Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a quantitative feeding device for fertilizer raw materials. Background Art

[0002] Chemical fertilizers, referred to as fertilizers, are fertilizers made by chemical and / or physical methods that contain one or more nutrients needed for the growth of crops. They are also called inorganic fertilizers, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micro-fertilizers, compound fertilizers, etc., which are not edible. They have the following common characteristics: simple ingredients and high nutrient content; fast fertilizer effect and strong fertilizer effect; some fertilizers have acid-base reactions; generally do not contain organic matter and have no effect on soil improvement and fertilization. There are many types of chemical fertilizers, and their properties and application methods vary greatly. Fertilizer raw materials need to be processed during the processing.

[0003] For example, a Chinese authorized patent with the announcement number CN215233600U is a feeding device for fertilizer production, which includes a conveying mechanism, a stirring mechanism, and a vibration mechanism for screening qualified fertilizers for uniform discharge. The vibration mechanism is arranged on one side of the conveying mechanism, and the stirring mechanism is arranged above the vibration mechanism. The conveying mechanism includes a conveying frame, a conveying shaft, a conveying motor, and a conveyor belt. The conveying shaft is arranged on the inner side above the conveying frame, and the conveying motor is arranged on the front side of the conveying shaft. The utility model adopts a stirring mechanism and a vibration mechanism, and uses a stirring motor to drive the stirring shaft and the paddles to rotate, which can quickly and evenly stir the fertilizer raw materials to prevent the fertilizers from sticking together. The vibration mechanism can achieve high screening efficiency and screen out impurities in the fertilizer. At the same time, the fertilizer discharge speed can be controlled to prevent blockage, thereby improving the qualified rate of fertilizers.

[0004] The above-mentioned traditional feeding device feeds materials by a single vibration method. However, during use, the fertilizer is very sticky, and vibration still cannot completely drive the material to fall. At the same time, the feeding rate of the fertilizer raw materials is not constant enough. The staff needs to wait for a long time when collecting, which affects the feeding efficiency of the equipment. Utility Model Content

[0027] 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.

[0028] Example

[0029] Reference Figure 1-6 As shown, a quantitative feeding device for fertilizer raw materials includes a mixing box shell 1, wherein the top of the mixing box shell 1 is provided with a feed port 214, and the bottom is provided with a feeding barrel 217. The bottom of the mixing box shell 1 is connected to a closing plate 218 through a pushing mechanism, and a second motor 220 is installed at the bottom of the closing plate 218. The output end of the second motor 220 is connected to a dividing hopper 221 located in the middle of the feeding barrel 217. The dividing hopper 221 is truncated, and a sealing layer 219 that fits the feeding barrel 217 is fixed to the outer wall of the bottom end of the dividing hopper 221. This method facilitates the feeding of fertilizer raw materials to the surroundings and can accelerate the falling rate of the materials. A cleaning plate 222 is fixed to the top of the dividing hopper 221. By turning on the second motor 220 to drive the dividing hopper 221 and the cleaning plate 222 to rotate, the fertilizer raw materials at the bottom of the mixing box shell 1 can be stirred to avoid the fertilizer raw materials from sticking.

[0030] The bottom end of the cleaning plate 222 is connected with a scraper 225 through a telescopic mechanism, and the scraper 225 is in contact with the inner wall of the bottom end of the mixing box shell 1, so as to improve the effect of preventing the fertilizer from sticking.

[0031] The telescopic mechanism includes a fixed cylinder 223, a movable cylinder 224 and a spring 226. The fixed cylinder 223 is fixed to the bottom end of the cleaning plate 222. One end of the movable cylinder 224 is inserted into the fixed cylinder 223 and the other end is fixed to the scraper 225. The fixed cylinder 223 and the movable cylinder 224 are connected by a spring 226. When the closing plate 218 moves downward, the material distribution hopper 221 and the cleaning plate 222 are pressed downward. At this time, the fixed cylinder 223 is pressed downward, driving the spring 226 to compress. When the lower cylinder 217 is opened, the scraper 225 can still contact the inner wall of the bottom end of the mixing box shell 1 to achieve the use effect.

[0032] A first motor 213 is installed at the top of the mixing box housing 1, and a rotating rod 215 is connected to the output end of the first motor 213. A plurality of stirring rods 216 are fixed to the outer wall of the rotating rod 215. When the first motor 213 is turned on to drive the rotating rod 215 and the plurality of stirring rods 216 to rotate, the inside of the mixing box housing 1 can be stirred to prevent the fertilizer raw materials from sticking to the inner wall of the mixing box housing 1. A fixing ring 211 is fixed to the outer wall of the mixing box housing 1, and a bracket 212 supported on the ground is fixed to the outer wall of the fixing ring 211 to ensure that the mixing box housing 1 can be stably supported.

[0033] The pushing mechanism includes a sliding block 311, a hinge rod 312, a fixed plate 314, a threaded rod 315 and a handle 316. The sliding block 311 is slidably connected to the bottom end of the mixing box housing 1 and is hinged to the closing plate 218 through the hinge rod 312. The fixing plate 314 is fixed to the bottom end of the mixing box housing 1. The inner wall of the fixing plate 314 is threadedly connected to the threaded rod 315 that is rotatably connected to the sliding block 311. The handle 316 is fixed to the end of the threaded rod 315 away from the sliding block 311. A sliding groove 313 that is slidably matched with the sliding block 311 is provided at the bottom end of the mixing box housing 1. The cross sections of the sliding block 311 and the sliding groove 313 are rectangular. The rotating handle 316 drives the threaded rod 315 to rotate. Under the action of the thread, the sliding block 311 can be pushed to move back and forth laterally inside the hinge rod 312, so that the hinge rod 312 rotates, thereby controlling the lifting and lowering of the closing plate 218. When the closing plate 218 descends, the bottom of the discharge barrel 217 is in an open state, and the fertilizer raw materials can fall under gravity, making it easy for the staff to collect them; when the closing plate 218 rises, the bottom of the discharge barrel 217 is in a closed state, and the fertilizer raw materials can be stirred to avoid sticking, making the discharge faster and more efficient.

[0034] Working principle: When it is needed, the raw materials are added into the feed port 214 and the first motor 213 is turned on to drive the rotating rod 215 and the stirring rod 216 to rotate to achieve the stirring effect. Then, the second motor 220 is turned on to drive the dividing hopper 221, the cleaning plate 222, the telescopic mechanism and the scraper 225 to rotate in a circle to achieve sufficient stirring effect and prevent the fertilizer from sticking to the inner wall of the mixing box shell 1.

[0035] When discharging is required, the threaded rod 315 is rotated by rotating the handle 316, and the sliding block 311 is driven to slide inside the sliding groove 313 under the action of the thread. At this time, the hinged rod 312 rotates and pushes the closing plate 218 to move downward, driving the movable cylinder 224 to embed into the fixed cylinder 223, and the driving spring 226 is compressed. At this time, the fertilizer raw materials can be dispersed through the distribution hopper 221, so that the materials can fall in a concentrated manner. By controlling the falling distance of the closing plate 218, the quantitative discharging effect of the equipment is controlled to ensure that after the closing plate 218 drops, the fertilizer raw materials can fall directly without sticking.

[0036] 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.
