Description

Technical Field

[0001] The invention relates to the technical field of weeding devices, in particular to a device for cleaning sedge vines for landscaping in complex areas. Background Art

[0002] In the field of gardening and greening, as people's requirements for beautification and maintenance of the ecological environment continue to increase, the diversity and complexity of garden landscapes are also increasing. However, a creeping plant called chicken shit vine often brings many troubles to the management of gardens. Chicken shit vine has extremely strong vitality and reproductive ability. It can spread and grow rapidly in various complex terrain environments. During its growth, it will compete with various ornamental plants in the garden for important resources such as sunlight, water, and nutrients, resulting in the growth of these ornamental plants being hindered, affecting the overall beauty of the garden landscape and the health and stability of the plant community. In addition, the wanton spread of chicken shit vine may also cause entanglement and damage to some infrastructure in the garden, such as fences, trails, irrigation pipes, etc., increasing the cost and difficulty of garden maintenance. Therefore, in order to effectively solve this problem, a chicken shit vine cleaning device is needed;

[0003] However, the existing weeding devices for landscaping still have the following problems during use: the garden weeding device cleans the chicken shit vine by rotating and cutting with a blade parallel to the ground at the bottom. In complex areas, the slope and unevenness of the ground vary greatly. When passing through the corners of uneven roads, the device as a whole will tilt in the direction of travel, causing the blade at the bottom to tilt synchronously, and the distance between the blade and the ground is closer. After the tilt, the avoidance space between the end and the ground is small, and it is easy to cut into the ground and collide directly. This makes the blade prone to damage such as chipping, curling or breaking, which greatly reduces the service life of the blade, which is not conducive to the cleaning work. In addition, in actual cleaning work, it may be necessary to adjust the corresponding cleaning components according to the distribution density of the chicken shit vine to improve the flexibility of the device in different cleaning scenarios.

[0004] Therefore, we propose a device for cleaning the landscaping of complex areas with the use of the sedge dung vine to solve the problems raised above. Summary of the invention

[0005] The purpose of the present invention is to provide a device for cleaning the C. shiitake mushrooms for landscaping in complex areas, so as to solve the problem that the existing C. shiitake mushrooms for landscaping in complex areas on the market proposed in the above-mentioned background technology is that when passing through the corners of uneven roads, the distance between the blade and the ground is closer, and the avoidance space between the end and the ground after tilting is small, so it is easy to cut into the ground and cause direct collision, thereby reducing the service life of the blade.

[0012] Preferably, the internal lower cavity of the sleeve is provided with oil, and the sleeve is connected with the internal upper part of the first oil chamber through a connecting pipe, and the first oil chamber is symmetrically fixed to the top of the tool holder, and the top of the first oil chamber is slidably connected with a first piston plate, and the first piston plate is symmetrically fixed to the bottom of the mounting plate.

[0013] Preferably, the length adjustment component includes a cavity opened inside the tool holder, and the output end of the motor in the middle of the cavity is connected to the first screw, and the outer thread of the first screw is connected to the movable plate, and the movable plate and the cavity are both arranged as rectangular structures, and the movable plate forms a vertical sliding structure through the first screw.

[0014] Preferably, a toothed plate is fixed in the middle of the four sides of the bottom of the movable plate, and the outer side of the toothed plate is meshed with the adjusting gear, and the adjusting gear is connected to the inside of the cavity with angular bearings thereof, and a second screw is integrally installed in the middle of the adjusting gear, and the second screw rotates synchronously with the adjusting gear.

[0015] Preferably, the outer side of the second screw is threadedly connected with a sleeve rod, and the sleeve rod is arranged in a rectangular shape, and the sleeve rod penetrates and is slidably connected to the periphery of the tool holder, and the blade forms a length adjustment structure through the sleeve rod.

[0019] Compared with the prior art, the beneficial effects of the device for cleaning the sedge vine for landscaping in complex areas of the present invention are: when in use, when passing through the corners of uneven terrain, the blade is protected by the avoidance component to avoid cutting into the ground and causing damage, and in actual cleaning work, the corresponding cleaning components may need to be adjusted according to the distribution density of the sedge vine, thereby improving the flexibility of the device in different cleaning scenarios. The specific contents are as follows:

[0020] 1. By setting up the avoidance component, when the device passes through the turning point of the uneven position, when the machine body drives the blade to climb or go downhill, in the process of the blade from being parallel to the ground to forming an angle with the ground, the resistance rod enters the vertex of the triangle formed between the machine body and the ground, extends from the sleeve, and fits and contacts with the turning point of the uneven position, squeezes out the oil in the sleeve, and injects it into the first oil chamber. After the oil in the first oil chamber increases, the first oil chamber moves upward and slides outside the first piston rod, thereby driving the tool holder as a whole to drive the blade upward, so that there is an avoidance space between the blade and the ground, avoiding that when climbing or going downhill through the triangular area, the distance between the blade and the ground is too small, causing the end of the blade to cut into the ground and cause damage to the blade;

[0021] 2. Through the length adjustment component, when cleaning the sedge with different growth densities, the motor drives the first screw to rotate, and the moving plate moves down, driving the tooth plate to move down synchronously. After the tooth plate moves down, it meshes with the adjustment gear, and the adjustment gear drives the second screw to rotate synchronously. After the second screw rotates, the sleeve rod extends from the periphery of the knife holder, thereby extending the use length of the blade and expanding the cutting range. When cleaning the sedge with a relatively dense distribution and a large area, the cleaning efficiency can be improved;

[0022] 3. Through the position adjustment component, after the blade length is adjusted, the corresponding avoidance node also needs to be advanced, and then the moving plate moves down to drive the piston frame to move down synchronously in the hollow ring, and then the oil is squeezed out. The oil is transported to the second oil chamber in the transverse groove through the connecting pipe, and the second piston plate on the second oil chamber extends. After the second piston plate extends, it pushes the sleeve to move, changing the contact node of the resistance rod and the inflection point, so that the blade moves up to avoid in time;

[0023] 4. By setting up the expansion component, after the cleaning range is adjusted, the size of the collection port of the cover also needs to be adjusted accordingly, so that the cut chicken shit vine can be collected and processed in a centralized manner. Part of the oil in the hollow ring enters the sliding sleeve through the connecting pipe, and the sliding sleeve slides along the sliding rod, thereby driving the slider to move in the sliding groove, and unfolding the rotating plate on the cover, so as to better collect the cleaned chicken shit vine.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0036] See also Figure 1 - Fig.10 As shown, the present invention provides a technical solution: a device for cleaning sedge for landscaping in complex areas, comprising a machine body 1, and tracks 2 for coping with complex terrain are installed at the bottom of the front and rear sides of the machine body 1, and a mounting plate 3 is arranged at the bottom of the machine body 1, and a shaft 4 is fixed in the middle of the top surface of the mounting plate 3, and the shaft 4 passes through the bearing and is connected to the inner side of the bottom of the machine body 1, and the top of the shaft 4 is connected to the output end of the motor inside the machine body 1 through a group of driving gears 5, and a knife holder 6 is arranged at the bottom of the mounting plate 3, and blades 7 are arranged at equal angles around the knife holder 6, a crushing chamber 8 is opened on the inner side of the bottom of the machine body 1, and a conveyor belt 9 is arranged at the entrance of the crushing chamber 8, and a crushing roller 10 is installed in the middle of the inner side of the crushing chamber 8, and a cover shell 11 is installed at the bottom of the machine body 1, and the cover shell 11 is half-wrapped on the outside of the blade 7;

[0037] First, the basic weeding process of the device is introduced. The machine body 1 walks in the garden with complex terrain through the crawler 2. The motor drives the shaft 4 to rotate through the driving gear 5. The shaft 4 drives the mounting plate 3 and the knife holder 6 below to rotate synchronously. The knife holder 6 drives the blade 7 to rotate to remove the chicken shit vine in the garden. After the blade 7 rotates, the rhizome of the chicken shit vine is cut off. The cover 11 collects the cut chicken shit vine branches, which are then collected into the crushing chamber 8 by the conveyor belt 9. The crushing roller 10 in the crushing chamber 8 crushes the chicken shit vine;

[0038] Embodiment 1: To solve the problem that the blade 7 is easily damaged by cutting into the ground at the corner when the cleaning device passes through an uneven position, the following solution is proposed. Please refer to Figure 1 - Figure 6 As shown;

[0039] The avoidance component 12 is arranged at the bottom of the front side of the machine body 1 and between the mounting plate 3 and the blade holder 6. The avoidance component 12 avoids and protects the blade 7 when the device travels on an uneven section to avoid damage. The avoidance component 12 includes a sleeve 121, and the sleeve 121 is slidably connected to the bottom of the front side of the machine body 1. A resistance rod 122 is slidably connected through the bottom of the sleeve 121, and a ball is arranged at the bottom of the resistance rod 122. At the same time, the bottom of the resistance rod 122 contacts the ground;

[0040] When in use, when the machine body 1 moves over an uneven position and passes a turning point, the abutment rod 122 at the bottom of the machine body 1 enters the vertex of the triangle formed between the machine body 1 and the ground, extends from the sleeve 121, and fits and abuts against the turning point of the uneven position, squeezing out the oil in the sleeve 121;

[0041] Specifically, the lower cavity inside the sleeve 121 is provided with oil, and the sleeve 121 is connected to the upper part of the inner part of the first oil chamber 124 through a connecting pipe, and the first oil chamber 124 is symmetrically fixed to the top of the tool holder 6, and the top of the first oil chamber 124 is slidably connected with the first piston plate 123, and the first piston plate 123 is symmetrically fixed to the bottom of the mounting plate 3;

[0042] When in use, the oil in the sleeve 121 is injected into the first oil chamber 124 through the connecting pipe. After the oil in the first oil chamber 124 increases, the first oil chamber 124 slides upward outside the first piston plate 123, thereby driving the tool holder 6 as a whole to drive the blade 7 upward, so that there is a avoidance space between the blade 7 and the ground, to avoid the end of the blade 7 cutting into the ground and causing damage to the blade 7 when climbing or descending through the triangular area.

[0043] Embodiment 2: When cleaning the different growth densities of the spatholobi, the cleaning range of the cleaning component is adaptively adjusted to achieve a better cleaning effect and higher cleaning efficiency. Therefore, the following solution is proposed. Please refer to Figure 6 - Figure 8 As shown;

[0044] The length adjustment component 13 is arranged inside the knife holder 6, and the length adjustment component 13 adjusts the cutting range according to the distribution density of the sedge vine to improve the cleaning efficiency. The length adjustment component 13 includes a cavity 131 opened inside the knife holder 6, and the output end of the motor in the middle of the cavity 131 is connected to the first screw 132, and the outer side of the first screw 132 is threadedly connected to the moving plate 133, and the moving plate 133 and the cavity 131 are both set to a rectangular structure, and the moving plate 133 forms a vertical sliding structure through the first screw 132;

[0045] When in use, when the density of the distribution of the spatholobiaceae is different, it is necessary to adjust the cutting length of the blade 7. At this time, the motor in the cavity 131 is started, and the motor drives the first screw 132 to rotate, and the moving plate 133 moves downward;

[0046] Specifically, a tooth plate 134 is fixed to the middle of the four sides of the bottom of the movable plate 133, and the outer side of the tooth plate 134 is meshed with the adjusting gear 135, and the adjusting gear 135 is angularly bearing-connected to the inside of the cavity 131, and a second screw rod 136 is integrally installed in the middle of the adjusting gear 135, and the second screw rod 136 rotates synchronously with the adjusting gear 135, and the outer side of the second screw rod 136 is threadedly connected with a sleeve rod 137, and the sleeve rod 137 is set to a rectangular shape, and the sleeve rod 137 penetrates and is slidably connected to the four sides of the tool holder 6, and the blade 7 forms a length adjustment structure through the sleeve rod 137;

[0047] When in use, the movable plate 133 moves downward, driving the tooth plate 134 to move downward synchronously. After the tooth plate 134 moves downward, it meshes with the adjusting gear 135. The adjusting gear 135 drives the second screw 136 to rotate synchronously. After the second screw 136 rotates, the sleeve rod 137 extends from the four sides of the knife holder 6, thereby extending the use length of the blade 7 and expanding the cutting range. When cleaning the densely distributed and large-area chicken shit vines, the cleaning efficiency can be improved.

[0048] Embodiment 3: After the cleaning range is expanded, the blade 7 is further protected to prevent the blade from hitting the ground. Therefore, the following solution is proposed. Please refer to Figure 3 - Figure 6 As shown;

[0049] A displacement adjustment component 14, which is arranged at the front bottom of the body 1 and inside the tool holder 6, and the displacement adjustment component 14 adjusts the avoidance node according to the use length of the blade 7. The displacement adjustment component 14 includes a hollow circular ring 141 fixed to the top of the inner side of the cavity 131 and filled with oil, and the bottom of the hollow circular ring 141 is penetrated by a piston rack 142 in sliding connection, and the top of the piston rack 142 is set as a circular ring plate, and two vertical plates are installed at the bottom, and the hollow circular ring 141 is connected to the second oil chamber 144 in the transverse groove 143 through a connecting pipe, and the transverse groove 143 is opened at the front bottom of the body 1, and the sleeve 121 is slidably connected in the transverse groove 143, and the left end of the second oil chamber 144 is slidably connected to the second piston plate 145, and the end of the second piston plate 145 is fixedly connected to the top side of the sleeve 121;

[0050] After the length of the blade 7 is adjusted, when passing through the turning point of the uneven position, it is necessary to change the time point when the blade 7 starts to avoid. After the movable plate 133 moves downward, it drives the piston frame 142 to move downward synchronously in the hollow ring 141, and then squeezes out the oil. The oil is transported to the second oil chamber 144 in the transverse groove 143 through the connecting pipe, and the second piston plate 145 on the second oil chamber 144 extends. After the second piston plate 145 is extended, it pushes the sleeve 121 to move, thereby changing the node where the resistance rod 122 contacts the turning point, so that the blade 7 moves up and avoids in time.

[0051] Embodiment 4: During the use of the cleaning device, the cut sedge is crushed, the cleaning range is expanded, and then the corresponding collection opening is expanded to obtain a better collection effect. Therefore, the following scheme is proposed. Please refer to Figure 1 - Figure 5 and Fig. 9 - Fig.10 As shown;

[0052] An extension component 15 is arranged at the front and rear sides of the housing 11, and the extension component 15 adjusts the extension range according to the use length of the blade 7 to collect the cut sedge vines. The extension component 15 includes a rotating plate 151 hingedly connected to the front and rear sides of the housing 11, and a sliding groove 152 is transversely opened on the outer side of the rotating plate 151, and a slider 153 is slidably connected in the sliding groove 152, a sliding sleeve 154 is hinged on the outer side of the slider 153, and a sliding rod 155 is slidably connected in the middle of the sliding sleeve 154, and the outer side of the sliding rod 155 is hinged to the bottom of the body 1, and the sliding sleeve 154 has built-in oil;

[0053] When in use, after the cutting range of the blade 7 is increased, the size of the collection opening of the cover shell 11 for the cut Cistanche deserticola should also be adjusted accordingly. A part of the oil in the hollow ring 141 enters the sliding sleeve 154 through the connecting pipe. The sliding sleeve 154 slides along the sliding rod 155, thereby driving the slider 153 to move in the sliding groove 152, and unfolding the rotating plate 151 on the cover shell 11, so as to better collect the cleaned Cistanche deserticola.
