Description

Technical Field

[0001] This utility model belongs to the field of agricultural product transportation technology, and in particular relates to a shockproof buffer plate for agricultural product transportation. Background Technology

[0002] Agricultural product transportation refers to the logistics process of transporting various agricultural products (such as grains, vegetables, fruits, meat, and aquatic products) from their place of origin to processing enterprises, wholesale markets, retail outlets, or consumers. Its core links include post-harvest pre-cooling, grading, packaging, warehousing, loading and unloading, and multimodal transport (road, rail, waterway, or air). It is necessary to balance efficiency and cost while ensuring product freshness and reducing losses. During transportation, cold chain preservation, shockproof and pressure-resistant measures should be taken according to the different characteristics of agricultural products (such as perishability and seasonality). The Internet of Things (IoT) technology is used to monitor temperature and humidity and track the route. Efficient agricultural product transportation is of great significance for stabilizing market prices, ensuring food safety, promoting farmers' income, and coordinating urban and rural supply chains. It is a key component of the modern agricultural service system.

[0003] In existing technology applications, agricultural products generally have a large weight, and the dynamic load generated during transportation can easily cause structural damage to the buffer mechanism (such as the buffer plate and its matching spring elements). Specifically, this manifests as plastic deformation of the buffer plate or failure of the elastic element. This mechanical failure can cause the buffer plate to deflect, thereby affecting the levelness of its bearing plane, and ultimately leading to a decrease in the stability of subsequent cargo stacking and affecting the efficiency of loading and unloading operations.

[0004] Based on this, this utility model designs a shockproof buffer plate for transporting agricultural products to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the problem in existing technologies where, due to the generally large weight of agricultural products, the dynamic loads generated during transportation can easily cause structural damage to the buffer mechanism (such as the buffer plate and its matching spring elements). Specifically, this manifests as plastic deformation of the buffer plate or failure of the elastic elements. Such mechanical failures can cause the buffer plate to deflect, thereby affecting the levelness of its bearing plane, ultimately leading to a decrease in the stability of subsequent cargo stacking and affecting the efficiency of loading and unloading operations. Therefore, this utility model proposes a shockproof buffer plate for transporting agricultural products.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A shockproof agricultural product transportation buffer plate includes a buffer plate and a buffer assembly. The buffer assembly is fixedly connected to the bottom of the buffer plate. Two sliding grooves are opened in the buffer plate. A support device for limiting the position of the buffer plate is slidably connected in the sliding grooves. A locking device for increasing the support area of ​​the buffer plate is locked in the support device.

[0008] The support device includes a support plate, a connecting rod is fixedly connected inside the support plate, a rotating plate is sleeved on the connecting rod, and a base plate is fixedly connected outside the rotating plate.

[0009] As a further description of the above technical solution:

[0010] The support device also includes two sliding plates, which are symmetrically arranged in the groove. A connecting plate is symmetrically installed on one side of each sliding plate. A rotating shaft is fixedly connected inside the connecting plate. A movable plate is fitted over the rotating shaft. The support plate is fixedly connected to the outside of the two movable plates.

[0011] As a further description of the above technical solution:

[0012] A rotatable connection structure is formed between the rotating shaft and the movable plate, and a rotatable connection is formed between the connecting rod and the rotating plate.

[0013] As a further description of the above technical solution:

[0014] The lower surface of the base plate is fixedly connected with a rubber pad to prevent slippage.

[0015] As a further description of the above technical solution:

[0016] The locking device includes two frames and several limiting holes. The limiting holes are evenly opened inside the slide plate. The frames are fixedly connected to the front of the buffer plate. A sliding post is provided inside the frame. A handle is fixedly connected to the front of the sliding post. A baffle is provided on the outer sleeve of the sliding post. A return spring is provided on the outer sleeve of the sliding post. The sliding post is locked in one of the limiting holes.

[0017] As a further description of the above technical solution:

[0018] The sliding column and the frame form a sliding connection.

[0019] As a further description of the above technical solution:

[0020] One end of the pull-back spring is fixedly connected to the outside of the baffle, and the other end of the pull-back spring is fixedly connected to the inside of the frame.

[0021] As a further description of the above technical solution:

[0022] The inner diameter of the limiting hole is slightly smaller than the diameter of the cross-section of the sliding column, and the sliding column and the limiting hole are in close contact.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0024] 1. In this utility model, when the weight of the transported agricultural products acts on the buffer plate, the buffer plate is pressed down and moves downward, causing the sliding plate and the connecting plate to move synchronously, thereby causing the movable plate and the support plate to move together. During this process, the movable plate drives the bottom plate to move through the rotating plate, so that the bottom plate forms auxiliary support for the support plate, thereby limiting the excessive downward movement of the buffer plate, avoiding damage to the buffer components due to overtravel displacement, and ensuring the stability of the subsequent load-bearing performance of the buffer plate.

[0025] 2. In this utility model, when it is necessary to adjust the support area of ​​the buffer plate, the operator pulls the sliding column by the handle, so that it slides along the frame and the inner cavity of the buffer plate, and gets out of the constraint of the limiting hole. Then the sliding plate can move freely in the sliding groove. After the sliding plate moves to the target position, the handle is released, the pull spring applies an elastic restoring force to the baffle, pushes the sliding column to reset and lock into the corresponding limiting hole, and completes the fixation of the sliding plate position. This adjustment mechanism can expand the effective bearing area of ​​the buffer plate and adapt to the transportation needs of agricultural products of different specifications.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-4 ,

[0034] First embodiment:

[0035] This utility model provides a technical solution: a shockproof agricultural product transportation buffer plate 1, including a buffer plate 1 and a buffer assembly 2. The buffer assembly 2 is fixedly connected to the bottom of the buffer plate 1. Two sliding grooves 3 are opened in the buffer plate 1. A support device 4 for limiting the position of the buffer plate 1 is slidably connected in the sliding grooves 3. A locking device 5 for increasing the support area of ​​the buffer plate 1 is locked in the support device 4.

[0036] The support device 4 includes a support plate 45, a connecting rod 46 is fixedly connected inside the support plate 45, a rotating plate 47 is sleeved on the connecting rod 46, and a base plate 48 is fixedly connected to the outside of the rotating plate 47.

[0037] Specifically, such as Figures 2-3 As shown, the support device 4 also includes two sliding plates 41, which are symmetrically arranged in the slide groove 3. A connecting plate 42 is symmetrically installed on one side of the sliding plate 41. A rotating shaft 43 is fixedly connected inside the connecting plate 42. A movable plate 44 is sleeved on the rotating shaft 43. The rotational cooperation between the rotating shaft 43 and the movable plate 44 allows the support plate 45 to adaptively adjust its angle according to the downward pressure of the buffer plate 1. When the buffer plate 1 is pressed down, the movable plate 44 rotates around the rotating shaft 43, driving the support plate 45 to move synchronously, forming a multi-level linkage buffer mechanism. This design not only disperses the impact load, but also avoids stress concentration caused by rigid connection, effectively extending the service life of the support device 4.

[0038] The support plate 45 is fixedly connected to the outside of the two movable plates 44. The rotating shaft 43 and the movable plate 44 form a rotating connection structure. The connecting rod 46 and the rotating plate 47 form a rotating connection fit. A rubber pad for preventing slippage is fixedly connected to the lower surface of the base plate 48. The rubber pad is fixed to the lower surface of the base plate 48 through a vulcanization process. Its high coefficient of friction significantly increases the static friction with the bearing surface. In the transportation vibration environment, this fit can effectively suppress the lateral slippage of the support device 4. At the same time, the elastic deformation of the rubber can absorb high-frequency micro-vibrations and improve the overall shock absorption performance of the buffer system.

[0039] During operation, when the weight of the transported agricultural products acts on the buffer plate 1, the buffer plate 1 is pressed down and moves downward, causing the sliding plate 41 and the connecting plate 42 to move synchronously. This causes the movable plate 44 and the support plate 45 to move together. During this process, the movable plate 44 drives the bottom plate 48 to move through the rotating plate 47, so that the bottom plate 48 forms auxiliary support for the support plate 45, thereby limiting the excessive downward movement of the buffer plate 1, avoiding damage to the buffer assembly 2 due to overtravel displacement, and ensuring the stability of the subsequent load-bearing performance of the buffer plate 1.

[0040] Second embodiment:

[0041] Specifically, such as Figures 3-4 As shown, the locking device 5 includes two frames 52 and several limiting holes 51. The limiting holes 51 are evenly opened inside the slide plate 41. The frames 52 are fixedly connected to the front of the buffer plate 1. A sliding post 53 is provided inside the frames 52. A handle 54 is fixedly connected to the front of the sliding post 53. A baffle 55 is provided on the outer sleeve of the sliding post 53. A return spring 56 is provided on the outer sleeve of the sliding post 53. The sliding post 53 is locked in one of the limiting holes 51. The cross-sectional diameter of the sliding post 53 is slightly larger than the inner diameter of the limiting hole 51, forming a tight fit to ensure that the slide plate 41 is firmly locked after adjustment. This matching method uses frictional resistance to prevent the sliding post 53 from accidentally coming off due to vibration during transportation. At the same time, the elastic preload of the return spring 56 further enhances the positioning reliability and keeps the support area stable after adjustment.

[0042] The sliding column 53 and the frame 52 form a sliding connection. One end of the return spring 56 is fixedly connected to the outside of the baffle 55, and the other end of the return spring 56 is fixedly connected to the inside of the frame 52. The two ends of the return spring 56 are fixed to the baffle 55 and the frame 52 respectively. It stores elastic potential energy through the pre-compression state. When the sliding column 53 is pulled out of the limiting hole 51, the spring continuously applies a restoring force through the baffle 55 to ensure that the sliding column 53 automatically resets and locks into the target limiting hole 51 after adjustment, realizing the quick locking function of one-handed operation.

[0043] The inner diameter of the limiting hole 51 is slightly smaller than the diameter of the cross-section of the sliding column 53, and the sliding column 53 and the limiting hole 51 are in close contact.

[0044] When adjusting the support area of ​​the buffer plate 1 during operation, the operator pulls the sliding column 53 through the handle 54, causing it to slide along the frame 52 and the inner cavity of the buffer plate 1, thus disengaging from the constraint of the limiting hole 51. Subsequently, the slide plate 41 can move freely within the slide groove 3. After the slide plate 41 moves to the target position, the handle 54 is released, and the pull spring 56 applies an elastic restoring force to the baffle 55, pushing the sliding column 53 to reset and engage with the corresponding limiting hole 51, thus fixing the position of the slide plate 41. This adjustment mechanism can expand the effective bearing area of ​​the buffer plate 1 to meet the transportation needs of agricultural products of different specifications.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
