Description

Technical Field

[0001] The present invention relates to the technical field of sampling and collection, and in particular to a device for collecting animal epidemic disease samples. Background Art

[0002] In the livestock industry, timely disease monitoring and prevention are crucial for protecting animal health, maintaining livestock profitability, and ensuring food safety. To prevent livestock from contracting diseases, regular sampling of livestock diseases is essential. The collection of disease samples is fundamental to disease diagnosis, monitoring, and the development of prevention and control strategies. The quality and accuracy of these samples directly impact subsequent testing results and the effectiveness of epidemic prevention and control efforts.

[0003] The Chinese patent with announcement number CN119374962B discloses a livestock disease sample collection and processing device, including a square cannula, a conical tube at the upper end of the square cannula, a discharge nozzle at the top of the conical tube, a strip opening on one side of the square cannula, a slide sliding on the strip opening, a flap hinged at the lower end of the skateboard, a torsion spring between the flap and the skateboard, a limit block on the flap, a strip limiting groove on the square cannula, a notch on the strip limiting groove, a slider sliding on the skateboard, a flip arm on the slider, a lifting extrusion member on the flip arm, a flap reset member on the side of the square cannula away from the strip opening, a through hole on the outer wall of the square cannula, and a sealing sliding cover on the through hole. Although the above patent can collect livestock manure, the flap needs to be flipped to collect livestock manure. When collecting liquid manure, since the liquid manure is fluid, the liquid manure is easy to overflow the flap due to inertia or gravity during the flipping of the flap, making it difficult to completely collect the sample. This phenomenon not only reduces the integrity of sample collection, but also affects the collection effect.

[0004] The present invention aims to solve the problems existing in the above patents. To this end, a livestock disease sample collection device is proposed, which can completely collect solid feces and liquid feces for sampling, thereby improving sample integrity and sampling effect. Summary of the Invention

[0005] To overcome the problem that the flap must be turned to collect livestock feces, when collecting liquid feces, due to its fluidity, the liquid feces easily overflows the flap due to inertia or gravity during the flap turning process, making it difficult to completely collect the sample. This phenomenon not only reduces the integrity of sample collection but also affects the collection effect. The present invention provides a livestock disease sample collection device that can completely collect solid and liquid feces for sampling, thereby improving sample integrity and sampling effect.

[0006] The present invention is achieved through the following technical solutions:

[0009] Further explanation, the scraping assembly includes a hollow tube that is rotatably mounted on the guide tube, a fixed ring is fixed to the bottom of the hollow tube along the circumferential direction, and a scraper that contacts the elastic cloth is symmetrically connected to the bottom of the fixed ring for scraping off livestock feces attached to the elastic cloth. A torsion spring I is connected between the scraper and the fixed ring, and a transmission assembly is provided between the hollow tube and the screw for driving the hollow tube to rotate.

[0010] To further illustrate, the transmission assembly includes a one-way gear fixedly sleeved on the hollow tube, and a driving gear fixedly sleeved on the screw rod and meshing with the one-way gear.

[0011] Further explanation, the livestock disease sample collection equipment also includes a support assembly, which includes a fixed plate fixedly mounted on the cylinder, and support rods are connected to the fixed plate at evenly spaced intervals along the circumference to support and limit the cylinder, and a torsion spring II is connected between the support rod and the fixed plate, and a locking assembly is provided between the support rod and the cylinder for locking the support rod.

[0012] To further illustrate, the support assembly also includes a rubber block fixed to the end of the support rod for increasing friction with the ground.

[0013] To further illustrate, the locking assembly includes an L-shaped block fixed to the inner side of the support rod, and a locking frame is connected to the cylinder through damping sliding to lock the L-shaped block.

[0015] The beneficial effects of the present invention are:

[0016] 1. First, hold the cylinder so that the spiral conveying shaft is inserted into the livestock manure, then start the stepper motor to drive the screw to rotate forward, and the screw drives the movable frame to move downward through the threaded block. The movable frame drives the elastic cloth to move downward to cover the livestock manure. The elastic cloth pushes the livestock manure centrally so that the livestock manure contacts the spiral conveying shaft. Then start the drive motor to drive the spiral conveying shaft to reverse. The reverse rotation of the spiral conveying shaft drives the livestock manure to move upward for collection. In this way, whether the livestock manure is solid or liquid, it can be driven upward by the spiral conveying shaft for transportation, thereby completely collecting the livestock manure for sampling, improving the sample integrity and sampling effect.

[0017] 2. Under the action of the scraper, every time the elastic cloth moves upward to reset, the scraper rotates to scrape off the livestock feces attached to the elastic cloth, and the scraped livestock feces falls down to the ground. In this way, a large amount of livestock feces attached to the elastic cloth can be prevented from affecting subsequent use and carrying, thereby ensuring that the elastic cloth is clean and convenient for subsequent use and carrying.

[0018] 3. Under the action of the support rod, whenever livestock manure is collected, the support rod can support and limit the device, making the device more stable to use. In this way, the operator does not need to hold the cylinder all the time to make the spiral conveying shaft drive the livestock manure to move for transportation, which makes it more convenient for the operator to use the device.

A spiral conveying shaft 4 is rotatably connected between the top of the cylinder 1 and the upper part of the guide tube 2. When the spiral conveying shaft 4 rotates, the spiral conveying shaft 4 can drive the livestock feces to move upward for transportation. The bottom end of the spiral conveying shaft 4 is located outside the guide tube 2, and a driving motor 5 is installed on the top outside the cylinder 1. The driving motor The output shaft end of the machine 5 is fixedly connected to the top of the spiral conveying shaft 4, and a fixed frame 6 is fixedly sleeved on the lower part of the outer side surface of the cylinder 1. A movable frame 7 is slidably sleeved on the fixed frame 6. An elastic cloth 8 is fixedly connected circumferentially between the lower inner part of the movable frame 7 and the lower part of the outer side surface of the cylinder 1. A driving assembly is provided between the cylinder 1 and the movable frame 7. The driving assembly is used to drive the movable frame 7 to move downward. The movable frame 7 drives the elastic cloth 8 to move downward to cover the livestock manure, so that the livestock manure is pushed centrally to contact the spiral conveying shaft 4 and is transported and collected. A scraping assembly is provided on the cylinder 1. When the scraping assembly is in operation, the scraping assembly can scrape off the livestock manure attached to the elastic cloth 8.

[0032] See also Figure 3 As shown, the driving assembly includes a threaded block 9, a screw 91 and a stepper motor 92. The threaded block 9 is fixedly connected to the right side of the top of the movable frame 7, and the screw 91 is vertically rotatably connected to the right side of the fixed frame 6. The screw 91 is threadedly connected to the threaded block 9. A stepper motor 92 is installed on the lower part of the right side of the outer side of the cylinder 1, and the output shaft end of the stepper motor 92 is fixedly connected to the top of the screw 91.

[0033] See also Figure 4-Figure 6 As shown, the scraping assembly includes a hollow tube 10, a fixed ring 101, a scraper 102, a torsion spring Ⅰ1021 and a transmission assembly. The lower part of the outer side of the guide tube 2 is rotatably covered with a hollow tube 10. The bottom of the hollow tube 10 is fixedly connected to a fixed ring 101 along the circumferential direction. The bottom of the fixed ring 101 is symmetrically rotated and connected to a scraper 102. The scraper 102 is in contact with the elastic cloth 8. When the scraper 102 rotates, the scraper 102 can scrape off the livestock feces attached to the elastic cloth 8. The scrapers 102 on both sides at the rear are connected to the fixed ring 101 by a torsion spring Ⅰ1021, and a transmission assembly is provided between the upper part of the hollow tube 10 and the screw 91, which can drive the hollow tube 10 to rotate; the transmission assembly includes a one-way gear 103 and a driving gear 104, and the one-way gear 103 is fixedly sleeved on the upper part of the outer surface of the hollow tube 10 along the circumferential direction, and the driving gear 104 is fixedly sleeved on the upper part of the screw 91, and the driving gear 104 is engaged with the one-way gear 103.

[0034] First, the operator holds the cylinder 1 and drives the screw conveying shaft 4 to move, so that the screw conveying shaft 4 is inserted into the livestock manure, and then starts the stepper motor 92 to rotate forward. The forward rotation of the stepper motor 92 drives the screw 91 to rotate forward. The forward rotation of the screw 91 drives the threaded block 9 to move downward through the thread. The downward movement of the threaded block 9 drives the movable frame 7 to move downward. The downward movement of the movable frame 7 drives the elastic cloth 8 to move downward. Since one end of the elastic cloth 8 is fixed to the cylinder 1, the elastic cloth 8 moves downward in a cone shape. The downward movement of the elastic cloth 8 drives the scraper 102 to swing downward, the torsion spring Ⅰ1021 is compressed, and the elastic cloth 8 continues to move downward to cover the livestock manure and push the livestock manure toward the spiral conveying shaft 4. At the same time, the forward rotation of the screw 91 also drives the drive gear 104 The one-way gear 103 rotates forward and rotates forward, and the one-way gear 103 rotates idly, and the idling of the one-way gear 103 does not drive the hollow tube 10 to rotate. Then the stepping motor 92 is turned off, and the screw 91 stops driving the movable frame 7 to move downward through the threaded block 9. The movable frame 7 stops driving the elastic cloth 8 to move downward. The screw 91 also stops driving the driving gear 104 to rotate forward, and the driving gear 104 stops driving the one-way gear 103 to rotate idly. Then the driving motor 5 is started to drive the spiral conveying shaft 4 to reverse, and the spiral conveying shaft 4 reverses to drive the livestock manure to move upward for transportation. The livestock manure is transported to the guide tube 2. In this way, whether the livestock manure is solid or liquid, it can be driven upward by the spiral conveying shaft 4 for transportation, thereby completely collecting the livestock manure. Sampling, improve sample integrity and sampling effect, when the livestock manure is transported, turn off the drive motor 5, the drive motor 5 stops driving the spiral conveying shaft 4 to reverse, then start the stepping motor 92 to reverse and drive the screw 91 to reverse, the screw 91 reverses and drives the movable frame 7 to move upward through the threaded block 9, the movable frame 7 drives the elastic cloth 8 to move upward, the elastic cloth 8 moves upward and stops limiting the scraper 102, due to the action of the torsion spring Ⅰ1021, the scraper 102 swings upward and is always close to the elastic cloth 8, and at the same time the screw 91 also drives the drive gear 104 to reverse, the drive gear 104 reverses and drives the one-way gear 103 to rotate forward, the one-way gear 103 rotates forward and drives the hollow tube 10 to rotate forward, the hollow tube 10 rotates forward and drives the fixing ring 101 to rotate forward, the fixing ring 101 rotates forward The scraper 102 is driven to rotate forward, and the scraper 102 rotates forward to scrape the livestock feces attached to the elastic cloth 8, and the scraped feces fall downward to the ground. In this way, a large amount of livestock feces attached to the elastic cloth 8 can be prevented from affecting subsequent use and carrying, thereby ensuring that the elastic cloth 8 is clean and convenient for subsequent use and carrying. When the movable frame 7 moves upward and resets, the stepper motor 92 is turned off, the screw 91 stops driving the movable frame 7 to move upward through the threaded block 9, and the movable frame 7 stops driving the elastic cloth 8 to move upward. At the same time, the hollow tube 10 stops driving the scraper 102 to rotate forward, and then the negative pressure bottle 3 is controlled to start to extract the livestock feces in the guide tube 2 for collection, thereby completing the collection of livestock feces. Then, the cylinder body 1 is held to pick up the device, and the negative pressure bottle 3 is twisted to separate from the guide tube 2.Subsequent testing of livestock fecal samples can then be performed.

[0035] See also Figure 7-Figure 9 As shown, the animal husbandry disease sample collection device also includes a support assembly installed on the cylinder 1, the support assembly includes a fixing plate 11, a support rod 111, a torsion spring II 1111, a rubber block 112 and a locking assembly. The middle part of the outer side of the cylinder 1 is fixedly sleeved with a fixing plate 11, and six support rods 111 are connected to the fixing plate 11 at evenly spaced intervals along the circumferential direction. The support rods 111 can support and limit the cylinder 1. A torsion spring II 1111 is connected between the support rod 111 and the fixing plate 11. The bottom end of the support rod 111 is fixedly connected to a rubber block 112. The rubber block 1 12 can increase the friction with the ground, making the support rod 111 more stable to use. A locking assembly is provided between the support rod 111 and the cylinder 1. When the locking assembly is in operation, the locking assembly can lock the support rod 111; the locking assembly includes an L-shaped block 113 and a locking frame 114. The upper part of the inner side surface of the six support rods 111 is fixedly connected with an L-shaped block 113, and the middle part of the outer side surface of the cylinder 1 is connected with a locking frame 114 through damping sliding. The locking frame 114 can lock the L-shaped block 113 to complete the locking limit of the support rod 111.

[0036] At the same time, due to the action of the rubber block 112, the friction force with the ground can be increased, thereby making the support rod 111 more firmly support and limit the position, and then the livestock manure collection can begin. When the collection of livestock manure is completed, the device is picked up and the six support rods 111 are pushed to swing inward and reset. The torsion spring II 1111 is compressed, and the support rods 111 swing inward, driving the L-shaped block 113 and the rubber block 112 to swing inward and reset. The L-shaped block 113 is reset to correspond to the locking frame 114, and then the locking frame 114 is pushed downward to cover the L-shaped block 113. The locking frame 114 locks the L-shaped block 113 and also completes the locking of the support rods 111. The support rods 111 are retracted, making it easier for the operator to carry and store the device. In this way, the operator does not need to hold the cylinder 1 all the time so that the screw conveying shaft 4 drives the livestock manure to move for transportation, thereby making it more convenient for the operator to use the device.

[0037] See also Figure 10 As shown, the animal husbandry disease sample collection equipment also includes a limiting component installed on the cylinder 1, the limiting component includes a horizontal plate 12, a support ring 13 and a protective pad 14, the horizontal plate 12 is fixedly mounted on the upper outer surface of the cylinder 1, the support ring 13 is fixedly connected to the top rear side of the horizontal plate 12, the negative pressure bottle 3 is located on the support ring 13, the support ring 13 can support and limit the negative pressure bottle 3 to reduce the pressure at the connection between the negative pressure bottle 3 and the guide tube 2, the inner side of the support ring 13 is fixedly connected to the protective pad 14 along the circumferential direction, the protective pad 14 is in contact with the negative pressure bottle 3, and the protective pad 14 can protect the negative pressure bottle 3.

[0038] When the negative pressure bottle 3 extracts and collects livestock feces from the guide tube 2, the support ring 13 can support and limit the negative pressure bottle 3 through the protective pad 14. The support function of the support ring 13 can reduce the pressure at the connection between the negative pressure bottle 3 and the guide tube 2. When the negative pressure bottle 3 is removed from the guide tube 2, the negative pressure bottle 3 and the protective pad 14 are separated. After the livestock feces in the negative pressure bottle 3 are poured out for inspection, the negative pressure bottle 3 is returned to the support ring 13 to contact the protective pad 14, and the negative pressure bottle 3 and the guide tube 2 are locked together. The protective pad 14 protects the negative pressure bottle 3. In this way, the negative pressure bottle 3 can be used more stably.
