and downward, and two oblique rods are arranged at the rear end of the chassis and extend outward and backward and downward. Wheels are installed at the bottom of the oblique rods, and a vertical push rod is fixedly provided at the rear of the upper end of the chassis, a sliding sleeve that can be fixed on the push rod is provided with a sliding cylinder, and a shock-absorbing waist pushing mechanism facing the rear of the bottom plate is fixedly provided on the sliding cylinder, and a push handle is also provided on the top of the push rod, and a telescopic rod with a fixed telescopic length is also fixedly provided at the front of the upper end of the chassis, a rolling ball is universally rotatably installed on the top of the telescopic rod, a through hole is opened at the center line of the rolling ball, the hand-held long pole is slidably and rotatably penetrated in the through hole, and the power machine is arranged on the chassis.
[0007] When using the above solution, the operator can push the handle to move the entire device, and the oblique rods extend forward and rearward respectively to increase the ground contact area of the entire device, which not only increases stability during movement, but also reduces the area of the chassis and reduces the weight of the entire device.
[0008] The slide can be adjusted in height so that the damping waist push mechanism on the slide can be aligned with the waist and hips of the operator. The use of the waist and hips and the push of the hands can increase the stability of the equipment when moving, making it easier to push. At the same time, the damping waist push mechanism can reduce the impact of the equipment on the waist and hips, improving comfort. During the operation, when the operator wants to move a short distance at the same time while operating the handheld long pole with both hands, the damping waist push mechanism can be used to achieve this.
[0009] When the operator uses the hand-held pole to mow the grass, the hand-held pole uses the rolling ball as the fulcrum, and uses the lever principle to make the hand-held pole behind the rolling ball longer than the hand-held pole in front of the rolling ball, so that it will be easier and more labor-saving to pry and raise the mowing head. At the same time, the rolling ball can be universally rotated, and the hand-held pole can also rotate in the rolling ball, so the operator can easily adjust the mowing head to any angle to cut weeds on inclined or straight walls. In addition, the height of the rolling ball can be adjusted by adjusting the extension of the telescopic rod to achieve the most comfortable fulcrum height for different operators.
[0010] After the power machine is loaded onto the chassis, the operator no longer needs to carry the power machine for mobile operations, and the labor burden is relatively reduced.
[0011] A further technical solution is that the shock-absorbing lumbar push mechanism includes a spring shock-absorbing rod arranged behind the slide cylinder, the front end of the spring shock-absorbing rod is fixedly connected to the rear of the slide cylinder, the rear end of the spring shock-absorbing rod is fixedly connected to a mounting plate, the rear end surface of the mounting plate is provided with a soft pad, and the left and right sides of the mounting plate are also provided with restraint belts.
[0012] When using the above solution, the operator wraps the restraint belt around the waist and hips, so that the operator can turn around in the restraint belt without being too loose. When mowing, the operator is generally in an incomplete sideways state. When the equipment needs to be pushed a short distance, the operator uses the side of the waist and hips to push the soft pad to move the equipment forward, or pulls the restraint belt to move the equipment backward. The combination of the spring shock absorber rod and the soft pad can effectively absorb the impact of bumps or setbacks on the waist and hips during the forward movement of the equipment, thereby improving the operator's comfort.
[0013] A further technical solution is that the telescopic rod includes a vertical sleeve fixed to the upper end of the base frame, a sliding rod is slidably inserted in the sleeve, a side wall of the sleeve is provided with a plurality of second through holes passing through the center line of the sleeve from top to bottom, a third through hole passing through the center line of the sliding rod is provided on the side wall of the sliding rod, and after the second through hole and the third through hole are aligned, a latch member is passed through them at the same time to fix them.
[0014] When using the above solution, the slide bar can be slid up and down in the sleeve by pulling out the latch piece. After adjusting to a suitable position, the third through hole of the slide bar is aligned with the second through hole of the sleeve. The slide bar can be fixed in the sleeve by passing the latch piece through the aligned second through hole and the third through hole at the same time, thereby fixing the height of the top of the slide bar.
[0015] A further technical solution is that a lower mounting rod is fixedly provided on the top of the left and right side walls of the slide bar, the top of the lower mounting rod extends upward and protrudes in the direction away from the center line of the slide bar to form a lower pressure block, the top of the slide bar is also provided with a lower ball groove downwardly, a clamping block is also provided just above the slide bar, and an upper ball groove is upwardly provided at the bottom of the clamping block, and an upper mounting rod is fixedly provided on the left and right side walls of the clamping block, the bottom of the upper mounting rod extends downward and protrudes in the direction away from the center line of the slide bar to form an upper pressure block, the upper and lower pressure blocks on the same side abut against each other and are also fixed by a locking piece, so that the two upper mounting rods and the two lower mounting rods together form an annular frame for accommodating a rolling ball, the bottom of the rolling ball is slidably embedded in the lower ball groove, and the top of the rolling ball is slidably embedded in the upper ball groove.
[0016] When the above solution is used, when the rolling ball needs to be installed, first place the rolling ball in the lower ball groove at the top of the slide bar, then place the clamp block, and cover the upper ball groove on the top of the rolling ball, so that the upper pressing block on the same side is aligned with the lower pressing block, and the upper pressing block and the lower pressing block are locked with a locking piece, so that the rolling ball can be restricted between the clamp block and the slide bar, and the function of universal rotation of the rolling ball between the clamp block and the slide bar can be realized by applying lubricating oil or grease in the upper ball groove and the lower ball groove. When the rolling ball needs to be removed, loosen the locking piece to make the clamp block detach from the slide bar, and the rolling ball can be taken out.
[0017] A further technical solution is that the side wall of the push rod is provided with a plurality of first through holes passing through the center line of the push rod from top to bottom, and the side wall of the slide cylinder is provided with a fourth through hole passing through the center line of the slide cylinder. After the first through hole and the fourth through hole are aligned, a latch is passed through them at the same time to fix them.
[0018] When using the above solution, first take out the latch member, adjust the height of the slide to a suitable height for the operator, align the fourth through hole with the corresponding first through hole, insert the latch member, and the height of the slide can be fixed.
[0019] A further technical solution is that the push rod is a rectangular rod, the inner wall cross section of the slide cylinder is rectangular, and the four inner walls of the slide cylinder and the four outer walls of the push rod correspond to each other and fit each other.
[0020] By setting the push rod as a rectangular rod and cooperating with the inner wall of the sliding cylinder, the sliding cylinder can only slide on the push rod but cannot rotate.
[0021] The beneficial effects of the utility model are:
[0022] 1. By setting up the chassis and wheels, the backpack mower is dispersed on the chassis. The operator pushes the handle to move the entire device, reducing fatigue. The inclined rods extend forward and backward respectively, which can increase the ground contact area of the entire device, not only increasing the stability during movement, but also reducing the area of the chassis and reducing the weight of the entire device.
[0023] 2. By adjusting the height of the slide, the damping waist push mechanism on the slide can be aligned with the waist and hips of the operator. By using the push at the waist and hips and the push of the hands, the stability of the equipment during movement can be increased, making the push easier. At the same time, the damping waist push mechanism can reduce the impact of the equipment on the waist and hips, and improve comfort. During the operation, when the operator wants to move a short distance at the same time while operating the handheld long pole with both hands, the damping waist push mechanism can be used to achieve this, which improves the convenience of operation.
[0024] 3. By setting the universal rotating ball as the fulcrum and using the lever principle, the hand-held long pole behind the ball is longer than the hand-held long pole in front of the ball, which makes it easier and more labor-saving to pry and raise the mowing head. At the same time, the operator can easily adjust the mowing head to any angle to cut weeds on inclined or straight walls. And the height of the ball can also be adjusted by adjusting the extension of the telescopic rod to achieve the most comfortable fulcrum height for different operators.
