The maximum diameter of the blade head is 10CM, and there is a blade every 4CM. The thickness of the blade is 0.1 cm.

[0056] The volume of the crushing area = (0.26 + 0.10) * 0.16 * 0.24 / 2 = 0.006912 cubic meters, that is, a maximum of 6 liters of household kitchen waste can be crushed at one time. The feed hopper 4 is installed on the top of the box body 1 through a double slide. The integrated box door 2 is opened, and the feed hopper 4 can be pulled out of the box body 1 for easy cleaning.

[0057] The green concept of no electricity is an important improvement of the utility model. At the front of the crushing blade 5, the driving box 53 is connected through the rotating rod 51. When the pull rope 539 at the top is pulled, the pull rope 539 drives the rotating rod 51 to rotate, and the rotating rod 51 drives the blade 511 to rotate quickly. By pulling the pull rope multiple times, the leaves and peels can be cut into pieces to complete the crushing function. There is a protrusion of 28CM long * 2CM wide * 16CM high on the upper part of the box door 2 corresponding to the crushing area. When the box door 2 is closed, the position of the driving box 53 and the crushing blade 5 can be firmly fixed.

[0058] By rotating the handle 63 in both directions, the four shutter doors 61 of the feed opening 41 with a length of 10 cm and a width of 6 cm can be rotated 90 degrees in two directions, so that the feed opening 41 can be opened and closed freely.

[0059] The composting box is directly below the crushing box, and the composting area is composed of two drawer-type composting baskets 7 and two drawer-type fertilizer liquid trays 8. The box 1 and the composting basket 7 are connected and fixed by double middle slide rails 13 on both sides, and the two drawer-type composting baskets 7 can be exchanged at will, and the two drawer-type fertilizer liquid trays 8 can also be changed at will.

[0060] The dimensions of the drawer-type compost basket 7 are: length 26CM*width 27CM*height 18CM, thickness 1CM, and there are 156 (12*13) round holes as filter holes 71 at the bottom of the box body, and double-layer slideways are arranged on both sides.

[0061] Drawer-type compost basket 7 capacity = 0.24*0.25*0.17 = 0.0108 cubic meters, can store 10 liters of solid fertilizer.

[0062] The dimensions of the drawer-type fertilizer liquid tray 8 are: length 26CM*width 27CM*height 2.5CM, thickness 0.5CM. The front panel is equipped with a visual window and single-layer slides on both sides.

[0063] The capacity of the drawer-type fertilizer liquid tray 8 = 0.25*0.26*0.02 = 0.00130 cubic meters can store 1.3 liters of liquid fertilizer.

[0064] For example, a family of three produces about one pound of pre-meal kitchen waste such as vegetable leaves and fruit peels every day. A 10L compost basket 7 can basically meet the pre-meal kitchen waste accumulation for two weeks. After the crushed kitchen waste is added with EM bacteria, the initial fermentation can be basically completed within two weeks and most of the liquid fertilizer can be produced. Two 10L compost baskets 7 can basically meet the composting needs of an average family for one month and can be recycled.

[0065] Before use, the utility model first checks whether the rotating handle 63 of the feed port 41 is in the initial state, that is, the door body 61 is in the closed state, and then closes the box door 2. Press the spring button on the top of the box body 1, the hatch 3 of the feed port 11 opens automatically, and the pre-meal kitchen waste is put into the integrated machine crushing area. The box door 2 and the hatch 3 must be closed before pulling the pull rope 539 on the top of the box body 1. Pull the pull rope 539 back and forth to observe whether the raw materials are crushed through the transparent hatch 3 on the top. After the crushing is completed, open the box door 2, turn the rotating handle 63 to open the shutter door 61 of the feed port 41, let the raw materials enter the composting area, add an appropriate amount of EM bacteria, and stir and compact the raw materials with a shovel. The operation can be repeated each time until the upper compost basket 7 is full, and then it is exchanged with the empty compost basket 7 on the lower layer. The solid fertilizer in the compost basket 7 can be taken out after two to four weeks of accumulation and buried in the planting soil to continue to decompose. The accumulated liquid in the fertilizer liquid tray 8 can be observed through the visual window on the box door 2, and it can be emptied in time to avoid overflow of the accumulated liquid. In addition to fertilizing plants, liquid fertilizer can also be used as a cleaning agent to remove oil stains, and can also be poured into sewers to dredge pipes. There is activated carbon inside the door 2 to absorb odors. Keep the door 2 closed on weekdays to ensure anaerobic fermentation. The composting machine has a unique slide-type fixed design, and each component can be pulled out of the box for thorough cleaning. It makes daily composting easy and convenient for families.
