Description

Technical Field

[0001] The invention belongs to the field of animal husbandry and livestock breeding devices, and relates to a device for measuring feed conversion efficiency, in particular to a device for measuring conversion efficiency of mutton sheep. Background Art

[0002] Feed conversion rate refers to the amount of feed consumed per unit of livestock product or weight gain.

[0003] TMR is the abbreviation of Total Mixed Rations. It is a nutritionally balanced diet obtained by fully mixing roughage, concentrated feed and various nutritional additives chopped (kneaded) to appropriate lengths in accordance with the nutritional needs of ruminants at different physiological stages.

[0004] The existing device for measuring the conversion efficiency of mutton sheep breeding is mainly used for measuring the conversion efficiency of pellet feed. The device is mainly composed of an inductive identification ear tag device, a weighing device, a feed trough and a sensor. After the mutton sheep is identified by the ear tag before feeding, the weighing device and the sensor work together to record the weight changes of the mutton sheep and feed, and transmit the data to the background for analysis and calculation of the feed conversion efficiency.

[0005] Existing devices for measuring the conversion efficiency of mutton sheep breeding have the following disadvantages when used to measure the TMR feed conversion efficiency: (1) After TMR is placed in the feed trough, multiple sheep take turns to eat. Due to the picky eating behavior of sheep, it is impossible to ensure uniform feeding, and the measurement accuracy is low; (2) The amount of feed placed is difficult to control. Multiple sheep take turns to eat, and the mixed feed is easily contaminated by sheep saliva. Due to the sheep's preference for cleanliness, the remaining feed is wasted; (3) In the open feed trough, the sheep will take the feed out of the trough when eating, causing waste, and it is inconvenient to remove the remaining feed. (4) The single induction identification ear tag device is not convenient for the information and intelligent feeding control of sheep. Summary of the invention

[0024] 1. This feed conversion efficiency measuring device for mutton sheep realizes the function of measuring the conversion efficiency of pellet feed and TMR feed, meets the needs of diversified feed measurement under different feeding conditions, and broadens the practical scope of the device.

[0025] 2. This feed conversion efficiency measuring device for mutton sheep, after TMR is put into the feed trough, multiple sheep take turns to eat, thus avoiding the problem of low measurement accuracy due to the picky eating behavior of sheep and the inability to ensure uniform feeding.

[0026] 3. This feed conversion efficiency measuring device for mutton sheep uses ear tag recognition and photoelectric induction recognition to accurately identify sheep. The information and intelligent system controls the amount of feed for each sheep each time to ensure the accuracy of the feed, avoiding the difficulty in controlling the amount of feed, multiple sheep taking turns to feed, the mixed feed is easily contaminated by sheep saliva, and the waste of residual feed due to the sheep's preference for clean behavior. . When working, the photoelectric induction recognizes whether there are sheep entering, the ear tag recognizes the sheep's code, and the feeding door automatically opens after double recognition, and the appropriate amount of feed is put into the feed basin, and the sheep puts its head into the feeding opening to eat.

[0027] 4. The TMR conversion efficiency measuring device for mutton sheep is designed to have a gourd-shaped structure with a large upper end and a small lower end. This ensures that the sheep's head can eat after being inserted into the feeding port, while limiting the activity space of the sheep's head, effectively preventing the feed from being carried out and reducing the waste of feed.

[0028] 5. The feed conversion efficiency measuring device for mutton sheep has a weight weighing mechanism to realize the weight weighing of the sheep. The width and length of the placement corridor are adjustable to meet the measurement needs of sheep of different sizes. In addition, the setting of the placement corridor plays a guiding role on the one hand, so that the sheep entering can eat smoothly; on the other hand, it can block the external environment to prevent the sheep from being disturbed.

[0029] 6. This feed conversion efficiency measuring device for meat sheep effectively avoids the problem of inaccurate weight measurement caused by other sheep not being measured stepping on it by detachably laying several metal plates at the front end of the fence on the bottom trough; the detachable design also facilitates the length adjustment of the fence.

[0030] 7. This feed conversion efficiency measuring device for mutton sheep has a horizontal and vertical conveyor belt on the feeding mechanism for the purpose of feeding and feeding respectively. The digging shovel and nail rake arranged on the vertical conveyor belt ensure that all the pellets and grass are caught, ensuring that the fed feed is evenly mixed.

[0031] 8. The feed conversion efficiency measuring device for mutton sheep is provided with a rotating feeding door. On the one hand, when the feeding door is in the lowered state, it can form the surrounding wall of the storage box together with the side wall plates on both sides. After the feed is fed, it can be guided to the transverse conveyor belt by the inclined surface. At this time, the limiting beam abuts against the rear end of the side wall plate to play a limiting role; on the other hand, when the rotating feeding door is flipped upward, the limiting beam overlaps the upper end of the side wall plate. At this time, the angle iron touches the proximity switch, causing the transverse drive motor and the longitudinal drive motor to reverse, thereby achieving the purpose of conveniently removing the remaining feed.

[0032] 9. The feed conversion efficiency measuring device for mutton sheep ensures the stable connection between the feed basin and the feed scale by sliding the feed basin of the feed weighing mechanism onto the feed scale and positioning it by pins on both sides, thereby ensuring the accuracy of the measurement data.

[0033] 10. This feed conversion efficiency measuring device for mutton sheep facilitates the monitoring of feeding conditions through the setting of the observation window, and the installed acrylic window panel avoids the leakage of feed.

[0034] 11. The present invention is scientifically and reasonably designed, and has the advantages of being able to ensure balanced feeding, uniform feeding, feed saving, accurate measurement, cleanliness and hygiene, information and intelligent control, and easy implementation. It is a highly innovative device for measuring the conversion efficiency of pellets and TMR feed for mutton sheep. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The feeding opening is a gourd-shaped structure with a large upper end and a small lower end.

[0055] The automatic feeding door is composed of a reduction motor 12, an overrunning clutch 29, a driving arm plate 27 driven by the reduction motor, and a feeding door plate 4. The overrunning clutch is driven and installed on the driving shaft of the reduction motor, and an end cover 28 is installed on the overrunning clutch by screws. The driving arm plate is composed of a main frame and a connecting portion formed on the upper side of the main frame. The main frame and the connecting portion are integrally formed, and the outer contour of the main frame is adapted to the structure of the feeding port. A feeding door plate is installed on the main frame, and the connecting portion is connected to the end cover by screws. By designing the automatic feeding door as a structure combining a reduction motor and an overrunning clutch, when the feeding door plate rotates and lifts up, the reduction motor transmits power to the overrunning clutch and then to the driving arm plate, so that the feeding door plate is opened; when the feeding door plate is closed, the driving shaft of the reduction motor is separated from the overrunning clutch, and the driving arm plate slowly rotates downward by its own gravity, avoiding the chuck problem caused by the sheep's head not being extended in time, and protecting the sheep from harm.

[0056] The ear tag recognition mechanism is composed of a mounting frame 2 and an ear tag identifier 3. A mounting long hole is provided on the front wall plate, a mounting frame is mounted at the mounting long hole by screw adjustment, an ear tag identifier is mounted on the lower end surface of the mounting frame, and the ear tag identifier is electrically connected to the reduction motor of the automatic feeding door.
