Description

Technical Field

[0001] The utility model relates to the technical field of organic fertilizer production, in particular to an organic fertilizer raw material pretreatment device. Background Art

[0002] Organic fertilizer is also called "farmyard manure". All organic substances (compounds containing carbon) used as fertilizers are called organic fertilizers. They include human feces, manure, compost, green manure, cake fertilizer, biogas fertilizer, etc. They have the characteristics of many types, wide sources, and long fertilizer effects. Most of the nutrients contained in organic fertilizers are in organic form, which is difficult for crops to use directly. Through the action of microorganisms, a variety of nutrients are slowly released, and nutrients are continuously supplied to crops. The application of organic fertilizers can improve soil structure, coordinate water, fertilizer, gas, and heat in the soil, and improve soil fertility and land productivity.

[0003] In order to ensure the quality of organic fertilizer, it is necessary to use pretreatment equipment for fertilizer production to collect and pretreat organic waste. The pretreatment process includes removing impurities and unusable substances that are too large or too small to prepare for subsequent processing.

[0004] The existing patent document with announcement number CN220678540U discloses a pretreatment equipment for fertilizer production. When in use, the organic fertilizer can be screened twice to screen out impurities mixed in the organic fertilizer, and the screened organic fertilizer and slag can be collected separately and stored in two places respectively. The organic fertilizer in the pipeline can be screened out evenly by using a vibration mechanism to avoid the unscreened organic fertilizer sticking to the inner wall of the screening machine to block the screen holes. After screening, the slag screened out on the left and right sides of the screening machine can be bagged and dumped, and the bag containing waste materials can be limited to avoid the slag being accidentally poured out of the bag during manual bagging.

[0005] Although the above-mentioned fertilizer production pretreatment equipment can solve the corresponding technical problems, the clamp on the bag for collecting waste is connected with the bagging frame, so that the bag mouth is open when collecting the slag, causing the dust contained in the slag to escape from the gap between the hose and the bag, thereby causing a certain impact on the surrounding working environment and the health of the workers. Therefore, we propose an organic fertilizer raw material pretreatment device. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] See also Figure 1-5 , this embodiment provides an organic fertilizer raw material pretreatment device, including a base 1, a screening mechanism 2 for screening and removing impurities from the organic fertilizer raw material, a feed hopper 3, a discharge assembly 4 for removing impurities, a support assembly 5 for supporting the bottom end of the discharge assembly 4, a clamping assembly 6 for clamping and fixing a collecting bag, and a positioning assembly 7 for locking the clamping assembly 6, the screening mechanism 2 is arranged on the top of the base 1, the feed hopper 3 is arranged on the top of the screening mechanism 2, the discharge assembly 4 is respectively provided on both sides of the screening mechanism 2, the support assembly 5 is provided at the bottom end of each discharge assembly 4, and the positioning assembly 7 and the clamping assembly 6 are sequentially arranged on the discharge assembly 4 from top to bottom;

[0027] Among them, the clamping component 6 includes support blocks 61 distributed in a ring shape and equidistantly at the bottom end of the surface of the discharge component 4. A clamping plate 62 is rotatably connected to the support block 61 through a rotating shaft. A protrusion 63 is provided on the side of the clamping plate 62 close to the discharge component 4, and an annular groove 64 adapted to the protrusion 63 is provided on the discharge component 4.

[0028] Working principle: by rotating the screw sleeve 71, under the action of the thread, the screw sleeve 71 drives the collar 72 to move upward, so that the collar 72 is separated from the surface of the clamping plate 62, and then the clamping plate 62 is pried open by the through hole 65, so that the clamping plate 62 is turned over and opened, and the clamping plate 62 drives the protrusion 63 away from the annular groove 64, and then the bag mouth of the collecting bag is sleeved on the discharge pipe 43. When the bag mouth exceeds the height of the annular groove 64, the clamping plate 62 is turned over and closed, so that the clamping plate 62 drives the protrusion 631 and the rubber pad 632 to be synchronously stuck to the inner cavity of the annular groove 64, and the bag mouth of the collecting bag can be fixed on the discharge pipe 43. At this time, the screw sleeve 71 is rotated in the opposite direction, so that the screw sleeve 71 drives the collar 72 to be sleeved on the surface of the clamping plate 62, and the fixing operation of the collecting bag can be completed; the raw materials of the organic fertilizer are screened and impurity-removed by the screening mechanism 2, and the valve is opened, so that the impurities in the organic fertilizer can be transported to the inner cavity of the collecting bag by the discharge pipe 41, the hose 42 and the discharge pipe 43 in turn.

[0029] Beneficial effect: By adding a clamping assembly 6 and a positioning assembly 7 to the discharge pipe 43, the bag opening of the collection bag can be fixed on the discharge pipe 43 in a contracted state, so that the bag opening is in full contact with the discharge pipe 43, which greatly reduces the distance between the bag opening and the discharge pipe 43, thereby effectively reducing the amount of dust escaping upward from the gap between the discharge pipe 43 and the bag opening, which is beneficial to ensuring a good working environment around and the health of the staff.

[0030] Example 2

[0031] See also Figure 1-5 The organic fertilizer raw material pretreatment device provided in this embodiment is different from that in Embodiment 1 in that:

[0032] The screening mechanism 2 includes a screening box 21 located above the base 1, a vibration motor 22 is installed at the center of the bottom of the screening box 21, four springs 23 distributed in a rectangular array are fixedly connected between the screening box 21 and the base 1, and the feed hopper 3 is connected to the top of the screening box 21.

[0033] It should be noted that the working principle of the above-mentioned screening mechanism 2 is consistent with the working principle of the screening box in a pretreatment device for fertilizer production disclosed in the existing announcement number CN220678540U, which is the existing technology and will not be repeated in this technical solution.

[0034] The discharge assembly 4 includes a discharge pipe 41 connected to one side of the screening box 21, wherein the top of one discharge pipe 41 is higher than the top of the other discharge pipe 41, a valve is installed on the discharge pipe 41, the bottom end of the discharge pipe 41 is connected to a hose 42, the bottom end of the hose 42 is connected to a feed pipe 43, a support block 61 is fixedly connected to the surface of the feed pipe 43, and an annular groove 64 is provided at the lower part of the surface of the feed pipe 43. With the above design, the impurities screened in the screening box 21 can be discharged through the discharge pipe 41 by opening the valve.

[0035] The support assembly 5 includes a support ring 51 fixedly connected to the upper surface of the feed tube 43, and support rods 52 are fixedly connected to both sides of the outer surface of the support ring 51. Support legs 53 are fixedly connected between the support rods 52 and the base 1, and the support legs 53 are in an inverted V-shaped structure. The above design can support the feed tube 43 through the support assembly 5, so that when the screening mechanism 2 vibrates, the feed tube 43 will not vibrate accordingly, thereby ensuring the stability of the subsequent connection between the collection bag and the feed tube 43.

[0036] The protrusion 63 includes a protrusion 631 fixedly connected to the inner wall of the clamping plate 62, and a rubber pad 632 is glued to the surface of the protrusion 631, and the rubber pad 632 is clamped to the inner cavity of the annular groove 64. The above design, through the cooperation between the protrusion 63 and the annular groove 64, can not only increase the contact area and friction between the bag opening of the collection bag and the discharge pipe 43, but also clamp the bag opening to the inner cavity of the annular groove 64, thereby playing a fixing role.

[0037] A through hole 65 is provided on the surface of the clamping plate 62. The above design makes it convenient for the staff to move the clamping plate 62 by using the clamping plate 62.

[0038] The positioning assembly 7 includes a screw sleeve 71 threadedly connected to the surface of the feeding tube 43, and a collar 72 is integrally formed at the bottom end of the screw sleeve 71, and the inner wall surface of the collar 72 contacts the outer surface of the clamping plate 62. The above design, by rotating the positioning assembly 7, makes the collar 72 sleeved on the surface of the clamping plate 62, so as to play a positioning role for the clamping plate 62, effectively preventing the clamping assembly 6 from accidentally flipping open under external force when fixing the collection bag, thereby further improving the stability of the clamping assembly 6 in fixing the bag opening.

[0039] The central axes of the feed pipe 43, the support ring 51, the clamping plate 62, the annular groove 64, the screw sleeve 71 and the collar 72 are all on the same straight line.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
