Description

Technical Field

[0001] The invention relates to the technical field of conveying boxes, in particular to a pea seedling conveying box with a fixing and protection function. Background Art

[0002] The pea seedling transport box is a rigid or semi-rigid container used for transporting and storing pea seedlings. The transport box uses internal accessories and positioning devices to ensure that the pea seedlings are firmly placed during transportation to avoid damage caused by vibration or movement.

[0003] Traditional pea seedling transport boxes typically utilize fixed, low-profile boxes for stacking and portability. However, this design neglects the need for seedlings to maintain their growth during transport. Limited growth space means the tops of the seedlings may extend beyond the box's limits, impacting their growth and potentially restricting their development or causing damage from squeezing. Furthermore, stacked boxes can be easily displaced or collided due to bumps and jolts during transport, further increasing the risk of seedling damage.

[0004] Based on the above situation, the present invention proposes a pea seedling conveying box with a fixed protection function. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings of insufficient growth space and poor stability during transportation, the present invention provides a pea seedling transport box with a fixed protection function.

[0006] The lifting box of claim 1, wherein the lifting frame is slidingly connected to a U-shaped lifting frame in the box body, the lifting frame is slidingly connected to a card block symmetrically distributed along the lifting frame, and a limiting slot is provided on the top of the card block, and a U-shaped stop bar symmetrically distributed along the box body is fixedly connected to the upper side of the box body, and the stop bar is used to support and block adjacent cards, the card block and the lifting frame are fixedly connected with a first spring, the lifting frame is slidably connected to a card rod corresponding to the card block, and a slot corresponding to the card rod is opened at the bottom of the box body, and the card rod of the lower lifting frame is inserted into the slot of the upper box body. When the card rod is inserted to the limit of the slot, the upper box body temporarily does not contact the lower lifting frame, and a second spring is fixedly connected between the card rod and the lifting frame.

[0007] Further description, a cross partition is provided at the bottom of the box body.

[0008] It is further explained that a groove is provided on the outer bottom of the box body for being matched with and stacked with the lifting frame of the lower layer.

[0009] To further illustrate, each side of the lifting frame is provided with a plurality of ventilation holes.

[0010] It is further explained that the clamping block moves upward to contact the adjacent baffle bar, and the contact surface of the clamping block is set as an arc surface, and the clamping block is squeezed and matched with the adjacent baffle bar through the arc surface.

[0011] The cam is mounted on a rear portion of the upper frame, and the cam is mounted on a rear portion of the upper frame. The cam is mounted on a rear portion of the upper frame. The cam is mounted on a rear portion of the lower frame.

[0012] It is further explained that the card holder contacts the corresponding push rod, and the upper part of the side surface of the card holder is set as a plane, and the lower part is set as an inclined surface. When the card holder is horizontally inserted into the card slot, the push rod contacts the plane of the card holder.

[0013] Further description, it also includes a guide frame symmetrically distributed along the box body, the guide frame is slidably connected to the box body, the push rod is slidably connected to the adjacent guide frame, a guide plate is slidably connected to the box body, the guide plate has inclined holes symmetrically distributed along the guide plate, the guide plate is slidably connected to the adjacent guide frame through the inclined holes, and a fourth spring is fixed between the box body and the guide plate.

[0014] Further description, it also includes a splint symmetrically distributed along the box body, the splint is slidably connected to the box body, the splint is provided with a wedge block symmetrically distributed along the splint, the wedge block is squeezed and matched with the adjacent L-shaped slide, and a fifth spring is fixed between the splint and the box body.

[0015] It is further explained that the wedge block is slidably connected to the adjacent clamping plate, and a tension spring is fixed between the wedge block and the adjacent clamping plate.

[0016] The beneficial effects of the present invention are as follows: when transporting seedlings, the present invention is raised through the lifting frame to extend the protection height, meet the sufficient space required for the growth of seedlings, and provide a better growth environment for the seedlings. When taking out the seedling transport box, the lifting frame is lowered to increase the storage space, increase the number of empty boxes transported, and improve transportation efficiency.

[0017] The air holes on the lifting frame of the present invention ensure air circulation for the seedlings during transportation, avoid problems such as excessive humidity and excessive carbon dioxide concentration caused by a closed environment, and contribute to the healthy growth of the seedlings.

[0018] The present invention utilizes the insertion and fitting design and automatic locking function of the upper box body and the lower lifting frame to significantly enhance the overall stability when multiple layers are stacked, and reduce the phenomenon of tipping or squeezing caused by vehicle bumps.

[0019] The present invention only needs to repeat the three steps of placing seedlings, pulling up the lifting frame and stacking the boxes to achieve the horizontal and vertical fixation of the box and the lifting frame as a whole, effectively preventing the seedling box and the lifting frame from shifting due to up and down shaking or left and right collisions during transportation, thereby reducing the risk of damage to the seedlings.

[0020] The present invention can release the lateral fixation of the box body and the lifting frame on that layer by pressing the guide plate of the corresponding layer backward according to the ability of the porter. In this way, during transportation, there is no need to release the lateral fixation of the box body and the lifting frame layer by layer from top to bottom. The transport boxes on that layer and above can be transported and separated as a whole without the need to transport the transport boxes individually.

[0021] The present invention moves the L-shaped slide plate upward to squeeze the adjacent wedge-shaped blocks, so that the clamping plate fixes the cultivation tray, thereby achieving the effect of fixing the pea seedlings and preventing the pea seedlings from moving freely, becoming loose and being damaged.

DETAILED DESCRIPTION

[0035] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the invention can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the scope of the invention to those skilled in the art.

[0036] Example 1: A pea seedling transport box with fixed protection function, such as Figures 1-4As shown, it includes a box body 1, a cross partition is set at the bottom of the box body 1, which is used to place pea seedlings on different cultivation trays in different partitions, a groove is opened at the bottom outside the box body 1, and the groove is overlapped with the lifting frame 2 of the lower layer, and a mouth-shaped lifting frame 2 is slidably connected in the up and down directions inside the box body 1, and a plurality of air holes are opened on the front, back, left and right sides of the lifting frame 2 to meet the air demand of the pea seedlings during transportation. The front and back parts of the outer side of the lifting frame 2 are slidably connected in the left and right directions with a card block 3 symmetrically distributed along the lifting frame 2, and a U-shaped limiting groove is opened in the middle of the top of the card block 3, and a U-shaped baffle 30 symmetrically distributed along the left and right sides of the box body 1 is laterally fixed on the upper side of the inner side of the box body 1 1, the blocking bar 301 is used to support the adjacent card block 3, the card block 3 moves upward to contact the adjacent blocking bar 301, and the contact surface of the card block 3 is set to an arc surface, and the card block 3 is squeezed and matched with the adjacent blocking bar 301 through the arc surface. A first spring 4 is fixed between the card block 3 and the lifting frame 2, and a card rod 5 corresponding to the card block 3 is slidably connected on the lifting frame 2 in the up and down directions. A slot 501 corresponding to the card rod 5 is opened at the bottom of the box body 1, and the card rod 5 on the lower lifting frame 2 is inserted into the slot 501 of the upper box body 1. When the card rod 5 is inserted to the limit of the slot 501, the upper box body 1 does not contact the lower lifting frame 2 temporarily, and a second spring 6 is fixed between the card rod 5 and the lifting frame 2.

[0037] When the box 1 is lifted up, the lifting frame 2 is lifted up to extend the protective height, meet the sufficient space required for the growth of seedlings, and provide a better growth environment for the seedlings. When the box 1 is lifted up, the lifting frame 2 is lowered to increase the storage space, increase the number of empty boxes to be transported, and improve the transportation efficiency.

[0038] Moreover, the air holes on the lifting frame 2 of the present invention ensure air circulation for the seedlings during transportation, avoiding problems such as excessive humidity and excessive carbon dioxide concentration caused by a closed environment, and contributing to the healthy growth of the seedlings.

[0039] Afterwards, the next box body 1 containing pea seedlings is stacked on the lifting frame 2 after the lower layer is moved out. During the stacking process, the card rod 5 of the lower layer is longitudinally inserted into the slot 501 of the upper box body 1. When the card rod 5 is inserted to the limit of the slot 501, the upper box body 1 does not contact the lower lifting frame 2 temporarily. The upper box body 1 continues to be lowered under the action of its own gravity until the groove is opened on the outer bottom and is stuck on the lower lifting frame 2, thereby squeezing the card rod 5 of the lower layer to slide downward relative to the lower lifting frame 2, and the second spring 6 is compressed until the card rod 5 of the lower layer is longitudinally inserted into the lower card When the upper box 1 is removed, the limit of the lower card rod 5 on the lower card block 3 is automatically released, so that the card block 3 can be separated from the baffle 301, so that the lifting frame 2 can move downward and reset.

[0040] In this way, the present invention utilizes the insertion and fitting design and automatic locking function of the upper box body 1 and the lower lifting frame 2 to significantly enhance the overall stability during multi-layer stacking and reduce the dumping or squeezing phenomenon caused by vehicle bumps.

[0041] like Figure 5-Figure 8 As shown, it also includes a card frame 7 corresponding to the card rod 5, and the card frame 7 is slidably connected to the side of the box body 1 near the slot 501 in the front and rear directions. A card slot 701 is opened on the upper side of the card rod 5, and the card slot 701 on the lower card rod 5 is aligned with the card frame 7 on the upper layer. The card frame 7 on the upper layer slides horizontally and is inserted into the card slot 701 of the lower card rod 5. A third spring 8 is fixed between the card frame 7 and the box body 1. The front and rear parts of the box body 1 are both slidably connected along the up and down directions with L-shaped slides 9 symmetrically distributed along the left and right sides of the box body 1. The top of the L-shaped slide 9 contacts the upper side of the lifting frame 2. A pushing surface 901 is provided on one side of the lifting frame 2 close to each L-shaped slide 9. The pushing surface 901 moves upward to contact the adjacent L-shaped slide 9 and drives the L-shaped slide 9 to slide upward. A push rod 10 is provided on the lower side of the L-shaped slide 9. The push rod 10 corresponds to the card rack 7. The card rack 7 contacts the corresponding push rod 10, and the upper part of the side surface contacted by the card rack 7 is set to a plane, and the lower part is set to an inclined surface. The push rod 10 is squeezed and matched with the inclined surface of the corresponding card rack 7. When the card rack 7 is horizontally inserted into the card slot 701, the push rod 10 contacts the plane of the card rack 7.

[0042] Although the upper box 1 can be firmly fixed to the lower lifting frame 2 by the mutual restriction of the lower clamping rod 5 and the upper box 1 slot 501, it only prevents the box 1 and the lifting frame 2 from shifting laterally, and cannot prevent them from shaking up and down. Therefore, the following specific operations are used to solve this problem:

[0043] When the next box 1 containing pea seedlings is stacked on the lifting frame 2 after the lower layer is moved out, so that the lower card rod 5 is inserted into the slot 501 of the upper box 1, the card slot 701 on the lower card rod 5 is aligned with the upper card rack 7, and then the upper lifting frame 2 is pulled upward, so that the pushing surface 901 thereon moves upward until it contacts the upper side of the adjacent L-shaped slide 9, and the push rod 10 is driven to slide upward by the L-shaped slide 9. The push rod 10 squeezes the inclined surface of the adjacent upper card rack 7, so that the card rack 7 slides toward the side of the compressed third spring 8 until the upper card rack 7 is horizontally inserted into the card slot 701 of the lower card rod 5, so that the upper box 1 will not shake up and down relative to the lifting frame 2 of the lower layer.

[0044] When it is necessary to release the mutual limitation between the bracket 7 and the slot 701, it is necessary to push the lifting frame 2 of each layer downward before removing the box body 1, thereby driving the pushing surface 901 to move downward and away from the upper side of the L-shaped slide 9. At this time, the third spring 8 resets and drives the bracket 7 to slide out of the slot 701 in the opposite direction, and the limitation can be released. Then the upper side of the lifting frame 2 drops to contact the top of the adjacent L-shaped slide 9, and pushes the L-shaped slide 9 to slide downward and reset.

[0045] In this way, combined with Examples 1 and 2, the present invention only needs to continuously repeat the three-step operation of placing seedlings, pulling up the lifting frame 2 and stacking the box body 1 to achieve the overall horizontal and vertical fixation of the box body 1 and the lifting frame 2, effectively preventing the seedling box body 1 and the lifting frame 2 from shifting due to up and down shaking or left and right collisions during transportation, thereby reducing the risk of damage to the seedlings.

[0046] like Figure 9 and Figure 10 As shown, it also includes a guide frame 11 symmetrically distributed along the box body 1, the guide frame 11 is slidably connected to the box body 1, and the push rod 10 is slidably connected to the adjacent guide frame 11. When the L-shaped slide 9 drives the push rod 10 to move up and down, the push rod 10 slides up and down along the guide frame 11. A guide plate 12 is slidably connected to the box body 1, and the guide plate 12 has inclined holes symmetrically distributed along the guide plate 12. The guide plate 12 is slidably connected to the adjacent guide frame 11 through the inclined holes, and a fourth spring 13 is fixed between the box body 1 and the guide plate 12.

[0047] Since the above operation can prevent the box 1 from sliding up and down relative to the adjacent lifting frame 2, it is necessary to release the horizontal fixation of the box 1 and the lifting frame 2 layer by layer from top to bottom. In this way, when it is necessary to transfer, it is necessary to unlock and transfer layer by layer, which is a more troublesome operation. For example:

[0048] If there are ten layers of such conveying boxes stacked in each stack in the conveying vehicle, when they need to be transported down, they can only be transported individually layer by layer. However, by setting the guide plate 12, the present invention can choose to press the guide plate 12 of the corresponding layer backward according to the ability of the porter. For example, by pressing the guide plate 12 of the fifth layer backward, the fourth spring 13 is compressed, and the guide plate 12 squeezes the two adjacent guide frames 11 of the fifth layer close to each other through the inclined hole, thereby driving the push rod 10 to detach from the plane of the bracket 7. At this time, the bracket 7 slides out of the slot 701 in the opposite direction under the action of the third spring 8, and presses against the end of the adjacent push rod 10 by the side, so as to release the limit between the lifting frame 2 of the fifth layer and the box body 1 of the sixth layer, so that the conveying boxes of the sixth layer and above can be transported and detached as a whole without the need to transport the conveying boxes individually.

[0049] Since the bracket 7 is against the end of the adjacent push rod 10 through the side, the guide plate 12 will not reset temporarily when the guide plate 12 is released, and the fourth spring 13 still maintains a compressed state. The specific reset operation is as follows: when it is necessary to push the lifting frame 2 down to take the seedlings, the lifting frame 2 drives the push rod 10 downward and gradually separates from the side of the bracket 7 by pushing the L-shaped slide 9. At this time, the fourth spring 13 resets and drives the guide plate 12 of the fifth layer to slide forward and reset. The guide plate 12 squeezes the two adjacent guide frames 11 of the fifth layer away from each other through the inclined hole until they re-contact the inclined surface of the adjacent bracket 7.

[0050] like Figure 11 and Figure 12 As shown, it also includes a splint 14 symmetrically distributed along the left and right sides of the box body 1, and the splint 14 is slidably connected to the box body 1 along the front and rear directions. A wedge block 15 symmetrically distributed along the left and right sides of the splint 14 is slidably connected to the splint 14, and the wedge block 15 is squeezed and fitted with the adjacent L-shaped slide 9. A fifth spring 16 is fixed between the splint 14 and the box body 1, and a tension spring 17 is fixed between the wedge block 15 and the adjacent splint 14.

[0051] Pea seedlings are usually placed on a cultivation tray, and four cultivation trays are divided into four sections of the box 1. The L-shaped slide 9 moves upward to squeeze the adjacent wedge blocks 15, so that the splint 14, the wedge blocks 15 and the tension spring 17 move as a whole toward the side close to the adjacent cultivation tray. The fifth spring 16 is compressed. When the splint 14 contacts the cultivation tray of a certain range of sizes, the splint 14 stops moving, and the wedge blocks 15 continue to be squeezed and slide relative to the splint 14 toward the side of the tension spring 17. In this way, the cultivation tray is fixed by the splint 14, so as to achieve the effect of fixing the pea seedlings and prevent the pea seedlings from moving loose and damaged at will.

[0052] When it is necessary to push the lifting frame 2 down to take seedlings, the lifting frame 2 pushes the L-shaped slide 9 to slide downward, so that the L-shaped slide 9 no longer squeezes the wedge block 15, and the tension spring 17 and the fifth spring 16 gradually reset, so that the wedge block 15 and the splint 14 gradually reset, thereby loosening the cultivation plate.

[0053] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. The scope of the following claims is to be accorded the broadest interpretation so as to encompass all modifications and equivalent structures and functions.
