Description

Technical Field

[0001] This utility model relates to the field of agricultural product testing and sampling technology, specifically to an agricultural product testing and sampling device capable of quantitative feeding. Background Technology

[0002] Agricultural product sampling and testing refers to the process of extracting representative samples from a batch of agricultural products in accordance with scientific standards and analyzing them through physical, chemical, or biological methods to assess their quality, safety, and compliance. This step is an important foundation for agricultural product quality and safety supervision, trade acceptance, and scientific research.

[0003] Existing agricultural product testing and sampling devices require placing the agricultural products to be tested inside a collection cylinder, allowing them to fall downwards under gravity, and then transporting them to the placement cylinder via a conveyor belt for compression testing. Due to the irregular shape of the agricultural products and their tendency to accumulate towards the outlet of the collection cylinder due to gravity, this accumulation can easily cause blockages at the outlet, preventing the products from being conveyed onto the conveyor belt. Therefore, a quantitatively dispensing agricultural product testing and sampling device is needed to reduce the accumulation of agricultural products inside the collection cylinder at the outlet. Utility Model Content

[0004] The purpose of this invention is to provide a sampling device for detecting agricultural products that can quantitatively dispense materials, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sample collection device for agricultural product testing with quantitative feeding capability, comprising a fixed frame, a cylinder mounted above the fixed frame, a squeezing disc mounted at the output end of the cylinder, the squeezing disc located inside the fixed frame, a placement cylinder mounted at the bottom inner side of the fixed frame, the placement cylinder located directly below the squeezing disc, the inner diameter of the placement cylinder being the same as the outer diameter of the squeezing disc, a guide groove mounted on one side of the placement cylinder, the guide groove being mounted on the inner wall of the fixed frame, the end of the guide groove away from the placement cylinder being mounted inside a fixed base, the fixed base being fixedly mounted on the outer wall of the fixed frame, a receiving cylinder mounted on the upper side of the fixed base, a transmission mechanism mounted inside the fixed base, a clearing mechanism mounted inside the receiving cylinder, and the transmission mechanism located at the bottom of the clearing mechanism.

[0006] Preferably, the unblocking mechanism includes a turntable, which is movably installed at the bottom of the storage cylinder. The outer diameter of the turntable is the same as the inner diameter of the storage cylinder. Multiple temporary storage slots are evenly distributed on the turntable. Through holes are provided at the bottom of the storage cylinder and on the upper side of the fixed base. The diameter of the through holes is the same as the diameter of the temporary storage slots. The bottom of the through holes communicates with the inside of the guide trough.

[0007] Preferably, multiple sets of fixed sleeves are evenly installed on the upper side of the turntable, and ball bearings are movably installed on the top of the fixed sleeves. The fixed sleeves are located in the gap between the two temporary storage slots.

[0008] Preferably, the transmission mechanism includes a motor, which is mounted on the bottom of the fixed base. A transmission rod is mounted on the output end of the motor, and a drive disk is mounted on the end of the transmission rod away from the motor. The drive disk is located in a cavity opened inside the fixed base. A movable plate is movably mounted on one side of the drive disk, and a fixed column is mounted on the top of the movable plate. The other end of the fixed column passes through the storage cylinder and is mounted on the bottom of the turntable.

[0009] Preferably, a connecting rod is installed at the upper end of the transmission rod, the connecting rod is located below the drive disc, and a fixed post is installed at the end of the connecting rod away from the transmission rod, the mounting post being inserted inside the movable plate.

[0010] Preferably, the movable plate has four movable slots evenly distributed, each movable slot having one side that is arc-shaped, and the inserting post is inserted inside the movable slot.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When the quantitative feeding agricultural product testing and sampling device is in use, the inserting column on the transmission mechanism is intermittently inserted into the movable groove, thereby driving the turntable to rotate intermittently, thus achieving the effect of quantitative feeding. At the same time as the turntable rotates, the ball bearings, under the mutual cooperation of the push force of the turntable and the friction force between the ball bearings and the agricultural products, can push the agricultural products to be tested accumulated inside the collection cylinder to move their position while conveying the agricultural products downward. Thus, when the quantitative feeding agricultural product testing and sampling device is in use, it plays the role of intermittently conveying agricultural products downward in a quantitative manner, while clearing the accumulated agricultural products to be tested inside the collection cylinder.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 This utility model provides a technical solution: a sampling device for detecting agricultural products with quantitative feeding, including a fixed frame 1, a cylinder 5 installed above the fixed frame 1, a squeezing plate 4 installed at the output end of the cylinder 5, the squeezing plate 4 located inside the fixed frame 1, a placement cylinder 3 installed at the bottom inner side of the fixed frame 1, the placement cylinder 3 located directly below the squeezing plate 4, the inner diameter of the placement cylinder 3 being the same as the outer diameter of the squeezing plate 4, a guide groove 2 installed on one side of the placement cylinder 3, the guide groove 2 being installed on the inner wall of the fixed frame 1, the end of the guide groove 2 away from the placement cylinder 3 being installed inside the fixed base 6, the fixed base 6 being fixedly installed on the outer wall of the fixed frame 1, and a storage cylinder 7 installed on the upper side of the fixed base 6;

[0021] In practice, the agricultural products to be tested are placed inside the storage cylinder 7, and then fall from the bottom of the storage cylinder 7 and slide down along the guide chute 2 until they fall into the placement cylinder 3. After the sensor inside the placement cylinder 3 senses the weight of the agricultural products, it transmits the signal to the data terminal, and the cylinder 5 is activated to push the extrusion plate 4 downward, thereby squeezing out the juice of the agricultural products stored inside the placement cylinder 3 for sampling and testing.

[0022] Please see Figure 2 and Figure 4 The unblocking mechanism 8 includes a turntable 801, which is movably installed at the bottom of the storage cylinder 7. The outer diameter of the turntable 801 is the same as the inner diameter of the storage cylinder 7. Multiple temporary storage slots 804 are evenly opened on the turntable 801. Through holes 805 are opened at the bottom of the storage cylinder 7 and on the upper side of the fixed base 6. The diameter of the through hole 805 is the same as the diameter of the temporary storage slot 804. The bottom of the through hole 805 communicates with the inside of the guide groove 2.

[0023] In practice, while the transmission mechanism 9 is running, it will drive the turntable 801 to rotate inside the storage cylinder 7. Since the multiple temporary storage slots 804 opened on the turntable 801 have a certain depth, agricultural products can be accumulated inside the temporary storage slots 804 during the rotation of the turntable 801. When the temporary storage slot 804 rotates to the position corresponding to the through hole 805, the agricultural products accumulated in the temporary storage slot 804 can be transported from the through hole 805 to the guide trough 2, thereby improving the transmission efficiency in the sampling process of agricultural product testing, and thus improving the efficiency of agricultural product testing.

[0024] Please see Figure 3 Multiple sets of fixed sleeves 802 are evenly installed on the upper side of the turntable 801. A ball bearing 803 is movably installed on the top of the fixed sleeve 802. The fixed sleeve 802 is located in the gap between the two temporary storage slots 804.

[0025] In practice, with the cooperation of the fixed sleeve 802 and the ball bearing 803, when the turntable 801 rotates inside the storage cylinder 7, the thrust generated by the rotation of the storage cylinder 7 and the friction between the ball bearing 803 and the agricultural products work together to make the ball bearing 803 rotate inside the fixed sleeve 802. As the ball bearing 803 rotates, it rubs against the surface of the agricultural products, thereby pushing the agricultural products to move inside the storage cylinder 7 and reducing the accumulation of agricultural products inside the storage cylinder 7, which could cause blockage of the temporary storage tank 804 and the through hole 805.

[0026] Please see Figure 5 The transmission mechanism 9 includes a motor 901, which is mounted on the bottom of the fixed base 6. A transmission rod 902 is mounted on the output end of the motor 901. A drive disk 903 is mounted on the end of the transmission rod 902 away from the motor 901. The drive disk 903 is located in a cavity opened inside the fixed base 6. A movable plate 905 is movably mounted on one side of the drive disk 903. A fixed column 906 is mounted on the top of the movable plate 905. The other end of the fixed column 906 passes through the storage tube 7 and is mounted on the bottom of the turntable 801.

[0027] In practice, through the cooperation between the motor 901, transmission rod 902, drive disc 903, connecting rod 904, movable plate 905, fixed column 906, movable slot 907 and mounting column 908, the connecting rod 904 can drive the mounting column 908 to push the movable plate 905 forward when the motor 901 starts, so that the temporary storage slot 804 opened on the turntable 801 is aligned with the through hole 805, and the crops are conveyed downward.

[0028] Furthermore, one side of the drive disk 903 is recessed inward into an arc shape, the radius of which is the same as the radius of the movable plate 905. The radii of the four recessed grooves on the movable plate 905 are the same as the radius of the drive disk 903, thus preventing the drive disk 903 and the movable plate 905 from getting stuck during operation.

[0029] Please see Figure 5 and Figure 6 A connecting rod 904 is installed on the upper end of the transmission rod 902. The connecting rod 904 is located on the lower side of the drive disc 903. A fixed post 906 is installed on the end of the connecting rod 904 away from the transmission rod 902. An insert post 908 is inserted into the movable plate 905. Four movable slots 907 are evenly opened on the movable plate 905. One side of each movable slot 907 is arc-shaped. The insert post 908 is inserted into the movable slot 907.

[0030] In practice, the motor 901 drives the transmission rod 902, drive disc 903 and connecting rod 904 to rotate, thereby adjusting the position of the insertion post 908. When the drive disc 903 rotates to a certain angle, the insertion post 908 will be inserted into the movable slot 907 by the inertia of rotation. Then, as the drive disc 903 rotates, the insertion post 908 will push the movable plate 905 to rotate to a certain angle, thereby aligning the temporary storage slot 804 with the through hole 805, and transmitting the agricultural products downward to achieve the effect of intermittent quantitative feeding.

[0031] In summary, when using this quantitative agricultural product testing and sampling device, the agricultural product to be tested is placed inside the receiving cylinder 7, allowing it to fall from the bottom of the cylinder 7 and slide down along the guide chute 2 until it falls into the placement cylinder 3. The sensor inside the placement cylinder 3 senses the weight of the agricultural product and transmits a signal to the data terminal, activating the cylinder 5 to push the extrusion disc 4 downwards, thereby squeezing out the juice from the agricultural product stored inside the placement cylinder 3 for sampling and testing. This is existing technology and will not be elaborated upon further. The insertion post 908 on the transmission mechanism 9 is intermittently inserted into the movable slot 907. This causes the turntable 801 to rotate intermittently, thereby achieving the effect of quantitative feeding. While the turntable 801 rotates, the ball bearings 803, under the combined action of the thrust of the turntable 801 and the friction between the ball bearings and the agricultural products, can push the agricultural products to be tested accumulated inside the collection cylinder 7 to move their positions while conveying the agricultural products downwards. Thus, when the quantitative feeding agricultural product testing and sampling device is used, it plays the role of intermittently conveying the agricultural products downwards in a quantitative manner, while clearing the accumulated agricultural products to be tested inside the collection cylinder 7. The contents not described in detail in this description belong to the prior art known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
