Description

Technical Field

[0001] The utility model relates to a screening device and an organic fertilizer screening machine thereof. Background Art

[0002] The production process of organic fertilizer is generally as follows:

[0003] Collection and pre-processing: Collect animal and plant waste materials, crush them and mix them.

[0004] Fermentation: Biological decomposition through composting, anaerobic fermentation and other methods.

[0005] Maturation and sieving: After fermentation is complete, it is sifted and stored for a period of time to improve fertilizer efficiency.

[0006] Among them, the screening of organic fertilizer is to remove impurities, obtain uniform particle size, and ensure product quality.

[0007] The existing screening method generally places the fermented organic fertilizer on a flat gauze with a certain aperture, and then screens the organic fertilizer particles that meet the specifications by vibration.

[0008] However, the above screening method is generally carried out by high-frequency motion of a vibration motor or manual vibration. In actual production, the vibration amplitude of the vibration motor is small, which easily causes the organic fertilizer particles to pile up together and cannot pass through the pores, while the manual vibration method results in high labor costs and low work efficiency. Utility Model Content

[0009] The utility model aims to provide a screening device and an organic fertilizer screening machine thereof. The screening device and the organic fertilizer screening machine thereof can increase the vibration amplitude, reduce the labor cost and improve the work efficiency.

[0010] The above technical objectives of the utility model are achieved through the following technical solutions:

[0011] A screening device comprises: a vibration frame; a gauze screen, both ends of which are bound to the vibration frame in a V shape; a rotating shaft, which is fixedly arranged in the middle of the vibration frame; a connecting plate, which is arranged on one side of the vibration frame; a connecting rod, one end of which is connected to the connecting plate; a swing rod, which is hinged to the connecting rod; a driving member, which is hinged to one end of the swing rod; and a driving motor, which is connected to the driving member.

[0012] The utility model is further configured as follows: the driving motor is a forward and reverse motor, and the forward and reverse angles are between degrees and degrees.

[0013] An organic fertilizer screening machine comprises: a frame; a screening device as described above arranged on the frame; a material collecting bucket arranged on the frame and located below the screening device; and a material collecting device arranged at the bottom of the frame.

[0014] The utility model is further configured as follows: the material receiving device comprises: at least two material receiving barrels arranged in sequence; positioning rods fixedly arranged on both sides of the bottom of the material receiving barrels; a base arranged hollow, and the positioning rods slidably arranged in the base.

[0015] The utility model is further configured to include: a plurality of springs, which are arranged in the middle of the material receiving cylinder, one end of which is fixedly connected to the base, and the other end of which is in contact with the material receiving cylinder.

[0016] The utility model is further configured to include: a switch, which is arranged inside one side of the frame; a pressure plate, which is fixedly arranged on the receiving barrel and corresponds to the position of the switch; and a driving cylinder, which is arranged on one side of the base and is electrically connected to the switch.

[0017] The utility model is further configured that: when the switch is pressed once, the driving cylinder pushes the base to move, thereby switching the position of the material receiving barrel.

[0018] In summary, the utility model has the following beneficial effects:

[0019] 1. Increase the vibration amplitude:

[0020] The design of the drive motor, drive element, swing rod and connecting rod makes the vibration frame swing back and forth like a swing. Compared with the traditional high-frequency small-amplitude vibration, this large-amplitude vibration can better prevent the organic fertilizer particles from piling up and improve the screening effect.

[0021] 2. Reduce labor costs:

[0022] The entire screening process is completed automatically by the machine, without the need for manual vibration, which greatly reduces manpower input.

[0023] 3. Intelligent material collection design:

[0024] The material collecting device adopts a design of rotating use of multiple collecting barrels. When a collecting barrel is full, it triggers a switch through gravity and automatically switches to the next empty barrel. No human intervention is required, ensuring the continuity of the screening work. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0036] like Figure 1 As shown, an organic fertilizer screening machine includes a frame 1.

[0037] Example 1: Screening device 2

[0038] like Figure 2 , Figure 3 , Figure 4 As shown, a screening device 2 for screening organic fertilizer is provided on the frame 1. The screening device 2 includes a vibration frame 3 provided in the middle of the frame 1. A gauze 4 is bound to both ends of the vibration frame 3. The length of the gauze 4 is greater than the length of the vibration frame 3, so that the gauze 4 is V-shaped after the binding is completed. Through holes of different apertures can be provided on the gauze 4 according to actual needs (not shown in the figure).

[0039] The frame 1 is provided with a material collecting bucket 5 below the vibration frame 3. When the organic fertilizer passes through the gauze 4, it will enter the material collecting bucket 5 and be collected.

[0040] A rotating shaft 6 is fixedly provided in the middle of the vibration frame 3. Both ends of the rotating shaft 6 are respectively connected to the bearings between the frame 1. A connecting plate 7 is provided on one side of the vibration frame 3. A connecting rod 8 is provided at one end of the connecting plate 7. A swing rod 9 is hingedly connected to the connecting rod 8. A driving member 10 is hingedly connected to one end of the swing rod 9. The driving member 10 is connected to a driving motor 11.

[0041] The driving motor 11 is a forward and reverse motor, and the forward and reverse angles are between 120 degrees and 180 degrees, and the forward rotation is one time and the reverse rotation is one time. This is the prior art and will not be described in detail.

[0042] As mentioned above, when the driving motor 11 is working, it can drive the driving member 10 to rotate. When the driving member 10 rotates, it drives the swing rod 9 hinged thereto to swing, so that the swing rod 9 drives the connecting rod 8 to swing. The connecting rod 8 drives the connecting plate 7 and one side of the vibration frame 3 to swing, so that the whole presents a state similar to the swing movement, so that the gauze 4 on the vibration frame 3 swings back and forth, and when the corresponding organic fertilizer is placed on the vibration frame 3, the organic fertilizer vibrates with a large amplitude therein, so that the screening effect is better.

[0043] Embodiment 2: Material receiving device 12

[0044] like Figure 5 , Figure 6 As shown, a receiving device 12 for collecting organic fertilizer is provided on the frame 1. The receiving device 12 includes two receiving barrels 13 arranged in sequence at the bottom of the frame 1. Positioning rods 14 are fixedly provided on both sides of the bottom of the receiving barrel 13. The positioning rod 14 is slidably provided with a base 15. The base 15 is hollow, so that the positioning rod 14 can slide up and down in the sliding hole on the base 15 corresponding to the positioning rod 14.

[0045] Optimally, a plurality of springs 16 are provided in the middle of the receiving barrel 13. One end of the spring 16 is fixedly connected to the base 15, and the other end is in contact with the receiving barrel 13. During installation, the positioning rod 14 of the corresponding receiving barrel 13 is inserted into the corresponding sliding hole, and the middle of the bottom of the receiving barrel 13 is in contact with each spring 16. The spring 16 is initially compressed under the weight of the receiving barrel 13 and accumulates elastic potential energy.

[0046] Correspondingly, a switch 17 is provided on one side of the frame 1. The switch 17 is on the inner side of the frame 1. Corresponding to the position where the switch 17 is provided, a pressing plate 18 is fixedly provided on the receiving barrel 13. The pressing plate 18 is provided at the position corresponding to the switch 17. A driving cylinder 19 is provided on one side of the base 15. The driving cylinder 19 and the switch 17 can be connected by wires or by remote control. Pressing the switch 17 once causes the driving cylinder 19 to work once. This is a prior art and will not be described in detail. When the screened organic fertilizer gradually enters the receiving barrel 13, the overall weight of the receiving barrel 13 is gradually increased, so that the positioning rod 14 gradually moves downward, and cooperates with the pressing plate 18 to move downward, and when the weight reaches the position where the pressing plate 18 reaches the switch 17 and abuts against the switch 17, the switch 17 is started. The switch 17 controls the driving cylinder 19 to work, so that the driving cylinder 19 drives the base 15 to slide, so that the collecting barrel 13 loaded with organic fertilizer leaves the bottom of the frame 1, and the empty collecting barrel 13 enters the bottom of the frame 1. At this time, the pressing plate 18 on the empty collecting barrel 13 does not contact the switch 17, thereby achieving the purpose of switching the collecting barrel 13.

[0047] As mentioned above, a plurality of collecting barrels 13 may be provided so that multiple collections can be performed.

[0048] As mentioned above, a corresponding driving cylinder 19 can be provided to push the base 15 to move rightward as shown in the figure when the switch 17 is pressed once, and to move the base 15 to move leftward when the switch 17 is pressed once. The staff can take out the collecting barrel 13 filled with organic fertilizer and put in a new collecting barrel 13, and when the switch 17 is pressed for the second time, the newly placed collecting barrel 13 is returned to the middle of the frame 1 for collecting.

[0049] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
