Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production, in particular to a device for unloading ton bags of blended fertilizer. Background Art

[0002] Blended fertilizers mainly contain any two or three of the three nutrients: nitrogen, phosphorus, and potassium. Due to the flexible formula in the production process, blended fertilizers are particularly suitable for areas with large land areas, complex soil types, and a wide variety of crops. Blended fertilizers can be in powdered or granular form, making it convenient for farmers to mix and use them according to soil and crop needs.

[0003] When producing blended fertilizer, it is necessary to hang the ton bag containing the raw materials, and then open the bottom of the ton bag, so that gravity can be used to make the materials fall into the discharge hopper. In addition, during the discharge process, in order to ensure that the size of the fertilizer particles is relatively consistent, a filtering device will be installed when discharging the materials.

[0004] For example, the mixing fertilizer feeding device disclosed in the authorization announcement number CN212393225U utilizes a screen for filtering and screening. However, the filtering devices are all arranged in a flat surface, and the bottom opening of the ton bag is relatively small relative to the feeding chute. Therefore, most of the materials falling from the ton bag are concentrated on the top of the center of the filtering device and accumulated into a cone. As a result, other positions of the filtering device cannot filter the materials, and can only wait for the materials to slowly pass through the center of the filtering device, affecting the feeding efficiency. Utility Model Content

[0005] The main purpose of the utility model is to provide a device for unloading ton bags of blended fertilizer. The filter plate is arched upward, so after the material comes into contact with the filter plate, it will roll to the four sides of the filter plate under the action of gravity, so that the material can fall through the filter holes at various positions of the filter plate, thereby increasing the utilization area of ​​the filter plate and increasing the unloading speed.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A device for unloading ton bags of blended fertilizer comprises a base, a silo is provided in the base, a crawler conveyor is provided in the silo, a ton bag hanging assembly is provided on the top of the base, a plurality of unloading chutes connected to the silo are provided on the top of the base, a filter plate is provided in the unloading chutes, the filter plate is arched upward and has a plurality of filter holes for material to pass through.

[0008] Furthermore, the feed trough comprises a straight cylindrical trough matching the shape of the filter plate, the straight cylindrical trough has a tapered trough connected to the silo, and the tapered trough has a larger upper opening and a smaller lower opening.

[0009] Furthermore, the filter plate is located at the junction of the straight cylindrical groove and the tapered groove.

[0010] Furthermore, the ton bag hanging assembly includes a hanging rod located above the base, and a plurality of hooks matching the positions of the discharge chute are fixed on the hanging rod.

[0011] Furthermore, a fixing rod is connected to the hanging rod, and the fixing rod is fixedly connected to the base.

[0012] Furthermore, a discharge port connected to the silo is provided on one side of the base, and the material discharge end of the crawler conveyor passes through the discharge port and is located outside the silo.

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

[0014] 1. The filter plate of the utility model is arched upward, so after the material contacts the filter plate, it will roll to the four sides of the filter plate under the action of gravity, so that the material can fall through the filter holes at various positions of the filter plate, thereby increasing the utilization area of ​​the filter plate and increasing the material feeding speed.

[0015] 2. The filter plate of the utility model is located at the intersection of the straight cylindrical groove and the conical groove. The height position of the filter plate is fixed by using the shape of the conical groove which becomes narrower as it goes downwards, while the straight cylindrical groove can position the horizontal position of the filter plate, thereby eliminating the need for an additional fixing mechanism to fix the filter plate, thereby improving the convenience of disassembly and assembly of the filter plate.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-4 As shown, a device for discharging ton bags of blended fertilizer includes a base 1, a silo 4 is provided in the base 1, a crawler conveyor 5 is provided in the silo 4, a ton bag hanging assembly 7 is provided on the top of the base 1, and a plurality of discharging chutes 2 connected with the silo 4 are provided on the top of the base 1, a filter plate 3 is provided in the discharging trough 2, and the filter plate 3 is arched upward and has a plurality of filter holes 301 for the material to pass through.

[0024] In this embodiment, if Figure 1 As shown, the ton bag hanging assembly 7 includes a hanging rod 703 located above the base 1, and a number of hooks 702 are fixed on the hanging rod 703 that match the position of the discharge chute 2. The ton bag containing any element of nitrogen, phosphorus, and potassium is hung on the hook 702, and the ton bag opening is opened, so that the material in the ton bag enters the discharge chute 2. At this time, the filter plate 3 can filter the material and intercept large particles of material, while small particles of material enter the silo 4 through the filter hole 301. In this process, Figure 2 As shown, since the filter plate 3 is arched upward, the material will roll around the filter plate 3 under the action of gravity after contacting the filter plate 3, thereby increasing the utilization area of ​​the filter plate 3 and increasing the material feeding speed.

[0025] Among them, such as Figure 1 and Figure 4 As shown, the discharge chute 2 includes a straight cylindrical trough 201 that matches the shape of the filter plate 3. The straight cylindrical trough 201 has a conical trough 202 that is connected to the silo 4. The conical trough 202 has a large upper opening and a small lower opening. The material in the ton bag first enters the straight cylindrical trough 201, and then falls into the silo 4 through the conical trough 202 after being filtered by the filter plate 3. The filter plate 3 is located at the intersection of the straight cylindrical trough 201 and the conical trough 202. The conical trough 202 is narrowed as it goes downwards to fix its own height position, and the straight cylindrical trough 201 can position the horizontal position of the filter plate 3, so there is no need to use an additional fixing mechanism to fix the filter plate 3, thereby improving the convenience of disassembly and assembly of the filter plate 3.

[0026] The hanging rod 703 is connected to a fixing rod 701 , which is fixedly connected to the base 1 . A plurality of fixing rods 701 are provided to improve the stability of the hanging rod 703 .

[0027] Among them, such as Figure 1As shown, a discharge port 6 connected to the silo 4 is opened on one side of the base 1, and the material discharge end of the crawler conveyor 5 passes through the discharge port 6 and is located outside the silo 4. The wide belt of the crawler conveyor 5 matches the width of the silo 4. When the material falls into the silo 4, the crawler belt of the crawler conveyor 5 will carry the material, thereby transporting the material out of the silo 4 through the discharge port 6, and then the elevator in the production workshop transports the transported material to the mixing equipment, thereby mixing the various raw materials evenly.

[0028] Working principle: first, hang the ton bag on the hook 702, and then open the ton bag, so that the material in the ton bag enters the discharge chute 2. At this time, the filter plate 3 can filter the material and intercept large particles of material, while small particles of material enter the silo 4 through the filter hole 301. Since the filter plate 3 is arched upward, the material will roll to the surrounding areas of the filter plate 3. When the material enters the silo 4, it will fall on the top of the crawler conveyor 5. Therefore, when the crawler conveyor 5 is started, the fallen material can be sent out of the silo 4 through the discharge port 6, and then the material is transported to the mixing equipment under the action of the workshop lifting conveyor to mix the various raw materials evenly.

[0029] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
