Description

TECHNICAL FIELD

[0001] The utility model relates to the field of organic fertilizer production, and particularly relates to a granulating device for organic fertilizer with quantitative feeding. BACKGROUND

[0002] During the growth of grain, fertilizers are needed to supplement various trace elements required for growth, wherein the manure of cattle, sheep, pigs and chickens is rich in trace elements required for plant growth and can be reused to produce organic fertilizer through fermentation. The fermented fertilizer needs to be granulated during processing to facilitate subsequent packaging and transportation. A disc granulator is used in this process. The disc granulator is a type of granulator, and has the advantages of uniform granulation, high granulation rate, stable operation, solid and durable equipment, long service life and the like, and is an ideal granulation equipment.

[0003] At present, the production of granular organic fertilizer mostly adopts a whole-process fully mechanized production mode, but this production mode has high cost. Most small-scale organic fertilizer production enterprises mostly use manual or bucket trucks to transport the fermented dry organic fertilizer to the starting end of the conveying belt, and then use the conveying belt to transport the organic fertilizer to the disc granulator during the granulation of the organic fertilizer.

[0004] However, during the production process, it is found that the total amount of material transported each time is not consistent when the organic fertilizer material is manually or by bucket truck transported to the starting end of the conveying belt, and the material is not accurately delivered to the most suitable area at the starting end of the conveying belt. Since the material is relatively dry before granulation and is transported from low to high, the position of the material on the conveying belt is affected by factors such as gravity and friction, for example, during the lifting process, the material above slides down to a certain section and then accumulates into a small group, and the gravity and friction coincide to reach a balance, which causes the material to accumulate in a certain section. As a result, there is more material in some sections of the conveying belt and less material in some sections due to sliding, so the material on the conveying belt is in a non-uniform transportation state. As a result, a problem arises. The disc granulator needs to be watered to wet the material before granulation, and continuous material conveying requires continuous spraying. Since the material fed into the disc granulator on the conveying belt is not uniformly fed, and the spraying is continuous and stable, the total amount of water and organic fertilizer raw material cannot be in a fixed ratio at intervals, which causes some organic fertilizer granules to be too large or too small in size. To solve this problem, additional screening is required, and then the unqualified products need to be dried and crushed again for granulation, which increases the production cost and reduces the granulation efficiency.

[0027] As shown in Figure 1 Figure 2 and Figure 3 The quantitative feeding mechanism 5 includes the support assembly of vertical fixed connection in the bottom of conveying belt 4 along the conveying direction and the square receiving tank 55 of rotation connection with support assembly, the receiving tank 55 includes the bottom plate 552 and the side plate 551 around three sides of bottom plate 552, the side plate 551 can select two opposite rectangular plates to cooperate another rectangular plate and enclose three sides of bottom plate 552, and one side of bottom plate 552 is not provided with side plate 551 and horizontally faces the top area of disc granulator, and another side corresponds to the material outlet end, and two sides cooperate to form an open end, so that the whole square receiving tank 55 is in the shape of a scoop.The material outlet end of conveying belt 4 is arranged at the top area above the open end of receiving tank 55, and conveying baffle 41 is further arranged on the material outlet end for limiting the falling direction of the material, so that the material can fall into receiving tank 55, and after the material falling from the open end enters receiving tank 55 and reaches a certain total amount, receiving tank 55 is turned over towards disc granulator 2, and the material falls into disc granulator 2 from the open end.

[0028] like Figure 1 、 Figure 2 and Figure 3 As shown, the quantitative unloading mechanism 5 also includes a return component for controlling the flipping and returning of the receiving box 55. The return component is arranged in conjunction with the receiving box 55 and controls the receiving box 55 not to flip over before receiving the quantitative material. After the receiving box 55 receives the quantitative material and flips over to unload, the return component returns the receiving box 55 from the flipped state. The return component includes a counterweight block 56 fixed to the edge of the bottom plate 552 of the receiving box 55 in a partial top area. The counterweight block 56 is arranged in the edge area on the other side of the bottom plate 552 opposite to the open end of the receiving box 55. The counterweight block 56 is opposite to the position of the open end. The center of gravity of the receiving box 55 is concentrated on the counterweight block 56, so that it can be used to receive the material. After the box 55 is flipped, the position of the material receiving box 55 is returned to its original position, and then the material is continued to be received. In order to prevent the counterweight block 56 from causing the material receiving box 55 to return excessively, a connecting rod 561 is also rotatably provided on the counterweight block 56. The rotating surface of the connecting rod 561 is a vertical surface and the central axis of the rotating surface is perpendicular to the conveying direction, so that when the connecting rod is rotated to any angle, its extension line intersects with the conveying direction, and the end of the connecting rod 561 away from the counterweight block 56 is slidably set on the support side plate 52; when the material receiving box 55 is flipped, when the counterweight block 56 is displaced to rise or fall, one end of the connecting rod 561 is displaced and slid on the support side plate, and the flipping angle of the material receiving box 55 is limited by the sliding distance.

[0029] Further, such as Figure 1 and Figure 2 As shown, the support assembly includes a support frame 51 vertically fixed on both sides of the conveyor belt 4 along the conveying direction, and also includes a support side plate 52 vertically connected to the bottom of the support frame, the support side plate 52 is arranged along the conveying direction, and the support side plate 52 is close to the end of the discharge end of the conveyor belt 4 and is also protruding with a connecting bracket 54, and the connecting bracket 54 is transferred to the side of the open end of the material receiving box 55. Through the above structure, the quantitative unloading mechanism 5 is fixed to the discharge end of the conveyor belt 4, so that the material receiving box 55 is suspended in the area below the discharge end of the conveyor belt 4 to uniformly collect the unevenly distributed materials on the conveyor belt 4, and reach a fixed total amount, and then flip and discharge them into the disc granulator 2 under the support of the connecting bracket 54.

[0030] Further, such as Figure 2 and Figure 3 As shown, a rotating shaft 553 is further provided on the outer surface of the opposite side plate 551, and a corresponding bearing 541 is provided on the end of the connecting bracket 54. The opposite side plate 551 is connected to the corresponding connecting bracket 54 by means of the bearing 541, and the rotating shaft 553 set on the side plate 551 of the material receiving box 55 is connected by means of the bearing 541 set on the connecting bracket 54, so as to realize the flipping of the material receiving box 55 within a limited range.

[0031] Further, as shown in Figure 2 and Figure 3 , the support side plate 52 is provided with a sliding groove 53 along the conveying direction, the end of the connecting rod 561 away from the counterweight 56 is vertically provided with a sliding rod 562, the middle part of the sliding rod 562 is vertically fixedly connected with the end of the connecting rod 561, the sliding rod 562 is T-shaped with the connecting rod 561, and the two ends of the sliding rod 562 are slidingly connected in the two sliding grooves 53. When the material receiving box 55 receives material, the gravity of the counterweight 56 cooperates with the connecting rod 561 at the proximal end of the sliding groove 53, on the one hand, the material receiving box 55 cannot be turned over in advance before receiving a total amount of material sufficient to turn over and discharge forward, and on the other hand, the connecting rod 561 cooperates with the sliding rod 562 at the position of the sliding groove 53 opposite the proximal end of the material receiving box 55, pulls the counterweight 56, so that the gravity of the counterweight 56 cannot make the material receiving box 55 continue to turn over backward. After the material receiving box 55 continues to receive material, because the position of the material falling from the discharging end of the conveying belt 4 is close to the side of the opening of the material receiving box 55, when enough material is received, the internal weight breaks the balance, the material receiving box 55 turns over in the direction of the disc granulator 2, and the sliding rod 562 slides toward the distal end of the sliding groove 53 under the pushing of the connecting rod 561. At this time, when the material receiving box 55 turns over to a certain angle, the sliding rod 562 abuts against the position of the sliding groove 53 opposite the distal end of the material receiving box 55, the bottom of the connecting rod 561 and the position of the counterweight 56 are turned to the maximum angle, and the counterweight 56, the connecting rod 561 and the sliding groove 53 interfere with each other. Under the action of the gravity of the counterweight 56, the material receiving box 55 is reset, then the sliding rod 562 slides to the proximal end of the sliding groove 53 and is limited by the sliding groove 53, the connecting rod 561 limits the continuous displacement of the counterweight 56 to descend, and then the above operation is repeated.

The spraying head 32 is arranged above the disc granulator 2 and below the area of the bottom plate 552 of the material receiving box 55 through the pipeline 31. The spraying head 32 is arranged below the area of the bottom plate 552 of the material receiving box 55, so that when the spraying head 32 stops spraying, the residual water droplets cannot wet the material receiving box 55, so that the material receiving box 55 remains dry, and the material received by the material receiving box 55 is prevented from being wetted by water and adhered to the material receiving box 55.

[0033] Further, as shown in Figure 2 , Figure 3 and Figure 4As shown, the quantitative discharging mechanism further comprises a signal sensing device 57, the spraying assembly 3 comprises a control panel 35, the signal sensing device 57 is signal connected with the control panel 35 and detects the signal transmitted by the control panel 35 after the receiving box 55 is tilted to discharge, so as to control the spraying assembly 3 to spray.

[0034] The signal sensing device 57 comprises a signal processing transmitter arranged on the support frame 51 and a touch sensor 571 arranged on the top of the chute 53, the water pump 33 is further provided with the control panel 35 to receive the signal transmitted by the signal processing transmitter, the touch sensor 571 is electrically connected with the signal processing generator through an electric circuit 572 and is signal connected with the control panel 35, when the receiving box 55 is turned to discharge, the slide rod 562 passes through the touch sensor 571 on the top of the chute 53, the signal processing transmitter transmits the signal to the control panel 35 through wireless signal, the control panel 35 controls the water pump 33 to start spraying according to the pre-set time, so that the material turned by the receiving box 55 and the water form a fixed proportion, preventing the granulation product from being too large or too small due to too much or too little water.

[0035] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited.
