Description

Technical Field

[0001] The utility model belongs to the field of agricultural machinery, and in particular relates to a rotary tillage blade group mechanism. Background Art

[0002] With the continuous updating of science and technology, the degree of agricultural mechanization is constantly improving. When planting crops and fruits and vegetables on a large scale, rotary tillers are generally used in advance to plow the land and turn the soil. Rotary tillers have the characteristics of strong soil crushing ability and flat surface after plowing. At the same time, they can cut up the root stubble buried below the surface. When planting crops and fruits and vegetables on a large scale, rotary tillers are generally used in advance to plow the land and turn the soil, so as to provide a good seed bed for later sowing.

[0003] The rotary tiller blade mechanism is one of the important components of the rotary tiller. The rotary tiller blades in the existing rotary tiller blade mechanism are generally directly installed on the shaft rod. When the rotary tiller blades need to be deeply cleaned and maintained later, the rotary tiller blade mechanism must first be disassembled from the rotary tiller, and then the rotary tiller blades must be disassembled from the shaft rod one by one. After cleaning and maintenance, the rotary tiller blades must be installed on the shaft rod one by one. The entire disassembly and installation process is relatively troublesome, time-consuming and labor-intensive. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a rotary tiller blade mechanism, aiming to solve the problem that the process of disassembling and installing the rotary tiller blades of the existing rotary tiller blade mechanism is troublesome, time-consuming and labor-intensive.

[0005] The utility model adopts the following technical solutions:

[0006] The rotary tiller blade group mechanism includes a rotating seat, a main shaft is arranged in the rotating seat, both ends of the main shaft are sequentially connected with an intermediate sleeve and a plurality of connecting sleeves, at least one rotary tiller blade assembly is arranged on the intermediate sleeve and the connecting sleeve, the rotary tiller blade assembly includes a fixed plate, a pair of rotary tillers are arranged on the inner and outer sides of the fixed plate, and the four rotary tillers are evenly arranged in the circumferential direction, and a rotating mechanism for driving the main shaft to rotate is arranged in the rotating seat.

[0007] Furthermore, the connecting sleeve includes a long sleeve and a short sleeve, the outer diameter of the short sleeve is smaller than the outer diameter of the long sleeve, and the outer diameter of the short sleeve matches the inner diameter of the middle sleeve.

[0008] Furthermore, the rotating mechanism includes a turbine and a worm rotatably installed in the rotating seat, the turbine and the worm are meshingly installed, the main shaft is provided on the turbine, and a driving motor for driving the worm to rotate is provided on the top of the rotating seat.

[0010] Furthermore, a connecting seat is provided at the front end of the rotating seat, and a connecting frame is provided at the rear end, and a plow is provided at the end of the connecting frame through a locking bolt.

[0011] The beneficial effect of the utility model is that when the rotary tiller blade group mechanism needs to be deeply maintained and cleaned later, the rotary tiller blade group mechanism is first disassembled from the rotary tiller, and then the corresponding rotary tiller blade assembly is disassembled. If the rotary tiller blade assembly installed on the connecting sleeve needs to be disassembled, the fixing bolts used to install the connecting sleeve and the intermediate sleeve need to be unscrewed first, and then the connecting sleeve is pulled out from the intermediate sleeve. At this time, the entire rotary tiller blade assembly on the connecting sleeve is disassembled, and then the rotary tiller blade can be disassembled.

[0012] After the rotary tiller blades are maintained and cleaned, they are installed one by one on the fixed plate as required. Then, the short sleeve in the connecting sleeve is inserted into the sleeve opening of the middle sleeve. After it is inserted into place, the connecting sleeve is fixed to the middle sleeve with the fixing bolts.

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0018] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.

[0019] Combination Figure 1-3As shown, the rotary tiller blade group mechanism includes a rotating seat 1, a main shaft 2 is arranged in the rotating seat 1, both ends of the main shaft 2 are sequentially connected with an intermediate sleeve 3 and a plurality of connecting sleeves 4, at least one rotary tiller blade assembly is arranged on the intermediate sleeve 3 and the connecting sleeve 4, the rotary tiller blade assembly includes a fixed plate 5, a pair of rotary tillers 6 are arranged on the inner and outer sides of the fixed plate 5, and the four rotary tillers 6 are evenly arranged along the circumferential direction, and a rotating mechanism for driving the main shaft 2 to rotate is arranged in the rotating seat 1.

[0020] When planting crops, fruits and vegetables on a large scale, rotary tillers are generally used to plow the land in advance to provide a good seed bed for later sowing.

[0021] When the rotary tiller plows the land, the rotating mechanism first drives the main shaft to rotate, and the middle sleeve and the connecting sleeve located at both ends of the main shaft rotate and drive all the rotary blade components to rotate, so as to complete the plowing and turning of the land.

[0022] In the rotary tiller blade assembly mechanism, both ends of the main shaft are sequentially connected with an intermediate sleeve and a connecting sleeve. The intermediate sleeve is provided with a pair of rotary tiller blade assemblies, and the connecting sleeve is provided with a rotary tiller blade assembly, and the three rotary tiller blade assemblies on the same side are evenly arranged, so that the quality of soil turning can be better during the actual plowing and soil turning process.

[0023] As a preferred structure, as shown in FIG. Figure 1 , Figure 3 The connecting sleeve 4 includes a long sleeve 41 and a short sleeve 42. The outer diameter of the short sleeve 42 is smaller than the outer diameter of the long sleeve 41, and the outer diameter of the short sleeve 42 matches the inner diameter of the intermediate sleeve 3. The main shaft and the intermediate sleeve, the connecting sleeve and the intermediate sleeve are all locked by fixing bolts.

[0024] In the present structure, the intermediate sleeve and the connecting sleeve are both detachable installation structures, and at least one rotary tiller blade assembly is provided on the intermediate sleeve and the connecting sleeve. When the rotary tiller blade assembly mechanism needs to be deeply maintained and cleaned later, the rotary tiller blade assembly mechanism is first removed from the rotary tiller, and then the corresponding rotary tiller blade assembly is removed. If the rotary tiller blade assembly installed on the connecting sleeve needs to be removed, the fixing bolts used to install the connecting sleeve and the intermediate sleeve need to be unscrewed first, and then the connecting sleeve is pulled out from the intermediate sleeve. At this time, the entire rotary tiller blade assembly on the connecting sleeve is removed.

[0025] The rotary tiller blades are mounted on the fixing plate via mounting bolts. By unscrewing the mounting bolts, the four rotary tillers are disassembled one by one, after which the rotary tillers can be deeply maintained and cleaned.

[0026] After the rotary tiller blades are maintained and cleaned, they are installed one by one on the fixed plate according to the requirements. Then, the short sleeve in the connecting sleeve is inserted into the sleeve opening of the middle sleeve. After it is inserted into place, the connecting sleeve is fixed to the middle sleeve with the fixing bolts. At this time, the entire rotary tiller blade assembly is installed on the rotary tiller blade assembly mechanism. The entire disassembly and installation process is relatively simple, saving time and effort.

[0027] Further as a preferred structure, Figure 2 The rotating mechanism includes a turbine 7 and a worm 8 rotatably installed in the rotating seat 1. The turbine 7 and the worm 8 are meshingly installed. The main shaft 2 is provided on the turbine 7. A driving motor (not shown in the figure) for driving the worm 8 to rotate is provided on the top of the rotating seat 1.

[0028] When rotary tilling, the driving motor drives the worm to rotate, and the worm drives the turbine to rotate. At this time, the main shaft rotates, and all the rotary tiller blade components rotate synchronously to rotary till the land.

[0029] like Figure 1 The rear end of the rotating seat 1 is provided with a connecting frame 10, and the end of the connecting frame 10 is provided with a coulter 12 through a locking bolt 11. In this structure, the coulter has a plurality of adjustment holes evenly opened along the height direction, and the locking bolt can be inserted into the corresponding adjustment hole 13 to adjust the installation height of the coulter. In this mechanism, the quality of rotary tillage is improved by setting the coulter.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
