Abstract
The utility model provides a power-saving hoe, which can improve labor postures, and reduce the degree of fatigue. The utility model belongs to the technical field of hand tools, and is composed of a hoe head and a hoe rod, and also a hoe handle sometimes. The utility model is characterized in that a handle is arranged on the hoe bar. After being provided with the handle, the utility model has the advantages that amplitude of stoop action for workers is reduced, and thus, the effects of improving the labor postures and lightening the degree of the fatigue are attained. The utility model does not change the prior art for making a hoe, the price is not increased a lot, but the received effects are obvious. The utility model is simple and convenient operation for both users and producers, and is easy to accept by each party. The utility model has a wide popularization foreground particularly in capital construction and transportation, and occasions mainly used for stirring and assembly and disassembly. The utility model can be used for tools such as a spade, a shovel, a hoe, a harrow, etc.
Description
The utility model relates to a kind of digging tool.Belong to the hand-operated tools technical field.
Spade is a kind of common tool.Numerous areas such as capital construction, traffic, digging, agricultural, military affairs all are widely used.Traditional spade is by shovel head, spade bar, also have the spade handle to form sometimes.The spade bar is generally straight-bar, it simple in structure but when using operator's movement range of bending over bigger, tired easily.The gardener Peter of Queensland who quotes Britain " New Scientist " weekly first phase introduction on April 9 on May 26th, 1994 " Reference News " is taken " work efficiency type " spades of root invention.It swells the middle part of bar as hump, thereby has improved labour posture, has reduced tired degree, it is said, can economize 30% power when loading-unloading vehicle at least.Yet hump shape spade bar makes its rigidity reduce.Cause distortion of spade bar and damage when digging easily at the shovel of exerting oneself, if thicken tube wall in order to improve rigidity, weight and cost will be increased, and the manufacturing of this all steel goods is complicated, the cost costliness is difficult to each use department of China and accepts.
The purpose of this utility model is exactly to design a kind of laborsaving spade of suitable China's national situation, and it had both kept improving the advantage of labour posture, is connected with the use habit and the manufacturing process of China existing spade again, can promote rapidly in China.The technical scheme that the utility model proposed also can be used for similar tool such as shovel, shovel, hoe, rake.
The utility model also has the spade handle to form by shovel head, spade bar sometimes, it is characterized in that: on the spade bar handle is set.
Laborsaving spade spade bar can be wooden, also can be metal or plastic.
Handle can adopt multiple version, for example:
Scheme one, the normal formula handle is as Fig. 1.(1) is shovel head among the figure, and (2) are the spade bar, and (3) are the spade handle, and (4) are handle, and (5) are connector, and (6) are keeper, (7) be securing member (following number in the figure identical all be part with title, no longer repeat).Handle is made by metal or plastic tube
Shape or
Shape.For metal spade bar, handle can be with bolt directly fixing or welding (comprise adding the sleeve pipe soldering, down with) on shaft; To the wooden winnowing spade bar, available connector connects; To plastics spade bar, above-mentioned various types all can be considered.
To the wooden winnowing spade bar, can also adopt the form of similar common spade handle, connector is prolonged, garden cylindricality or dolioform wooden handle is fixed thereon.
Scheme two, T-shaped handle, Fig. 2 are its handle portion sketch, and handle can be used the tenon fourth of the twelve Earthly Branches or connector, and perhaps the tenon fourth of the twelve Earthly Branches adds connector, connects with wooden spade bar, then can adopt scheme one described various coupling methods between metal or plastics spade bar and the handle.
Scheme three, readily removable handle, Fig. 3 are its handle portion sketch, handle is
Shape, direction also can be opposite as figure, also can be provided with sheath (8) on it, and sheath can be with plastics or rubber parts.Have wedged hole on the connector, the corresponding part of handle is also made wedge shape, can pull down easily when not needing handle.
The shape handle also can be directly with bolt, or is welded on the shaft, perhaps adopts the fixed form of scheme one.
Scheme four, collapsible handle, Fig. 4 is its handle portion sketch, handle (4) is supported by front support rod (9) and back support rod (10), with rivet pin (11), (12), (13), removable pin (14) connects, and pulls down removable pin, back support rod can be buckled on the spade club body, front support rod and handle are buckled on the back support rod, with removable pin handle and spade bar are fixed again, promptly be can be used as conventional spade and use, as shown in Figure 5, the shape stability of quadric chain can be guaranteed by the shape of support bar herein, for example support bar can be a channel, controls notch size d(Fig. 7 of it and spade bar intersection), make C that support bar can only be in Fig. 4 to rotation.
More than the distance b of handle height a and handle and spade handle (or spade rod rear end) in each scheme, length and homework type on the spade bar are decided, numerical value is at a ≈ 150~300mm, in the scope of b ≈ 400~600mm, spade to some specific type, when its total length during less than 900mm, the numerical value of b can also be littler.
Row for two example two below.
Embodiment one, and by the laborsaving spade of a kind of normal formula bend pipe handle of scheme one design, handle is contained on the wooden spade bar, and bend pipe can be made with the thin-wall steel tube of φ 25~φ 30, and the part of wherein holding can be with rubber or plastic bushing.Connector is stamped to form with steel plate, as Fig. 6.Locate with two rivet pins or garden nail between connector and the spade bar.Use screws clamp between connector and the handle.The long 1000mm of present embodiment spade, a=200mm, b=430mm.Present embodiment is simple in structure, and is easy to manufacture, only bores two holes (boring does not influence intensity on neutral surface) on the spade bar of common spade, and mounting knob gets final product, and is easy to realize that price can not increase much yet on the basis of existing system spade technology.
Embodiment two, by the laborsaving spade of a kind of T-shaped handle of scheme two designs.The cross bar of handle and vertical rod are all available makes with spade bar same diameter or slightly thin material, and both connect with the tenon fourth of the twelve Earthly Branches, and available connector is fixed between vertical rod and the spade bar, and connector can adopt the form of similar embodiment one.Present embodiment is not only simple in structure, and is contained in and seems on the wooden spade bar of present widely used T-shaped handle and very coordinate.The long 1100mm of spade in this example, a=250mm, b=500mm.
In sum, the technical scheme that the utility model proposed has reached not only to be improved labour posture but also tallies with the national condition, promote the use of the user and the producer all simple and easy to do, especially in capital construction, transportation with mainly be the prospect that the occasion that is used to stir, load and unload has extensive popularization.
