Description
Technical Field
[0001] This utility model relates to the technical field of soybean sampling equipment, specifically, to a sampling machine for crop testing. Background Technology
[0002] As soybeans become increasingly important in the global food supply chain, ensuring their quality during storage has become a key challenge for the agricultural and food industries. During storage, soybeans can be affected by mold, pests, and environmental factors such as temperature and humidity, leading to quality decline or even spoilage. Therefore, regular inspection of soybean warehouses to monitor their quality is crucial. Traditional inspection methods rely primarily on manual sampling, which is not only inefficient but also difficult to comprehensively cover all areas of large warehouses, potentially leading to the overlooking of underlying problems.
[0003] While existing crop sampling machines can conveniently and quickly sample and test soybeans, solving the problem of inconvenient sampling in previous soybean testing machines, their small sample holding frame volume makes them unsuitable for batch soybean testing scenarios, thus limiting sampling efficiency.
[0004] Furthermore, when faced with long-distance sampling scenarios, the ease of operation is greatly reduced, and the applicability is limited.
[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0006] In view of the problems in related technologies, this utility model proposes a sampling machine for crop testing to overcome the above-mentioned technical problems existing in the existing related technologies.
[0007] Therefore, the specific technical solution adopted by this utility model is as follows: A sampling machine for crop testing includes a sampling tube; a sampling component disposed inside the sampling tube for accurate collection and independent storage of soybean samples from different depths and batches; a support tube disposed between the sampling tube and the sampling component, and located at the tail end of the sampling tube; a handrail disposed on the outer circumference of the sampling tube; several fixing blocks disposed on the outer circumference of the sampling tube; and a first through hole opened on one side of the fixing blocks.
[0008] Optionally, the inner circumferential wall of the sampling cylinder is provided with several sliding grooves that mate with the sampling component; the inner circumferential wall of the sampling cylinder is provided with several first engaging grooves and second engaging grooves arranged circumferentially from top to bottom. The several first engaging grooves and several second engaging grooves located on the same sliding groove are arranged in a relative structure. The several first engaging grooves and several second engaging grooves are all arranged in a staggered structure.
[0009] Optionally, the sampling assembly includes a push rod disposed inside the sampling cylinder. The outer circumference of the push rod is provided with several sleeves, and the outer circumference of each sleeve is provided with several locking blocks that mate with the sliding groove and the first and second locking grooves. The bottom end of the push rod is provided with a layer-breaking cone that mates with the sampling cylinder. The top end of the push rod is provided with a cross-shaped rotating block, and the top of the cross-shaped rotating block has several second through holes. The inner diameter of the sampling cylinder is the same as the outer diameter of the layer-breaking cone.
[0010] Optionally, connecting rods are fitted onto the inner circumference of the three sets of first through holes located on the same straight line, and the connecting rods are fixed to the fixing blocks by nuts; fixing seats are fitted onto the outer circumference of the other side of several connecting rods, and handles are symmetrically arranged on the outer circumference of the fixing seats, and the connecting rods are fixed to the fixing seats by nuts. A linkage rod is inserted in the middle of the fixing seat, and a collar is fitted onto the outer circumference of the bottom of the linkage rod. Several connecting blocks are arranged on the outer circumference of the collar, and a U-shaped seat is provided at one end of the connecting block to cooperate with the cross rotating block. A bolt that cooperates with the second through hole is provided on the U-shaped seat; a pin is provided on the outer circumference of the other side of the linkage rod.
[0011] The beneficial effects of this utility model are as follows: 1. This utility model has a reasonable and reliable structure and is simple to operate. With the help of the sampling component and sampling cylinder, the push rod drives the layer-breaking cone to adapt to the sampling cylinder, ensuring penetration of soybean layers of different densities while preventing sample loss. Furthermore, the snap-fit positioning allows for stable lifting and rapid removal of the push rod, reducing transfer losses and cross-contamination, and ensuring testing accuracy. By adding a connecting rod, fixing base, and linkage rod structure, the operational difficulties in long-distance sampling scenarios are effectively solved. It not only meets the needs of conventional short-distance sampling but can also efficiently adapt to long-distance and special environmental sampling scenarios, improving the versatility and practicality of the sampling machine.
[0012] 2. This utility model, through the design of a sampling component, utilizes a push rod to drive a layer-breaking cone that engages with the sampling cylinder. The outer diameter of the layer-breaking cone matches the inner diameter of the sampling cylinder, ensuring sufficient penetration of the layer-breaking cone into the soybean accumulation layer, easily breaking through soybean structures of varying densities, while preventing sample loss due to soybean leakage from gaps during sampling. Simultaneously, a snap-fit positioning system allows for stable raising, lowering, and fixing of the push rod within the sampling cylinder. After sampling, operators simply adjust the snap-fit block to disengage from the snap-fit groove, quickly withdrawing the push rod to retrieve the sample. This effectively reduces sample loss and cross-contamination during transfer, providing strong assurance for the accuracy of subsequent testing results. Attached Figure Description

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0017] According to an embodiment of the present invention, a sampling machine for crop testing is provided.
[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0019] Example 1
[0020] like Figures 1-4 The diagram shows a preferred embodiment of a sampling machine for crop testing according to this utility model. The sampling machine includes a sampling cylinder 1; a sampling component 2 disposed inside the sampling cylinder 1 for accurate collection and independent storage of soybean samples from different depths and batches; a support cylinder 3 disposed between the sampling cylinder 1 and the sampling component 2, located at the tail end of the sampling cylinder 1; a handrail 4 disposed on the outer circumference of the sampling cylinder 1; several fixing blocks 5 disposed on the outer circumference of the sampling cylinder 1; and a first through hole 9 opened on one side of each fixing block 5.
[0021] In one embodiment, the inner circumferential wall of the sampling cylinder 1 is provided with a plurality of sliding grooves 6 that cooperate with the sampling component 2; the inner circumferential wall of the sampling cylinder 1 is provided with a plurality of first engaging grooves 7 and second engaging grooves 8 arranged circumferentially from top to bottom. The plurality of first engaging grooves 7 and the plurality of second engaging grooves 8 located on the same sliding groove 6 are arranged in a relative structure. The plurality of first engaging grooves 7 and the plurality of second engaging grooves 8 are all arranged in a staggered structure.
[0022] In one embodiment, the sampling assembly 2 includes a push rod 201 disposed inside the sampling cylinder 1. The outer circumference of the push rod 201 is provided with several sleeves 202, and the outer circumference of each sleeve 202 is provided with several locking blocks 203 that cooperate with the sliding groove 6 and the first locking groove 7 and the second locking groove 8. The bottom end of the push rod 201 is provided with a layer-breaking cone 204 that cooperates with the sampling cylinder 1. The top end of the push rod 201 is provided with a cross-shaped rotating block 205, and the top of the cross-shaped rotating block 205 has several second through holes 206. The inner diameter of the sampling cylinder 1 is the same as the outer diameter of the layer-breaking cone 204.
[0023] like Figures 1-4 As shown, in practical application, the staff first installs the sleeve 202 and the snap-fit block 203 at the preset position on the outer circumference of the push rod 201, then assembles the layer-breaking cone 204 and the cross rotating block 205 at the beginning and end of the push rod 201 respectively, and inserts the assembled sampling component 2 into the sampling cylinder 1 through the matching and cooperation between the snap-fit block 203 and the inner wall sliding groove 6 of the sampling cylinder 1, and installs the support cylinder 3 on the top of the push rod 201, and finally completes the overall assembly of the sampling machine.
[0024] The staff first pushes the cross rotating block 205 to drive the push rod 201, so that the locking block 203 moves along the slide groove 6 to the bottom. Then, the cross rotating block 205 is rotated clockwise to drive the locking block 203 into the second locking groove 8, so that the layer breaking cone 204 protrudes out of the sampling tube 1, preparing for subsequent sampling.
[0025] Staff members hold handle 4 and insert sampling tube 1 into the soybean pile. The layer-breaking cone 204 first penetrates the soybean grain layer. As sampling tube 1 goes deeper into the target depth, the soybeans automatically flow into the independent compartment inside the sampling tube 1 through the reserved gap, completing the sample collection of the deep layer of soybeans.
[0026] After sampling, the operator rotates the cross-shaped rotating block 205 counterclockwise, causing the locking block 203 to return to the slide groove 6. Then, the push rod 201 is lifted upwards. When the push rod 201 is limited by the support cylinder 3, the cross-shaped rotating block 205 is rotated counterclockwise again, causing the locking block 203 to engage with the first locking groove 7, thus stably storing the soybean sample in the compartment. The sampling cylinder 1 is then removed, and the cross-shaped rotating block 205 is rotated in the opposite direction to release the soybean sample from the compartment layer by layer.
[0027] Example 2
[0028] like Figure 1 , Figure 2 and Figures 5-8 The diagram shown is a structural schematic of a sampling machine for crop testing according to another preferred embodiment of the present invention. This embodiment of the sampling machine for crop testing is based on Embodiment 1: Three sets of first through holes 9 located on the same straight line are each fitted with a connecting rod 10 on their inner circumference. The connecting rod 10 is fixed to the fixing block 5 by a nut. The outer circumference of several connecting rods 10 is fitted with a fixing seat 11. The outer circumference of the fixing seat 11 is symmetrically provided with handles 12. The connecting rod 10 is fixed to the fixing seat 11 by a nut. A linkage rod 13 is inserted in the middle of the fixing seat 11. A collar 14 is fitted on the bottom outer circumference of the linkage rod 13. Several connecting blocks 15 are provided on the outer circumference of the collar 14. One end of the connecting block 15 is provided with a U-shaped seat 16 that cooperates with the cross rotating block 205. A bolt 17 that cooperates with the second through hole 206 is provided on the U-shaped seat 16. A pin 18 is provided on the outer circumference of the other side of the linkage rod 13.
[0029] It should be noted that the connection between the connecting rod 10 and the nut has threads that mate with the nut, ensuring that the two can be securely screwed together.
[0030] In practical applications, when performing long-distance sampling, the staff first inserts several connecting rods 10 into the first through hole 9 of the fixing block 5, and fixes the connecting rods 10 and the fixing block 5 with nuts. Then, the fixing seat 11 is placed on the other end of the connecting rod 10 and locked with nuts. The linkage rod 13 is inserted through the middle of the fixing seat 11. A collar 14 is fitted on the outer circumference of the bottom of the linkage rod 13 and fixed with bolts. Next, a U-shaped seat 16 with its opening facing the cross rotating block 205 is installed and rotated into the cross rotating block 205. The reserved hole of the U-shaped seat 16 is aligned with the second through hole 206 of the cross rotating block 205 and the bolts are tightened to achieve a rigid connection. A pin 18 is installed on the outer circumference of the linkage rod 13 on the side away from the collar 14 to complete the assembly of the transmission structure.
[0031] The staff pushes the linkage rod 13, which drives the cross rotating block 205 through the linkage structure to drive the push rod 201, so that the locking block 203 moves along the slide groove 6 to the bottom. The staff drives the cross rotating block 205 by rotating the pin 18 clockwise, so that the locking block 203 is locked into the second locking groove 8, so that the layer breaking cone 204 protrudes outside the sampling tube 1, preparing for subsequent sampling.
[0032] The staff held the handle 12 with both hands to keep the sampling tube 1 stable, inserted the sampling tube 1 into the soybean pile, and pressed down with both hands. The layer-breaking cone 204 first penetrated the soybean grain layer. As the sampling tube 1 went deeper into the target depth, the soybeans automatically flowed into the independent compartment inside the cavity through the gap reserved in the sampling tube 1, completing the sample collection of the deep layer of soybeans.
[0033] After sampling, the operator rotates the pin 18 counterclockwise to drive the cross-shaped rotating block 205, causing the locking block 203 to return to the slide groove 6. The push rod 201 is then lifted upwards via the pin 18. When the push rod 201 is limited by the support cylinder 3, the cross-shaped rotating block 205 is rotated counterclockwise again, causing the locking block 203 to engage in the first locking groove 7, thus stably storing the soybean sample in the compartment. The sampling cylinder 1 is then removed, and the pin 18 is rotated in the opposite direction to drive the cross-shaped rotating block 205, allowing the soybean sample in the compartment to be released layer by layer.
[0034] based on Figures 1-8 Both the sampling machine structures in Example 2 and Example 1 can achieve the required functions.
[0035] In summary, by utilizing the above-mentioned technical solution of this utility model, and with the sampling component 2 working in conjunction with the sampling cylinder 1, the push rod 201 drives the layer-breaking cone 204 to adapt to the sampling cylinder 1, ensuring penetration of soybean accumulation layers of different densities while preventing sample leakage. Furthermore, the snap-fit positioning enables stable lifting and rapid removal of the push rod, reducing transfer losses and cross-contamination, and ensuring testing accuracy. By adding the connecting rod 10, the fixing seat 11, and the linkage rod 13, the operational challenges of long-distance sampling scenarios are effectively solved. This not only meets the needs of conventional short-distance sampling but also efficiently adapts to long-distance and special environmental sampling scenarios, improving the versatility and practicality of the sampling machine. This invention features a sampling component 2. A push rod 201 drives a layer-breaking cone 204 to cooperate with the sampling cylinder 1. The outer diameter of the layer-breaking cone 204 matches the inner diameter of the sampling cylinder 1, ensuring sufficient penetration of the soybean accumulation layer during insertion. This allows for easy penetration of soybean structures of varying densities while preventing sample loss due to soybean leakage from gaps. Simultaneously, a snap-fit positioning system allows for stable lifting and fixing of the push rod 201 within the sampling cylinder 1. After sampling, the operator simply adjusts the snap-fit block 203 to disengage from the snap-fit groove, quickly removing the push rod to retrieve the sample. This effectively reduces sample loss and cross-contamination during transfer, providing a strong guarantee for the accuracy of subsequent testing results.
