[0002] In the process of making organic fertilizer, active ingredients need to be added, such as beneficial bacteria, functional bacterial agents, phosphate rock powder and potash rock powder, etc. The amount of these ingredients is generally small, and it is very easy to mix them unevenly when mixed directly. Therefore, a feeding device is needed to control the amount of active ingredient raw materials added. Such devices include hoppers, conveying devices, metering devices, mixers and control systems. The hopper is used to store active ingredients, the conveying device is responsible for transporting the active ingredients from the hopper to the mixer, the metering device controls the amount of active ingredients added, the mixer mixes the active ingredients with the organic fertilizer raw materials, and the control system is responsible for controlling the operation of the entire feeding device. These parts work together to ensure that the active ingredients are added evenly and accurately, and to improve the quality and effect of the organic fertilizer. However, the current feeding device is generally weighed first during use, and the weighed active ingredient raw materials are then fed by a conveying device, such as a screw conveyor or a belt feeder, until they are fed into the organic fertilizer processing device. Since the weighing and conveying processes need to be performed separately and cannot be performed at the same time, the equipment utilization rate is low during the entire feeding process, and the material handling and transfer during the weighing and conveying processes will also waste a certain amount of time, thereby affecting the efficiency of the entire organic fertilizer production process.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-5The utility model provides an embodiment: a low-dose material precision feeding device for organic fertilizer production, comprising a base frame 1 and a conveying frame 2 fixed at the top of the base frame 1, and a belt conveying mechanism 3 for conveying raw materials is installed inside the conveying frame 2, a bracket 6 is installed on one side of the top of the conveying frame 2, and a mixing box 7 and a storage box 8 are installed on the top of the bracket 6, a staking tube 10 is installed at the center position of the bottom of the mixing box 7, and an electric material control valve 11 is installed at the bottom of the staking tube 10, a weighing module 13 for detecting the weight of raw materials on the belt conveying mechanism 3 is installed inside the side of the conveying frame 2 close to the bracket 6, a PLC control panel 5 is installed on one side of the surface of the conveying frame 2, the output end of the PLC control panel 5 is electrically connected to the belt conveying mechanism 3 and the input end of the electric material control valve 11, and the PLC control panel 5 and the weighing module 13 are bidirectionally electrically connected;

[0019] The belt conveying mechanism 3 includes a main support roller 302, an auxiliary support roller 301, and a transmission belt 304 sleeved on the outer sides of the auxiliary support roller 301 and the main support roller 302, which are rotatably installed at both ends of the conveying frame 2. The belt conveying mechanism 3 also includes a plurality of belt support rollers 303 rotatably installed inside the conveying frame 2 at equal intervals, and a stepper motor 4 installed on one side of the surface of the conveying frame 2. The output end of the stepper motor 4 is fixedly connected to one end of the main support roller 302 through a coupling. During the operation of the belt conveying mechanism 3, the rotary power of the stepper motor 4 is transmitted to the main support roller 302, and the transmission belt 304 is driven to rotate. In this process, the belt support roller 303 supports the transmission belt 304. The belt support roller 303 is no longer installed at the portion of the transmission belt 304 close to the side of the bracket 6, so that the transmission belt 304 can press the weighing module 13 under the action of the material to ensure that the weighing module 13 detects the weight of the material;

[0020] The weighing module 13 includes two symmetrical trusses 1301 fixed inside the conveying frame 2, a right-angle platform 1302 installed on the top wall of the trusses 1301, and a weighing sensor 1305 installed on the bottom of the right-angle platform 1302. A flat plate 1304 is installed on the detection end of the weighing sensor 1305, and the upper surface of the flat plate 1304 is in contact with the top wall of the transmission belt 304.

[0021] Z-shaped reeds 1303 are installed on both sides of the bottom of the flat plate 1304. The bottom of the Z-shaped reed 1303 is fixedly connected to the bottom wall of the right-angle platform 1302. During the operation of the weighing module 13, the transmission belt 304 exerts pressure on the flat plate 1304 under the action of the gravity of the material. At this time, the Z-shaped reed 1303 is in a compressed state, and the flat plate 1304 exerts pressure on the weighing sensor 1305, thereby detecting the weight of the material on the surface of the transmission belt 304, realizing accurate detection and control of the material conveying amount and the feeding amount, and improving the feeding accuracy of the device;

[0022] A mixing structure 9 is provided inside the mixing box 7, and a pulley transmission structure 12 for maintaining power connection with the mixing structure 9 is installed at one end of the main support roller 302 away from the stepper motor 4. The mixing structure 9 includes a U-shaped frame 901 fixed on the front and rear inner walls of the mixing box 7, a bearing seat 902 fixed at the top of the U-shaped frame 901, and a mixing shaft 903 installed between the two bearing seats 902. The same end of the mixing shaft 903 and the main support roller 302 is connected to power through the pulley transmission structure 12;

[0023] When the stepper motor 4 is driving the belt conveyor mechanism 3 to work, a part of the rotational power of the stepper motor 4 is transmitted to the mixing structure 9 through the pulley transmission structure 12, that is, the mixing shaft 903 is driven to rotate, and the mixing shaft 903 is used to mix the raw materials inside the mixing box 7. By continuously stirring the raw materials, the active ingredients can be kept in a dispersed state to avoid agglomeration and agglomeration, thereby ensuring the fluidity of the raw materials and ensuring that the powdered raw materials can be discharged to the belt conveyor mechanism 3 through the pulley transmission structure 12.

[0024] When the embodiment of the present application is in use, the staff first puts a sufficient amount of active ingredients, i.e., beneficial bacteria, functional bacterial agents, phosphate rock powder or potassium rock powder, etc., into the storage box 8 and the mixing structure 9. When the active ingredients are added, the operator sets the amount of active ingredients to be added on the PLC control panel 5, and turns on the stepper motor 4 to work. The PLC control panel 5 sends instructions to the electric material control valve 11 and the weighing module 13. During this process, the belt conveyor mechanism 3 works under the drive of the stepper motor 4 and continuously conveys the active ingredient raw materials. During the conveying process, the weighing module 13 detects the weight of the raw materials in real time and transmits the weighing data to the PLC control panel 5. When it is detected that the weight of the raw materials reaches the set parameters, the PLC control panel 5 sends a closing signal to the electric material control valve 11. After receiving the closing signal from the PLC control panel 5, The electric material control valve 11 is immediately closed to prevent the active ingredient raw materials in the mixing box 7 and the storage box 8 from continuing to be discharged onto the belt conveyor mechanism 3. When the belt conveyor mechanism 3 transports the existing active ingredient raw materials to the organic fertilizer mixer, the addition process is completed. The PLC control panel 5 records the amount added this time and prepares for the next addition. According to production requirements, the operator can set a new addition amount through the PLC control panel 5, and then repeat the above process to achieve the cyclic addition of active ingredients. During the operation of the device, the weighing module 13 is combined with the belt conveyor mechanism 3 to achieve simultaneous material transportation and weighing, thereby reducing the time for material handling and transfer and improving the efficiency of the entire feeding process. In addition, since material transportation and weighing are carried out simultaneously, the retention time of materials in the transportation process can be reduced, thereby improving the transportation and feeding efficiency.
