Description

Technical Field

[0001] The utility model relates to the field of food detection, and specifically relates to a beef freshness detection device. Background Art

[0002] Beef is rich in nutrition and has a good taste, and is deeply loved by consumers. However, beef is easily contaminated and deteriorated. During storage, with the proliferation of microorganisms and a series of physical and chemical changes, the freshness of beef decreases.

[0003] At present, the detection methods for beef freshness mainly include observing color, smelling odor, touching feeling, checking viscosity and testing elasticity, which are applicable to household or daily life.

[0004] However, for some beef processing enterprises, in order to ensure that the processed beef will not deteriorate, it is usually necessary to use a detection device to detect the freshness of the received beef during transportation, so as to judge the quality and storage time of the beef. However, for the convenience of detection, a detection container is usually placed in the detection device. After the beef sample is placed in the detection container, the color of the beef sample is detected by a sensor or the gas emitted by the beef sample is received to achieve the purpose of detection. However, since the beef sample is placed in the detection container, blood stains will remain in the container. If the blood stains solidify in the detection container after the detection, it is not convenient for the staff to take it out and clean it, which may affect subsequent use. Content of the Utility Model

[0005] Therefore, in order to solve the above deficiencies, the utility model provides a beef freshness detection device here. The detection device can facilitate the removal of the detection tray for cleaning through the detection tray movably arranged on the telescopic mechanism, preventing inconvenience in cleaning after the blood stains solidify, and the detection tray can be automatically brought into the detection chamber for detection through the telescopic mechanism, ensuring that the detection will not be affected by the external environment.

[0006] The utility model is realized as follows. A beef freshness detection device is constructed, including a detection chamber with an opening on one side and a switch door movably arranged at the opening end;

[0007] A telescopic mechanism is arranged inside the detection chamber and the telescopic direction is pointed at the switch door;

[0008] A detection tray is movably arranged on the telescopic mechanism for placing the beef sample to be detected;

[0009] Several detection sensing devices are arranged at the top inside the detection chamber to detect the beef sample placed in the detection tray.

[0010] Specifically, the detection chamber includes a support table and a receiving frame arranged on the support table. The side of the receiving frame is open. The top of the opening and closing door panel is hinged to the top of the open end of the side of the receiving frame. A traction rope for synchronous movement is connected between the opening and closing door panel and the telescopic mechanism. Several support pulleys are also arranged on the top of the receiving frame. One end of the traction rope is fixed on the outer side of the opening and closing door panel, and the other end passes through the support pulley and is fixed to the telescopic end of the telescopic mechanism.

[0011] Specifically, the telescopic mechanism includes a linear telescopic device and a support ring. The linear telescopic device is arranged on the outer side of the receiving frame and its telescopic end passes through the receiving frame and inserts into the interior. The support ring is fixed on the telescopic end of the linear telescopic device and is horizontally arranged. A guide post passing through the side of the receiving frame is also arranged on the outer side of the support ring.

[0012] Specifically, the detection and sensing device includes a color vision sensor and a gas sensor. The color vision sensor is arranged on the inner top of the receiving frame above the support ring. A lighting fixture is also arranged on the side of the color vision sensor. The gas sensor is arranged on one side of the inner top of the receiving frame. The detection and sensing device and the lighting fixture are respectively connected to the display screen on the top of the receiving frame through connecting lines to maintain communication.

[0013] Specifically, an air flow channel is also arranged in the detection chamber. The intake pipe of the air flow channel is arranged on the outer side of the bottom of one end of the detection chamber and is communicated with the interior of the detection chamber. The exhaust holes of the air flow channel are opened on the top of the other end of the detection chamber. The gas sensor is arranged on the inner top of the detection chamber between the exhaust hole and the support ring.

[0014] Specifically, the detection tray includes a lower support tray and an upper support tray connected by a connecting column. Both the lower support tray and the upper support tray are arc-shaped frame structures that are recessed downward. The lower support tray is placed on the support ring, and the upper support tray is used to place beef samples and ventilation holes are evenly opened on the upper support tray.

[0015] The utility model has the following beneficial effects:

[0016] By arranging the detection chamber and the opening and closing door panel that can be opened on the side of the detection chamber, the detection device can solve the problem that the detection result of beef samples is easily affected by external environmental reasons during detection. After closing the opening and closing door panel during detection, the influence of the external environment on the detection result of beef samples can be greatly reduced, and at the same time, it is convenient to open the opening and closing door panel to take and place beef samples.

[0017] By setting the telescopic mechanism inside the detection chamber and the detection tray movably arranged on the telescopic mechanism, this detection device can solve the problem that blood stains on the outside of beef samples remain in the tray and are not easy to take out and clean, which affects subsequent use. The detection tray can be directly taken out for overall cleaning, facilitating subsequent detection. At the same time, the telescopic mechanism can automatically send out or send in the detection tray to facilitate taking and placing and detection.

[0018] By setting an air flow channel, this detection device can solve the problem that the internal gas is not easy to flow during detection, resulting in incorrect detection data. By introducing air flow into the interior, it is convenient for the gas to contact the beef sample and transfer the odor of the beef sample to the sensor position, thus facilitating detection to ensure the detection quality.

[0019] By setting lighting fixtures, this detection device solves the problem that the internal light is too dim and not convenient for detection, thus facilitating the detection of the color and luster of beef samples through sensors.

[0020] By setting a towing rope, this detection device solves the problem that the opening and closing door panel cannot be linked with the telescopic mechanism. Through the setting of the towing rope, when the telescopic mechanism extends, the opening and closing door is automatically opened to facilitate taking and placing the detection tray and beef samples. When the telescopic mechanism retracts, the opening and closing door is automatically closed to facilitate detection. Brief Description of the Drawings

[0031] As described in the background art, the freshness of beef needs to be detected after transportation and reception. After the existing detection equipment puts the beef sample for detection, the blood stains, sewage, etc. on the beef sample solidify in the detection container and are not easy to clean.

[0032] For the above reasons, please refer to the attached Figure 1 and the attached Figure 2 , the present invention provides a beef freshness detection device, including a detection chamber, one side of which is open and an opening and closing door panel 3 is movably arranged at the opening end;

[0033] A telescopic mechanism is arranged inside the detection chamber and keeps the telescopic direction pointing to the opening and closing door panel 3;

[0034] A detection tray 11 is movably arranged on the telescopic mechanism for placing the beef sample to be detected;

[0035] Several detection sensing devices are arranged at the top inside the detection chamber to detect the beef sample placed in the detection tray 11.

[0036] Please refer to the attached Figure 4 or the attached Figure 5, specifically, the detection chamber includes a support table 1 and a receiving frame 2 provided on the support table 1. The side of the receiving frame 2 is open. The top of the opening and closing door panel 3 is hinged to the top of the open end of the side of the receiving frame 2. A towing rope 9 for synchronously moving it is connected between the opening and closing door panel 3 and the telescopic mechanism. Several support pulleys 8 are also provided on the top of the receiving frame 2. One end of the towing rope 9 is fixed on the outer side of the opening and closing door panel 3, and the other end passes through the support pulley 8 and is fixed to the telescopic end of the telescopic mechanism.

[0037] Please continue to refer to the appendix Figure 4 and the appendix Figure 5 , specifically, the telescopic mechanism includes a linear telescopic device 13 and a support ring 10. The linear telescopic device 13 is provided on the outer side of the receiving frame 2 and its telescopic end passes through the receiving frame 2 and inserts into the interior. The support ring 10 is fixed on the telescopic end of the linear telescopic device 13 and is horizontally arranged. A guide post 14 passing through the side of the receiving frame 2 is also provided on the outer side of the support ring 10.

[0038] Furthermore, the linear telescopic device can preferably be a mechanism with a slower telescopic speed (such as a gear and rack transmission mechanism), which can avoid causing harm to the staff due to the instant opening of the opening and closing door panel caused by too fast telescopic speed during telescoping.

[0039] , specifically, the detection and sensing device includes a color vision sensor 6 and a gas sensor 7. The color vision sensor 6 is provided on the inner top of the receiving frame 2 above the support ring 10. A lighting fixture 5 is also provided on the side of the color vision sensor 6. The gas sensor 7 is provided on one side of the inner top of the receiving frame 2. The detection and sensing device and the lighting fixture 5 are respectively connected to the display screen 4 on the top of the receiving frame 2 through connection lines to maintain communication.

[0040] Furthermore, the connection line is used to supply power to the lighting fixture and the detection and sensing device, and at the same time can transmit the data during detection to the display screen.

[0041] Please refer to the appendix Figure 3 and the appendix Figure 4 , specifically, an air flow channel is also provided in the detection chamber. The intake pipe 12 of this air flow channel is provided on the outer side of the bottom of one end of the detection chamber and is communicated with the interior of the detection chamber. The exhaust holes 15 of the air flow channel are opened on the top of the other end of the detection chamber. The gas sensor 7 is provided on the inner top of the detection chamber between the exhaust holes 15 and the support ring 10.

[0042] Furthermore, the lighting fixture and the intake pipe can also be linked with the telescopic mechanism, that is, when the telescopic mechanism extends, the lighting fixture and the intake pipe are closed, and when the telescopic mechanism retracts, the lighting fixture and the intake pipe are opened.

[0043] Please refer to the appendix Figure 6, specifically, the detection tray 11 includes a lower support plate 11.1 and an upper support plate 11.3 connected by a connecting column 11.2. Both the lower support plate 11.1 and the upper support plate 11.3 are arc-shaped frame structures that are recessed downward. The lower support plate 11.1 is placed on the support ring 10, and the upper support plate 11.3 is used to place the beef sample and is evenly provided with ventilation holes thereon.

[0044] As described in the above technical features, setting the ventilation holes in the upper support plate can facilitate the contact between the air flow and the beef sample, thereby transmitting the odor upward to the sensor position. At the same time, setting the lower support plate can prevent the blood stains and sewage outside the beef sample from flowing into the interior of the detection chamber through the ventilation holes, resulting in the need to clean the interior of the detection chamber subsequently.

[0045] During the use of this detection device, first, start the main switch of the device, and the display screen 4 and each component inside the detection chamber are powered on. Subsequently, start the linear telescopic device 13 to extend. During the extension process, the opening and closing door panel 3 is driven to flip upward by the pulling force of the traction rope 9, thereby opening the opening and closing door panel 3. Place the detection tray 11 containing the beef sample flat on the support ring 10, and then start the linear telescopic device 13 to retract. The opening and closing door panel 3 loses the pulling force of the traction rope 9 and flips to the closed state under the action of gravity. Subsequently, each sensor inside the detection chamber operates, the lighting fixture 5 is turned on, the air inlet pipe 12 discharges air into the interior, and the sensors transmit the detected data to the display screen 4 through the circuit for the convenience of the staff to observe, thus completing the detection process.

[0046] The above description is a detailed description of the preferred and feasible embodiment of the present invention, but the embodiment is not intended to limit the scope of the patent application of the present invention. Any equivalent changes or modifications made under the technical spirit disclosed by the present invention shall fall within the scope of the patent covered by the present invention.
