Description

Technical Field

[0001] The present invention relates to the technical field of animal medicine, and particularly to a rectal feces collection device for sheep. Background Art

[0002] Feces examination of sheep is an important basis for reflecting feed conversion rate, intestinal microorganism monitoring, and parasite monitoring during the feeding process of sheep.

[0003] At present, feces sampling of sheep mainly relies on direct extraction and surface picking methods. For direct extraction, after the sheep is fixed, the hand is inserted into the rectum of the sheep to extract feces. If this method is not properly operated, it is likely to cause certain harm to the sheep and is also likely to cause epidemic infections of sheep and humans. Moreover, the feces picked up from the ground are easily contaminated, and the microorganisms and parasites in the feces are also easily killed, resulting in data distortion and thus affecting the test results.

[0004] In view of the above problems, the existing devices for cattle and sheep rectum on the market mostly have complex structures, are not convenient for moving inside the rectum for sampling, and require multiple people to assist in the operation, consuming manpower and material resources. Based on this, there is an urgent need to propose a simpler and more effective rectal feces collection device for sheep. Summary of the Invention

[0005] To solve the technical problems raised in the background art, the present invention provides a rectal feces collection device for sheep.

[0006] The present invention is implemented by the following technical solutions: A rectal feces collection device for sheep includes a collection cylinder and an inserter. The collection cylinder and the inserter are detachably connected through a connection mechanism.

[0007] The inserter is made of silica gel. The head of the inserter is bullet-shaped. A notch is opened at a position near the head of the inserter, and a scraper is movably arranged at the notch. The scraper and the connection mechanism are connected through a telescopic unit to control the scraper to retract or extend out of the corresponding notch.

[0008] The collection cylinder is a cylindrical structure with an open top, and an adjustment mechanism is further installed on one side of it. The adjustment mechanism is used to control the telescopic unit to work.

[0009] With the above structure, after the inserter is inserted into the rectum to a certain depth, the adjustment mechanism can be used to control the telescopic unit to work, so that the scraper extends out of the inserter, and then by selecting and pulling the inserter, the feces on the inner wall of the rectum can be effectively cleaned.

[0010] As a further improvement of the above solution, the connection mechanism includes a connection sleeve fixed inside the collection cylinder, an inner tube located in the inserter. The bottom end of the inner tube extends out of the inserter and is screwed to the connection sleeve. The inner tube and the connection sleeve are internally connected, and the telescopic unit is connected to the inner tube.

[0011] As a further improvement of the above solution, the telescopic unit includes a telescopic tube. One end of the telescopic tube is connected to the inner end of the scraper, and the other end of the telescopic tube is connected to the inner tube. Air holes communicating with the telescopic tube are formed on the inner tube housing, and the length of the telescopic tube changes with the change of air pressure.

[0012] As a further improvement of the above solution, an auxiliary reset unit is also installed on the outer side of the inner tube. The auxiliary reset unit is used to drive the telescopic tube to return to its initial length when shortening. The auxiliary reset unit includes a sleeve sleeved on the outer side of the inner tube, a clamping plate fixed on the edge of the sleeve, and a sleeve plate fixed on the inner end of the scraper. A plurality of connecting rods parallel to the telescopic tube are fixed on the sleeve plate. The end of the connecting rod movably penetrates through the clamping plate and is connected with a limiting block. A return spring is sleeved on the outer side of the connecting rod between the limiting block and the clamping plate.

[0013] Through the auxiliary reset unit, when the air pressure in the inner tube decreases, the elastic force of the return spring can be used to drive the telescopic tube to return to its initial length, so as to pull back the scraper inward and make it enter the inserter.

[0014] As a further improvement of the above solution, the head is also made of silica gel. A docking hole connecting to the top of the inner tube is formed on one side of the head, and an annular hoop is also sleeved between the head and the top of the inserter to make the connection between the head and the inserter more firm.

[0015] As a further improvement of the above solution, a sealing ring is arranged on the inner wall of the notch. The scraper is made of silica gel, and the end surface of the scraper is a smooth arc surface.

[0016] As a further improvement of the above solution, the adjusting mechanism includes an installation cylinder fixed in the collection cylinder. A piston channel is arranged in the installation cylinder. A piston plate is installed in the piston channel. One side of the piston plate is fixed with a piston rod. The end of the piston rod penetrates through the through hole on the collection cylinder and is connected with a button. An elastic return module is installed on the outer side of the piston rod;

[0017] An air hole one communicating its interior and the piston channel is formed on the connecting sleeve. A one-way valve one is arranged in the air hole one;

[0018] An air hole two communicating the piston channel and the outside is formed on the installation cylinder. A one-way valve two is arranged in the air hole two;

[0019] And when the piston plate is pushed forward, the one-way valve two guides the external air into the piston channel, and the one-way valve one guides the air in the piston channel into the connecting sleeve and the inner tube.

[0020] As a further improvement of the above scheme, the elastic return module includes a cylinder fixed relatively to the inner wall of the piston channel and a circular plate, a columnar spring sleeved on the outside of the piston rod, and the circular plate is sleeved on the outside of the piston rod, the cylinder and the circular plate are coaxially fixed, and one end of the columnar spring is in contact with the inner wall of the piston channel or the button in the mounting cylinder.

[0021] The above-mentioned adjustment mechanism makes it convenient for people to hold the collecting barrel with one hand, and use fingers to press the adjustment mechanism to change the length of the telescopic unit to control the extended length of the scraper.

[0022] As a further improvement of the above solution, a vent hole is provided at the bottom of the collecting tube, a countersink is provided at the outer end of the vent hole, and a valve unit is installed at the countersink to discharge the gas in the inner tube, thereby reducing the air pressure in the inner tube and facilitating the resetting of the scraper.

[0023] As a further improvement of the above scheme, the valve unit includes a limit plate arranged at the countersunk hole, a rotating shaft rotatably connected to the limit plate, a sealing plate connected to the inner end of the rotating shaft, and a shift plate connected to the outer end of the rotating shaft, wherein: by shifting the shift plate to drive the rotating shaft to rotate, the sealing plate can block or open the air leakage hole.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The sampling device proposed in the present invention can be operated with one hand. The inserter is sent into the corresponding position in the rectum of the animal by holding the collecting tube, and the button can be repeatedly pressed with a single finger. It is convenient for one person to operate with one hand, and the work is convenient and efficient.

[0026] The present invention increases the air pressure in the inner tube to drive the telescopic tube to extend and push out the scraper. When the scraper can contact the inner wall of the rectum, the inserter is rotated and pulled out to scrape the feces on the inner wall and make the feces fall into the collection tube for storage. It is convenient for the inserter to move in the rectum and work stably and reliably. BRIEF DESCRIPTION OF THE DRAWINGS
