DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] 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.

[0022] Please see attached Figure 1 -Attached Figure 4 A heavy metal detection device for agricultural products includes a detection box 1, the base of the detection box 1 is made of metal material, the outer wall of the detection box 1 is made of glass material, the interior and bottom surface of the detection box 1 are both provided with detection components, the detection component includes a crushing box 2 arranged inside the detection box 1, the bottom surface of the crushing box 2 is provided with a plurality of water inlet holes 210, the bottom surface of the detection box 1 is provided with an electronic scale 201, the outer wall of the detection box 1 is printed with scale lines 202, the top surface of the crushing box 2 is provided with a lifting plate 203, the left and right sides of the outer wall of the detection box 1 are fixed with fixing bars 204, the top surface of the fixing bar 204 is fixed with a screw 205, and the lifting plate 203 and the outer wall of the screw 205 are movably sleeved.

[0023] In the embodiment, the top surface of the crushing box 2 is threadedly connected with a top cover 206, and a double-axis motor is fixed on the top surface of the top cover 206. The bottom output shaft of the double-axis motor penetrates and extends to the interior of the crushing box 2, and a crushing knife 207 is fixed to the bottom output shaft end of the driving motor. The top output shaft of the double-axis motor penetrates and extends to the top surface of the lifting plate 203, and a driving gear 208 is fixed to the top output shaft end of the double-axis motor. The top surface of the lifting plate 203 is rotatably connected to driven gears 209 near the left and right ends. The driven gear 209 is threaded with the outer wall of the screw 205, and the outer wall of the connecting screw 205 is not threaded at a distance of five centimeters from the bottom to the top. Vegetables are placed into the crushing box 2 and weighed using an electronic scale 201. Subsequently, detection reagents are placed into the detection box 1 and the amount of the detection reagents is determined by the scale line 202 to ensure that the ratio of the detection reagents to the vegetables reaches the best detection ratio and the detection effect is guaranteed. The crushing box 2 can then be raised and lowered. After the detection reagents and vegetables in the detection box 1 are mixed and reacted completely, the crushing box 2 together with the crushed vegetables and the reacted reagents are separated. At this time, the staff can directly observe the reagent color and the sediment through the detection box 1. Without the obstruction of the vegetables, it is convenient for better observation and the detection accuracy is increased.

[0024] In the embodiment, a spring 3 is provided on the outer wall of the screw rod 205. The length of the spring 3 is five centimeters. The bottom end of the spring 3 is fixed to the top surface of the fixing bar 204. By setting and using the spring 3, it is ensured that the threaded hole of the driven gear 209 is always in contact with the threaded bottom surface of the screw rod 205, ensuring that when the driven gear 209 rotates in the opposite direction, the driven gear 209 can be quickly re-threadedly connected to the screw rod 205.

[0025] In the embodiment, a blocking cover 4 is fixed to the outer wall of the top cover 206, and a sealing ring is fixed to the inner wall of the detection box 1. The outer wall of the blocking cover 4 and the inner wall of the sealing ring are interference fit. By setting and using the blocking cover 4, in combination with the sealing ring on the inner wall of the detection box 1, the interior of the detection box 1 can be kept closed when the vegetables are crushed to prevent the reagent liquid from splashing out.

[0026] In the embodiment, a threaded seat 5 is fixed to the top surface of the electronic scale 201, and the detection box 1 is threadedly connected to the threaded seat 5. Through the setting and use of the threaded seat 5, it is convenient to disassemble the detection box 1 and the electronic scale 201, and to clean the detection box 1.

[0027] In an embodiment, a support rod 6 is fixed between the lifting plate 203 and the top cover 206. The setting and use of the support rod 6 can prevent the output shaft of the dual-axis motor from being used as a support point when the lifting plate 203 is lifted to pull the top cover 206, thereby preventing the dual-axis motor from being damaged.

[0028] Working principle: When in use, first start the dual-axis motor to drive the driving gear 208 to rotate in the opposite direction. Under the meshing transmission action of the driving gear 208 and the two driven gears 209 through the toothed belt, the driven gear 209 rotates. Since the spring 3 applies elastic force to the bottom surface of the lifting plate 203, the internal thread of the driven gear 209 always fits with the bottom surface of the screw 205 thread. When the driven gear 209 rotates in the opposite direction, the driven gear 209 is threadedly connected with the screw 205 again, and the lifting plate 203 drives the top cover 206, the crushing box 2 and the blocking cover 4 to rise. At this time, the sealing cover 4 is lifted. The plug cover 4 is separated from the sealing ring inside the detection box 1, and then the staff rotates to separate the crushing box 2 and the top cover 206, and puts the crushing box 2 back into the detection box 1. At this time, the vegetables to be tested are placed in the crushing box 2, and the weight of the vegetables is recorded by the electronic scale 201. Then, the crushing box 2 and the top cover 206 are reinstalled. At this time, the detection reagent is placed in the detection box 1, and the amount of the detection reagent is determined by the scale line 202, so as to ensure that the ratio of the detection reagent to the vegetable reaches the best detection ratio and the detection effect is guaranteed. Then the dual-axis electric The machine driving gear 208 rotates forward so that the lifting plate 203 drives the top cover 206, the crushing box 2 and the blocking cover 4 to reset. At this time, the internal thread of the driven gear 209 is disengaged from the thread of the screw 205 again, and the crushing knife 207 rotates forward and crushes the vegetables. The reagent is mixed with the crushed vegetables through the water inlet hole 210, and the vegetables and the detection reagent are mixed more evenly by the rotating crushing knife 207. After the vegetables and the detection reagent are completely reacted, the double-axis motor is started to rotate in the opposite direction, and the lifting plate 203 drives the top cover 206, the crushing box 2 and the blocking cover 4 to rise. At this time, the vegetables are separated from the detection reagents, and the staff can directly observe the reagent color and sediment through the detection box 1. Without the obstruction of the vegetables, it is convenient for better observation and increased detection accuracy. The setting and use of the support rod 6 can prevent the output shaft of the dual-axis motor from being used as a support point when the lifting plate 203 rises and pulls the top cover 206, thereby preventing damage to the dual-axis motor. The setting and use of the blocking cover 4, combined with the sealing ring on the inner wall of the detection box 1, ensures that the interior of the detection box 1 remains closed when the vegetables are crushed to prevent the reagent liquid from splashing out.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
