Description

Technical Field

[0001] The utility model relates to the technical field of blanking auxiliary devices, in particular to a telescopic auxiliary blanking structure and a fertilizer storage tank. Background Art

[0002] Generally, a tank device can be used to store the produced fertilizer, and then it is discharged into a packaging bag through a blanking pipe at the bottom of the tank to achieve packaging. A metering valve is generally provided on the blanking pipe to control the amount of fertilizer discharged so that the weight specification of the package meets the requirements. In the actual production process, the packaging bag is transported to the lower part of the blanking pipe by a conveying device, and then the upper opening is opened. The fertilizer falls into the packaging bag after passing through the blanking pipe to achieve loading. Since there are some smaller particles mixed in the fertilizer, dust will be raised during the process of falling from the blanking pipe into the packaging bag (the smaller particles may become even smaller due to impact and form dust, and at the same time, there are also some powder substances in the fertilizer that will also form dust during the process). If the lower end of the blanking pipe is not located inside the packaging bag, these dusts will leak out and cause dust pollution to the workshop. Therefore, generally, the blanking pipe is set longer so that it can smoothly enter the packaging bag. However, because the blanking pipe cannot move, when the packaging bag needs to be moved away after being filled, the blanking pipe may pull down the packaging bag (the blanking pipe is located inside the packaging bag, and there will be interference between the blanking pipe and the packaging bag when the conveying device moves away the packaging bag), resulting in unnecessary trouble. Content of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the utility model provides a telescopic auxiliary blanking structure, which solves the problem that in the prior art, the blanking pipe needs to be longer to extend into the packaging bag to avoid dust, which will cause unnecessary trouble.

[0004] According to an embodiment of the utility model, a telescopic auxiliary blanking structure is connected to the blanking pipe, and it includes a pair of connecting half-hoops fixedly arranged outside the blanking pipe in a surrounding manner, a connecting cylinder sleeved outside the two connecting half-hoops, a first mounting ring fixedly connected to the connecting cylinder, and a telescopic cylinder fixedly connected to the first mounting ring. One end of the telescopic cylinder is communicated with one end of the blanking pipe through the first mounting ring, and the other end is also fixedly connected with a second mounting ring. A locking stay rope is also connected between the first mounting ring and the second mounting ring.

[0005] In the above embodiments, the materials in the blanking pipe first enter the telescopic cylinder and then enter the packaging bag below. The telescopic cylinder can be telescoped to change its length, so that it can smoothly enter and exit the packaging bag below. Therefore, the blanking pipe in this solution can be set shorter to be located above the packaging bag. Entering the packaging bag through the telescopic cylinder ensures smooth loading, avoids dust leakage, and can smoothly exit the packaging bag to avoid pulling down the packaging bag, solving the problem in the prior art that the blanking pipe needs to be longer to extend into the packaging bag to avoid dust, which will cause unnecessary troubles.

[0006] Further, a locking rod is fixedly connected to the first mounting ring, and a first through hole for the locking pull rope to pass through is provided on the second mounting ring. One end of the locking pull rope passes through the first through hole and is fixedly connected with a limiting block, and the limiting block and the first mounting ring are respectively located on both sides of the second mounting ring.

[0007] Further, a second through hole for the locking pull rope to pass through is provided on the first mounting ring, and the locking rod and the second mounting ring are located on both sides of the first mounting ring.

[0008] Further, a material guiding hopper is fixedly connected to the side of the second mounting ring facing away from the first mounting ring.

[0009] Further, the connecting cylinder is respectively connected to the two connecting half-hoops through screws.

[0010] Further, both of the two connecting half-hoops are arc-shaped, and connecting ear plates are respectively fixedly connected to both ends. The two connecting half-hoops are enclosed into a circle, and the two connecting ear plates at both ends are connected through bolts.

[0011] Further, elastic compression layers are fixedly connected to the inner side walls of the two connecting half-hoops facing each other.

[0012] According to the embodiment, the present invention further provides a fertilizer storage tank, which includes the above telescopic auxiliary blanking structure, and further includes a tank body, and the blanking pipe is fixedly connected to the bottom of the tank body.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By using the telescopic cylinder to assist in blanking and prevent dust leakage, the blanking pipe in this solution can be set shorter to be located above the packaging bag. Entering the packaging bag through the telescopic cylinder ensures smooth loading, and can smoothly exit the packaging bag to avoid pulling down the packaging bag, solving the problem in the prior art that the blanking pipe needs to be longer to extend into the packaging bag to avoid dust, which will cause unnecessary troubles.

Specific embodiments

[0019] The technical solutions in the present utility model will be further described below in conjunction with the drawings and embodiments.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0021] In an exemplary embodiment, as Figure 1 , 2 shown, this embodiment provides a telescopic auxiliary blanking structure, which is connected to the blanking pipe 1. It includes a pair of connecting half hoops 2 fixedly arranged outside the blanking pipe 1 in a surrounding manner, a connecting cylinder 3 sleeved outside the two connecting half hoops 2, a first mounting ring 4 fixedly connected to the connecting cylinder 3, a telescopic cylinder 5 fixedly connected to the first mounting ring 4. One end of the telescopic cylinder 5 is communicated with one end of the blanking pipe 1 through the first mounting ring 4, and the other end is also fixedly connected with a second mounting ring 6. A locking pull rope 7 is also connected between the first mounting ring 4 and the second mounting ring 6. The connecting cylinder 3 is respectively connected to the two connecting half hoops 2 through screw rods 8 (blind screw holes for connecting the screw rods 8 are provided on the connecting half hoops 2, and through screw holes for the screw rods 8 to pass through are provided on the connecting cylinder 3), so that the connecting cylinder 3 can be conveniently disassembled and installed.

[0022] In the above embodiments, the material (i.e., fertilizer) in the blanking pipe 1 first enters the telescopic cylinder 5 and then enters the packaging bag below. The telescopic cylinder 5 can be telescoped to change its length, so that it can smoothly enter and exit the packaging bag below. Therefore, the blanking pipe 1 in this solution can be set shorter to be located above the packaging bag. Entering the packaging bag through the telescopic cylinder 5 ensures smooth loading, avoids dust leakage, and can smoothly exit the packaging bag, avoiding pulling down the packaging bag, solving the problem in the prior art that the blanking pipe 1 needs to be longer to extend into the packaging bag to avoid dust, which may cause unnecessary troubles. Among them, the set telescopic cylinder 5 can adopt a cotton cloth structure, and the overall length can be changed with the assistance of the locking pull rope 7. Specifically: one end of the locking pull rope 7 is connected to the second mounting ring 6, and the other end is lifted upward to make the telescopic cylinder 5 shorter, and the telescopic cylinder 5 becomes longer when it is relaxed downward. After adjustment, the other end of the locking pull rope 7 can be connected to the first mounting ring 4, so that the length of the telescopic cylinder 5 is stable. When discharging materials, pick up the second mounting ring 6 upward, and then smoothly put it into the packaging bag for discharging materials. After completion, lift the second mounting ring 6 upward through the locking pull rope 7 to take out the packaging bag, then move the packaging bag away, and then proceed to the next round. More specifically, a locking rod 9 is also fixedly connected to the first mounting ring 4 for the locking pull rope 7 to be connected (it can be tied to the locking rod 9). In particular, the set locking rod 9 and locking pull rope 7 can be a corresponding pair, or more, preferably evenly surrounding the outside of the telescopic cylinder 5. More specifically, a first through hole for the locking pull rope 7 to pass through is also provided on the second mounting ring 6, and one end of the locking pull rope 7 passes through the first through hole and is fixedly connected with a limiting block 10. The limiting block 10 and the first mounting ring 4 are respectively located on both sides of the second mounting ring 6, and the limiting block 10 cannot pass through the first through hole, so that the second mounting ring 6 can be pulled upward by the other end of the locking pull rope 7. Similarly, a second through hole for the locking pull rope 7 to pass through is provided on the first mounting ring 4, and the locking rod 9 and the second mounting ring 6 are located on both sides of the first mounting ring 4, so that the connection between the locking pull rope 7 and the corresponding locking rod 9 can be realized more smoothly and conveniently.

[0023] As Figure 1 shown, in a further exemplary solution, a material guiding hopper 11 is also fixedly connected to the side of the second mounting ring 6 facing away from the first mounting ring 4. The material enters the material guiding hopper 11 after passing through the telescopic cylinder 5 to realize discharging. In this way, the weight below the telescopic cylinder 5 can be increased, so that the locking pull rope 7 can be in a tensioned state, ensuring smooth discharging.

[0024] As Figure 1 、 2As shown, in a further exemplary solution, both of the two connecting half-hoops 2 are arc-shaped, and connecting ear plates 12 are fixedly connected to both ends respectively. The two connecting half-hoops 2 are enclosed to form a circle, and the two connecting ear plates 12 at both ends are connected by bolts 13, so that the installation of the connecting half-hoops 2 is realized. At the same time, elastic compression layers 14 are fixedly connected to the inner side walls of the two connecting half-hoops 2 facing each other. After the two connecting half-hoops 2 are connected, the elastic compression layers 14 are in a compressed state, so that the connection between the connecting half-hoops 2 and the blanking pipe 1 is more stable, ensuring the stable state of structures such as the telescopic cylinder 5 below. Among them, the elastic compression layers 14 can be made of relatively thick rubber material.

[0025] In another exemplary solution, as Figure 1 shown, a fertilizer storage tank is further provided, which includes the telescopic auxiliary blanking structure in the above embodiment, and further includes a tank body 15, and the blanking pipe 1 is fixedly connected to the bottom of the tank body 15.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
