Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of organic fertilizer particle forming, and specifically relates to a pollution-free pear and vegetable organic fertilizer forming device. Background Art
[0002] If the spacing between pear trees is too large for large-scale planting, the yield will be small and the cost recovery period will be long. If the spacing between plants is too large, there will be competition for nutrients. Densely planted pear trees occasionally show pathological symptoms such as short plants, thin branches, slow growth, few leaves, dull color, and few flower buds. Prevent this by applying organic fertilizer in advance.
[0003] Organic fertilizer is made by putting the mixed materials into a granulator and processing them into granules for easy packaging and fertilization. According to the processing method, traditional granulators can be divided into: double-roller extrusion granulator, disc rotary granulator, drum granulator, flat die extrusion granulator, double membrane granulator, etc.
[0004] The flat die extrusion granulator produces organic fertilizer by discharging the extruded materials from the lower hopper together. The materials can be screened in the lower hopper, and the screening point is often fixed at the lower hopper. The sieve holes have large spacing, which can easily deviate from and stagger some powdered materials, which is not conducive to improving the recovery rate of powder in the product. Therefore, we propose a pollution-free pear and vegetable organic fertilizer forming device. Utility Model Content
[0005] The purpose of the utility model is to provide a pollution-free pear and vegetable organic fertilizer forming device, which can separate particles and residual powder during rotation and movement, increase the contact frequency between the residual powder and these holes, and is conducive to improving the recovery rate of the powder in the product.
[0006] The technical solutions adopted in this utility are as follows:
[0007] A pollution-free pear and vegetable organic fertilizer forming device comprises a particle forming machine body, a discharge port is provided on one side of the particle forming machine body, an annular slide rail and a collecting plate are fixed to the outside of the particle forming machine body in sequence from top to bottom, the height of the annular slide rail is not greater than the height of the discharge port, a coaxial sieve plate is slidably mounted on the outside of the annular slide rail, a baffle is slidably mounted on the outside of the sieve plate, a rotating mechanism for rotating the sieve plate is fixed to the outside of the baffle, the baffle is in a "C" shape, the middle of the collecting plate is downwardly concave in an annular shape, and when working, raw materials are added to the particle forming machine body. The pellets and residual powder are discharged from the discharge port after extrusion molding and fall onto the screen plate. At the same time, the screen plate is rotated along the annular slide rail by the rotating mechanism, driving the pellets and residual powder on the screen plate to rotate. Under the action of centrifugation, they continue to move away from the pellet molding machine body. The residual powder will fall when it encounters the holes in the screen plate and fall into the collecting tray for collection, while the pellets will contact the enclosure until they are discharged along the opening of the "C" shaped structure. The pellets and residual powder are separated during the rotating movement, increasing the contact frequency between the residual powder and these holes, which is beneficial to improving the recovery rate of the powder in the product.
[0008] The rotating mechanism includes a rotating motor fixed on the outside of the enclosure, the output end of the rotating motor extends to the bottom of the sieve plate and is fixed with a roller, the upper surface of the roller contacts the lower surface of the sieve plate and can be adjusted according to the amount of particles. For example, when there are many particles, the speed of the rotating motor is reduced to drive the roller to rotate the sieve plate at a low speed to prevent the particles above from being thrown away. When there are fewer particles, the speed of the rotating motor is increased to drive the roller to rotate the sieve plate at a high speed, so that the particles have enough space to move and are rarely thrown away.
[0009] A rubber ring is fixed on the contact surface between the roller and the sieve plate, and the deformation of the rubber ring is used for buffering. The roller and the sieve plate can be interference fit to prevent the roller from separating from the sieve plate.
[0010] An anti-sticking film in contact with the sieve plate is fixed on the inner side of the enclosure. The anti-sticking film can be made of a polyurethane film to isolate the particles from the enclosure and reduce the raw materials or particles adhering to the enclosure.
[0011] A plurality of columns are fixed at intervals on the lower edge of the enclosure, and the columns are all in an inverted "V"-shaped structure and can be erected on the ground. The multi-point enclosure and its triangular structure provide better support stability.
[0012] There are several small barrels distributed in a circular array inside the annular depression of the collecting plate. After the powder passes through the holes of the sieve plate, it falls into the small barrels of the collecting plate below until the small barrels are full. When the powder is collected to a certain level, the small barrels can be taken out uniformly, the powder can be recovered and poured into the main body of the granulator for secondary extrusion molding. The barrels with less powder do not need to be taken out and wait for the next time to be taken out.
[0013] The technical effects achieved by this utility model are:
[0014] The present invention is a practical pollution-free pear and vegetable organic fertilizer forming device. When working, raw materials are added into a particle forming machine body, and after extrusion forming, the particles and residual powder are discharged from a discharge port and fall onto a screen plate. At the same time, a rotating mechanism rotates the screen plate along an annular slide rail, driving the particles and residual powder on the screen plate to rotate, and continuously move in a direction away from the particle forming machine body under the action of centrifugation. The residual powder will fall when it encounters the holes of the screen plate and fall into a collecting plate for collection, while the particles will contact the enclosure until they are discharged along the opening of a "C"-shaped structure. The particles and residual powder are separated during the rotating movement, and the contact frequency of the residual powder with the holes is increased, which is beneficial to improving the recovery rate of the powder in the product.

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.
[0022] like Figure 1-4As shown, a pollution-free pear and vegetable organic fertilizer forming device comprises a particle forming machine body 1, a Chinese utility model with reference announcement number CN220610251U, an organic fertilizer particle forming device, which can be purchased from the market. A flat die extrusion granulator produced by Zhengzhou Tianci Heavy Industry Machinery Co., Ltd. has an operating voltage of 380V, a reducer is used, and a speed of 970r / min is used. The output particle diameter is 3-5mm, and a discharge port 2 is provided on one side of the particle forming machine body 1. An annular slide rail 3 and a collecting plate 6 are fixed to the outer side of the particle forming machine body 1 from top to bottom in sequence. The height of the annular slide rail 3 is not greater than the height of the discharge port 2. The inner side of the annular slide rail 3 is fixedly connected to the outer side of the particle forming machine body 1. A coaxial sieve plate 4 is slidably installed on the outer side of the annular slide rail 3. The sieve plate 4 is a porous annular plate structure with an aperture of not more than 3mm. The outer side of the sieve plate 4 A baffle 5 is slidably installed, and the baffle 5 can be grounded by supporting measures. A rotating mechanism for rotating the sieve plate 4 is fixed on the outside of the baffle 5. The baffle 5 is in a "C" shape, and the collecting plate 6 is annularly depressed downward in the middle. When working, the raw material is added to the particle forming machine body 1, and the particles and residual powder are discharged from the discharge port 2 after extrusion molding, and fall onto the sieve plate 4. At the same time, the sieve plate 4 is rotated along the annular slide rail 3 by the rotating mechanism, driving the particles and residual powder on the sieve plate 4 to rotate, and continuously move away from the particle forming machine body 1 under the action of centrifugation, and the residual powder will fall when encountering the holes of the sieve plate 4, and fall into the collecting plate 6 for collection, and the particles will contact the baffle 5 until they are discharged along the opening of the "C" shape structure, and the particles and residual powder are separated during the rotating movement, increasing the contact frequency of the residual powder with these holes, which is beneficial to improving the recovery rate of the powder in the product.
[0023] Among them, the sieve plate 4 has a radially decreasing slope, which makes it easy for the particles to slide down directly along the slope and will not stay on the sieve plate 4, and can also reduce the difficulty of the powder sliding down. Moreover, the holes of the sieve plate 4 have rounded corners, which will not obviously cut the particles, making it convenient to maintain the roundness of the particles. The sieve plate 4 is also sprayed with an anti-stick coating.
[0024] like Figure 1 and Figure 4 As shown, the rotating mechanism includes a rotating motor 7 fixed on the outside of the enclosure 5. The rotating motor 7 can be purchased as a three-phase asynchronous motor from the market and can be matched with a distribution box for speed regulation. The output end of the rotating motor 7 extends to the bottom of the sieve plate 4 and is fixed with a roller 8. The upper surface of the roller 8 contacts the lower surface of the sieve plate 4 and can be adjusted according to the amount of particles. For example, when there are many particles, the speed of the rotating motor 7 is reduced to drive the roller 8 to rotate the sieve plate 4 at a low speed to prevent the particles above from being thrown away. When there are fewer particles, the speed of the rotating motor 7 is increased to drive the roller 8 to rotate the sieve plate 4 at a high speed. The particles have enough space to move and are rarely thrown away.
[0025] like Figure 1 and Figure 4As shown, a rubber ring 9 is fixed on the contact surface between the roller 8 and the sieve plate 4 , and the deformation of the rubber ring 9 is used for buffering. The roller 8 and the sieve plate 4 can be interference fit to prevent the roller 8 from separating from the sieve plate 4 .
[0026] like Figure 1 and Figure 2 As shown, an anti-sticking film 10 in contact with the sieve plate 4 is fixed to the inner side of the enclosure 5 . The anti-sticking film 10 can be made of a polyurethane film to isolate the particles from the enclosure 5 and reduce the raw materials or particles adhering to the enclosure 5 .
[0027] like Figure 1 and Figure 2 As shown, a plurality of columns 11 are fixed at intervals on the lower edge of the enclosure 5. The columns 11 are all in an inverted "V"-shaped structure and can be erected on the ground. The multi-point enclosure 5 has a triangular structure and has better support stability.
[0028] like Figure 1 and Figure 3 As shown, a plurality of small barrels 12 are distributed in a circular array inside the annular depression of the collecting plate 6. After the powder passes through the holes of the sieve plate 4, it falls into the small barrels 12 of the collecting plate 6 below until the small barrels 12 are almost full. When the powder is collected to a certain level, the small barrels 12 can be taken out uniformly, the powder can be recovered, and poured into the granulator body 1 for secondary extrusion molding. The small barrels 12 with less powder do not need to be taken out and wait for the next time to be taken out.
[0029] The working principle of the utility model is as follows: when working, the raw materials are added into the particle forming machine body 1, and the particles and residual powder are discharged from the discharge port 2 after extrusion forming and fall onto the sieve plate 4, and at the same time, the sieve plate 4 is rotated along the annular slide rail 3 by the rotating mechanism, driving the particles and residual powder on the sieve plate 4 to rotate, and continuously move in the direction away from the particle forming machine body 1 under the centrifugal action, and the residual powder will fall when it encounters the holes of the sieve plate 4 and fall into the collecting plate 6 for collection, while the particles will contact the enclosure 5 until they are discharged along the opening of the "C"-shaped structure, and the particles and residual powder are separated during the rotating movement, thereby increasing the contact frequency of the residual powder with these holes, which is beneficial to improving the recovery rate of the powder in the product.
[0030] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
