[0002] Compound fertilizers have advantages such as high nutrient content, few by-products, and good physical properties, which can improve fertilizer utilization and play a vital role in promoting high and stable crop yields. During the production of compound fertilizers, it is necessary to perform sample separation and moisture testing. A utility model patent with authorization announcement number CN218003042U discloses a compound fertilizer sample separation and testing device. Although this device can separate and test compound fertilizer samples, its structure is complex, its function is relatively limited, and it cannot perform moisture testing on the samples.

This device can efficiently and uniformly sample compound fertilizers, and after sampling, it can also heat the compound fertilizers to detect moisture content. Furthermore, it can effectively collect harmful gases such as ammonia generated during the moisture detection heating process, thus effectively preventing environmental pollution.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A compound fertilizer sampling and testing device includes a testing frame, a mixing hopper mounted above the testing frame, a feeding hopper mounted at the feeding inlet above the mixing hopper, and a distributing hopper connected below the mixing hopper; a mixing assembly is installed inside the mixing hopper; multiple distributing ports are opened at equal height on the middle side wall of the distributing hopper, and the distributing ports are connected downwards to corresponding sealing heating mechanisms through connecting pipes; the sealing heating mechanisms are equipped with sampling and testing cylinders connected to the connecting pipes; distributing blocks are movably installed vertically in the distributing hopper, and the distributing blocks cooperate with the inner wall of the distributing hopper and are connected to a lifting drive assembly in the distributing hopper; a waste gas collection port is opened at the bottom of the distributing hopper, and the waste gas collection port is connected to a purifier through a suction fan.

[0006] Preferably, a cone-shaped uniform material block with its tip pointing upwards is fixed in the mixing hopper below the feed inlet.

[0007] Preferably, the stirring assembly includes a stirring motor installed below the conical uniform material block, and a stirring rod is installed on the vertically downward stirring shaft of the stirring motor.

[0008] Preferably, the top of the material distribution block is a cone-shaped design with the tip pointing upwards.

[0009] Preferably, the lifting drive assembly includes a movable rod, a swing arm, and a telescopic cylinder. A through hole is provided in the middle of the bottom of the distribution bin. The upper end of the movable rod is fixed to the distribution block, and the lower end extends vertically through the through hole outward. A limiting block is fixed in the middle of the movable rod outside the distribution bin. A spring is sleeved on the movable rod, and the two ends of the spring abut against the limiting block and the bottom of the distribution bin, respectively. The middle of the swing arm is rotatably connected to the detection frame. A sliding groove is provided at one end of the swing arm along its length.

[0011] Preferably, a weight detector is provided at the bottom of the placement slot, and the sample detection cylinder is placed on the weight detector.

[0012] Preferably, the outer periphery of the material distribution block is provided with a first sealing ring that mates with the inner wall of the material distribution bin.

[0013] Preferably, a second sealing ring that mates with the movable rod is fixed at the perforation.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model features a material distribution hopper with vertically movable material distribution blocks. The top of the material distribution blocks is a cone-shaped design with the tip pointing upwards, allowing materials to be evenly dispersed along the cone's apex and discharged outwards through the distribution port. The material distribution blocks are fitted to the inner wall of the material distribution hopper and connected to a lifting drive assembly within the hopper. The lifting drive assembly drives the material distribution blocks to move up and down. When the material distribution blocks move above the distribution port, the material in the hopper cannot be discharged from the port and is in a non-discharging state. At this time, fumes generated during the drying of materials in the sealed chamber can enter the material distribution hopper below the material distribution blocks through the connecting pipe and the distribution port. A waste gas collection port is located at the bottom of the material distribution hopper, connected to a purifier via a suction fan. The fumes entering below the material distribution blocks are drawn into the purifier by the suction fan for the collection and purification of gases such as ammonia, preventing environmental pollution.

[0016] 2. When the material distribution block descends below the material distribution port, the material in the material distribution hopper can be discharged outward through the material distribution port, entering the material distribution and discharging state. The material discharged from the material distribution port is sent to the sealed box through the connecting pipe, and then falls into the sample testing cylinder. The weight detector placed in the trough can monitor the material in the sample testing cylinder in real time. The material in the sample testing cylinder is heated and dried by an electric heater. The weight detector can effectively monitor the weight change of the compound fertilizer before and after drying, thereby calculating and detecting the moisture content in the compound fertilizer.

[0017] 3. When the telescopic cylinder extends, the swing arm rotates around the central hinge point. Utilizing the lever principle, the push rod in the sliding groove moves upward, causing the movable rod to lift the material distribution block upward and compress the spring, thus raising the material distribution baffle. When the telescopic rod retracts, through the cooperation of the swing arm and the movable rod, and with the spring force assisting in the reset, the material distribution baffle moves downward, realizing the material distribution and unloading operation.

[0019] Figure 2 for Figure 1 Enlarged view of point A in the middle. Detailed Implementation

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of application of this utility model.

[0021] like Figure 1-2 As shown, this utility model proposes a compound fertilizer sampling and testing device, including a testing frame 1, a mixing hopper 12 mounted on top of the testing frame 1, a feeding hopper 11 mounted at the feeding inlet above the mixing hopper 12, and a distribution bin 13 connected below the mixing hopper 12. Compound fertilizer material enters the mixing hopper 12 from the feeding hopper 11. A mixing assembly is installed inside the mixing hopper 12. A cone-shaped uniform material block 121 with its tip pointing upwards is fixed in the mixing hopper 12 below the feeding inlet, and the cone-shaped uniform material block 121 is fixed on the front and rear inner walls of the mixing hopper 12. After the material enters the mixing hopper 12, it will be evenly distributed to both sides by the cone-shaped uniform material block 121, thus making it easier for the mixing assembly below to mix more evenly.

[0022] The mixing assembly includes a mixing motor 21 installed below the conical uniform material block 121, and multiple mixing rods 22 horizontally mounted on the vertically downward mixing shaft of the mixing motor 21. The mixing rods 22 rotate under the drive of the mixing motor 21, which can uniformly mix the compound fertilizer in the mixing hopper 12, and the mixing of the mixing rods 22 can break up the large clumps of material in the compound fertilizer, making the sample distribution more uniform.

[0023] Multiple dispensing ports 132 are provided at equal height on the middle side wall of the dispensing bin 13. The dispensing ports 132 are spaced evenly apart. Each dispensing port 132 is connected downwards at an angle to a corresponding sealing heating mechanism 3 via a connecting pipe 14. The sealing heating mechanism 3 contains a sample detection cylinder 5 connected to the connecting pipe 14. The sealing heating mechanism 3 includes a sealing box 31, a placement groove 33, and an electric heater 32. The sealing box 31 has a sealed door 311, through which the sample detection cylinder 5 can be removed and placed. The connecting pipe 14 connects to the top center of the sealing box 31. The placement groove 33, located at the bottom of the sealing box 31, corresponds to the connecting pipe 14. A weight detector 34 is located at the bottom of the placement groove 33, and the sample detection cylinder 5 is placed on the weight detector 34. The electric heater 32 is installed on the side wall of the sealing box 31.

[0024] The material distribution bin 13 is equipped with a vertically movable material distribution baffle 131. The top of the material distribution baffle 131 is a cone-shaped design with the tip pointing upwards, allowing the material to be evenly dispersed along the cone's apex and then discharged outwards through the material distribution port 132. The material distribution baffle 131 is fitted into the inner wall of the material distribution bin 13 and connected to a lifting drive assembly within the material distribution bin 13. The lifting drive assembly can move the material distribution baffle 131 up and down. When the material distribution baffle 131 moves above the material distribution port 132, the material in the material distribution bin 13 cannot be discharged from the material distribution port 132 and is in a non-discharging state. At this time, the fumes generated by the drying of the material in the sealed box 31 can enter the material distribution bin 13 below the material distribution baffle 131 through the connecting pipe 14 and the material distribution port 132. The bottom of the material distribution bin 13 has an exhaust gas collection port 133, which is connected to the purifier 7 via a suction fan 6. The flue gas entering below the distribution baffle 131 is drawn into the purifier 7 by the suction fan 6 for the collection and purification of gases such as ammonia, thus preventing environmental pollution. In addition, a one-way air inlet valve is installed on the sealed box 31 to balance the air pressure inside.

[0025] When the material distribution block 131 descends below the material distribution port 132, the material in the material distribution bin 13 can be discharged outward through the material distribution port 132, and is in the material distribution and discharging state. The material discharged from the material distribution port 132 is sent to the sealed box 31 through the connecting pipe 14, and then falls into the sample detection cylinder 5. The weight detector 34 in the placement groove 33 can monitor the material in the sample detection cylinder 5 in real time. The material in the sample detection cylinder 5 is heated and dried by the electric heater 32. The weight detector 34 can effectively monitor the weight change of the compound fertilizer before and after drying, thereby calculating and detecting the moisture content in the compound fertilizer.

[0026] The outer periphery of the material distribution block 131 is provided with a first sealing ring that mates with the inner wall of the material distribution bin 13. The first sealing ring can effectively improve the sealing performance between the material distribution block 131 and the inner wall of the material distribution bin 13.

[0027] The lifting drive assembly includes a movable rod 41, a swing arm 43, and a telescopic cylinder 44. A through hole is provided in the middle of the bottom of the material distribution bin 13. The upper end of the movable rod 41 is fixed to the material distribution block 131, and the lower end extends outward vertically through the through hole. A second sealing ring that cooperates with the movable rod 41 is fixed at the through hole, which can improve the sliding sealing between the movable rod 41 and the material distribution bin 13. A limiting block 411 is fixed in the middle of the movable rod 41 outside the material distribution bin 13. A spring 42 is sleeved on the movable rod 41, and the two ends of the spring 42 abut against the limiting block 411 and the bottom of the material distribution bin 13, respectively. The middle of the swing arm 43 is rotatably connected to the detection frame 1. A sliding groove 431 is opened at one end of the swing arm 43 along its length direction. The top rod 412, which is vertically fixed at the lower end of the movable rod 41, is slidably locked in the sliding groove 431. The other end of the swing arm 43 is rotatably connected to the piston rod of the telescopic cylinder 44. The tail of the telescopic cylinder 44 is rotatably connected to the material distribution bin 13.

[0028] The telescopic cylinder 44 adopts a hydraulic cylinder structure. When the telescopic cylinder 44 extends, the swing arm 43 rotates around the central hinge point. Utilizing the lever principle, the push rod 412 in the sliding groove 431 moves upward, causing the movable rod 41 to push the material distribution block 131 upward and compress the spring 42, thus realizing the upward movement of the material distribution baffle. When the telescopic rod retracts, through the cooperation of the swing arm 43 and the movable rod 41, and with the elastic force of the spring 42 assisting in the reset, the material distribution baffle moves downward, realizing the material distribution and unloading operation.

[0029] When using this utility model, the compound fertilizer material is stirred in the mixing bucket 12 and then enters the distribution bin 13. When the lifting drive component drives the distribution baffle to descend below the distribution port 132, the material is evenly distributed to the surrounding sealed heating mechanism 3 through the distribution port 132. After the distribution is completed, the lifting drive component drives the distribution baffle to move above the distribution port 132. With the cooperation of the weight detection meter 34 and the electric heater 32 in the sealed heating mechanism 3, the material in the sample detection cylinder 5 is heated and dried and its weight is monitored in real time, thereby completing the moisture detection. The harmful gases generated during the heating are sequentially collected and purified by the suction fan 6 through the connecting pipe 14, the distribution port 132, the distribution bin 13 below the distribution baffle 131, the exhaust gas collection port 133, and the suction fan 6 into the purifier 7 for centralized collection and purification.
