Description

Technical Field

[0001] The present application relates to the technical field of teaching demonstration tools, and more specifically, to a teaching mold for large tree transplantation training. Background Art

[0002] Large trees generally refer to deciduous trees with a diameter at breast height (DBH) of 20 cm or more and evergreen trees with a DBH of 15 cm or more. Transplanting trees of this size is called large tree transplanting, sometimes also referred to as transplanting mature or adult trees. Large tree transplanting is a common practice in urban landscaping and greening projects. Through large tree transplanting, the plant configuration and spatial structure of urban green spaces can be optimized in a short period of time, meeting the greening and beautification requirements of key and large-scale municipal projects in a timely manner and maximizing the ecological and landscape benefits of urban green spaces. It is an important means and technical measure frequently used in modern urban landscaping and greening projects.

[0003] At present, in the teaching of gardening majors, technical training on large tree transplantation mostly adopts the method of theoretical explanation and picture display, lacking intuitive and vivid operation demonstration models, especially the binding and hoisting process of large tree soil balls. Due to its complexity and technicality, students often find it difficult to understand and master it with just text and pictures. The problem with the existing technology is that there is a lack of a large tree soil ball binding and hoisting model that can simulate real scenes and is easy for students to operate and practice.

[0004] In view of this, we propose a teaching mold for large tree transplantation training. Summary of the Invention

[0051] Beneficial effects: One or more technical solutions provided in the technical solution of the present application have at least the following technical effects or advantages: 1. The real shape of a big tree is simulated by the big tree model structure, and the soil ball model in the big tree model structure is tied by the soil ball strap to simulate the real tying process, and then the two half-clamping frames in the lifting assembly are assembled together, so that the lifting assembly can be clamped and fixed on the trunk model, and in the process of assembling the two half-clamping frames together, the retracted first air cylinder assembly continuously injects the gas inside it into the second air cylinder assembly through the guide pipe, so that the second air cylinder assembly drives the clamping head assembly connected to its free end to apply additional clamping force to the side wall of the trunk model during the continuous extension process, thereby realizing double fixation of the big tree model structure, further enhancing the stability of the lifting assembly fixation, and effectively reducing the risk of slippage of the big tree model structure during the lifting process.

[0052] 2. The second air cylinder assembly continuously extends and drives the clamp assembly connected to the free end to apply additional clamping force to the side wall of the trunk model, while the first tooth groove in the clamp assembly engages with the transmission gear in the forcing unit. During the tilting hoisting process of the large tree model structure, when the large tree model structure slips due to the loose fixation of the two half-clamping frames in the hoisting assembly, the sliding trunk model drives the clamp assembly close to its side wall to move, so that the movable clamp assembly drives the insulating slide in the forcing member to slide through the transmission gear, drives the strip trigger piece to contact the trigger spring piece, and triggers the alarm in the alarm mechanism to turn on, and reminds the operator to stay away from the hoisting area in time, thereby improving the safety of the operation.

[0053] 3. When the insulating slide slips, it not only triggers the alarm mechanism to open, but also enables the synchronous ejector to puncture the separation diaphragm in the pressurizing part, so that the liquid part contacts the water-disintegrating particles and reacts rapidly to release a large amount of gas. The gas is then quickly injected into the second gas cylinder assembly through the pipe fitting, so that the chuck assembly is further pressed against the surface of the tree trunk model, increasing the resistance that needs to be overcome during the sliding process of the tree model structure, effectively slowing down the sliding speed of the tree model structure, and realizing active braking of the tree model structure that is in the sliding process. After receiving the alarm signal from the alarm mechanism, the operator has more sufficient time to react and escape, thereby ensuring people's safety during the simulated operation of tree transplanting.

[0075] The alarm mechanism includes an alarm 211, a strip-shaped trigger piece 217 and a trigger spring piece 218 arranged opposite to each other, wherein the alarm 211 is preferably an audible and visual alarm;

[0076] The strip-shaped trigger piece 217 is connected to the insulating slide 216. The side surface of the strip-shaped trigger piece 217 is flush with the side surface of the insulating slide 216. When the elastic reset member is in the initial relaxed state, the trigger spring piece 218 is located above the strip-shaped trigger piece 217.

The chuck assembly includes an inverted L-shaped frame 215 and a third spring 227. The side wall of the inverted L-shaped frame 215 is slidably connected to a longitudinal seat 212.

[0088] The top of the vertical seat 212 is connected to a gain clamping seat 205, and an anti-skid pad is connected to the gain clamping seat 205. When the gain clamping seat 205 applies a holding force to the side wall surface of the trunk model 104, the anti-skid pad connected to the gain clamping seat 205 increases the friction between the surface of the trunk model 104 and the gain clamping seat 205.

During the tilting hoisting process of the large tree model structure, when the two half-clamping frames 201 in the hoisting assembly are not firmly fixed, causing the large tree model structure to slip, the sliding trunk model 104 drives the clamp assembly close to its side wall to move, so that the movable clamp assembly drives the insulating slide 216 in the forcing member to slide through the transmission gear 219, drives the strip trigger piece 217 to contact the trigger spring piece 218, and triggers the alarm 211 in the alarm mechanism to turn on, and reminds the operator to stay away from the hoisting area in time, thereby improving the safety of the operation.
