Description

Technical Field

[0001] The utility model relates to the technical field of farm tools, in particular to a multifunctional combined farm tool provided with a 7-shaped clamping plate. Background Technique

[0002] Farm tools are labor tools used by farmers in the process of agricultural production. There are many types of farm tools, and different farm tools need to be selected according to different operation requirements. Most of the existing farm tools currently on the market have relatively single functions. Therefore, when carrying out agricultural production, in order to meet different operation requirements, a large number of farm tools are often needed for one labor. However, the agricultural production site is generally far from the farm tool storage place and the transportation is inconvenient. If there is no suitable vehicle to transport the farm tools, and only relying on manpower to transport the farm tools, it is very difficult to carry multiple different-function farm tools back and forth at one time. Sometimes, it can only be achieved by making multiple round trips to replace the farm tools, which is very inconvenient. Moreover, the expenditure cost for farmers to equip various different-function farm tools is also relatively high.

[0003] Therefore, there is an urgent need on the market for farm tools integrated with more functions to relieve the inconvenience caused by farmers having to carry too many different-function farm tools at the same time during one labor, and at the same time reduce the expenditure cost of farm tools. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multifunctional combined farm tool provided with a 7-shaped clamping plate, which can realize different use functions through different combination methods, so as to reduce the number of farm tools to be carried during labor and reduce the expenditure cost of farm tools for farmers.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A multifunctional combined farm tool provided with a 7-shaped clamping plate is assembled by combining two major parts: a handle assembly and a farm tool head assembly.

[0007] The handle assembly is provided with a horizontal transverse handle made of a round steel pipe, and a 7-shaped clamping plate is fixedly connected to the front end of the handle; the 7-shaped clamping plate is a 7-shaped bent plate formed by bending a strip of flat steel into an angle less than 90°, and one end of the bent plate extends horizontally backward as the first clamping head of the 7-shaped clamping plate, and the other end of the bent plate extends obliquely upward and backward as the second clamping head of the 7-shaped clamping plate. Both the first clamping head and the second clamping head are isosceles trapezoidal ends with the same slope, narrow at the head and wide at the tail; two lower openings are provided at the front and rear positions in the middle of the left and right of the plate surface of the first clamping head, and two through holes vertically penetrating the pipe body are provided on the front and rear of the pipe body at the front end of the handle. The pipe body at the front end of the handle is placed inside the bend of the 7-shaped clamping plate and fits against the plate surface of the first clamping head. Two vertical bolts sequentially pass through the lower openings of the first clamping head and the through holes of the handle pipe body from bottom to top and then are screwed with fixing nuts for locking, thereby fixedly connecting the 7-shaped clamping plate to the front pipe body of the handle; a gap is left between the front end of the handle and the second clamping head. The end of the vertical bolt closer to the front end of the handle is provided with two fixing nuts, an eye bolt is hung on the screw rod between the two fixing nuts of the vertical bolt. An upper opening for the screw rod of the eye bolt to pass through loosely is provided at the position in the middle of the left and right and above the handle pipe body on the plate surface of the second clamping head. The screw rod of the eye bolt is bent forward and upward at a certain angle and then penetrates the upper opening in a direction perpendicular to the plate surface of the second clamping head. Locking nuts are respectively screwed on both sides of the plate surface of the second clamping head for double-sided clamping of the second clamping head, and the inclination angle of the second clamping head is locked by the eye bolt to prevent the inclination angle of the second clamping head from changing during labor. Adjusting the positions of the two locking nuts to cause forced deformation of the second clamping head can finely adjust the inclination angle of the second clamping head.

[0008] The farm tool head assembly is provided with a connecting seat, a shovel head, a clamping plate and fixing screws; the connecting seat is provided with a seat body connected to the shovel head, a set of screw holes are provided on the bottom surface of the seat body, and a vertically arranged upper-narrow-lower-wide clamping head slot matching with the two clamping heads of the 7-shaped clamping plate is fixedly connected to the rear end of the seat body. The clamping head slot is composed of two U-shaped slot pieces with spaced-apart left and right slot openings, and the two U-shaped slot pieces are respectively fixedly connected to the left and right side plates of the seat body; a set of fixing holes are provided at the rear end of the shovel head at the position in the middle of the left and right. The seat body of the connecting seat is placed above the fixing holes on the top surface of the shovel head, the clamping plate is placed below the fixing holes on the bottom surface of the shovel head, a perforation is provided on the clamping plate, and the fixing screws sequentially pass through the perforation of the clamping plate and the fixing holes of the shovel head from bottom to top and then are screwed into the screw holes on the bottom surface of the seat body of the connecting seat, thereby fixedly connecting the connecting seat and the shovel head into one body.

[0009] When the shovel head of the farm tool head assembly faces forward and is inserted into the second chuck of the handle assembly through the chuck slot, the gap between the front end head of the handle and the second chuck can avoid the position interference of the front end head of the handle on the inserted position. The interval between the two U-shaped slot pieces of the chuck slot can avoid the position interference of the screw rod of the eyebolt and the lock nut on the inserted position, enabling the insertion to be in place completely to form a lock. At this time, the combined farm tool is a shovel-shaped farm tool; when the shovel head of the farm tool head assembly faces downward and is inserted into the first chuck of the handle assembly through the chuck slot, the interval between the two U-shaped slot pieces of the chuck slot can avoid the position interference of the vertical bolt and the front end pipe body of the handle on the inserted position, enabling the insertion to be in place completely to form a lock. At this time, the combined farm tool is a hoe-shaped farm tool.

[0010] The shovel head is an ax-shaped shovel head. The front side edge of the shovel head is provided with an outward convex arc-shaped cutting edge, and the left and right side edges of the shovel head are provided with inward concave arc-shaped cutting edges. Setting it as an ax-shaped shovel head can utilize its cutting edge to complete functions similar to chopping with an ax or a hatchet, thereby further increasing the applicable range of the farm tool.

[0011] This multi-functional combined farm tool is formed by setting a 7-shaped clamping plate with two chucks in different stretching directions on the handle assembly, and then selectively assembling the farm tool head assembly onto the second chuck or the first chuck of the 7-shaped clamping plate, thus forming a shovel-shaped farm tool or a hoe-shaped farm tool, and further realizing different usage functions. By designing the shovel head into an ax-shaped shovel head with a front cutting edge and left and right side cutting edges, functions similar to chopping with an ax or a hatchet can be completed using its cutting edge. Therefore, using this farm tool can achieve multiple functions such as shoveling, hoeing, chopping, and splitting. It can not only reduce the number of farm tools that need to be carried during labor but also reduce the cost of farm tool expenditure for farmers. In addition, the second chuck of the 7-shaped clamping plate of this farm tool can also finely adjust the inclination angle, and when forming a shovel-shaped farm tool, it can achieve fine adjustment of the elevation angle of the shovel head to obtain better labor effects.

The front end pipe body of the handle 1 is placed inside the bend of the 7-shaped clamping plate 2 and is in contact with the plate surface of the first clamping head 2.1. Two vertical bolts 3 pass through the lower openings 2.3 of the first clamping head 2.1 and the through holes 1.1 of the pipe body of the handle 1 from bottom to top in sequence, and then are screwed with fixing nuts 4 to be locked, thereby fixedly connecting the 7-shaped clamping plate 2 to the front end pipe body of the handle 1. There is a gap between the front end of the handle 1 and the second clamping head 2.2. At the end of the vertical bolt 3 closer to the front end of the handle 1, there are two fixing nuts 4 up and down. A loop bolt 5 is hung on the screw rod between the two fixing nuts 4 of the vertical bolt 3. An upper opening 2.4 for the screw rod of the loop bolt 5 to pass through loosely is provided at the center position of the plate surface of the second clamping head 2.2 and above the pipe body of the handle 1. The screw rod of the loop bolt 5 is bent forward and upward at a certain angle and then penetrates the upper opening 2.4 in the direction perpendicular to the plate surface of the second clamping head 2.2. Locking nuts 6 are respectively screwed on both sides of the plate surface of the second clamping head 2.2 of the screw rod of the loop bolt 5 to clamp the second clamping head 2.2 on both sides, and the inclination angle of the second clamping head 2.2 is locked by the loop bolt 5 to prevent the inclination angle of the second clamping head 2.2 from changing during labor. By adjusting the positions of the two locking nuts 6 to cause forced deformation of the second clamping head 2.2, the inclination angle of the second clamping head 2.2 can be finely adjusted.

[0028] Further, an arc washer 7 that fits the outer wall of the handle 1 is provided between the fixing nut 4 at the end of the vertical bolt 3 farther from the front end of the handle 1 and the outer wall of the handle 1.

[0029] The farm tool head assembly is provided with a connecting seat 8, a shovel head 9, a clamping plate 10 and a fixing screw 11; the connecting seat 8 is provided with a seat body connected to the shovel head 9, a set of screw holes 8.1 are provided on the bottom surface of the seat body, and a vertically arranged upper-narrow and lower-wide clamping head slot 8.2 matching the two clamping heads 2.1 and 2.2 of the 7-shaped clamping plate 2 is fixedly connected to the rear end of the seat body. The clamping head slot 8.2 is composed of two U-shaped slot pieces 8.3 with spaced-apart left and right notches. The two U-shaped slot pieces 8.3 are respectively fixedly connected to the left and right side plates of the seat body; a set of fixing holes 9.1 are provided at the middle position of the rear end of the shovel head 9. The seat body of the connecting seat 8 is placed above the fixing holes 9.1 on the top surface of the shovel head 9, the clamping plate 10 is placed below the fixing holes 9.1 on the bottom surface of the shovel head 9, a perforation 10.1 is provided on the clamping plate 10, and the fixing screw 11 passes through the perforation 10.1 of the clamping plate 10 and the fixing holes 9.1 of the shovel head 9 from bottom to top and then is screwed into the screw holes 8.1 on the bottom surface of the seat body of the connecting seat 8, thereby fixedly connecting the connecting seat 8 and the shovel head 9 into one body.

[0030] When the shovel head 9 of the farm tool head assembly faces forward and is inserted onto the second clamping head 2.2 of the handle assembly through the clamping head slot 8.2, the gap between the front end of the handle 1 and the second clamping head 2.2 can avoid the position interference of the front end of the handle 1 on the insertion position. The interval between the two U-shaped slot pieces 8.3 of the clamping head slot 8.2 can avoid the position interference of the screw rod of the eyebolt 5 and the locking nut 6 on the insertion position, enabling the insertion to be in place completely to form a lock. At this time, the combined farm tool is a shovel-shaped farm tool; when the shovel head 9 of the agricultural machine head assembly faces downward and is inserted onto the first clamping head 2.1 of the handle assembly through the clamping head slot 8.2, the interval between the two U-shaped slot pieces 8.3 of the clamping head slot 8.2 can avoid the position interference of the vertical bolt 3 and the front end pipe body of the handle 1 on the insertion position, enabling the insertion to be in place completely to form a lock. At this time, the combined farm tool is a hoe-shaped farm tool.

[0031] Further, a stamping boss 9.2 is provided at the position of the fixing hole 9.1 on the top surface of the shovel head 9, the fixing hole 9.1 is opened on the stamping boss 9.2, and the clamping plate 10 and the screw head of the fixing screw 11 sink into the stamping groove 9.3 corresponding to the stamping boss 9.2 on the bottom surface of the shovel head 9 to prevent the screw head of the clamping plate 10 and the fixing screw 11 from protruding from the bottom surface of the shovel head 9 and affecting the use. Furthermore, the shovel head 9 is provided with multiple stamping reinforcing ribs 9.4, and the middle stamping reinforcing rib 9.4 is integrally connected with the stamping boss 9.2 to increase the strength of the shovel head 9.

[0032] Further, the shovel head 9 is an ax-shaped shovel head, an outwardly convex arc-shaped cutting edge 9.5 is provided on the front side edge of the shovel head 9, and inwardly concave arc-shaped cutting edges are provided on the left and right side edges of the shovel head 9. Setting it as an ax-shaped shovel head can utilize its cutting edge to complete functions similar to chopping with an ax, thereby further increasing the applicable range of the farm tool.

[0033] When the multi-functional combined farm tool is in use, the tool head assembly is selectively assembled onto the second chuck 2.2 or the first chuck 2.1 of the 7-shaped chuck 2, and then a spade-shaped farm tool or a hoe-shaped farm tool can be combined, thereby realizing different usage functions. By designing the spade head 9 into an axe-shaped spade head with a front edge and left and right side edges, the chopping function similar to that of an axe can be completed by using its cutting edge.

[0034] In addition, the spade head 9 can also be replaced with a farm tool head with other functions, as long as it can be assembled into one body with the connecting seat 8, so as to realize other functions.
