Description

Technical Field

[0001] This invention relates to the field of bulk feed semi-trailer transport vehicles, specifically a bulk feed semi-trailer transport vehicle. Background Technology

[0002] With economic development, large-scale and intensive livestock production methods have developed rapidly. Bagged feed is increasingly unable to meet the needs of modern livestock production, and bulk feed has become a key to the development of modern livestock. Among them, bulk feed transport vehicles are one of the important factors restricting this key. Because semi-trailers have a permitted body length and large overall volume, they can provide a large loading capacity. Therefore, bulk feed semi-trailer transport vehicles have gradually become a major market demand.

[0003] When using semi-trailer trucks to transport bulk feed, the feed often piles up in the truck bed or is damaged by impact when the road surface is rugged and the speed is high. The loading of feed usually causes dust to spread, and it is difficult to unload the feed completely by its own weight, so manual assistance is required.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a bulk feed semi-trailer transport vehicle. Summary of the Invention

[0005] The purpose of this invention is to provide a semi-trailer for transporting bulk feed to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bulk feed semi-trailer transport vehicle, comprising a chassis and a resistance spring, wherein a driving wheel is provided under the chassis, and a connecting hole is provided in the middle of the left end of the chassis, and lifting rods are symmetrically rotatably connected to the front and rear sides of the left side of the chassis, and a sleeve is sleeved on the upper end of the lifting rods, and telescopic rods are symmetrically rotatably connected to the front and rear sides of the right side of the chassis, and a truck bed is rotatably connected above the telescopic rods, and a push rod is rotatably connected to the right end of the truck bed, and a sealing door is rotatably connected to the lower end of the push rod, the resistance spring is fixedly connected to the lower surface of the inner wall of the truck bed, and a bottom frame is fixedly connected above the resistance spring, a resistance rod is provided below the bottom frame, and partitions are symmetrically fixedly connected to the front and rear sides above the bottom frame, a power assembly is provided on the upper part of the truck bed, and a unloading assembly is provided on the left side of the power assembly, and a shielding assembly is provided on the right side of the unloading assembly.

[0007] Furthermore, the sleeve is rotatably connected to the truck bed, and the bottom frame is elastically connected to the truck bed through a resistance spring. The two ends of the resistance rod are fixedly connected to the truck bed and the bottom frame, respectively, and the sealing door is rotatably connected to the truck bed.

[0008] Furthermore, the power assembly includes a motor and a drive wheel. The motor is fixedly connected to the left side of the truck bed, and the output end of the motor is fixedly connected to the drive wheel. The drive wheel is rotatably connected to the truck bed, and the drive wheel is a double-pulley.

[0009] Furthermore, the power assembly also includes a threaded rod and a transmission wheel. The threaded rod is symmetrically rotatably connected to the front and rear sides of the upper part of the truck bed, and the transmission wheel is fixedly connected to the left end of the threaded rod. The transmission wheel and the drive wheel form a transmission structure through a belt.

[0010] Furthermore, the unloading assembly includes a straight plate, a cavity, and a sliding cavity. The left side of the threaded rod is provided with a straight plate, and the upper part of the straight plate is provided with a cavity. The lower part of the straight plate is provided with a sliding cavity.

[0011] Furthermore, the unloading assembly also includes a compression spring, a push plate, and a slide groove. A compression spring is fixedly connected inside the slide cavity, and a push plate is fixedly connected to the lower end of the compression spring. Slide grooves are symmetrically opened on the lower parts of the push plate and the straight plate, and the push plate and the straight plate are slidably connected to the partition through the slide grooves.

[0012] Furthermore, the shielding assembly includes a sliding plate, a sliding hole, and a rainproof cloth. The left side of the threaded rod is provided with a sliding plate, and the lower part of the sliding plate is provided with a sliding hole. The upper outer periphery of the sliding plate is fixedly connected to the rainproof cloth, and the sliding plate is slidably connected to the threaded rod through the sliding hole. The leftmost sliding plate is fixedly connected to the straight plate.

[0013] Furthermore, connecting components are symmetrically arranged on both the upper and lower sides of the cavity and the sliding hole of the rightmost slide plate. The connecting components include a cavity, a slot and an electromagnetic plate. Cavities are symmetrically opened on both the upper and lower sides of the cavity and the sliding hole of the rightmost slide plate, and a slot is opened on one side of the cavity. An electromagnetic plate is fixedly connected in the slot.

[0014] Furthermore, the connecting assembly also includes a retaining ring, a retaining rod, a retaining plate, and a threaded clip. A retaining ring is fixedly connected inside the retaining cavity, and a retaining rod is provided inside the retaining ring. One end of the retaining rod is fixedly connected to a retaining plate, and the other end of the retaining rod is fixedly connected to a threaded clip.

[0015] Furthermore, the locking rod is slidably connected to the locking cavity, and the threaded locking clip is elastically connected to the locking cavity via a snap ring, and the threaded locking clip is threadedly connected to the threaded rod.

[0016] This invention provides a bulk feed semi-trailer with the following advantages: during use, it can buffer the vibration generated when the vehicle is driving on bumpy roads, reduce the impact on the feed, and spread the feed evenly when loading. After delivery to the destination, it can also assist in unloading, thus completing the unloading without manual assistance. Furthermore, it can prevent dust from spreading above the truck bed during loading and unloading.

[0017] 1. When loading feed, the resistance value of the resistance rod is first lowered. After the feed falls onto the bottom frame, the resistance spring is compressed by the bottom frame, causing the spring to vibrate up and down inside the truck bed, thus distributing the feed evenly within the bottom frame. After loading, the resistance value of the resistance rod is then increased. When the vehicle is traveling on bumpy roads, the resistance spring, in conjunction with the resistance rod, can buffer the vibrations generated, thereby reducing the impact on the feed. At the same time, the partition can divide the feed into sections, preventing excessive accumulation of feed in the bottom frame due to inertia during travel. In summary, this invention can buffer the vibrations generated when the vehicle is traveling on bumpy roads, reduce the impact on the feed, and ensure even distribution of feed during loading.

[0018] 2. When loading feed, the present invention starts the motor, which causes the drive wheel to rotate the threaded rod inside the truck bed via the transmission wheel. At this time, the electromagnetic plate inside the slide plate is de-energized while the electromagnetic plate inside the straight plate is energized. The threaded clip inside the slide plate is pressed against the surface of the threaded clip by the snap ring, and the electromagnetic plate inside the straight plate attracts the clip plate. The clip rod can then pull the threaded clip away from the threaded rod. The threaded rod can then drive the rightmost slide plate to move through the threaded clip, thereby unfolding the rainproof cloth to cover the top of the truck bed and leaving enough space above the truck bed for loading feed. This allows the dust generated by the impact during feed loading to fall back into the truck bed after being covered by the rainproof cloth, preventing dust from spreading. After the feed is loaded, the threaded rod continues to drive the slide plate to completely close the top of the truck bed, covering the feed inside the truck bed and preventing the feed from getting damp in rain or snow during transportation. In summary, when loading feed, dust can be prevented from spreading above the truck bed, and the feed can be prevented from getting wet from rain or snow during transportation.

[0019] 3. During unloading, the lifting rod can raise the left end of the bucket via the sleeve, allowing the bucket to rotate on the chassis. The telescopic rod assists the lifting rod in raising the bucket. Simultaneously, the push rod pulls the sealing door to open the right side of the bucket, allowing the feed loaded inside to slide automatically out of the bottom frame under gravity along the inclined plane formed by the rotating bucket. The motor is then restarted, energizing the electromagnetic plate inside the sliding plate and de-energizing the electromagnetic plate inside the straight plate. The threaded rod can then drive the straight plate to slide within the bottom frame via the threaded clamp, pushing the feed loaded in the bottom frame to the right to assist unloading. As the straight plate moves... The leftmost slide can move the other slides to retract the rainproof cloth while keeping it closed over the truck bed, preventing dust from spreading from above. During the movement of the straight plate, the push plate can be kept in contact with the inner wall of the bottom frame by the action of the compression spring, thus ensuring complete unloading. The partition can restrict the straight plate and push plate through the slide groove to prevent them from tilting during movement, which would lead to incomplete unloading. In summary, after reaching the destination, assisted unloading can be carried out, thus completing the unloading without manual assistance, and preventing dust from spreading above the truck bed during unloading.

A shielding assembly 16 is provided to the right of the unloading assembly 15.

[0029] Please see Figures 1 to 5 The sleeve 5 is rotatably connected to the truck bed 7, and the bottom frame 11 is elastically connected to the truck bed 7 via a resistance spring 10. The two ends of the resistance rod 12 are fixedly connected to the truck bed 7 and the bottom frame 11 respectively, and the sealing door 9 is rotatably connected to the truck bed 7. The power assembly 14 includes a motor 1401 and a drive wheel 1402. The motor 1401 is fixedly connected to the left side of the truck bed 7, and the drive wheel 1402 is fixedly connected to the output end of the motor 1401. The drive wheel 1402 is rotatably connected to the truck bed 7 and is a double-pulley. The power assembly 14 also includes a threaded rod 1403 and a transmission wheel 1404. The threaded rod 1403 is symmetrically rotatably connected to the front and rear sides of the upper part of the truck bed 7, and the transmission wheel 1404 is fixedly connected to the left end of the threaded rod 1403. Wheel 1404 forms a transmission structure with drive wheel 1402 via belt. Unloading assembly 15 includes straight plate 1501, cavity 1502 and sliding cavity 1503. Straight plate 1501 is provided on the left side of threaded rod 1403, and cavity 1502 is provided on the upper part of straight plate 1501. Sliding cavity 1503 is provided on the lower part of straight plate 1501. Unloading assembly 15 also includes compression spring 1504, push plate 1505 and sliding groove 1506. Compression spring 1504 is fixedly connected in sliding cavity 1503, and push plate 1505 is fixedly connected to the lower end of compression spring 1504.

[0030] The specific operation is as follows: When loading feed, first lower the resistance value of the resistance rod 12. After the feed falls onto the bottom frame 11, the resistance spring 10 can be compressed through the bottom frame 11, causing the spring to drive the bottom frame 11 to vibrate up and down inside the truck bed 7, so that the feed is evenly distributed inside the bottom frame 11. After loading is completed, raise the resistance value of the resistance rod 12 so that when the vehicle is driving on bumpy roads, the resistance spring 10 can work with the resistance rod 12 to buffer the vibration generated, thereby reducing the impact on the feed. At the same time, the partition 13 can divide the feed into sections to avoid... The feed accumulates excessively within the bottom frame 11 due to inertia during driving. Therefore, this system can buffer vibrations generated when the vehicle is traveling on bumpy roads, reducing the impact on the feed. Furthermore, it allows for even distribution of the feed during loading. During unloading, the lifting rod 4 can raise the left end of the truck bed 7 via the sleeve 5, allowing the truck bed 7 to rotate on the chassis 1. The telescopic rod 6 assists the lifting rod 4 in raising the truck bed 7, while the push rod 8 pulls the sealing door 9 to open the right side of the truck bed 7, allowing the feed loaded inside to rotate along the truck bed 7 under gravity. The formed ramp automatically slides out of the truck bed 7 from the bottom frame 11. The motor 1401 is restarted. At this time, the electromagnetic plate 1703 in the slide plate 1601 is energized and the electromagnetic plate 1703 in the straight plate 1501 is de-energized. The threaded rod 1403 can then drive the straight plate 1501 to slide within the bottom frame 11 through the threaded clip 1707, thereby pushing the feed loaded in the bottom frame 11 to the right to assist in unloading. When the straight plate 1501 moves, it can drive the other slide plates 1601 to move through the leftmost slide plate 1601, retracting the rainproof cloth 1603 while keeping the rainproof cloth 1603 in contact with the ground. The enclosure above the truck bed 7 prevents dust from spreading from above it. During the movement of the straight plate 1501, the push plate 1505 can be kept in contact with the inner wall of the bottom frame 11 under the action of the compression spring 1504, thus ensuring complete unloading. The partition plate 13 can restrict the straight plate 1501 and the push plate 1505 through the sliding groove 1506 to prevent them from tilting during movement, which would lead to incomplete unloading. In summary, after reaching the destination, assisted unloading can be carried out, thus completing the unloading without manual assistance, and preventing dust from spreading above the truck bed 7 during unloading.

[0031] Please see Figures 4 to 7The shielding component 16 includes a sliding plate 1601, a sliding hole 1602, and a rainproof cloth 1603. A sliding plate 1601 is located on the left side of the threaded rod 1403, and a sliding hole 1602 is located on the lower part of the sliding plate 1601. A rainproof cloth 1603 is fixedly connected to the upper outer periphery of the sliding plate 1601, and the sliding plate 1601 is slidably connected to the threaded rod 1403 through the sliding hole 1602. The leftmost sliding plate 1601 is fixedly connected to the straight plate 1501. Connecting components 17 are symmetrically arranged on the upper and lower sides of the cavity 1502 and the sliding hole 1602 of the rightmost sliding plate 1601. The connecting components 17 include a retaining cavity 1701, a retaining slot 1702, and an electromagnetic plate 1703. The upper and lower sides of the cavity 1502 and the sliding hole 1602 of the rightmost sliding plate 1601 are symmetrically arranged. The connecting assembly 17 has symmetrically arranged cavities 1701 on both sides, and a slot 1702 is provided on one side of the cavity 1701. An electromagnetic plate 1703 is fixedly connected in the slot 1702. The connecting assembly 17 also includes a retaining spring 1704, a retaining rod 1705, a retaining plate 1706, and a threaded clip 1707. The retaining spring 1704 is fixedly connected in the cavity 1701, and a retaining rod 1705 is provided inside the retaining spring 1704. One end of the retaining rod 1705 is fixedly connected to the retaining plate 1706, and the other end of the retaining rod 1705 is fixedly connected to the threaded clip 1707. The retaining rod 1705 is slidably connected to the cavity 1701, and the threaded clip 1707 is elastically connected to the cavity 1701 through the retaining spring 1704. The threaded clip 1707 is threadedly connected to the threaded rod 1403.

[0032] The specific operation is as follows: When loading feed, starting the motor 1401 causes the drive wheel 1402 to drive the threaded rod 1403 to rotate inside the truck bed 7 via the transmission wheel 1404. At this time, the electromagnetic plate 1703 inside the slide plate 1601 is de-energized while the electromagnetic plate 1703 inside the straight plate 1501 is energized. The threaded clip 1707 inside the slide plate 1601 is then pressed against the surface of the threaded clip 1707 by the retaining spring 1704. Meanwhile, the electromagnetic plate 1703 inside the straight plate 1501 attracts the clamping plate 1706. The threaded clip 1707 can then be pulled away from the threaded rod 1403 by the clamping rod 1705. The threaded rod 1403 can then drive the rightmost end through the threaded clip 1707. The sliding plate 1601 moves, thereby unfolding the rainproof cloth 1603 to cover the top of the truck bed 7 and leaving enough space above the truck bed 7 for loading feed. This allows dust generated by the impact during feed loading to fall back into the truck bed 7 after being covered by the rainproof cloth 1603, preventing dust from spreading. After the feed is loaded, the threaded rod 1403 continues to drive the sliding plate 1601 to completely close the top of the truck bed 7, covering the feed loaded in the truck bed 7 and preventing the feed from getting damp in rain or snow during transportation. In summary, when loading feed, dust can be prevented from spreading above the truck bed 7, and the feed can be prevented from getting wet from rain or snow during transportation.

[0033] In summary, this type of bulk feed semi-trailer transport vehicle, when loading feed, first lowers the resistance value of the resistance rod 12, starts the motor 1401, and the drive wheel 1402 drives the threaded rod 1403 to rotate inside the truck bed 7 via the transmission wheel 1404. At this time, the electromagnetic plate 1703 in the slide plate 1601 is de-energized and the electromagnetic plate 1703 in the straight plate 1501 is energized. The threaded clip 1707 in the slide plate 1601 is then pressed against the surface of the threaded clip 1707 by the retaining spring 1704, while the electromagnetic plate 1703 in the straight plate 1501 attracts the clamp plate 1706. The threaded clip 1707 can then be pulled away from the threaded rod 1403 by the clamp rod 1705. The threaded rod 1403 can then drive the rightmost slide plate 1601 to move via the threaded clip 1707. The rainproof cloth 1603 is unfolded to cover the top of the truck bed 7, leaving sufficient space above the truck bed 7 for loading feed. This allows dust generated during feed loading to fall back into the truck bed 7 after being covered by the rainproof cloth 1603, preventing dust from spreading. After the feed falls onto the bottom frame 11, the bottom frame 11 compresses the resistance spring 10, causing the spring to vibrate the bottom frame 11 up and down inside the truck bed 7, distributing the feed evenly within the bottom frame 11. After the feed is loaded, the resistance value of the resistance rod 12 is increased, so that when the vehicle travels on bumpy roads, the resistance spring 10, in conjunction with the resistance rod 12, can buffer the vibrations generated, thereby reducing the impact on the feed. At the same time, the partition 13 can divide the feed into sections to prevent feed from being spread out. Due to inertia generated during travel, the feed accumulates excessively within the bottom frame 11. The threaded rod 1403 continues to drive the sliding plate 1601 to completely seal the top of the truck bed 7, protecting the feed inside and preventing it from getting damp during transport in rain or snow. During unloading, the lifting rod 4 can raise the left end of the truck bed 7 via the sleeve 5, allowing the truck bed 7 to rotate on the chassis 1. The telescopic rod 6 assists the lifting rod 4 in raising the truck bed 7. Simultaneously, the push rod 8 pulls the sealing door 9 to open the right side of the truck bed 7, allowing the feed inside the truck bed 7 to automatically slide out of the bottom frame 11 under gravity along the inclined plane formed by the rotation of the truck bed 7. The motor 1401 is restarted, energizing the electromagnetic plate 1703 inside the sliding plate 1601 and the straight plate 1501. When the electromagnetic plate 1703 is de-energized, the threaded rod 1403 can drive the straight plate 1501 to slide within the bottom frame 11 via the threaded clip 1707, thereby pushing the feed loaded in the bottom frame 11 to the right to assist in unloading. When the straight plate 1501 moves, it can drive the other sliding plates 1601 to move via the leftmost sliding plate 1601, retracting the rainproof cloth 1603 while keeping the rainproof cloth 1603 closed over the top of the truck bed 7 to prevent smoke and dust from spreading from above the truck bed 7. During the movement of the straight plate 1501, the push plate 1505 can be kept in contact with the inner wall of the bottom frame 11 under the action of the compression spring 1504, thereby ensuring complete unloading. The partition plate 13 can restrict the straight plate 1501 and the push plate 1505 through the sliding groove 1506 to prevent them from tilting during movement.This results in incomplete unloading.
