[0002] Straw fermentation is a method for improving the nutritional value of crop straw, also known as straw microbial fermentation storage technology. Before the fermentation treatment of straw, it is usually necessary to pretreat the straw, such as crushing work, which can be crushed into small particles or fragments. This treatment method helps to speed up the decomposition rate of the straw, because the surface area of the straw will become larger due to crushing, and microorganisms are more likely to decompose organic matter in the case of larger surface area. After crushing, the straw is easier to mix with other organic materials to form a better organic fertilizer pile. For enterprises that need to use straw or straw products for production, crushing straw can not only improve production efficiency, but also make it more convenient when processing.

[0003] In the prior art, after the straw material enters the pretreatment device for pretreatment and crushing, it is usually necessary to use a screen to preliminarily separate the crushed straw material, and the straw material that has not been crushed to the required size is put into the pretreatment device again for secondary crushing to ensure the crushing effect of the pretreatment device. However, during the lifting process, the single mechanical lifting mechanism (such as an auger) is not ideal for lifting and conveying the unevenly sized and light-weight straw material after preliminary crushing, as the small particles or sheet-shaped straw material can easily get stuck between the lifting mechanism and the wall, causing wear or falling, resulting in unsatisfactory lifting effect.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so as to implement the embodiments of the utility model described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0023] As Figures 2-5 ​​The utility model discloses a straw pulverizer with air dynamic energy auxiliary material lifting, including the body 1, its characterized in that, the body 1 is set up with the feeding cavity 2, the sliding flow cavity 3, the lifting cavity 4 and the overflow slot 5 in it, the lifting cavity 4 is set up in the inclined vertical type, the bottom of feeding cavity 2 is communicated with the bottom of lifting cavity 4 through the sliding flow cavity 3, the sliding flow cavity 3 is arranged in the inclined type, and its lower end is located at one side of lifting cavity 4, the upper portion of lifting cavity 4 is communicated with feeding cavity 2 through overflow slot 5, and overflow slot 5 is arranged in the inclined type, and its lower end is located at one side of feeding cavity 2,

[0024] The bottom of feeding cavity 2 is provided with a pulverizing cutter head 201, the bottom wall of sliding flow cavity 3 is provided with a discharge port, and a screen 301 is arranged at the discharge port, the lifting cavity 4 is rotatably connected with a screw conveyor 401 penetrating the length direction of the lifting cavity 4, and the lifting cavity 4 is provided with an air driving mechanism for separating the straw material from the screw conveyor 401 or the inner wall of the lifting cavity 4.

[0025] The use principle of the utility model is as follows: the straw enters the body 1 through the feeding cavity 2, and the straw is pulverized by the pulverizing cutter head 201 when the straw reaches the bottom of the feeding cavity 2. With the straw continuously entering the feeding cavity 2, the broken straw material is pushed into the sliding flow cavity 3, and the straw particles meeting the screening size of the screen 301 are discharged from the discharge port through the screen 301. The straw material not passing through the screen 301 enters the lifting cavity 4 along the downwardly inclined sliding flow cavity 3 and is lifted by the screw conveyor 401, so that the preliminarily pulverized straw material moves upward, and when reaching the overflow slot 5, the straw material enters the feeding cavity 2 again for pulverizing processing due to the action of gravity. By arranging the air driving mechanism in the lifting cavity 4, air flow is generated during the lifting work of the screw conveyor 401 to prevent the straw material with small particles or in the form of a sheet from being stuck between the lifting mechanism and the pipe wall, and the air flow of the air flow is used to assist the screw conveyor 401 in lifting the straw material with uneven particle size and light weight after pulverizing, so that the conveying and lifting effect of the lifting mechanism on the material can be improved.

[0026] The air driving mechanism includes a first fan 601 fixedly installed at the top end of the lifting cavity 4, and the first fan 601 has a blowing mode towards the inside of the lifting cavity 4 and a suction mode towards the outside of the lifting cavity 4.

[0027] When the first fan 601 blows air into the lifting cavity 4, the straw debris adhering to the inner wall of the lifting cavity 4 can be effectively blown away, and when the first fan 601 sucks air out of the lifting cavity 4, upward air flow is generated in the lifting cavity 4 to assist the upward lifting of the straw material.

[0028] The air driving mechanism includes a second fan 602 fixedly installed at the side edge of the bottom of the lifting cavity 4, and the second fan 602 has a blowing mode towards the screw conveyor 401.

[0029] The second fan 602 can effectively blow off the straw debris adhering between the auger 401 screw shaft and screw blade, reducing mechanical wear. At the same time, the second fan 602 can generate upward airflow to assist the upward lifting of the straw material, improving the lifting efficiency.

[0030] As a more preferred embodiment, the air driving mechanism includes a first fan 601 fixedly installed at the top end of the lifting chamber 4 and a second fan 602 fixedly installed at the bottom side of the lifting chamber 4. The first fan 601 has a blowing mode towards the inside of the lifting chamber 4 and a suction mode towards the outside of the lifting chamber 4. The second fan 602 has a blowing mode towards the auger 401.

[0031] As shown in Figure 1 As an embodiment, the machine body 1 is surface-mounted with a control unit 603 for controlling the working state of the air driving mechanism. The control unit 603 can control the airflow direction and intensity in the lifting chamber 4, and can be switched according to actual needs.

[0032] The first fan 601 and the second fan 602 can be simultaneously selected in blowing mode and airflow intensity, improving the flow speed of the airflow, and avoiding the accumulation of straw debris between the auger 401 screw shaft and screw blade, and between the lifting chamber 4 and the auger 401.

[0033] In order to achieve auxiliary lifting, the suction mode of the first fan 601 and the blowing mode of the second fan 602 can be used simultaneously, which can promote the straw material to be lifted to the upper part of the lifting chamber 4 faster to a certain extent.

[0034] The suction mode of the first fan 601 and the blowing mode of the second fan 602 can also be alternately selected and used. For example, after the suction mode of the first fan 601 is operated for a period of time, it is switched to the working state of the second fan 602, so as to avoid the continuous operation of the first fan 601 causing the smaller and lighter straw material to adhere to the air inlet end of the first fan 601, causing blockage, and ensuring the stability of the airflow in the lifting chamber 4.

[0035] Every time after being used for a period of time, the first fan 602 can be switched to blowing state to disperse the straw debris adhering to the inner wall of the lifting chamber 4.

[0036] More preferably, the bottom wall of the feeding chamber 2, the bottom wall of the lifting chamber 4 and the inclination of the screen 301 are the same, and they are in the same plane, so that the straw material entering the feeding chamber 2 can smoothly slide into the sliding chamber 3 and the lifting chamber 4 by gravity.

[0037] As an implementation manner, the pulverizing motor 202 for driving the pulverizing cutter 201 to rotate is embedded below the feeding cavity 2 in the machine body 1, and the transmission output end of the pulverizing motor 202 is fixedly connected with the pulverizing cutter 201. The lifting motor 402 for driving the auger 401 to rotate is embedded below the lifting cavity 4 in the machine body 1, and the transmission output end of the lifting motor 402 is fixedly connected with the auger 401.

[0038] The above is only the preferred embodiment of the present application, and does not limit the implementation range of the present application. It should be noted that, for ordinary technicians in the technical field, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should be covered within the protection scope of the present application.
