Description

Technical Field

[0001] The invention relates to the field of organic fertilizer production and processing equipment, in particular to a screening device for organic fertilizer processing. Background Art

[0002] Organic fertilizer refers to carbon-containing materials that are mainly derived from plants and (or animals) and applied to the soil to provide plant nutrition as its main function. It is processed from biological materials, animal and plant waste, and plant residues, and eliminates toxic and harmful substances. It is rich in a large number of beneficial substances and is the main nutrient for green food production.

[0003] Organic fertilizer needs to be screened when it is produced and processed into particles. A screening machine is generally used for screening. The screening machines provided in the related art are mostly polarization screens. The polarization screen includes a body, a screen is obliquely installed inside the body, and a polarization motor is arranged at the lower end of the screen;

[0004] When the screening machine is used to screen the processed organic fertilizer, the polarization motor is generally started first, and the polarization motor outputs kinetic energy to the screen, so that the obliquely installed screen produces an up and down polarization movement. When the screen moves, the organic fertilizer to be processed is fed to the surface of the moving screen through the feed inlet, thereby achieving screening; at the same time, sometimes in order to ensure the screening effect of the moving screen on the organic fertilizer, the organic fertilizer is generally first crushed by a crusher and then fed into the screening machine for screening;

[0005] This screening machine has a simple structural design and has a basic organic fertilizer screening function, but it also has some defects, for example; first, the screen is installed obliquely inside the machine body, and the polarization function of the polarization motor on the screen causes the organic fertilizer to fall onto the upper surface of the screen. The acceleration generated by the gravity of the organic fertilizer itself accelerates the residence time of the organic fertilizer on the upper surface of the screen, which results in the average screening effect of the screen on the organic fertilizer; second, the crusher and the screening machine adapted to the screening machine operate separately from each other and are not integrated into an integral device; not only does it increase the kinetic energy of the overall equipment during operation, but it also requires a conveying device to be set up after the crusher crushes the organic fertilizer to transport the crushed organic fertilizer to the inside of the screening machine, which increases the operation steps;

[0032] The screening box 5 is provided with a driving mechanism at the lower end of the arrangement tube 20, and the driving mechanism includes a rotating shaft 21, and the upper end of the rotating shaft 21 passes through the stirring chamber 23 and the screening chamber 24 in sequence, and the end portion is connected to the crushing assembly installed in the crushing chamber 3; the rotating shaft 21 is provided with an elastic member 26 on the portion located in the screening chamber 24;

[0033] In the embodiment of the present invention, when the screening device for processing organic fertilizer is used, after the organic fertilizer to be processed is put into the feed hopper 1, the driving mechanism is started, and the driving mechanism operates to output kinetic energy to drive the rotating shaft 21 to rotate;

[0034] When the rotating shaft 21 rotates, it drives the crushing assembly to operate, so that the organic fertilizer put into the feed hopper 1 is crushed in the crushing chamber 3 and then falls onto the screen 25 installed in the screening chamber 24; when the rotating shaft 21 rotates, it also drives the elastic member 26 to rotate, and the rotating elastic member 26 causes polarization on the upper surface of the screen 25, so that the set screening box 9 realizes reciprocating polarization displacement up and down inside the screening box 5, thereby improving the screening efficiency of the organic fertilizer falling on the upper surface of the screen 25;

[0035] The sieved organic fertilizer falls into the stirring chamber 23. When the rotating shaft 21 rotates, the stirring assembly installed in the stirring chamber 23 also moves to stir and mix the organic fertilizer entering the stirring chamber 23.

[0036] See also Figure 1 In one embodiment of the present invention, the crushing assembly includes a crushing cone 2, and crushing teeth 4 are arranged on the outer side of the crushing cone 2 and the inner wall of the crushing chamber 3. The crushing teeth 4 arranged on the outer side of the crushing cone 2 and the crushing teeth 4 arranged on the inner wall of the crushing chamber 3 are staggered; the middle of the lower end of the crushing cone 2 is connected to the rotating shaft 21;

[0037] In the embodiment of the present invention, when the crushing assembly is used to crush the organic fertilizer put into the feed hopper 1, the rotating shaft 21 will drive the crushing cone 2 to rotate; the crushing teeth 4 installed on the outside of the crushing cone 2 and the crushing teeth 4 installed on the inner wall of the crushing chamber 3 generate an extrusion shear force, so that the organic fertilizer entering the crushing chamber 3 can be crushed;

[0038] The crushed organic fertilizer slides down along the inner wall of the crushing chamber 3 and falls to the upper surface of the screen 25 installed inside the screening box 9 for screening operation;

[0039] See also Figure 1 In one embodiment of the present invention, the left and right sides of the upper end of the screening box 9 pass through the vertical rod 6, the upper end of the vertical rod 6 is fixed on the inner wall of the screening box 5, and the end portion of the lower end of the vertical rod 6 after passing through the inner wall of the screening box 9 is provided with a slide plate 8; at the same time, the vertical rod 6 is provided with a first compression spring 7 on the portion between the inner wall of the screening box 9 and the slide plate 8; in addition, sleeves 10 are symmetrically distributed on both sides of the lower end of the screening box 9, and a sleeve rod 12 passes through the inside of the sleeve 10, and a second compression spring 11 is provided on the portion between the sleeve 10 and the inner wall of the screening box 5;

[0041] When the crushed organic fertilizer falls on the upper surface of the screen 25 and the rotating elastic member 26 causes a vibration force to cooperate with the upper surface of the screen 25, the screening box 9 will slide up and down along the vertical rod 6 and the sleeve rod 12, causing polarization of the screen 25, thereby improving the screening effect of the screen 25 on the organic fertilizer;

[0042] In addition, the elastic member 26 also revolves to grind the upper surface of the screen 25, so as to grind and crush the organic fertilizer that has condensed into blocks, thereby accelerating the penetration of the organic fertilizer into the screen 25;

[0043] See also Figure 1 and Figure 2 In one embodiment of the present invention, the elastic member 26 includes a rolling ball 32, a ball seat 31, a positioning cylinder and a positioning frame, the upper end of the positioning frame is mounted on the rotating shaft 21, and the lower end of the positioning frame is provided with a positioning cylinder; a movable plate 29 is movably installed inside the positioning cylinder; a positioning rod 28 is provided at the middle upper end of the movable plate 29, and a third compression spring 27 is sleeved on the outer side of the positioning rod 28; a connecting rod 30 is provided at the middle lower end of the movable plate 29, and a ball seat 31 is provided at the end portion of the lower end of the connecting rod 30 after passing through the positioning cylinder, and a rolling ball 32 is rotatably installed inside the ball seat 31, and the lower end of the rolling ball 32 contacts the upper surface of the screen 25;

[0044] In an embodiment of the present invention, when the elastic member 26 is used to polarize the upper surface of the screen 25 and grind the agglomerated organic fertilizer, centrifugal force is generated when the rotating shaft 21 rotates, thereby driving the movable plate 29 to move back and forth up and down inside the positioning cylinder, squeezing the third compression spring 27 to deform and produce elastic variables; at the same time, the rolling ball 32 movably installed inside the ball seat 31 can also be caused to cause a polarization force on the set screen 25 while performing a circumferential rolling displacement along the upper surface of the screen 25, so as to improve the screening effect of the screen 25;

[0045] See also Figure 1 In one embodiment of the present invention, the stirring assembly includes a stirring frame 22, and the stirring frame 22 is mounted on the rotating shaft 21. The stirring frame 22 is arranged to have a triangular cross-section, and the outer side of the stirring frame 22 is in contact with the inner wall of the stirring chamber 23;

[0046] In the embodiment of the present invention, when the rotating shaft 21 rotates to drive the stirring frame 22 to rotate, and is used to stir and mix the crushed organic fertilizer entering the stirring chamber 23, the stirring frame 22 with a triangular cross section can enhance its own stirring strength on the one hand, so as to avoid breaking during the stirring of the organic fertilizer, and on the other hand, because the outer side of the stirring frame 22 is in contact with the inner wall of the stirring chamber 23, the fertilizer impurities attached to the inner wall of the stirring chamber 23 can be scraped and cleaned while stirring the fertilizer;

The lower end of the transmission box 18 is fixed to the inner wall of the bottom end of the screening box 5 through a limiting shaft 17.

[0048] In the embodiment of the present invention, when the driving mechanism is used to drive the rotating shaft 21 to rotate, the servo motor 14 is started, and the servo motor 14 outputs kinetic energy to drive the driving wheel 13 to rotate. Since the outer side of the driving wheel 13 and the outer side of the auxiliary driving wheel 16 are connected by the conveyor belt 15, when the driving wheel 13 rotates, the auxiliary driving wheel 16 is driven to rotate at the upper end of the transmission box 18 through the provided conveyor belt 15, and when the auxiliary driving wheel 16 rotates, the rotating shaft 21 installed at the axis position is driven to rotate, so as to realize the output of mechanical kinetic energy; and the provided tripod can enhance the positioning of the rotating shaft 21, which can avoid the misalignment of the rotating shaft 21 during the rotation process, and enhance the overall strength of the output kinetic energy during the rotation process of the auxiliary driving wheel 16.
