Description

Technical Field

[0001] This application relates to the field of equipment technology for preparing nutrient soil, and in particular to a feed detection device for preparing nutrient soil. Background Technology

[0002] Nutrient soil is a cultivation substrate made by mixing leaf mold, garden soil, river sand, and other raw materials in a certain proportion. It is widely used in the cultivation of flowers, seedlings, vegetables, and other crops. In the industrial production of nutrient soil, the quality of the raw materials directly affects the fertility, aeration, and stability of the final product. Therefore, it is necessary to conduct strict testing on the raw materials. The main testing indicators include moisture content, particle size, and impurity content (such as stones, metal fragments, plastic impurities, etc.). In existing technologies, the testing of nutrient soil feed materials mostly relies on manual inspection or single-parameter testing equipment. Manual inspection is inefficient, labor-intensive, and yields highly subjective results. Single-parameter testing equipment requires multiple, step-by-step tests on the same batch of feed material, which is cumbersome, has a long testing cycle, and cannot achieve automated linkage between testing and screening. This results in substandard raw materials entering subsequent mixing processes, affecting the quality of the nutrient soil product and reducing production efficiency. Utility Model Content

[0003] In view of this, this application provides a feed detection device for preparing nutrient soil, which can simultaneously detect the feed moisture content, particle size and impurity content, automatically separate qualified and unqualified materials, and improve detection efficiency and feed quality.

[0004] This application provides a feed detection device for preparing nutrient soil, the feed detection device for preparing nutrient soil comprising: Supporting framework; The feeding mechanism includes a feeding hopper and a spiral conveying pipe. The spiral conveying pipe is inclinedly fixed to the support frame, and the feeding hopper is fixed to the top of the support frame. The bottom outlet of the feeding hopper is sealed and connected to the inlet end of the spiral conveying pipe. The detection mechanism, located in the middle section of the spiral conveying pipe, includes a moisture detection element, a particle size detection element, and an impurity identification element. The detection probe of the moisture detection element penetrates the pipe wall and extends into the pipe. The particle size detection element includes a laser emitter and a laser receiver symmetrically arranged on both sides of the spiral conveying pipe. The impurity identification element is fixed above the spiral conveying pipe. A screening mechanism is provided at the discharge end of the spiral conveyor pipe, including a main discharge channel, a diversion channel and a non-conforming material collection box. The main discharge channel is connected to the discharge end of the spiral conveyor pipe. The diversion channel is inclined downward and provided on the side wall of the main discharge channel. The non-conforming material collection box is provided below the diversion channel.

[0005] The spiral conveying pipe is equipped with spiral blades inside, which are driven to rotate by a drive motor. The drive motor is fixed to the bottom of the support frame by a motor base.

[0006] The screening mechanism further includes an electromagnetic baffle, which is hinged at the connection between the main discharge channel and the diversion channel, and the edge of the electromagnetic baffle is provided with a sealing strip.

[0007] The spiral conveying pipe has a transparent observation window on its wall, and the impurity identification device includes a high-definition camera and an image processor, with the lens of the high-definition camera aimed at the transparent observation window of the spiral conveying pipe.

[0008] The bottom of the non-conforming material collection box is equipped with a removable filter screen with a pore size of 5mm-8mm.

[0009] The inner wall of the feed hopper is provided with a wear-resistant liner, and the inner wall of the spiral conveying pipe is provided with a wear-resistant lining.

[0010] The feed detection device for preparing nutrient soil provided in this application integrates a moisture detector, a particle size detector, and an impurity identification device in the middle section of a spiral conveyor pipe. This enables simultaneous detection of feed moisture content, particle size, and impurity content, eliminating the need for step-by-step detection of the same batch of feed, significantly shortening the detection cycle, and solving the problems of cumbersome operation and low efficiency of existing single-parameter detection equipment. Furthermore, the spiral conveyor pipe is inclined and fixed to the support frame, and the conveying structure of the spiral blades inside the pipe ensures smooth feed conveying and prevents accumulation and blockage. In addition, the screening mechanism, through the diversion design of the main discharge channel and the diversion channel, can separate qualified and unqualified materials in real time based on the detection results of the detection mechanism. Unqualified materials fall directly into the collection box through the inclined diversion channel, avoiding the subjectivity and lag of manual screening, effectively preventing unqualified raw materials from entering subsequent mixing processes, ensuring the fertility, permeability, and stability of the final nutrient soil product, and reducing the production rework rate.

[0016] Please see Figure 1This application provides a feeding and testing device 1 for preparing nutrient soil. The feeding and testing device 1 includes a support frame 10, a feeding mechanism 20, a testing mechanism 30, and a screening mechanism 40. The feeding mechanism 20 includes a feeding hopper 21 and a spiral conveying pipe 22. The spiral conveying pipe 22 is inclinedly fixed to the support frame 10, and the feeding hopper 21 is fixed to the top of the support frame 10. The bottom outlet of the feeding hopper 21 is sealed and connected to the feeding end of the spiral conveying pipe 22. The testing mechanism 30 is located in the middle section of the spiral conveying pipe 22 and includes a moisture detector 31, a particle size detector 32, and an impurity identification device 33. The detection probe of the moisture detector 31 penetrates the pipe wall of the spiral conveying pipe 22 and extends into the pipe. The particle size detector 32 includes a laser emitter 321 and a laser receiver 322 symmetrically arranged on both sides of the spiral conveying pipe 22. The impurity identification device 33 is fixed above the spiral conveying pipe 22. The screening mechanism 40 is located at the discharge end of the spiral conveyor pipe 22 and includes a main discharge channel 41, a diversion channel 42 and a defective material collection box 43. The main discharge channel 41 is connected to the discharge end of the spiral conveyor pipe 22. The diversion channel 42 is inclined downward and located on the side wall of the main discharge channel 41. The defective material collection box 43 is located below the diversion channel 42.

[0017] Optionally, the bottom of the support frame 10 is provided with brakeable casters. In this embodiment, the spiral conveying pipe 22 is fixed to the support frame 10 at an angle. The spiral conveying pipe 22 enables stable feeding, and the angled setting can extend the detection time and improve the detection accuracy.

[0018] Specifically, the moisture detection element 31 is used to detect the moisture content of the feed in real time. The particle size detection element 32 includes a laser emitter 321 and a laser receiver 322 symmetrically arranged on both sides of the spiral conveying pipe 22, which detects the particle size distribution through the principle of laser diffraction. The impurity identification element 33 includes a high-definition camera and an image processor. The high-definition camera is fixed above the spiral conveying pipe 22 and is used to capture images of the feed inside the pipe in real time and transmit them to the image processor for impurity identification through image comparison.

[0019] Optionally, the moisture detection element 31 is a capacitive moisture sensor with a corrosion-resistant and wear-resistant coating on the surface of its detection probe to avoid damage caused by direct friction with the feed material and extend its service life.

[0020] Specifically, the main discharge channel 41 is connected to the discharge end of the spiral conveyor pipe 22 and is used to convey qualified feed material. The diversion channel 42 is inclined downward and disposed on the side wall of the main discharge channel 41, and the unqualified material collection box 43 is disposed below the diversion channel 42 and is used to collect unqualified feed material.

[0021] Optionally, the screening mechanism 40 further includes a vibrator, which is fixed to the outer wall of the main discharge channel 41 to prevent the feed from getting blocked in the channel and improve the smoothness of the conveying.

[0022] In summary, the feed detection device 1 for preparing nutrient soil provided in this embodiment integrates a moisture detector 31, a particle size detector 32, and an impurity identification device 33 in the middle section of the spiral conveying pipe 22, enabling simultaneous detection of feed moisture content, particle size, and impurity content. This eliminates the need for step-by-step detection of the same batch of feed, significantly shortening the detection cycle and solving the problems of cumbersome operation and low efficiency of existing single-parameter detection equipment. Furthermore, the spiral conveying pipe 22 is tilted and fixed to the support frame 10, and combined with the conveying structure of the spiral blades 221 inside the pipe, ensures smooth feed conveying and prevents accumulation and blockage. In addition, the screening mechanism 40, through the diversion design of the main discharge channel 41 and the diversion channel 42, can separate qualified and unqualified materials in real time based on the detection results of the detection mechanism 30. Unqualified materials fall directly into the collection box through the tilted diversion channel 42, avoiding the subjectivity and lag of manual screening, effectively preventing unqualified raw materials from entering subsequent mixing processes, ensuring the fertility, permeability, and stability of the final nutrient soil product, and reducing production rework rate.

[0023] Please see Figure 2 The spiral conveying pipe 22 is provided with spiral blades 221 inside. The spiral blades 221 are driven to rotate by a drive motor 222. The drive motor 222 is fixed to the bottom of the support frame 10 by a motor base.

[0024] In this embodiment, the spiral blade 221 is driven to rotate by the drive motor 222, which enables continuous and uniform feeding, avoids blockage in the pipe, and ensures the accuracy of the detection data. Furthermore, the drive motor 222 is fixed to the bottom of the support frame 10 via a motor mount, which reduces the impact of operating vibration on detection accuracy and improves the overall structural stability and service life of the nutrient soil feeding detection device.

[0025] Please refer to it again. Figure 2 The screening mechanism 40 also includes an electromagnetic baffle 44, which is hinged to the connection between the main discharge channel 41 and the diversion channel 42, and the edge of the electromagnetic baffle 44 is provided with a sealing strip 441.

[0026] Optionally, the feeding detection device for the nutrient soil further includes a controller. The input terminals of the controller are electrically connected to the moisture detection element 31, the particle size detection element 32, and the impurity identification element 33, respectively, to receive and process the detection data. The output terminals of the controller are electrically connected to the drive motor 222 of the spiral blade 221 and the electromagnetic baffle 44, respectively, to control the speed of the drive motor 222 and the operation of the electromagnetic baffle 44 according to the detection results.

[0027] Alternatively, the electromagnetic baffle 44 is hinged at the connection between the main discharge channel 41 and the diversion channel 42, and can be controlled to flip by the controller to achieve channel switching.

[0028] In this embodiment, the electromagnetic baffle 44 can quickly respond to detection signals to achieve automated channel switching, accurately separating qualified and unqualified materials, and avoiding the lag of manual intervention. Furthermore, the sealing strip 441 provided on the edge of the electromagnetic baffle 44 enhances the sealing at the connection point, preventing material leakage or cross-contamination between qualified and unqualified materials, while also reducing frictional wear between the electromagnetic baffle 44 and the channel, thus improving the operational stability of the screening mechanism 40.

[0029] Please refer to it again. Figure 2 The spiral conveying pipe 22 has a transparent observation window 223 on its wall. The impurity identification device 33 includes a high-definition camera and an image processor. The lens of the high-definition camera is aimed at the transparent observation window 223 of the spiral conveying pipe 22.

[0030] Optionally, the transparent observation window 223 is made of high-temperature resistant tempered glass to ensure clear observation and prevent breakage.

[0031] In this embodiment, the transparent observation window 223 provides a visual channel for impurity detection. The high-definition camera accurately captures the image of the material feeding inside the tube, and the image processor enables rapid identification of impurities. The detection is intuitive and accurate, avoiding problems such as missed detection and false detection caused by manual identification.

[0032] Please refer to it again. Figure 2 The bottom of the non-conforming material collection box 43 is provided with a removable filter screen 431, the filter screen 431 having a pore size of 5mm-8mm.

[0033] In this embodiment, the filter screen 431 can perform secondary screening of unqualified materials, intercepting large impurities while recovering fine raw materials with the required particle size, thus reducing resource waste. Furthermore, the detachable design of the filter screen 431 facilitates regular cleaning of the intercepted impurities, preventing filter clogging from affecting the collection efficiency of unqualified materials and ensuring the continuous and stable operation of the feed detection device 1 for preparing nutrient soil.

[0034] Optionally, the inner wall of the feed hopper 21 is provided with a wear-resistant liner, and the inner wall of the spiral conveying pipe 22 is provided with a wear-resistant lining.

[0035] Optionally, the wear-resistant lining is made of ceramic material, and the thickness of the wear-resistant lining is 2mm-3mm.

[0036] In this embodiment, the wear-resistant liner and the wear-resistant inner lining respectively protect the inner walls of the feed hopper 21 and the spiral conveyor pipe 22, reducing wear on the feed particles, extending service life, and lowering equipment maintenance and replacement costs. Furthermore, it prevents debris generated from inner wall wear from mixing into the feed, thus preventing contamination of raw materials and affecting the detection accuracy of the detection mechanism 30, ensuring the purity of the feed and the reliability of the detection results.
