It should be noted that in an embodiment of the present invention, when the screen is damaged, the weight in the transfer box increases rapidly, causing the unfolding ring to move and pull the folding screen to unfold and cover the screen, which can not only achieve temporary screening, but also effectively avoid a large amount of unscreened raw materials from being mixed into the screened raw materials, causing the need for rework; in addition, when the two push-pull frames move, they separate from the support plate. At this time, under the contraction force of the two separation springs, the support plate is pulled downward, and the downward movement of the support plate drives the motor downward, causing the two driving gears to be urgently disengaged, avoiding continuous rotation and the problem of a large amount of unscreened raw materials leaking.

Description

Technical Field

[0001] The invention relates to the technical field of screening devices, and in particular to an impurity screening device used in the production of organic soil conditioners. Background Art

[0002] Organic soil conditioners primarily include organic fertilizers, organic waste, and bio-organic fertilizers. These materials, such as animal manure and plant residues, are produced through fermentation and composting processes. Municipal solid waste and agricultural waste, after processing, can be used to improve soil. Because organic soil conditioners are fermented by microorganisms and contain beneficial microorganisms and organic matter, they can promote soil microbial activity and enhance soil fertility. Organic soil conditioners are widely used in various soil improvement applications, particularly in acidic or infertile soils. They can increase crop yield and quality, improve the soil environment, promote plant root development, enhance crop resistance, and reduce the need for chemical fertilizers. Furthermore, organic soil conditioners slowly release nutrients, reducing the need for chemical fertilizers, lowering agricultural costs, and protecting the ecological environment.

[0003] It should be noted that in the production process of organic soil conditioners, a drum screening machine is needed to screen the raw materials of the organic soil conditioners to ensure the production quality of the organic soil conditioners. However, in the actual production process, since the organic soil conditioners contain a large amount of organic matter, these organic matters are very easy to corrode the screen when screening on the screen, causing the screen to rust and break. As the drum continues to rotate, the unscreened raw materials are continuously thrown out, which will not only increase the damage to the screen, but also cause a large amount of unscreened raw materials to leak directly and mix in the already screened raw materials, causing a large amount of raw materials to need to be reworked.

[0027] In the present invention, through the setting of the automatic discharging device, when the raw materials are screened, the transfer box is driven to rotate by the flip shaft so that the raw materials are flipped and dropped, thereby realizing the function of automatic discharging.

At this time, the weight in the transfer box increases rapidly, which in turn drives the two pull-back rods to move downward, so that the locking frame drives the locking block to disengage from the transverse slide, and then the transverse slide drives multiple transverse slide shafts to move, so that the driving column drives the drive shaft to rotate. At this time, the expansion ring moves to pull the folding screen to expand and cover the screen, which can achieve temporary screening and effectively avoid a large amount of unscreened raw materials from mixing into the screened raw materials, causing the need for rework.

[0029] Furthermore, in the present invention, through the setting of the emergency disconnect device, when the two push-pull frames move, they separate from the support plate. At this time, under the contraction force of the two separation springs, the support plate is pulled downward, and the downward movement of the support plate drives the motor to move downward, so that the two drive gears are urgently disengaged, avoiding continuous rotation and causing a large amount of unscreened raw materials to leak.

A folding screen 803 is connected between the mounting ring 801 and the expansion ring 802. The expansion ring 802 drives the folding screen 803 to cover the screen 3. It should be noted that in the embodiment of the present invention, if the screen is damaged, the rotation of the drum 2 and the impact of the raw materials will cause the damage to be aggravated. At this time, a large amount of unscreened raw materials will be quickly thrown out. At this time, the expansion ring 802 pulls the folding screen 803 to expand and cover the screen 3, thereby achieving temporary screening and effectively preventing a large amount of unscreened raw materials from mixing into the screened raw materials, causing rework.

[0051] Furthermore, in the embodiment of the present invention, an emergency disconnect device 9 is also included. The emergency disconnect device 9 is installed on the screening frame 1. The emergency disconnect device 9 is used to separate the motor 4 from the transmission shaft 5. Specifically, the emergency disconnect device 9 includes a motor bracket 901. The motor bracket 901 is installed on one side of the screening frame 1. A support plate 902 is movably installed on the motor bracket 901. The motor 4 is installed on the support plate 902. The support plate 902 moves downward to drive the motor 4 to separate from the transmission shaft 5. It should be noted that in the embodiment of the present invention, when the screen 3 is damaged, the support plate 902 moves downward and disengages from the motor 4, avoiding continuous rotation and the problem of leakage of a large amount of unscreened raw materials.

[0052] Please refer to the instruction manual Figure 2-Figure 4 Furthermore, in an embodiment of the present invention, an impurity screening device for producing an organic soil conditioner is provided, wherein the automatic discharging device 7 further includes two flip shafts 704, which are respectively mounted on both sides of the transfer box 701, and the two flip shafts 704 are respectively rotatably mounted in the two pull-back rods 703;

[0053] In addition, a flip push plate 705 is sleeved on a flip shaft 704, a rotating push frame 707 is installed at the end of the transmission shaft 5, and a T-shaped push frame 706 is slidably installed on one side of the screening frame 1. The rotating push frame 707 rotates and squeezes the T-shaped push frame 706 to move, which is used to push the flip push plate 705 to rotate. It should be noted that in the embodiment of the present invention, the transmission shaft 5 rotates, driving the rotating push frame 707 to rotate, and the rotating push frame 707 rotates and pushes the T-shaped push frame 706 to move, so that the T-shaped push frame 706 pushes the flip push plate 705 to rotate, and the flip push plate 705 drives the flip shaft 704 to rotate on the pull-back rod 703, and drives the reset torsion spring 710 to be stressed. At the same time, the flip shaft 704 drives the transfer box 701 to rotate so that the raw materials are flipped and fall, completing the discharge.

[0054] More specifically, in the embodiment of the present invention, a mounting slot 709 is defined on the pull-back rod 703, and the tilt shaft 704 is mounted within the mounting slot 709. A return torsion spring 710 is mounted on the inner wall of the mounting slot 709, and the other end of the return torsion spring 710 is mounted on the tilt shaft 704. It should be noted that in the embodiment of the present invention, when the tilt push plate 705 rotates, the transfer box 701 is driven to rotate via the tilt shaft 704. Simultaneously, the tilt shaft 704 rotates within the mounting slot 709, applying force to the return torsion spring 710. Therefore, the return torsion spring 710 can cause the transfer box 701 to return to its original position via the tilt shaft 704.

[0055] Please continue to refer to the instructions attached Figure 2-Figure 4 More specifically, in this embodiment of the present invention, a return spring 708 is mounted on the top side of the return rod 703, and the top end of the return spring 708 is mounted on the inner wall of the mounting bracket 702.

[0056] For further information, please refer to the attached manual. Figure 2 and Figure 5-Figure 9 In an embodiment of the present invention, an impurity screening device for producing an organic soil conditioner is provided. The leakage compensation device 8 further includes a plurality of drive shafts 804 rotatably mounted on a plurality of mounting rings 801 , and a plurality of expansion rings 802 movably mounted on the plurality of drive shafts 804 .

[0057] In addition, a driving groove 805 is formed in an arc shape on the driving shaft 804, and a driving block 806 is installed on the inner wall of the unfolding ring 802, and the driving block 806 extends into the driving groove 805. It should be noted that in the embodiment of the present invention, when the driving column 810 rotates, the driving column 810 rotates to drive the driving shaft 804, and the driving shaft 804 rotates to drive the driving block 806 to move through the driving groove 805, thereby causing the driving block 806 to drive the unfolding ring 802 to move, thereby achieving the purpose of driving the folding screen 803 to unfold through the unfolding ring 802.

[0058] More specifically, in the embodiment of the present invention, a driving column 810 is mounted on one end of the drive shaft 804, and the driving column 810 is rotatably mounted on an adjacent mounting ring 801. The mounting ring 801 defines a mounting cavity 807, within which a transverse sliding shaft 809 is disposed. The driving column 810 defines a driving groove 811, and one end of the transverse sliding shaft 809 extends into the driving groove 811.

It should be noted that in the embodiment of the present invention, when the gravity in the transfer box 701 unexpectedly increases, the two pull-back rods 703 are driven to move, so that the pull-back rods 703 drive the locking block 813 to disengage from the transverse slide 808 through the locking frame 812, thereby achieving the purpose of automatic unlocking.

[0060] For further information, please refer to the attached manual. Figure 10-11 In an embodiment of the present invention, an impurity screening device for producing organic soil conditioners is provided. A motor bracket 901 is provided with lifting slots 903 on both sides, and a support plate 902 is movably mounted within the two lifting slots 903. Furthermore, a separation spring 904 is mounted on the bottom inner wall of the lifting slots 903, and the top end of the separation spring 904 is mounted on the bottom side of the support plate 902. It should be noted that in this embodiment of the present invention, after the support plate 902 is unlocked, the pullback force of the two separation springs 904 pulls the support plate 902 downward, thereby separating the motor 4 from the transmission shaft 5.

[0061] More specifically, in the embodiment of the present invention, the motor bracket 901 is provided with two push-pull slots 905, in which push-pull racks 906 are movably mounted, and the push-pull racks 906 are mounted on the transverse slide 808. In addition, the support plate 902 is provided with two insertion slots 907, and the two push-pull racks 906 are respectively inserted into the two insertion slots 907. It should be noted that in the embodiment of the present invention, when the transverse slide 808 moves, the two push-pull racks 906 are driven to move along the two push-pull slots 905, causing the push-pull racks 906 to disengage from the insertion slots 907, thereby unlocking the support plate 902.

[0062] Please continue to refer to the instructions attached Figure 10-11 More specifically, a retraction spring 908 is mounted on the inner wall of the push-pull chute 905, and the other end of the retraction spring 908 is mounted on the push-pull frame 906. It should be noted that in this embodiment of the present invention, after the transverse slide 808 is unlocked, the pull force of the separation spring 904 drives the push-pull frame 906 to reset, allowing the push-pull frame 906 to automatically detach from the support plate 902.

[0063] In summary, the working principle of the impurity screening device for producing organic soil conditioner provided by the embodiment of the present invention is:

[0064] When the raw materials are screened, the motor 4 drives a driving gear 6 to rotate, which in turn drives the transmission shaft 5 to rotate through another driving gear 6. The transmission shaft 5 drives multiple screens 3 to rotate through the drum 2 to screen the raw materials, so that the screened raw materials are output through the screening material outlet tube 10, and the screened raw materials are output through the raw material outlet tube 11. The screened raw materials fall on the transfer box 701, and at the same time the transmission shaft 5 rotates, driving the rotating push frame 707 to rotate, and the rotating push frame 707 rotates to drive the T-shaped push frame 706 to move, so that the T-shaped push frame 706 drives the flip push plate 705 to rotate, and the flip push plate 705 drives the flip shaft 704 to rotate on the pull-back rod 703, and drives the reset torsion spring 710 to be stressed. At the same time, the flip shaft 704 drives the transfer box 701 to rotate so that the raw materials are flipped and fall, completing the discharge;

[0065] It should be noted that if the screen is damaged, the damage is aggravated by the rotation of the drum 2 and the impact of the raw materials. At this time, a large amount of unscreened raw materials are quickly thrown out and enter the transfer box 701 through the screening material outlet cylinder 10. At this time, the weight in the transfer box 701 increases rapidly, thereby driving the two pull-back rods 703 to move downward. When the pull-back rod 703 moves downward, the pull-back spring 708 is stretched and the locking frame 812 is driven to move. The locking frame 812 drives the locking block 813 to disengage from the transverse slide 808. At this time, under the contraction force of the two contraction springs 908, the two push-pull frames 906 are pulled to move, so that the two push-pull frames 906 drive the transverse slide 808 to move. The movement of the transverse slide 808 simultaneously drives multiple transverse slide shafts 809 to move, and the transverse slide shaft 809 moves in the driving groove 811. Then, the driving column 810 is driven to rotate, and the driving column 810 drives the driving shaft 804 to rotate. The driving shaft 804 rotates through the driving groove 805 to drive the driving block 806 to move, so that the driving block 806 drives the unfolding ring 802 to move, and the unfolding ring 802 moves to pull the folding screen 803 to unfold and cover the screen 3, which can not only achieve temporary screening, but also effectively prevent a large amount of unscreened raw materials from mixing into the screened raw materials, causing the need for rework; in addition, when the screen 3 is damaged, the leaked unscreened raw materials can be effectively received by the transfer box 701, and when the transfer box 701 moves down, the flip push plate 705 is separated from the T-shaped push frame 706. At this time, the transfer box 701 no longer flips, which can effectively prevent unscreened raw materials from mixing into the screened raw materials;

[0066] It should be further explained that when the two push-pull frames 906 move, they separate from the support plate 902. At this time, under the contraction force of the two separation springs 904, the support plate 902 is pulled downward, and the downward movement of the support plate 902 drives the motor 4 to move downward, so that the two drive gears 6 are urgently disengaged to avoid continuous rotation, which causes a large amount of unscreened raw materials to leak.

[0067] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
