Description

Technical Field

[0001] The present invention relates to the technical field of municipal curb maintenance and management, and more particularly to a weeding and cleaning device and a cleaning method for municipal curb stone crevices. Background Art

[0002] Greening maintenance for municipal curbs refers to the later watering, pruning, weeding, spraying, and seedling replacement after the greening construction is completed. This work is collectively referred to as maintenance. The work is simple but indispensable. If the maintenance work is not done well, the garden landscape built at a great cost cannot be well maintained. Some will quickly experience grass degradation, tree death, and overgrown weeds. Therefore, landscape maintenance must implement standardized municipal curb maintenance management. In addition, greening maintenance refers to the management and maintenance of green spaces, vegetation and other plants. Due to the particularity of the industry, the main contents of greening maintenance include: watering, fertilizing, pruning, weeding, green space cleaning and sanitation, pest and disease control, waterlogging and drought prevention, etc.; in the process of municipal construction, weeds often grow in the cracks of the stones of municipal curbs, so sanitation workers are needed to remove them to achieve the effect of standardized municipal curb maintenance management.

[0003] In the process of weeding in the cracks of municipal curbstones, hard tools such as spike rakes are usually used to remove weeds by scraping. However, this scraping method, due to the large resistance of the hard tool, will cause the weeding end of the hard tool to get stuck or break. At the same time, this weeding method is inefficient and consumes a lot of physical energy for workers, so it is not conducive to practical use. Summary of the Invention

[0024] In a preferred embodiment, a cleaning method for a municipal curbstone weeding and cleaning device:

[0025] S1: Move the stone crevice weeding end and the weeding rod to the position where weeding is to be done, and drag the stone crevice weeding end and the weeding rod to perform drag weeding by dragging the main traction arm;

[0026] S2: The main traction arm has two weeding modes during the drag weeding process. In the first weeding mode, the angle between the main traction arm and the ground is 10°-30°; in the second weeding mode, the angle between the main traction arm and the ground is 60°-80°.

[0027] S3: In the first weeding mode, the spiral weeding section rotates with the weeds through the contact between the roller and the ground. Since the crevice weeding end contacts the ground, the crevice weeding end maintains a dragging weeding mode.

[0028] S4: In the second weeding mode, the spiral weeding section rotates with the weeds through the contact between the roller and the ground. Since the crevice weeding end does not touch the ground, it remains suspended in the air.

[0029] S5: Before weeding, inject the liquid medicine into the injection pipe according to the soil conditions, and squeeze the airbag grip to allow the liquid medicine to be injected into the liquid outlet 1 and liquid outlet 2 to complete the stone crevice injection process.

[0030] The technical effects and advantages of the present invention are as follows:

[0031] The main traction arm drags the roller to drive the bevel gear 2 to rotate. Since the bevel gear 2 and the bevel gear 1 maintain a spiral gear transmission relationship, the spiral weeding section forms a spiral weeding operation during the rotation, which makes the sanitation workers more labor-saving during the weeding process.

[0032] Liquid is injected into the main traction arm through the injection pipe, and the airbag grip is squeezed to achieve active liquid injection, which improves the convenience of weeding and maintenance management in stone crevices.

[0033] After the second angle adjustment of the spherical universal joint is completed, the stone crevice weeding end head will be deformed due to dragging, and the first adjusting arm pushes the positioning sleeve to slide on the outer wall of the extended traction arm. On the one hand, it forms a buffering effect on the stone crevice weeding end head, reducing the probability of its breakage. On the other hand, when the positioning sleeve pushes the spiral buffer section, the gas in the spiral buffer section squeezes the liquid medicine in the extended traction arm. As a result, the resistance of the stone crevice weeding end head is greater, the stone crevice is relatively larger, and more liquid medicine is injected, thereby improving the convenience of use.

[0034] The two-angle weeding mode improves the convenience and controllability of stone crevice injection and stone crevice weeding. BRIEF DESCRIPTION OF THE DRAWINGS

Implementation Method

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0046] Refer to the instruction manual Figure 1-9 In one embodiment of the present invention, a device for cleaning and weeding stone crevices of municipal curbs comprises a main frame mechanism 1, one end of which is mounted a grip adjustment mechanism 2 for a sanitation worker to operate the device, and an end of the main frame mechanism 1 away from the grip adjustment mechanism 2 is mounted with a first stone crevices weeding mechanism 3 and a second stone crevices weeding mechanism 4 for removing weeds from the stone crevices.

[0047] like Figure 6-9As shown, the stone crevice weeding mechanism 2 4 includes an external positioning frame 41, which is installed in the middle of the main frame mechanism 1 through a pin or bolt. The external positioning frame 41 is equidistantly installed with a plurality of central bearings 42 at a position away from the main frame mechanism 1. The inner cavity of the central bearing 42 is rotatably connected to the first transmission roller 43, and the outer wall of the first transmission roller 43 is fixedly installed with a support base 44. The outside of the support base 44 is fixedly installed with a bevel gear 1 45. The outer wall of the first transmission roller 43 is installed with a positioning bearing section 1 46, and the bottom of the positioning bearing section 1 46 is fixedly installed with a hydraulic rod 47. The bottom of the hydraulic rod 47 is fixedly installed with a positioning bearing section 2 48. The center position of the positioning bearing section 2 48 is rotatably connected to the second transmission roller 49, and the outer wall of the second transmission roller 49 is fixedly installed with a bevel gear 2 410. The bevel gear 2 410 and the bevel gear 1 45 are meshed with each other.

[0048] In addition, rollers 411 are fixedly installed at both ends of the second transmission roller 49, and a weeding rod 413 for weeding is installed at one end of the roller 411; a third transmission roller 412 is fixedly installed at one end of the first transmission roller 43, and the third transmission roller 412 is arranged on one side of the positioning bearing section 46, and the third transmission roller 412 is fixedly connected to the weeding rod 413; a spiral weeding section 414 is wrapped around the outer wall of the weeding rod 413, and the end cross-sectional diameter of the spiral weeding section 414 is smaller than the tail cross-sectional diameter thereof, and the end of the spiral weeding section 414 is used to contact the stone crevice first; in addition, the positions of the external positioning frame 41, the first transmission roller 43 and the third transmission roller 412 are arranged in a one-to-one correspondence along a straight line, and the third transmission roller 412 and the external positioning frame 41 are kept perpendicular to each other.

[0049] like Figure 8 As shown, spherical anti-stuck end heads 415 are fixedly installed at both ends of the spiral weeding section 414 . The spherical anti-stuck end heads 415 are made of spherical stainless steel material and are fixedly installed on the outer wall of the third transmission roller 412 .

[0050] It needs to be further explained that: in actual use, the roller 411 slides on the ground through the dragging of the main traction arm 101, and the roller 411 drives the bevel gear 2 410 to rotate. Since the bevel gear 2 410 maintains a spiral gear transmission relationship with the bevel gear 1 45, the bevel gear 2 410 rotates, and the spiral weeding section 414 forms a spiral weeding operation during the rotation, which saves sanitation workers more effort in the weeding process.

[0051] In a further solution of Example 1, the stone crevice weeding mechanism 1 3 includes a first positioning ring 31, the first positioning ring 31 is fixedly mounted on the outer wall of the main frame mechanism 1, an extended traction arm 32 is fixedly mounted on the inner wall of the first positioning ring 31, and the extended traction arm 32 is fixedly connected to the main frame mechanism 1, and a plurality of buffer-type support arms 33 are installed in a circular shape and equidistantly in sequence on the outer wall of the first positioning ring 31, and a second positioning ring 34 is fixedly mounted on one end of the plurality of buffer-type support arms 33, and the second positioning ring 34 is sleeved on the outside of the extended traction arm 32, and a spiral buffer section 35 is installed on the outer wall of the extended traction arm 32, and the top end of the spiral buffer section 35 is fixedly connected to the extended traction arm 32, and the rest of the spiral buffer section 35 is slidably sleeved on the outside of the extended traction arm 32;

[0052] A positioning sleeve 36 is slidably connected to the outside of the extended traction arm 32. The positioning sleeve 36 is arranged on the side of the spiral buffer section 35 away from the buffer support arm 33. A damping sleeve 37 is slidably connected to the outside of the positioning sleeve 36. Anti-falling support ends 38 are fixedly installed at both ends of the positioning sleeve 36. A first adjusting arm 39 is fixedly installed on the outer wall of the damping sleeve 37. A spherical universal joint part 310 is installed at one end of the first adjusting arm 39. One end of the arm 39 is hinged to a second adjustment arm 311 through a spherical universal joint part 1 310, and one end of the second adjustment arm 311 is installed with a spherical universal joint part 2 312. One end of the second adjustment arm 311 is hinged to a third adjustment arm 313 through a spherical universal joint part 2 312. One end of the third adjustment arm 313 is fixedly installed with a movable pipe sleeve 314. One end of the extension traction arm 32 is fixedly installed with a stone crevice weeding end 316 for weeding. In addition, the stone crevice weeding end When the spherical universal joint 312 is adjusted, the stone crevice weeding end 316 will be deformed by the drag, so that the movable sleeve 314 slides on the outer wall of the stone crevice weeding end 316, and the first adjusting arm 39 pushes the positioning sleeve 36 to slide on the outer wall of the extension traction arm 32, which forms a buffering effect on the stone crevice weeding end 316 and reduces the possibility of its breakage. rate, the movable sleeve 314 is slidably connected to the outside of the stone crevice weeding end 316; in addition, a locking portion is provided on the outside of the spherical universal joint part 312, and the spherical universal joint part 1 310 is a universal connection part. A damping airbag section 315 is fixedly installed on the top of the movable sleeve 314, and the damping airbag section 315 is sleeved on the outside of the stone crevice weeding end 316. The damping airbag section 315 is a hollow structure, and the inner cavity of the damping airbag section 315 is filled with gas.

[0053] It should be further explained that, during the dragging process of the main traction arm 101, the stone crevice weeding end 316 contacts the ground, and the stone crevice weeding end 316 forms a dragging and weeding effect on the stone crevice. After the angle adjustment of the spherical universal joint part 312 is completed, the stone crevice weeding end 316 will be deformed due to the dragging, so that the movable sleeve 314 slides on the outer wall of the stone crevice weeding end 316, and the first adjustment arm 39 pushes the positioning sleeve 36 to slide on the outer wall of the extension traction arm 32, which on the one hand 6 forms a buffering effect, reducing the probability of its breakage. On the other hand, the positioning sleeve 36 squeezes the spiral buffer section 35. The spiral buffer section 35 is also hollow in structure. The end of the spiral buffer section 35 is connected to the extended traction arm 32. When the positioning sleeve 36 pushes the spiral buffer section 35, the gas in the spiral buffer section 35 squeezes the liquid medicine in the extended traction arm 32. As a result, the greater the resistance of the crevice weeding end 316, the larger the crevice is, and the more liquid medicine is injected, which improves the convenience of use.

[0054] In addition, during the injection process, there are two ideas for injection. One is anti-root rot and fungicide drugs composed of metalaxyl, carbendazim and carbendazim, and the other is herbicide drugs.

[0055] In a further solution for weeding and injecting medicine, a plug-type plugging head 102 is sealed and plugged into one end of the main traction arm 101, and an air intake one-way valve 103 is installed at a position close to the plug-type plugging head 102 of the main traction arm 101; the main traction arm 101 is arranged in a hollow pipe structure, and the middle part of the main traction arm 101 is connected to a liquid injection pipe part 104, which is used to inject liquid medicine, and the end of the liquid injection pipe part 104 is threadedly connected to a cover, and the grip adjustment mechanism 2 includes an air bag The airbag gripping portion 21 is provided with a bolt-type plugging head 22 installed at both ends of the airbag gripping portion 21. A stainless steel pipe arm 23 is fixedly installed at both ends of the airbag gripping portion 21 through the bolt-type plugging head 22. A three-way connector 24 is installed at one end of the stainless steel pipe arm 23 away from the airbag gripping portion 21. The three-way connector 24 is connected to the main traction arm 101; the airbag gripping portion 21, the stainless steel pipe arm 23 and the three-way connector 24 are connected; a one-way valve is installed at the position of the airbag gripping portion 21;

[0056] In addition, the extended traction arm 32 and the crevice weeding end 316 are arranged in a hollow pipe structure, the main traction arm 101, the extended traction arm 32 and the crevice weeding end 316 are connected, the bottom end of the crevice weeding end 316 is provided with a liquid outlet 1, the external positioning frame 41, the first transmission roller 43, the third transmission roller 412, the weeding rod 413 and the spherical anti-stuck end 415 are arranged in a hollow pipe structure, and the spherical anti-stuck end 415 near the end of the spiral weeding section 414 is provided with a liquid outlet 2.

[0057] It should be noted that liquid is injected into the main traction arm 101 through the injection pipe part 104, and the airbag gripping part 21 is pinched to form the effect of active injection. The function of the air intake one-way valve 103 is to prevent the liquid from being infused into the airbag gripping part 21 and causing corrosion to it. The one-way valve of the airbag gripping part 21 is to allow the airbag gripping part 21 to push the liquid flow to the main traction arm 101 by air pressure after pinching, and it can also take in air, thereby achieving the effect of reciprocating operation.

[0058] A cleaning method for a municipal curbstone crack weeding and cleaning device,

[0059] S1: Move the stone crevice weeding terminal 316 and the weeding rod 413 to the position where weeding is to be done, and drag the main traction arm 101 so that the stone crevice weeding terminal 316 and the weeding rod 413 are dragged to do weeding;

[0060] S2: The main traction arm 101 has two weeding modes during the drag weeding process. In the first weeding mode, the angle between the main traction arm 101 and the ground is 10°-30°; in the second weeding mode, the angle between the main traction arm 101 and the ground is 60°-80°.

[0061] S3: In the first weeding mode, the spiral weeding section 414 rotates with the weeds due to the contact between the roller 411 and the ground, and the crevice weeding end 316 maintains a dragging weeding mode because it is in contact with the ground.

[0062] S4: In the second weeding mode, the spiral weeding section 414 rotates with the weeds by the contact between the roller 411 and the ground, and the crevice weeding end 316 remains suspended in the air because the crevice weeding end 316 does not contact the ground.

[0063] S5: Before weeding, according to the soil conditions, inject the liquid medicine into the liquid injection pipe part 104, and squeeze the airbag grip part 21 to allow the liquid medicine to be injected into the liquid outlet 1 and the liquid outlet 2 to complete the stone crevice injection process.

[0064] What needs to be further explained about the cleaning method is that when the angle between the main traction arm 101 and the ground is 10°-30°, that is, the double weeding process, the spiral weeding section 414 performs rotational weeding, and the crevice weeding end 316 performs scraping weeding. When the angle between the main traction arm 101 and the ground is 60°-80°, since the crevice weeding end 316 cannot contact the ground, unilateral spiral weeding can be performed, thereby improving the convenience and controllability of the device.

[0065] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection.
