Description

Technical Field

[0001] The invention relates to the technical field of greening planting, and in particular to a greening waste composting and fertilizing device. Background Art

[0002] In order to enhance the greening landscape effect, my country's road greening generally adopts the planting method of dense planting of seedlings, densely planting hedges and shrubs from the inside to the outside, forming a green belt with multiple rows of dense planting, clear layers and diverse landscapes. Although dense planting of seedlings can quickly produce green space effects and improve the urban ecological environment, dense planting of seedlings in a relatively fixed space increases the plants' demand for soil nutrients and water, resulting in soil impoverishment, which requires continuous addition of organic matter to repair and fertilize the soil.

[0003] Landscaping waste, mainly tree and shrub prunings produced during greening maintenance, can be turned into good organic fertilizer after crushing and composting. It can not only be used to improve the soil and plant growth environment, but also solve the problem of urban landscaping waste disposal. Returning fallen leaves to the earth is a better destination for fallen leaves. In order to save costs and make the active microorganisms in the compost play a better role, organic fertilizers produced from greening waste are generally not granulated like chemical fertilizers, which brings a series of problems such as poor operation of artificial fertilization, dust pollution, inconvenience of mechanized fertilization, poor appearance of fertilizer products, and affecting sales prices.

[0004] During the process of green plant maintenance and fertilization, maintenance workers usually spread fertilizers directly on the green plants. In densely planted green belts, chemical fertilizers can be easily and evenly spread on the ground due to granulation. However, since green waste compost is in the form of granules and powder, this fertilization method often causes most of the fertilizer to fall on the branches and trunks of the plants, resulting in fertilizer loss and waste. At the same time, it will produce a lot of dust, which not only pollutes the surrounding environment, but is also not good for the health of maintenance workers. Summary of the invention

[0005] The purpose of the present invention is to solve the above-mentioned problems and to propose a greening waste composting and fertilizing device.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

The negative pressure device can be connected to an external power source, or directly powered by a battery; the driving device is a conventional motor or a servo motor.

[0036] The end of the feeding pipe 2 away from the driving member 4 is fixed to the outside of the cylinder 6, and the feeding pipe 2 is connected to the inside of the cylinder 6. The suction pipe 18 extends from the negative pressure device 7 to the bottom of the cylinder 6, and has a spacing of 50-80 mm from the inner lower end surface of the cylinder 6. The inner lower end surface of the cylinder 6 is a funnel-shaped structure, so that the fertilizer can move to the bottom of the suction pipe 18, and at the same time, the suction pipe 18 is easier to suck.

[0037] The outer side of the telescopic piece 10 is fixedly connected with a connecting plate 11, and a penetrating pin 12 is inserted into the connecting plate 11. The outer side of the handle 9 is sleeved with a collar 13, and the pin 12 is inserted into the lower end of the collar 13. The telescopic piece 10 is connected to the collar 13 through the pin 12 and can be disassembled at the same time.

[0038] At least one magnetic block 17 is disposed on the end surface of the open side of the expansion piece 10. The magnetic block 17 on one expansion piece 10 protrudes from the end surface, and the magnetic block 17 on the other expansion piece 10 is recessed inward, thereby keeping the end surfaces of the open sides of the two expansion pieces 10 in contact with each other.

[0039] The inner wall of the lower hopper 3 is provided with a plurality of annular evenly distributed air holes 19, and the interior of the lower hopper 3 is provided with an annular air groove 20, and the plurality of air holes 19 are all connected to the air groove 20, and the air groove 20 is connected to the negative pressure device 7 through an air pipe. After the negative pressure device 7 is started, the air groove 19 and the air holes 20 can generate negative pressure, so that the fertilizer packaging bag placed inside the lower hopper 3 is adsorbed on the inner wall of the lower hopper 3, thereby improving the sealing between the lower hopper 3 and the packaging bag, and further reducing the dispersion of dust.

[0040] The telescopic sheet 10 comprises a movable sheet 1001 and a telescopic rod 1002. The upper and lower ends of the movable sheet 1001 are provided with the telescopic rod 1002 of an arc structure.

[0041] A plurality of spirally distributed stirring rods 21 are provided on the rotating shaft of the auger 5. The stirring rods 21 break up large pieces of fertilizer when the auger 5 pushes the fertilizer to move.

[0042] Embodiment 2:

[0043] Embodiment 2 is based on Embodiment 1, and is different from Embodiment 1 in that the inner lower end surface of the cylinder 6 is a planar structure, and is provided with a scraper 22 of a scroll structure, the lower end surface of the scraper 22 is in contact with the inner lower end surface of the cylinder 6, and a driving device for driving the scraper 22 to rotate is provided at the bottom of the cylinder 6. The driving device drives the scraper 22 to rotate, and can scrape the fertilizer away from the center of the bottom of the cylinder 6 to the center, thereby facilitating the suction of the suction pipe 18.

[0044] Working principle: When in use, first, the worker opens one end of the fertilizer packaging bag, and then places the packaging bag with the opening facing downward in the lower hopper 3. Then the worker holds the handle 9, pulls the pull ring 16, drives the slide bar 14 to move, and further rotates the telescopic piece 10. The worker then places the telescopic piece 10 on the outside of the plant root, and then pushes the pull ring 16 in the opposite direction to reset the two telescopic pieces 10 to fit together to form a closed structure. Then the negative pressure device 7 and the driving member 4 are started in sequence. The negative pressure device 7 generates suction through the air pipe, the air groove 20 and the air hole 19, so that the packaging bag is adsorbed on the inner wall of the lower hopper 3. Since the opening of the packaging bag faces downward, the fertilizer in the bag falls along the lower hopper 3 into the feeding pipe 2. The driving member 4 drives the auger 5 to rotate and pushes the fertilizer into the cylinder 6. Subsequently, the fertilizer is discharged through the handle 9 along the connecting pipe 8 under the suction force generated by the suction pipe 18. The fertilizer falls in the telescopic piece 10 and then covers the soil at the roots of the plants.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
