These terms are only used to distinguish the same type of information from each other. In addition, the terms "vertical", "horizontal", "upper", "lower" and similar expressions used in the present application are positional relationships with reference to the accompanying drawings, and do not represent the expression of the only embodiment.

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] In a first aspect, an embodiment of the present application discloses a humic acid fertilizer reaction device 1 .

[0034] Reference Figure 1A humic acid fertilizer reaction device 1 includes a frame 11 and a reaction box 12 fixed on the frame 11. The reaction box 12 includes a base 121 and a protective cover 122, and the protective cover 122 is fixed on the upper side of the base 121. The base 121 is fixedly connected to the frame 11 by bolts. A feeding port 1221 is provided at the top of the protective cover 122, and the feeding port 1221 is used to feed raw materials such as kitchen waste, dead branches and leaves. It should be understood that the raw materials may also include other organic wastes. A discharge port 1222 is provided on one side wall of the protective cover 122 for discharging fermented materials, and a sealing plate 1223 for opening and closing the discharge port 1222 is movably provided on the protective cover 122.

[0035] Reference Figure 1 and Figure 2 A conversion agent supply mechanism 13 is provided on one side of the reaction box 12. In this embodiment, as a preferred implementation, the conversion agent supply mechanism 13 is provided on the side of the reaction box 12 away from the discharge port 1222. Thus, it is not easy to affect the discharge, and the space around the reaction box 12 is fully utilized.

[0036] Reference Figure 2 The conversion agent supply mechanism 13 includes a storage tube 131, a piston rod 132 and a compensation box 133, and the storage tube 131 and the compensation box 133 are used to hold the conversion agent. The conversion agent includes at least one of Bacillus subtilis, Aspergillus oryzae, Bacillus licheniformis, Thermospora thermophila and Bacillus pumilus. Bacillus subtilis, Aspergillus oryzae, Bacillus licheniformis, Thermospora thermophila and Bacillus pumilus can all decompose cellulose and effectively improve the soil. Among them, Thermospora thermophila has strong survival ability and can survive in high temperature, drought or humid environment, and has extremely strong decomposition ability. Under the synergistic effect with other microorganisms, it can quickly decompose organisms in the soil into easily absorbable small molecular nutrients for the growth of crops. Bacillus pumilus is used to reduce the occurrence of crop diseases and insect pests.

[0037] Reference Figure 2 The storage tube 131 is arranged horizontally and is fixedly connected to the reaction box 12. Part of the storage tube 131 is located outside the reaction box 12, and one end of the storage tube 131 penetrates into the reaction box 12. The piston rod 132 is slidably arranged at the end of the storage tube 131 that passes through the reaction box 12.

[0038] Reference Figure 2The compensation box 133 is fixedly mounted on the frame 11. The compensation box 133 is located above the storage tube 131. A liquid infusion tube 134 is connected between the bottom of the compensation box 133 and the storage tube 131. A support rod 135 is connected between the bottom of the compensation box 133 and the frame 11, so as to fix the compensation box 133 at a higher height. A first one-way valve (not shown) is provided at the end of the storage tube 131 that penetrates into the reaction box 12. The first one-way valve is used to unidirectionally guide the flow path of the conversion agent in the storage tube 131 to the reaction box 12. A second one-way valve (not shown) is provided in the liquid infusion tube 134. The second one-way valve is used to unidirectionally guide the flow direction of the conversion agent from the compensation box 133 to the storage tube 131. In the length direction of the storage tube 131, the second one-way valve is located between the piston rod 132 and the first one-way valve.

[0039] Reference Figure 2 , the direction in which the piston rod 132 moves toward the reaction box 12 is defined as the first direction, and the direction in which the piston rod 132 moves away from the reaction box 12 is defined as the second direction, that is, the first direction is opposite to the second direction. Therefore, when the piston rod 132 moves along the first direction, the conversion agent can be poured into the reaction box 12 to overcome the resistance of the first one-way valve. When the piston rod 132 is not subjected to the driving force along the first direction, the conversion agent in the replenishment tank overcomes the resistance of the second one-way valve by gravity and flows into the storage tube 131, so that the conversion agent stock in the storage tube 131 is replenished, thereby pushing the piston rod 132 to move and reset along the second direction.

[0040] Reference Figure 3 , Figure 4 and Figure 5 , a lifting platform 123 and an elastic member 124 are provided in the reaction box 12. The lifting platform 123 is slidably arranged in the reaction box 12 along the vertical direction. A lifting column 1231 is fixed to the bottom of the lifting platform 123. The lifting column 1231 is located at the center of the lifting platform 123. The lifting column 1231 is connected to the base 121 along the vertical direction. The elastic member 124 is a compression spring, and the elastic member 124 is sleeved on the lifting column 1231. An installation chamber 125 is provided between the lifting platform 123 and the base 121. The elastic member 124 is arranged in the installation chamber 125. The elastic member 124 is used to apply an upward elastic force to the lifting platform 123.

[0041] Reference Figure 4 and Figure 5 A transmission mechanism 14 is also provided in the installation chamber 125, and the transmission mechanism 14 is connected between the piston rod 132 and the lifting platform 123. Two groups of transmission mechanisms 14 are provided, and the two groups of transmission components are symmetrically arranged about the center of the reaction box 12. Both groups of transmission mechanisms 14 are connected between the lifting platform 123 and the piston rod 132 to improve the driving force of the piston rod 132 and the structural symmetry of the overall reaction device.

[0042] Reference Figure 4 and Figure 5 The transmission mechanism 14 includes a first transmission assembly 141, a one-way transmission assembly 142 and a second transmission assembly 143, which are sequentially connected in transmission. The first transmission assembly 141 is connected to the lifting platform 123, and the second transmission assembly 143 is connected to the piston rod 132. The one-way transmission assembly 142 is used to realize the transmission connection between the first transmission assembly 141 and the second transmission assembly 143 when the lifting platform 123 descends; the second transmission assembly 143 is used to intermittently drive the piston rod 132 to slide along the first direction.

[0043] Reference Figure 5 and Figure 6 The first transmission assembly 141 includes a first gear 1411 and a first rack 1412. The first gear 1411 is rotatably connected to the installation chamber 125. The first rack 1412 is meshed with the first gear 1411. The first rack 1412 is vertically arranged. The first rack 1412 is fixedly connected to the lifting platform 123. The first gear 1411 is connected to the one-way transmission assembly 142. A first guide seat 1413 is fixed on the base 121. The first rack 1412 is vertically slidably connected to the first guide seat 1413.

[0044] Reference Figure 5 and Figure 6 The one-way transmission assembly 142 includes a ratchet 1421, a driven disk 1422 and a ratchet 1423. The ratchet 1423 is rotationally connected to the driven disk 1422 through a torsion spring. The ratchet 1423 rotates toward the ratchet 1421 under the drive of the torsion spring. The ratchet 1421 is coaxially transmission-connected with the first gear 1411, and the driven disk 1422 is transmission-connected with the second transmission assembly 143. The ratchet 1421 and the ratchet 1423 are one-way transmission, that is, when the lifting platform 123 descends, the ratchet 1421 can mesh with the ratchet 1423 and drive the driven disk 1422 to rotate. When the lifting platform 123 rises, the ratchet 1421 cannot drive the ratchet 1423 to rotate.

[0045] Reference Figure 5 and Figure 6The second transmission assembly 143 includes a second gear 1431 and a second rack 1432. The second gear 1431 is rotatably connected to the reaction box 12. The second rack 1432 is slidably connected to the reaction box 12 along the horizontal direction. The second gear 1431 is meshed with the second rack 1432. The second gear 1431 is transmission-connected to the driven disk 1422. The second rack 1432 is connected to the piston rod 132. The sliding direction of the second rack 1432 is parallel to the sliding direction of the piston rod 132. A second guide seat 1433 is fixed on the base 121. The second rack 1432 is slidably connected to the second guide seat 1433. The second guide seat 1433 is parallel to the length direction of the storage tube 131.

[0046] Reference Figure 5 and Figure 6 In order to prevent the piston rod 132 from being separated from the storage tube 131, a limit block 126 is fixed on the base 121, and the limit block 126 is used to limit the moving distance of the second rack 1432 along the second direction. Specifically, the piston rod 132 is connected to a moving frame 136, and a connecting rod 137 is connected between the second racks 1432 in the two sets of transmission mechanisms 14 and the moving frame 136. The limit block 126 is used to limit the moving distance of the connecting rod 137 along the second direction. A slide rail 138 is also fixed on the base 121, and the moving frame 136 is connected to the slide rail 138. The moving frame 136 is slidably connected to the base 121 through the slide rail 138.

[0047] Reference Figure 5 and Figure 6 It should be understood that, when it is necessary to limit the moving distance of the piston rod 132 along the second direction, a limiter can be set to limit the moving distance of the movable frame 136 or directly limit the moving distance of the piston rod 132, and the present application does not impose any restrictions on this.

[0048] Reference Figure 5 and Figure 6 When the diameter of the storage tube 131 is small, the movement of the piston rod 132 needs to be increased to ensure the amount of conversion agent added. Since the space of the installation chamber 125 is limited, the descending height of the lifting platform 123 is limited, so a speed increasing gear set 144 is connected between the one-way transmission assembly 142 and the second transmission assembly 143.

[0049] Reference Figure 5 and Figure 6The speed increasing gear set 144 includes a driving gear 1441 and a driven gear 1442, both of which are rotatably connected to the installation chamber 125 of the reaction box 12, the driving gear 1441 is meshed with the driven gear 1442, the diameter of the driven gear 1442 is smaller than the diameter of the driving gear 1441, the driving gear 1441 is coaxially connected to the driven disk 1422, and the driven gear 1442 is coaxially connected to the second gear 1431. The diameter of the driven gear 1442 is smaller than the diameter of the second gear 1431.

[0050] Therefore, even if the descending height of the lifting platform 123 is very small, the rotation speed of the second gear 1431 can be increased under the transmission of the speed-increasing gear set 144, thereby increasing the sliding distance of the piston rod 132.

[0051] The implementation principle of the humic acid fertilizer reaction device 1 of the embodiment of the present application is: the crushed and stirred raw materials are put into the reaction box 12 from the feeding port 1221, so that the raw materials fall on the lifting platform 123. As the amount of raw materials put in gradually increases, the lifting platform 123 descends. The lifting platform 123 drives the first rack 1412 to descend, the first rack 1412 drives the first gear 1411 to rotate, the first gear 1411 drives the ratchet 1421 to rotate, the ratchet 1421 drives the driven disk 1422 to rotate through the ratchet pawl, the driven disk 1422 drives the driving gear 1441 to rotate, the driving gear 1441 drives the driven gear 1442 to rotate, the driven gear 1442 drives the second gear 1431 to rotate, the second gear 1431 drives the second rack 1432 to rotate in the first direction, the second rack 1432 drives the piston rod 132 to move in the first direction through the connecting rod 137 and the movable frame 136, thereby overcoming the resistance of the first one-way valve on the storage tube 131 and putting the conversion agent into the reaction box 12.

[0052] Since the descending height of the lifting platform 123 is linearly related to the sliding distance of the piston rod 132, the input amount of raw materials and the added amount of the conversion agent are in a certain ratio, thereby being able to improve the accuracy of the ratio of raw materials such as kitchen waste and the conversion agent. The quality and production efficiency of biological humic acid fermentation are improved. In addition, the present application uses a mechanical structure for transmission. Compared with the use of various sensors to sense the input amount of raw materials and conversion agents, since the sensor relies on electrical signal transmission for sensing and is prone to distortion, the overall mechanical structure of the present application is not easy to be damaged and can achieve accurate ratios.

[0053] After the fermentation of the raw materials and the conversion agent in the reaction box 12 is completed, the discharge port 1222 is opened to discharge the materials for the next process to obtain humic acid fertilizer. After the materials are discharged, the lifting platform 123 moves upward and resets under the drive of the elastic member 124, so that the ratchet 1421 cannot drive the driven disk 1422 to rotate, that is, the transmission mechanism 14 has no driving force on the piston rod 132. At this time, the conversion agent in the compensation box 133 relies on gravity to overcome the resistance of the second one-way valve in the liquid replenishment tube 134 and flows into the storage tube 131, thereby driving the piston rod 132 to move and reset along the second direction.

[0054] In a second aspect, an embodiment of the present application provides a device for preparing humic acid fertilizer.

[0055] Reference Figure 7 A humic acid fertilizer preparation device includes a crushing device 2, a stirring device 3 and the above-mentioned humic acid fertilizer reaction device 1. The crushing device 2 and the stirring device 3 can use conventional crushing equipment and stirring equipment to crush and stir raw materials such as kitchen waste, dead branches and leaves, and finally put them into the reaction box 12.

[0056] The humic acid fertilizer preparation device can improve the production efficiency of biological humic acid through the crushing device 2, the stirring device 3 and the humic acid fertilizer reaction device 1.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
