Background technology

Chinese patent 95204564.8 disclosed " multi-functional spade ", it contains the shovel head and the pick of band spade handle, pick and shovel head are fixed in the two ends of a lug respectively, lug is connected on the connecting rod with the affixed one of spade handle with bearing pin by the axis hole on it, and has one on the connecting rod and can make pick, shovel head be stabilized in positioning sleeve on the operating position.Spade, the pick that existing multi-functional spade has, uproot, cut four kinds of functions, make people just can finish multi-mode operation with a spade, both reduced people go out must with number of tools, can improve operating efficiency again; But it also has following weak point: 1) it lacks the function of saw, so some more sturdy weedtrees, withered bamboo etc. are removed in inconvenience; 2) strength that its spade handle length is unadjustable, people are difficult for performance oneself, it is lower to pretend industry efficient.

Summary of the invention

The utility model is to overcome in the above-mentioned prior art deficiency that also exists, and a kind of farm spade that can hoe,scrape, cut, saw and shave is provided, so that it has characteristics such as the more complete and adjustable-length of function.

The farm spade of the utility model energy hoe,scrape, cut, saw and shave, it contains the shovel head and the pick of band spade handle, pick and shovel head are fixed in the two ends of a lug respectively, lug is connected on the connecting rod with the affixed one of spade handle with bearing pin by the axis hole on it, and have one on the connecting rod and can make pick and shovel head be stabilized in positioning sleeve on the operating position, it is characterized in that: a side of shovel head has sawtooth, side has blade in addition.

The farm spade of the utility model energy hoe,scrape, cut, saw and shave, its spade handle is split-type structural, and it comprises threaded two sections, and these the two sections thread bush with adjustable spade handle length overall connect; The internal thread at thread bush two ends is respectively left-hand thread and right-hand thread, and the screw thread on each section spade handle respectively with thread bush in left and right threads engaged.

The beneficial effects of the utility model are: 1) its function because of having shovel simultaneously, uprooting, scrape, cut, saw, dig, pretend the industry personnel and only need be with the utility model spade can be in farming, woods, foundation engineering construction, and various operations such as flood fighting is got rid of the danger, finish shovel in the earthquake relief work, uproot, scrape, cut, saw, plane; 2) its spade handle length is conveniently adjusted, so people can adjust spade handle length according to the needs of oneself, in order to putting out one's full powers, improve operating efficiency; 3) compared with prior art, the utility model spade just increases sawtooth, the spade handle is carried out segmentation and with the thread bush connection, so the utility model is rational in infrastructure simple, helps renovating to existing spade on shovel head.

Embodiment

The farm spade of embodiment 1. present embodiments energy hoe,scrape, cut, saw and shave, its structure can see from Fig. 1, Fig. 2, Fig. 3 and Fig. 5, Fig. 6 that it contains the shovel head 1 and the pick 5 of band spade handle 7, and the upside of shovel head has sawtooth 1b, downside has blade 1a; Pick and shovel head are fixed in the two ends of a lug 2 respectively, the right-hand member that wherein shovel head 1 is fixed in the rivet hole 9a of lug 2 left ends with rivet 9, pick 5 is welded on lug 2 by pad 4, lug then is connected on the connecting rod 8 with a bearing pin 3 by the pin shaft hole 3a that has on it, this connecting rod while and spade handle 7 chimeric affixed one.Depression 8a and a positioning sleeve 6 of having a built-in pick 5 on the connecting rod 8 to be threaded, its pocket 8a can be for pick in that the time spent collect in it, positioning sleeve 6 then can be by rotation to hold out against the sidewall of lug left, so that pick 5 or shovel head 1 are stabilized on the operating position; Perhaps change spade, pick state and before rotating lug, first positioning of rotating cover 6, it is removed to the right, treat that pick after hiding depression 8a, makes positioning sleeve screw to left again, with the pick in the locking depression at needs.

When using the farm spade that present embodiment can hoe,scrape, cut, saw and shave, can directly press configuration state illustrated in figures 1 and 2, with its shovel head and blade 1a, sawtooth 1b shovel, uproot, scrape, cut, operation such as saw; If positioning of rotating cover 6 makes lug 2 make counter-clockwise direction around bearing pin 3 and rotates 90 °, promptly transfer Fig. 3 state to from Fig. 2 state, then do out of trade except do to shovel, uproot, scrape, cut, saw etc., its pick 5 can dig the hole, at this moment also can lock lugs, guarantee that pick or spade are firmly motionless in operation by positioning sleeve 6.If counter-rotating positioning sleeve 6, so that it withdraws from from depression 8a, the switching lug 2 again, so that making clockwise direction around bearing pin 3, it rotates 90 °, promptly get back to the state of Fig. 2, and then positioning of rotating cover 6 is locked in pick 5 in the depression 8a, guarantees job safety from Fig. 3 state.

Embodiment 2. present embodiments can hoe,scrape, cut, saw and shave the structure of farm spade can from Fig. 4, see, it as different from Example 1 spade handle 7 be split-type structural, it comprises threaded left side section 7a and right section 7b, and left and right two sections connect with thread bush 10.It makes people rotate left side section 7a or right section 7b according to needs separately, so that these two sections length adjustment of drawing close mutually or separating, realizing spade handle 7 are convenient for people to exert oneself in operation.

The screw thread at above-mentioned thread bush 10 two ends preferably is respectively left-hand thread, right-hand thread, and the screw thread on two sections 7a, the 7b of the split of spade handle then is complementary with the left and right screw thread at thread bush two ends respectively.At this moment can realize left and right two sections the drawing close mutually or separate of spade handle as long as rotate thread bush 10, make the adjusting of spade handle length faster.
