Description

Technical Field

[0001] The utility model relates to a fertilizer extrusion device, belonging to the field of fertilizer production. Background Art

[0002] A fertilizer stick is a kind of fertilizer required for the growth and development of crops processed into a stick shape, and powdered fertilizer raw materials are added into an extrusion chamber, wherein a spiral rod driven by a motor is installed in rotation in the extrusion chamber, and the motor drives the spiral rod to rotate in the extrusion chamber, and then the powdered fertilizer raw materials enter the extrusion chamber, and are pushed by the spiral rod to be discharged through the discharge hole on the end cover, so that the powdered fertilizer raw materials form a fertilizer stick. When the motor stops unexpectedly, there will be more fertilizer raw materials in the extrusion chamber. When the motor is driven again, the resistance to the rotation of the spiral rod is large due to the influence of the fertilizer raw materials in the extrusion chamber, causing the motor to be in a large load state when starting, which can easily cause the motor to be damaged due to the large load. Therefore, it is necessary to design a fertilizer extrusion device that is convenient for discharging the fertilizer raw materials in the extrusion chamber. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a fertilizer extrusion device to solve the problems raised in the above-mentioned background technology. The utility model divides the extrusion chamber into two parts, and the fertilizer raw materials in the extrusion chamber are discharged conveniently by separating the two parts of the extrusion chamber, so that the motor is in a low-load state when starting.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a fertilizer extrusion device, including a fixed sleeve, the cross-section of the fixed sleeve is semicircular, a movable sleeve with a semicircular cross-section is provided on one side of the fixed sleeve, the movable sleeve and the fixed sleeve together form a cylindrical extrusion chamber, a spiral rod for extruding fertilizer raw materials is provided between the movable sleeve and the fixed sleeve, an end ring rotatably connected to the spiral rod is provided on the spiral rod, the end ring is connected and fixed to the movable sleeve and the fixed sleeve by screws, an end cover is provided on the side of the fixed sleeve away from the end ring, the end cover is connected and fixed to the fixed sleeve and the movable sleeve by screws, a plurality of discharge holes are evenly opened on one side of the end cover, a horizontally arranged hydraulic cylinder is connected and fixed to the outer surface of the fixed sleeve, and the movable end of the hydraulic cylinder is connected and fixed to the movable sleeve.

[0005] Furthermore, the fixed pipe sleeve is connected and fixed to a side away from the movable pipe sleeve with two positioning plates, the movable pipe sleeve is connected and fixed to a side away from the fixed pipe sleeve with two connecting plates matching with the positioning plates, the positioning plate is connected and fixed to a side away from the fixed pipe sleeve with two hydraulic cylinders arranged up and down, the movable end of the hydraulic cylinder is connected and fixed with a connecting rod, and the end of the connecting rod away from the hydraulic cylinder is connected and fixed to the connecting plate.

[0006] Furthermore, a collecting groove is provided directly below the cylindrical extrusion chamber formed by the fixed pipe sleeve and the movable pipe sleeve, the lower end of the positioning plate is connected and fixed to the collecting groove, and the upper end of the collecting groove and a side of the collecting groove away from the positioning plate are both open.

[0007] Furthermore, a protective plate is provided at the bottom of the collecting trough, and a plurality of pin holes penetrating the protective plate are evenly opened on the upper surface of the protective plate. A plurality of pin heads matching the pin holes are evenly fixed at the bottom of the collecting trough, and the pin heads are inserted in the pin holes, and the height of the pin heads is the same as the depth of the pin holes.

[0008] Furthermore, a bottom plate is connected and fixed to the lower portion of one side surface of the collecting tank, and two fixing holes for inserting bolts are provided on the upper surface of the bottom plate.

[0009] Furthermore, one end of the spiral rod away from the end cover is connected and fixed with a connecting disk, and the connecting disk is connected and fixed to the motor output shaft through a plurality of bolts.

[0010] Furthermore, a first semicircular opening matching with the silo discharge port is provided on the upper portion of the outer surface of one end of the fixed sleeve close to the end ring, and a second semicircular opening matching with the silo discharge port is provided on the upper portion of the outer surface of one end of the movable sleeve close to the end ring.

[0011] Beneficial effects of the utility model:

[0012] 1. After the hydraulic cylinder is controlled to shrink, the fixed sleeve and the movable sleeve form a cylindrical extrusion chamber. When the motor stops unexpectedly and there are more fertilizer raw materials remaining in the extrusion chamber, first remove the end ring and the end cover, and then control the hydraulic cylinder to extend. At this time, the distance between the movable sleeve and the fixed sleeve increases, so that the fertilizer raw materials in the fixed sleeve and the movable sleeve fall, thereby reducing the fertilizer raw materials in the extrusion chamber formed by the fixed sleeve and the movable sleeve, so that the extrusion chamber is divided into two. By separating the two parts of the extrusion chamber, it is convenient to discharge the fertilizer raw materials in the extrusion chamber, so that the motor is in a low-load state when starting, which plays a role in protecting the motor.

[0013] 2. When the fixed pipe sleeve is separated from the movable pipe sleeve, the fertilizer raw materials in the extrusion chamber fall into the collecting trough, so that the fallen fertilizer raw materials can be collected centrally to prevent the fallen fertilizer raw materials from being scattered randomly in the working environment. Because one side of the collecting trough is open, it is convenient to transfer the fertilizer raw materials in the collecting trough through the open side of the collecting trough.

[0014] 3. The multiple pin heads at the bottom of the collecting tank are respectively inserted into the multiple pin holes on the guard plate to achieve the connection between the guard plate and the collecting tank. When the fertilizer raw materials in the collecting tank are removed by a shovel, the guard plate plays a role in protecting the bottom of the collecting tank. When the guard plate is damaged, it can be replaced without replacing the collecting tank. BRIEF DESCRIPTION OF THE DRAWINGS
