DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Example 1: This example provides an intelligent transport device for agricultural products. Figures 1 to 7 Specifically, it includes an open transport box 100. The open transport box 100 serves as the main body of the entire equipment, provides storage space for agricultural products, and provides an installation base for other components. Its open design facilitates the loading and unloading operations of agricultural products. Three pairs of equally spaced first rollers 101 are rotatably provided on both sides of the interior of the open transport box 100. The middle part of each first roller 101 is sleeved with a concentrically fixed first roller 102. Each first roller 102 is fixed with a flip-top partition 103. The first roller 101 is the core axis body for the swing of the flip-top partition 103. The first roller 101 drives the first roller 102 and the flip-top partition 103 to move synchronously through its own rotation. The flip-top partition 103 is closed and unfolded by swinging, and is used to isolate the agricultural products in the open transport box 100 in layers to prevent different layers of agricultural products from squeezing each other.

[0034] A fixed plate 200 is fixed on the front of the open transport box 100. The fixed plate 200 is used to install transmission components such as a fixed shaft 109 to provide stable support for related components. A pair of motors 201 are fixedly installed at the two corners of the top surface of the fixed plate 200. The motor shaft end of each motor 201 is fixedly provided with a fixed shaft 109. Three equidistantly distributed thickened turntables 110 are fixedly sleeved on each fixed shaft 109. Each thickened turntable 110 is connected to the first roller 101 on the corresponding side through a limiting mechanism. The fixed shaft 109 is an axis that drives the thickened turntable 110 to rotate, providing rotation support and power for the thickened turntable 110. The thickened turntable 110 controls the position of the limit pin 107 by its own rotation, and then controls the rotation of the first roller 101 to realize the state switching of the flip partition 103;

[0035] A pair of symmetrically distributed second rollers 300 are rotatably mounted on both sides of the top opening of the open transport box 100. A concentrically fixed second roller 301 is sleeved on the middle of each second roller 300. A flip cover baffle 302 is fixed to each second roller 301. The second roller 300 is the core axis for the swing of the flip cover baffle 302, driving the second roller 301 and the flip cover baffle 302 to move synchronously. The flip cover baffle 302 is closed and opened by swinging, thereby covering or opening the top opening of the open transport box 100, protecting the agricultural products on the top and facilitating loading and unloading.

[0036] A pair of symmetrically distributed fixed couplings 312 are rotatably provided on the upper middle part of the back side of the open transport box 100. A triangular connecting plate 304 is fixed to the outer end of each fixed coupling 312. Each triangular connecting plate 304 is connected to the second roller shaft 300 on the corresponding side through a hinge mechanism. The triangular connecting plate 304 is connected to the second roller shaft 300 through a hinge mechanism, and is hinged to the long connecting rod 306 and the short connecting rod 307 at the same time, which plays the role of transmitting power and converting the direction of movement, and converting the movement of the connecting rod into the rotation of the second roller shaft 300.

[0037] In the specific implementation process, Figure 3 and Figure 4 As shown, a pair of symmetrically distributed fixing ears 108 are fixed to the upper middle portion of the front of the open transport box 100. The top end of each fixing shaft 109 is rotatably inserted into the front end of the fixing ear 108 on the corresponding side. The fixing ears 108 provide rotational support for the top end of the fixing shaft 109, ensuring the stability of the fixing shaft 109 during rotation.

[0038] The front end of each first roller 101 rotates through the open transport box 100 and extends forward. A vertically distributed fixed swing arm 104 is fixed to the front end of each first roller 101. A counterweight 105 is fixed to the outer end of each fixed swing arm 104. The fixed swing arm 104 cooperates with the counterweight 105 to drive the first roller 101, the first roller 102 and the flip cover partition 103 to swing downward by gravity.

[0039] The limiting mechanism includes a limiting swing arm 106 and a limiting pin 107. The front end of each first roller 101 extends forward and is fixed with a limiting swing arm 106. The outer end of each limiting swing arm 106 is fixed with a limiting pin 107. A limiting notch 111 is provided on the outer surface of each thickened turntable 110. Each limiting pin 107 slides against the corresponding limiting notch 111. The limiting pin 107 slides against the limiting notch 111 of the thickened turntable 110 or the top surface of the thickened turntable 110. By cooperating with the limiting notch 111, the rotation angle of the first roller 101 is limited, thereby realizing the positioning of the flip cover partition 103.

[0040] One side of the limiting notch 111 is at a forty-five-degree bevel, and the other side is at a ninety-degree right angle. The opening angle of the pair of limiting notches 111 at the top is thirty degrees, the opening angle of the pair of limiting notches 111 at the middle is one hundred and eighty degrees, and the opening angle of the pair of limiting notches 111 at the bottom is three hundred and thirty degrees. The opening angles of the limiting notches 111 at different positions are different, and the two sides are at a forty-five-degree bevel and a ninety-degree right angle respectively, which cooperate with the limiting pin 107 to achieve precise limiting of the rotation of the first roller 101.

[0041] It should be noted that in this embodiment, a single-chip microcomputer 202 is fixedly installed in the middle of the fixed plate 200, and a power supply 204 is fixedly installed behind the single-chip microcomputer 202. An H-bridge driver module 203 is fixedly installed on the single-chip microcomputer 202. The single-chip microcomputer 202 transmits a control signal to the H-bridge driver module 203. The power supply 204 supplies power to the motor 201, the H-bridge driver module 203, and the electric telescopic cylinder 311. After receiving the control signal, the H-bridge driver module 203 outputs a drive signal to control the pair of motors 201 to achieve forward and reverse rotation.

[0042] The single-chip microcomputer 202 sends a PWM control signal to the H-bridge driver module 203. At the same time, the power supply 204 provides the operating voltage for the H-bridge driver module 203 and the motor 201. The H-bridge driver module 203 configures the conduction state of the internal MOSFET bridge arm according to the received control signal, and realizes forward and reverse control by changing the voltage polarity across the motor 201.

[0043] When the single chip microcomputer 202 sends a positive control signal, the H-bridge driving module 203 outputs a positive voltage to drive the motor 201 to rotate clockwise, driving the fixed shaft 109 to rotate clockwise synchronously;

[0044] When the single-chip microcomputer 202 sends a reverse control signal, the H-bridge driver module 203 switches the output voltage polarity, drives the motor 201 to rotate counterclockwise, and drives the fixed shaft 109 to rotate counterclockwise synchronously; by adjusting the duty cycle of the PWM signal, it is possible to achieve both forward and reverse rotation of the pair of motors 201 and precise control of the speed of the motors 201.

[0045] The working principle of this embodiment is as follows: In the initial state, the limiting pins 107 all slide against the top surface of the thickened turntable 110 on the corresponding side. At this time, the pair of flip cover baffles 302 and the three pairs of flip cover partitions 103 are all in the unfolded state, ready for the agricultural products to be packed;

[0046] During the agricultural product packing stage, the operation process is gradually advanced according to the logic of layered storage: first, some agricultural products are loaded into the bottom of the open transport box 100, and then a pair of motors 201 are synchronously driven to rotate forward and reverse; the fixed shaft 109 drives the three thickened turntables 110 on the same side to rotate synchronously. During this process, the limit pin 107 at the bottom slides along the top surface of the corresponding thickened turntable 110 and finally falls into the corresponding limit notch 111, while the pair of limit pins 107 at the top and middle continue to slide along the top surface of the corresponding thickened turntable 110; under the action of the gravity of the bottom counterweight block 105 and the fixed swing arm 104, the bottom first roller 101, the first roller 102 and the flip cover partition 103 are driven to swing downward, so that the bottom pair of flip cover partitions 103 complete the closing action;

[0047] Next, some agricultural products are placed on the bottom pair of flip-cover partitions 103, and the pair of motors 201 are synchronously driven again to rotate forward and reverse; the fixed shaft 109 drives the three thickened turntables 110 on the same side to rotate synchronously. At this time, the bottom limit pin 107 slides along the corresponding limit notch 111, and the middle limit pin 107 slides along the top surface of the corresponding thickened turntable 110 and falls into the corresponding limit notch 111. The top limit pin 107 still keeps sliding on the top surface of the thickened turntable 110; under the action of the gravity of the middle counterweight block 105 and the fixed swing arm 104, the middle first roller 101, the first roller 102 and the flip-cover partition 103 swing downward, realizing the closing of the middle pair of flip-cover partitions 103;

[0048] Afterwards, some agricultural products are placed on the middle pair of flip-cover partitions 103, and the pair of motors 201 are synchronously driven for a third time to rotate forward and reverse. The fixed shaft 109 drives the three thickened turntables 110 on the same side to rotate synchronously. At this time, the bottom and middle limit pins 107 slide along the corresponding limit notches 111, and the top limit pin 107 slides along the top surface of the corresponding thickened turntable 110 and falls into the corresponding limit notch 111. Under the action of the gravity of the top counterweight block 105 and the fixed swing arm 104, the top first roller 101, the first roller 102 and the flip-cover partition 103 swing downward, completing the closing of the top pair of flip-cover partitions 103.

[0049] Finally, the remaining agricultural products are placed on the top pair of flip-top partitions 103, which are driven by the hinge mechanism and the triangular connecting plate 304 to swing the second roller 300, the second roller 301 and the flip-top baffle 302 downward, so that the pair of flip-top baffles 302 are closed, thereby realizing the layered storage of agricultural products in the open transport box 100 and effectively preventing the agricultural products from being damaged by being squeezed against each other.

[0050] During the agricultural product unloading stage, the operation process is carried out layer by layer in the reverse order: first, the hinge mechanism drives the triangular connecting plate 304 to drive the second roller 300, the second roller 301 and the flip cover baffle 302 to swing upward, so that the pair of flip cover baffles 302 are unfolded;

[0051] After the agricultural products on the top pair of flip-cover partitions 103 are taken out, the pair of motors 201 are synchronously driven to rotate forward and reverse; the fixed shaft 109 drives the three thickened turntables 110 on the same side to rotate synchronously. At this time, the bottom and middle limit pins 107 slide along the corresponding limit notches 111, and the top limit pin 107 slides along the limit notch 111 to the top surface of the thickened turntable 110. The limit swing arm 106 drives the top first roller 101, fixed swing arm 104, counterweight 105, first roller 102 and flip-cover partition 103 to swing upward, so that the top pair of flip-cover partitions 103 are unfolded;

[0052] After the agricultural products on the middle pair of flip-cover partitions 103 are taken out, the pair of motors 201 are synchronously driven again to rotate forward and reverse; the fixed shaft 109 drives the three thickened turntables 110 on the same side to rotate synchronously. At this time, the uppermost limit pin 107 slides along the top surface of the thickened turntable 110, and the lowermost limit pin 107 slides along the corresponding limit notch 111. The middle limit pin 107 then slides along the corresponding limit notch 111 to the top surface of the thickened turntable 110, and the middle first roller 101, fixed swing arm 104, counterweight 105, first roller 102 and flip-cover partition 103 are driven to swing upward through the limit swing arm 106, so that the middle pair of flip-cover partitions 103 are unfolded;

[0053] After taking out the agricultural products on the bottom pair of flip-cover partitions 103, the pair of motors 201 are synchronously driven for the third time to rotate forward and reverse; the fixed shaft 109 drives the three thickened turntables 110 on the same side to rotate synchronously. At this time, the uppermost and middle limit pins 107 slide along the top surfaces of the corresponding thickened turntables 110, and the lowermost limit pin 107 slides along the corresponding limit notch 111 to the top surface of the thickened turntable 110, and the lowermost first roller 101, fixed swing arm 104, counterweight 105, first roller 102 and flip-cover partition 103 are driven to swing upward through the limit swing arm 106, so that the bottom pair of flip-cover partitions 103 are unfolded, and finally the remaining agricultural products at the bottom of the open transport box 100 can be taken out.

[0054] Example 2: Based on Example 1, a drive mechanism consisting of an articulated mechanism, a central shaft 308, and an electric telescopic cylinder 311 is added to clarify the automatic drive mode of the flip cover baffle 302, solving the problems of the unclear articulated mechanism drive mode and the inconvenience of manual operation of the flip cover baffle 302 in Example 1, further improving the automation level and operational convenience of the equipment. Also included:

[0055] In the specific implementation process, Figure 6 and Figure 7 As shown, the hinge mechanism includes an L-shaped swing arm 303 and an articulated link 305. The rear end of each second roller shaft 300 passes through the open transport box 100 and extends rearward. The rear end of each second roller shaft 300 is fixedly provided with an L-shaped swing arm 303. The top end of each triangular connecting plate 304 is provided with a movably hinged articulated link 305. The top end of each articulated link 305 is movably hinged to the L-shaped swing arm 303 on the corresponding side. The articulated link 305 is a motion transmission component between the triangular connecting plate 304 and the L-shaped swing arm 303, converting the swing of the triangular connecting plate 304 into the swing of the L-shaped swing arm 303.

[0056] A central shaft 308 is provided on the back of the open transport box 100 for rotation. A central swing arm 309 is fixed to the rear end of the central shaft 308. A long connecting rod 306 and a short connecting rod 307 are respectively hinged at both ends of the central swing arm 309. The outer ends of the long connecting rod 306 and the short connecting rod 307 are movably hinged to the middle of the triangular connecting plate 304 on the corresponding side. The central swing arm 309 rotates under the drive of the electric telescopic cylinder 311, transmitting power to the long connecting rod 306 and the short connecting rod 307. The long connecting rod 306 and the short connecting rod 307 are used to transmit the movement of the central swing arm 309, driving the triangular connecting plate 304 to swing.

[0057] A T-shaped seat 310 is fixedly provided on the back of the open transport box 100, and a movable hinged electric telescopic cylinder 311 is provided on the T-shaped seat 310. The end of the telescopic rod of the electric telescopic cylinder 311 is coaxially hinged with the hinge point of the long connecting rod 306 and the central swing arm 309. The electric telescopic cylinder 311 is the power source for the swinging of the flip cover baffle 302, and the central swing arm 309 is driven to rotate by the extension and contraction of the telescopic rod.

[0058] The working principle of this embodiment is as follows: when the telescopic rod of the electric telescopic cylinder 311 is extended, the central swing arm 309 is driven to rotate along the central axis 308 under the action of the hinge. The two ends of the central swing arm 309 respectively drive the long connecting rod 306 and the short connecting rod 307 to expand to both sides; the long connecting rod 306 and the short connecting rod 307 drive the triangular connecting plate 304 on the corresponding side to swing upward along the fixed coupling 312. The triangular connecting plate 304 then drives the L-shaped swing arm 303, the second roller 300, the second roller 301 and the flip cover baffle 302 on the corresponding side to swing upward through the hinged connecting rod 305, finally putting the pair of flip cover baffles 302 in the expanded state;

[0059] When the telescopic rod of the electric telescopic cylinder 311 is shortened, under the action of the hinge, the central swing arm 309 is driven to rotate in the opposite direction along the central axis 308, and the two ends of the central swing arm 309 drive the long connecting rod 306 and the short connecting rod 307 to close inward; the long connecting rod 306 and the short connecting rod 307 drive the triangular connecting plate 304 on the corresponding side to swing downward along the fixed coupling 312, and the triangular connecting plate 304 drives the L-shaped swing arm 303, the second roller shaft 300, the second roller 301 and the flip cover baffle 302 on the corresponding side to swing downward through the hinged connecting rod 305, so that the pair of flip cover baffles 302 are in a closed state.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
