[0027] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the attached drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects according to the present utility model as follows.

[0028] Please refer to Figures 1 - 5 As shown, the purpose of this embodiment is to provide a deep crushing mechanism for biological fertilizers, including a crushing box 2. A disc-shaped cutting tool 201 is provided inside the crushing box 2. Saw teeth 2013 are provided on the edge of the cutting tool 201. The saw teeth 2013 are fixedly connected to the cutting tool 201. Spines 2015 are provided on the outer surface of the saw teeth 2013. The spines 2015 are fixedly connected to the saw teeth 2013. The spines 2015 can increase the force of crushing biological fertilizers and make the crushing more thorough. Limiting pieces 202 are provided on both sides of the cutting tool 201. The limiting pieces 202 are threadedly connected to the roller shaft 203. The limiting pieces 202 can be screwed along the roller shaft 203 to limit the displacement of the cutting tool 201;

[0029] The cutting tool 201 is composed of an upper cutting tool piece 2011 and a lower cutting tool piece 2012. Teeth 2014 are provided on the contact surfaces of the upper cutting tool piece 2011 and the lower cutting tool piece 2012. The teeth 2014 are fixedly connected to the upper cutting tool piece 2011 and the lower cutting tool piece 2012. The teeth 2014 make the upper cutting tool piece 2011 and the lower cutting tool piece 2012 bite each other to prevent the upper cutting tool piece 2011 and the lower cutting tool piece 2012 from detaching from the roller shaft 203.

[0030] There are two roller shafts 203 arranged inside the crushing box 2. The roller shafts 203 are arranged in parallel on the same horizontal plane. The roller shafts 203 are movably connected to the cutter 201, and the roller shafts 203 are threadedly connected to the limiting pieces 202. The two roller shafts 203 roll in opposite directions to drive the cutter 201 to extrude and cut the biological fertilizer.

[0031] There is a crushing box inner cavity 205 arranged inside the crushing box 2. The crushing box inner cavity 205 accommodates the biological fertilizer to be crushed. There is a discharge port 204 provided at the front side of the bottom of the crushing box inner cavity 205. The discharge port 204 is communicated with the crushing box inner cavity 205, and the biological fertilizer in the crushing box inner cavity 205 slides out from the discharge port 204.

[0032] There is a feed box 1 provided at the upper part of the crushing box 2. The feed box 1 is detachably connected to the crushing box 2. When it is necessary to crush the biological fertilizer, the feed box 1 is placed on the upper part of the crushing box 2 to accommodate the biological fertilizer to be crushed. When it is not necessary to crush the biological fertilizer, the feed box 1 is removed from the crushing box 2, which is convenient for the handling of the biological fertilizer deep crushing mechanism and also convenient for replacing the damaged feed box 1.

[0033] There are support legs 102 respectively provided at the four corners of the bottom of the feed box 1. The tops of the support legs 102 are fixedly connected to the feed box 1. The four support legs 102 are respectively inserted into the four corners of the crushing box 2 to fix the feed box 1, and the feed box 1 is provided with a feed hopper 101. The biological fertilizer to be crushed is directly put into the feed hopper 101.

[0034] There are machine bases 3 provided on both sides of the crushing box 2. The machine bases 3 provide support force for the crushing box 2. The machine bases 3 are composed of a left support 302 and a right support 303. The right support 303 is fixedly connected to the crushing box 2, and the left support 302 is fixedly connected to the crushing box 2. The motor (not shown in the figure) inside the left support 302 can drive the roller shaft 203 to rotate.

[0035] There is a switch 301 provided in the middle of the upper part of the left side surface of the left support 302. The switch 301 is fixedly connected to the left support 302. The switch 301 is used to control the power on and off of the motor (not shown in the figure).

[0036] In the specific implementation of the present utility model, the feed box 1 is lifted above the mashing box 2, and the four legs 102 are respectively aligned with the four corners of the mashing box 2. Then the feed box 1 is lowered, and the four legs 102 are respectively inserted into the four corners of the mashing box 2 to fix the feed box 1. The biological fertilizer to be mashed is put into the feed hopper 101, and a clean container is placed below the discharge port 204 to receive the mashed biological fertilizer. Press the switch 301 to start the motor (not shown in the figure) in the machine base 3. The motor drives the roller shafts 203 to rotate in opposite directions, and the cutting tools 201 on the roller shafts 203 also rotate in opposite directions along with the roller shafts 203. At the same time, the biological fertilizer falling on the cutting tools 201 is squeezed and cut. If the biological fertilizer put into the feed hopper 101 is square or irregular in shape, the cutting tools 201 directly cut the biological fertilizer thereon. If the biological fertilizer put into the feed hopper 101 is cylindrical or spherical, the saw teeth 2013 on the cutting tools 201 first pierce into the biological fertilizer with the rolling of the roller shafts 203 to fix the biological fertilizer, and then cut it to prevent it from rolling along with the roller shafts 203 on the surface of the roller shafts 203 and being unable to be chopped by the cutting tools 201. The biological fertilizer in contact with the blades is squeezed between the cutting tools 201 with the rotation of the roller shafts, and the vertebral spines 2015 on the saw teeth 2013 pierce into the body of the biological fertilizer to deepen the degree of pulverization of the biological fertilizer. The cut biological fertilizer is transported to the inner cavity 205 of the mashing box with the rotation of the roller shafts 203 and finally slides out from the discharge port 204 and falls into the pre-placed container.

[0037] The cutters 201 on the roller shaft 203 are all independent of each other, and there is a limit piece 202 on each side of each cutter 201 to fix the cutter 201 without displacement. If a cutter 201 is damaged and affects the crushing quality of the biological fertilizer, the damaged cutter 201 needs to be replaced. Lift the feeding box 1 upward, pull out all four legs 102 of the feeding box 1 from the crushing box 2, remove the feeding box 1, expose the upper part of the crushing box 2, rotate the damaged cutter 201 so that the upper cutter piece 2011 and the lower cutter piece 2012 are respectively located on the front and rear sides of the roller shaft 203, which is convenient for removing the cutter 201. The operator screws the limit pieces 202 on both sides of the damaged cutter 201 from above to make the limit pieces 202 away from the cutter 201, losing the restrictive effect on the cutter 201. Hold the upper cutter piece 2011 and the lower cutter piece 2012 respectively and move them left and right to separate the upper cutter piece 2011 and the lower cutter piece 2012 from each other, then pull them in the direction away from the roller shaft 203, and finally lift them upward and take them out of the crushing box 2. Place the new upper cutter piece 2011 and the lower cutter piece 2012 vertically on both sides of the roller shaft 203 lacking the cutter 201, making the upper cutter piece 2011 and the lower cutter piece 2012 stagger left and right and the teeth 2014 correspond to each other. Push the upper cutter piece 2011 towards the lower cutter piece 2012 to make their teeth 2014 bite together. After the upper cutter piece 2011 and the lower cutter piece 2012 are neatly bitten, screw the limit pieces 202 on both sides of the cutter 201 until both limit pieces 202 tightly adhere to both sides of the cutter 201, firmly fixing the cutter 201 without displacement. Since the cutters 201 on the roller shaft 203 are all independent of each other, when a cutter 201 is damaged, only the damaged cutter 201 needs to be replaced, and it is not necessary to replace all the cutters 201 on the entire roller shaft 203, reducing the cost.

[0038] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
