DETAILED DESCRIPTION

[0034] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.

[0035] The first aspect of the present invention protects an emergency brake protection type livestock and poultry transport carriage, such as Figure 1-Figure 5 As shown, it includes: a frame 2 and a fixed plate 3, the fixed plates 3 have a plurality of pieces, all of which are fixedly connected to the frame 2, and the fixed plates 3 are slidably connected to the frame 2; sliding blocks 5, the number of sliding blocks 5 is the same as that of the fixed plates 3, and both are slidably connected to the frame 2, and the frame 2 is rotatably connected to guide wheels 6 with the same number as that of the sliding blocks 5, and a pull rope 7 is fixedly connected between the sliding blocks 5 and the adjacent extrusion plates 4, and the pull rope 7 is fitted with the adjacent guide wheel 6; buffer components, the number of buffer components is the same as that of the fixed plates 3, and they are respectively arranged on adjacent extrusion plates 4, for buffering the impact of livestock and poultry; reset components, the number of reset components is the same as that of the fixed plates 3, and both are arranged in the frame 2, for driving the adjacent extrusion plates 4 to reset; limiting components, the number of limiting components is the same as that of the fixed plates 3, and both are arranged in the frame 2, for limiting the adjacent sliding blocks 5.

[0036] The above-mentioned scheme proposes a solution for buffering the collision of livestock and poultry to avoid the collision of livestock and poultry under the action of inertia due to the sudden braking of the transport vehicle during transportation (mainly for livestock such as pigs, cattle and sheep); the frame 2 is installed on the existing transport vehicle, and the front and rear sides of the frame 2 are provided with fences, which can be opened to facilitate loading and unloading of livestock and poultry (the frame 2 is a special vehicle for existing livestock and poultry transportation, which can be switched as needed); a rubber pad is provided on the side of the extrusion plate 4 away from the fixed plate 3 to reduce damage to livestock and poultry. The number of extrusion plates 4 in the present invention is five; the surface of the sliding block 5 is made of smooth material, which is convenient for it to slide on the frame 2 to improve the accuracy of the detection result of the sudden braking of the transport vehicle. The number of sliding blocks 5 at each extrusion plate 4 in the present invention is two, and they are symmetrically distributed, so that the force on the extrusion plate 4 is more uniform, which is convenient for it to move; the guide wheel 6 is used to guide the pull rope 7; the pull rope 7 can be a steel wire rope (it can be made of a material that cannot be stretched).

[0037] The working process of the above scheme is as follows: when the vehicle frame 2 is used to transport livestock and poultry (taking the direction of travel to the left as an example), when the transport vehicle slowly decelerates, the livestock and poultry will shake slightly due to inertia, which will not endanger the safety of the livestock and poultry. At the same time, the limit assembly works to limit the sliding block 5 so that the sliding block 5 cannot move.

[0038] When the transport vehicle brakes suddenly, the speed of the transport vehicle drops rapidly, the two sliding blocks 5 break through the limit of the limit assembly, and move to the left under the action of inertia, the sliding block 5 pulls the pull rope 7, and the pull rope 7 pulls the extrusion plate 4 to move to the right. In this process, the livestock and poultry move to the left under the action of their own inertia, and the extrusion plate 4 moves relative to the livestock and poultry. When the extrusion plate 4 contacts the livestock and poultry, the extrusion plate 4 applies a reverse driving force to the livestock and poultry, cushions the impact of the livestock and poultry, slows down the movement of the livestock and poultry, and prevents the livestock and poultry from directly colliding with the frame 2 and causing injuries to the livestock and poultry.

[0039] Before the squeezing plate 4 contacts the livestock and poultry, the livestock and poultry trigger the buffer assembly to make the buffer assembly work, and the buffer assembly further buffers the livestock and poultry, further slowing down the movement speed of the livestock and poultry to ensure the safety of the livestock and poultry.

[0040] When the speed of the transport vehicle tends to be stable, the reset assembly works and drives the extrusion plate 4 to reset so as to work again.

[0041] Further, such as Figure 6 and Figure 7 As shown, the buffer assembly includes: a buffer plate 21 , which is slidably connected to the extrusion plate 4 ; and a first elastic member 22 , which is disposed between the buffer plate 21 and the extrusion plate 4 .

[0042] The above-mentioned scheme proposes a further buffering of the impact of livestock and poultry to strengthen the protection of livestock and poultry; the buffer plate 21 is made of rubber material, which can reduce the impact force on livestock and poultry and avoid hard impact with livestock and poultry to endanger the safety of livestock and poultry; the first elastic member 22 is a spring, which is used to drive the buffer plate 21 to reset and buffer the impact of livestock and poultry.

[0043] The working process of the above scheme is as follows: when the transport vehicle brakes suddenly, the livestock and poultry and the extrusion plate 4 will move relative to each other under the action of their own inertia. The extrusion plate 4 drives the buffer plate 21 to move through the first elastic member 22. When the buffer plate 21 contacts the livestock and poultry, the livestock and poultry squeeze the buffer plate 21 as the two move relative to each other. At the same time, the buffer plate 21 compresses the first elastic member 22. The impact of the livestock and poultry is buffered by the deformation of the first elastic member 22, so that the movement speed of the livestock and poultry is slowed down, thereby ensuring the safety of the livestock and poultry.

[0044] When the buffer plate 21 is separated from the livestock and poultry, the buffer plate 21 is restored under the action of the first elastic member 22 .

[0045] Further, such as Figure 7 and Figure 8 As shown, the reset assembly includes: a spur rack 31, which is fixed to the extrusion plate 4; a spur gear 32, which is rotatably connected to the frame 2, and the spur gear 32 is meshed with the spur rack 31; and a second elastic member 33, which is fixed between the spur gear 32 and the frame 2.

[0046] The above-mentioned scheme proposes a method for resetting the extrusion plate 4 so that the extrusion plate 4 can repeatedly buffer the impact of livestock and poultry; the spur rack 31 is located on the lower side of the middle part of the extrusion plate 4, and there is one spur rack 31 to ensure that the extrusion plate 4 is subjected to uniform force; the second elastic member 33 is a torsion spring, and the second elastic member 33 will twist and store force during the movement of the sliding block 5 under the action of inertia.

[0047] The working process of the above scheme is as follows: when the extrusion plate 4 moves to the right, the extrusion plate 4 drives the spur rack 31 thereon to move synchronously, the spur rack 31 drives the spur gear 32 to rotate, and the second elastic member 33 starts to accumulate force. During this process, the extrusion plate 4 buffers the impact of livestock and poultry.

[0048] When the driving speed of the transport vehicle tends to be stable, the moving speeds of the extrusion plate 4 and the livestock and poultry are slowed down. When the two stop moving relative to each other, the spur gear 32 stops rotating. Subsequently, the spur gear 32 rotates in the opposite direction under the action of the second elastic member 33, so that the spur rack 31 moves in the opposite direction. The spur rack 31 drives the extrusion plate 4 to move synchronously, so that the extrusion plate 4 is separated from the livestock and poultry, so that the extrusion plate 4 can buffer the impact of the livestock and poultry again.

[0049] Further, such as Figure 7 and Figure 8As shown, the limiting assembly includes: a first limiting column 41, which is slidably connected to the frame 2 and is limitedly matched with the sliding block 5; and a third elastic member 42, which is arranged between the frame 2 and the first limiting column 41.

[0050] The above-mentioned scheme of limiting the sliding block 5 can realize the detection of the speed change of the transport vehicle. When the transport vehicle brakes suddenly, the speed of the transport vehicle drops sharply, which will cause the sliding block 5 to move quickly under the action of its own inertia; the number of the first limiting column 41 is consistent with that of the sliding block 5, and the side of the first limiting column 41 close to the sliding block 5 is hemispherical, which can make the first limiting column 41 and the sliding block 5 move relative to each other; the third elastic member 42 is a spring, and the elastic coefficient of the third elastic member 42 is smaller than the elastic coefficient of the second elastic member 33, ensuring that the sliding block 5 can be moved and reset under the elastic force of the second elastic member 33, and then be limited with the first limiting column 41 again.

[0051] The working process of the above scheme is as follows: during the normal movement of the transport vehicle, when the speed of the transport vehicle slowly decreases, the livestock and poultry will shake slightly due to their own inertia, and the impact force generated by the sliding block 5 due to its own inertia is smaller than the limiting force of the first limiting column 41 on the sliding block 5, thereby making the sliding block 5 unable to move.

[0052] When the speed of the transport vehicle drops sharply, the impact force generated by the sliding block 5 under the action of its own inertia is greater than the limiting force of the first limiting column 41 on the sliding block 5, and the sliding block 5 begins to move and squeeze the first limiting column 41, and the third elastic member 42 is compressed until the sliding block 5 is separated from the first limiting column 41, and the first limiting column 41 is reset under the action of the third elastic member 42. At the same time, after the first limiting column 41 releases the obstruction to the sliding block 5, the sliding block 5 moves quickly and drives the extrusion plate 4 to move through the pull rope 7.

[0053] When the extrusion plate 4 moves in the reverse direction, the sliding block 5 slides in the reverse direction. When the sliding block 5 is again limitedly matched with the first limiting column 41, the sliding block 5 continues to move under the elastic force of the second elastic member 33 and squeezes the first limiting column 41 again. The third elastic member 42 is compressed again until the sliding block 5 is reset and the first limiting column 41 clamps the sliding block 5 again.

[0054] Further, such as Figure 7-Figure 9 As shown, it also includes: friction blocks 51, the number of friction blocks 51 is the same as that of the fixed plate 3, and they are respectively slidably connected to the extrusion plate 4, and the friction blocks 51 are extruded and matched with the frame 2; trigger components, the number of trigger components is the same as that of the extrusion plate 4, and they are respectively used to drive the adjacent friction blocks 51 to move.

[0055] The above-mentioned scheme for controlling the moving speed of the extrusion plate 4 is proposed. When large livestock and poultry are transported, the heavier the weight, the greater the inertia. When the livestock and poultry come into contact with the extrusion plate 4, when the impact force of the livestock and poultry is greater than the blocking force of the extrusion plate 4, the livestock and poultry will drive the extrusion plate 4 to move synchronously, and at this time the livestock and poultry will collide with the frame 2; the number of friction blocks 51 and sliding blocks 5 is the same, and at the same time, their contact surfaces with the frame 2 are all made of high-friction materials such as rubber to increase the friction between the two.

[0056] The working process of the above scheme is as follows: when livestock and poultry come into contact with the buffer plate 21 and squeeze each other, the buffer plate 21 causes the trigger component to start working, and the trigger component squeezes the friction block 51, so that the friction block 51 is close to the frame 2, thereby gradually increasing the friction force between the friction block 51 and the frame 2, generating resistance to the movement of the squeezing plate 4, and slowing down the movement speed of the squeezing plate 4. The greater the relative movement distance between the buffer plate 21 and the squeezing plate 4, the greater the squeezing force of the friction block 51 on the frame 2, and the greater the movement resistance of the squeezing plate 4.

[0057] In the process where large livestock and poultry directly push the extrusion plate 4 to reset due to inertia, the extrusion plate 4 slowly resets under the action of the friction block 51, making it impossible for the large livestock and poultry to directly push the extrusion plate 4 to reset, thereby further buffering the impact force of the large livestock and poultry through the slow movement of the extrusion plate 4. In this process, the friction block 51 is only used to increase the resistance to the movement of the extrusion plate 4, and will not directly jam the extrusion plate 4.

[0058] When the squeezing plate 4 is separated from the livestock and poultry, the buffer plate 21 is reset and stops squeezing the friction block 51 through the trigger assembly, so that the friction block 51 no longer squeezes the frame 2.

[0059] Further, such as Figure 7-Figure 9 As shown, the trigger assembly includes: a trigger rod 61, which is slidably connected to the extrusion plate 4 and is extruded and matched with the buffer plate 21; an extrusion block 62, which is fixed to the side of the trigger rod 61 away from the buffer plate 21, and is extruded and matched with the friction block 51; and a fourth elastic member 63, which is arranged between the extrusion block 62 and the extrusion plate 4.

[0060] The above-mentioned scheme proposes a method for driving the friction block 51 to move, which can control the squeezing force of the friction block 51 on the frame 2; the upper side of the trigger rod 61 is hemispherical, and a protrusion is provided on the side of the buffer plate 21 close to the trigger rod 61, and the protrusion has an inclined surface, and the trigger rod 61 is squeezed by the inclined surface of the protrusion on the buffer plate 21 to move the trigger rod 61; the cross-section of the squeezing block 62 is triangular, so as to control the synchronous movement of two adjacent friction blocks 51; the fourth elastic member 63 is a tension spring, which is used to drive the squeezing block 62 to reset.

[0061] The working process of the above scheme is as follows: when livestock and poultry contact and squeeze each other with the buffer plate 21, the buffer plate 21 squeezes the trigger rod 61, causing the trigger rod 61 to move downward, and the trigger rod 61 pushes the squeezing block 62 to move, the fourth elastic member 63 is stretched, and the squeezing block 62 squeezes the friction block 51, causing the friction block 51 to gradually approach the frame 2 and gradually squeeze the frame 2, thereby increasing the friction between the friction block 51 and the frame 2, thereby generating resistance to the movement of the squeezing plate 4.

[0062] When the livestock and poultry are separated from the buffer plate 21 , the buffer plate 21 is reset and the extrusion of the trigger rod 61 is released. The extrusion block 62 is reset under the action of the fourth elastic member 63 and drives the trigger rod 61 to reset. At the same time, the extrusion block 62 no longer squeezes the friction block 51 .

[0063] Further, such as Figure 6 , Fig.10 and Fig.11 As shown, it also includes: an adjusting mechanism, the number of the adjusting mechanism is the same as that of the fixing plate 3, and both are arranged in the frame 2, and are used to adjust the position of the extrusion plate 4, the adjusting mechanism includes: a transmission rod 71, the transmission rod 71 is rotatably connected in the frame 2; a force rod 72, the force rod 72 is splined to the transmission rod 71, and a fifth elastic member 73 is arranged between the two, and the force rod 72 is limitedly slidably connected to the frame 2; a sliding plate 74, the sliding plate 74 is slidably connected to the frame 2, the sliding plate 74 is connected to the transmission rod 71 through a gear rack transmission, the sliding plate 74 is rotatably connected to the extrusion wheel 75, and the extrusion wheel 75 is extruded and matched with the pull rope 7.

[0064] The above-mentioned scheme for adjusting the initial position of the extrusion plate 4 is proposed, so that the position of the extrusion plate 4 can adapt to livestock and poultry of different sizes, ensuring that livestock and poultry of different sizes can be buffered; the force rod 72 is provided with a hexagonal hole for easy rotation operation; the fifth elastic member 73 is a spring for driving the force rod 72 to reset; the frame 2 is provided with an annular groove and a spline groove ( Fig.12 As shown in the figure, a spline is arranged on the outer side of the force application rod 72. In the initial state, the spline of the force application rod 72 is located in the spline groove of the frame 2. At this time, the two cannot rotate relative to each other. When the spline of the force application rod 72 is located in the annular groove of the frame 2, the two can rotate relative to each other.

[0065] The working process of the above scheme is as follows: when transporting small livestock and poultry, the position of the extrusion plate 4 is first adjusted. The specific steps are as follows: insert the hexagonal wrench into the hexagonal hole of the force rod 72 and press the hexagonal wrench. The force rod 72 moves backward and the fifth elastic member 73 is compressed. At this time, the spline of the force rod 72 moves from the spline groove of the frame 2 to the annular groove of the frame 2, and then the hexagonal wrench is rotated. The hexagonal wrench drives the force rod 72 to rotate, thereby driving the transmission rod 71 to rotate. The transmission rod 71 drives the sliding plate 74 to move upward through the gear rack, thereby driving the extrusion wheel 75 to move. The extrusion wheel 75 squeezes the pull rope 7 to bend the pull rope 7. At this time, since the sliding block 5 cannot move, the pull rope 7 pulls the extrusion plate 4 to move to the right, and the second elastic member 33 accumulates force to adjust the distance between the extrusion plate 4 and the livestock and poultry, so that the position of the extrusion plate 4 can adapt to livestock and poultry of different sizes.

[0066] When the position of the extrusion plate 4 is adjusted, stop squeezing the hexagonal wrench. At this time, the force rod 72 is reset under the elastic action of the fifth elastic member 73. During this process, the position of the force rod 72 is fine-tuned by the hexagonal wrench so that the spline of the force rod 72 is inserted into the spline groove of the frame 2 again, and then the hexagonal wrench is taken out.

[0067] When transporting large livestock and poultry, the above process is followed and the transmission rod 71 is rotated in the reverse direction, so that the squeezing wheel 75 stops squeezing the pull rope 7, and the squeezing plate 4 is reset under the action of the second elastic member 33.

[0068] The second aspect of the present invention protects a transport vehicle, which uses the above-mentioned emergency brake protection type livestock and poultry transport vehicle, such as Figure 3 , Figure 4 , Fig.12 and Fig.13 As shown, it includes: a vehicle body 1; a support rod 81, which is fixedly connected to the vehicle body 1; a second limiting column 82, which is fixedly connected to the support rod 81, and the second limiting column 82 is limitedly matched with the frame 2, and the frame 2 is slidably connected to the vehicle body 1.

[0069] The above-mentioned scheme for buffering the impact of the frame 2 can further ensure the safety of livestock and poultry in the frame 2; two limiting holes are provided on the frame 2, and the limiting holes of the frame 2 are limitedly matched with the second limiting column 82; the second limiting column 82 is made of hard rubber. During the normal driving of the vehicle body 1, the support rod 81 is inserted into the limiting hole of the frame 2 through the second limiting column 82, thereby completing the fixation of the frame 2, and then the frame 2 and the vehicle body 1 form a whole.

[0070] The working process of the above scheme is as follows: during the normal driving of the vehicle body 1, when encountering an emergency brake, its speed will drop sharply, and the frame 2 will tend to move to the left under the action of its own inertia. At this time, the frame 2 squeezes the second limiting column 82. When the impact force of the frame 2 is greater than the force required for the deformation of the second limiting column 82, the second limiting column 82 is deformed and contracts, and the limiting hole on the left side of the frame 2 is separated from the second limiting column 82. Then the frame 2 drives all parts and livestock and poultry thereon to move to the left until the limiting hole on the right side of the frame 2 is aligned with the second limiting column 82. The second limiting column 82 is inserted into the limiting hole on the right side of the frame 2. By moving the frame 2 a certain distance (relative to the vehicle body 1), its impact force is buffered, the movement of livestock and poultry is slowed down, and the risk of livestock and poultry collision is reduced to ensure the safety of livestock and poultry.

[0071] Further, such as Figure 4 , Fig.10 and Fig.13 As shown, it also includes: a pushing frame 91, the number of the pushing frame 91 is the same as that of the fixing plate 3, both are slidably connected to the frame 2, and are pressed and matched with the adjacent friction block 51, and the support rod 81 is pressed and matched with the pushing frame 91.

[0072] The above-mentioned scheme proposes a multiple buffering for livestock and poultry, which can gradually slow down the movement speed of livestock and poultry; an inclined block is provided on the lower side of the pushing frame 91; the support rod 81 is provided with a triangular groove, and the pushing frame 91 is squeezed by the inclined surface thereon, so that the pushing frame 91 moves.

[0073] The working process of the above scheme is as follows: in the process of relative movement between the extrusion plate 4 and the livestock and poultry, emergency braking has been performed, the friction block 51 has begun to play a role, the movement speed of the extrusion plate 4 is slow, the extrusion plate 4 gradually contacts with the livestock and poultry, and buffers the impact force of the livestock and poultry. In this process, the frame 2 and the vehicle body 1 move relative to each other, the frame 2 and the support rod 81 move relative to each other, the frame 2 drives the pushing frame 91 thereon to move, the pushing frame 91 moves along the inclined surface of the triangular groove on the support rod 81, and moves upward under the extrusion action of the inclined surface. In the process of the pushing frame 91 moving upward, when the pushing frame 91 contacts the friction block 51, as the pushing frame 91 moves, the pushing frame 91 begins to squeeze the friction block 51, and the friction block 51 moves and moves away from the frame 2, thereby reducing the friction between the friction block 51 and the frame 2.

[0074] When the friction block 51 is moving, the friction block 51 drives the buffer plate 21 to move through the squeezing block 62 and the trigger rod 61, so that the buffer plate 21 applies a reverse force to the livestock and poultry, further slowing down the movement speed of the livestock and poultry.

[0075] When the friction block 51 is separated from the frame 2, the movement resistance of the extrusion plate 4 disappears, and the livestock and poultry pushes the extrusion plate 4 to move to the left, and the extrusion plate 4 drives the friction block 51 to move until the friction block 51 is separated from the pushing frame 91. At this time, the livestock and poultry continue to squeeze the buffer plate 21, and the buffer plate 21 drives the friction block 51 to move and contact the frame 2 again, so that the movement resistance of the extrusion plate 4 is increased again, thereby strengthening the buffering of the impact force of the livestock and poultry. The pushing frame 91 controls the movement resistance of the extrusion plate 4, so that the extrusion plate 4 is adjusted from a large movement resistance to a small movement resistance and then to a large movement resistance, thereby achieving a step-by-step control of the livestock and poultry. Stage buffering, that is, when the extrusion plate 4 contacts with the livestock and poultry, the livestock and poultry are buffered for the first time (at this time, the movement resistance is large, so that the movement speed of the livestock and poultry decreases rapidly), and then the extrusion plate 4 moves with the livestock and poultry (at this time, the movement resistance is small, so that the movement speed of the livestock and poultry decreases slowly), and finally the extrusion plate 4 buffers the livestock and poultry again (at this time, the movement resistance is large, so that the speed of the livestock and poultry decreases rapidly). By buffering the speed of the livestock and poultry in the above-mentioned stages, it is prevented that when the extrusion plate 4 initially buffers the impact force of the livestock and poultry, the extrusion plate 4 forms a certain impact force on the livestock and poultry and endangers the safety of the livestock and poultry, thereby ensuring the safety of the livestock and poultry.
