DETAILED DESCRIPTION

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] This embodiment discloses a specific structure of an organic fertilizer mixing device with quantitative feeding in a clumping manner, which is composed of a frame, a stirring device, a feeding device and a controller.

[0021] See also Figure 1 , Figure 2 As shown, the frame is a gantry structure, the lower end of which is a base 1, on which two vertically upwardly extending columns 2 are fixed, and the upper ends of the two columns 2 support and fix a crossbeam 5, on which a main shaft sleeve 14 is fixed.

[0022] See also Figure 1-Figure 5 As shown, the feeding device includes a main shaft 6, a second motor 7, a loading tray 9 and a plurality of third motors 4; the main shaft 6 extends in the vertical direction and is rotatably fixed in a main shaft sleeve 14 on the crossbeam 5. The main shaft 6 can rotate and can withstand the load brought by the feeding device. The upper end of the main shaft 6 is located above the crossbeam 5; the second motor 7 is fixed on the upper side of the crossbeam 5, and is connected to the upper end of the main shaft 6 by transmission, so as to drive the main shaft 6 to rotate; the main body contour of the loading tray 9 is disc-shaped, and the loading tray 9 and the main shaft 6 are connected. The lower ends of the loading tray 9 are connected and the central axes of the two coincide. The loading tray 9 is supported only by the main shaft 6, so that the loading tray 9 rotates synchronously with the main shaft 6, and the loading tray 9 always remains in a horizontal state during the rotation; a plurality of bins 8 are provided in the loading tray 9 for containing a variety of materials to be mixed, and these bins 8 are distributed around the central axis of the loading tray 9 to ensure that the load distribution of the loading tray 9 is balanced; a long strip-shaped feeding port 15 is opened at the lower end of each bin 8, and the feeding port 15 is along the diameter of the loading tray 9. At the same time, a rotatable material-dispensing shaft 18 is fixed in each silo 8, and the material-dispensing shaft 18 is located on the upper side of the corresponding feeding port 15 and the two extend in the same direction; a material-dispensing component 17 is fixed on the material-dispensing shaft 18, and the function of the material-dispensing component 17 is to drive the material in the silo 8 to be discharged from the feeding port 15, and the material in the silo 8 can be discharged from the feeding port 15 only when the material-dispensing shaft 18 rotates. Therefore, based on the setting intention of the material-dispensing component 17, it can be a toothed, The wing-shaped or columnar raised structures may also adopt other commonly used structural designs with material-discharging functions in the prior art; one end of the material-discharging shaft 18 extends to the outside of the silo 8 and is separately connected to a third motor 4, that is, each material-discharging shaft 18 is separately driven by a corresponding third motor 4; preferably, the third motor 4 is fixed to the outside of the loading tray 9 in a vertical installation manner, and the third motor 4 and the material-discharging shaft 18 are connected by a bevel gear 16, thereby improving the compactness of the feeding device.

[0023] See also Figure 1 , Figure 2 , Figure 5 As shown, the stirring device is supported by a frame, which consists of a stirring bin 10, a stirring mechanism 11 and a first motor 13, and is a vertical stirring machine; the upper end of the stirring bin 10 is a feed port, and the feed port is located directly below the loading tray 9, so that it can receive the material fed from the feeding port 15; the stirring mechanism 11 is rotatably fixed in the stirring bin 10, and the stirring mechanism 11 is driven by the first motor 13, and can stir and mix the materials in the stirring bin 10, and a discharge port 12 is provided at the lower part of the stirring bin 10.

[0024] See also Figure 1 , Figure 2As shown, the controller 3 can regulate the start and stop, speed and other operating states of the first motor 13, the second motor 7 and the third motor 4, and thus can control the working states of the feeding device and the stirring device.

[0025] The working principle and technical advantages of this organic fertilizer mixing device are:

[0026] 1. Quantitative delivery function.

[0027] When mixing materials, the various materials to be mixed are placed in different silos respectively. When the material-dispensing shaft drives the material-dispensing component to rotate, the materials in the silo are driven to be fed into the stirring device through the feeding port. Based on the above feeding method, the feeding rate and quantity can be controlled by adjusting the rotation speed and duration of the material-dispensing shaft. Therefore, according to the material mixing ratio requirements, the controller enables each third motor to work in a corresponding operating state, so as to realize the quantitative feeding of materials, so that various materials can be fed into the stirring device in proportion, without the need for manual measurement of the weight or volume of various materials, thus saving labor costs and improving production efficiency.

[0028] 2. Group breaking function.

[0029] When the feeding device is feeding, the high-speed rotating material-dispensing component can break up the clumped materials, achieve the purpose of breaking up the clumps, make the material particle size more uniform, facilitate the subsequent mixing operation, and improve the uniformity of the materials after mixing.

[0030] 3. Premixing function.

[0031] like Figure 5 As shown, under the control of the controller, the feeding device can feed various materials into the stirring device at a uniform speed according to the proportion requirements at the same time; during the feeding process, the controller drives the second motor 7 to drive the loading plate 9 to rotate, and various materials are discharged through the elongated feeding port 15 and then fall into the stirring bin 10 of the stirring device in a uniform and dispersed manner, thereby achieving premixing of the materials and greatly reducing the workload of the subsequent stirring device; the feeding device and the stirring device can perform two mixing operations on the materials in different action modes, thereby significantly improving the mixing efficiency and mixing effect of the organic fertilizer mixing device.

[0032] 4. Continuous processing function.

[0033] Since the feeding device can feed various materials into the stirring device at a uniform speed according to the mixing ratio, and break up and premix the materials during the feeding process, the materials entering the stirring bin already have a preliminary uniformity, and the materials are sufficiently mixed in the process of moving from top to bottom in the stirring bin. Therefore, the stirring device can continuously input and output, realize continuous processing of material mixing, and improve production efficiency.

[0034] In the organic fertilizer mixing device, since the feeding device can break the mass and premix the materials to be mixed, the workload of the stirring device is greatly reduced. Therefore, the present invention has no special technical requirements for the working performance of the stirring device. The stirring mechanism in the stirring device can adopt a conventional structure. For example, Figure 1 , Figure 2 The structure shown in the figure, that is, the stirring mechanism is composed of a stirring shaft and a stirring blade or a stirring frame fixed on the stirring shaft.

[0035] In the actual production of organic fertilizers, different requirements are placed on the accuracy of the raw material mixing ratio, or the amount of some specific materials needs to be precisely controlled, depending on the production objectives, usage scenarios, and raw material characteristics of the organic fertilizers. When the organic fertilizer mixing device is working, the controller regulates the rotation state of the material feeding shaft based on the third motor, and can achieve quantitative feeding of materials. However, this control method is greatly affected by external factors such as material fluidity, humidity, and particle size, and has low control accuracy. Although it can meet the needs of general organic fertilizer production, for the production of high-end products or organic fertilizers for some specific purposes, it reflects the deficiency of poor mixing ratio control accuracy; for this reason, the organic fertilizer mixing device provided by the present invention also includes the following technical features:

[0036] See also Figure 6 As shown, a connecting portion 21 is fixed at the center of the upper side of the loading tray 9, and the loading tray 9 is connected to the main shaft 6 via the connecting portion 21; the connecting portion 21 and the main shaft 6 are slidably matched in the vertical direction, and the two cannot rotate relative to each other; a weighing sensor 19 is fixed on the main shaft 6, and the connecting portion 21 is supported in the vertical direction by the weighing sensor 19, and the weighing sensor 19 can feed back weighing data to the controller, and the controller can calculate the weight change of the material in the loading tray 9 based on the weighing data fed back by the weighing sensor 19; therefore, when the controller enables a third motor to run alone, the controller can calculate the weight change of the material in the loading tray 9 according to the weighing data, that is, obtain the amount of the corresponding material put in, and this control method is no longer affected by external factors such as material fluidity, humidity and particle size, so that more precise control can be achieved for the quantitative feeding of materials;

[0037] Based on the above quantitative delivery control principle, when multiple materials are quantitatively delivered, each material can be delivered one by one to achieve precise control of the delivery amount and improve the accuracy of the material mixing ratio;

[0038] In addition, when the above-mentioned quantitative delivery control principle is used to accurately deliver a variety of materials, the loading plate is kept rotating, and each material is delivered quantitatively in a reciprocating cycle, and the technical effect of premixing the materials can still be achieved.

[0039] Furthermore, the connecting portion and the main shaft can achieve sliding fit through a variety of matching structural modes, and the preferred matching mode is:

[0040] like Figure 6 , Figure 7 As shown, a vertically extending column cavity is provided in the middle and lower part of the main shaft 6, the connecting part 21 is a sliding column, the middle and upper part of the connecting part 21 is inserted into the column cavity and the two are slidably matched, side holes 22 are provided on both sides of the column cavity, a cross arm 20 is fixed on the connecting part 21, and the two ends of the cross arm 20 extend to the outside of the main shaft 6 through the two side holes 22; two weighing sensors 19 are provided, which are respectively fixed on both sides of the main shaft 6 and located at the lower side of the cross arm 20, and the two ends of the cross arm 20 are respectively against the pressure-bearing ends of the two weighing sensors 19, so that the load of the connecting part 21 in the up and down directions is jointly borne by the pressure-bearing ends of the two weighing sensors 19;

[0041] Based on this matching structure, the main shaft can not only provide stable support and driving effect for the loading plate, but also ensure that the force applied by the cross arm to the weighing sensor tends to coincide with the force axis of the weighing sensor, thereby reducing the influence of the inclined load and eccentric load on the accuracy of the weighing data during the operation of the loading plate, thereby improving the accuracy of the weighing data.

[0042] Preferably, the organic fertilizer mixing device disclosed in this embodiment may also include one or more of the following technical features:

[0043] See also Figure 8 , Fig. 9 As shown, the loading tray is a shell structure, including a cylinder 95 with a cylindrical main body profile, the interior of the cylinder 95 is divided by a plurality of vertical plates 91 to form a plurality of bins, the lower end of the bin is an inclined bottom plate, so that the materials in the bin can be gathered at the lowest end to facilitate discharge, a hollow vertical pipe 92 is provided in the center of the loading tray, the vertical plates 91 and the bottom plate 93 in the cylinder 95 are fixedly connected to the vertical pipe 92, and a plurality of reinforcing ribs 96 extending radially and arranged at equal angles are fixedly provided on the upper side of the loading tray, and the reinforcing ribs 96 are fixedly connected to the vertical pipe 92 and the cylinder 95; thereby, the dead weight of the loading tray can be significantly reduced, and the overall structure of the loading tray is ensured to have good stability, and can stably carry the materials to be mixed;

[0044] See also Figure 8 , Fig. 9As shown, a feeding trough 94 communicating with the hopper is fixed at the lower end thereof, and the feeding trough 94 extends horizontally along the radial direction of the loading plate; the feeding port 15 is provided on the lower side wall of the feeding trough 94, and the material-dispensing shaft and its material-dispensing components are arranged in the corresponding feeding trough; when feeding, the material in the hopper first enters the feeding trough 94, and can have a more complete contact with the material-dispensing components in the feeding trough 94, so that the material can be more evenly fed into the stirring device through the feeding port 15, which also helps to improve the effect of breaking the agglomerates;

[0045] See also Fig.10 As shown, the organic fertilizer mixing device disclosed in this embodiment also includes a feeding device, which includes a hopper 23 and a conveying mechanism 24 for conveying the material in the hopper 23 upward, and the discharge end of the conveying mechanism 24 is located on the upper side of the silo 8 in the loading tray 9, and the conveying mechanism 24 is an auger conveying device or a conveyor belt conveying device; since the loading tray 9 can rotate, the position of the silo 8 can be adjusted, thereby different materials can be conveyed to the corresponding silo 8 by means of the feeding device in cooperation with the rotation of the loading tray 9.
