[Technical field to which the invention belongs]

 The present invention is a so-called sand cleaner, and it is a danger of dirt such as dog and cat excrement in sandboxes installed in parks, nurseries, schools, empty cans, plastic, glass shards, stones, garbage, etc. The present invention relates to a sandbox cleaner that is suitable for cleaning things and cleaning the sandbox cleanly.

[0002]

[Prior art]

 At present, bacteria and roundworm contamination caused by sewage of dogs and cats in the sandboxes installed in parks, nurseries, schools, etc. are becoming a major social problem in terms of environmental hygiene, especially when they enter the human body. A large number of Toxocara nematode eggs and pests, which are roundworm eggs of dogs and cats that cause fever, muscle aches, nutritional disorders, and visual impairments, were found in sandboxes in parks, nurseries, schools, etc. There was a problem that we could not play with peace of mind because there were dangerous materials such as plastics, broken glass, stones, and dust. For this reason, until now, machines for cleaning, sterilizing, and disinfecting sandboxes have adopted a method in which sterilization and disinfection is performed with a disinfectant solution or a flame method, and moreover, the sand is taken out once from the sandbox. Also, a beach cleaner in which dust on the beach of a beach or the like is scooped up together with sand and the dust is collected in a container while sieving off the sand with a comb conveyor (for example, Japanese Patent Laid-Open No. 2-153104).

[0003]

[Problems to be solved by the device]

 However, the former former is one in which the machine is large and sand is once taken out from the sandbox, while the latter is sterilized and disinfected by the disinfectant solution or the flame method, while the latter conventional one is used in the beach or the like. Since they are beach cleaners that clean the beaches, they were not easy to use, and not only could they be used in small sandboxes, but they could not be used by weak women. In addition, the large size of the machine and the troublesome work combined with the disadvantage that the cost of cleaning the sandbox is extremely high. In addition, the latter beech cleaner only collects trash on the beach and was not suitable for sandboxes such as parks, nursery schools and schools that require sterilization.

Therefore, the problem to be solved by the present invention was devised in view of the above-mentioned viewpoints, and it is possible to use it not only in a large sandbox but also in a small sandbox in view of downsizing and easiness of work. Not only can it be used, but it can also be used by lame women, and the cost of cleaning sandboxes can be significantly reduced, and an optimal sandbox cleaner for parks, nurseries, schools, etc. must be provided. It is in.

As shown in FIG. 1 and FIG. 2, the sandbox cleaning machine of the present invention is a two-wheeled self-propelled vehicle body 1 for excavating sand, dirt, dangerous substances, etc. in a sandbox by upcutting. The rotor 3 is wider than the space between the wheels 2 on the left and right, and the rotor 3 is rotated to sterilize and disinfect the sand, dirt, and dangerous materials excavated, and part of the sand. Conveyor 4 with a mesh structure that conveys to the rear while shaking off the sand, and further shakes the sand from the sand, dirt, dangerous materials, etc. conveyed by this conveyor 4 to collect the remaining dirt, dangerous materials, etc. And a net-shaped swing box 5 to be thrown away to another place, and one or more small height-adjustable small units that adjust the depth of excavation of sand, dirt, dangerous materials, etc. by the rotor 3. The front wheel 6 is provided.

That is, the present machine is a two-wheel self-propelled type, and the traveling part by the left and right wheels 2 on the rear side and the rotor part by the rotor 3 are provided with clutches that operate separately, When traveling the traveling part, the traveling clutch lever 8b attached to the right handle 7 is operated to travel through the traveling part tension clutch 9. On the other hand, when traveling the rotor part, the left steering wheel is used. 7, the rotor clutch lever 8a is operated to change the rotation speed from the travel speed through the rotor tension clutch 10 and the counter gear in the counter gear case 11, and the wheels of the travel speed are changed. Run so as to rotate in the opposite direction to 2. In this case, when cleaning the sandbox, it is adjustable up and down so that the operator can work in a comfortable posture. In the figure, reference numeral 12 is an engine, and reference numeral 13 is a mission case.

The rotor 3 is wider than the space between the left and right wheels 2 of the vehicle body 1 and rotatable, and has a plurality of sand scraping claws 14 each having a substantially V-shaped front surface on the outer peripheral surface. It is formed so as to be removably attached to the L-shaped attachment plate 15 via screwing means 16 and the like, arranged at appropriate intervals in the direction. The clear lance driving chain case 17 and the rotor 3 are supported on the vehicle body 1 so as to be vertically swingable.

On the upper side of the rotor 3, rotor covers 18 are arranged at appropriate intervals so that sand, dirt, dangerous substances, etc. excavated by rotating the rotor 3 are smoothly guided and placed on the conveyor 4. At the front end of the rotor cover 18, a rubber scattering prevention plate 19 that prevents sand, dirt, dangerous substances, etc. from scattering forward is attached via a retaining metal fitting 20.

[0015]

[Effect of the invention]

 As described above, the sandbox cleaning machine of the present invention digs up sand, dirt, dangerous materials, etc. in the sandbox by the upcut on the two-wheel self-propelled vehicle body 1, and the space between the left and right wheels 2 of the vehicle body 1 described above. A wider rotatable rotor 3 and the rotor 3 is rotated to sterilize and disinfect sand, dirt, and dangerous materials excavated, and shake off part of the sand to the rear. The conveyor 4 having a mesh structure to be transported to and the sand, filth, dangerous substances, etc. conveyed by this conveyor 4 are further shaken off the sand, and the residual filth, dangerous substances, etc. are collected and stored in another place. Since the shaking box 5 having a mesh structure to be discarded and one or a plurality of small front wheels 6 whose height is adjustable for adjusting the depth of excavation of sand, dirt, dangerous materials, etc. by the rotor 3 are provided, When cleaning the sandbox, rotate the rotor 3 while the machine is running. Sand, dirt, dangerous materials, etc. in the sandbox are dug up by upcut and placed on the conveyor 4, and while sand, dirt, dangerous materials, etc. are sterilized and detoxified on the conveyor 4, part of the sand is shaken. While being dropped off, it is transported backwards into the shake box 5, and here, the sand is further shaken off from the sand, dirt, dangerous materials, etc. Since it is only necessary to dispose of this filth, dangerous materials, etc. to another place, the work can be facilitated, and the two-wheeled self-propelled car body 1 has the rotor 3, the conveyor 4, the swing box 5, and the small front wheel 6. Since it only needs to be equipped with such equipment, it can be used in a small sandbox as well as a large sandbox, and it can be used not only by lame women but also by the cost of cleaning sandboxes. Can be significantly cheaper.

Moreover, by making the rotor 3 wider than the space between the left and right wheels 2 of the vehicle body 1, the space between the left and right wheels 2 running rearward is narrower than the width of the rotor 3 running forward. Since one wheel does not run on the uncleaned part (uncultivated land), it is possible to prevent the machine from losing its balance, and the height of the small front wheel 6 is adjustable so that the rotor 3 Combined with the fact that the depth of excavation of sand, dirt, dangerous materials, etc. can be adjusted arbitrarily, workability can be further enhanced.

Further, above the rotor 3, a rotor cover 18 for smoothly guiding and placing sand, dirt, dangerous substances, etc. excavated by rotating the rotor 3 on the conveyor 4 is arranged at appropriate intervals. At the front end of the rotor cover 18, a scatter preventive plate 19 for preventing sand, dirt, dangerous substances, etc. from scattering forward is vertically installed so that the sand and dirt caused by the rotor 3 can be adjusted. Not only can sand, dirt, and dangerous materials be prevented from scattering forward and upward regardless of the depth of excavation of dangerous materials, but also sand excavated by rotating the rotor 3 can be prevented. It is possible to smoothly guide and place dirt, dangerous substances, etc. on the conveyor 4.

In addition, since the clear lance drive chain case 17 and the rotor 3 are swingably supported on the vehicle body 1 in the vertical direction, the rotor 3 can be fixed at the upper part, which is an obstacle to running. This makes it easy to drive the machine on the road. Further, since several sand scraping pawls 14 are arranged on the outer peripheral surface of the rotor 3 at appropriate intervals in the outer peripheral direction and are detachably attached, the worn sand scraping pawls 14 can be easily replaced and the sand scraping pawls 14 can be brushed. It can also be used for cleaning by replacing it with. Furthermore, since each sand scraping claw 14 is formed in a substantially V-shaped front shape, it is possible to prevent the sand, dirt, dangerous materials, etc. from scattering in the left and right directions. It can be reliably placed on the center of 4.

Further, since the rotor 3 is rotated to dig up sand, dirt, dangerous substances, etc. excavated and sterilized and disinfected on the conveyor 4, it is most suitable for sandboxes such as parks, nurseries and schools.
