[0016] Compared with the prior art, the present invention provides a poultry loading and conveying device, which has the following beneficial effects:

[0017] 1. The present invention provides a poultry loading and conveying device. When the poultry is conveyed by a conveyor belt, the weight distribution of the poultry during the conveying process is improved by an adjusting mechanism, so as to avoid uneven wear of the conveyor belt, thereby reducing the deviation of the conveyor belt during operation, preventing the poultry from falling from the conveyor belt, and improving the operation efficiency and safety.

[0018] 2. The present invention sets a downward pressing component. When the length of the conveyor belt needs to be shortened, the second sliding frames on both sides are pulled by the hydraulic rod to move toward the supporting frame. As the conveyor belt shortens, under the action of the first spring, the first sliding frame slides downward along the first fixed axis, and the first auxiliary roller connected by rotation through the inner wall of the first sliding frame presses down the loose area at the bottom of the conveyor belt, so that the conveyor belt can always remain taut, effectively reducing the probability of deviation due to loose conveyor belt.

[0019] 3. The present invention provides an adjustment mechanism. When the poultry is conveyed, the hydraulic rod pushes the second sliding frame to adjust to a suitable length. The motor drives the driving roller to operate, and the conveyor belt is driven to rotate by the driving roller. During the operation of the conveyor belt, the second auxiliary roller provides auxiliary rolling action. At the same time, the auxiliary components support the outer walls of both sides of the conveyor belt, thereby effectively avoiding the deviation of the conveyor belt when conveying poultry, and ensuring the stability and smoothness of the conveying process.

[0020] 4. The present invention sets an auxiliary component. During the operation of the conveyor belt, when the third auxiliary roller is squeezed by the conveyor belt, the third sliding frame will be squeezed through the rotating frame. The rotating frame slides on the inner wall of the third sliding block with the help of the third fixed shaft. The third spring is used to absorb the vibration generated by the third sliding frame, thereby effectively reducing the excessive friction of the third auxiliary roller on the conveyor belt and reducing the wear of the outer surfaces of both sides of the conveyor belt, thereby extending the service life of the conveyor belt in poultry conveying operations.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Example 1: See Figure 1-Figure 4 The present invention provides a technical solution: a poultry loading and conveying device, including a supporting mechanism 1, the supporting mechanism 1 includes a supporting frame 101, the bottom outer wall of the supporting frame 101 is fixedly connected with a supporting foot 102, the outer surface of the supporting frame 101 is provided with a first sliding groove 103, the inner wall of the supporting frame 101 is fixedly connected with a hydraulic rod 104, the outer surface of one side of the supporting frame 101 close to the supporting foot 102 is fixedly connected with a first fixed shaft 105, the bottom of the supporting frame 101 is provided with a pressing component 106, and also includes:

[0034] The adjusting mechanism 2 comprises a second sliding frame 201 fixedly connected to the output end of the hydraulic rod 104, a second sliding groove 202 is provided on the outer surface of the second sliding frame 201, a second auxiliary roller 203 is rotatably connected to the inner wall of the second sliding frame 201 through a rotating shaft, a second fixed shaft 207 is fixedly connected to the outer wall of one end of the second sliding frame 201 away from the second sliding groove 202, a fixed block 204 is fixedly connected to the outer wall of the side of the second sliding frame 201 close to the second auxiliary roller 203, a motor 205 is fixedly connected to the outer wall of the side of the second sliding frame 201 away from the hydraulic rod 104, an output end of the motor 205 passes through the second sliding frame 201 and is fixedly connected to a driving roller 206, a conveyor belt 3 is rotatably connected to the outer surface of the driving roller 206, and the conveyor belt 3 is provided to prevent the center of gravity of the poultry from shifting during transportation. The structure is designed with both sides higher than the central area. The interior of the second sliding frame 201 is provided with an auxiliary component 208. The second auxiliary roller 203 is used to assist the rotation of the conveyor belt 3, and the driving roller 206 is used to drive the rotation of the conveyor belt 3. When starting the poultry conveying operation, first operate the hydraulic rod 104 to push the second sliding frame 201 to adjust to a suitable position, determine that the length is appropriate, and then start the motor 205. The motor 205 drives the driving roller 206, and the driving roller 206 drives the conveyor belt 3 to rotate. During the operation of the conveyor belt 3, the second auxiliary roller 203 cooperates to assist the conveyor belt 3 to roll smoothly. At the same time, the auxiliary component 208 plays a role in supporting the outer wall of the conveyor belt 3 from both sides, and comprehensively guarantees that the conveyor belt 3 will not deviate when conveying poultry, thereby ensuring that the conveying work is stable and efficient.

[0035] The pressing assembly 106 includes a first sliding frame 1061 slidably connected to the first fixed shaft 105, the inner wall of the first sliding frame 1061 is rotatably connected to the first auxiliary roller 1062 through a rotating shaft, the bottom outer wall of the first sliding frame 1061 is fixedly connected to a first spring 1063, the end of the first spring 1063 away from the first sliding frame 1061 is fixedly connected to the bottom of the first fixed shaft 105, the first sliding frame 1061 drives the first auxiliary roller 1062 to slide along the outer surface of the first fixed shaft 105, if the length of the conveyor belt 3 is to be shortened, the hydraulic rod 104 can be started to pull the second sliding frames 201 on both sides to make it Move toward the direction of the support frame 101, as the conveyor belt 3 gradually shortens, under the elastic force of the first spring 1063, the first sliding frame 1061 will slide downward along the first fixed axis 105, and the inner wall of the first sliding frame 1061 is rotatably connected to the first auxiliary roller 1062. During the sliding downward movement of the first sliding frame 1061, the first auxiliary roller 1062 will apply tension to the slack area at the bottom of the conveyor belt 3 to stretch it. In this way, no matter what length the conveyor belt 3 is transported, it can always maintain a taut state, effectively reducing the deviation phenomenon caused by the relaxation of the conveyor belt 3, thereby ensuring the stability of the conveying process.

[0036] The inner wall of the first sliding frame 1061 is rotatably connected to the first rotating rod 1064 via a rotating shaft, and the first rotating rod 1064 is rotatably connected to the first sliding block 1065 at one end away from the first sliding frame 1061. The first sliding block 1065 is slidably connected to the inner wall of the first sliding groove 103. During the downward sliding of the first sliding frame 1061, the first sliding frame 1061 uses the first rotating rod 1064 to pull the first sliding block 1065 to slide on the inner wall of the first sliding groove 103, thereby effectively enhancing the stability of the first sliding frame 1061 during movement, and the first sliding groove 103 serves to limit the sliding distance of the first sliding block 1065.

[0037] Example 2: Please refer to Figure 5-Figure 8 On the basis of the first embodiment, the present invention provides a technical solution: the auxiliary component 208 includes a second sliding block 2081 slidably connected to the second fixed shaft 207, the bottom outer wall of the second sliding block 2081 is fixedly connected to a second spring 2082, one end of the second spring 2082 away from the second sliding block 2081 is fixedly connected to the bottom of the second fixed shaft 207, the outer wall of the second sliding block 2081 is rotatably connected to a second rotating rod 2083 through a rotating shaft, and one end of the second rotating rod 2083 away from the second sliding block 2081 is rotatably connected to a third sliding block 2084 through a rotating shaft, when it is necessary to When the two sides of the conveyor belt 3 are adjusted, the second spring 2082 will play a role, and the tension it generates will cause the second sliding block 2081 to move downward along the second fixed axis 207. During the downward movement of the second sliding block 2081, it will drive the third sliding block 2084 through the second rotating rod 2083 to slide on the inner wall of the second sliding groove 202. As the third sliding block 2084 slides, the third auxiliary roller 2088 connected to it will apply an extrusion force to both sides of the conveyor belt 3, thereby effectively avoiding the conveyor belt 3 from deflecting during the conveying process and ensuring the stable operation of the conveyor belt 3.

[0038] A third sliding frame 2085 is arranged on the top of the third sliding block 2084. The inner wall of the end of the third sliding frame 2085 away from the third sliding block 2084 is rotatably connected to a rotating frame 2089 via a rotating shaft. The end of the rotating frame 2089 away from the third sliding frame 2085 is rotatably connected to the fixed block 204. The inner wall of the rotating frame 2089 is rotatably connected to a third auxiliary roller 2088 via a rotating shaft. During the operation of the conveyor belt 3, the conveyor belt 3 will squeeze the third auxiliary roller 2088, thereby generating pressure on the third sliding frame 2085. After the third auxiliary roller 2088 is squeezed, The rotating frame 2089 is caused to rotate at a certain angle. When the rotating frame 2089 rotates, it will push the third sliding frame 2085, driving the third sliding block 2084 to move. During the movement of the third sliding block 2084, the second sliding block 2081 is caused to slide along the outer surface of the second fixed shaft 207 through the second rotating rod 2083, thereby ensuring that the inclination angles of the third auxiliary rollers 2088 on both sides of the conveyor belt 3 remain consistent, thereby effectively avoiding the problem of increased wear caused by the shift of the center of gravity of the conveyor belt 3 when conveying poultry, and ensuring the stable and long-lasting operation of the conveyor belt 3.

[0039] A third fixed shaft 2086 is fixedly connected to the outer wall of one side of the third sliding frame 2085 close to the third sliding block 2084. The third fixed shaft 2086 penetrates the third sliding block 2084 and is fixedly connected to a third spring 2087. One end of the third spring 2087 close to the third sliding frame 2085 is fixedly connected to the third sliding block 2084. During the operation of the conveyor belt 3, once the third auxiliary roller 2088 is squeezed by the conveyor belt 3, it will apply pressure to the third sliding frame 2085 with the help of the rotating frame 2089. The rotating frame 2089 relies on the third fixed shaft 2086 to slide on the inner wall of the third sliding block 2084. At the same time, the third spring 2087 begins to play a role. It can absorb the vibration of the third sliding frame 2085 caused by the force, thereby effectively reducing the excessive friction of the third auxiliary roller 2088 on the conveyor belt 3, and reducing the wear degree of the outer surfaces on both sides of the conveyor belt 3, thereby increasing the service life of the conveyor belt 3 during the poultry conveying operation, and ensuring the long-term and stable conveying work.
