The big tree model structure comprises a trunk model, and the hoisting assembly is detachably installed and fixed on the trunk model. In the process of assembling the two semi-hooping frames together, the retracted first inflator assembly continuously injects gas in the first inflator assembly into the second inflator assembly through the flow guide pipeline, so that the gas in the second inflator assembly is continuously injected into the second inflator assembly in the continuous extension process; when a large tree model structure is obliquely hoisted, a chuck assembly connected with the free end of the hoisting assembly is driven to apply additional clamping force to the side wall of the tree trunk model, meanwhile, a first tooth groove in the chuck assembly is meshed with a transmission gear in a forcing unit, and in the inclined hoisting process of the large tree model structure, when the large tree model structure slides due to the fact that the hoisting assembly is not firmly fixed, the large tree model structure cannot be firmly fixed. The sliding trunk model drives the chuck assembly tightly attached to the side wall of the trunk model to move.

Description

Technical Field

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

[0016] Beneficial effects: One or more of the technical solutions provided in the technical solution of this application have at least the following technical effects or advantages: 1. By simulating the shape of a real big tree with the big tree model structure, and then binding the soil ball model in the big tree model structure with the soil ball binding strap to simulate the real binding process, and then assembling the two semi-clamping frames in the lifting assembly together, so that the lifting assembly can be tightly fixed on the tree trunk model.

And during the inclined lifting process of the big tree model structure, when the big tree model structure slips due to the insecure fixation of the two semi-clamping frames in the lifting assembly, the sliding tree trunk model drives the chuck assembly attached to its side wall to move. During the process of the moving chuck assembly driving the insulating sliding seat in the actuating member to slide, it drives the strip-shaped trigger piece to contact the trigger piece, and triggers the alarm in the alarm mechanism to turn on, and reminds the operator to stay away from the lifting area in time, improving the safety of the operation.

[0018] 3. When the insulating sliding seat slips, it can not only trigger the opening of the alarm mechanism, but also enable the synchronous ejector pin to pierce the partition diaphragm in the pressurizing component, so that the liquid part contacts the water-disintegrable particles and reacts to quickly release a large amount of gas. The gas is then quickly injected into the second air cylinder assembly through the pipeline component, so that the chuck assembly is further tightly pressed on the surface of the tree trunk model, increasing the resistance required to overcome during the slipping process of the tree model structure, effectively slowing down the slipping speed of the tree model structure, and realizing the active braking treatment of the tree model structure during the slipping process. After the operator receives the alarm signal sent by the alarm mechanism, there is more sufficient reaction and escape time, ensuring the safety of people during the simulated operation of tree transplantation.

The reinforcing component further includes an outer shell 202 connected to the side wall of the semi-clamping frame 201, and a lifting ring 203 is connected to the side wall of the outer shell 202; The plug column cylinder shell 209 is connected to the inner cavity of the outer shell 202, and one end of the airtight column 214 near the inner arc-shaped clamping plate 210 penetrates through the side wall of the semi-clamping frame 201 and is connected to the inner arc-shaped clamping plate 210 located in the inner cavity of the semi-clamping frame 201; The mating cylinder 204 is connected to the outer shell 202; A horizontal straight groove is opened at the top end of the outer shell 202, and the bottom end of the inverted L-shaped frame body 215 passes through the horizontal straight groove and extends into the inner cavity of the outer shell 202; The inverted L-shaped frame body 215 is horizontally slidably connected in the horizontal straight groove, and one end of the plug rod away from the passive plug seat 213 extends into the inner cavity of the outer shell 202 and is connected to the side wall of the longitudinal seat body 212; The top end of the longitudinal seat body 212 extends out of the horizontal straight groove and is connected to the gain clamping seat 205; The insulating sliding seat 216 is vertically slidably connected in the inner cavity of the outer shell 202, and the transmission gear 219 is rotatably connected in the inner cavity of the outer shell 202; A reserved hole for the upper cylinder 221 to pass through is opened at the top end of the outer shell 202, and the upper cylinder 221 passes through the reserved hole and extends into the inner cavity of the outer shell 202; The top end cover 222 is connected to the top end of the outer shell 202 and is hermetically connected to the opening at the end of the reserved hole; The alarm 211 is connected to the side wall of the outer shell 202; The fixed end of the trigger shrapnel 218 is connected to the side wall of the semi-clamping frame 201, and the semi-clamping frame 201 is made of insulating material.

[0041] When the insulating sliding seat 216 slips, it can not only trigger the opening of the alarm mechanism, but also cause the synchronous ejector pin 220 to pierce the partition diaphragm 224 in the pressurizing member, so that the liquid part 226 contacts the water-disintegrating particles 223 to react and rapidly release a large amount of gas. The gas is then quickly injected into the second air cylinder assembly through the pipeline member, so that the chuck assembly is further tightly pressed on the surface of the tree trunk model 104, increasing the resistance required to overcome during the sliding process of the tree model structure, effectively slowing down the sliding speed of the tree model structure, and realizing the active braking treatment of the tree model structure during the sliding process. After the operator receives the alarm signal from the alarm mechanism, there is more sufficient reaction and escape time, ensuring the safety of people during the simulated operation of tree transplantation.

[0042] Referring to Figure 1 and Figure 4 , the embodiment of the present application provides a teaching mold for tree transplantation training. The tree model structure further includes a soil ball base 102, a soil ball binding band 103, and a soil ball model 101 connected to the bottom end of the tree trunk model 104; A positioning insertion rod is further connected to the top end of the soil ball base 102; The bottom of the soil ball model 101 is provided with a positioning bottom groove into which the positioning insertion rod can be movably inserted.

[0043] By simulating the real shape of the tree through the tree model structure, and then binding the soil ball model 101 in the tree model structure with the soil ball binding band 103, the real binding process of the tree soil ball is simulated.

[0044] After the positioning insertion rod is inserted into the positioning bottom groove at the bottom of the soil ball model 101, while the soil ball base 102 supports the bottom of the soil ball model 101, it can also lift the bottom of the soil ball model 101 through the soil ball base 102, facilitating the students to pass through the bottom of the soil ball model 101 when binding the soil ball model 101 with the soil ball binding band 103.
