Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer production and processing technology, and in particular to an organic fertilizer sampler. Background Technology

[0002] Organic fertilizer is a type of fertilizer made from organic matter such as animal and plant remains, excrement, and biological waste through processing. It has advantages such as being natural, environmentally friendly, providing comprehensive nutrients, and improving soil structure. The sources of organic fertilizer are very wide, including human excrement, manure, compost, green manure, oilseed cake, and biogas fertilizer.

[0003] In the processing of organic fertilizer, sampling and testing through a sampling device can better understand the treatment effect at each stage and adjust the production process in a timely manner. For example, the prior art Chinese patent announcement number "CN220729670U" discloses a granular sampler, which relates to the field of fertilizer production technology. It includes a handle with a discharge hole on the handle, a sampling tube installed on one side of the handle, a fixing block installed on the inner wall of the discharge hole, a screw feeding rod rotatably installed on the fixing block, a motor installed at one end of the screw feeding rod, the motor installed on the inner wall of the discharge hole, and the other end of the screw feeding rod rotatably installed on the sampling tube. This invention, through the design of a spiral feeding rod, a motor, and a sampling box, allows for efficient fertilizer sampling. When fertilizer needs to be sampled, the sampling tube is inserted into the fertilizer, the motor is started, and the rotation of the motor drives the spiral feeding rod to rotate, thus conveying the fertilizer to the discharge port. The fertilizer falls directly into the sampling box for collection. When a large amount of fertilizer needs to be sampled, multiple samplings by staff are unnecessary, making the process convenient and quick. Furthermore, the direct fall of the sampled fertilizer into the sampling box prevents spillage, improving sampling efficiency.

[0004] In actual operation, the spiral feeder rod feeds and samples the sample box, but the sample box cannot weigh the conveyed sample. Failure to weigh may lead to inaccurate sampling, which in turn affects the representativeness of the sample, the accuracy of the test results, and the completeness of the sampling record. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that cannot weigh and sample materials, and to propose an organic fertilizer sampler.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an organic fertilizer sampler, including a sampling tube, a sampling device inside the sampling tube, a fixing plate and a support plate fixedly connected to the periphery of the sampling tube, and a sampling box on the side of the support plate through a fixing frame, and the sampling box is fixed by a fixing component.

[0008] A spring force measuring component is provided between the fixing frame and the support plate, and the spring force measuring component is used to weigh the fertilizer in the sampling box.

[0009] Furthermore, the sampling tube is provided with an inlet and a outlet at the top and bottom of its periphery, respectively. The outlet is provided in a corresponding manner to the sampling box. The upper surface of the sampling box is an open structure. The sampling device includes a conveying auger, which is rotatably connected to the sampling tube by a driving device.

[0010] Furthermore, the fixing element is a positioning glass bead, the fixing frame has a notch on three sides, and at least one positioning glass bead is embedded in the fixing frame at the notch. The sampling box abuts against the fixing frame, the sampling tube and the positioning glass bead.

[0011] Furthermore, the spring force measuring assembly includes a spring, and through grooves are provided on both sides of the end face of the support plate. The bottom surface of the through grooves connects to the support plate to form a sliding groove. One side of the fixing frame has an upwardly extending extension on both sides. The extension is slidably connected to the through groove through the sliding groove, and the spring is suspended between the extension and the top of the through groove by a connecting rod.

[0012] Furthermore, the connecting rod is threaded to the side of the support plate, one end of the connecting rod extends into the through groove and engages with the hook-shaped part of the spring end, and the other end of the connecting rod is provided with a butterfly-shaped part.

[0013] Furthermore, a scale is provided on the back of the support plate on one side of the through groove, and an indicator is provided on the back of the extension, with the indicator end of the indicator corresponding to the scale.

[0014] The organic fertilizer sampler proposed in this utility model has the following advantages: This utility model uses a driven conveying auger to transport organic fertilizer into the sampling box for sampling. During the sampling process, as the sample in the sampling box gradually increases, the sampling box drives the fixing frame to move downward under the action of gravity. While the fixing frame is moving, the weight of the sample in the sampling box can be observed through the indicator and scale. Accurate weighing can avoid sampling too much or too little, thereby saving resources and reducing waste. Furthermore, weighing can help to sample quickly and accurately, improving the efficiency of the entire testing and production process. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 An organic fertilizer sampler includes a sampling tube 1, a sampling device 2 is provided inside the sampling tube 1, a fixing plate 3 and a support plate 4 are fixedly connected to the periphery of the sampling tube 1, and a sampling box 6 is provided on the side of the support plate 4 through a fixing frame 5. The fixing frame 5 fixes the sampling box 6 through a fixing member.

[0022] A spring force measuring component 7 is provided between the fixing frame 5 and the support plate 4. The spring force measuring component 7 is used to weigh the fertilizer in the sampling box 6.

[0023] It should be added that the fixing plate 3 is fixed to the outer periphery of one end of the sampling tube 1. An oblong hole is provided at the corner of the fixing plate 3. After the sampling tube 1 is placed in the storage container, the fixing plate 3 and the storage container are fixed by means of locking bolts passing through the oblong hole, so as to achieve the purpose of fixing the sampling device for easy sampling.

[0024] Furthermore, the sampling tube 1 is provided with an inlet 11 and a discharge port 12 at the top and bottom of its periphery, respectively. The discharge port 12 is provided in correspondence with the sampling box 6. The upper surface of the sampling box 6 is an open structure. The sampling device 2 includes a conveying auger 21, which is rotatably connected to the sampling tube 1 by a driving device.

[0025] Specifically, the driving device is a motor, which is fixed on the other side of the support plate 4, and the shaft end of the motor is connected to the end of the conveying auger 21. The feed port 11 passes through the top of the sampling tube 1, but does not connect to the discharge port 12. The motor drives the conveying auger 21 to feed the sampling box 6.

[0026] Furthermore, the fixing component is a positioning glass bead 51, the fixing frame 5 has a notch on three sides, and at least one positioning glass bead 51 is embedded in the fixing frame 5 at the notch. The sampling box 6 abuts against the fixing frame 5, the sampling tube 1 and the positioning glass bead 51.

[0027] More specifically, the spring force measuring assembly 7 includes a spring 71, and through grooves 41 are provided on both sides of the end face of the support plate 4. The bottom surface of the through grooves 41 connects to the support plate 4 to form a sliding groove. The fixing frame 5 has upwardly extending extensions 52 on both sides of one side. The extensions 52 are slidably connected in the through grooves 41 through the sliding grooves, and the spring 71 is hung between the extensions 52 and the top of the through grooves 41 by a connecting rod 72.

[0028] It is worth mentioning that the principle of the spring force measuring component 7 can be referred to the spring force gauge in the prior art;

[0029] It should be noted that the working principle of the spring balance is based on Hooke's Law, that is, within the elastic limit, the elongation (or compression) of the spring is proportional to the force applied. The spring force measuring component 7 can only work within the elastic limit of the spring 71, and the scale on the dial 73 is pre-calibrated according to the spring constant of the spring 71 and the expected measurement range. When the spring 71 is elongated or compressed, the magnitude of the corresponding force can be read by the position indicated by the indicator 74 on the dial 73. This means that springs 71 with different tension coefficients correspond to different scales on the dial 73.

[0030] Furthermore, the springs 71 on both sides have the same structure. Under normal circumstances, the indicating end of the indicating part 74 corresponds to the zeroing degree of the dial 73.

[0031] In general, the connecting rod 72 is threaded to the side of the support plate 4, one end of the connecting rod 72 extends into the through groove 41 and engages with the hook-shaped part at the end of the spring 71, and the other end of the connecting rod 72 is provided with a butterfly-shaped part 721.

[0032] Specifically, after rotating the connecting rod 72 to disengage it from the support plate 4, the spring 71 can be unlocked, making it easy to disassemble and replace the spring 71, and also easy to disassemble and assemble the fixing bracket 5.

[0033] Finally, the back of the support plate 4 is provided with a dial 73 on one side of the through groove 41, and the back of the extension 52 is provided with an indicator 74, the indicator end of the indicator 74 corresponding to the dial 73.

[0034] Working method: When working, the sampling tube 1 is placed in the storage container, or the sampling device and the storage container can be fixed together by the fixing plate 3. Then, the motor drives the conveying auger 21 to rotate, and the sample is conveyed to the sampling box 6 through the discharge port 12.

[0035] As the sample material in the sampling box 6 gradually increases, the sampling box 6 drives the fixing frame 5 to move the extension part 52 downward under the action of gravity. While the extension part 52 moves, the weight of the sample material is determined by the indicator position between the indicator part 74 and the scale 73.

[0036] Then, press the positioning glass bead 51 to retract it, and the sampling box 6 can be disassembled and assembled.

[0037] After prolonged use, rotating the connecting rod 72 to detach it from the support plate 4 will unlock the spring 71, making it easy to disassemble and replace the spring 71, and also making it easy to disassemble and assemble the fixing bracket 5.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
