[0001] The invention relates to the field of raw material transportation, and more specifically, to a quantitative feeder for an organic fertilizer production line. Background Art

[0002] The quantitative feeder is a mechanical equipment for continuous weighing, calculation and quantitative conveying of solid bulk materials. It is widely used in chemical industries such as cement, mining, and fertilizer manufacturing. It is known for its advanced technology, stability, reliability, and durability. It is an automated high-tech mechanical product. The quantitative feeder for organic fertilizer production lines is a key equipment designed specifically for organic fertilizer production lines. It is used for precise and quantitative feeding to ensure the continuous and stable operation of the production line.

[0003] When the drive motor starts, it drives the conveyor belt to rotate at a stable speed. The raw materials are introduced into the conveyor belt through the feed port and transported to the next production link as the conveyor belt moves.

The width of the discharge port of each feeding mechanism is finely regulated to ensure that the raw materials fall onto the conveyor belt according to the preset layers and sequence, thereby realizing efficient and accurate quantitative feeding.

[0020] A shoveling mechanism is designed directly below each discharge mechanism. As the conveyor belt rotates, the shoveling mechanism scoops up the material and drops it back onto the conveyor belt. In this process, the downward pressure of the material on the surface of the shoveling mechanism is used to measure the weight of the material discharged by the first discharge mechanism. Once the measured weight is less than the preset value, it indicates that the raw materials may be agglomerated or adsorbed at the outlet of the discharge mechanism. At this time, the inner wall of the discharge port of the discharge mechanism is controlled to shake, effectively shaking off the agglomerated and adsorbed raw materials to prevent blockage and ensure the continuity and accuracy of material discharge.

[0033] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 , as shown, a quantitative feeder for an organic fertilizer production line comprises a feeder body 11, a conveyor belt 13 for circulating material is laid on the surface of the feeder body 11, a driving motor 12 for driving the conveyor belt 13 to rotate is arranged on one side of the feeder body 11, a feed port 14 is arranged on one end of the conveyor belt 13, a plurality of groups of discharge mechanisms 2 are arranged inside the feed port 14, and a shoveling mechanism 3 is arranged directly below each group of discharge mechanisms 2;

[0035] By integrating four feeding mechanisms 2 of the same specifications into the feeding port 14, the feeding amount and proportion of different raw materials of organic fertilizer can be accurately controlled. The width of the discharge port of each feeding mechanism 2 is finely regulated to ensure that the raw materials fall onto the conveyor belt 13 according to the preset layers and sequence, thus realizing efficient and accurate quantitative feeding;

[0036] A shoveling mechanism 3 is designed directly below each discharge mechanism 2. As the conveyor belt 13 rotates, the shoveling mechanism 3 scoops up the material and drops it back onto the conveyor belt 13. During this process, the downward pressure of the material on the surface of the shoveling mechanism 3 is used to measure the weight of the material discharged by the first discharge mechanism 2. Once the measured weight is less than the preset value, it indicates that the raw materials may be agglomerated or adsorbed at the outlet of the discharge mechanism 2. At this time, the inner wall of the discharge port of the discharge mechanism 2 is controlled to shake, so as to effectively shake off the agglomerated and adsorbed raw materials, prevent blockage, and ensure the continuity and accuracy of material discharge.

[0037] like Figure 2 , Figure 5 , Figure 8 and Fig. 9 As shown, the shoveling mechanism 3 includes a weighing piece and a supporting mechanism 4. The weighing piece includes a lifting plate 31 with an inclined structure. A feeding belt 32 is rotatably arranged inside the lifting plate 31. A pressure measuring liquid box 33 is arranged inside the feeding belt 32. The infusion end of the pressure measuring liquid box 33 is connected to the supporting mechanism 4.

[0038] like Figure 6 , Figure 7 and Figure 8 As shown, the discharge mechanism 2 includes a wall pushing member and a quantitative material control plate 23. A soft rubber wall 28 is fixedly embedded on the unloading side of the quantitative material control plate 23. A pushing wall is arranged on the inner side of the soft rubber wall 28. With the rotation of the conveyor belt 13, the material falling from the quantitative material control plate 23 is scooped up and moved along the feeding belt 32. The feeding belt 32 is pressed downward by the material, and the feeding belt 32 squeezes the pressure measuring liquid box 33 to measure the weight of the material, and controls the wall pushing member to push the soft rubber wall 28 to expand and contract according to the measurement result through the supporting mechanism 4.

[0039] like Figure 7 , Figure 8 and Fig. 9 As shown, the weighing piece also includes two belt-drawing columns 34 rotatably connected to the starting plate 31. The two belt-drawing columns 34 are respectively distributed at the two ends of the feeding belt 32 and meshed with the feeding belt 32. The two ends of the belt-drawing columns 34 close to the conveyor belt 13 are meshed with toothed belts 37. A rack 5 meshing with the toothed belt 37 is provided under the starting plate 31, and the toothed belt 37 is rotatably connected to the starting plate 31.

[0040] The pressure measuring fluid box 33 includes a plurality of top columns 35 penetrating the upper wall of the pressure measuring fluid box 33, the top end of the top column 35 is an inclined surface, and the inclined surface of the top column 35 is in contact with the inner wall of the feeding belt 32, and the inner wall of the pressure measuring fluid box 33 is fixedly provided with a plurality of elastic sealing films 36, and the plurality of sealing films 36 correspond one-to-one to the plurality of top columns 35, and the output end of the pressure measuring fluid box 33 is connected to an infusion tube 38.

[0041] First, the staff needs to add various raw materials for processing organic fertilizer into four material distribution boxes 21 respectively. The raw materials fall onto the conveyor belt 13 through the adjusted quantitative control plate 23. As the conveyor belt 13 rotates, the materials move. Then, the materials are scooped up by the lifting plate 31 and gradually pushed onto the feeding belt 32.

[0042] The rack 5 rotates at the same speed and in the same direction through the rotation of the conveyor belt 13, the toothed belt 37 is driven to rotate through the rack 5, the belt pulling column 34 is driven to rotate through the toothed belt 37, and the feed belt 32 rotates in the same direction as the conveyor belt 13 through the rotation of the belt pulling column 34, so that the material is gradually transported to a higher place through the feed belt 32;

[0043] First, the material accumulated on the upper surface of the feeding belt 32 presses down the feeding belt 32, and the feeding belt 32 is pressed down by the material and simultaneously presses down a number of top pillars 35, so that the top pillars 35 retract to squeeze the sealing film 36. At this time, the heavier the material on the upper surface of the feeding belt 32, the longer the top pillars 35 retract to the pressure measuring liquid box 33, and the more water in the pressure measuring liquid box 33 is squeezed out. If the material on the feeding belt 32 is always kept at a specified value, the water squeezed out of the pressure measuring liquid box 33 is always kept at a specified value. If the weight of the material on the feeding belt 32 is less than the specified value, the amount of water squeezed out of the pressure measuring liquid box 33 is reduced, which indicates that the quantitative control plate 23 of the discharge port of this material distribution box 21 is agglomerated, causing blockage;

[0044] Secondly, after the materials on the upper surface of the feeding belt 32 are transported to a high place, they fall back onto the conveyor belt 13, so that the materials discharged from the multiple material distribution boxes 21 are mixed, thus playing the role of mixing materials;

[0045] like Fig. 9 , Fig.10 and Fig.11 As shown, the supporting mechanism 4 includes a regulating box 41, the interior of the regulating box 41 is divided into two unconnected spaces, namely a regulating window 42 and a liquid inlet box 43, and two identical lifting blocks 44 and 45 are slidingly arranged inside the regulating window 42. The lifting blocks 44 and 45 are fixedly connected by a connecting column, and a guide column 46 is provided at the center position of the lifting blocks 44 and 45.

[0046] The lifting block 1 44 and the lifting block 2 45 are fixedly provided with electromagnetic switches 2 48 and 1 49 on one side close to the liquid inlet box 43, and the upper wall of the lifting block 1 44 is fixedly provided with a linkage control rope 26. The connecting ends of the electromagnetic switches 2 48 and 1 49 are both connected with wires.

[0047] A floating plate 401 is slidably disposed inside the liquid inlet box 43, and a magnetic sheet 402 is fixedly disposed on one side of the floating plate 401 close to the regulating window 42. The center lines of the magnetic sheet 402, the second electromagnetic switch 48 and the first electromagnetic switch 49 are aligned with each other.

[0048] The water squeezed out of the pressure measuring liquid box 33 flows into the liquid inlet box 43 through the infusion tube 38, and the water flows into the liquid inlet box 43 from the bottom. As the amount of water in the liquid inlet box 43 increases, the upper floating plate 401 floats up. If the discharge amount of the corresponding material distribution box 21 is maintained at a specified value, the material on the feeding belt 32 is always maintained at a specified value, and the water squeezed out of the pressure measuring liquid box 33 is always maintained at a specified value. The water surface flowing into the liquid inlet box 43 is between the lifting block 1 44 and the lifting block 2 45, so that the upper floating plate 401 floats between the lifting block 1 44 and the lifting block 2 45.

[0049] If the weight of the material on the feeding belt 32 is less than the specified value, the amount of water squeezed out of the pressure measuring liquid box 33 is reduced, and the water level of the liquid inlet box 43 drops, and the upper floating plate 401 drops accordingly, and the magnetic sheet 402 is close to the position of the electromagnetic switch 49. At this time, the electromagnetic switch 49 controls the electromagnet 206 to work;

[0050] If the weight of the material on the feeding belt 32 is greater than the specified value, the amount of water squeezed out of the pressure measuring liquid box 33 increases, and the water level of the liquid inlet box 43 rises, and the upper floating plate 401 rises accordingly, and the magnetic sheet 402 approaches the position of the electromagnetic switch 48. At this time, the electromagnetic switch 48 controls the electric push rod 25 to work;

[0051] The electromagnetic switch 1 49 is connected to the electromagnet 206 through a wire, and the electromagnetic switch 2 48 is connected to the electric push rod 25 through a wire;

[0052] The material discharging mechanism 2 also includes a material distribution box 21, in which an inner support plate 22 is fixedly arranged, and the inner support plate 22 is rotatably connected to a quantitative material control plate 23, and a protective wall 205 is fixedly arranged on the side of the connection end between the inner support plate 22 and the quantitative material control plate 23 close to the material flow.

[0053] A joint control plate 24 is fixedly provided on the side of the quantitative material control plate 23 away from the material flow, and a plurality of arc-shaped spring pieces 27 are slidably provided on the side of the joint control plate 24 away from the quantitative material control plate 23. The plurality of spring pieces 27 are fixedly connected to the wall panel of the material distribution box 21, and an electric push rod 25 is provided between the inner support plate 22 and the joint control plate 24, and the inner support plate 22 is fixedly connected to the electric push rod 25.

[0054] The wall pushing member includes a plurality of wall pushing plates 29, and the plurality of wall pushing plates 29 are slidably arranged between the soft rubber wall 28 and the quantitative material control plate 23. The uppermost wall pushing plate 29 of the plurality of wall pushing plates 29 is rotatably provided with a linkage arm 201 at both ends, and a transmission plate 207 is fixedly provided at one end of the linkage arm 201 away from the wall pushing plate 29. The connection point between the linkage arm 201 and the wall pushing plate 29 is located at three quarters of the wall pushing plate 29.

[0055] A rotating column 202 is rotatably arranged between the tops of the two transmission plates 207, a rotating column 203 is rotatably arranged between the bottoms of the two transmission plates 207, a pulling column 204 is arranged at the center of the rotating column 203, and an electromagnet 206 is fixedly arranged at one end of the pulling column 204 away from the rotating column 203.

[0056] Before the material is added to the distribution box 21, the electric push rod 25 is controlled to drive the joint control plate 24 to rotate, and the joint control plate 24 drives the quantitative control plate 23 to rotate counterclockwise, thereby adjusting the unloading space on one side of the quantitative control plate 23, so as to play the role of quantitative discharge. The distribution boxes 21 are each responsible for quantitatively feeding different raw materials of organic fertilizer onto the conveyor belt 13. By finely adjusting the unloading space on one side of each quantitative control plate 23, the feeding amount of the raw materials can be accurately controlled to ensure that each raw material can fall onto the conveyor belt 13 according to the preset proportion and sequence. In this orderly feeding process, the first feeding mechanism 2 will first feed the raw material onto the conveyor belt 13, and then the second feeding mechanism 2 will cover the raw material of the first feeding mechanism 2 with a new layer of raw material, and so on, forming a layered raw material superposition effect. This design not only improves the mixing uniformity of the raw materials, but also ensures the accuracy and efficiency of the entire feeding process.

[0057] The telescopic column of the electric push rod 25 is fixedly connected to the joint control rope 26. The longer the electric push rod 25 is telescopic, the longer the length of the joint control rope 26 is loosened, and the height of the lifting block 1 44 and the lifting block 2 45 is lower, thereby cooperating with the shoveling mechanism 3.

[0058] like Figure 5 and Figure 6As shown, when the electromagnet 206 is working, the pulling column 204 is pulled, and the rotating column 203 is pulled by the pulling column 204 to rotate with the rotating column 1 202 as the center. The two ends of the rotating column 1 202 pass through the transmission plate 207 and are fixedly connected to the fixed plate of the feeder body 11. The pushing plate 29 is driven to rotate downward through the linkage arm 201, thereby pushing the soft rubber wall 28 to bulge, so that the lumps on the surface of the soft rubber wall 28 are shaken off. Because the connection point between the linkage arm 201 and the pushing plate 29 is located at three-quarters of the pushing plate 29, when the linkage arm 201 pushes the pushing plate 29 to slide downward for a distance, the upper side edges of the pushing plate 29 are elastically squeezed by the soft rubber wall 28, so that the lower side edges of the pushing plate 29 are pushed by the linkage arm 201, which plays a role in lifting the pushing plate 29 and causing the soft rubber wall 28 to bulge.

[0059] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
