[0060] like Figures 1 to 3 As shown, the stepping base plate 1 for material transportation of the present application includes a base plate structure 10, at least two T-shaped brackets 11, at least two movable plates 12 and at least two driving members 13. At least two T-shaped brackets 11 are distributed in an array on the base plate structure 10, and the T-shaped brackets 11 constitute at least two tracks. At least two movable plates 12 are arranged on the T-shaped brackets 11 and can move along the tracks. The movable plates 12 are made of corrosion-resistant materials, such as stainless steel or polytetrafluoroethylene. At least two driving members 13 are connected to the base plate structure 10 and drive the movable plates 12 to move. When in use, the material is placed on the movable plate 12, and the driving member 13 drives the movable plate 12 to move and transport the material.

[0061] The stepping base plate 1 of the present application uses a moving plate 12 to move along the track formed by the T-shaped bracket 11 to realize material transportation, avoiding the unstable and easy slipping phenomenon of the crawler conveying, and improving the transportation reliability and feeding efficiency. The stepping base plate 1 of the present application, the moving plate 12 is made of corrosion-resistant materials, which can avoid the problem of frequent maintenance and replacement of the base plate and short service life of the base plate caused by the easy corrosion of rubber materials such as crawlers, and can reduce production costs. The T-shaped bracket 11 forms a track to ensure the stability of the moving plate 12 during movement.

[0062] In this embodiment, the T-shaped brackets 11 are arranged at intervals along the length direction to form a track, wherein the length direction is the moving direction of the moving plate 12. The T-shaped brackets 11 are arranged at intervals, the number of the T-shaped brackets 11 can be reduced, the cost can be reduced, the formation of the track and the movement of the moving plate 12 are not affected, and the weight of the stepping base plate 1 can be reduced.

[0063] In the present embodiment, there are multiple T-shaped brackets 11, which are arranged in an array to form multiple tracks, one of which is formed by three T-shaped brackets 11 arranged in a row. The three T-shaped brackets 11 are arranged at intervals, and auxiliary rails 17 are arranged between them, which can improve the stability of the moving plate 12 during movement and ensure the consistency of the moving direction of the moving plate 12. The auxiliary rails 17 only play an auxiliary role, and the moving plate 12 mainly moves along the T-shaped brackets 11. The height and width of the auxiliary rails 17 are both smaller than the height and width of the track formed by the T-shaped brackets. During the movement of the moving plate 12, the moving plate 12 does not contact the auxiliary rails 17. In some other embodiments, a track can also be formed by two T-shaped brackets 11 arranged in a row, or four, five, and so on. There may be intervals between the T-shaped brackets 11, or there may be no intervals.

[0064] In this embodiment, a driving member 13 drives a moving plate 12, so that each moving plate 12 can move independently of other moving plates 12, and the moving plates 12 can be driven to move synchronously when conveying materials, and the materials can be conveyed for a certain distance. When the moving plates 12 need to be retracted and then conveyed, the moving plates 12 can be retracted separately, so that the materials will not be moved by the retraction of the moving plates 12, and efficient and fast material conveying can be achieved.

[0065] In the present embodiment, the base plate structure 10 includes a base plate frame 101 and a plurality of base plate support bars 102, wherein the base plate support bars 102 are fixed to the base plate frame 101 and support the T-shaped bracket 11. The base plate frame 101 is formed into a U-shape by a plurality of profiles, wherein the profiles may be hollow profiles or other profiles. The height of the two side frames of the base plate frame 101 is less than the height of one end connected to the driving member 13. In the present embodiment, the driving member 13 is connected to the base plate frame 101 through a profile, and the driving member 13 is hinged to the profile, and the profile is connected to the base plate frame 101. The profile and the base plate frame 101 may be fixedly connected by welding, pasting, etc. In some other embodiments, the driving member 13 may also be directly connected to the base plate frame 101, for example, directly hinged to the base plate frame 101. In some other embodiments, the driving member 13 can be connected to the bottom frame 101 in other ways, for example, each driving member 13 is individually connected to a connecting plate or a connecting block, and then the connecting plate or the connecting block is fixedly connected to the bottom frame 101. The fixed connection can also be achieved by welding, gluing, etc.

[0066] The bottom plate support bar 102 is arranged between the two frames of the bottom plate frame 101 to provide sufficient support for the T-shaped bracket 11. One end of the bottom plate support bar 102 is connected to one of the two frames of the bottom plate frame 101, and the other end is connected to the other of the two frames. Adjacent bottom plate support bars 102 can cover the area between the two frames of the bottom plate frame 101 without gaps, or can be arranged between the two frames of the bottom plate frame 101 at a distance from each other. Adjacent bottom plate support bars 102 can be arranged at equal intervals or at unequal intervals.

[0067] In this embodiment, see Figure 2 The stepping base plate 1 also includes an anti-corrosion base plate 16, which is arranged between the base plate structure 10 and the T-shaped bracket 11. The anti-corrosion base plate 16 is arranged between the base plate structure 10 and the T-shaped bracket 11, so that the material can fall from the gap between the moving plates 12 and fall onto the anti-corrosion base plate 16, thereby avoiding the scattering of the material. The anti-corrosion base plate 16 can be a whole plate laid on the base plate support bar 102, or a plurality of small plates laid on the base plate support bar 102. The anti-corrosion base plate 16 can be fixed to the base plate support bar 102, or fixed to the base plate frame 101. The anti-corrosion base plate 16 is made of corrosion-resistant material, such as stainless steel or polytetrafluoroethylene.

[0068] In this embodiment, the driving member 13 is a hydraulic cylinder, which includes a cylinder body 130 and a hydraulic rod 131, wherein the cylinder body 130 is connected to the base frame 101, and the cylinder body 130 is connected to the base frame 101 through a profile, and the cylinder body 130 and the profile are hingedly connected, and the profile is connected to the base frame 101. One end of the hydraulic rod 131 extends into the cylinder body 130, and the other end is connected to the moving plate 12. The hydraulic cylinder 13 drives the moving plate 12 to move, and has a simple structure, sufficient and controllable driving force, and can meet the actual needs of material feeding.

[0069] In this embodiment, the stepping base plate 1 further includes supporting feet 14, which are arranged on the base plate structure 10 to support the entire device. The number of the supporting feet 14 is at least four, can be six, or can be more.

[0070] like Figure 5 and Figure 7As shown, the T-shaped bracket 11 includes a first part 111 and a second part 112. The cross section of the T-shaped bracket 11 is in a "T" shape, wherein the cross section is a plane of the T-shaped bracket 11 perpendicular to the moving direction of the movable plate 12. The projection of the first part 111 on the cross section is connected to the projection of the second part 112 on the cross section without overlapping. The projection of the first part 111 has a first dimension L1 at one end close to the second part 112, and the projection of the second part 112 has a second dimension L2 at one end close to the first part 111. The first dimension L1 is greater than the second dimension L2. The second part 112 of the T-shaped bracket 11 is connected to the base plate structure 10, and the first part 111 supports the movable plate 12.

[0071] The T-shaped bracket 11 uses a larger first part 111 to support the movable plate 12, while the smaller second part 112 is connected to the base plate structure 10, which can make the movement of the movable plate 12 smooth and stable, and can increase the contact area between the T-shaped bracket 11 and the movable plate 12, so that the movable plate 12 can move more stably along the T-shaped bracket 11.

[0072] In this embodiment, the first portion 111 of the T-shaped bracket 11 has a first surface 113 away from the second portion 112, and a wear-resistant plate 15 is provided on the first surface 113. The wear-resistant plate 15 is provided on the surface of the T-shaped bracket 11 in contact with the moving plate 12 to increase the service life of the T-shaped bracket 11. The wear-resistant plate 15 can be made of a polymer or other wear-resistant materials.

[0073] In this embodiment, a fixing hole 1110 is provided on the first surface 113 of the T-shaped bracket 11, and the fixing hole 1110 is used to fix the wear-resistant plate 15. Of course, the wear-resistant plate 15 can also be fixed to the first surface 113 in other ways, such as pasting, clamping, etc. One T-shaped bracket 11 can be fixed with one wear-resistant plate 15, or multiple wear-resistant plates 15 can be fixed. In this embodiment, two wear-resistant plates 15 are fixed on one T-shaped bracket 11.

[0074] like Figures 1 to 3 , Figure 6 and Figure 7As shown, the movable plate 12 includes a plate body 121, two plate walls 122, 123 and two plate edges 124, 125. The plate body 121 is in a strip shape. The two plate walls 122, 123 are respectively connected to the two sides of the plate body 121, and extend in the same direction perpendicular to the plate body 121 to form two extension ends. The two plate edges 124, 125 are respectively connected to the two extension sections of the two plate walls 122, 123, and extend relatively in a direction parallel to the plate body 121 to form a notch 126. The movable plate 12 is in a strip shape and is laid along the track for completing material feeding. The movable plate 12 adopts a cross-sectional shape similar to a "C" shape, which enables the movable plate 12 to be stable and fast when moving along the track formed by the T-shaped bracket 11, thereby completing rapid material feeding.

[0075] In this embodiment, the plate body 121, plate walls 122, 123 and plate edges 124, 125 of the movable plate 12 are integrally formed. In some other embodiments, the plate body 121, plate walls 122, 123 and plate edges 124, 125 can also be welded together after being processed separately. The connection between the plate body 121 and the plate walls 122, 123 is arc-shaped, and the connection between the plate wall 122 and the plate edge 124 and the plate wall 123 and the plate edge 125 is also arc-shaped.

[0076] In this embodiment, the plate 121 contacts the material. Figure 7 The movable plate 12 is slidably connected to the T-shaped bracket 11 through the space formed by the plate body 121, the plate walls 122, 123 and the plate edges 124, 125, and a part of the T-shaped bracket 11 extends out of the movable plate 12 through the notch 126. In this way, it can be ensured that the movable plate 12 is always stably stuck in the T-shaped bracket 11 during the movement. Furthermore, the first part 111 and the wear-resistant plate 15 of the T-shaped bracket 11 are located in the space formed by the plate body 121, the plate walls 122, 123 and the plate edges 124, 125, and the second part 112 of the T-shaped bracket 11 extends out of the notch 126 of the movable plate 12. The size of the notch 126 of the movable plate 12 is larger than the second size L2 of the T-shaped bracket 11, but smaller than the second size L2 of the T-shaped bracket 11, so that it can be ensured that the movable plate 12 will not be separated from the T-shaped bracket 11 during the movement, thereby improving the reliability of the use of the stepping base plate 1.

[0077] In this embodiment, see Figure 7 When the movable plate 12 moves, the plate body 121 contacts the wear-resistant plate 15, and there are gaps between the two plate walls 122, 123, and the two plate edges 124, 125 of the movable plate 12 and the T-shaped bracket. In this way, the movable plate 12 can move smoothly, and the T-shaped bracket only contacts the movable plate 12 through the wear-resistant plate, and the service life of the T-shaped bracket is long.

[0078] In this embodiment, see Figures 1 to 3The end surface of the moving plate 12 away from the driving member 13 (hydraulic cylinder 13) is inclined. The end surface is inclined from the plate body 121 to the plate edges 124 and 125. In the length direction of the moving plate 12, the length of the plate body 121 is less than the length of the two plate edges 124 and 125, and the length of the two plate walls 122 and 123 gradually increases from the plate body 121 to the plate edges 124 and 125. The end of the moving plate 12 away from the hydraulic cylinder 13 is inclined, which is conducive to the separation of materials from the stepping bottom plate 1.

[0079] like Figure 4 As shown, the hydraulic cylinder 13 is connected to one end of the surface of the plate body 121 that contacts the material. A fixed plate 132 is provided at one end of the surface of the plate body 121 that contacts the material, and two fixed ears 133 are provided on the fixed plate 132. A fixed head 134 is provided at the end of the hydraulic rod 131, and the fixed head 134 is pivotally connected to the two fixed ears 133. The hydraulic rod 131 pushes or pulls the fixed plate 132 to move, thereby realizing the movement of the movable plate 12. The movable plate 12 and the fixed plate 132 can be riveted, bonded, or threaded, or other fixing methods can be used.

[0080] It should be noted that since the hydraulic rod 131 is connected to the moving plate 12, Figure 2 and Figure 3 After the movable plate 12 is removed, the hydraulic rod 131 , the fixed plate 132 , the fixed ears 133 and the fixed heads 134 are all suspended on the anti-corrosion bottom plate 16 .

[0081] The material of the present application is a corrosive material, such as corn stalks. The stepping base plate 1 of the present application can also transport other materials. In addition, the stepping base plate of the present application can also store materials.

[0082] The present application only uses corn stalks as an example for illustration, and the stepping base plate 1 of the present application can transport other materials that need to be transported except corn stalks.

[0083] The present application also provides a material conveyor, wherein the bottom plate of the material conveyor adopts the above-mentioned stepping bottom plate 1. The material conveyor of the present application adopts a corrosion-resistant stepping bottom plate, avoiding the problem of easy corrosion caused by the bottom plate made of rubber materials such as crawler tracks. At the same time, the stepping bottom plate 1 of the conveyor of the present application adopts a driving member to drive the moving plate to move on the track to realize the stepping conveying of materials, which can provide a more stable driving power than when using crawler tracks for conveying, and can improve the feeding efficiency and conveying effect while being corrosion-resistant.

[0084] The above is a detailed description of several exemplary embodiments of the stepping base plate and the material conveyor proposed in the present application. The material conveying method proposed in the present application will be described exemplarily below.

[0085] like Figures 1 to 7As shown, the present application also provides a material conveying method, wherein the material conveyor adopts the above material conveyor, and the conveying method comprises the following steps:

[0086] Step S1: The moving plate 12 is arranged at a position close to the driving member 13, and the material is placed on the moving plate 12 of the stepping base plate 1;

[0087] Step S2: the driving member 13 drives the moving plate 12 to move synchronously in a direction away from the driving member 13 , thereby transporting the material in a direction away from the driving member 13 ;

[0088] Step S3: the driving member 13 drives the movable plates 12 to move towards the driving member 13 one by one or at intervals until all the movable plates 12 return to the position close to the driving member 13;

[0089] Step S4: Repeat steps S2 and S3 in a loop until the material is transported to the designated location.

[0090] The material conveying method of the present application uses a synchronous drive method to convey materials, which has high conveying efficiency and large conveying force, and can convey more materials; and the position of the moving plate 12 is restored one by one or at intervals, which can prevent the material from being moved by the friction of the moving plate 12. The following takes corn stalks as an example to describe the conveying process in detail:

[0091] Implementation method 1:

[0092] Put the chopped straw with high humidity as material into the stepping bottom plate 1 from the upper part of the stepping bottom plate 1. Since the chopped straw itself is easy to gather, it will form a mass on the stepping bottom plate 1. Therefore, when the stepping bottom plate 1 is not operating, the chopped straw will not flow. At this time, the stepping bottom plate 1 of the present application can store materials.

[0093] When it is necessary to convey materials, the hydraulic cylinder 13 is started, and the hydraulic cylinder 13 pushes the moving plate 12 to continuously move along the T-shaped bracket 11 and the wear-resistant plate 15. During the conveying process, the moving plate 12 moves away from the hydraulic cylinder 13, and all the moving plates 12 move away from the hydraulic cylinder 13 synchronously, thereby driving the materials to move in the discharge direction. Due to the large static friction between the materials and the moving plates 12, the materials will move away from the hydraulic cylinder 13 along with all the moving plates 12.

[0094] After moving into position, the hydraulic cylinder 13 is controlled to pull the moving plates 12 one by one to move in the direction close to the hydraulic cylinder 13. Because the static friction between a single moving plate 12 and the material is much smaller than the sum of the static friction between other moving plates 12 and the material, the material will maintain its original position while the moving plates 12 move one by one in the direction close to the hydraulic cylinder 13, and will not move in the direction close to the hydraulic cylinder 13. After the moving plates 12 move one by one in the direction close to the hydraulic cylinder 13, all the moving plates 12 can move together in the direction away from the hydraulic cylinder 13, driving the material to continue to move in the direction of discharging. Due to the static friction, the material will always move in the direction of discharging as the moving plates 12 continue to push.

[0095] Implementation method 2:

[0096] Put the chopped straw with high humidity into the stepping bottom plate 1 from the upper part of the stepping bottom plate 1 as the material. Since the chopped straw itself is easy to gather, it will form a mass on the stepping bottom plate 1, so that when the stepping bottom plate 1 is not operating, the chopped straw will not flow.

[0097] The hydraulic cylinder 13 is started, and the hydraulic cylinder 13 pushes the moving plate 12 to continuously move along the T-shaped bracket 11 and the wear-resistant plate 15. During the feeding process, the moving plate 12 moves away from the hydraulic cylinder 13, and all the moving plates 12 move away from the hydraulic cylinder 13 synchronously, thereby driving the material to move in the discharge direction. Due to the large static friction between the material and the moving plate 12, the material will move away from the hydraulic cylinder 13 along with all the moving plates 12.

[0098] After moving into position, the hydraulic cylinder 13 is controlled to pull the moving plate 12 to move in the direction close to the hydraulic cylinder 13 at intervals. Because the static friction between a single moving plate 12 and the material is much smaller than the sum of the static friction between other moving plates 12 and the material, the material will maintain its original position during the process of the moving plate 12 moving in the direction close to the hydraulic cylinder 13 at intervals, and will not move in the direction close to the hydraulic cylinder 13. After the moving plate 12 moves in the direction close to the hydraulic cylinder 13 at intervals, all the moving plates 12 can move together in the direction away from the hydraulic cylinder 13, driving the material to continue to move in the direction of discharging. Due to the static friction, the material will always move in the direction of discharging as the moving plate 12 continues to push.

[0099] In the above two embodiments, the moving speed of the moving plate 12 can be adjusted and controlled by controlling the hydraulic cylinder 13, so that the feeding speed can be adjusted and controlled.

[0100] Through the above-mentioned material conveying method of the present application, it can be concluded that the stepping base plate 1 of the present application uses a T-shaped bracket 11 to form a track, and uses a moving plate 12 made of corrosion-resistant material to move to realize the stepping conveying of materials, thereby avoiding the problem that rubber materials such as crawlers are easily corroded. The stepping base plate 1 proposed in the present application uses a driving member 13 to drive the moving plate 12 to move on the track to realize the stepping conveying of materials, which can provide a more stable driving power than when using crawler conveying, and can improve the material conveying efficiency while being corrosion-resistant.

[0101] In summary, the stepping base plate 1 proposed in the present application includes a base plate structure 10, at least two T-shaped brackets 11, at least two movable plates 12 and at least two driving members 13. At least two T-shaped brackets 11 are distributed in an array on the base plate structure 10, and the T-shaped brackets 11 constitute at least two tracks. At least two movable plates 12 are arranged on the T-shaped brackets 11 and can move along the tracks, and the movable plates 12 are made of corrosion-resistant materials. The movable plates 12 are mainly used for moving and conveying materials, and are made of corrosion-resistant materials, so that the entire stepping base plate 1 can be corrosion-resistant. At least two driving members 13 are connected to the base plate structure 10, and drive the movable plates 12 to move. The driving member 13 drives the movable plates 12, which can provide a larger stable driving force to achieve stable material feeding.

[0102] The material conveyor proposed in the present application includes the above-mentioned stepping base plate 1. The problem of easy corrosion caused by the base plate made of rubber materials such as crawler tracks is avoided. At the same time, the stepping base plate 1 of the conveyor of the present application adopts a driving member to drive the moving plate to move on the track to realize the stepping conveying of materials, which can provide a more stable driving power than when using crawler tracks for conveying, and can improve the feeding efficiency and conveying effect while being corrosion-resistant.

[0103] The material conveying method proposed in the present application sets the moving plate 12 at a position close to the driving member 13, and places the material on the moving plate 12 of the stepping base plate 1; the driving member 13 drives the moving plate 12 to synchronously move in a direction away from the driving member 13, thereby conveying the material in a direction away from the driving member 13; the driving member 13 drives the moving plate 12 to move in a direction close to the driving member 13 one by one or at intervals until all the moving plates 12 return to a position close to the driving member 13; the cycle is repeated until the material is conveyed to the designated position. The material conveying method of the present application uses a synchronous drive method for the moving plate 12 to realize material conveying, and has high conveying efficiency and sufficient conveying force; and restoring the position of the moving plate 12 one by one or at intervals can prevent the material from moving due to the friction of the moving plate 12, thereby realizing continuous and efficient material feeding.
