[0028] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] As shown in the figure, a display teaching aid for children's agricultural research and study includes: a display stand, a driving mechanism arranged inside the display stand, and a plurality of display mechanisms connected to the driving mechanism;

[0030] It should be noted that the driving mechanism is arranged at the bottom of the display stand, and the display mechanism is arranged above the display stand. The driving mechanism is used to drive the display mechanism for display.

[0031] The driving mechanism includes: a sprocket group, and a driving member arranged at the bottom of the sprocket group; the display mechanism is fixedly connected to the sprocket group, and the sprocket group is used to drive the display mechanism to perform cyclic display in the display slot;

[0032] In a preferred embodiment of the utility model, the driving component includes: a driving motor, a turntable arranged on one side of the driving motor, and a groove wheel arranged on one side of the turntable; a third sprocket is arranged on the driving motor, and a fourth sprocket is arranged on the turntable, and the third sprocket and the fourth sprocket are also connected by a chain.

[0033] In a preferred embodiment of the utility model, a plurality of limiting grooves and a plurality of shifting grooves are provided on the groove wheel, and the shifting grooves and the limiting grooves are arranged alternately.

[0034] In a preferred embodiment of the utility model, a toggle plate is fixedly connected to the bottom of the rotating plate, a toggle shaft is arranged on the toggle plate, and the toggle shaft is meshed with the toggle groove.

[0035] In a preferred embodiment of the utility model, the driving mechanism further comprises a driving housing, the driving housing is fixedly connected to the display table, and the driving motor is fixedly connected in the driving housing.

[0036] The third sprocket is connected to the driving housing and the fourth sprocket is connected to the driving housing. The third sprocket is connected to the fourth sprocket by the chain. The third sprocket is connected to the fourth sprocket by the chain. The fourth sprocket is connected to the third sprocket by the chain.

[0037] When the driving motor rotates, the turntable is driven to rotate through the third sprocket and the fourth sprocket, and then the toggle plate is driven to rotate. The toggle shaft on the toggle plate first enters the toggle groove, and as the toggle plate rotates, the toggle shaft is driven to rotate, and then gradually penetrates into the toggle groove through the toggle shaft, and then withdraws from the toggle groove. As the toggle shaft enters and withdraws from the toggle groove, the groove wheel is pushed to rotate. When the toggle shaft is completely withdrawn, the semicircular turntable rotates to the limit groove on the groove wheel, and because the turntable is semicircular and the limit groove is quarter-circular, the turntable does not push the groove wheel to rotate, but because the turntable is located at the limit groove, the groove wheel cannot rotate. Therefore, when the limit groove of the groove wheel is engaged with the turntable, the groove wheel stops moving, and when the toggle groove of the groove wheel is engaged with the toggle shaft of the toggle plate, the groove wheel rotates.

[0038] Then, as the turntable rotates, the toggle shaft on the toggle plate engages with the toggle groove on the groove wheel, driving the groove wheel to rotate until the toggle shaft disengages from the toggle groove, and the turntable engages with the limit groove, at which time the groove wheel stops rotating, thereby performing reciprocating motion and causing the groove wheel to perform intermittent motion.

[0039] In a preferred embodiment of the utility model, the sprocket set includes a first sprocket and a second sprocket, and the first sprocket and the second sprocket are connected by a chain.

[0040] In a preferred embodiment of the present invention, the first sprocket and the second sprocket are both placed horizontally.

[0041] It should be noted that the first sprocket is fixedly connected to the groove wheel and is rotatably connected to the drive housing, the second sprocket is rotatably connected to the drive housing, and the display mechanism is fixedly connected to the chain of the sprocket set.

[0042] When in use, the driving motor drives the groove wheel to make intermittent motion, thereby driving the first sprocket to rotate, thereby driving the rotation of the chain to drive the display mechanism on the chain to be displayed on the display stand.

[0043] The display stand includes: a display table, a display shell arranged on the top of the display table; a plurality of display slots are provided on both sides of the display shell, and the display slots are used to display relevant contents of farming culture; a driving mechanism is arranged at the bottom of the display table;

[0044] In a preferred embodiment of the utility model, a plurality of screens are arranged on the outside of the display shell, and a partition block is fixedly connected in the middle of the display table.

[0045] It should be noted that the display shell and the dividing block are fixedly connected on the display table, the driving mechanism is arranged under the display table, the chain of the driving mechanism is elliptical, the dividing block is arranged in the middle position of the chain, and the size of the dividing block interferes with the movement of the display mechanism, grooves are provided on both sides of the dividing block, and lights are provided on the inner side of the grooves. The lights are always on and the light shines on the position of the display mechanism, and the display shell is provided on the outer side of the display mechanism. Therefore, the entire display table is composed of dividing blocks, display mechanisms and display shells from the inside to the outside, and they are arranged in a surrounding shape, that is, the display mechanism surrounds the outer side of the dividing block, the display shell surrounds the outer side of the display mechanism, and a display groove is provided on the display shell. In the absence of a display mechanism, the groove on the dividing block can be fully seen through the display groove, and a screen is fixedly connected to the positions around the display shell where no display groove is provided, and the screen can display farming related information through the control motherboard.

[0046] The display mechanism comprises: a fixed block, a display frame arranged on the fixed block, and a fixed buckle slidably connected with the display frame; the fixed buckle is used to fix the display frame, and the fixed block is fixedly connected with the sprocket group.

[0047] In a preferred embodiment of the utility model, the display rack includes a bottom plate and a rotating shaft rotatably connected to the bottom plate; a frame is arranged on the bottom plate, a moving rod is slidably connected to the frame, and a torsion spring is arranged in the rotating shaft.

[0048] It should be noted that the fixed block includes a card slot and a card block. The card slot is a hexagonal slot with a hollow middle, and the card block is a hexagonal column. The size of the card slot is the same as that of the card block, and the card block can just be placed in the card slot, and the card block and the card slot are both regular hexagonal. When the card block is placed in the card slot, the card block is fixed, the card slot is fixedly connected to the chain of the sprocket set, and the base plate is fixedly connected to the card block. The base plate can be fixed to the chain through the card block, and a fixed slot is provided on the base plate. When conducting agricultural research and study activities for children, agricultural-related items can be connected and placed on the base plate through the fixed slot, and the relevance of farming and items can be introduced. At the same time, the use of the item can be introduced and played through the screen, so that children can understand it more clearly and intuitively.

[0049] The frame and the rotating shaft are both arranged on one side of the bottom plate close to the dividing block. The frame is vertically and fixedly connected to the bottom plate. The rotating shaft is rotatably connected to the bottom plate, and a torsion spring is arranged on the inner side of the rotating shaft. The inner side of the frame is slidably connected to the moving rod, that is, the moving rod can move up and down on the frame. When the farming-related items are clamped on the bottom plate, the name of the item is printed on paper, and one end of the paper is fixed on the rotating shaft and wound around the rotating shaft. After the winding is completed, the other end is fixed on the moving rod. When in use, the moving rod is pulled upward and fixed to the top of the frame using a fixing buckle, so that the paper is opened. , the effect of displaying the name of the item is achieved, and when one of the display racks is rotated to the slot of the dividing block, children watching from the outside can only see what is displayed on the display rack at the slot through the display slot of the display shell, and the light in the slot shines through the paper, highlighting the name of the item, so that children can understand what the item is at first glance. At the same time, the use of the item is played on the adjacent screen, which further deepens children's understanding of farming and farming items. When not in use, the moving rod is loosened through the fixing buckle, the torsion spring recovers its deformation, and drives the rotating shaft to rotate in the opposite direction to rewind the paper onto the rotating shaft.

[0050] The fixing buckle is arranged in an I-shape, and a through hole is provided in the middle position of the top of the frame. The fixing buckle is slidably connected to the through hole. A rectangular groove is provided on the moving rod at a position on the same axis as the through hole. The length of the rectangular groove can allow the fixing buckle to pass through. When in use, the moving rod moves up to a position that fits the top of the frame, so that the fixing buckle passes through the rectangular groove and the fixing buckle is rotated 90°. Since the rectangular groove is arranged in a rectangular shape, its length and width are not equal. After rotating 90°, the length of the fixing buckle is parallel to the width of the rectangular groove, and the length of the long is greater than the length of the wide, so that the fixing buckle cannot pass through the rectangular groove, thereby fixing the moving rod. After use, you only need to rotate the fixing hole 90° again.

[0051] When the utility model is used to demonstrate farming-related things to children, it is only necessary to turn on the drive click, thereby driving the follower wheel to rotate intermittently, and then driving the chain to rotate, and driving the farming-related items on the display rack to be displayed at a time, and introducing them through the adjacent screen, so as to complete the research and education of children, and when demonstrating, related items can be placed on the floor according to the entire farming process, so that children can understand the entire farming process or its development history or the introduction of various farming supplies in a more systematic way.

[0052] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model.
