Description

Technical Field

[0001] This invention relates to the field of livestock breeding technology, specifically to an electric, unmanned, total mixed ration (TMR) feed pusher. Background Technology Total mixed ration (TMR) feeding technology is a key technology in modern intensive animal husbandry. Its core lies in fully mixing roughage, concentrate and various additives in proportion and feeding them evenly to livestock.

[0002] Currently, total mixed ration (TMR) feeding is typically carried out using tractor-trailers or pushcarts. These vehicles are mostly manually operated, resulting in high labor intensity and feeding efficiency and accuracy easily affected by human factors. Uneven feed distribution on the ground frequently occurs during the pushing process: some areas have excessive feed accumulation, while others have insufficient feed. Operators often need to make repeated adjustments, and sometimes even stop the machine to manually assist in spreading the feed, affecting the continuity of operations.

[0003] Furthermore, spilled or leftover feed, if not promptly collected, will result in waste and environmental pollution. Currently, the process of collecting excess feed and returning it to the TMR (Total Mixed Ration) preparation machine for reuse mainly relies on manual operation, which is inefficient and increases labor costs.

[0004] Although automation technology has advanced, existing automated feeding equipment is limited in function, typically only performing the pushing task. It cannot achieve dynamic adjustment of feed, temporarily storing excess feed and replenishing it when insufficient, or automated and closed-loop recovery and replenishment of feed between the equipment and the stationary total mixed ration (TMR) preparer. This limits the level of automation and economic efficiency of the entire TMR feeding process. Summary of the Invention

[0005] To address the technical problems existing in the background art, the present invention provides an electric unmanned total mixed ration (TMR) pusher vehicle, which realizes full automation and intelligence of the total mixed ration TMR feed feeding process. It has the function of automatically balancing the distribution of feed on the ground during the feeding process, and can automatically dock with the total mixed ration TMR preparation machine to complete the recovery of leftover feed and the replenishment of fresh feed, significantly improving feeding efficiency, reducing feed waste, and lowering labor costs.

[0006] The technical solution adopted by this invention is: Electric, driverless total mixed ration (TMR) feed trolley, including: The pusher trolley body is equipped with an unmanned driving system.

A conveying pump and a connecting hose connecting the conveying pump to the middle of the right side of the push plate are provided on one side of the bin. The conveying pump is electrically connected to the unmanned driving system. When the conveying pump rotates forward, the total mixed ration in the hopper is conveyed to the push plate through the connecting hose and discharged. When the conveying pump rotates in reverse, the total mixed ration accumulated at the push plate is collected back into the hopper for temporary storage through the connecting hose.

[0007] Furthermore, the upper end of the pusher trolley body is provided with a positioning protrusion, and the upper part of the front wall of the hopper is provided with a retaining ring that is inserted into the positioning protrusion; the bottom of the hopper is provided with an upwardly extending top plate at the conveying pump connection pipe, and the lower part of the right wall of the hopper is provided with a receiving groove, the receiving groove having a through hole in the middle and a baffle at its lower opening; a baffle and a thrust leaf spring providing downward pushing force are slidably arranged in the receiving groove, and the lower end of the baffle abuts against the baffle; when the hopper is positioned by the retaining ring and the positioning protrusion and moves down to the working position, the top plate abuts against the baffle and pushes the baffle up, so that the through hole at the lower part of the baffle is connected to the through hole of the receiving groove and the conveying pump connection pipe, thereby forming a material channel.

[0008] Furthermore, it also includes: a total mixed ration (TMR) preparation machine, and an automatic loading and unloading recycling system installed on it; The automatic loading and unloading recycling system includes: a material guiding mechanism located at the discharge port of the total mixed ration (TMR) preparation machine, the material guiding mechanism including an openable and closable sealing plate, a material guiding base plate, and an extension plate hinged to the front end of the material guiding base plate; a lifting transmission mechanism located at the front of the TMR preparation machine, the lifting transmission mechanism consisting of transmission sprockets located on the left and right sides of the material guiding mechanism and a drive mechanism for driving their rotation; and guide rails located on the left and right sides of the transmission sprockets on both sides, the pulleys being rolled within the guide rails, including: a guide straight rail and a guide curved rail that smoothly transition between each other.

[0009] Furthermore, the chain of the transmission sprocket is provided with multiple sets of mounting seats, and the mounting seats are respectively provided with a locking mechanism for locking the lugs on the hopper, an extension plate adjustment mechanism for adjusting the angle of the extension plate, and a sealing plate locking mechanism for locking the sealing plate.

[0010] Furthermore, the ear-mounting mechanism is located in front of the transmission sprocket and includes: a connecting plate fixed on the central mounting base, and an ear-mounting seat fixed on its front plate surface. The ear-mounting seat is hinged with an ear-mounting lug. The ear-mounting seat and the ear-mounting lug cooperate with each other to ring and fix the ear-mounting lug on the lower part of the rear wall of the hopper.

[0011] The extension plate adjustment mechanism is arranged in parallel in front of the transmission sprocket, including: a pressure rod seat fixed on the highest mounting base, and an extension rod fixed thereon.

[0012] The sealing plate locking mechanism is housed between the transmission sprocket and the guide rail, and includes: a rod holder fixed on the lowest mounting base, and a rod lug hinged thereto. The rod holder and the rod lug cooperate with each other to ring and fix the sealing plate rod on the sealing plate.

[0013] Furthermore, the end of the guide curved track is provided with a stop block for abutting against the pulley on the rear wall of the hopper; the drive sprocket rotates in the forward direction, causing the hopper to rise to the highest point, the pulley enters the guide curved track from the guide straight track and abuts against the stop block, and the drive sprocket continues to rotate, forcing the hopper to flip inside the total mixed ration preparation machine with the pulley below it as the axis, thereby achieving unloading.

[0014] Furthermore, the slide plate on the lower frame of the total mixed ration (TMR) preparation machine is located directly below the extension plate.

[0015] The ear-hanging mechanism further includes: a slide rod disposed on the inner side wall of the ear-hanging lugs on both sides, the slide rod being slidably connected to the front wall of the slide plate; when the transmission sprocket rotates in the opposite direction, causing the discharge bin to descend to a specific position, the slide rod contacts the slide plate and pushes the ear-hanging lugs to rotate and open, so that the ear-hanging lugs are disengaged from the ear-hanging lug holder.

[0016] Furthermore, a stroke cylinder is provided on the front wall of the total mixed ration (TMR) preparation machine; a push rod is provided on the side wall of the hanging rod catch of the sealing plate clamping mechanism; when the sealing plate and the guide plate abut against each other and are in a closed state, the stroke end of the stroke cylinder extends and pushes the push rod, thereby causing the hanging rod catch to rotate and open, so that the sealing plate hanging rod is disengaged from the hanging rod catch seat.

[0017] The operating method of the electric, driverless total mixed ration (TMR) feed cart includes: Material recycling process: The pusher trolley drives to the front of the total mixed ration (TMR) preparation machine. The lifting transmission mechanism engages and fixes the hopper through the lug clamping mechanism and raises it. During the raising process, the extension plate adjustment mechanism adjusts the extension plate to a vertical position. After the hopper rises to the highest point, it flips over and pours the temporarily stored TMR into the TMR preparation machine. The lifting transmission mechanism moves in the opposite direction, lowers the empty hopper and returns it to the pusher trolley's hopper.

[0018] Material replenishment process: After the recycling is completed, the lifting transmission mechanism continues to move in the reverse direction, the sealing plate locking mechanism locks and fixes the sealing plate and raises it, opening the discharge port of the total mixed ration (TMR) preparation machine, allowing the material to fall into the hopper through the guiding mechanism; after the loading is completed, the lifting transmission mechanism moves in the forward direction, the sealing plate descends to the closed position, and the stroke cylinder triggers the sealing plate locking mechanism to release the sealing plate.

[0019] The beneficial effects of the electric unmanned total mixed ration (TMR) feed pusher of this invention: 1. The unmanned driving system controls the pusher vehicle to complete the basic pushing work; by controlling the forward and reverse rotation of the delivery pump and the connecting hose, the total mixed ration is replenished and temporarily stored; uneven feed distribution and waste are avoided, and the amount of total mixed ration on the ground is made uniform and balanced during the feeding process.

[0020] 2.

The described embodiments are only a part of the embodiments of this invention, not all of them. Without creative effort, all other embodiments based on the embodiments described in this invention are within the protection scope of this invention.

[0024] This invention relates to an electric, unmanned total mixed ration (TMR) feed pusher, such as... Figures 1 to 11 As shown, it includes: The pusher trolley body 110 contains an unmanned driving system. A lifting plate is slidably installed at the front end of the pusher trolley body 110.

The upper and lower ends of the thrust spring abut against the bottom of the upper trough of the trough 124 and the upper end of the baffle 125, respectively, and the lower end of the baffle 125 abuts against the baffle.

[0026] Before the hopper 120 is placed into the bin 113, the thrust leaf spring pushes the baffle 125 to the stop ear, and the perforation in the middle of the receiving groove 124 is blocked by the upper part of the baffle 125. When the hopper 120 is placed into the bin 113, the retaining ring 122 is fitted over the positioning protrusion 112 and limits the position of the hopper 120 in the bin 113. When the positioning protrusion 112 and the retaining ring 122 are fixed first, and the hopper 120 moves downward, the top plate 117 and the baffle 125 abut against each other and the baffle 125 slides upward along the receiving groove 124 until the through hole 126 connects with the perforation in the middle of the receiving groove 124.

[0027] When the drive unit of the conveying pump 115 is started to rotate forward, the total mixed ration in the silo 120 is discharged through the connecting hose 116 to the middle of the right side of the push plate 111; when the drive unit of the conveying pump 115 is started to rotate in reverse, the total mixed ration pushed on the ground by the push plate 111 gathers in the middle of the right side of the push plate 111, flows through the connecting hose 116 to the silo 120, and is temporarily stored in the silo 120 after being blocked by the baffle 121.

[0028] When there is too much total mixed ration on the ground, the total mixed ration is temporarily stored in the silo 120; when there is too little total mixed ration on the ground, the total mixed ration temporarily stored in the silo 120 is conveyed to the push plate 111 to improve the uniformity of the total mixed ration on the ground during the pushing process.

[0029] Total mixed rations temporarily stored in silo 120 are sent to total mixed ration preparation machine 20 for recycling; total mixed rations in total mixed ration preparation machine 20 can also be sent directly to silo 120.

[0030] A sealing plate 21 is provided at the discharge port of the front wall of the total mixed ration (TMR) preparation machine 20. A guide plate 22 is provided at the lower end of the discharge port of the front wall of the TMR preparation machine 20. The lower end of the sealing plate 21 abuts against the upper surface of the guide plate 22. The guide plate 22 is inclined downward. An extension plate 23 is provided at the front end of the guide plate 22 and is coplanar. The extension plate 23 is shaped like a "┏". Tension springs 24 are provided on the left and right sides of the guide plate 22 and the extension plate 23, respectively. The left and right sides of the guide plate 22 are respectively vertical. A guide plate 25 is provided, with its front end extending forward to below the extension plate 23. The extension plate 23 is provided with a through groove for accommodating the guide plate 25. A sealing plate 21 is provided with a sealing plate hanging rod 27 protruding to the left and right sides in the middle. A stroke cylinder 26 is provided at the sealing plate hanging rod 27 and fixed to the front wall of the total mixed ration preparation machine 20. The stroke end of the stroke cylinder 26 is inclined to the rear and downward. A sliding plate 28 is provided directly below the extension plate 23 and fixed to the lower frame of the total mixed ration preparation machine 20.

[0031] The sealing plate 21 has symmetrically arranged transmission sprockets 30 on its left and right sides.

[0032] A guide rail 40 is provided on the outer side of the transmission sprocket 30. The guide rail 40 has openings facing each other, and the pulley 123 is rolled inside it. The guide rail 40 includes a guide straight rail 41 and a guide curved rail 42 that are smoothly transitioned to each other. The guide straight rail 41 is fixedly connected to the front wall and lower frame of the total mixed ration (TMR) preparation machine 20, and the guide curved rail 42 is fixedly connected to the front wall of the TMR preparation machine 20. The end of the guide curved rail 42 is provided with a stop block 43 for abutting against the pulley 123.

[0033] Equal-height mounting seats 50 are hinged on both sides of the transmission sprocket 30. The mounting seats 50 are fastened to the front and rear outer sides of the transmission chain of the transmission sprocket 30. At least three sets of equal-height mounting seats 50 are provided, and each is fixed with a sealing plate snap-fit ​​mechanism 51, an extension plate adjustment mechanism 52, and a hanging ear snap-fit ​​mechanism 53.

[0034] The sealing plate clamping mechanism 51 is housed between the transmission sprocket 30 and the guide rail 40, and includes: A rod holder 510 is fixed on the lowest mounting base 50. A rod catch 511 is hinged on the rod holder 510. The rod holder 510 and the rod catch 511 are used to encircle the sealing plate rod 27. A push rod 512 is provided on the side wall of the rod catch 511. The push rod 512 is pushed by the stroke cylinder 26 and drives the rod catch 511 to rotate, so that the sealing plate rod 27 is disengaged from the rod holder 510.

[0035] The extension plate adjustment mechanism 52 is arranged in parallel in front of the transmission sprocket 30, and includes: A pressure rod seat 520 is fixed on the highest mounting base 50. An extension rod 521 is pressed and fixed on the pressure rod seat 520. The extension rod 521 is located at the corner of the lower part of the extension plate 23, thereby moving the extension rod 521 to an inclined state parallel to the guide bottom plate 22 and a vertical state.

[0036] The lug hook mechanism 53 is located in front of the drive sprocket 30 and includes: A connecting plate 530 is fixed on the middle mounting base 50. A hanging ear bracket 531 is fixedly provided on the front plate surface of the connecting plate 530. The hanging ear bracket 531 is symmetrically arranged on the left and right sides of the slide plate 28. A hanging ear 532 is hinged on the hanging ear bracket 531. The hanging ear bracket 531 and the hanging ear 532 are used to loop the hanging ear 127. A slide rod 533 is provided on the side wall opposite to the hanging ear 532 on both sides, which is slidably connected to the front wall of the slide plate 28.

[0037] The boom holder 510 and the lug holder 531 are configured as an upward-opening "U" shape, while the boom lug holder 511 and the lug lug holder 532 are configured as triangular plates with downward-extending protruding plates. The hinge shafts of the boom holder 510 and the boom lug holder 511 are located at their lower parts, while the hinge shafts of the lug lug holder 531 and the lug lug holder 532 are located at their upper parts. Torsion springs are respectively installed at the hinge shafts, so that the boom holder 510 and the boom lug holder 511 are in the state of ringing the boom 27, and the lug lug holder 531 and the lug lug holder 532 are in the state of ringing the lug 127. The push rod 512 is located at the upper part of the boom lug holder 511, and the slide rod 533 is located at the lower part of the lug lug holder 532.

[0038] When the total mixed ration (TMR) temporarily stored in the silo 120 is recovered to the TMR preparation machine 20, the pusher trolley body 110 stops in front of the TMR preparation machine 20 with the hopper 113 moving backward. The drive mechanism drives the transmission sprocket 30 to rotate forward. The extension plate adjustment mechanism 52 and the ear-hanging mechanism 53 in front of the transmission sprocket 30 move upward. The ear 127 contacts the triangular inclined surface of the ear-hanging clip 532, pushing the ear-hanging clip 532 to rotate until the bottom of the "U"-shaped groove of the ear-hanging clip seat 531. The ear-hanging clip 532 returns to its original state under the elastic force of the torsion spring and cooperates with the ear-hanging clip seat 531 to loop the ear 127, thereby fixing and driving the silo 120 to move upward. At this time, pulley 123 moves upward along guide rail 41, extension rod 521 contacts the lower part of extension plate 23, pushing extension plate 23 to rotate upward until tension spring 24 is above the hinge axis of guide bottom plate 22 and extension plate 23, so that extension plate 23 remains vertical. When the silo 120 is at its highest point on the drive sprocket 30, the pulley 123 below the silo 120 rolls from the guide straight rail 41 onto the guide curved rail 42 and abuts against the top block 43 of the stop wheel. The drive sprocket 30 continues to rotate in the forward direction, causing the silo 120 to rotate towards the upper opening of the total mixed ration (TMR) preparation machine 20 with the axis of the pulley 123 below as the center, and pouring the TMR temporarily stored in the silo 120 into the TMR preparation machine 20.

[0039] After the total mixed ration (TMR) is recovered, the drive mechanism drives the transmission sprocket 30 to rotate in the opposite direction. The hopper 120, which was tilted towards the upper part of the TMR preparation machine 20, returns to the state of opening upwards. The pulley 123 rolls from the guide curved rail 42 to the guide straight rail 41. The transmission sprocket 30 continues to rotate in the opposite direction, causing the hopper 120 to move downwards until it passes the vertical extension plate 23. The extension rod 521 contacts the front of the vertical extension plate 23, pushing the extension plate 23 to rotate downwards until the tension spring 24 is below the hinge axis of the guide bottom plate 22 and the extension plate 23, so that the extension plate 23 returns to the tilted state parallel to the guide bottom plate 22.

[0040] After the extension plate 23 returns to its inclined state parallel to the guide plate 22, the transmission sprocket 30 continues to rotate in the opposite direction, the slide rod 533 contacts the front wall of the slide plate 28, and pushes the ear hook 532 to rotate, so that the "U"-shaped groove of the ear hook seat 531 is in an open state, the ear hook seat 531 continues to move downward, and the ear 127 disengages from the bottom of the "U"-shaped groove of the ear hook seat 531.

[0041] The trolley body 110 is in a drivable state, the transmission sprocket 30 continues to rotate in the opposite direction, the sealing plate locking mechanism 51 located behind the transmission sprocket 30 moves upward, the ring-shaped sealing plate hanger 27 contacts the triangular inclined surface of the hanger lug 511, pushing the hanger lug 511 to rotate until the bottom of the "U"-shaped groove of the hanger seat 510, the hanger lug 511 returns to its original state under the elastic force of the torsion spring, and cooperates with the hanger seat 510 to ring-lock the sealing plate hanger 27, thereby fixing and driving the sealing plate 21 to move upward, so that the total mixed ration in the total mixed ration preparation machine 20 is sequentially sent to the hopper 120 through the discharge port, the guide bottom plate 22, and the extension plate 23.

[0042] After the total mixed ration is conveyed in the silo 120, the drive mechanism drives the transmission sprocket 30 to rotate in the forward direction. The sealing plate clamping mechanism 51 located behind the transmission sprocket 30 moves downward until the sealing plate 21 abuts against the guide bottom plate 22. The stroke end of the stroke cylinder 26 extends to push the push rod 512, which pushes the rod catch 511 to rotate, causing the "U"-shaped groove of the rod catch 510 to open. The rod catch 510 continues to move downward, and the sealing plate rod 27 disengages from the bottom of the "U"-shaped groove of the rod catch 510. Otherwise, the stroke end of the stroke cylinder 26 is in a retracted state.

8. The electric unmanned total mixed ration (TMR) feed cart according to claim 5, characterized in that: The total mixed ration (TMR) preparation machine (20) is provided with a stroke cylinder (26) on the front wall; A push rod (512) is provided on the side wall of the rod catch (511) of the sealing plate latching mechanism (51); When the sealing plate (21) and the guide plate (22) are in contact and in a closed state, the stroke end of the stroke cylinder (26) extends and pushes the push rod (512), thereby driving the lifting rod clasp (511) to rotate and open, so that the sealing plate lifting rod (27) is dislodged from the lifting rod clasp (510).

9. A method of operating an electric unmanned total mixed ration (TMR) feed cart as described in any one of claims 3-8, characterized in that, The process includes two parts: material recycling and material replenishment. Material recycling process: The pusher car drives to the front of the total mixed ration (TMR) preparation machine (20). The lifting transmission mechanism engages the fixed hopper (120) through the lug engagement mechanism (53) and raises it. During the raising process, the extension plate adjustment mechanism (52) adjusts the extension plate (23) to a vertical state. After the hopper (120) rises to the highest point, it flips over and pours the temporarily stored TMR into the TMR preparation machine (20). The lifting transmission mechanism moves in the opposite direction and lowers the empty hopper (120) and returns it to the pusher car hopper (113). Material replenishment process: After the recycling is completed, the lifting transmission mechanism continues to move in the opposite direction, the sealing plate clamping mechanism (51) clamps and fixes the sealing plate (21) and raises it, opening the discharge port of the total mixed ration preparation machine (20), so that the material falls into the silo (120) through the guiding mechanism; After the material is loaded, the lifting transmission mechanism moves forward, the sealing plate (21) descends to the closed position, and the stroke cylinder (26) triggers the sealing plate locking mechanism (51) to release the sealing plate (21).
