Description

Technical Field

[0001] The utility model belongs to the technical field of micro-tillage machines, and in particular relates to a micro-tillage machine special for greenhouse vegetables. Background Art

[0002] In modern agriculture, especially in the intensive cultivation of greenhouse vegetables, micro-tillers are important mechanized tools whose performance and efficiency directly impact the growth environment and yield of crops. However, the micro-tillers currently widely used in greenhouses have limitations in terms of blade spacing adjustment and tillage depth control.

[0003] Traditional tillers often feature fixed blade spacing or require complex tool adjustment, limiting their applicability across diverse soil types and cropping patterns while also increasing operator workload and time. In greenhouses, where the space is relatively closed and crops are densely planted, the demands for precision and efficiency are even higher, making it difficult for traditional tillers to adapt quickly to this changing operating environment.

[0004] Adjusting tillage depth is also a major challenge for traditional tillers. Most require downtime, disassembly, or reassembly to adjust tillage depth, which not only impacts operational continuity but also reduces efficiency. In greenhouse vegetable cultivation, crops at different growth stages require varying degrees of soil looseness, making frequent adjustment of tillage depth crucial for optimal crop quality.

[0005] To overcome these technical challenges, some micro-tillage machines with adjustable blade spacing and tillage depth have emerged in recent years. However, these devices are often complex, costly, and in practice, the adjustment process is not smooth, which has hindered their widespread application. Therefore, the development of a micro-tillage machine specifically for greenhouse vegetables with a simple structure, convenient operation, and the ability to quickly adjust blade spacing and tillage depth has become an urgent problem to be solved in the field of agricultural mechanization. Utility Model Content

[0006] In view of the above problems, the purpose of the present utility model is to provide a micro-tillage machine specially designed for greenhouse vegetable sheds, so as to solve the problems that most of the micro-tillage machines in existing greenhouse vegetable sheds have difficulties in adjusting the blade spacing and controlling the tillage depth.

[0007] The control wheel that is located at the bottom of the vehicle frame is the control wheel that is located at the top of the vehicle frame, and the control wheel shaft is connected with the control wheel shaft of the vehicle frame by rotating the vehicle frame.

[0008] The beneficial effects of the utility model are as follows: through the structural design of the split blade and the scissor-type connecting rod mechanism, the blade spacing of the greenhouse vegetable shed micro-tillage machine can be quickly adjusted; at the same time, combined with the design of the rotatable and lockable rotating arm, the tillage depth can be easily adjusted, which significantly improves the convenience of operation, tillage efficiency and planting benefits.

[0009] In order to effectively adjust the use height of the adjustable split blade assembly;

[0010] As a further improvement of the above technical solution: the adjustment bracket is an arc-shaped plate structure, and the multiple through holes opened on the adjustment bracket are arranged around the axis of the output shaft of the reduction motor.

[0011] The beneficial effect of this improvement is that when the rotating arm rotates around the axis of the output shaft of the reduction motor, the operator can insert a bolt into the through hole of the adjustment bracket opposite to the through hole at the top of the connecting arm, thereby realizing quick and effective adjustment of the use height of the adjustable split blade assembly.

[0012] In order to ensure the stability of the chain drive mechanism;

[0013] As a further improvement of the above technical solution: the driving sprocket in the chain transmission mechanism is installed on the output shaft of the reduction motor, the driven sprocket in the chain transmission mechanism is installed on one end of the main shaft, and the main shaft is rotatably installed on the rotating arm.

[0014] The beneficial effect of this improvement is that the chain transmission mechanism can stably transmit the power of the reduction motor to the tool holder power shaft.

[0015] In order to ensure the stability of the blade position;

[0016] As a further improvement of the above technical solution: the blade located in the middle of the fixing frame is fixedly mounted on the fixing frame.

[0017] The beneficial effect of this improvement is that when adjusting the spacing of multiple blades, the blades in the middle position remain different, and the blades on both sides move in opposite directions, thereby ensuring the stability of the position of the entire blade during the spacing adjustment process.

[0018] In order to ensure the effective use of the scissor-type linkage mechanism;

[0019] As a further improvement of the above technical solution: the scissor-type connecting rod mechanism consists of a connecting rod 1 and a connecting rod 2 of the same size that are hinged at the head and tail, and the middle ends of the connecting rod 1 and the connecting rod 2 are rotatably sleeved on the outside of the connecting shaft.

[0020] The beneficial effect of this improvement is that the scissor-type connecting rod mechanism composed of the connecting rod 1 and the connecting rod 2 can enable multiple blades to move at the same distance as a whole, thereby realizing rapid adjustment of the blade spacing.

[0021] In order to ensure the stability of the blade;

[0022] As a further improvement of the above technical solution: the blade is further connected to a limit rod, and the limit rod is slidably inserted in the adjustment slot.

[0023] The beneficial effect of this improvement is that the limiting rod cooperates with the connecting shaft to ensure the stability of the blade position, preventing the blade from rotating itself during the rotary tillage process, which affects the rotary tillage effect.

[0024] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

A connecting shaft 112 in the adjustable split blade assembly 11 is slidably inserted in the adjusting slot 103. One end of the connecting shaft 112 is connected to the blade 111, and a scissor-type connecting rod mechanism 113 is rotatably mounted on the connecting shaft 112 and a nut 115 is threadedly connected. Through the structural design of the split blade 111 and the scissor-type connecting rod mechanism 113, the blade spacing of the greenhouse vegetable greenhouse micro-tillage machine can be quickly adjusted;At the same time, combined with the design of the rotatable and lockable rotating arm 8, the tillage depth can be easily adjusted, which significantly improves the convenience of operation, tillage efficiency and planting benefits. The adjusting bracket 4 is an arc-shaped plate structure, and the multiple through holes opened on the adjusting bracket 4 are arranged around the axis of the output shaft of the reduction motor 7. During the rotation of the rotating arm 8 around the axis of the output shaft of the reduction motor 7, the operator can insert the bolt into the through hole of the adjusting bracket 4 opposite to the through hole at the top of the connecting arm 5, so as to realize fast and effective adjustment of the use height of the adjustable split blade assembly 11. The driving sprocket in the chain transmission mechanism 9 is installed on the output shaft of the reduction motor 7, and the driven sprocket in the chain transmission mechanism 9 is installed at one end of the main shaft 101. The main shaft 101 is rotatably installed on the rotating arm 8. The chain transmission mechanism 9 can stably transmit the power of the reduction motor 7 to the tool holder power shaft 10, which is located on the fixed frame 10 The blade 111 in the middle position is fixedly mounted on the fixed frame 102.
