Abstract

The utility model discloses a crawler type salt harvester, which comprises a crawler travel mechanism, a salt-harvesting harrow and a salt discharge mechanism; a rack is arranged on a chassis of the crawler travel mechanism; the upper end of the salt-harvesting harrow is rotatably mounted on the rack, and a hydraulic cylinder is hinged between the middle part of the salt-harvesting harrow and thechassis; and the salt discharge mechanism is mounted on the rack. The utility model can normally operate on a salt field, the bottom of which has bearing strength larger than 0.08MPa and the salt deposit of which is less than 400mm thick, the salt-harvesting efficiency is greatly increased, the salt-harvesting cost is reduced, meanwhile, the loss of crude sale is reduced, and the salt harvester isparticularly suitable for the production of lake salt in the northwestern region in China.

Description

The track type salt harvester

Technical field

The utility model relates to a kind of salt harvester.

Background technology

Salt harvester is the specific equipment that salt industry is produced, and known wheeled salt harvester mainly is applicable to the sea salt district, requires the crystallizing pond area in salt pan to be not less than 1000 square metres, and bearing resistance is not less than 0.15MPa at the bottom of the pond, below the salt layer thickness 120mm.Ground such as China Inner Mongol, Qinghai abound with lake salt, the characteristics in local salt pond are softer at the bottom of the pond, and bearing resistance is low at the bottom of the pond, and the salt layer thickness is big, and road is uneven, common wheeled salt harvester can't use at all, therefore, continues to use the primary mode of operation in these areas always, the workman reaps pool side with strainer with crude salt, heap with spades, labour intensity is big again, and production efficiency is extremely low.

As applicant of the present utility model, be devoted for years to exploitation, design and production in salt industry machinery, have rich practice experience.Through contriver's painstaking efforts and performing creative labour, developed a kind of salt harvester that uses under salt lake region or the complicated salt pond condition that is applicable to finally.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of track type salt harvester is provided, this salt harvester can be at the bottom of the pond bearing resistance low, the salt layer thickness is big, and uses in the up-and-down salt pond of road.

For solving the problems of the technologies described above, the technical solution of the utility model is: the track type salt harvester, comprise running gear, and the chassis of described running gear is provided with frame; Receive the salt drag head, described receipts salt drag head is installed on the described frame; The salt take-off equipment, described salt take-off equipment is installed on the described frame; Described running gear is a crawler unit, and the upper end of described receipts salt drag head is rotated and is installed on the described frame, is hinged with hydro-cylinder between the middle part of described receipts salt drag head and the described chassis.

Wherein, described receipts salt drag head comprises a vertically arranged spiral conveyer and a drag conveyer mutually, described drag conveyer is arranged at the mid-way of spiral conveyer, the turning axle of described spiral conveyer is provided with two sections screw-blades, and both sides and rotation direction that described screw-blade lays respectively at described drag conveyer are opposite.

Wherein, described salt take-off equipment comprises a rotary conveyor, and the throughput direction of described rotary conveyor is vertical with the throughput direction of institute's drag conveyer.

After having adopted technique scheme, the beneficial effects of the utility model are: because described running gear is crawler unit, the contact area of traveling crawler and salt deposit is big, has reduced the specific pressure over the ground of salt harvester, has effectively reduced the destruction of salt harvester at the bottom of to the pond.Simultaneously, because the upper end of described receipts salt drag head is rotated and is installed on the described frame, be hinged with hydro-cylinder between the middle part of described receipts salt drag head and the described chassis, can adjust the receipts salt degree of depth of receiving the salt drag head by hydro-cylinder, also can receive the salt drag head and make salt harvester normally walking on up-and-down road by the hydro-cylinder adjustment.The utility model can be at the bottom of the pond bearing resistance greater than 0.08MPa, salt layer thickness salt pan works better less than 400mm, improved receipts salt efficient greatly, reduced receipts salt cost, simultaneously, reduced the crude salt loss.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the front view of the utility model embodiment;

Fig. 2 is the left view of Fig. 1;

Among the figure, 1. crawler unit; 11. chassis; 2. receive the salt drag head; 21. spiral conveyer; 22. drag conveyer; 3. rotary conveyor; 4. hydro-cylinder.

Embodiment

Shown in Fig. 1 and Fig. 2 are common, a kind of track type salt harvester, it comprises crawler unit 1, the chassis 11 of described crawler unit is provided with frame.The upper end rotation of receiving salt drag head 2 is installed on the described frame, is hinged with hydro-cylinder 4 between the middle part of described receipts salt drag head and the described chassis 11.

Described receipts salt drag head 2 comprises a vertically arranged spiral conveyer 21 and a drag conveyer 22 mutually, described drag conveyer 22 is arranged at the mid-way of spiral conveyer 21, the turning axle of described spiral conveyer 21 is provided with two sections screw-blades, and both sides and rotation direction that described screw-blade lays respectively at described drag conveyer 22 are opposite.During work, salt is lived in being cut and is compiled to the centre, and transmits backward by drag conveyer 22.

Rotary conveyor 3 is installed on the described frame, and the salt that it is used for collecting is transported to carrier vehicle.The throughput direction of described rotary conveyor 3 is vertical with the throughput direction of described drag conveyer 22, and carrier vehicle can be walked side by side with salt harvester like this.

Characteristics of the present utility model are:

1, running gear adopts caterpillar belt structure, has reduced over the ground specific pressure of salt harvester, and specific pressure is even, can not damage the pond The end.

2, receiving the salt drag head can adjust up and down, receives the salt degree of depth and reaches 400mm, receives the salt amount and reaches 200t/h, receives the salt worker Make device and running gear and both can work simultaneously, but independent operation again.

The utility model can be at the bottom of the pond bearing strength greater than 0.08MPa, the salt layer thickness salt pan less than 400mm Normal operation has improved receipts salt efficient greatly, has reduced receipts salt cost, simultaneously, has reduced the crude salt loss, Be particularly suitable for the lake salt production in NORTHWEST CHINA area.
