Description

Technical Field

[0001] The utility model relates to the technical field of land preparation and ditch opening equipment, and particularly relates to a land preparation and ditch opening integrated machine. Background Art

[0002] Agricultural land preparation machinery mainly consists of components such as disc harrows, subsoilers, soil crushers, and press rollers, which can perform operations of fine crushing and loosening of the plough layer, surface leveling, and compaction of the soil at one time. The land preparation machinery is divided into two types: active type and passive type according to the driving method. Among them, the active type has a high soil crushing rate and good passability, and can adapt to both dry land and paddy field operations. Among them, the driving harrow is the most common and widely used type of active soil crushing machinery. The power harrow refers to a machine that uses the power output shaft of a tractor, drives the working components through a universal joint drive shaft and a transmission system to perform dry land soil crushing and land preparation operations. Currently, common power harrows can usually be divided into reciprocating power harrows, horizontal rotary power harrows, and vertical rotary power harrows, and are used in cooperation with cylindrical blade harrows to complete soil breaking and soil crushing operations at the same time.

[0003] For some fields, it is necessary to carry out ditch opening treatment after soil breaking and soil crushing for sowing some seeds. However, the rear end of the existing land preparation integrated machine often does not have a ditch opening structure and cannot carry out ditch opening treatment immediately after land preparation. Although some land preparation equipment has a ditch opening structure installed at the rear end, the installation position of the ditch opening structure is fixed, resulting in often only being able to carry out ditch opening treatment with fixed spacing and fixed depth, and unable to carry out ditch opening with different spacing and different depth for different plants or different seeds, resulting in insufficient overall universality.

[0004] Therefore, it is very necessary to invent a land preparation and ditch opening integrated machine to solve the above problems. Summary of the Utility Model

Vertical movable holes are opened on both sides of the movable ditch-opening teeth. Screws are detachably inserted into the installation holes, and second nuts are threadedly sleeved on the screws;

[0010] When it is necessary to lock the movable ditch-opening teeth at different height positions of the fixed ditch-opening teeth, the screws can be locked at different heights in the movable holes by rotating the second nuts.

[0011] As a preferred solution of the present invention, the sheet harrow shell frame includes two side frames at symmetric positions, a connecting rod provided between the sides of the side frames, and a plurality of reinforcing frames provided between the connecting rods.

[0023] The present utility model will be further described below in conjunction with the attached drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0024] The present utility model provides a land preparation and ditch opening integrated machine as shown in Figures 1-5 Figure 1, which includes a driving harrow shell frame 1 that can walk from right to left, a sheet harrow shell frame installed on the right side of the driving harrow shell frame 1, and a plurality of cross frames 24. A driving harrow structure for breaking the ground can be installed at the bottom of the driving harrow shell frame 1. A cylindrical sheet harrow 6 for crushing the ground is detachably and rotatably installed inside the sheet harrow shell frame. U-shaped vertical frames 13 are provided at symmetrical positions on the top of the driving harrow shell frame 1 and the sheet harrow shell frame. A plurality of fixing holes 14 are opened on both vertical sides of the U-shaped vertical frame 13, and the distance between the fixing holes 14 is the same as the height of the cross frame 24. The cross frame 24 can be clamped and fixed between two adjacent fixing holes 14 on the same vertical side. A connecting L-shaped mounting frame 17 is connected between the right ends of the plurality of cross frames 24. A plurality of fixed ditch-opening teeth 18 are welded to the bottom end of the L-shaped mounting frame 17. Each fixed ditch-opening tooth 18 can be installed with a movable ditch-opening tooth 19 at different longitudinal heights. The driving harrow structure belongs to a mature prior art and is not drawn in the figure.

[0025] A stud 15 can be inserted between two fixing holes 14 at the same height on both vertical sides of the U-shaped vertical frame 13, and threaded sleeves of first nuts 16 are provided on the parts of both ends of the stud 15 located outside the U-shaped vertical frame 13. When it is necessary to lock the longitudinal height of the cross frame 24 in the U-shaped vertical frame 13, the cross frame 24 is moved to an appropriate position, and the two studs 15 are inserted into two adjacent groups of fixing holes 14, so that one stud 15 contacts the top of the cross frame 24, and the other stud 15 contacts the bottom of the cross frame 24. Finally, the position of the stud 15 in the fixing hole 14 is locked by rotating the first nut 16, and then the position of the cross frame 24 in the U-shaped vertical frame 13 is locked. The position of the cross frame 24 is fixed by the two U-shaped vertical frames 13 together, which can improve the position fixing stability of the cross frame 24.

[0026] Both the fixed ditch-opening teeth 18 and the movable ditch-opening teeth 19 are L-shaped, and mounting holes 20 are opened on both sides of the fixed ditch-opening teeth 18, and the height positions of the two mounting holes 20 are different. Vertical movable holes 21 are opened on both sides of the movable ditch-opening teeth 19. Screws 22 are detachably inserted into the mounting holes 20, and threaded sleeves of second nuts 23 are provided on the screws 22. The bottom of the movable ditch-opening teeth 19 is trapezoidal, which is convenient for inserting into the soil. The longitudinal heights of the two mounting holes 20 are different, which can avoid interference between the two screws 22;

[0027] When it is necessary to lock the movable ditch-opening teeth 19 at different height positions of the fixed ditch-opening teeth 18, the screws 22 can be locked at different heights in the movable holes 21 by rotating the second nuts 23.

[0028] The blade harrow housing includes two side frames 3 at symmetrical positions, a connecting rod 4 disposed between the side edges of the side frames 3, and a plurality of reinforcing frames 5 disposed between the connecting rods 4. A cylindrical blade harrow 6 is rotatably disposed between the two side frames 3. One set of U-shaped upright frames 13 is symmetrically disposed at the top of the driving harrow housing 1, and the other set of U-shaped upright frames 13 is symmetrically disposed at the top of the two reinforcing frames 5. By respectively disposing the two sets of U-shaped upright frames 13 at the top of the driving harrow housing 1 and the blade harrow housing, a locking position of the cross frame 24 exists at the top of both the driving harrow housing 1 and the blade harrow housing, which can improve the position fixing stability of the cross frame 24.

[0029] The right end of the driving harrow housing 1 is fixedly connected to a connecting rod 4 on the left side through a connecting plate 2. The connecting plate 2 fixedly connects the driving harrow structure and the blade harrow structure, thereby synchronously completing the soil breaking and soil pulverizing operations.

[0030] A plurality of soil pulverizing tooth discs 7 are sleeved on the circumferential side wall of the cylindrical blade harrow 6, and the distances between adjacent two soil pulverizing tooth discs 7 are the same. Extension card seats 8 are connected to the right end portions of both side frames 3. A connecting column 9 is disposed between the extension card seats 8. A mounting seat 10 is detachably installed on the portion of the connecting column 9 located between the two soil pulverizing tooth discs 7. A scraping blade 12 is installed at the bottom end of the mounting seat 10 through an arc-shaped connecting frame 11. The scraping blade 12 can scrape and clean the clay on the circumferential side wall of the cylindrical blade harrow 6. The cylindrical blade harrow 6 rotates following the driving harrow structure, and the soil pulverizing tooth discs 7 perform soil pulverizing treatment on the cultivated land after soil breaking. However, some clay may adhere to the circumferential side wall of the cylindrical blade harrow 6, and it can be timely scraped off by the scraping blade 12 to avoid affecting the soil pulverizing effect of the cylindrical blade harrow 6.

[0031] In this utility model, during the process of the entire device moving from right to left, first, the driving harrow structure is used to break the soil of the field, and then the cylindrical blade harrow 6 is used to crush the soil synchronously to complete the soil preparation operation of the field. On the right side of the cylindrical blade harrow 6, a ditching structure is provided, namely the fixed ditching teeth 18 and the movable ditching teeth 19. By installing the movable ditching teeth 19 at different longitudinal heights of the fixed ditching teeth 18, the ditching depth can be finely adjusted. At the same time, by installing the movable ditching teeth 19 on the fixed ditching teeth 18 at different positions, the adjustment of the ditching spacing is completed. After the position of the movable ditching teeth under the L-shaped mounting frame 17 is locked, by changing the fixed position of the cross frame 24 between the fixing holes 14 in the U-shaped vertical frame 13, the longitudinal height of the cross frame 24 in the U-shaped vertical frame 13 is changed, so as to greatly adjust the longitudinal height of the L-shaped mounting frame 17, that is, to greatly adjust the longitudinal heights of the fixed ditching teeth 18 and the movable ditching teeth 19, thereby completing the major adjustment of the ditching depth. In this application, after the soil preparation treatment, the ditching treatment can be synchronously completed subsequently to realize the integrated treatment of soil preparation and ditching. Moreover, the ditching depth can be finely adjusted and greatly adjusted, and at the same time, the adjustment of the ditching spacing can also be completed, so as to dig ditches with different spacings and different depths for different plants or different seeds, improving the universality and adjustability of the entire device.

[0032] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present utility model, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
